Document Type and Number:
WIPO Patent Application WO/2019/208632
Kind Code:
A1
Abstract:
This decorative sheet (20) comprises: a substrate layer (1); a pattern layer (2) that is provided on the surface (1a) side of the substrate layer (1); and a thermoplastic resin layer (3) that is provided on the surface (2a) side of the pattern layer (2). When a test piece with a width of 8 mm is prepared from the decorative sheet (20) and the storage modulus is measured for the prepared test piece with an initial chuck distance of 10.77 mm, at a start temperature of 30°C, an end temperature of 150°C, a temperature increase rate of 5°C/min, and a measurement frequency of 1.0 Hz, the ratio of the difference between a first storage modulus when environmental temperature is 30°C and a second storage modulus when the decorative sheet (20) changes from a glassy region to a transition region to the difference between the second storage modulus and a third storage modulus when the decorative sheet (20) changes from the transition region to a rubbery flat region becomes 3.5 times or less.
