PROBLEM TO BE SOLVED: To provide a decorative sheet which has an acrylic transparent thermoplastic resin on the surface and shows a low degree of whitening by a warm water immersion test at 70°C. SOLUTION: In a manufacturing method of the decorative sheet in which a pattern is printed on the surface of a thermoplastic resin base material and an acrylic transparent thermoplastic resin is heat-laminated through an anchor agent, the thermoplastic resin base material is added with porous calcium carbonate and the temperature of the heating roll at the heat lamination is 100-140°C. The adhesive force between the anchor layer and the acrylic transparent thermoplastic resin is also improved. COPYRIGHT: (C)2009,JPO&INPIT
