1. A coating composition comprising:
(a) a non-zwitterionic compound of the following Formula (I):
[(MO)(Qn)Si(XCH2SO3)3-n]Y2/nr+r  (I)
wherein:
each Q is independently selected from hydroxyl, alkyl groups containing from 1 to 4 carbon atoms and alkoxy groups containing from 1 to 4 carbon atoms;
M is selected from hydrogen, alkali metals, and organic cations of strong organic bases having an average molecular weight of less than 150 and a pKa of greater than 11:
X is an organic linking group;
Y is selected from hydrogen, alkaline earth metals, organic cations of protonated weak bases having an average molecular weight of less than 200 and a pKa of less than 11, alkali metals, and organic cations of strong organic bases having an average molecular weight of less than 150 and a pKa of greater than 11, provided that M is hydrogen when Y is selected from hydrogen, alkaline earth metals and organic cations of said protonated weak bases;
