Pressure-sensitive adhesive sheet

摘要

Provided is a pressure-sensitive adhesive sheet having good unwinding property from a roll body or the like and excellent antistatic property, and suitable for a surface protective film or the like. A pressure-sensitive adhesive sheet of the present invention is a pressure-sensitive adhesive sheet including a back surface layer (A), a backing layer (B), and a pressure-sensitive adhesive layer (C), the back surface layer (A) and the pressure-sensitive adhesive layer (C) being outermost layers. The pressure-sensitive adhesive sheet has a 10-m/min unwinding force of 0.6 N/20 mm or less, and the back surface layer (A) has a surface resistance value of less than 1×10 14 ©/–¡. In preferred embodiments the pressure-sensitive adhesive layer (C) contains a polyolefin-based resin and the back surface layer (A) contains a block copolymer of a block of a polyolefin and a block of a hydrophilic polymer like a polyether.
