  • Patent number: 11326038
    Abstract: Provided is a process for producing a coating on a substrate comprising one or more steps of crushing a dried layer of a foamed aqueous coating composition, wherein the aqueous coating composition comprises a collection of multi-stage copolymer particles having a weight average diameter of 2-20 ?m, wherein said multi-stage copolymer particles comprise a core having a glass transition temperature (Tg) of 20° C. or less. Also provided is a coated substrate made by that process.
    Type: Grant
    Filed: December 6, 2016
    Date of Patent: May 10, 2022
    Assignee: ROHM AND HAAS COMPANY

  • Patent number: 9410053
    Abstract: Provided is an aqueous coating composition including: particular amounts of certain first solid polymeric particles having an average diameter of 0.60-0.99 ?m; certain second solid polymeric particles having an average diameter of 2-20 ?m, and mixtures thereof; and, third solid polymeric particles having a calculated Tg of from ?60 C to 120° C. and an average particle diameter of from 50 nm to 500 nm; wherein the second solid polymeric particles have a K10 value of less than 1.9E+10 N/m2; wherein the difference between the refractive index of the outer surface of the second solid polymeric particles and the refractive index of the third solid polymeric particles is between 10E-4 to 10E-2; and wherein the aqueous coating composition comprises less than 10% by volume, inorganic extender particles. A method for providing a coating from the aqueous coating composition and a low glare coating so formed are also provided.
