CLAIMS
What is claimed is:
1. A composition comprising one or more compounds of formula (I) or (II):



(I)


(II)
wherein:
Rf is a linear or branched perfluoroalkyl having 1 to 7 carbon atoms, optionally interrupted by one to three oxygen atoms,
r and q are each independently an integer of 1 to 3,
j is 0 or 1 , or a mixture thereof,
x is from about 1 to about 2,
Z is -O-, -S-, or -NR-,
R is hydrogen or an alkyl group containing 1 to 4 carbon atoms
X is hydrogen or M, and
M is an ammonium ion, an alkali metal ion, or an alkanolammonium ion.
2. The composition of claim 1 wherein Rf is a linear
perfluoroalkyl group having 1 to 3 carbon atoms; r, q, and j are each 1 ; and M is an ammonium or an alkanolammonium ion.
3. The composition of claim 1 comprising a mono(fluoroalkyl) phosphate of formula (I), wherein x is 1 , of from about 15 to about 80 mol%, and a bis(fluoroalkyl) phosphate of formula (I) wherein x is 2, of from about 20 to about 85 mol%.
4. The composition of claim 1 further comprising
A) an agent providing at least one surface effect selected from the group consisting of stain repellency, stain release, soil repellency, soil release, water repellency, oil repellency, antimicrobial,
B) a surfactant, pH adjuster, leveling agent, wetting agent, or
C) a mixture thereof.
5. A method of providing water repellency, oil repellency and stain resistance to a substrate comprising contacting the substrate with a composition of claim 1.
6. A method of providing resistance to blocking, open time extension, and oil repellency to a substrate having deposited thereon a coating composition comprising adding to the coating composition prior to deposition on the substrate a composition of claim 1.
7. The method of claim 6 wherein the coating composition is an alkyd coating, Type I urethane coating, unsaturated polyester coating or water dispersed coating.
8. The method of claim 5 or 6 wherein Rf has 4 to 6 carbon atoms; r, q, and j are each 1 ; and M is an ammonium or an
alkanolammonium ion.
9. A substrate treated according to the method of claim 5 or 6.

10. A substrate to which has been applied a composition of claim 1.
