  • Patent number: 11505645
    Abstract: A solvent-less hybrid curable composition is prepared from grafting polyesters or polyamides onto a (meth)acrylic copolymer backbone. Besides the many benefits of a solvent-less system, the hybrid curable composition forms strong adhesion to polar substrates, widens the use temperatures, and enables faster processing speeds than conventional hybrid curable compositions. The solvent-less hybrid curable composition forms an optically clear single phase that is suitable as tapes and labels, or in electronic, optoelectronic, OLED and photovoltaic devices, and the like.

  • Patent number: 11466152
    Abstract: The present technology relates generally to aqueous dispersion or emulsion compositions that include a polymeric binder resin and an ether amine. Specifically, the polymeric binder resin includes acid functional groups, at least a portion of which are neutralized by the ether amine such that the polymeric binder resin is dissolved or dispersed in the water, provided that the polymeric binder resin is not a polyurethane and the ether amine is a compound of formula I: wherein R1 and R2 are independently C1-C4 alkyl or C3-C4 cycloalkyl group; or R1 and R2, together with the nitrogen to which they are attached, form a C4-C5 membered heterocycloalkyl ring; A is a C1-C6 alkylene or C1-C6 cycloalkylene ring; and R3 is C1-C4 alkyl or C3-C4 cycloalkyl group; provided that the compound of formula I contains no more than 10 carbons.

  • Publication number: 20090088516
    Abstract: A system and method to improve the color acceptance of color viscosity stabilized latex paints. The system includes a base paint, 0.05 wt % to 5 wt % of a color viscosity stabilizing compound; a colorant compound, and; a sufficient amount of a hydrophobically modified alkali swellable emulsion (“HASE”) thickener to improve the color acceptance properties of the paint, which amount is typically 0.02 wt % to 0.5 wt % of the paint, and optionally, 0.1 wt % to 5 wt % of a condensation polymer associative thickener including polyether polyurethanes, polyether polyols, polyether polyacetals, and polyether aminoplasts. The system demonstrates improved color acceptance as measured by rub-ups and ?E values.
