Document Type and Number:
WIPO Patent Application WO/2020/241725
Kind Code:
A1
Abstract:
The present invention provides a laminated body that has high surface hardness and good scratch resistance, reduces wrinkles of a hardening film during thermoforming, and is suitable as a protection plate for thermoforming. A laminated body (17X) of the present invention comprises: a thermoplastic resin layer (16X) having a laminate structure in which a first resin layer (21) having a composition different from that of a second resin layer (31) is laminated on at least one surface of the second resin layer (31); and a hardening film (41) laminated on the first resin layer (21) of the thermoplastic resin layer (16X). The laminated body (17X) has a Z value of 10 to 75 defined by the following formula (1). Z = 93.1 – 11 × X + 1.5 × Y…(1) (wherein X represents a composite elastic modulus (GPa) of the hardening film at 23°C, and Y represents a thickness (μm) of the hardening film.)
