Document Type and Number:
WIPO Patent Application WO/2023/204026
Kind Code:
A1
Abstract:
A water- and oil-repellent article obtained by a production method according to the present invention comprises: a substrate; a silicon oxide underlayer formed on an outer surface of the substrate by a dry method; and a water- and oil-repellent surface layer which is mainly composed of a fluoropolyether group-containing polymer having a specific structure of a hydrolyzable silyl group and/or a partially hydrolyzed-condensed product thereof, and which is formed on the outer surface of the silicon oxide underlayer by a wet method. Said water- and oil-repellent article exhibits excellent water- and oil-repellency, and wear resistance.
