(57) [Summary] [PROBLEMS] To reduce the time-dependent increase in adhesive force to an adherend, to easily re-peel after processing of the adherend, to contaminate the adherend at the time of re-peeling, Provided is a water-dispersible removable pressure-sensitive adhesive having no residue. SOLUTION: An acrylate monomer is 50 to 99.9% by weight, a carboxyl group-containing monomer is 0.1 to 5% by weight, and a monomer 0 to 49. 9% by weight A water-dispersible acrylate copolymer of a monomer mixture comprising a carbodiimide group-containing crosslinking agent and a carbodiimide group to carboxyl group ratio (carbodiimide group / carboxyl group) of 0 .1 to It is blended so as to be 5.0, and the removability is 500 g. / 20 mm width or less, water-dispersible pressure-sensitive adhesive for re-peeling. |
