改良P.R53:1金光红C有机颜料配方和工艺的探讨

Pigment Formulation of Improved P.R53:1 Golden Red C Organic Pigment and Its Process Discussion

对P.R53∶1金光红C有机颜料进行改良,实验表明当其他条件不变,CLT酸与吐氏酸维持总量不变,且质量比例20～21∶1,偶合反应pH=7.5时,可以获得底色稍蓝、有黄色光、强度高、遮盖率好的优良水基有机颜料。

Innovation on P.R53:1 golden red C organic pigment shows that CLT acid and ipecacuanhic acid will not be changed in total amount; at mass ratio 20-21:1 and coupling reaction pH=7.5, an organic pigment can be obtained.
