PROBLEM TO BE SOLVED: To provide a repeelable water-dispersible acrylic adhesive composition, capable of forming an adhesive layer, which has excellent antistatic performance, adhesion property, re-peelability, peeling stability, resistance to a rise in adhesive force, resistance to the formation of marks on an adherend, particularly resistance to the formation of white marks (white mark resistance) occurring on the adherend under high-humidity environments, and excellent appearance properties.SOLUTION: The re-peelable water-dispersible acrylic adhesive composition contains: an acrylic emulsion polymer comprising 70-99.5 wt.% of a (meth)acrylic acid alkyl ester and 0.5-10 wt.% of a carboxyl group-containing unsaturated monomer as the monomer units; an ionic compound; and a polyether-type defoaming agent represented by the following formula (I). (I) HO-(PO)-(EO)-H. [In the formula (I), PO represents an oxypropylene group, EO represents an oxyethylene group, m1 represents an integer of 0-40, n1 represents an integer of at least 1, and the form of addition of EO or PO is random or block.]SELECTED DRAWING: None |
