Compounds of formulaA(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, 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 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 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-R9 are as defined herein.
