ABSTRACT:
New diazo pigments of the formula ##EQU1## wherein A denotes a phenylene or naphthylene radical and R denotes an aromatic radical containing a --CONH-- group bonded in a cyclic structure are prepared. The pigments are useful for coloring high-molecular organic materials such as polyamides, polyurethanes or polyesters. The pigments have good fastness to light, migration and weathering.
