To provide an aqueous dispersion excellent in adhesiveness and close adhesion with various base materials, storing stability, weather resistance, waterproofness, solvent resistance, etc.
This aqueous dispersion is obtained by blending (I) an aqueous dispersion obtained by dispersing a block copolymer (1) constituted by (A) a polymer block consisting mainly of an olefin-based monomer unit with (B) a polymer block consisting of 2-100 mole% vinyl-based monomer unit having carboxyl group or carboxylic acid anhydride group and 98-0 mole% another vinyl-based monomer unit copolymerizable with the above vinyl-based monomer in an aqueous solution of ≥0.05 equivalent basic substance based on the above carboxyl or carboxylic acid anhydride groups, with (II) a tackiness-imparting agent.
