Title:
THERMOPLASTIC RESIN LAMINATE
Document Type and Number:
WIPO Patent Application WO/2011/162183
Kind Code:
A1
Abstract:
Disclosed is a thermoplastic resin laminate used in transparent substrate materials and transparent protective materials and that has excellent transparency, low birefringence, and excellent formability. Specifically disclosed is a composite resin laminate wherein a vinyl copolymer resin (A) layer is laminated to one surface or both surfaces of a methacrylic resin (B) layer. The vinyl copolymer resin (A) includes a (meth)acrylate constituent unit (a) shown in a specific formula and an aliphatic vinyl constituent unit (b) shown in a specific formula, with the total ratio of the (meth)acrylate constituent unit (a) and the aliphatic vinyl constituent unit (b) being 90-100 mol% of the total amount of all constituent units of the vinyl copolymer resin (A). The molar ratio of the (meth)acrylate constituent unit (a) and the aliphatic vinyl constituent unit (b) in the vinyl copolymer resin (A) is 65:35 to 85:15. The thermoplastic resin laminate is characterized by 90 mol% or more of the total constituent units of the methacrylic resin (B) being constituent units that do not have a benzene ring.
