PROCESS FOR PRODUCING FILM WITH RUGGED PATTERN AND PRODUCTION APPARATUS THEREFOR

摘要

A process for producing a film with rugged pattern excelling in the uniformity of rugged pattern; and a production apparatus therefor. There is provided a process for producing a film with rugged pattern, comprising forming a rugged pattern on a transparent resin film by means of an emboss roll with rugged surface, characterized in that the emboss roll is made of quartz, and that an ultraviolet hardening resin composition is introduced in an interstice of the emboss roll and the transparent resin film wound round the emboss roll and irradiated with ultraviolet rays emitted by an ultraviolet irradiation unit from the interior of a cavity roll supported by multiple supporting members toward the roll surface to thereby form an ultraviolet hardened resin layer with rugged surface, this ultraviolet hardened resin layer together with the transparent resin film detached from the emboss roll.
