  • Patent number: 6333368
    Abstract: A curable composition useful in water-based paints comprises a water-based product obtained by dispersing or dissolving in water a vinyl polymer (II) containing tertiary amino and/or acidic groups which have been neutralized by an acidic or basic compound, an epoxy and hydrolysable silyl groups-containing compound (B), and a hydrolysable silyl and/or silanol groups-containing compound (F).

  • Patent number: 6103788
    Abstract: The present invention relates to a curable resin composition for use in water-based coating materials which includes as essential components an emulsion polymer (A) containing tertiary amino groups obtained by carrying out emulsion polymerization of a vinyl monomer containing a tertiary amino group with another copolymerizable vinyl monomer in a water-based medium, and a compound (B) containing, at least, an epoxy group and a hydrolyzable silyl group, with this composition preferably also including a water-based compound (C) obtained by adding a neutralizing agent to a vinyl polymer (I) containing acidic groups and/or tertiary amino groups so as to neutralize at least 10% of the acidic groups and/or the tertiary amino groups, and then dispersing or dissolving in water, and/or a compound (D), which is not included in compound (B), and contains hydrolyzable silyl group and/or a silanol group.

  • Patent number: 6072000
    Abstract: The present invention proposes highly practical curable resin compositions for use in water based paints, which contain no, or much less organic solvent when compared with current organic solvent based paints, and which produce painted surfaces which have excellent curability and weather resistant properties, as well as excellent resistance to solvents, chemicals and water. These curable resin compositions include a compound combining both epoxy and hydrolyzable silyl groups, and a water based product obtained by dispersing or dissolving in water, a tertiary amino vinyl polymer, a vinyl polymer containing both tertiary amino and acidic groups, or an acidic vinyl polymer, which has been either partially or completely neutralized by an acidic or basic compound.
