Abstract

Polyamides, polyurethanes, aminoplasts, phenoplasts, polyethylene, polystyrene, polyvinyl chloride and silicone solutions or products are coloured with a pigment of the formula <FORM:0892092/IV (a)/1> where each A is a substituted or unsubstituted aromatic residue and X is an acylamino or acyloxy group of an aliphatic or cycloaliphatic monocarboxylic acid, which pigment is free from acid groups imparting solubility in water. The pigment may be used for the spin dyeing of viscose or of cellulose ethers or esters.ALSO:The invention comprises dyestuffs which are free from acid groups imparting solubility in water and have the formula <FORM:0892092/IV (c)/1> n which each A is a substituted or unsubstituted aromatic residue and X is an acylamino or acyloxy group of an aliphatic or cycloaliphatic monocarboxylic acid. The dyestuffs are made by treating a quinone free from acid groups imparting solubility in water having the formula <FORM:0892092/IV (c)/2> where X is as above and R represents different or identical aromatic residues each of which has an alkoxy group in ortho-position to the -NH- group, with a non-sulphonating condensing agent at a raised temperature. Condensing agents specified are sulphuric acid, Friedel-Crafts catalysts such as aluminium chloride or iron chloride, and aromatic acid chlorides such as benzoyl or naphthoyl chlorides, benzene sulphochloride and benzene trichloride. The dyestuffs are red to blue pigment dyestuffs. The quinones of the formula (2) above are made by condensing one mol of a benzoquinone of the formula <FORM:0892092/IV (c)/3> with two mols of an o-alkoxy-aromatic amine.
