  • Scratch-resistant polycarbonate resin laminate
    Patent number: 10239297
    Abstract: The present invention aims to provide a multi-layer sheet and a multi-layer film, each ensuring not only high transparency but also scratch resistance and being easy to print and thermoform. The above aim was achieved by a multi-layer sheet and a multi-layer film, each being a laminate which comprises a polycarbonate-based resin layer as a substrate and has a thermoplastic acrylic resin layer containing silicon dioxide particles as an outermost layer on one or both surfaces of the substrate, wherein the silicon dioxide particles have an average particle size of 0.1 to 2 ?m, and wherein the content of the silicon dioxide particles is 0.1% to 1% by weight, relative to the total weight of the thermoplastic acrylic resin layer.
