<p>PROBLEM TO BE SOLVED: To enhance the weatherability and surface hardness of a polyester resin sheet and to provide a laminated sheet high in interlaminar strength without damaging the excellent impact-resistant strength originally possessed by the polyester resin sheet. SOLUTION: A laminated sheet is obtained by arranging a resin layer comprising a mixture of polymethyl methacrylate and a phenoxy resin and a resin layer comprising polymethyl methacrylate containing an ultraviolet absorber on the single surface or both surfaces of a base material of a polyester polymer based on polyethylene terephthalate in this order by integral co-extrusion.</p> |
