WATER-DISPERSED PRESSURE-SENSITIVE ADHESIVE COMPOSITION AND PRESSURE-SENSITIVE ADHESIVE SHEET

Provided is a water-dispersed pressure-sensitive adhesive composition capable of forming a pressure-sensitive adhesive that combines removability and repulsion resistance at a high level. This invention provides a water-dispersed pressure-sensitive adhesive composition comprising a pressure-sensitive adhesive polymer as its base polymer and an isocyanate-based crosslinking agent. The pressure-sensitive adhesive polymer has a weight ratio GA of ethyl acetate-insoluble portion of 10 % to 50 %. The isocyanate-based crosslinking agent is contained so as to yield a weight ratio GB of 15 % to 45 % with respect to the ethyl acetate-insoluble portion of a crosslinked pressure-sensitive adhesive formed from the pressure-sensitive adhesive composition.
