Patent ID: 7919224

Claim:
A coating material comprising a low-molecular or medium-molecular organic compound represented by general formula (1), wherein R 1 is a single bond, methylene, ethylene or oxygen; R 2 is one selected from the group consisting of (a) a hydrogen atom, (b) a hydrocarbon group, (c) a fluorine-containing alkyl group, and (d) a cyclic form containing an aromatic group or aliphatic group, the hydrocarbon group, the fluorine-containing alkyl group or the cylic form optionally containing a hydroxy group, carboxyl group, amino group, amide group, imide group, glycidyl group, cyano group, fluorocarbinol group, sulfonic group or sulfonylamide group, R 2 may contain a fluorine atom, oxygen atom, nitrogen atom, silicon atom or sulfur atom, and R 2 's of the same type or different type may be connected by an ester bond, amide bond, ether bond, thioether bond, thioester bond or urethane bond, wherein in the general formula (1) at least one R 2 is a group represented by general formula (2) or (3), wherein R 1 and R 2 are the same as those of general formula (1), R 3 is a single bond, a straight-chain alkylene group, or an alkylene group optionally containing a branch or alicyclic structure; and R 4 is one selected from the group consisting of (a) a hydrogen atom, (b) a hydrocarbon group, (c) a fluorine-containing alkyl group, and (d) a cyclic form containing an aromatic group or aliphatic group, the hydrocarbon group, the fluorine-containing alkyl group or the cyclic form optionally containing a hydroxy group, carboxyl group, amino group, amide group, glycidyl group, cyano group, fluorocarbinol group or sulfonic group, and R 4 may contain a fluorine atom, oxygen atom, nitrogen atom, silicon atom or sulfur atom.
