ABSTRACT:
There are provided a resin film being excellent in blocking resistance, scratch resistance, transparency, water resistance and chemical resistance and a member having the resin film as an outermost layer. The resin film comprises a vinylidene fluoride (VdF) copolymer and an acrylic polymer as essential components, in which a heat of fusion of crystal derived from the VdF copolymer in the resin film is from 15 to 30 J/g when measured with a differential scanning calorimeter (DSC), and light transmittance (light transmittance at 600 nm of 50 μm thick resin film) is not less than 85%. The member has the resin film as an outermost layer.
