The aforesaid 3-a phthalocyanine derivative (0.5 parts) was added to 10 parts of the TiOPc crude prepared in Example 1 and mixed together. The mixture was added to 80 parts of 78% sulfuric acid at 10° C. and the resulting solution was stirred for 1 hour with maintaining its temperature at not higher than 10°. The solution was poured into 400 parts of water, and precipitated crystals were filtrated. The crystals were washed with distilled water until the acid did not remain, and dried to give titanium phthalocyanine compound.
