Beschreibung
Zusammenfassung:	A water- and oil-repellent comprising an aqueous dispersion of a fluorine-containing copolymer including as a copolymerization unit (a) a perfluoroalkylalkyl (meth)acrylate represented by the general formula CnF2n+1CmH2mOCOCR CH2 (wherein R represents hydrogen atom or methyl group; n represents 4, 5, or 6; and m represents 1, 2, 3, or 4), (b) benzyl (meth)acrylate, (c) a fluorine-free polymerizable monomer other than benzyl (meth)acrylate, and (d) a cross-linkable group-containing polymerizable monomer; and a blocked isocyanate added to the aqueous dispersion in a weight ratio of 0.05 to 3.0 to the weight of the solid content of the aqueous dispersion.
