1. A curable resin composition comprising an alkylene oxide-modified dipentaerythritol (meth)acrylate having a structure represented by the following general formulae (I) and (II), and, as dispersed therein, surface-untreated inorganic microparticles having a mean particle size of from 1 to 150 nm, wherein a ratio of the inorganic microparticles in a total weight of these is from 10 to 45% by weight and a content of a solvent is 1% by weight or less: wherein in the general formula (I), R represents a substituent represented by the general formula (II), AO indicates one kind or two or more kinds selected from alkylene oxide units represented by —CH2CH2O—, —CH2CH(CH3)O—, —CH2CH2CH2CH2O—, and —CH2CH(C2H5)O—, L indicating a mean degree of polymerization of added alkylene oxide chains is 0<L≦5, a mean value of m is more than 0 and 5 or less, a mean addition molar number L×m of alkylene oxides is 0<L×m≦5, n is 1 or 2, a mean value of o is 0 or more and 6 or less, and a total value of m, n and o is 6; and in the general formula (II), R2 represents a hydrogen atom or a methyl group. |
