Abstract

An aqueous dispersion of a fluorocopolymer, which is excellent in stability and film-forming properties as an aqueous dispersion and which gives a coating film excellent in weather resistance and mechanical strength and improved in water resistance and stain resistance. The aqueous dispersion comprises water and dispersed therein a fluorocopolymer which comprises (a) polymer units based on a fluoroolefin, (b) polymer units based on propylene, (c) polymer units based on ethylene and/or (d) polymer units based on butylene and which has a melting point within a range of from 40 to 150° C.
