Some aspects of organic pigments

Organic pigments are traditionally used in the mass colouration of plastics and synthetic fibres, and in surface coatings such as paints and inks. More recently, they have also found increasing use in a number of high technology industries. Commercial pigments must satisfy many performance criteria, which in turn are determined by their molecular, solid state and particle surface characteristics. This review highlights some of the important aspects of organic pigments which are of importance to both producers and users.
