Abstract
A derivative of naphthalocyanine containing a perfluoroalkyl group and having a particular structure for ensuring excellent weather-proof properties, extremely high solubility in various solvents and capability of forming a film, and an optical recording medium prepared by using the derivative and capable of recording while using a focused beam of a semiconductor laser or the like. The derivative of naphthalocyanine containing a perfluoroalkyl group may be prepared by reacting a perfluoroalkanoyl peroxide having a particular structure with a naphthalocyanine.
