Abstract

By treating perylene-3 : 4 : 9 : 10-tetracarboxylic acid, or a substitution product thereof, with ammonia or primary aromatic or aliphatic amines it is converted into difficultly soluble imides which dye animal and vegetable fibre in fast red to blue-violet shades from the vat. In examples the acid or its ammonium salt is heated with ammonium carbonate, methylamine hydrochloride, or aniline; other suitable amines are p-chloraniline, a or b naphthylamine, a or b -aminoanthraquinone, also diamines such as o-, m-, and p-phenylenediamines, 1 : 8-naphthylenediamine, and benzidine. The perylene 3 : 4 : 9 : 10-tetracarboxylic acid may be prepared by oxidizing with hypochlorite, chromic acid or other oxidizing agent, the vat dyes made by alkali fusion of perinaphthindanone or perinaphthindandione.
