Pigment And Dye is a colored material that is completely or nearly insoluble in water. In contrast, dyes are typically soluble, at least at some stage in their use. Generally dyes are often organic compounds whereas pigments are often inorganic compounds Dioxide Titanium. Pigments of prehistoric and historic value include ochre, charcoal, and lapis lazuli.
A dye is a colored substance that chemically bonds to the substrate to which it is being applied. This distinguishes Ethylene-Vinyl Acetate dyes from pigments which do not chemically bind to the material they color Black Iron Oxide . Dye is generally applied in an aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber.
Both dyes and pigments are colored, Titanium Dioxide Food Grade because they absorb only some wavelengths of visible light. Dyes are usually soluble in water whereas Sodium Hexametaphosphate pigments are insoluble. Some dyes can be rendered insoluble with the addition of salt to produce a lake pigment.
