Title:

RESIN SHEET FOR MOLDING AND MOLDED ARTICLE USING SAME

Document Type and Number:

WIPO Patent Application WO/2021/029266

Kind Code:

A1

Abstract:

The present invention provides a resin sheet for molding that has a high-hardness resin layer that includes a high-hardness resin on at least one surface of a base material layer that includes a polycarbonate resin (a1), the high-hardness resin layer having a hardcoat layer or a hardcoat anti-glare layer layered on at least one side thereof. The glass transition points of the polycarbonate resin (a1) and the high-hardness resin satisfy the following relationship: -10°C≤(the glass transition point of the high-hardness resin)-(the glass transition point of the polycarbonate resin (a1))≤40°C. The in-plane retardation of the resin sheet as measured at a wavelength of 543 nm is at least 4,000 nm. A resin film (X) that has an in-plane retardation of no more than 50 nm as measured at a wavelength of 543 nm is stuck to one side of the resin sheet by means of an adhesive layer that includes an adhesive.
