Abstract:
To provide a fluorinated ether compound, a fluorinated ether composition and a coating liquid, capable of forming a surface layer excellent in water/oil repellency, abrasion resistance, fingerprint stain removability, lubricity, chemical resistance and light resistance, as well as an article having such a surface layer. A fluorinated ether compound represented by A 1 -O-Q 1 -(R f11 O) m1 —R f12 —R 11 —N[—R 12 —SiR 13 n1 X 1 3-n1 ] 2 , wherein A 1 : C 1-20  perfluoroalkyl group, Q 1 : single bond, fluoroalkylene group containing at least one hydrogen atom, etc., R f11 , R f12 : perfluoroalkylene group, m1: integer of from 2 to 200, R 11 : single bond, alkylene group, etc., R 12 : alkylene group, etc., R 13 : monovalent hydrocarbon group, etc., X 1 : hydrolyzable group, n1: integer of from 0 to 2.

Claim (Index 1):
A fluorinated ether compound represented by the following formula (1):\n A 1 -O-Q 1 -(R f11 O) m1 \u2014R f12 \u2014R 11 \u2014N[\u2014R 12 \u2014SiR 13 n1 X 1 3-n1 ] 2 \u2003\u2003(1) wherein\n A 1  is a C 1-20  perfluoroalkyl group, \n Q 1  is a single bond, a fluoroalkylene group containing at least one hydrogen atom, a fluoroalkylene group containing at least one hydrogen atom and having an etheric oxygen atom at its terminal (but excluding the terminal on the side bonded to A 1 -O), a fluoroalkylene group with at least two carbon atoms containing at least one hydrogen atom and having an etheric oxygen atom between its carbon-carbon atoms, or a fluoroalkylene group with at least two carbon atoms containing at least one hydrogen atom and having an etheric oxygen atom between its carbon-carbon atoms and at its terminal (but excluding the terminal on the side bonded to A 1 -O), \n R f11  and R f12  are each independently a perfluoroalkylene group, \n m is an integer of from 2 to 200, \n (R f11 O) m1  may be one composed of at least two types of R f11 O, \n R 11  is a single bond, an alkylene group, an alkylene group having an etheric oxygen atom or \u2014NH\u2014 at its terminal (but excluding the terminal on the side bonded to N), an alkylene group with at least two carbon atoms having an etheric oxygen atom or \u2014NH\u2014 between its carbon-carbon atoms, or an alkylene group with at least two carbon atoms having an etheric oxygen atom or \u2014NH\u2014 between its carbon-carbon atoms and at its terminal (but excluding the terminal on the side bonded to N), \n R 12  is an alkylene group, or an alkylene group with at least two carbon atoms having an etheric oxygen atom or \u2014NH\u2014 between its carbon-carbon atoms, \n R 13  is a hydrogen atom or a monovalent hydrocarbon group, \n X 1  is a hydrolyzable group, \n n1 is an integer of from 0 to 2, \n two [\u2014R 12 \u2014SiR 13 n1 X 1 3-n1 ] may not be the same group.
