Abstract: PURPOSE:To obtain cyanometal phthalocyanine crystal having improved stability, molding properties and mechanical handleability and high electrical conductivity, by subjecting a solution containing a dicyanometal phthalocyanine alkali salt to electrolytic treatment. CONSTITUTION:A solution containing a dicyanometal phthalocyanine alkali salt [e.g., dicyanocobalt (III) phthalocyanine sodium salt, etc.] is subjected to electrolytic treatment, to precipitate dicyanometal phthalocyanine crystal. Preferably the prepared crystal is doped with at least one substance selected from an electron acceptive compound (e.g., I, Br, arsenic pentafluoride, etc.) and an electron donative compound (e.g., Li, Na, K, etc.).
