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.

Abstract: One embodiment is a cosmetic sheet having a transparent adhesive layer (A), a transparent resin film layer (B), a printed layer (C), and a resin film layer (D) in this order from the side adhered to a transparent substrate, where: the transparent resin film layer (B) as a whole has an embossed profile; the printed layer (C) contains a high-brightness pigment; the printed layer (C) as a whole has an embossed profile; and the resin film layer (D) has an embossed profile on the side facing the printed layer (C). Another embodiment is a cosmetic sheet which has a transparent resin layer (E) between the layers of (A) and (B), where this transparent resin layer (E) has an embossed profile on the side facing the transparent resin film layer (B). The adhesive layer (A) may contain prescribed amounts of an acrylic polymer (P) having a glass transition temperature between −50° C. and −25° C.; a silane coupling agent (Q) having an epoxy group; a compound (R) having two or more epoxy groups per molecule; and an organic polyvalent metal compound (S).
