Abstract: A process for improving the properties of Pigment Yellow 17 (Colour Index 21 105) wherein an aqueous suspension of the crude dyestuff prepared in the usual manner by coupling tetrazotized 4,4''-diamino-3,3''-dichloro-diphenyl with 1-acetoacetylamino-2methoxy-benzene is heated for several hours to temperatures between 100* and 200*, preferably 100*C to 150*C, at a pH-value higher than 8, preferably at about 11. Pigment Yellow 17 aftertreated in this way has an essentially better fastness to light than the untreated pigment. Furthermore, the graphic prints produced with it have a higher lustre.

Abstract: Process for the aftertreatment of the azo pigment of the formula C.I. PIGMENT ORANGE 36 wherein the crude pigment obtained after coupling is heated to temperatures from 100 DEG to 150 DEG C. in dry or wet condition in a solvent which is water-immiscible or not indefinitely water-miscible and the pigment is isolated in known manner. The pigment aftertreated in this way shows substantially improved hiding power while the same pigment prepared in the usual way has poor hiding power and can not be used in stoving lacquers.
