  • Patent number: 8591999
    Abstract: The invention relates to coatings for leather. In particular it relates to top coats for leather. It provides a leather coating composition comprising an organic synthetic resin in aqueous dispersion and an organopolysiloxane, characterized in that the organopolysiloxane is present in aqueous emulsion and comprises a silicone resin having an empirical formula: (I) where •R is a monovalent organic group having 1-30 carbon atoms, •Z is hydrogen or an alkyl group having 1-4 carbon atoms, •x has a value from 0.75 to 1.7, and •y has a value from 0.1 to 2.0, and having a viscosity of from 1 to 4000 mPa·s at 25° C. We have found that the use of a silicone resin according to the invention greatly increases the abrasion resistance, as measured by the Taber method, of leather coated with the coating composition.
