An object of the present invention is to provide a coating agent capable of forming a layer having excellent adhesion to a plastic substrate and having transparency and high refractive index. The coating agent of the present invention is a formula (I) [Wherein, A represents a phenyl group or a naphthyl group which may have an electron donating group as a substituent. Z is a carbon atom or a silicon atom, R 2 is a hydrogen atom, a hydroxyl group, a straight or branched alkyl group, a straight or branched alkoxy group, a cyclic alkyl group, or a cyclic alkoxy group, X is a single bond; Oxygen atom, sulfur atom, selenium atom, -NR-, divalent aliphatic cyclic group, arylene group, alkylene group which may contain an amide structure or urethane structure; A divalent aliphatic ring group; Or an arylene group, Y is a polymerizable functional group, n is an integer of 2 or 3, m is an integer of 1 or 2, l is an integer of 0 or 1, n + m + l = 4. When n is an integer of 2 or 3, A may be the same or different.] It contains the compound represented by. |
