Abstract
A coating agent comprising 50 to 99 parts by weight of a monomer or monomer mixture (M) composed of 50 to 100% by weight of a polyfunctional (meth)acrylate monomer (m-1) having two or more (meth)acryloyloxy groups and 0 to 50% by weight of a monofunctional (meth)acrylate monomer (m-2), and 1 to 50 parts by weight of colloidal silica, wherein the colloidal silica contains colloidal silica in a narrow and long form having an average diameter of 5 to 20 nm and an average length of 40 to 300 nm in an amount of 5 to 100% by weight based on the total colloidal silica weight; and a resin molded article having a coated layer obtained by hardening this coating agent, are disclosed. This colloidal silica-containing coating agent is excellent in appearance, hardness, abrasion resistance, weather resistance, adhesion with a substrate, no need of a solvent, and the like.
