The compound represented by the formula (I).

In the formula (I),
A ³ is a divalent hydrocarbon group of a carbon number of ₂ ~ 36, -CH 2 contained the hydrocarbon groups - is, being optionally substituted by a -O-, -S- or -CO-, hydrogen atoms contained hydrocarbon groups that It is, or may be substituted with a halogen atom or a hydroxyl group.
Q ¹ and Q ² are, each independently, represents an alkyl group with a fluorine atom or a perfluoroalkyl group having 1 to 6 carbon atoms.
R ¹ and R ² are, each independently represents a perfluoroalkyl group of a hydrogen atom, a fluorine atom or a group having 1 to 6 carbon atoms.
z is 0-6 represents an integer that is, when z is 2 or greater, the plurality of R ¹ and R ² may be the same or different from each other.
X ¹ is, * 1-CO-O-, * 1-O-CO-, * 1-O-CO-O- or represents -O-, * 1 is ^{C (R 1) (R 2} ) or C (Q ¹⁾ represents a bonding site with (Q ^2).
A ¹ is, that represents a divalent hydrocarbon group having 2 to 36 which may have a substituent, -CH ₂ groups that contained a hydrocarbon-substituted by - is, -O-, -S-, -CO- or -SO ₂ It may be.
X ² is, * 2-CO-O-, * 2-O-CO-O- or represents -O-, * 2 denotes the binding site of the A ^1.
