Abstract:
A fluorinated ether compound, 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 provided. The fluorinated ether compound is represented by A-O—(Rf1O)m-Q1(R1)b, wherein A is a C1-20, perfluoroalkyl group, Rf1 is a perfluoroalkylene group, m is an integer of from 2 to 500, (Rf1O)m a n d may consist of two or more types of Rf1O differing in the number of carbon atoms, Q1 is a (b+1) valent perfluorohydrocarbon group which may have a hydroxy group, R1 is a monovalent organic group having at least one hydrolyzable silyl group, b is an integer of at least 2, and the b R1 may be the same or different.
