た。2. Description of the Related Art In general, decorative materials such as plastic decorative plywood are made of wood or steel plate such as plywood as a base material, and a printed or colored resin sheet (decorative sheet) is applied thereto. Attached ones are often used. The laminated resin sheet usually has a transparent surface layer, a printed and / or colored printed layer and a base layer,
Each of these layers is laminated via an adhesive layer as needed. As a material for this decorative sheet, a vinyl chloride resin has been widely used because of its superior design and workability, but in recent years, chloride generated during disposal after incineration after use has been used. Due to problems such as treatment of hydrogen gas and selection of furnace materials for incinerators to be used, decorative sheets made of polyolefin-based resins have been used. However, a decorative sheet using a polyolefin-based resin has a large phenomenon of whitening at the time of bending, and has a problem in that, for example, in processing such as V-cut and wrapping, the appearance due to bending and whitening is reduced, and the commercial value is impaired.

(3) Bending whitening resistance: The degree of whitening of the bent portion when the film was bent at 180 ° in an atmosphere of 0 ° C. was visually judged according to the following criteria. ：: No whitening △: Slightly whitening ×: Significant whitening (4) Peelability: One side of each film of Examples and Comparative Examples was coated with an emulsion two-part curable adhesive, and plywood was used as a base material on one side To make a cosmetic material. Using this decorative material, peel the film from the plywood,
The state of peeling at that time was visually determined based on the following criteria. ：: Cleanly peeled off plywood △: Slightly cohesive breakage of film and remained on plywood ×: Cohesive breakage of film and remained on plywood
