(57) [Abstract] [Problem] Adhesion and adhesion to various substrates, storage stability, Provided is an aqueous dispersion having excellent weather resistance, water resistance, solvent resistance and the like. SOLUTION: The polymer block (A) mainly composed of an olefin monomer unit and 2 to 100% by mole of a vinyl monomer having a carboxyl group or a carboxylic anhydride group and 2 to 100% by mole of the vinyl monomer A block copolymer composed of a polymer block (B) consisting of 98 to 0 mol% of a unit of another polymerizable vinyl monomer is added in an amount of 0.05 equivalent to the carboxyl group or the carboxylic anhydride group. An aqueous dispersion obtained by blending a polyurethane resin (II) with an aqueous dispersion (I) obtained by dispersing the above-mentioned basic substance in an aqueous solution. |
