Reaction Steps

A mixture of 70 weight parts of C.I. Pigment Red 122 FASTOGEN Super Magenta RTS (produced by Dainippon Ink Chemical Co., Ltd.), 290 weight parts of isobutanol and 380 weight parts of water was 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 13 was obtained.
