    • The present invention is a fluorine-containing acrylate or alpha-substituted, fluorine-containing acrylate, represented by the following formula (1):

      wherein a is an integer of from 1 to 4 and b is an integer of from 1 to 4, provided that the total of a and b is 3, 4, or 5;
      R 1 is a group represented by the following formula (2):

               -(C 4 H 8 O) d (C 3 H 6 O) e (C 2 H 4 O) f (CH 2 O) g -     (2)

      wherein d, e, f, and g are, independently of each other, an integer of from 0 to 4, provided that the molecular weight of R 1 is in the range of 30 to 300, and
      these repeating units may be sequenced at random;
      R 2 is an acryl group- or alpha-substituted acryl group-containing group having 4 to 20 carbon atoms and represented by the following formula (3):

      wherein R 3 is, independently of each other, a hydrogen atom, a fluorine atom, a methyl group, or a trifluoromethyl group,
      R 4 is a divalent or trivalent linking moiety having 1 to 18 carbon atoms, optionally having an ether bond and/or an ester bond, and
      n is 1 or 2;

      Rf is a perfluoropolyether residue represented by the following formula (4):

      wherein j, k, 1, and m are, independently of each other, an integer of from 0 to 50, provided that the molecular weight of Rf is in the range of 200 to 6000,
      X is a fluorine atom or a trifluoromethyl group, and these repeating units may be sequenced at random;
      Z is a divalent organic group; and
      c is 0 or 1.
