DECORATIVE SHEET, AND METHOD FOR PRODUCING DECORATIVE SHEET
To provide a decorative sheet excellent in fire-safety and constructability, and a method for producing the decorative sheet.SOLUTION: A decorative sheet 1 is provided that comprises a substrate film 10 and a pressure-sensitive layer 20 provided on at least one side of the substrate film 10. The substrate film 10 includes antimony trioxide, the pressure-sensitive layer 20 includes a pressure-sensitive and a bromine-based flame retardant and includes no antimony trioxide. A laminate, as a test specimen, is prepared which includes a gypsum board having base paper on both surfaces thereof and a decorative sheet 1 stacked on a side to which radiation heat is applied, of the gypsum board. The test piece exhibits a total heat generation amount of 7.2MJ/mor less in the following heat generation test for 20 minutes. The test piece exhibits an initial tack strength of 5 N/25 mm or more in 5°C environment and 15 N/25 mm or more in 23°C and 50%RH environment in the following initial tack strength test. The test piece further exhibits constant load property of 5 mm or less in the following constant load test.SELECTED DRAWING: Figure 1
