    摘要: The aqueous dispersion of the present invention is an aqueous dispersion in which a biodegradable resin composition (C) in the form of a fine solid is dispersed in an aqueous medium, and the biodegradable resin composition (C) comprises a copolymer (A) comprising a constituent unit (a-1) derived from a polyvalent carboxylic acid and a constituent unit (a-2) derived from a hydroxycarboxylic acid, and a biodegradable resin (B), and wherein the mass composition ratio [(A)/(B)] of the copolymer (A) to the biodegradable resin (B) is 1/99 to 100/0 provided that the total amount of the copolymer (A) and the biodegradable resin (B) is 100.
