Process for producing resin moldings having a concave-convex pattern on the surface

摘要

A process for producing a resin molding having a concave-convex pattern on the surface includes the steps of providing an original die having a concave-convex pattern on the surface and a substrate having a flat surface, thereby counterposing the concave-convex pattern surface and the flat surface to each other through a spacer and forming a cell with a cavity formed by the original die, the substrate and the spacer; making an internal pressure of the cell cavity lower than an external pressure thereof, thereby filling at least one of a liquid polymerizable component and a liquid resin into the cavity due to a pressure difference between the external pressure and the internal pressure; curing at least one of the polymerizable component and the liquid resin in the cavity, thereby making a replica; and peeling the original die from the replica, thereby obtaining a resin molding.
