PROBLEM TO BE SOLVED: To provide polycarbonate for use in the window glass or sunroof of a car and the window glass of a building machine excellent in weatherability, the durability in an environmental change and a high temperature environment, abrasion resistance and hot water resistance. SOLUTION: In the bonded body of polycarbonate and a metal frame, a color layer, a primer layer and a hard coat layer are successively laminated at least on one side of polycarbonate. The primer layer is constitute of an acrylic copolymer composition (A), which contains 50 mol% or above of an alkyl methacrylate (A) and/or 1-15 mol% of a hydrooxy group-containing methacrylate (A2) at least in an amount of 70%, a polyisocyanate compound (B) wherein 5.5-50 wt% of 0.8-1.5 eqivalent of an isocyanate group per one equivalent of the hydroxy group of the hydroxy group-containing methacrylate (A2) is blocked, a curing catalyst and an ultraviolet absorber, and the hard coat layer comprises organosiloxane resin composition prepared by thermally curing colloidal silica and a hydrolyzed condensate of alkoxysilane.
