Description
A class of synthetic yellow, orange and red organic colorants. These insoluble direct azo dyes were first synthesized from aniline-based diazonium salts and acetoacetarylide in 1909. Arylide was sold commercially as Hansa yellow by Hoechst AG in 1915. Arylide yellows have good tinting strength, opacity and solvent resistance. They have good lightfastness and are primarily used in printing inks, plastic, rubbers, as well as architectural and artists paints. Monoarylide yellows have better lightfastness than diarylides.
Synonyms and Related Terms
monoarylide; diarylide; azo dye; monoazo dye; Hansa yellow; colorante azoico (Esp.); colorante azoico (It.)
