The present invention relates to aqueous coating compositions, oil repellent articles and methods of forming coatings on substrates. The aqueous coating composition comprises at least the following components: organopolysiloxane (A), which is a polysiloxane compound having at least two alkenyl groups per molecule; organohydrogenpolysiloxane (B), which is A polysiloxane compound comprising at least two Si H groups per molecule; a hydrosilylation catalyst (C) capable of catalyzing the reaction between an organopolysiloxane compound (A) and an organohydrogenpolysiloxane compound (B) The hydrosilylation reaction; organic copolymer (D), comprising at least two types of repeating units (i) and (ii): unit (i), which is an alkyl group containing 2 to 2 carbon atoms, unit (ii), which is an alkyl group containing 2 to 12 carbon atoms and having at least one pendant alcohol substituent; water, and the composition is capable of being formed by hydrosilylation of the coating on a substrate upon curing. |
