The present invention relates to a multilayer composition comprising a surface layer comprising a thermoplastic polymer A and a substrate layer comprising a polymeric composite material based thermoplastic (meth)acrylic matrix and a fibrous material as reinforcement. The multilayer composition is suitable for mechanical or structured parts or articles with a decorative surface aspect The present invention concerns also a manufacturing process for multilayer mechanical or structured parts or articles and three-dimensional mechanical or structured parts.

An object of the present invention is to provide a laminated member for decoration that can be molded into a complicated shape and has a superior hardcoating property. The present invention relates to a laminated member for decoration having a protective film, a coating layer and a resin substrate, wherein the surface roughness Rz(a) of the adhesive layer of the protective film on the side where the coating layer is located and the surface roughness Rz(b) of the coating layer of an unheated sample formed by peeling the protective layer, the surface roughness being taken on the side opposite from the resin substrate, define Rz(b)/Rz(a)100 having a prescribed relationship; the surface roughness Rz(b) and the surface roughness Rz(bh) of the coating layer of a heated sample prepared by heating the unheated sample under a prescribed condition, the surface roughness being taken on the side opposite from the resin substrate, satisfy at least one of Formulas (2) and (3) below:
0%Rz(bh)/Rz(b)100<30%(2), and
0Rz(bh)Rz(b)<0.5 m(3);
and the unreacted (meth)acryloyl groups of the coating layer of the heated sample irradiated with a prescribed amount of active energy rays have disappeared 10 to 100% as compared with the coating layer of the unheated sample.
