Description
A class of synthetic yellow, orange, and red organic colorants. Diarylide dyes are insoluble direct azo dyes that were first synthesized from benzidine in 1911. They were not widely used until the 1930s. Diarylide yellows have good tinting strength, opacity and solvent resistance. They have fair to good lightfastness and are primarily used in printing inks, plastic, rubbers, as well as architectural and artists paints.
See also Arylide.
