Headrests, consoles, meter covers, door trims, etc. are used by forming a polyurethane foam layer between a skin material made of vinyl chloride resin and a base material. In this polyurethane foam layer, a mixed solution of an isocyanate liquid and a polyol liquid is press-fitted between the skin material and the base material,
Although it is formed through steps such as foaming and curing, at this time, if there is a pinhole in a part of the vinyl chloride resin that is the skin material, the problem that the mixed solution that has been press-fitted leaks, and therefore the skin material There is a problem that a void is formed between the base material and a good product cannot be obtained.

The vinyl chloride-based copolymer used in the present invention is a copolymer of a vinyl chloride monomer and a monomer other than vinyl chloride. When a vinyl chloride homopolymer is used, almost no pinhole blocking effect is observed. As a monomer other than vinyl chloride, for example, ethylene, propylene, vinyl acetate, a mixture of two or more of these, and the like are preferably used, but the monomer is not limited thereto. The conversion amount of monomers other than vinyl chloride in the copolymer is usually 1 to 20 wt% with respect to the conversion amount of vinyl chloride.
