<P>PROBLEM TO BE SOLVED: To provide a water-based adhesive composition suppressing cost, excellent in adhesion force (normal adhesion force), usable in a conventional coating step without modification and having storage stability for a relatively long time of period. <P>SOLUTION: The water-based adhesive composition includes a resin balloon (A) comprising a hydrophilic group-introduced resin having a hydrophilic group introduction ratio of >1-<10 mass%. In the water-based adhesive composition, the viscosity at 20°C is 15,000-100,000 mPa s, and the specific gravity is 0.60-1.00. <P>COPYRIGHT: (C)2012,JPO&INPIT |
