FLUORINE-CONTAINING ETHER COMPOSITION, METHOD FOR PRODUCING SAME, COATING LIQUID, BASE MATERIAL HAVING SURFACE TREATMENT LAYER, AND METHOD FOR PRODUCING SAME

摘要

A fluorine-containing ether composition that can be preferably used for surface treatment that imparts water and oil repellency to the surface of a substrate, a method for producing a fluorinated ether composition, a coating solution comprising the fluorinated ether composition, and a substrate having a surface treatment layer and preparation thereof provision of methods. A composition comprising two or more fluorine-containing ether compounds having different ^{B 10} represented by AOQ-(C _b F _2b O) _d -XOB ^{10 .} X is a divalent organic group having no _{CF 2 O;} B ¹⁰ is -CH ₂ CH ₂ CH ₂ SiL _m R _n , -CH ₂ CH(SiL _m R _n )CH ₃ , -CH ₂ CH=CH ₂ or -CH=CHCH _3. A is a perfluoroalkyl group or Group B ^10. Among the total of ^{groups B 10} present in the composition, _{the ratio of -CH 2} CH ₂ CH ₂ SiL _m R _n is 90 to 99 mol%, and _{the ratio of -CH=CHCH 3} is 1 to 10 mol% . L is a hydrolyzable group, R is a monovalent hydrocarbon group. b is an integer of 1 to 10, and d is an integer of 1 to 200;
