PROBLEM TO BE SOLVED: To obtain the subject composition capable of providing the surface of e.g. a plastic molded product, coated product with a cured coating film of excellent scratch resistance, abrasion resistance, adhesiveness to substrate and appearance, enabling such processing as printing or embossing on the coating film therefrom prior to active energy ray irradiation thereon because it is formable just after evaporation of the solvent to dryness, and also moldable after irradiated with active energy rays. SOLUTION: This liquid curable resin composition comprises (A) a multifunctional (meth)acrylic compound containing at least three (meth)acryloyl groups in the molecule, (B) a reaction product from silica particles and an alkoxysilane compound having polymerizable unsaturated group, urethane linkage group and organic group of the formula (X is NH, O or S; Y is an oxygen or sulfur atom; with the proviso that when X is O, Y is a sulfur atom), (C) a radiation-curable acrylic resin with a Tg of >=50 deg.C, a reaction product from (a) a carboxyl-contg. acrylic resin and (b) a compound having both epoxy group and unsaturated bond in the molecule, and (D) a radiation polymerization initiator.
