摘要：
The present invention provides an acrylic water-dispersible pressure-sensitive adhesive composition that can prepare a removable adhesive layer having low contamination of an adherent. The acrylic water-dispersible pressure-sensitive removable adhesive composition according to the present invention comprises an acrylic emulsion polymer (A) comprising an alkyl (meth)acrylate ester and a carboxyl group-containing unsaturated monomer as essential raw material constitutive monomers and prepared by polymerization with a reactive surfactant containing no oxyalkylene group.
