Procedure

A mixture of 70 weight parts of C.I. Pigment Red 122 CROMOPHTAL Jet Magenta DMQ” (produced by Ciba Japan 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 6 was obtained.
