An industrially preferred process for producing an isothiazole compound, particularly 3,4-dichloro-5-cyanoisothiazole, provides a safer industrial production process by avoiding the simultaneous use of an aprotic polar solvent such as N,N-dimethylformamide and chlorine. In addition, a production process which is economically preferred because an aprotic polar solvent, which is highly likely to become a part of waste, is not used. A process for producing an isothiazole compound represented by a general formula (3), wherein R is a cyano group or the like; and X is a chlorine atom or the like, which comprises heating a nitrile compound represented by a general formula (1), wherein R is as defined above, and sulfur, and then carrying out a reaction between the nitrile compound represented by the general formula (1), the sulfur and a halogen represented by a general formula (2), wherein X is as defined above.


The present invention is a metal phthalocyanine polymer comprising a repeating structural unit obtained by amide bonding of a structural unit represented by general formula (1a) to a structural unit represented by general formula (2a). (wherein L is a divalent or trivalent metal ion belonging to Group 3 to Group 5 on the long-form periodic table.) (wherein M is a divalent or trivalent metal ion belonging to Group 3 to Group 5 on the long-form periodic table.)
