<p>PROBLEM TO BE SOLVED: To provide a screen protection base film and a screen protection sheet using the same which achieve both of an excellent design having a uniform glossy feeling and visibility in addition to antistatic properties and dent resistance.SOLUTION: A screen protection base film provided with an easily adhesive layer at least on one surface of a laminate film satisfies the following conditions (1) to (4). (1) A lamination film has a layer made from a resin A (hereinafter, called an A layer) and a layer made from a resin B (hereinafter, called a B layer) alternately stacked with a total of 250 layers or more in a thickness direction, and includes three or more thick film layers having a thickness of at least 1μm or more and 20μm or less. (2) The easily adhesive layer is composed of a composition comprising an acrylic-urethane copolymer resin, cross-linking agents of two or more kinds, a chemical compound having a polythiophene structure, and the chemical compound having an anion structure. (3) An average reflectance in wavelength bands 400 to 700 nm of the screen protection base film is 10% or more and 35% or less, brightness L(SCI) in a catoptric light is 35.0 or more and 70.0 or less, and a color differenceΔE of a film width direction 1 m is 5.0 or less. (4) The easily adhesive layer side of the screen protection base film has specific surface resistivity of 1.0×10Ω/sq. or less.</p> |
