摘要： PROBLEM TO BE SOLVED: To provide a process for producing a quinacridone pigment. SOLUTION: A reaction mixture which comprises an ingredient (i) comprising 2,5-dianilinoterephthalic acid, a 2,5-dianilino-6,13-dihydroterephthalic ester, and/or a derivative thereof, a dehydrant (ii) in an amount of about 3-15 pts.wt. per pt. of the ingredient (i), and at least one nonquinacridone pigment (iii) in an amount of about 0.1-15wt.% based on the ingredient (i) is heated at about 80-145 deg.C. When the ingredient (i) is the ester or derivative thereof, the above step is followed by the oxidation step. The reaction mixture is then added to a liquid in which the resultant quinacridone pigment is substantially insoluble in such a proportion that the amount of the liquid is about 3-15 pts.wt. per pt. of the ingredient (i). The quinacridone pigment is isolated, if necessary conditioned, and if necessary blended with one or more quinacridone derivatives.

(b) drowning the reaction mixture from step (a) by adding said reaction mixture to about 3 to about 15 parts by weight, per part of component (a)(i), of a liquid in which the quinacridone pigment is substantially insoluble;
(c) isolating the quinacridone pigment;
(d) optionally, conditioning the quinacridone pigment; and
