ABSTRACT:
The present invention relates to a pressure-sensitive adhesive composition for a surface-protective film, the composition comprising 40% by weight or more of a hydrogenated random copolymer consisting of 1 to 50% by weight of styrene and 99 to 50% by weight of a diene hydrocarbon and 60% by weight or less of a tackifier resin and/or a softener, and when the pressure-sensitive adhesive composition of the present invention is applied to the surface-protective film, the composition is caused to exhibit excellent adhesion to adherends, not to leave stains of the adherends, nor to leaves traces thereon when the films are removed from the adherends, and can also impart excellent removability to surface-protective films.
