Abstract
Abstract The present invention provides a fluorine-containing water- and oil-repellent composition comprising a fluorine-containing acrylate represented by the formula: <IMAGE> (1) wherein X is a fluorine atom or -CFX1X2 group (wherein X1 and X2 are the same or different and are each a hydrogen atom or fluorine atom), Y is alkylene having 1 to 3 carbon atoms, -CH2CH2N(R)SO2- group (wherein R is alkyl having 1 to 4 carbon atoms) or -CH2CH(OZ)CH2- (wherein Z is a hydrogen atom or acetyl), and Rf is fluoroalkyl having 3 to 21 carbon atoms, or fluoroalkyl having 3 to 21 carbon atoms and 1 to 10 oxygen atoms in its carbon chain (wherein no two oxygen atoms are present adjacent to each other).
