  • Aqueous resin composition
    Patent number: 6566426
    Abstract: The present invention provides an aqueous resin composition, which has good driability, and which is excellent in adhesion and various resistances, particularly, water and solvent resistances. The aqueous resin composition comprises a combination of: an anionic resin and/or an amphoteric resin; a polyoxazoline compound; and a multivalent metal compound.
    Type: Grant
    Filed: July 23, 2002
    Date of Patent: May 20, 2003
    Assignee: Nippon Shokubai Co., Ltd.
    Inventors: Kenta Kanaida, Makoto Mizushima, Koichiro Saeki, Takashi Miyai
  • Aqueous resin composition and curing process
    Patent number: 5990226
    Abstract: There is provided an aqueous resin composition which does not cause coagulation, can be cured at low temperature, and, by this curing, forms a coating superior in mechanical strength, water resistance, solvent resistance and adhesion to various substrates. The aqueous resin composition of this invention comprises an oxazoline group-containing polymer (A), a carboxyl group-containing polymer (B), and an acidic compound-amine salt catalyst (C). The curing is carried out by a reaction between the oxazoline group-containing polymer (A) and the carboxyl group-containing polymer (B) in the presence of the acidic compound-amine salt catalyst (C).
