PROBLEM TO BE SOLVED : To provide a substituted phthalocyanine having high compatibility to a low polarity solvent or resin.SOLUTION : The phthalocyanine contains at least one or more organosiloxane-containing groups represented by formula (2) at β-position. In the formula (2), Arepresents a single bond or a divalent 1-10C hydrocarbon group, when Ais a divalent hydrocarbon group, the group may have one or more halogen atoms as substituents, or may have one or more heteroatoms; Rare each independently a 1-10C monovalent hydrocarbon group or a 1-10C alkoxy group, and each may be substituted with one or more halogen atoms; n represents an integer of 0-8; and x represents 0, 1 or 2, and when x is 0 or 1, a plurality of OSiRgroups may form a cyclic siloxane through desiloxane condensation. |
