Patent ID: 7037440

Claim:
A composition comprising the following components: A) a dispersant or a mixture of dispersants, B) an unbranched polyorganosiloxane which contains no epoxy groups and no olefinic carbon-carbon double bonds and no carbon-carbon triple bonds, which is terminated, at both ends of the polysiloxane chain, by units of the formula R 3 Si—O— and which contains, within the polysiloxane chain, units of the formulae (I), (II) and optionally (III) —SiRR 1 —O— (I) —SiRR 2 —O— (II) —SiR 2 —O— (III) which units of the formulae (I) to (III) may be randomly distributed along the chain, where each R radical is independently of the other R radicals a branched or unbranched alkyl radical of 1 to 4 carbon atoms, each R 1 radical is independently of the other R 1 radicals a branched or unbranched alkyl radical of 6 to 24 carbon atoms, and each R 2 radical is independently of the other R 2 radicals a radical of the formula (IV) —R 3 -Ph (IV) where R 3 is a divalent branched or unbranched alkylene radical of 2 to 6 carbon atoms and Ph is an unsubstituted phenyl radical or is a phenyl radical substituted by one or more branched or unbranched alkyl groups of 1 to 4 carbon atoms, and C) a polymer selected from the group consisting of polymers containing perfluoroalkyl (R F ) groups (component C1) and fluorine-free polyurethanes (component C2).
