WATER- AND OIL-REPELLENT

Disclosed is a water-repellent oil-repellent agent obtained by adding a blocked isocyanate into an aqueous dispersion of a fluorine-containing copolymer at a weight ratio of 0.05-3.0 relative to the solid content in the aqueous dispersion. The fluorine-containing copolymer contains, as copolymerizat...

Beschreibung
Zusammenfassung:	Disclosed is a water-repellent oil-repellent agent obtained by adding a blocked isocyanate into an aqueous dispersion of a fluorine-containing copolymer at a weight ratio of 0.05-3.0 relative to the solid content in the aqueous dispersion. The fluorine-containing copolymer contains, as copolymerization units, (a) a perfluoroalkylalkyl (meth)acrylate represented by the following general formula: C n F2n+1C m H2m OCOCR=CH2 (wherein R represents a hydrogen atom or a methyl group, n represents 4, 5 or 6, and m represents 1, 2, 3 or 4), (b) a benzyl (meth)acrylate, (c) a fluorine-free polymerizable monomerother than benzyl(meth)acrylates and (d) a crosslinkable group-containing polymerizable monomer.
