Classification: CPC C  B | IPC B  C

Claim 1:
2. A laminate in which a surface of a support material is covered by a thermoplastic resin layer having a thickness of from 30 to 300 μm,
wherein the thermoplastic resin layer is formed by melting and mixing/kneading an acrylic resin composition at a temperature of about 250° C.,
wherein the acrylic resin composition comprises, with respect to 100 parts by mass of an acrylic resin, from 1 to 5 parts by mass of a triazine-based UV absorber consisting of 2-(4,6-diphenyl-1,3,5-triazin-2-yl)-5-[2-(2-ethylhexanoyloxy)ethoxy]phenol,
wherein the acrylic resin consists of methyl methacrylate and optionally butyl methacrylate as monomer components, a blending amount of methyl methacrylate being 80 wt % or more, and a blending amount of butyl methacrylate being 20 wt % or less,
wherein the acrylic resin has a glass transition temperature of from 82° C. to 105° C., and
wherein the molecular weight of the acrylic resin is 87,000 to 119,000 in terms of mass average molecular weight.
