Abstract

Azo pigments are prepared by coupling diazo compounds of substituted or unsubstituted aniline or naphthylamine with e.g. 2,3-oxynaphthoic acid, using a phenol dye, in an inert organic solvent with sulphuryl chloride, thionyl chloride, phosphorus tri- or pentachloride, in the presence of a catalytic quantity of dimethyl formamide, and a compound of formula in which A is H or the group -SO2-N(X)-CH2-CH2-CN where X is e.g. -CH2-CH2-CN or pheyl.
