Abstract
To provide a fluorinated ether composition useful for surface treatment to impart water/oil repellency to the surface of a substrate, a method for producing the fluorinated ether composition, and a coating liquid containing the fluorinated ether composition, as well as a substrate having a surface-treated layer, and a method for producing the same. Said composition comprises at least two fluorinated ether compounds which are represented by A-O-Q-(CFO)—X—O—Band which are different in B. X is a divalent organic group having no CFO. Bis —CHCHCHSiLR, —CHCH(SiLR)CH, —CHCH═CHor —CH═CHCH. A is a perfluoroalkyl group or group B. Of the total of group Bin said composition, the proportion of —CHCHCHSiLRis from 90 to 99 mol %, and the proportion of —CH═CHCHis from 1 to 10 mol %. L is a hydrolyzable group, and R is a monovalent hydrocarbon group. b is an integer of from 1 to 10, and d is an integer of from 1 to 200.
