Document Type and Number:

WIPO Patent Application WO/2020/116576

Kind Code:

A1

Abstract:

The present invention addresses the problem of providing a decorative laminate member that allows molding in a complex shape and has excellent hard coating performance. The present invention pertains to a decorative laminate member that has a protection film, a coating layer, and a resin base material, wherein: a surface roughness Rz(a) on the coating layer side of an adhesive layer of the protection film and a surface roughness Rz(b) on the opposite side, to the resin base material, of the coating layer of a non-heated sample from which the protection film has been peeled off, have a predetermined relationship of Rz(b)/Rz(a)×100; the surface roughness Rz(b) and a surface roughness Rz(bh) on the opposite side, to the resin base material, of the coating layer of a heated sample obtained by heating the non-heated sample in a predetermined condition, satisfy at least one of (2): 0%≤Rz(bh)/Rz(b)×100<30% and (3): 0≤Rz(bh)≤Rz(b)<0.5 μm); and 10-100% of a non-reacted (meth)acryloyl group of the coating layer of the heated sample irradiated with a predetermined amount of active energy rays has been eliminated as compared with the group of the coating layer of the non-heated sample.
