Claims
- 1. A composition consisting essentially of:
- (a) a perfluoroalkyl group-containing phosphoric acid ester represented by the formula:
- (R.sub.f YC.sub.q H.sub.2q O).sub.n PO(OH).sub.3-n
- wherein R.sub.f represents a perfluoroalkyl having 4 to 20 carbon atoms;
- Y is CH.sub.2 CH(Z) where Z is H, CH.sub.3, C.sub.2 H.sub.5, Cl or OR where R is H, CH.sub.3, C.sub.2 H.sub.5, COCH.sub.3, COC.sub.2 H.sub.5 or CH.sub.2 COOH or its salt, or SO.sub.2 N(R') where R' is an alkyl group having 1 to 4 carbon atoms;
- q is an integer of 0 to 4 when Y is CH.sub.2 CH(Z) or 1 to 4 when Y is SO.sub.2 N(R'); and
- n is an integer of 1 to 3, or a salt thereof;
- (b) a polyoxyethylene alkylamine having 7-20 oxyethylene groups (--CH.sub.2 CH.sub.2 O--) and an alkyl group of 12 to 18 carbon atoms; and
- (c) a liquid carrier.
- 2. A composition according to claim 1 wherein said liquid carrier comprises water.
- 3. A composition according to claim 2 wherein said polyoxyethylene alkylamine is present in an amount 0.05 to 2.0 parts by weight per one part by weight of said perfluoroalkyl group-containing phosphoric acid ester.
- 4. A composition according to claim 1 wherein said polyoxyethylene alkylamine is present in an amount 0.05 to 2.0 parts by weight per one part by weight of said perfluoroalkyl group-containing phosphoric acid ester.
- 5. A composition according to claim 1 wherein said liquid carrier comprises an organic solvent.
- 6. A composition according to claim 5 wherein said organic solvent is selected from the group consisting of acetone, isopropanol, trichlorofluoromethane, 1,2-difluorotetrachloroethane and 1,1,2-trichlorotrifluoroethane.
- 7. A composition according to claim 1 wherein said polyoxyethylene alkylamine is present in an amount 0.05 to 10 parts by weight per one part by weight of said perfluoroalkyl group-containing phosphoric acid ester.
- 8. A composition according to claim 1 wherein the total amount of said polyoxyethylene alkylamine and said perfluoroalkyl group-containing phosphoric acid ester ranges from 0.1 to 50 weight %.
- 9. A composition according to claim 1 wherein said integer n is 1 or 2.
- 10. The composition according to claim 1 in which the polyoxyethylene alkylamine has 7 oxyethylene groups (--CH.sub.2 CH.sub.2 O--) and an alkyl group of 12 carbon atoms.
- 11. The composition according to claim 1 in which the polyoxyethylene alkylamine has 20 oxyethylene groups (--CH.sub.2 CH.sub.2 O--) and an alkyl group of 18 carbon atoms.
