Patents by Inventor Rebecca P. Hollis

Rebecca P. Hollis has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5695813
    Abstract: An improved latex composition is provided that has been found to exhibit a superior ability to form a substantially uniform polymeric film when applied to a substrate. The composition is capable of being handled and applied to a substrate in the absence of excessive foaming. The aqueous composition includes as essential components specified concentrations of a specifically-defined normally liquid predominantly hydrophobic nonionic ethylene oxide/propylene oxide block copolymer surfactant, and a solely hydrophobic defoaming agent (e. g., a hydrocarbon-based mineral oil). It is possible for the composition to be applied even to a hydrophobic substrate (e.g., a polyester film substrate). Compositions of the present invention, following application to a substrate and the volatilization of the water component, form a substantially uniform polymeric film that can serve as a coating or adhesive.
    Type: Grant

  • Patent number: 5605949

The composition is capable of being handled and applied to a substrate in the absence of excessive foaming. The aqueous composition includes as essential components specified concentrations of a specifically-defined normally liquid predominantly hydrophobic nonionic alcohol ethoxylate surfactant, and a solely hydrophobic defoaming agent (e.g., a hydrocarbon-based mineral oil). It is possible for the composition to be applied even to a hydrophobic substrate (e.g., a polyester film substrate). Compositions of the present invention, following application to a substrate and the volatilization of the water component, form a substantially uniform polymeric film that can serve as a coating or adhesive.

  • Patent number: 5500219
    Abstract: A surfactant/polymer blend with a dissolution rate in water of not greater than 6.5 minutes has 85 to 95% EO/PO block copolymers having in excess of 70% EO, 5 to 15% of one or more polycarboxylates, and 0.1 to 5% of at least one linear alkylbenzene sulfonate.
