  • Patent number: 10400115
    Abstract: An aqueous liquid composition contains a water-based medium containing water, a polymer having at least one type of groups selected from hydroxyl groups and amino groups, and phosphonobutanetricarboxylic acid. The aqueous liquid composition contains low-cost materials having low environmental load, can retain adequate viscosity even when stored over a long term, and can form a functional coating film having excellent adhesiveness to a base material and superb durability, solvent resistance and waterproofness and capable of exhibiting various functions led by electrical conductivity and hydrophilicity.
    Type: Grant
    Filed: August 1, 2013
    Date of Patent: September 3, 2019
    Assignee: Dainichiseika Color & Chemicals Mfg. Co., Ltd.
    Inventors: Yoshihiko Iijima, Kozaburo Hayashi, Yosuke Ichinomiya
  • Patent number: 9959985
    Abstract: Provided is an aqueous liquid composition including a water-based medium containing water, a polymer having at least one type of groups selected from hydroxyl groups and amino groups, and phosphonobutanetricarboxylic acid. The polymer is at least one polymer selected from the group consisting of a polysaccharide, polyamino acid, polyvinyl alcohol, polyallylamine, polyvinylamine, a polyamidine, a polyethylenimine, and their derivatives.

  • Patent number: 9181439
    Abstract: A coating formulation for forming a conductive coating film on a surface of a collector for constructing an electrode plate for an electricity storage device is provided. The coating formulation contains (A) a polymeric acid, (B) a vinyl carboxylate copolymer represented by the following formula (1): wherein R1 is selected from the group consisting of H, Na, organic groups derived from vinyl carboxylate monomers, and cations capable of forming electrolytes for the electricity storage device, R2 to R4 are independently selected from the group consisting of H, Na, C1-C6 alkyl groups, and cations capable of forming electrolytes for the electricity storage device, and a ratio (m/n) of m to n is from 0.0001 to 1, (C) a conductive material, and (D) a polar solvent.
