摘要：
Novel bisisoindoline pigments of the formula (I) ##STR1## where the radicals A are identical or different radicals of a methylene-active compound, X is a divalent radical and the rings L are each unsubstituted or substituted, possess good fastness properties and are therefore suitable for a very wide range of applications, for example for pigmenting plastics, printing inks and surface coatings.
