Provided are a decorative resin sheet that sufficiently brings together embossing property and embossment-retaining property, and a molded resin article on which an embossment excellent in design is formed and a method of manufacturing the molded resin article. The method of manufacturing a molded resin article includes the steps of: providing a resin sheet having a mold layer containing a polyolefin-based resin as a main component, followed by formation of an embossment on the resin sheet so that the embossment is formed on a surface of the mold layer; crosslinking the mold layer on which the embossment is formed so that a 100% modulus of the resin sheet at 200&#xb0; C. becomes 0.02 MPa or more, which is measured in conformity with JIS K6251 (2004 version); placing the resultant resin sheet () in an injection molding die () so that the surface () of the mold layer faces a side from which a molten resin () is injected; injecting the molten resin () onto a side of the surface () of the mold layer in the injection molding die () to mold a molded resin article; and separating the molded resin article and the mold layer.

Decorative resin sheet, and molded resin article and process for production thereof

A cellular molded article in a mold pattern having a surface skin, which has an excellent releasing property from a metal mold as well as an excellent printing property of a design formed on a surface of the metal mold, and a producing method thereof are provided. The cellular molded article in a mold pattern having the surface skin and a producing method thereof, in which, at least a face of the surface skin material, which contacts the metal mold, is an olefin thermoplastic elastomer sheet which is composed of an olefin resin without containing a polyethylene resin as its matrix, and pre-expanded beads, which are employed for an expansion molding in a mold pattern, are pre-expanded beads of an olefin resin.
