Surface protective film, optical member, and electronic member |
abstract |
Provided is a surface protective film that uses a polyurethane-based resin in a pressure-sensitive adhesive layer, the surface protective filmbeing able to achieve both of excellent wettability, and low contamination property and adhesive residue reduction, and having excellent reworkability. Also provided are an optical member and an electronic member each having attached thereto such surface protective film. The surface protective film is a surface protective film, including: a backing layer; and a pressure-sensitive adhesive layer, in which: the pressure-sensitive adhesive layer includes a polyurethane-based resin; and the surface protective film has a pressure-sensitive adhesive strength for an acrylic plate of 0.5 N/25 mm or less after being attached to the acrylic plate and stored at 70°C for 1 day. The surface protective film is also a surface protective film, including: a backing layer; and a pressure-sensitive adhesive layer, in which: the pressure-sensitive adhesive layer includes a polyurethane-based resin; the polyurethane-based resin includes a polyurethane-based resin obtained by curing a composition including a polyol (A) having at least two OH groups and a polyfunctional isocyanate compound (B); and the polyfunctionalisocyanate compound (B) includes a polyfunctional aromatic isocyanate compound. |
