    Abstract: Processes for producing a fluorinated ether compound are provided by which fluorinated ether compound capable of imparting excellent water/oil repellency, to a substrate surface or a hard coat layer can be easily produced in high yield. A process comprising reacting Rf(CF2)a—CF2OC(═O)Rf4 or Rf(CF2)a—C(═O)X1 with HN(—R1CH═CH2)2 to obtain Rf(CF2)a—C(═O)N(—R1CH2═CH2)2 and a process comprising obtaining the above product and reacting the product with HSiR2nL3-n to obtain Rf(CF2)a—C(═O)N(—R1CH2CH2SiR2nL3-n)2 wherein Rf is a linear polyfluoroalkyl group having at least two carbon atoms and at least one etheric oxygen atom between carbon atoms, Rf4 is a C1-30 perfluoroalkyl group or the like, X1 is a halogen atom, R1 is an alkylene group, a is an integer of from 1 to 5, R2 is a monovalent hydrocarbon group, L is a hydrolyzable group, and n is an integer of from 0 to 2.

    Abstract: To provide a fluorinated ether compound capable of forming a surface layer excellent in initial water/oil repellency, fingerprint stain removability, abrasion resistance and light resistance; a fluorinated ether composition and a coating liquid containing the fluorinated ether compound; an article having a surface layer excellent in initial water/oil repellency, fingerprint stain removability, abrasion resistance and light resistance and a method for producing it. A fluorinated ether compound having a poly(oxyperfluoroalkylene) chain having a unit (a) which is an oxyperfluoroalkylene unit having 5 or 6 carbon atoms, and a unit (P) which is an oxyperfluoroalkylene unit having at most 4 carbon atoms, and having at least one of a hydrolysable silyl group and a silanol group on at least one terminal of the poly(oxyperfluoroalkylene) chain via a linking group.
