摘要：
Disclosed are cationic polymeric dye with a hue value of h=210° to 330° comprising: a) a polymer backbone, b) a residue of an organic dye, and c) optionally colorless organic groups, wherein (b) and (c) are covalently bound to the polymer backbone (a), and wherein the cationic charges can independently be part of the dye or the colorless organic groups. The dyes are distinguished by their depth of shade and their good fastness properties to washing, such as, for example, fastness to light, shampooing and rubbing.
