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.

Abstract: A highly covering disazo pigment having the chemical constitution WHICH IS CHARACTERIZED BY A SPECIFIC SURFACE OF 12 - 30, PREFERABLY 15 TO 25, M2/G, A MAXIMUM OF THE GRAIN SIZE DISTRIBUTION OF BETWEEN 250 AND 500 NM AND A PROPORTION OF THESE GRAIN SIZES IN THE TOTAL DISTRIBUTION OF 35 - 65 PERCENT, PREFERABLY 45 - 60 PERCENT. This new pigment form is obtained by heating the pigment obtained after coupling with a solvent which is immiscible with water or miscible with water to a limited degree only to temperatures above 100 DEG C.
