Reaction Steps

10 g of dimethoxysilicon phthalocyanine synthesized in Synthesis Example 2 was added to 10 g of water and 90 g of N,N-dimethylformamide (90% DMF aqueous solution) and reacted at 120° C. for 3 hours. The reaction product was thermally filtrated and washed with DMF and acetone in the order named. After the product was stirred in 50 ml of acetone at room temperature, crystals were separated by filtration and dried to obtain 8.4 g of dihydroxysilicon phthalocyanine. As the result of carrying out structural analysis by mass spectrum (negative measurement) and IR spectrum (KBr method), the same spectra as those of Example 22 were obtained. Therefore, it was confirmed that the product was dihydroxysilicon phthalocyanine.
