WATER-BASED PRESSURE-SENSITIVE ADHESIVE COMPOSITION, PRODUCTION METHOD THEREFOR AND ADHESIVE PRODUCT

摘要

PROBLEM TO BE SOLVED: To obtain a water-based pressure-sensitive adhesive composition which has excellent adhesiveness and repulsion resistance to a nonpolar adherend when used as an adhesive prodcut and further excellent water resistance, to provide a production method therefor and an adhesive product having the characteristics. SOLUTION: The composition contains an acrylic polymer having a (meth) alkyl acrylate or an alicyclic ester as a main monomer component in which a solvent-soluble content is 20-90 wt.% based on the total solid content. As the solvent-soluble content, (A) an acrylic polymer having a glass-transition temperature of -20 deg.C or less and a weight average molecular weight of 100,000 or more and (B) an acrylic polymer having the temperature of 40 deg.C or more and the weight of 300-50,000 are contained.
