ABSTRACT:
A phthalonitrile compound of formula (I); ##STR1## and a diiminoisoindoline compound of formula (II): ##STR2## are allowed to react to produce a phthalocaynine compound of formula (III), ##STR3## which is an effective material for a near-infrared absorbing material and also as a recording material for an optical information recording medium. The methods of producing the phthalonitrile compound of formula (I) and the pthalocaynine compound of formula (III) are proposed.
