<P>PROBLEM TO BE SOLVED: To provide a water-dispersed pressure-sensitive adhesive composition which has moderate initial adhesiveness and moderate peeling force after adhering an adherend, and to provide an adhesive tape using the water-dispersed pressure-sensitive adhesive composition. <P>SOLUTION: The water-dispersed pressure-sensitive adhesive composition includes an acrylic polymer crosslinked product (A) which is obtained by carrying out emulsion polymerization, and a crosslinking agent (B), wherein the acrylic polymer crosslinked product (A) is obtained by carrying out the emulsion polymerization of a monomer composition which includes: 50 wt.% of an alkyl acrylate (a) having a 4-12C alkyl group; 30-45 wt.% of an alkyl methacrylate (b) having a 1-4C alkyl group; 0.5-2.5 wt.% of a functional monomer (c) which does not become involved with the crosslinking with the crosslinking agent (B); and a functional monomer (d) which becomes involved with the crosslinking with the crosslinking agent (B). <P>COPYRIGHT: (C)2012,JPO&INPIT |
