摘要:
A fluorine-containing ether compound represented by R1—R2—CH2—R3—CH2—R4—R5 is provided. (R3 is a perfluoropolyether chain; R1 and R5 are each independently any one of an alkyl group that may have a substituent, an organic group having at least one double bond or at least one triple bond, and a hydrogen atom; and —R2—CH2—R3 is represented by Formula (2), and R3—CH2—R4— is represented by Formula (3)) -[A]-[B]—O—CH2—R3 (2) R3—CH2—O—[C]-[D]- (3) ([A] is represented by Formula (4), [B] is represented by Formula (5), [C] is represented by Formula (6), [D] is represented by Formula (7), and in the formula, a and b are integers of 0 to 2, c is an integer of 2 to 5, d and f are integers of 0 to 2, and e is an integer of 2 to 5, and at least one of b and d in the formula is 1 or more)
