Zusammenfassung:	To provide such a fine coated azo lake pigment that a coloring agent using the coated azo lake pigment has high transparency and high tinctorial power.SOLUTION: There is provided a carboxylic acid compound coated azo lake pigment in which a ratio between mixed enthalpy of a carboxylic acid compound and an azo lake pigment and mixed enthalpy of the carboxylic acid compound and water is a specific ratio. A coloring agent using the carboxylic acid compound coated azo lake pigment, and a manufacturing method of the carboxylic acid compound coated azo lake pigment are also provided.SELECTED DRAWING: None 【課題】微細な被覆アゾレーキ顔料が得られ、該被覆アゾレーキ顔料を用いた着色剤は、高い透明性、および高着色力となる。【解決手段】カルボン酸化合物とアゾレーキ顔料の混合エンタルピーおよびカルボン酸化合物と水の混合エンタルピーの比が特定の比率である特徴を有するカルボン酸化合物被覆アゾレーキ顔料。また、該カルボン酸化合物被覆アゾレーキ顔料を用いる着色剤、および該カルボン酸化合物被覆アゾレーキ顔料の製造方法。【選択図】なし
