Abstract: Embodiments of the invention relate to an actinic-ray-curable resin composition which includes 100 parts by mass of a polyfunctional (meth)acrylate; 0.2-4 parts by mass of a compound having an alkoxysilyl group and a (meth)acryloyl group; 0.05-3 parts by mass of an organic titanium; and 5-100 parts by mass of fine particles having an average particle diameter of 1-300 nm. Embodiments of the invention also relate to a layered transparent resin product which includes a hardcoat layer and a layer of a transparent resin sheet in this order from the outermost layer side, wherein the hardcoat has been formed from a coating material including 100 parts by mass of a polyfunctional (meth)acrylate; 0.2-4 parts by mass of a compound having an alkoxysilyl group and a (meth)acryloyl group; 0.05-3 parts by mass of an organic titanium; and 5-100 parts by mass of fine particles having an average particle diameter of 1-300 nm.

Abstract: Embodiments provide a coating material containing: (A) 100 parts by mass of an acrylic curable resin; (B) 5-200 parts by mass of aluminum oxide particles having an average particle size of 1-100 μm; (C) 0.1-20 parts by mass of aluminum oxide fine particles having an average particle size of 1-100 nm; and (D) 1-100 parts by mass of a compound having two or more isocyanate groups per molecule. In one embodiment, the acrylic curable resin (A) includes: (a1) a structural unit derived from a hydroxy group-containing (meth)acrylic acid ester; (a2) a structural unit derived from a vinyl aromatic compound; and (a3) a structural unit derived from a (meth)acrylic acid alkyl ester. In one embodiment, the acrylic curable resin (A) may contain, in addition to the structural units (a1) and (a2): (a3-1) a structural unit derived from methyl methacrylate; and (a3-2) a structural unit derived from an aliphatic (including alicyclic) alkyl ester having 4 or more carbon atoms of a (meth)acrylic acid.
