An acrylic adhesive composition and an adhesive product containing the composition are provided to enhance initial adhesive strength and adhesion maintenance to allow the composition to be detached by using water after use. An acrylic adhesive composition comprises 100 parts by weight of an acrylic adhesive resin; 5-30 parts by weight of a petroleum-based tackifier; and 15-40 parts by weight of a water expandable filler. Preferably the acrylic adhesive resin is an aqueous acrylic adhesive resin or an oily acrylic adhesive resin; the petroleum-based tackifier is a polymer polymerized from a vinyl monomer containing a C3-C12 (meth)acryloyl group and has a viscosity of 1,000-80,000 and a weight average molecular weight of 500-50,000; and the water expandable filler is at least one selected from poly(acrylic acid) resin, poly(methacrylic acid) resin, starch resin, cellulose resin, poly(vinyl alcohol) resin and polyoxyethylene resin and has an average particle size of 6-32 micrometers. |
