<p><P>PROBLEM TO BE SOLVED: To provide an aqueous adhesive composition having excellent anchoring properties to a porous material having a small contact area with an adhesive, exhibiting excellent adhesiveness to an adherend with low surface polarity or with a complicated shape, and having excellent re-releasability; and to provide an aqueous adhesive using the aqueous adhesive composition. <P>SOLUTION: The aqueous adhesive composition includes: a vinyl polymer (A) having one or more selected from the group consisting of an N-alkylamide structure, a lactam structure and a morpholine structure; an ester (B) of a disproportionated rosin acid; and an aqueous medium (C). The ester (B) of disproportionated rosin acid has a structure represented by general formula (1). The aqueous adhesive containing the aqueous adhesive composition, and a pressure-sensitive adhesive sheet using the aqueous adhesive are also provided. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
