FLUORINATED ETHER COMPOUND, FLUORINATED ETHER COMPOSITION, COATING LIQUID AND ARTICLE

摘要

To provide a fluorinated ether compound, a fluorinated ether composition and a coating liquid that are able to form a surface layer which is excellent in water/oil repellency, abrasion resistance, fingerprint stain removability, lubricity and outer appearance, and an article having such a surface layer. A fluorinated ether compound represented by A¹-O—(R^f1O)_m1-Q¹-[C(O)N(R¹)]_p1—R¹¹—C[—R¹²—SiR¹³_n1X¹_3-n1]₃, wherein A¹ is a C_1-20 perfluoroalkyl group; R^f1 is a fluoroalkylene group having no branched structure; m1 is an integer from 2 to 210; Q¹ is a single bond or a fluoroalkylene group having no branched structure; R¹ is a hydrogen atom, etc.; p1 is 0 or 1; R¹¹ is a single bond, an alkylene group, etc.; R¹² is an alkylene group, etc.; R¹³ is a monovalent hydrocarbon group, etc.; X¹ is a hydrolyzable group; and n1 is an integer of from 0 to 2.
