  • Patent number: 7118619
    Abstract: The invention provides for the use of silicone resins obtainable by reacting a) an alkoxysiloxane of the general formula R a 2 ? Si ? ( OR 1 ) b ? O 4 - ( a + b ) 2 with b) one or more hydroxyl-containing polyesters, and if desired c) one or more low molecular weight alcohols, it being possible for the alkoxysilane to be reacted partially and completely, based on the amount of (OR1) groups in a), but the reaction being taken at least to the point where a clear solution is obtained, as dispersants for solids for producing coatings, printing inks and/or print varnishes.
