摘要: Disclosed are 1,7-disubstituted perylene-3,4,9,10-tetracarboxylic acid dianhydrides (I) and acids (Ia) in which R represents optionally substituted aryloxy, arylthio, hetaryloxy or hetarylthio. Also disclosed the production of these compounds their use as pigments, laser dyes precursors for fluorescent dyes, polymer colorants, pigments pigment additives, well diimides (VI) intermediate products compounds.
