R.sup.1 and R.sup.2 are independently a substituted or unsubstituted alkyl, alkenyl, aromatic, aralkyl or alkaryl moiety of C.sub.1 to C.sub.20 ;
R.sup.3 is independently hydrogen or a substituted or unsubstituted alkyl, alkenyl, aromatic, aralkyl or alkaryl moiety of C.sub.1 to C.sub.20 ; and
X is hydrogen, substituted or unsubstituted alkyl, alkenyl, aromatic, aralkyl, or alkaryl moiety of C.sub.1 to C.sub.20 ; --CH.sub.2 CH.sub.2 (CF.sub.2 CF.sub.2).sub.n CF.sub.2 CF.sub.3, wherein n is 1-7; polyoxyalkylene; --C(R.sup.2).sub.2 R.sup.3 Y, wherein R.sup.3 is alkylene or polyoxyalkylene (or a combination thereof), and Y is --OSO.sub.3 H, --SO.sub.3 H, --CO.sub.2 H, --PO.sub.3 H, --OPO.sub.3 H, or a salt thereof; CF.sub.3 (CF.sub.2).sub.q -, wherein q is 1-11, hexafluorobutyl, tetrafluoropropyl, sodium, potassium, lithium, ammonium, or quaternary amine; and v is 0, 1, or 2.
