Pressure-sensitive adhesive composition and pressure-sensitive adhesive sheet using said pressure-sensitive adhesive composition

Abstract

The present invention provides a pressure-sensitive adhesive composition having an excellent pressure-sensitive adhesive force to an adherend even in a high temperature, enabling peeling with a small peel force without any adhesive residue when brought into contact with warm water during peeling, and having a pressure-sensitive adhesive force and easy peelability. The pressure-sensitive adhesive composition according to the present invention contains: an acrylic polymer containing a structural unit of an alkoxy group-containing (meth)acrylate monomer as a main component and containing, with respect to 100 parts by mass of all components of monomer structural units, 1 to 40 parts by mass of a structural unit of a polymerizable monomer having a homopolymer Tg of 0° C. or higher; and a surfactant.
