Document Type and Number:

WIPO Patent Application WO/2014/125976

Kind Code:

A1

Abstract:

Provided is a resin laminate which has high surface hardness, while having high transparency. A resin laminate which comprises: a hard resin layer which is formed from a curable resin composition containing, as an essential component, a polyfunctional (meth)acrylic monomer, and which has a three-dimensional crosslinked structure, while having a thickness of from 25 μm to 250 μm (inclusive); and a base layer which is composed of one or more layers that are formed of a thermoplastic resin. This resin laminate is characterized in that: the hard resin layer has a tensile modulus of 2,000-4,000 MPa and a total light transmittance of 90% or more by itself; the number of moles of the (meth)acryl groups of the curable resin composition per 100 g of the solid content is 0.6-0.9; and the laminate has a pencil hardness of 6H or more.
