1. A polymerizable composition comprising:
(A) a compound containing a repeating unit having a polyether structure having a fluorine atom and four or more polymerizable groups and being represented by the following formula (I); (B) a photopolymerization initiator; and (C) an organic solvent:wherein Rf1 to Rf4 each independently represents a fluorine atom, an alkyl group having a fluorine atom or a group represented by —CF2—O—(CF2)m1F, m1 represents an integer of 1 or more, n1 represents a number of the repeating unit and is a positive integer, Rf5 to Rf8 each independently represents a fluorine atom, an alkyl group having a fluorine atom or a group represented by —CF2—O—(CF2)m2F, n2 and n3 each independently represents a positive integer, when n2 or n3 is 2 or more, two or more Rf5s, two or more Rf6s, two or more Rf7s or two or more Rf8s may be same as or different from each other, m2 represents an integer of 1 or more, Rf9 and Rf10 each independently represents a hydrogen atom, an alkyl group having a fluorine atom or a group represented by —CF2—O—(CF2)m3F, m3 represents an integer of 1 or more, L1 represents a (p1+1) valent aliphatic connecting group, L2 represents a (p2+1) valent aliphatic connecting group, p1 and p2 each independently represents an integer of 2 or more, and X1 and X2 each independently represents a group having a polymerizable group, and
wherein at least one of Rf1 to Rf8 in the formula (I) is a straight chain perfluoroalkyl group having from 2 to 8 carbon atoms or a group represented by —CF2—O—(CF2)mF in which m represents an integer from 1 to 10, and Rf9 and Rf10 each independently represents a hydrogen atom, a straight chain perfluoroalkyl group having from 2 to 8 carbon atoms or the group represented by —CF2—O—(CF2)m3F. |
