Reaction Steps

10 g of dimethoxysilicon phthalocyanine synthesized in Synthesis Example 2 was added to 5 g of water and 95 g of N-methylpyrrolidone (95% NMP aqueous solution) and reacted at 115° C. for 3 hours. The reaction product was thermally filtrated and washed with NMP and acetone in the order named. After the product was stirred in 100 ml of acetone at room temperature, crystals were separated by filtration and dried to obtain 8.0 g of dihydroxysilicon phthalocyanine. Structural analysis was carried out by mass spectrum (negative measurement), IR spectrum (KBr method) and elemental analysis. FIG. 34 shows the mass spectrum of dihydroxysilicon phthalocyanine and FIG. 35 shows the IR spectrum thereof. In the mass spectrum, a peak of dihydroxysilicon phthalocyanine was observed at an m/z of 574. A peak at an m/z of 557 is a fragment peak at which one hydroxyl group is removed. In the IR spectrum, absorption special to dihydroxysilicon phthalocyanine was observed at 1,519, 1,066 and 839 cm-1. The results of elemental analysis are shown below and almost agree with calculation values. It was thereby confirmed that the product was dihydroxysilicon phthalocyanine.
