    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.
