The pressure sensitive adhesive composition is favorably utilized for lamination of plastic molded articles, particularly molded articles of polycarbonate resins and molded articles of acrylic resins because formation of blisters, such as bubbles and liftings, is prevented. It is favorably utilized for pressure sensitive adhesive sheets for surface protection because increase of adhesive strength is small, staining of the surface of the substrate is prevented and removability is excellent. It is also favorably utilized for electric insulation tapes because corrosion resistance, creep property and solvent resistance are excellent. The pressure sensitive adhesive composition comprises as the main component thereof a specific acrylic copolymer prepared by copolymerization of a specific methyleneamine derivative of acrylamide, a specific amine derivative of acrylimide, a specific diacetone derivative of acrylamide and a specific ester of acrylic acid.

The present invention provides an alkali soluble pressure sensitive adhesive composition comprising 100 parts by weight of a polymer obtained by polymerization of carboxyl group-containing vinyl monomer as an adhesive component and 50-500 parts by weight of a nonionic surface active agent capable of endowing plasticity as a main additive component. The tack papers or the adhesive tapes using the adhesive compositions according to the invention can be readily dissolved in alkali water in the step of repulping and the reclaimed papers without adhesiveness can be prepared with them. Further, the alkali soluble pressure sensitive adhesive compositions of the present invention are excellent in moisture dependence, tack properties at low temperatures and bleeding properties at high temperatures. Especially, the compositions are improved in shearing strength by adding cross-linking agents and are improved in adhesiveness to glass by adding silane coupling agents, and so are suitable for labels and the like of beer bottles, etc.
