PURPOSE: Provided is a redetachable, aqueous, acrylic, pressure sensitive adhesive composition which shows improved processability as well as the same adhesion and redetachment as that of existing adhesive. CONSTITUTION: The composition comprises 50-65 wt% of adhesive monomer, 0.5-5 wt% of monomer having carboxyl group, and 0.5-5 wt% of monomer having hydroxyl group. Also, the composition comprises 50-65 wt% of adhesive monomer, 0.5 wt% of monomer having carboxyl group, 0.5-5 wt% of monomer having hydroxyl group, 0.01-1 wt% of pH buffer, 0.1-5 wt% of heat initiator, 0.1-5 wt% of nonionic emulsifier, 0.5-2 wt% of anionic emulsifier, 0.1-1.0 wt% of aqueous ammonia, and 30-40 wt% of water. The adhesive monomer is selected from the group consisting of 2-ethylhexyl acrylate, butyl acrylate, octyl acrylate, and isobutyl acrylate.
