Abstract:

The present invention provides: a transparent resin film with which it is possible to prevent the occurrence of air bubbles when said film is adhered to a substrate since the surface on the side of said film to be laminated upon the substrate is extremely smooth, said film making it possible to achieve improved design as a result of a configuration of recesses and projections on the reverse side from the side laminated upon the substrate; a production method for said transparent resin film; and a decorative material using said transparent resin film. The present invention relates to a transparent resin film that is laminated upon a substrate having a pattern layer, said film characterized by having a configuration of recesses and projections in which the maximum height Rz(1) as defined in JIS B 0601 (2001) is 20 μm to 200 μm inclusive on the reverse side from the side laminated upon the substrate, and the maximum height Rz(2) as defined in JIS B 0601 (2001) on the side laminated upon the substrate is 20 μm or less.
