ABSTRACT:
A method for producing a novel phthalocyanine compound which excels in yield and purity, allows no introduction of a chlorine atom into the phthalocyanine skeleton, and possesses relatively bulky substituents is provided. This method is characterized by causing an orthophthalonitrile compound having a substituent exhibiting smaller .sigma..sub.p values than .sigma..sub.m values in the Hammett's rule to react with a metal oxide in the presence of a compound forming in the aqueous solution thereof at 25.degree. C. an acid or conjugate acid having a dissociation index pKa (the logarithmic value of the reciprocal of the dissociation constant of the acid or conjugate acid) of not more than 7.0.
