(57) [Summary] (Modified) [PROBLEMS] To provide a substituted allyl ester of an unsaturated fatty acid that can be used as a reactive component of a composition that reacts with active energy rays such as light and electron rays. A novel acrylic acid ester represented by the following general formula (1) in which the ester residue is an allyl group having two or more substituents. (In the formula (1), R 1 is a hydrogen atom, a substitutable alkyl group or a halogen atom, R 2 to R 6 may be the same or different from each other, and a hydrogen atom, a halogen atom, a nitro group, a cyano group, a substituent An alkyl group, a substituted alkenyl group, a substituted alkadienyl group, a substituted vinyl group, R 2 to R At least two of 6 are substituents other than hydrogen atoms. R 2 and R 5 , R 4 and R 6 , and R 5 and R 6 may independently form a ring. Each group has 12 or less carbon atoms. ) |
