Abstract
The present invention relates to a water-based fluorine-containing emulsion. This emulsion contains a fluorine-containing copolymer in a disperse phase thereof This copolymer is prepared by copolymerizing: (A) a fluoroolefin, (B) an organosilicon compound containing an olefinic unsaturated bond and an alkoxysilyl group, (C) an unsaturated carboxylic acid represented by a general formula of CH.sub.2 .dbd.CH--(CH.sub.2).sub.n --COOH where n is an integer of from 3 to 15, and (D) at least one other copolymerizable monomer. A paint prepared from the emulsion is superior in storage stability and mechanical stability, although this paint belongs to a one-package paint. A coated film formed by applying the paint is superior in water resistance in its early stages, stain resistance, and weather resistance.
