Abstract
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:
(R.sub.f -X-A-CONH).sub.a W-NHCO-A'"'"'-Z).sub.3-a
where Rf is a polyfluoroalkyl group having from 1 to 20 carbon atoms, X is --R--, --CON(R1)--Q-- or --SO2 N(R1)--Q-- (where R is a divalent alkylene group, R1 is a hydrogen atom or a lower alkyl group and Q is a divalent organic group), each of A and A'"'"' is --O--, --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, 2 or 3. A process for the stainproofing agent is also disclosed.

5. A process for preparing a stainproofing agent, which comprises
reacting a mixture of polyfunctional isocyanate compounds having at least three --NCO groups and a --NHCON< - bond derived from an addition reaction of a >
H--N group-containing compound III with a --NCO group-containing compound IV, wherein the compound III is derived from OCH--Y--NCO, wherein Y is selected from the group consisting of --(CH2)6 -- and ##STR47## and the compound IV is OCN--Y--NCO or derived from OCN--Y--NCO where Y is as defined above,with a compound of the formula Rf --X--A--H wherein Rf is a polyfluoroalkyl group having from 1 to 20 carbon atoms, X is --R--, --CON(R1)--Q-- or --SO2 N(R1)--Q--, wherein R is alkylene, R1 is a hydrogen atom or a lower alkyl group and Q is a alkylene, and A is --O--, --S-- or --N(Z'"'"')-- wherein Z'"'"' is a hydrogen atom or a lower alkyl group, and, if required, further reacting the mixture with a compound of the formula Z--A'"'"'--H, wherein A'"'"'--Z is selected from the group consisting of ##STR48## --OR'"'"', --OCH2 CH2 CN, --OCH2 CH2 NO2, --OCH2 CH2 OH, --NHCH2 OH, --NHCH2 CH2 OH, ##STR49## --NHR'"'"', --NR'"'"'R'"'"', --N(CH2 CH2 OH)2 and ##STR50## where R'"'"' is an alkyl group, to form a mixture of polyfluoroalkyl containing compounds having at least one --NHCO--A--X--Rf group wherein A, X and Rf are as defined above, having a molecular weight of at most 8000 and, if required, at least one --NHCO--A'"'"'--Z group wherein A'"'"'--Z is as defined above, provided that the total of the --NHCO--A--X--Rf groups and the number of --NHCO--A--Z groups is at least three. - View Dependent Claims (6, 7)
