Claim Text:
1. A water- and oil-repellent agent, comprising: a fluorine-containing polymer, which is polymerized at least by a fluorine-containing monomer, a non-fluorinated branched monomer, a non-fluorinated non-crosslinking, a non-fluorinated crosslinking monomer, and an olefin monomer; where X is a hydrogen atom, a monovalent organic group, a halogen atom, a linear fluoroalkyl having 1 to 21 carbon atoms, a branched fluoroalkyl having 1 to 21 carbon atoms, or a cyano; Y is an oxygen atom, a sulfur atom, or a secondary amine; Z is a straight chain alkane, a divalent organic group, aromatics or cycloaliphatic having 6 to 18 carbon atoms, and aliphatic groups having 1 to 10 carbon atoms; and R wherein the non-fluorinated crosslinking monomer is the formula H A is a hydrogen atom or a methyl; A′ is an alkyl of the formula C wherein the non-fluorinated branched monomer is the formula H A is a hydrogen atom or a methyl; A′ is branched primary to tertiary alkyl, and is of the formula C n H m , where n=3-10, m=7-30; wherein the non-fluorinated crosslinking monomer has two or more reactive functional groups; wherein the fluorine-free polymer is 30-70% by weight of the total of the water- and oil-repellant agent; the non-fluorinated non-crosslinking monomer of the fluorine-free polymer is 45-80% by weight of the total of the fluorine-free polymer; the non-fluorinated crosslinking monomer of the fluorine-free polymer is 1-30% by weight of the total of the fluorine-free polymer; and the olefin monomer of the fluorine-free polymer is 10-50% by weight of the total of the fluorine-free polymer; and wherein the fluorine-containing monomer of the fluorine-containing polymer is 45-80% by weight of the total of the fluorine-containing polymer; the non-fluorinated branched monomer of the fluorine-containing polymer is 1-30% by weight of the total of the fluorine-containing polymer; the non-fluorinated crosslinking monomer of the fluorine-containing polymer is 1-10% by weight of the total of the fluorine-containing polymer; and the olefin monomer of the fluorine-containing polymer is 10-50% by weight of the total of the fluorine-containing polymer.
