Patent ID: 7713342

Claim:
A phase change ink composition comprising a phase change ink carrier and a colorant compound of the formula wherein M is an atom or group of atoms capable of bonding to the central cavity of a phthalocyanine molecule, wherein axial ligands optionally can be attached to M, each R′ and R″, independently of the others, is a substituent selected from the group consisting of an alkyl group, an aryl group, an arylalkyl group, an alkylaryl group, a nitrile group, a nitro group and an alkoxy group, each n, independently of the others, is, 1, 2, 3, or 4, each m, independently of the others, is 0, 1, 2, or 3, each R, independently of the others, is an alkylene group, an arylene group, an arylalkylene group, or an alkylarylene group, each X, independently of the others, is —OH, —COOH, or a group of the formula wherein each Y and each Z, independently of the others, is a direct bond, an oxygen atom, or a group of the formula —NRI—, wherein R1 is a hydrogen atom, an alkyl group, an aryl group, an arylalkyl group, or an alkylaryl group, provided that Z and Y are not both direct bonds connected to a single C═O moiety at the same time, provided that when X is R can also be a direct bond, and each R˜, independently of the others, is an alkyl group, an aryl group, an arylalkyl group, or an alkylaryl group.
