   Dye       Dyes are colorants made of single molecules that absorb certain parts of the spectrum of visible light while reflecting others. Dyes are soluble in the material in which they are dispersed. 
   Pigment       Pigments are finely ground, powdery substances and one of the basic components of paint or caulk. They provide paint with properties such as color, hiding power, bulk, durability, and corrosion resistance. The term "pigment" includes extenders, as well as white or color pigments. Pigments are insoluble in the material in which they are dispersed. 
   Dry Powder       Traditionally, pigments are supplied as dry powders or granules to producers of inks and coatings. Dry powder pigment offers the widest possible choice of grades available. Consequently, it allows the formulator a high degree of flexibility. 
   Masterbatch - Liquid / Paste       As the name implies, these are masterbatches or concentrated dispersions of organic or waterborne pigments that contain solvents or diluents. These dispersions can be free flowing pourable liquids or high-viscosity pastes depending on the composition. Depending on the specified end use, they may contain resins, additives or surfactants. Due to their fully dispersed nature, this family of dispersions is readily incorporated by means of simple low energy mixing equipment requiring no additional dispersion. 
   Masterbatch - Pellets / Solid       This category of masterbatches or concentrate dispersions includes pre-dispersions of pigment supplied in dry form either as dust free pellets, granules or flakes. They do not contain solvents but may contain additives or plasticizers. The two common forms that typify this category are chips and Predisol pigment preparations.  As these are in solid form, they do not have the pigment level limitations found with paste or liquid dispersions, due to the handling difficulties encountered with high rheology pastes. Pigment levels of between 50% and 70% are achievable, depending on the pigment and resin type. The high pigment-to-binder ratio achievable from some specialist dispersions minimizes the content of dispersing resin, which opens up the possibilities of developing multi use concentrates, a highly desirable production capability.

Color / Appearance
   Color / Appearance      Primary pigment is commonly composed of titanium dioxide.  The amount of primary pigment impacts greatly on the hiding capabilities of the paint film and UV protection.  Secondary pigments are pigments such as talc, silics, calcium carbonate, mica, etc., which have little impact on hiding.  They are basically used as fillers to help control viscosity, leveling, sheen, etc.

   Your choices are...         
   Acid Dyes       Acid dyes are anionic colorants that are characterized by substantiality for protein and polyamid fibers. Typically, they are applied from an acidic or neutral dye bath. 
   Aniline Dyes       Aniline (CAS #62-53-3) is a colorless to brown oily liquid with an aromatic, pungent odor. It is used in the manufacturing of resins, varnishes, perfumes, printing inks, cloth marking inks, paint removers, photographic chemicals, explosives, herbicides, fungicides, rigid polyurethanes, optical whitening agents, and shoe blacks. It is used as a solvent, and as a chemical intermediate for rubber processing, accelerators, corrosion inhibitors, dyes and pigments, specialty resins, cyclohexylamine, hydroquinine, pesticides such as alachlor, pharmaceuticals such as sulfonamides, 4-anilinophenol, and methylenediisocyanate. 
   Azo Dyes       Azo dyes are the largest group of dyes, with –N=N– as a chromophore, in aromatic systems. Depending on the number of azo groups present, products are called monazo, disazo, trisazo, tetrakisazo and polyazo dyes. Diazotisation of a primary amine in the presence of HCl + NaNo2 at a freezing temperature produces a diazonium salt which, in turn, is coupled with aromatic compounds to produce an azo dye. There are over one thousand types of azo dyes. These products represent the most important commercial class of synthetic coloring compounds. They have a variety of applications and include lake dyes. 
   Anthraquinone Dyes       The basic unit for this class of products is anthraquinone. Anthraquinone is faint yellow in color, sufficient for use as a dye, but cannot be classified as a dye. The introduction of hydroxyl and amino groups provides a wide range of colors. Dyes containing an anthraquinone unit belong to mordant, disperse and vat dyes. The quinonoid system acts as a chromophore. Anthraquinone dyes have excellent fastness properties. 
   Direct / Substantive Dyes       Direct or substantive dyes are anionic dyes with substantivity for cellulosic fibers. Normally, they are applied from an aqueous dye bath that contains an electrolyte. 
   Disperse Dyes       Disperse dyes are generally used to dye cellulose acetate, nylon and other hydrophobic fibers. They are also known as acetate dyes. Sulphoricin oleic acid (SAR) is used as the dispersing agent. Dispersal and cellitoin are the important dispersing agents. 
   Laser Dyes       Laser dyes are a lasing medium composed of complex fluorescent organic dyes dissolved in organic solvents. 
   Reactive Dyes       There are three main types of reactive dyes: procion dyes, remazol (sulphone dyes), and disperse dyes. 
   Solvent Dyes       Solvent dyes provide color by dissolving in the target material, which is invariably a lipid or non-polar solvent. 
   Sulfur Dyes       Water-insoluble dyes contain sulfur both as an integral part of the chromophore and in attached polysulfide chains.  They are normally applied in an alkaline-soluble reduced form, from a sodium sulfide solution, and subsequently oxidized to the insoluble form in the fiber. 
   Other Dyes       Other unlisted dye types. 
   Barium Metaborate       Borates have water solubility greater than 0.2% and should be carefully formulated to avoid stability problems. 
   Barium Sulphate       Barium sulfate is a white, soluble, heavy compound obtained either from the natural mineral barytes, or by chemical treatment of barium and sulfuric acid. It is highly transparent, which improves printability. It is also used to form the pigment lithopone, which is also known as "blanc fixe". 
   Raw Sienna       Raw siennas are unique shades of natural yellow with a brownish undertone. 
   Burnt Sienna       Burnt siennas are brownish shades with good transparency and heat stability characteristics. They are used extensively in producing mahogany, cherry, and rosewood colored stains.  They are also used by the art material industry to produce flesh tones when combined with titanium dioxide white. 
   Raw Umber       Raw umbers are an excellent value in brown pigments and popular in the stain industry due to their transparency.  Though they are not heat-stable, raw umbers can be used to produce many warm gray tones.  They are also used extensively by colorant houses to darken a color without seriously affecting its chromaticity. 
   Burnt Umber       Burnt umber is a calcimined version of raw umber, which changes its ability to absorb light. This process leads to its redder-orange color. Burnt umber tints white to light beige and tans, and is universally accepted as a pigment for brown oil stains. 
   Carbon Black       Carbon black is a black, amorphous, carbon pigment produced by the thermal decomposition of natural hydrocarbons. There are three different types: furnace, channel, and lamp black. 
   Chromium Oxide       Chromium oxide is a compound of chromium and oxygen. It is often used in alloys. 
   Fluorescent       Pigment that absorbs light at one wavelength and responds by emitting light at another wavelength; the emitted light is of longer wavelength (and hence of lower energy) than the light absorbed. 
   Inorganic       Inorganic pigments are useful mainly where high opacity is needed. Inorganic pigments do not contain carbon. 
   Iron Oxide       Iron oxide is available as a natural or synthetic product. In terms of tonnage, ochre is the major iron oxide. Tuscan red and yellow ocher are popular iron oxides. 
   Lead Carbonate       Lead white, white lead, flake white, and Cremnintz white are names given to synthetic lead carbonate pigment. 
   Natural       Natural dyes and pigments are refined from native ores and earths by physical and chemical treatments, which convert these crude coloring matters into improved pigments with the desirable color and pigment properties. 
   Phosphorescent       Photoluminescence occurs naturally in many minerals and metallic compounds, in some types of organic compounds, and in some living organisms such as marine fauna and fireflies. Phosphorescence is distinguished from fluorescence in two ways:
  1. There is a longer time period between excitation and the emission of light, ranging from one-thousandth of a second to several hours, whereas fluorescence occurs almost instantaneously, and
  2. Phosphorescence may continue for some hours after the excitation source has been removed. The length of emanation depends on the substance, whereas fluorescence ceases when the source is cut off. Thus, phosphorescent materials glow in darkness, but fluorescent materials do not.
 
   Organic       Organic pigments refer to a wide range of chemical families and covers a wide spectrum of properties. They are used mainly for applications requiring high tinting strength and brilliant shades. Organic pigments contain carbon. 
   Strontium Chromate       Strontium chromate is also known as chromic acid strontium salt, C.I. pigment yellow 32, strontium yellow, deep lemon yellow, strontium dichromate, and strontium chromate (VI). 
   Synthetic       Chemical reactions and processes make synthetics from raw materials, which are not in themselves pigments. 
   Titanium Dioxide       Titanium dioxide is the white pigment in virtually all white paints. It is also the prime hiding pigment in most paints. Another name for titanium dioxide is anatase titanium. 
   Zinc Oxide       Zinc oxide is a fine, white, insoluble powder, prepared by the oxidation of pure zinc or by roasting zinc ore. It is used for a variety of purposes; however, the most important is as a paint pigment called zinc white. 
   Zinc Phosphate       Zinc phosphate is a valuable corrosion-resistant pigment that is used extensively in developed countries. This pigment is essentially zinc phosphate dihydrate and corresponds to the formula Zn3 (PO4)2. 2H2O. It is a white, non-toxic pigment prepared by precipitation. 
   Zinc Sulfide       Zinc sulfide (ZnS) occurs naturally as a "blend" and is prepared directly from the elements and precipitation of a zinc salt solution with ammonium sulfide. It is produced at a relatively low cost, so many of its applications are as a substitute for other materials. ZnS is a gray or off-white powder that is insoluble in water, but soluble in acid.
