<p>PROBLEM TO BE SOLVED: To provide a water dispersion type adhesive composition capable of forming an adhesive compound having both removability and repulsion resistance at a high level.SOLUTION: A water dispersion type adhesive composition 21 or 22 includes an adhesive polymer as a base polymer, and an isocyanate-based crosslinking agent. In the adhesive polymer, the weight ratio Gof an ethyl acetate insoluble matter is 10-50%. The isocyanate-based crosslinking agent is composed so that the weight ratio Gof the ethyl acetate insoluble matter in a cross-linked adhesive compound formed of the adhesive composition satisfies 15-45%. The adhesive polymer is an acrylic polymer, and has a glass transition temperature of -60°C or lower.</p> |
