Water-and oil-repellent composition

摘要

To provide a water- and oil-repellent composition excellent in durability and excellent in safety and preservation of the environment. A water- and oil-repellent composition which comprises (A) a polymer, (B) an aqueous medium and (C) a surfactant in a mass ratio of (A)/(B)/(C)=100/100-500/1-10, the polymer (A) containing a polymerization unit based on a (meth)acrylate having a polyfluoroalkyl group, a polymerization unit based on an alkyl(meth)acrylate having a C₁-C₁₂ alkyl group, a polymerization unit based on an alkyl(meth)acrylate having a C₁₆-C₂₂ alkyl group and a polymerization unit based on a specific compound having a blocked isocyanate group.
