ABSTRACT:
A fluorine-containing coating agent which can be used for forming a fluorocarbon resin coating film on a substrate comprises a polymer which has a fluorine-containing polymer as a main chain and an alkoxysilyl group in the side chain and which is obtained by the reaction of a hydroxyl group of a fluorine-containing polymer having the hydroxyl group in the side chain with an isocyanato group of an alkoxysilane having the isocyanato group. The fluorine-containing polymer having a hydroxyl group in the side chain is a copolymer of a fluoro-olefin and a hydroxyalkyl vinyl ether having a straight or branched alkyl group having 2 to 5 carbon atoms. The alkoxysilane having an isocyanato group is a compound represented by the following formula:
