PURPOSE: To provide a vinyl chloride resin film which constitutes the surface layer of a door for a system kitchen, a furniture, a closet and a face washing basin by formulating specific amounts of 2 kinds of acrylic resins different in their molecular structures and a plasticizer. CONSTITUTION: This film comprilses (A) 100 pts.wt. of PVC, (B) less than 30 pts.wt. of a methyl methacrylate/acrylic acid copolymer of formual I (R is an alkyl), anα-methyl-styrene/acrylonitrile copolymer or a methyl methacrylate/ maleimide copolymer, (C) less than 20 pts.wt. of a methyl methacrylate/alkyl acrylate copolymer of formula II, and (D) less than 20 pts.wt., particularly 5-12 pts.wt. of a plasticizer. The film has higher Vicat-softening temperature, heat distortion temperature and flex temperature than those of PVC and the shrinkage of the film can be suppressed when it is laminated on a curved-face substrate, by stretching it with a curved face laminating machine.
