Patent ID: 8119765

Claim:
A crosslinkable fluorine-containing compound, which is an adduct compound having a crosslinkable group at a terminal functional group of the adduct compound, the adduct compound being derived from a crosslinkable group-introducing agent, wherein the adduct compound is an adduct of a fluorine-containing compound having, per molecule, 2 or more terminal fluorine-containing vinyl groups each directly bonded to an oxygen atom, and a compound having 2 or more groups represented by —XH, where X represents an oxygen atom or a sulfur atom, and wherein the crosslinkable group is represented by any one of the following formulae G1 to G6: wherein R 11 represents a hydrogen atom, a fluorine atom, a trifluoromethyl group or an alkyl group having 1 to 4 carbon atoms; R 21 represents a hydroxyl group, an isocyanato group or a hydrolyzable group; R 22 represents a hydrogen atom or a hydrocarbon group; each of R 31 , R 32 and R 33 independently represents a hydrogen atom or a hydrocarbon group, and any two of these groups may be combined with each other to form a ring; each of R 41 , R 42 , R 43 , R 44 and R 45 independently represents a hydrogen atom or a hydrocarbon group, and any two of these groups may be combined with each other to form a ring; each of R 51 , R 52 and R 53 independently represents a hydrogen atom or a hydrocarbon group, and any two of these groups may be combined with each other to form a ring; R 61 represents a hydrogen atom or a hydrocarbon group; each of “p”, “q”, “r”, “s”, and “t” independently represents an integer of 1 or more; and “n” represents an integer of 1 to 3.
