This invention is a resin composition for coating agents containing the compound which can improve scratch resistance, such as a hard-coat agent, and the said compound. The silicon compound of the present application is a silicon compound (a) represented by the formula (I) in the specification, wherein R 1 is alkylene having 3 or 4 carbon atoms, and X is a formula (II) to ( (Meth) is a group selected from the group consisting of III), n is an integer of 0 or 1, and Y is selected from the group consisting of formulas (IV) to (VI) in the specification One group having an acrylate group, R 2 is hydrogen or a methyl group. When the silicon compound (a) is used together with a curable resin, the scratch resistance considered to be due to stress relaxation can be remarkably improved. |
