Abstract:
To provide a surface that can satisfy all required performances at the same time: (1) balancing of adhesive strength at a low-speed peeling region and a high-speed peeling region, (2) prevention of occurrence of adhesive residue, (3) excellent anti-static performance, and (4) rework performance.SOLUTION: Adhesive strength of an adhesive layer is 0.05-0.1 N/25 mm in a low-speed peeling region and 1.0 N/25 mm or less in a high-speed peeling region, the adhesive layer being obtained by crosslinking an adhesive composition comprising: an acrylic copolymer obtained by copolymerizing (A) a (meth)acrylic acid ester monomer having a C4-C10 alkyl group, (B) a copolymerizable monomer having a hydroxyl group, and (C) a copolymerizable monomer having a carboxyl group; (D) a tri- or more functional isocyanate compound; (E) a crosslinking retarder of a keto-enol tautomeric compound; (F) a crosslinking catalyst; (G) an antistatic agent; and (H) a polyether modified siloxane compound having an HLB value of 7-12.SELECTED DRAWING: None
