摘要:
The present invention provides: a fluorinated ether compound and a coating liquid capable of forming a surface layer excellent in water/oil repellency, abrasion resistance, fingerprint stain removability and lubricity and an article having a surface layer excellent in water/oil repellency, abrasion resistance, fingerprint stain removability and lubricity. Provided is a fluorinated ether compound represented by [Rf-G-]aZ[—(O—R2)c—SiR3nL3−n]b wherein Rf: a linear polyfluoroalkyl group having at least two carbon atoms, which has at least one etheric oxygen between carbon-carbon atoms, G: —R1—O—, —R1—CONH—, —CONH— or a single bond, R1: an alkylene group, Z: a hydrocarbon group having a valence of (a+b) or the like, R2: an alkylene group, R3: a monovalent hydrocarbon group or the like, L: a hydrolyzable group, n: from 0 to 2, a: an integer of at least 1, b: an integer of at least 1, (a+b): at least 3, when a is 1, b is at least 4, and when a is at least 2, b is at least 1, and c: 0 or 1.
