Abstract

Isoindoline compounds of the formula (I) ##STR1## and their metal complexes of the formula (II) ##STR2## where (in formulae (I) and (II)) X and Y are each hydrogen, fluorine, chlorine, bromine, alkyl, alkoxy, alkoxycarbonyl, alkylsulfonyl, alkanoylamino, carbamyl, nitro, benzoylamino or N-phenylcarbamyl, or X and Y together form a radical of a fused benzene ring, T is fluorine, chlorine or bromine, Z is nitro, carbamyl, alkanoylamino, alkoxy, alkyl or phenyl, n and n' are each 0, 1, 2, 3 or 4, p and p' are each 0 or 1, the sums (n+p) and (n'+p') are each not more than 4, and Me is a divalent cation of a transition metal, of zinc or of cadmium, are useful pigments or coloring polymers, printing inks and finishes.
