Patent ID: 8623161

Claim:
A process for producing an article having a fine concavo-convex structure on its surface, which comprises the following steps (I), (II) and (V): (I) a step of forming an interlayer (A) on the surface of a substrate film; (II) a step of forming a concavo-convex layer (B) having a fine concavo-convex structure on its surface, on the surface of the interlayer (A) by imprinting technology; and (V) a step of separating a laminate comprising the interlayer (A) and the concavo-convex layer (B) from the substrate film and then laminating the laminate to the surface of a transparent substrate so that the interlayer (A) faces the transparent substrate side, wherein the interlayer (A) and the transparent substrate contact each other directly or through an adhesive layer, wherein when the interlayer (A) and the transparent substrate contact each other through an adhesive layer, the adhesive layer contacts a surface of the interlayer (A) which is opposite to the surface of the interlayer (A) on which the concavo-convex layer (B) is formed.
