WATER- AND OIL-REPELLENT COMPOSITION, ARTICLE AND PROCESS FOR PRODUCING ARTICLE

摘要

To provide a water/oil repellent composition which presents low environmental impact and is excellent in water and oil repellency and which is capable of preventing penetration of a coating liquid for forming a moisture-permeable waterproofing film and inhibiting delamination of the moisture-permeable waterproofing film. A water/oil repellent composition which comprises a copolymer (A) comprising from 40 to 95 mass% of monomer (a1) units, from 1 to 60 mass% of monomer (a2) units and from 0 to less than 5 mass% of monomer (a3) units, a copolymer (B) comprising from 40 to 91 mass% of monomer (b1) units, from 2 to 20 mass% of monomer (b2) units, from 5 to 20 mass% of monomer (b3) units, and from 2 to 20 mass% of vinyl chloride (b4) units, and a liquid medium (C), wherein monomers (a1) and (b1) are (Z-Y) n X [Z is a C 1-6 polyfluoroalkyl group, etc., Y is a divalent organic group having no fluorine atom, etc., n is 1 or 2, and X is a specific group having a polymerizable unsaturated group], monomers (a2) and (b2) are vinylidene chloride or vinylidene fluoride, and monomers (a3) and (b3) are a (meth)acrylate having a saturated hydrocarbon group having at least 12 carbon atoms.
