PROCEDURE

实验过程

was cyclized in phosphoric acid to form 2,9-dichloroquinacridone. The phosphoric acid containing the thus-formed 2,9-dichloroquinacridone was dispersed in water, and the 2,9-dichloroquinacridone (crude C.I. Pigment Red 202) was then sufficiently washed, dried and pulverized to obtain Quinacridone pigment composition (2-5).
