  • Innovative polyestersiloxane acrylates, their use as additives in radiation-curable coatings and printing inks, and processes for preparing them
    Patent number: 7179877
    Abstract: Innovative polyestersiloxane acrylates obtainable by reacting one or more organically modified polysiloxanes with one or more polyisocyanates having in each case at least two isocyanate groups and one or more polyester acrylates or polyester methacrylates and their use as additives in radiation-curable coatings and printing inks for improving the resistance of the coating toward soiling of all kinds.
    Type: Grant
    Filed: April 16, 2004
    Date of Patent: February 20, 2007
    Assignee: Goldschmidt GmbH

  • Use of silicone resins as dispersants
    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.
