WATER/OIL REPELLENT COMPOSITION AND ARTICLE

摘要

A water- and oil-repellent agent composition having a lower environmental impact to obtain articles having higher water-repellent friction durability and improved texture. The invention also provides an article treated on the surface with the water- and oil-repellent agent composition. The water- and oil-repellent agent composition includes a first fluoropolymer having structural units based on a first monomer and structural units based on a second monomer; a second fluoropolymer (excluding the first fluoropolymer) having structural units based on a third monomer; and an aqueous medium. The first monomer: compound represented by (Z-Y)nX, where Z is a C1-6 polyfluoroalkyl group or the like, Y is a bivalent organic group or the like, n is 1 or 2, and X is a polymerizable unsaturated group. The second monomer: (meth)acrylate having a C18-30 alkyl group but not a polyfluoroalkyl group. The third monomer: a fluoroolefin.
