  • Patent number: 9963615
    Abstract: The present invention relates to a stable aqueous pigment dispersion including: an aqueous medium, pigment particles, and from 0.1% to 15%, by weight based on the weight of pigment, of a certain first water-soluble polymer; and 2) a certain second water-soluble polymer; wherein the dispersant comprises a proportion of the first polymer to the second polymer of from 0.1:1 to 10:1 on a solids basis, and the first polymer and the second polymer are miscible in those proportions; and wherein the dispersant is substantially free of structural units of phosphorus acid monomers and their salts. The invention also relates to a method for forming the stable aqueous dispersion and a dry coating formed from the aqueous dispersion. The stable aqueous dispersion is useful, inter alia, for forming certain composite particles.

  • Patent number: 9469749
    Abstract: The present invention is a composition comprising a) a stable aqueous dispersion of polymer particles functionalized with structural units of a phosphorus acid monomer or a salt thereof and; b) a dispersion of pigment particles stabilized by an adsorbing water-soluble dispersant functionalized with structural units of a sulfonic acid monomer or a salt thereof. The composition of the present invention is useful in providing excellent storage stability for pigmented paints formulated with the sulfonic acid functionalized dispersant described herein.

  • Patent number: 9346972
    Abstract: The present invention is a composition comprising a) a stable aqueous dispersion of polymer particles functionalized with structural units of a phosphorus acid monomer or a salt thereof and; b) a water-soluble polymer functionalized with structural units of a sulfonic acid monomer or a salt thereof as well as a method comprising mixing the stable aqueous dispersion of the phosphorus acid functionalized polymer particles with the sulfonic acid functionalized polymer, and TiO2. The composition of the present invention is useful as a coatings formulation that provides improved hiding over phosphorus acid functionalized binders that do not include the water-soluble polymer. Alternatively, the same hiding benefit is seen at lower phosphorus acid concentration when the sulfonic acid functionalized polymer is present.

  • Publication number: 20070092652
    Abstract: Screen printing methods, processes, apparatuses, and techniques using nanoporous polymeric membranes, and electrical components, such as traces, transistors, circuits, assemblies, and the like additively printed utilizing nanoporous membranes. In one embodiment, the invention includes creating a nanoporous membrane through a chemical process. The membrane is patterned and pores are etched according to a desired pattern. The membrane may then be used to pattern conductive traces on a substrate according to a screen printing or other suitable printing technique.
