Abstract
An aqueous emulsion may include: an ethylene-vinyl alcohol copolymer (A) as a dispersant; and a polymer (B) containing an unsaturated ethylenic monomer unit as a dispersoid, wherein the ethylene-vinyl alcohol copolymer (A) has a content of ethylene units of 1 mol % or more and less than 20 mol % and a block character of the ethylene units from 0.90 to 0.99. The aqueous emulsion may contain the ethylene-vinyl alcohol copolymer (A), as a dispersant, having a specific structure and is thus excellent in storage stability at low temperatures and water-resistant adhesiveness.
