Abstract
A fluoroacrylic compound of formula (1) which, when added to an actinic-ray-curable composition, can impart excellent liquid repellency, antifouling properties, and wear resistance.Y—Rf—Z-Q-[Z—X] (1)[Rfis a divalent perfluoropolyether group. Zis a divalent hydrocarbon group optionally containing O, N, or Si. Qis an (a+1)-valent linking group including a+1 or more Si atoms. Zis a divalent alkylene ether group. X is H or a monovalent organic group having an (α-substituted) acryl group, and at least one of the X moieties is a monovalent organic group having an (α-substituted) acryl group. Symbol a is 1-10. Y is F or —Z-Q-[Z—X]. All of the Zmoiety and the a Zmoieties within the [ ] have been bonded to the Si atoms contained in the Qand the molecule has no urethane bond therein.]
