Abstract

A process for producing a sheet-form molded article having a support (2) and a resin layer which is provided in one of the main face sides of the support (2) and has peaks and valleys on the face opposite to the side of the support (2), comprising the resin layer-forming step, wherein a coating layer containing a radiation-curable resin composition containing a radiation-curable resin is brought into contact with a mold provided with a surface having peaks and valleys in the state where the coating layer is superimposed on the support to thereby transfer the peaks and valleys on the surface of the mold having the peaks and valleys onto the coating layer, and then the radiation-curable resin contained in the coating layer is cured to thereby convert the coating layer into the resin layer, characterized in that the radiation-curable resin in the uncured state contains at least one monomer A selected from the group consisting of a monofunctional vinyl monomer and a monofunctional (meth)acryl monomer and at least one member selected from the group consisting of a polyfunctional (meth)acryl monomer and a polyfunctional (meth)acryl oligomer and the viscosity of the radiation-curable resin composition at 25oC is from 3 to 100 mPa.s.
