  • Patent number: 6303188
    Abstract: A method for improving the dirt pick-up resistance and the retention of gloss on exposure to light of a dried coating formed from a coalescent-free aqueous coating composition is provided. The coalescent-free composition composition contains an aqueous emulsion-polymerized polymeric binder having a glass transition temperature from about −35 C. to about +25 C. with from about 2% to about 20%, by weight based on the weight of the polymeric binder, of at least one copolymerized ethylenically-unsaturated active methylene monomer.
    Type: Grant
    Filed: July 8, 1994
    Date of Patent: October 16, 2001
    Assignee: Rohm and Haas Company
