摘要： The present invention can provide a transparent resin film that has a pattern of protrusions and depressions to have excellent design properties, and can suppress yellowing even when irradiated with electron beams in its production to prevent impairment of design properties, while imparting weather resistance. The present invention relates to a transparent resin film for use in protection of a picture layer laminated on one side of a substrate, the transparent resin film including at least: a transparent resin film; and a transparent surface protective layer, laminated in the stated order, the transparent resin film having a pattern of protrusions and depressions on a side opposite to a side where the picture layer is to be laminated, the transparent surface protective layer containing an ionizing radiation curable resin, at least one of the transparent resin layer or the transparent surface protective layer containing a triazine UV absorber.
