PROBLEM TO BE SOLVED: To obtain a stainproofing substrate excellent in stainproofness against oily staining substances especially stainproofness against fingerprints by forming a layer of a specified silicon-containing organic fluoropolymer on the surface of a substrate. SOLUTION: This stainproofing substrate is prepared by forming a layer of a silicon-containing organic fluoropolymer (number-average molecular weight of 5×10<2> to 1×10<5> ) represented by the formula (wherein Rf is a perfluoroalkyl group; Z is fluorine or a trifluoromethyl group; (a), (b), (c), (d) and (e) are 0 or an integer of 1 or greater, a+b+c+d+e>=1; Y is hydrogen or a 1-4C alkyl; X is hydrogen, bromine or iodine; R<1> is hydroxyl or a hydrolyzable substituent; R<2> is hydrogen or a monovalent hydrocarbon group; (l) is 0, 1 or 2; (m) is 1, 2 or 3; and (n) is an integer of 1 or greater). |
