A stainproofing agent containing as an active ingredient a polyfluoroalkyl group-containing compound represented by the following general formula and having a molecular weight of from 800 to 3000:
where R, is a polyfluoroalkyl group having from 1 to 20 carbon atoms, X is-R-, -CON(R1)-Q- or-SO2N(R1)-Q- (where R is a divalent alkylene group, R' is a hydrogen atom or a lower alkyl group and Q is a divalent organic group), each of A and A' is -0-, -S- or -N(Z')- (where Z' is a hydrogen atom or a monovalent organic group), Z is a monovalent organic group, W is a trivalent organic group, a is an integer of 1, or 3. A process for the stainproofing agent is also disclosed.
