Abstract
Abstract Formulations of flavanthrone, pyranthrone, indanthrone, indigo, quinacridone, perylene-3,4,9,10-tetracarboxylic acid dianhydride and perylene-3,4,9,10-tetracarboxylic acid diimide pigments which contain, as additives, one or more compounds of the formula ##STR1## where X is an n-valent radical of a flavanthrone, pyranthrone, indigo, quinacridone, perylene-3,4,9,10-tetracarboxylic acid dianhydride or perylene-3,4,9,10-tetracarboxylic acid diimide pigment, R 1 , R 3 and R 4 are hydrogen or chlorine, R 2 is hydrogen, chlorine, carboxyl, bromine, nitro, N-C 1 -C 5 -alkylcarbamyl, N-phenylcarbamyl or benzoylamino and n is 1, 2, 3 or 4. In solutions of surface-coating binders or of surface coatings, the above formulations give very deep colorations, coupled with high gloss and high transparency of the resulting films.
