Estimating the term…
The present invention is to provide a display screen protection film that exhibits uniform in-plane ultraviolet absorption property, excellent mechanical strength, flexibility, heat resistance and optical property, and to provide a polarization plate wherein the display screen protection film is used as a polarization plate protection film. The display screen protection film obtained by stretching 1.2 to 6 times a film having a thickness of 20 to 300 μm wherein an acrylic resin layer (B1) containing no ultraviolet light absorbing agent is disposed on one surface of an acrylic resin layer (A) containing the ultraviolet light absorbing agent, and an acrylic resin layer (B2) containing no ultraviolet light absorbing agent is disposed on another surface thereof.
A display screen protection film obtained by stretching with a stretching ratio of 1.2 to 6 times a film having a thickness of 20 to 300 μm, the film having an acrylic resin layer (A) containing the ultraviolet light absorbing agent, an acrylic resin layer (B1) containing no ultraviolet light absorbing agent disposed on one surface of the acrylic resin layer (A), and an acrylic resin layer (B2) containing no ultraviolet light absorbing agent disposed on another surface of the acrylic resin layer (A).
