  • Aqueous coating of hydroxy- and acid-functional copolymer and crosslinker
    Patent number: 7408001
    Abstract: The invention relates to aqueous crosslinkable binder dispersions comprising hydroxy-functional copolymers based on ethylene glycol monoallyl ether, to a process for preparing them and to the use of the dispersions in coating materials.
    Type: Grant
    Filed: January 25, 2006
    Date of Patent: August 5, 2008
    Assignee: Bayer Aktiengesellschaft
    Inventors: Martin Melchiors, Rolf Gertzmann, Sandra Grosskopf, Raul Pires
  • Aqueous binder dispersions as coating compositions
    Patent number: 7232860
    Abstract: An aqueous binder dispersion that includes at least one copolymer (P) containing carboxylic acid and/or carboxylate groups. The copolymer (P) includes structural units of carboxyl-free (meth)acrylic esters with a cycloaliphatic structure, and at least 25 mol % of the carboxylic acid groups of the copolymer (P) in the dispersion being present in triethanolamine-neutralized form. The aqueous binder can be used in aqueous coating materials, which can be used to coat a substrate.
    Type: Grant
