CA 2064881

New perylene compounds based on perylene-3,4,9,10-tetracarboxylic monoanhydride monoimides substituted on one or both imide nitrogen atoms by alkylene- or arylenesulphonic groups, or on corresponding tetracarboxylic diimides or on a halogenated product thereof can be used not only as dispersing agents for pigments of the same class of compounds or other categories but also directly as pigments and fluorescent as well as polymer-soluble dyes.

Nouveaux composés de pérylène à base de pérylène-3,4,9,10-tétracarboxylique monoanhydride monoimides qui sont substitués sur un ou les deux atomes d'azote de l'imide par des groupes alcénylènesulfoniques ou arylènesulfoniques, ou sur les diimides tétracarboxyliques correspondant ou sur un de leurs produits halogénés, peuvent être utilisés non seulement comme agents dispersants pour les pigments de la même classe de composés ou non, mais également directement comme pigments et fluorescents et comme colorants solubles dans les polymères.
