Abstract
The invention provides a transparent resin film that has a smooth surface on a side to be laminated on a substrate to prevent entering of air bubbles when bonded to a substrate and has a pattern of protrusions and depressions on a side opposite to the side to be laminated on a substrate to provide high design quality, a method for producing the transparent resin film, and a decorative material. The invention relates to a transparent resin film to be laminated on a substrate including a picture layer, the transparent resin film having a pattern of protrusions and depressions with a maximum height Rz of 20 μm or higher and 200 μm or lower on a side opposite to a side to be laminated on the substrate, the transparent resin film having a maximum height Rz of 20 μm or lower on the side to be laminated on the substrate.
