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.
揭示了一种带有色调值为h = 210°至330°的阳离子聚合染料,包括:a)聚合物骨架,b)有机染料残基,以及c)可选的无色有机基团,其中(b)和(c)与聚合物骨架(a)以共价键结合,阳离子电荷可以独立地成为染料或无色有机基团的一部分。这些染料以其色深和对洗涤的良好耐久性特性而区分,例如对光、洗发水和摩擦的耐久性。
