Abstract
A fluorinated ether compound which has a poly(oxyperfluoroalkylene) chain (αβ) having a structure of block (α)-block (β) or a structure of block (β)-block (α)-block (β), formed by linking a block (α) comprising at least three Coxyperfluoroalkylene units of at least one type and a block (β) having Coxyperfluoroalkylene units of at least one type, wherein the proportion of the Coxyperfluoroalkylene units is at least 30 mol % among all oxyperfluoroalkylene units constituting the block (β), and which has a hydrolysable silyl group on at least one terminal of the poly(oxyperfluoroalkylene) chain (αβ) via a linking group. Also, a fluorinated ether composition and a coating liquid, whereby it is possible to form a surface-treated layer which has high initial water/oil repellency and which is excellent in abrasion resistance and finger print stain removability, and a substrate having a surface-treated layer and a method for its production.
