Document Type and Number:
WIPO Patent Application WO/2024/053354
Kind Code:
A1
Abstract:
A surface treatment agent comprising a fluorine-containing composition which comprises (A) a polymer of formula (1) and/or a product of partial (hydrolytic) condensation thereof and (B) a polymer of formula (2) and/or a product of partial (hydrolytic) condensation thereof in a specific proportion. The surface treatment agent can form cured coating films excellent in terms of water and oil repellency and wear resistance and of slipperiness, chemical resistance, and heat resistance. [Rf is a group of formula (3) (wherein W is an H-containing fluoroalkylene group, d is 1-6, and p, q, r, s, t, u, and v are each 0-450, the sum of p to v being 10-450), Rf' is a fluoroalkyl group, and A is a group of formula (4) (wherein B is a single bond or a divalent group, V is a tri- to octa-valent group, R' is H, OH, an alkyl group, a phenyl group, an oxyalkylene-containing group, an alkoxy group, or a halogen atom, U is a single bond or a divalent group, Z is a single bond or a tri- to octa-valent group, Y is a divalent group, R is an alkyl group or a phenyl group, X is OH or a hydrolyzable group, n is 1-3, m is 1-7, β is 1-6, γ is 0 or 1, and δ is 0-6.)]
