Patent ID: 8592540

Claim:
A fluorine-containing unsaturated carboxylic acid amide of the following general formula (1) where R 0 represents any of polymerizable double bond-containing groups of the following formulas: R 2 represents a fluorine atom or a fluorine-containing alkyl group; R 3 represents a hydrogen atom, a substituted or unsubstituted C 1 -C 20 straight, branched or cyclic alkyl group or a substituted or unsubstituted C 3 -C 20 aryl group, each of carbon atoms of the alkyl group or the aryl group may be replaced by a carbonyl group, an oxygen atom, a sulfur atom or a silicon atom, each of hydrogen atoms of the alkyl group or the aryl group may be replaced by a halogen atom; W 1 represents a divalent linking moiety constituted by combination of one or two or more organic groups each selected from the group consisting of a single bond, a substituted or unsubstituted methylene group, a divalent alicyclic hydrocarbon group, a divalent aromatic hydrocarbon group, a divalent heterocyclic group, an ether group, a carbonyl group, an ester group, an oxocarbonyl group, a thioether group, an amide group, a sulfonamide group, an urethane group and an urea group; when the linking moiety contains a plurality of organic groups, the organic groups can be of the same kind; an arbitrary number of hydrogen atoms bonded to any carbon atom of the linking moiety may be substituted with a fluorine atom; and carbon atoms of the linking moiety may form a ring with a substituent.
