| 摘要 |
The present invention provides a coating material which can be formed into a coating film having high durability, high hydrophilic properties, and excellent contamination resistance, even if the coating material contains no photocatalyst. The coating film is formed by drying and curing the coating material. The present invention is a coating material, comprising a perfluorocarbon sulfonic acid resin,
wherein the perfluorocarbon sulfonic acid resin is a copolymer including a polymerization unit represented by -(CF 2 -CFZ)-, in the formula, Z being H, Cl, F, or a C1-C3 perfluoroalkyl group, and a polymerization unit represented by -(CF 2 -CF(-O-(CF 2 ) m -SO 3 H))-, in the formula, m being an integer of 1 to 12, and
the perfluorocarbon sulfonic acid resin has an equivalent weight EW of 200 to 1000. |
