[PROBLEMS] To provide a surface protective film for an optical member, etc., which is compatible with both high-speed peelability and compatibility, which are contradictory properties, excellent in low-speed adhesive force, and excellent in antistatic performance. A solvent-type re-peeling pressure-sensitive adhesive composition capable of forming a layer is found, and a re-peeling pressure-sensitive adhesive product having good characteristics is provided. A solvent-type re-peeling pressure-sensitive adhesive composition capable of forming a pressure-sensitive adhesive layer having excellent antistatic ability, the pressure-sensitive adhesive layer having a thickness of 20 μm obtained from the solvent-type re-peeling pressure-sensitive adhesive composition Was produced on a polyethylene terephthalate film substrate having a thickness of 38 μm, and when the adhesive strength of this adhesive product was measured at 180 ° to an acrylic plate at 23 ° C. and relative humidity 65%, 30 m / min. The value obtained by dividing the adhesive force in high-speed peeling by the adhesive force in low-speed peeling at 0.3 m / min is 18.0 or less, and the surface resistivity of the pressure-sensitive adhesive layer is 1.6 N / 25 mm or less at high-speed peeling. Less than 10 13 Ω. [Selection figure] None |
