Document Type and Number:
WIPO Patent Application WO/2018/147357
Kind Code:
A1
Abstract:
Provided is a multilayer sheet which is able to be produced at low cost, while having excellent weather resistance, excellent wet heat resistance and good interlayer adhesion. The present invention provides a multilayer sheet wherein: a first resin layer is formed from a polycarbonate resin, wherein 90% by mass or more of the total mass of the polycarbonate resin is a polycarbonate block, or a polycarbonate resin composition that contains this polycarbonate resin; a second resin layer is formed from an acrylic resin or an acrylic resin composition wherein 40% by mass or more of all resin components is an acrylic resin; a third resin layer is formed from a polyvinylidene fluoride resin composition wherein 50-99% by mass of all resin components is a polyvinylidene fluoride resin and 1-50% by mass of all resin components is a methacrylic acid ester resin; and the first resin layer, the second resin layer and the third resin layer are arranged in this order to constitute a multilayer structure.
