ABSTRACT:
Compounds selected from the series consisting of the perylenecarboximide, quinacridone, isoindoline, indigoid, azo, benzodipyrrolone, chromophores containing at least one grouping of formula ##STR1## wherein each A may be N--CN or O, with the proviso that at least one A must be N--CN, X is --N(R)--, --O-- or --S--, R is hydrogen, C.sub.1 -C.sub.18 alkyl, unsubstituted or halogen- or C.sub.1 -C.sub.4 alkyl-substituted phenyl, benzyl or phenethyl, and m and n are each independently of the other 0 or 1.
Depending on the nature of their substituents, these compounds can be used as polymer-soluble dyes or as pigments for coloring high molecular weight organic material. They are distinguished by a surprisingly high solid-state fluorescence.
