PROBLEM TO BE SOLVED: To obtain the subject silicone capable of enabling the more rapid and more efficient photochemical hardening of a silicone release coating by including a specific structure. SOLUTION: This epoxysilicone contains a structure of the formula MDnDEm-pD*pM [M is a group of R3SiO1/2 or R2ESiO1/2; R is an about 1-30C monovalent alkyl hydrocarbon, an about 2-30C monovalent alkenyl hydrocarbon, or the like; E is an epoxide-functional (substituted) hydrocarbon; D is a group of R2SiO2/2; DE is a group of RESiO2/2; D* is a reaction product of DE with a compound selected from a compound of the formula R'COOH, and the like; R' is a photosensitive naphthyl; (n+m+p) is about 10-2,000]. The silicone is obtained by reacting the compound of the formula MDnDEmM with a compound (e.g. 1-naphthoic acid) selected from the compound of the formula R'COOH, and the like.
