ABSTRACT:
The invention relates to iminoisoindolinone pigments of the formula ##STR1## wherein X is halogen, Y and Z are halogen, C.sub.1 -C.sub.4 alkoxy, or aryloxy, R.sub.1 and R.sub.2 are hydrogen, halogen, C.sub.1 -C.sub.2 alkyl or C.sub.1 -C.sub.2 alkoxy, and A is phenyl which can be substituted by halogen, trifluoromethyl, C.sub.1- C.sub.2 alkyl, C.sub.1 -C.sub.2 alkoxy, or by a group of the formula --CONHR.sub.3 or --NHCOR.sub.4, wherein R.sub.3 is hydrogen, C.sub.1- C.sub.2 alkyl, or phenyl which can be substituted by halogen, methyl, methoxy or trifluoromethyl, and R.sub.4 is phenyl which can be substituted by halogen, methyl or methoxy, or is C.sub.1 -C.sub.2 alkyl, or A is a heterocyclic radical. These pigments are distinguished by particulary excellent color strength and fastness to migration and are suitable for pigmenting organic material of high molecular weight.
