FILM FOR PROTECTING COATING

摘要

PROBLEM TO BE SOLVED: To provide a film for protecting a coating which is hardly released from the coating, even when it is stored outside in a winter season in a state that it is temporarily adhered to the coating and exposed to a low temperature, and hardly causes the adhesive remaining on the surface of the coating when peeled off, even if the film is exposed to sunlight or the like. SOLUTION: The film for protecting a coating comprises a polyolefin substrate and, laminated thereon, a pressure-sensitive adhesive layer composed of a pressure-sensitive adhesive composition comprised of a rubber-based resin component and a tackifier resin, wherein the polyolefin substrate contains a weather-proofing agent and exhibits an ultraviolet transmittance of at most 10% within the wavelength range of 190-370 nm, the rubber-based resin component is a styrene-based elastomer having a main skeleton composed of a specific block copolymer, the pressure-sensitive adhesive layer has a shear storage modulus of at most 3×107Pa at -30°C at a frequency of 10 Hz and the shear storage modulus at 10 Hz is within the range from 5×104to 5×106Pa at 23°C.
