Abstract
Abstract 1:1 metal complexes of isoindolinazines of the formula ##STR1## in which the ring A can be further substituted, R is a hydrogen atom or an alkyl or aryl group, B is an isocyclic or heterocyclic aromatic radical, R 1 is the OH or SH group and Y is a radical of the formula ##STR2## in which Z 1 and Z 2 are O or S atoms, n is the number 1 or 2, R 2 ' is an alkyl, aryl or heteroaryl radical and R 2 is an alkyl, cycloalkyl, aralkyl or aryl radical or a radical of the formula ##STR3## in which R 3 is an alkylene or arylene group. The novel pigments color plastics and surface coatings in pure, intense orange to red shades with good fastness properties.
