An aqueous emulsion is a water-based emulsion containing a dispersant and a dispersant; it contains modified polyvinyl alcohol (A) and a compound (B) as the dispersant, and a polymer containing an ethylenically unsaturated monomer unit ( E) As the aforementioned dispersant; the modified polyvinyl alcohol (A) has a 0.001 to 2 mole% double bond in the side chain; and the compound (B) is selected from the group consisting of the following (B1), (B2), and (B3) At least one of the group of: a compound having a conjugated double bond and having 2 or more hydroxyl groups bonded to the conjugated double bond or a salt thereof or an oxide thereof (B1), an alkoxyphenol (B2), And a cyclic nitrogen oxide radical (nitroxyl radical) (B3); and the content of the dispersant is 1 to 20 parts by mass based on 100 parts by mass of the polymer (E). The adhesive obtained by using this aqueous emulsion has excellent water resistance and heat resistance, and has excellent bonding strength. This adhesive is also excellent in coatability and storage stability. |
