Abstract
The present invention provides an aqueous dispersion that enables production of a film having improved water resistance, tensile elastic modulus, and stress at break, and with which a decrease of strain at break can be reduced in the film. The present invention relates to an aqueous dispersion comprising an ethylene-vinyl alcohol copolymer (A) and a cellulose nanofiber, the ethylene unit content of the ethylene-vinyl alcohol copolymer (A) being 1 mol % or more and less than 20 mol %.
