STAIN-PROOFING AGENT COMPOSITION, METHOD FOR PRODUCING THE SAME, AND ARTICLE PROCESSED WITH THE SAME

摘要

To provide an antifouling composition which is a fluorine-type antifouling composition using a short chain perfluoroalkyl group and which is excellent in antifouling properties and water/oil repellency and presents good durability against washing.
An antifouling composition comprising a fluorocopolymer which comprises from 30 to 65 mass% of polymerized units (a) having a C 1-6 perfluoroalkyl group, from 1 to 67 mass% of polymerized units (b1) having -(C 2 H 4 O)- and from 3 to 34 mass% of polymerized units (b2) having -(C 4 H 8 O)-, wherein the content of -(C 2 H 4 O)- is from 20 to 65 mass%, and the content of -(C 4 H 8 O)- is from 2 to 13 mass%.
