Patent ID: 7300976

Claim:
A polish composition comprising: i) a base component selected from the group consisting of waxes, silicone oils, hydrocarbon oils and mixtures thereof; and ii) an alkylated fluorochemical oligomeric compound of the formula: (A-L 1 -) n [R 1 -(L 2 -R 2 ) m ] p , wherein A is a fluorochemical oligomeric moiety of the formula wherein the sum of a+b is an number such that the compound is oligomeric, and a is at least 1; R 1 is the residue of an aliphatic or aromtic polyisocyanate; R 3 is hydrogen, halogen, or straight chain or branched chain alkyl containing 1 to about 4 carbon atoms; each R 4 is independently hydrogen or straight chain or branched chain alkyl containing 1 to about 4 carbon atoms; Q and Q′ are each independently a covalent bond or an organic linking group, R f is a fluoroaliphatic group that comprises a fully fluorinated terminal group; R 5 is a fluorine-free aliphatic group; X is a hydrogen atom or a group derived from a free radical initiator; L 1 and L 2 are independently isocyanate-derived linking groups, R 2 is an aliphatic group, n is 1 to 4, m is 0 to 4, and p is 1 to 4, wherein at least one of said R 2 and R 5 groups has 12 or more carbon atoms.
