RE-RELEASABLE AQUEOUS ADHESIVE COMPOSITION

PROBLEM TO BE SOLVED : To provide a re-releasable aqueous adhesive composition which shows little increase in adhesive strength over time, is excellent in antifouling property in terms of preventing staining such as adhesive deposit or marks on an adherend when re-released and is excellent in mechanical stability as an aqueous adhesive composition. SOLUTION : The re-releasable aqueous adhesive composition comprises an emulsion [A] and a crosslinking agent [B], wherein the emulsion [A] is obtained through emulsion polymerization of a monomer mixture containing 50-99.7 wt.% alkyl (meth)acrylate (a1) containing a 4-12C alkyl group, 0.1-20 wt.% unsaturated monomer (a2) containing a carboxy group, 0.1-20 wt.% polyfunctional unsaturated monomer (a3), 0.1-10 wt.% unsaturated monomer (a4) containing a carbonyl group and 0-49.8 wt.% other unsaturated monomer in the presence of a reactive emulsifier.
