Abstract:
A fluorinated ether compound represented by A-O—(Rf1O)m—Rf2—[C(O)N(R1)]p-Q1-C(R2)[-Q2-SiR3nL3-n]2, wherein A is a C1-20 perfluoroalkyl group, Rf1 is a linear fluoroalkylene group, m is an integer of from 2 to 500, Rf2 is a linear fluoroalkylene group, R1 is a hydrogen atom or an alkyl group, p is 0 or 1, Q1 is a single bond or an alkylene group, R2 is a hydrogen atom, a monovalent hydrocarbon group or the like, Q2 is an alkylene group, R3 is a hydrogen atom or a monovalent hydrocarbon group, L is a hydrolyzable group, and n is an integer of from 0 to 2 is provided. A fluorinated ether composition and a coating liquid capable of forming a surface layer excellent in initial water/oil repellency, fingerprint stain removability, abrasion resistance, light resistance and chemical resistance, an article having a surface layer, and a method for producing it are also provided.
