US 2013/0280489 A1 · LAMINATED STRUCTURE AND MANUFACTURING METHOD OF PROCESSED PRODUCT

Abstract

The present invention relates to a laminated structure having a molded body that has a fine concavo-convex structure on a surface thereof and a protection film that is allowed to come into contact with the surface of the molded body on the side of the fine concavo-convex structure, in which the average interval between convexes of the fine concavo-convex structure is equal to or shorter than a wavelength of visible light, and adhesion strength of the protection film when the protection film is attached to the fine concavo-convex structure is 0.1 to 1.7 N/25 mm. According to the present invention, a laminated structure for manufacturing a processed product which can be easily processed without causing the protection film to be easily detached and has little residual adhesive can be provided.
