Abstract:
A hydrophilic coating composition for hydrophilically coating a metallic surface, said coating composition comprising a hydrophilic polymer comprising units of hydrophilic monomer and units of fluorocarbon-containing hydrophobic comonomer, said coating composition producing hydrophilic coatings on the metallic surface having a contact angle below about 50.degree., wherein said units of hydrophilic monomer include units selected from the group consisting of acrylamide, vinyl acetate, vinyl alcohol, vinyl pyrrolidone and mixtures thereof, wherein said units of hydrophilic monomer further include units selected from the group consisting of hydrophilic cationic and anionic monomers, said hydrophilic polymer being a terpolymer comprising units having the formula: ##STR11##where R.sup.1 =H or CH.sub.3 ; ##STR12##x=an organic linking group;p=0 or 1;R.sub.f =is a perfluoronated alkyl or perfluoronated poly-(alkyleneoxy) group;m=0.01-10 mole percent;n+i=90-99.99 mole percent;n/i=molar ratio=10/90 to 90/10; and ##STR13##
