WATER-REPELLING, OIL-REPELLING AGENT COMPOSITION, METHOD FOR PRODUCING SAME, AND ARTICLE

摘要

To provide a water/oil repellent composition which can produce an article which has favorable water/oil repellency and washing durability, into which infiltration of a coating liquid to form a moisture-permeable waterproofing film or the like can be suppressed and which is excellent in the design, and which presents a low environmental impact, its production method and an article having its surface treated with the water/oil repellent composition. A water/oil repellent composition comprising a polymer having structural units based on the following monomer (a) and structural units based on the following monomer (b), and an aqueous medium containing water and the following amide solvent (I) is used. Monomer (a): a compound represented by (Z-Y) n X, wherein Z is a C 1-6 polyfluoroalkyl group or the like, Y is a bivalent organic group having no fluorine atom or the like, n is 1 or 2, and X is a polymerizable unsaturated group. Monomer (b): vinyl chloride. Amide solvent (I): a compound represented by R 1 O(CH 2 ) r (CHR 4 ) s C(O)NR 2 R 3 , wherein r is an integer of from 0 to 3, s is 0 or 1, R 1 is a C 1-3 alkyl group, each of R 2 and R 3 is a methyl group or the like, and R 4 is a hydrogen atom or the like.
