PROBLEM TO BE SOLVED: To produce a multilayered molded article at a low cost without generating the damage or cushioning properties caused by the collapse of a foam layer, by constituting a skin material of two or more kinds of urethane foam layers different in density and positioning low density urethane foam layer on the surface side of the molded article and positioning a high density urethane foam layer on a base material side. SOLUTION: An urethane foam layer 3 is constituted of two kinds of foam layers respectively comprising soft or semihard polyurethane foams different in density. As a backing material, a nonwoven fabric of a natural fiber or a synthetic fiber such as a polyamide fiber or a synthetic resin sheet or film is used and, as a thermoplastic resin 7, polyethylene or polypropylene is used. A skin material consists of a skin layer 2, the urethane foam layer 3 consisting of two layers different in density and a backing layer 4, and the urethane foam layer 3 is arranged so that a low density urethane foam layer 3-1 is provided on the side of the skin layer 2, and a high density urethane foam layer 3-2 is provided on the side of the backing layer 4. By this constitution, the damage of cushioning properties caused by the collapse of the foam layer is prevented and a multilayered molded article can be produced at a low cost. |
