Abstract

The invention provides a resin laminate having relatively high surface hardness and high transparency. The resin laminate has a hard resin layer and a substrate layer. The hard resin layer is formed by a curing resin composition with multi-functional(methyl)acryloyl monomers as an essential ingredient, has a three-dimensional cross-linking structure and a thickness of 25 [mu]m-250[mu]m. The substrate layer is formed by a monolayer thermoplastic resin or two or more layers of a multi-layer thermoplastic resin. An independent tensile elasticity modulus of the hard resin layer is 2.000-4,000 MPa; and a total light transmittance is over 90%. Besides, a ratio (t1 / t2) of a total thickness (t1) of the substrate layer to the thickness (t2) of the hard resin layer is 0.25-10; and a Bierbaum scratch hardness of the resin laminate is 20 kg / mm<2>-700 kg / mm<2>.

Description

technical field

[0001] The present invention relates to a resin laminate having excellent surface hardness, transparency, and moldability, and particularly to a resin laminate suitable for a display panel as a transparent multilayer sheet. Background technique

[0002] In electronic equipment such as digital cameras and mobile phones, as substrates of liquid crystal displays, etc., or as protective plates for protecting the surface of liquid crystal displays from scratches, contamination, etc., acrylic, polycarbonate, poly Laminates made of thermoplastic resins such as ethylene phthalate. These laminated resins have excellent optical properties and are less prone to cracking than glass, and thus have come to be widely used in fields where glass has been conventionally used in recent years. However, thermoplastic resins such as acrylic, polycarbonate, and polyethylene terephthalate have disadvantages in that surface hardness, abrasion resistance, and scratch resistance are i...
