PROBLEM TO BE SOLVED: To provide a water dispersion type acrylic tacky-adhesive agent composition for re-exfoliation, from which a tacky-adhesive layer of a tacky-adhesive sheet, that exhibits an excellent pickup property and an excellent curl adjusting property, is formed.SOLUTION: The water dispersion type acrylic tacky-adhesive agent composition for re-exfoliation contains an acrylic emulsion-based polymer, a water-insoluble crosslinking agent, an acetylene diol-based compound and an ether group-containing polysiloxane. The acrylic emulsion-based polymer is obtained by using alkyl (meth)acrylate and a carboxyl group-containing unsaturated monomer as essential starting monomers. The content of the alkyl (meth)acrylate is 70-99.5 wt.% of the total weight of the starting monomers and that of the carboxyl group-containing unsaturated monomer is 0.5-10.0 wt.% of the total weight of the starting monomers. When the content of the water-insoluble crosslinking agent is X pts. wt. on the basis of 100 pts. wt. of the acrylic emulsion-based polymer and that of the ether group-containing polysiloxane is Y pts. wt. on the basis of 100 pts. wt. of the acrylic emulsion-based polymer, the value (A), which is calculated by using the expression (1):(A)=X+(Y×3), is 3 or larger. |
