Vorschrift

The phthalocyanine derivative prepared in Referential Example or the other material was added, in a proportion shown in Table 9, 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 at 2°. The resulting mixture was stirred for 1 hour with maintaining its temperature at not higher than 5° C. And then this sulfuric acid solution was poured slowly 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 dried to give a titanium phthalocyanine compound.
