Abstract
The problem addressed by the present invention is to provide a high heat-resistant phthalocyanine. The phthalocyanine is separated by mixing a phthalocyanine separation solvent and a phthalocyanine solution wherein a phthalocyanine starting material is dissolved in a solvent. The phthalocyanine is wherein having high heat resistance, the decomposition temperature of the separated phthalocyanine being at least 10° C. higher than the decomposition temperature of the phthalocyanine starting material. Also, the phthalocyanine solution may be the result of dissolving at least two types of phthalocyanine starting material in the solvent, the separated phthalocyanine being wherein containing a solid solvent of the at least two types of phthalocyanine starting material and by the decomposition temperature of the separated phthalocyanine being at least 10° C. higher than the decomposition temperature of a mixture of at least two types of phthalocyanine separated by mixing the phthalocyanine separation solvent and each of at least two types of phthalocyanine solution resulting from dissolving each of the at least two types of phthalocyanine starting material in a solvent.
