Abstract
Dyes, a term which often includes pigments, are chemicals that are intensely coloured or impart colour to natural products, textiles, food and drugs, consumer products, and synthetic products. They work by being adsorbed onto or held mechanically by the substrate; by the formation of ionic, covalent, and complex bonds; or by forming solutions. Dyes are distinguishable from pigments by the manner in which they are applied: dyes often lose their physical form by dissolution, often being water-soluble, although they may regain a crystalline form after application; pigments retain their physical form, often being held in suspension like the pigments in paint. Tens of thousands of metric tons of dyes and pigments, inorganic and organic, are produced worldwide each year.
