ABSTRACT:
The invention relates to anthraquinone polysulfonamide colorants derived from colored disulfonyl chlorides containing anthraquinone chromophores by reacting with various diamines. The anthraquinone polysulfonamide colorants are useful for coloring a wide variety of products such as plastics, fibers, films, cosmetics, skin creams or lotions, polishes, waxes, hair colorations, coatings, paints, inks, etc. and are particularly useful in end uses where sublimation, migration, extraction and exudation of presently used colorants are problems.
