  • PROCESS FOR PREPARING A COATED PAPER ARTICLE
    Publication number: 20240287743
    Abstract: The present invention relates to a method comprising the steps of applying to a paper or paperboard substrate an aqueous dispersion of polymer particles which comprise structural units of a vinyl ester, vinyl alcohol, and an acrylate monomer, then drying the composition. The method provides a coating that has oil and grease resistance, mineral oil barrier performance, and beat scalability.
