Compounds of formula A(B)x (?), 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, diketopyrrolopyrrole or azo series, which radical A contains x N-atoms linked with B, preferably with at least one immediately adjacent or conjugated carbonyl group. B is a group of formula <IMG> , and, if x = 2, 3 or 4, can also be one, two or three hydrogen atom(s), and wherein Q is a group of formula <IMG> , <IMG> or <IMG> . These soluble chromophores can be readily converted to the corresponding pigments by heating, even in the substrate into which they can be incorporated without any difficulty in dissolved form. R1-R8 are as claimed in claim 1.
