Procedure

The phthalocyanine derivative prepared in Referential Example or the other material was added, in a proportion shown in Table 7, to 10 parts of the TiOPc crude prepared in Example 1, and mixed together and then the mixture was gradually dissolved in 200 parts of 97% sulfuric acid solution at 2° C., and the resulting mixture was stirred for 1 hour with maintaining its temperature at not higher than 5° C. Then, this sulfuric acid solution was slowly poured into 2000 parts of ice water with stirring at a high speed, and crystals precipitated were filtrated. The crystals were washed with distilled water until the acid did not remain, and then dried to give a titanium phthalocyanine compound.
