<p>A fluoropolymer having a number average molecular weight of 500 to 100000 and represented by the general formula Rf-(OC3F6)a -(OC2F4 )b -(OCF2)c-X-Y-Z-MPnRm-n RnRm-nM-Z-Y-X-(OC3F6)a -(OC2F4)b -(OCF2)c -X-Y-Z-MPnRm-n (wherein Rf represents a perfluoroalkyl group; a, b, and c each independently represents 0, 1 or above, provided that the sum of a, b, and c is at least 1; X represents a group represented by the general formula: -(O)d-(CF2)e -(CH2)f-; Y represents a divalent polar group; Z represents a group represented by the formula: -(CH2)g-; M represents a metal atom; R represents a hydrocarbon group; P represents a hydrolyzable polar group; m represents an integer of (valency of M - 1); and n is an integer of 1 to m). The polymer can form on a substrate an antifouling layer excellent in the antifouling effect on an oleaginous contaminant, particularly on fingerprints.</p> |
