透明樹脂積層体並びにそれを用いた透明基板材料及び透明保護材料
Document Type and Number:
Japanese Patent JP7265960
Kind Code:
B2
Abstract:
To provide a resin laminate having excellent thermoformability at a low temperature and having a good appearance that suppresses an occurrence of interference fringes.SOLUTION: There is provided a resin laminate, including: a layer containing a thermoplastic resin (B) on at least one surface of a layer containing polycarbonate resin (A); and a hard coat layer on at least one surface of a layer containing thermoplastic resin (B). The polycarbonate resin (A) has a glass transition temperature higher than 140°C and 170°C or lower. In the thermoplastic resin (B), a content of premethacrylic resin (C) is 5 to 70 parts by mass, and a content of styrene copolymer (D) is 95 to 30 parts by mass based on a total of 100 parts by mass of a content of the methacrylic resin (C) and the styrene copolymer (D), and the methacrylic resin (C) contains 80 mol% or more of structural units derived from methacrylic ester monomer, and the styrene copolymer (D) is a copolymer containing 68 to 84% by mass of a vinyl aromatic monomer unit (d1) and 16 to 32% by mass of a cyclic acid anhydride monomer unit (d2).SELECTED DRAWING: None
