Abstract
An aqueous dispersion of a fluorine-containing copolymer comprising, as copolymerization units, (A) a (meth)acrylate represented by [CH═CHRCOO(NH)RNRRR]Y, (B) a perfluoroalkylalkyl(meth)acrylate represented by CFCH(NR'SO)OCOCR═CHor a polyfluoroalkylalkyl(meth)acrylate thereof, or a polyfluoroalkyl(meth)acrylate represented by CF(CHCF)(CFCF)(CHCH)OCOCR═CH, (C) benzyl(meth)acrylate, (D) a fluorine-free polymerizable monomer other than components (A) and (C), and (E) a crosslinkable group-containing polymerizable monomer. The aqueous dispersion can improve the dispersion stability of an aqueous dispersion of a water- and oil-repellent when used as a water- and oil-repellent comprising the fluorine-containing copolymer as an active component.
