## Abstract

Disclosed herein are a di-(1-vinylimidazole) metal phthalocyanine compound in which 1-vinylimidazoles as ligands are included in a phthalocyanine having a metal, a composition comprising the same and a preparation method thereof. The di-(1-vinylimidazole) metal phthalocyanine compound has an excellent UV blocking effect together with low surface resistance and is prepared but by charging a powder phase with nitrogen, not by dissolving raw materials in an organic solvent as in the prior art.

## Claims
