Abstract
Abstract Compositions comprising (a) a pyrrolopyrrole of formula I ##STR1## wherein A and B are identical or different alkyl, arlkyl, aryl or heterocyclic aromatic radicals, R 1 and R 2 are hydrogen atoms, unsubstituted or substituted alkyl radicals, and also alkenyl, alkynyl, aralkyl, cycloalkyl, carbamoyl, alkylcarbamoyl, arylcarbamoyl, alkoxycarbonyl, aryl, alkanoyl or aroyl groups, and X is an --O-- or --S-- atom, and (b) a pyrrolopyrrole of the above formula I that contains at least one group of formula --SO 3 L, --CO 2 L, --PO 3 (L) 2 , --N(R 4 )(R 5 ), ##STR2## or --NHCOR wherein L is --H, a group of formula ##EQU1## or N + H(R 3 )(R 4 )(R 5 ), M is monovalent, divalent or trivalent metal cation, n is 1, 2 or 3, R 3 , R 4 and R 5 are each independently --H or alkyl, aralkyl, C 5 -C 6 cycloalkyl or aryl radicals, or R 4 and R 5 , together with the nitrogen atom to which they are attached, form a 5-- or 6-membered heterocyclic radical, q is an integer from 0 to 4, r is an integer from 3 to 5 and R is aryl or C 1 -C 4 alkyl, are suitable for coloring high molecular organic material.
