  Selected chlorohydrin and cationic compounds containing nitroxide or hydroxylamine moieties are effective in stabilizing pulp or paper, especially pulp or paper containing lignin, against yellowing and discoloration due to the adverse effects of light. These compounds are added at various points in the paper-making process, especially at the wet ends, making the need for water soluble or water dispersible materials having high affinity for pulp or paper essential. This performance is often further enhanced by the presence of one or more coadditives selected from the group consisting of the UV absorbers, the polymeric inhibitors, the nitrones, the fluorescent whitening agents and metal chelating agents. Combinations of hydroxylamines or their salts, benzotriazole or benzophenone UV absorbers and a metal chelating agent are particularly effective.

  选择的含氮氧自由基或羟胺基团的氯水合物和阳离子化合物对于稳定纸浆或纸张，特别是含有木质素的纸浆或纸张，抵御光的不良影响导致的黄变和变色非常有效。这些化合物在造纸过程的各个阶段添加，特别是在湿端，需要具有高亲和力的水溶性或水分散材料是必不可少的。这种性能通常通过存在于紫外线吸收剂、聚合物抑制剂、亚硝基、荧光增白剂和金属螯合剂等组中选择一个或多个共添加剂来进一步增强。羟胺或其盐、苯并三唑或苯并酮紫外线吸收剂和金属螯合剂的组合特别有效。
