A composition of polyvinyl for powder molding may include a polyvinyl chloride (A), a polyvinyl chloride (B), a plasticizer, and an alkyl phosphate. The polyvinyl chloride (A) may have an average particle diameter of 50 &#x3bc;m to 500 &#x3bc;m, and the polyvinyl chloride (B) may have an average particle diameter of 0.01 &#x3bc;m or more and less than 50 &#x3bc;m. An average polymerization degree of the polyvinyl chloride (A) may be 1350 or more, the alkyl phosphate may comprise a mono-alkyl phosphate, and the number of carbon atoms of an alkyl group in the alkyl phosphate may be 5 or more.

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.
