    • The invention relates to pyrrolo[3,4-c]pyrroles of formula ##STR1## wherein D and E are each independently of the other hydrogen, C.sub.1 -C.sub.18 alkyl, C.sub.2 -C.sub.4 alkenyl, C.sub.7 -C.sub.10 aralkyl, unsubstituted phenyl or phenyl which is substituted by chloro, bromo, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.4 alkoxy, trifluoromethyl or nitro, or --COO--C.sub.1 -C.sub.5 alkyl or a group --COOR.sub.8,wherein R.sub.8 is benzyl, piperidyl or a group ##STR2## and X and Y are N--CN or O, with the proviso that at least one of X or Y N--CN must be N--CN.These pyrrolo[3,4-c]pyrroles are preeminently suitable for use as colorants, i.e. as pigments or as polymer-soluble dyes, for colouring high molecular weight organic material. They are distinguished by unexpectedly high solid-state fluorescence.The substituents A and B are as defined in claim 1.
    • 本发明涉及式(I)的吡咯并[3,4-c]吡咯,其中D和E各自独立地为另一个氢,C 1 -C 18烷基,C 2 -C 4链烯基,C 7 -C 10芳烷基,未取代的苯基或苯基, 被氯,溴,C 1 -C 6烷基,C 1 -C 4烷氧基,三氟甲基或硝基或-COO-C 1 -C 5烷基或-COOR 8基团取代,其中R 8是苄基,哌啶基或基团,X和Y是N -CN或O,条件是X或Y N-CN中的至少一个必须是N-CN。 这些吡咯并[3,4-c]吡咯非常适合用作着色剂,即作为颜料或作为聚合物可溶性染料用于着色高分子量有机材料。 它们的突出特征是出乎意料的高固态荧光。 取代基A和B如权利要求1中所定义。
