The invention relates to a water-soluble polymeric dye comprising an anionic or nonionic chromophore unit covalently bound to a polymer backbone, wherein the polymer backbone is based on a water-soluble anionic or nonionic polymer and the polymer backbone comprises a) at least 2.5 anionic functional groups or at least 5 hydroxyl functional groups, or a combination thereof, per average chromophore unit for an anionic chromophore unit or b) at least 3.5 anionic functional groups or at least 7 hydroxyl functional groups, or a combination thereof, per average chromophore unit, for an nonionic chromophore unit. The polymeric dye according to the invention has good skin and fabric washability, and can be applied in paints and ink formulations for use markers and ink jet cartridges.
该发明涉及一种水溶性聚合物染料,包括一个阴离子或非离子色团单元与聚合物骨架共价结合,其中聚合物骨架基于水溶性阴离子或非离子聚合物,且聚合物骨架包括:a)每个阴离子色团单元至少2.5个阴离子功能基或至少5个羟基功能基,或其组合,对于阴离子色团单元;或b)每个非离子色团单元至少3.5个阴离子功能基或至少7个羟基功能基,或其组合,对于非离子色团单元。根据该发明的聚合物染料具有良好的皮肤和织物可洗性,并可应用于油漆和墨水配方中,用于标记笔和喷墨打印机墨盒。
