Provided are: an aqueous dispersion which has a suitable viscosity and is prepared by using ammonia to disperse, in water, an olefin/α,β unsaturated carboxylic acid copolymer that has a relatively low content of α,β unsaturated carboxylic acid; and a production method for the same. The production method produces an aqueous dispersion composition of a copolymer containing α,β unsaturated carboxylic acid or an ester thereof as a structural unit, and comprises: (1) mixing a copolymer, which contains α,β unsaturated carboxylic acid or an ester thereof as a structural unit, ammonia and water such that the concentration of the copolymer is 30-60 mass%; and (2) using water to dilute the obtained mixture such that the concentration of the copolymer reaches 10-50 mass%. |
