Procedure

A mixture of 70 weight parts of C.I. Pigment Red 122 FASTOGEN Super Magenta RE-25 (produced by Dainippon Ink Chemical Co., Ltd.), 290 weight parts of isobutanol and 380 weight parts of water were stirred at 130° C. for 7 hours in a stirrer. Thereafter, the resulting mixture was cooled to room temperature, and the resulting precipitates were filtered off, washed with hot water, dried and pulverized. Thus, Quinacridone Pigment 8 was obtained.
