光稳定性是衡量高分子染料的一个重要指标,而高分子染料的光稳定性主要与高分子骨架结构、染料母体结构及着色工艺等因素有关。本文详细分析了高分子染料光褪色的原因及机理,并针对影响高分子染料光稳定性的各因素,提出相应的改进措施。
Photostabilization is an important property of polymeric dye, which is affected by the polymer, dye structure and dyeing method. The photofading mechanisms of the polymeric dye were discussed and the method to improved light fastness was proved.
