PROBLEM TO BE SOLVED: To provide a decorative sheet which, since it contains no solvent and also no formaldehyde and no phenol, does not cause sick house syndromes and does not adversely affect the air pollution and further is friendly to the environment. SOLUTION: A resin composition for a decorative sheet, which contains a crystalline oligomer having curability and being solid at ordinary temperature and an unsaturated polyester, is coated on a pattern paper for a decorative sheet; a curing agent solution is coated on the rear surface of the sheet; and the resultant laminate is hot-pressed together with a core material to form an integrated article. The formulation ratio of the unsaturated polyester is 5-400 pts.wt. based on 100 pts.wt. of the crystalline oligomer. In order to improve surface appearance and surface physical properties, the resin composition for the decorative sheet may be incorporated with a diallyl phthalate prepolymer. The formulation ratio of the diallyl phthalate prepolymer is 1-100 pts.wt. based on 100 pts.wt. of the solid content of the crystalline compound. COPYRIGHT: (C)2009,JPO&INPIT
