PEROXYCINNAMATE DERIVATIVE AND POLYMERIZABLE COMPOSITION CONTAINING SAID COMPOUND

The peroxycinnamate derivative according to the present invention is represented by general formula (1) (in formula (1), n represents an integer from 1 to 3; each R1 independently represents a substituent represented by general formula (2): R-X-, a nitro group, or a cyano group; X represents an oxygen atom or sulfur atom; and R represents a hydrocarbon group having 1 to 6 carbons, which may have,in the carbon skeleton, at least any one of an ether bond, thioether bond, and a hydroxyl group at the terminal. Or, R1 represents a hydrocarbon group that forms a 5- or 6-membered ring as provided bytwo adjacent R-X- substituents represented by general formula (2). R2 represents a hydrogen atom or methyl group; R3 and R4 each independently represent a methyl group or ethyl group; and R5 represents an aliphatic hydrocarbon group having 1 to 5 carbons, or represents an aromatic hydrocarbon group having 6 to 9 carbons, which may have an alkyl group.). 本发明提供一种通式(1)所表示的过氧化肉桂酸酯衍生物，该过氧化肉桂酸酯衍生物同时具有能够有效地吸收由灯发出的波长为365nm等的光而产生自
