WIPO Patent Application WO/2019/198559

Kind Code:

A1

Abstract:

The present invention addresses the problem of providing a protective film which uses a resin containing a thermoplastic polyurethane, and which is suppressed in adhesive residue, while exhibiting excellent contamination resistance, impact resistance, workability, anti-glare properties and bonding characteristics. A protective film according to the present invention is provided with: a base film which is formed of a resin that contains a thermoplastic polyurethane; and an adhesive layer. This protective film is configured such that: the base film has a surface layer, in which the thermoplastic polyurethane and a curable resin composition coexist, on a second surface that is on the reverse side of a first surface; the curable resin composition contains a curable resin and at least one fluorine compound that is selected from the group consisting of fluorosilsesquioxanes and fluorosilsesquioxane polymers; and an impact resistance-imparting layer is formed on the first surface of the base film, or alternatively, the gloss value of the second surface of the base film is less than 20.
