Azo pigments of the formula ##EQU1## wherein A is a condensed ring system consisting of a benzene ring and a 5- or 6-membered hetero ring having nitrogen in the cyclus and a keto group, R is alkyl, cycloalkyl or aryl and Y is hydrogen, halogen, alkyl, cycloalkyl, alkoxy, aryl or nitro, and the azo group is not bonded directly to the hetero ring of the diazo component, are prepared. These pigments are useful for coloring organic material of high molecular weight, such as cellulose ethers and esters, and polyesters. Th pigments have excellent fastness to light and migration.
