Abstract
This invention provides an antifouling finishing agent comprising a fluorine-containing polymer comprising at least 50% by weight of a fluorine-containing acrylate represented by the formula ##STR1## wherein Y is alkylene group having 1 to 3 carbon atoms, a group of the formula --CH.sub.2 CH.sub.2 N(R)SO.sub.2 -- (wherein R is alkyl group having 1 to 4 carbon atoms) or a group of the formula --CH.sub.2 CH(OZ)CH.sub.2 -- (wherein Z is hydrogen atom or acetyl group), and R.sub.f is fluoroalkyl group having 3 to 21 carbon atoms or fluoralkyl group having 3 to 21 carbon atoms and containing 1 to 10 oxygen atoms in the carbon chain (provided that no oxygen atom is adjacent or closest to other oxygen atom), said fluoroalkyl groups having at least 5 fluorine atoms.
