    摘要： Compounds of formula A(B)x,  (I) wherein x is an integer from 1 to 4, A is the radical of a chromophore of the quinacridone, anthraquinone, perylene, indigo, quinophthalone, isoindolinone, isoindoline, dioxazine, phthalocyanine or azo series, which radical contains x N-atoms attached to B, preferably with at least one directly adjacent or conjugated carbonyl group, B is a group of formula  and, if x is 2, 3 or 4, may also be one, two or three hydrogen atoms. The symbols Q, R1, R2, R3, R4, X, Y, Z, m and n, are as defined in claim 1. These carbamate group-containing soluble chromophores are distinguished by outstanding solid state fluorescence in the UV range as well as the by ease with which they can be converted to the corresponding pigments in the substrate in which they are incorporated.

    摘要： 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.
