Reaction Steps

A titanyl phthalocyanine crystal was prepared using the method described in Example 1 of JP-A 03-269064. Specifically, the procedure for preparation of the wet cake in Pigment Synthesis Example 1 was repeated. The wet cake was dried to prepare the TiOPc pigment. One gram of the TiOPc pigment was mixed with a mixture solvent of 10 g of ion-exchange water and 1 g of monochlorobenzene, and the mixture was agitated for 1 hour at 50° C. Then the resultant TiOPc crystal was washed with methanol, followed by washing with ion-exchange water and drying. Thus a TiOPc crystal 4 was prepared. No halogen-containing raw material was used for synthesizing the TiOPc crystal 4.
