Title:
RESIN LAMINATE, DISPLAY DEVICE AND POLARIZER
Document Type and Number:
WIPO Patent Application WO/2017/208883
Kind Code:
A1
Abstract:
A resin laminate especially suitable for protection of a polarizer and having ultraviolet absorbance is provided. This resin laminate comprises at least an intermediate layer (A) and thermoplastic resin layers (B) and (C) which are present on both sides of the intermediate layer (A), wherein the intermediate layer (A) contains 10-90 mass% of a (meth)acrylic resin and 90-10 mass% of a vinylidene fluoride resin on the basis of all resins contained in the intermediate layer (A), wherein the weight average molecular weight of the (meth)acrylic resin is 100,000-300,000 and at least one of the intermediate layer (A) and the thermoplastic resin layers (B) and (C) contains at least one ultraviolet absorbent agent having an absorption maximum between 320nm and 400nm, and, if TA, TB and TC (μm) are defined as the average values of the film thickness of the intermediate layer (A) and the thermoplastic resin layers (B) and (C), respectively, and WA, WB and WC (mass%) are defined as the content of the ultraviolet absorbent agent in the intermediate layer (A) and the thermoplastic resin layers (B) and (C), respectively, then X, calculated with a specific expression, is 0.01-0.25.
