  • Patent number: 10767072
    Abstract: The current invention relates to a process for preparing an aqueous binder composition free of organic solvent, the process comprising at least the following steps: A) preparing a hydrophilic vinyl polymer (Polymer A) by polymerisation of a monomer composition A that contains: Ai) at least one carboxylic acid functional olefinically unsaturated monomer; and Aii) at least one olefinically unsaturated monomer different than Ai); and Aiii) optionally at least one wet adhesion promoting olefinically unsaturated monomer different than Ai and Aii); where Polymer A has an acid value (AV) from 32 to 98 mg KOH/g of solid Polymer A; B) preparing a hydrophobic vinyl polymer (Polymer B) by emulsion polymerization of a monomer composition B in the presence of Polymer A where the monomer composition B contains: Bi) at least one olefinically unsaturated monomer; Bii) optionally carboxylic acid functional olefinically unsaturated monomer different than Bi); and Biii) optionally wet adhesion promoting olefinically unsaturated
    Type: Grant

  • Patent number: 9175149
    Abstract: The present invention relates to an aqueous dispersion based on a polymer and a crosslinker, a method for applying a coating to a substrate, and a substrate provided with such a coating. One aspect of the present invention is to provide a formulation for an aqueous dispersion that can be used to obtain a coating that will not turn yellow and is resistant to hydrolysis.
