PURPOSE:To provide a new phthalocyanine compound, readily soluble in organic solvents such as polar solvents at ambient temperature, excellent in processability such as formation of films and useful especially as optical recording materials. CONSTITUTION:This phthalocyanine compound is expressed by the formula {1 to 16 are each a position of peripheral carbon atom; M is two H atoms or a bivalent metallic atom, oxide or chloride; R is tertiary amino, cyclic imino, an acyloxy or hydroxy; (n) is 1 or 2; R<1> and R<2> are each H or an alkyl, with the proviso that the substituent group introduced into the benzene ring of the phthalocyanine skeleton is bound to any carbon atom(s) at the 2- or 3, 6- or 7, 10- or 11, 14- or 15-position(s) or any carbon atom(s) at the 1- or 4, 5- or 8, 9- or 12, 13- or 16-position(s)}, e.g. tetrat-[2-(piperidinomethyl)-4- methylphenoxy]phthalocyanine. The compound expressed by the formula is obtained by reacting the corresponding phthalonitrile, as necessary, together with a metallic salt, in the presence of 1,8-diazabicyclo[5.4.0]-7-undecene, etc., which is a strong organic base in a solvent such as methanol. |
