Abstract: PROBLEM TO BE SOLVED: To give a pattern having gloss and depth to a decorative molding and to improve weather resistance and durability, by constituting it by at least three layers of a base material layer made of low foamable thermoplastic synthetic resin, an intermediate layer containing patterned synthetic resin layer, and surface layer made of transparent synthetic resin. SOLUTION: As a base mateal layer 3, low foamable thermoplastic synthetic resin is used, and PVC resin or ABS resin is particularly preferable in view of moldability, high toughness and economy. Foaming magnification of the low foamable layer 3 is more preferable 2.0 to 3.0 times. An intermediate layer 2 is a thermoplastic synthetic resin layer having a pattern. As base resin of the layer 2, it is preferable to allow the layer 2 to be transparent or translucent by using transparent resin. Of them, PMMMA resin is satisfactory. As a surface layer 1, transparent synthetic resin is used.
