  A pigment composition having a reduced content of o-anisidine as compared to that in the conventional art is provided, and a production method that allows o-anisidine to be efficiently removed in producing the pigment composition is provided. The pigment composition contains: an azo pigment that is a reaction product between a coupler and a base; and a pigment derivative, and a content of o-anisidine derived from the coupler is less than or equal to 20 mg/kg in the entire pigment composition. The method for producing the pigment composition includes, after reaction between a coupler and a base to generate an azo pigment, or during the reaction between the coupler and the base, adding a remover for o-anisidine derived from the coupler.

  本发明提供了一种与传统技术相比邻甲氧基苯胺含量更低的颜料组合物，并提供了一种可在生产该颜料组合物时有效去除邻甲氧基苯胺的生产方法。该颜料组合物包含：偶氮颜料，它是偶联剂与碱的反应产物；以及颜料衍生物，在整个颜料组合物中，由偶联剂衍生的邻甲氧基苯胺的含量小于或等于 20 mg/kg。生产颜料组合物的方法包括，在偶联剂和碱反应生成偶氮颜料后，或在偶联剂和碱反应过程中，加入偶联剂衍生的邻甲氧基苯胺的去除剂。
