  • Additives for improved hiding and paint compositions containing same
    Patent number: 9453133
    Abstract: The architectural compositions, such as paints and stains, include an additive comprising a plurality of latex particles added to an existing mixture of opacifying pigments and a film-forming binder as an admixture. Each latex particle is made from a latex polymer copolymerized with a polymerizable surfactant. The latex polymer is a non-film forming polymer at ambient temperatures.
    Type: Grant
    Filed: November 3, 2014
    Date of Patent: September 27, 2016
    Assignee: Columbia Insurance Company
    Inventors: Gary Dandreaux, Ashley Brewer, Caleb Jardel, Paulina Ogorzalek, Luz Clarena Shavel, Robert Sheerin

  • Grafted pigment dispersing polymeric additive and paint employing the same with improved hiding
    Patent number: 8895658
    Abstract: The present invention relates to a grafted pigment dispersing polymeric additive for opacifying pigments, prepared by polymerizing monomers in the presence of a polymeric pigment dispersant. The polymeric pigment dispersant has low molecular weight, high acid number and is dissolvable in alkali solution. When incorporated into paint compositions, hiding is improved with less opacifying pigments.
