Abstract
Provided is a liquid curable resin composition which can produce transparent cured products with a high refractive index, high hardness, and superior abrasion resistance, and which can be suitably used as a coating material. The liquid curable resin composition comprises: (A) a poly-functional (meth)acrylic compound having at least three (meth) acryloyl groups in the molecule; (B) a reaction product obtained by the reaction of a compound having a polymerizable unsaturated group and alkoxysilyl group in the molecule and particles metal oxide, the metals being preferably selected from the group consisting of zirconium, antimony, zinc, tin, cerium, and titanium; and (C) a radiation polymerization initiator.
