Abstract:
A delaminating coating for use in a thermal transfer system is provided that possesses both delaminating properties and antistatic properties. This delaminating coating can be used on a donor sheet or an intermediate carrying sheet of a thermal retransfer system. The preferred delaminating/antistatic coating is formed from a composition of a vanadium oxide colloidal dispersion.
Abstract:
A coating composition comprises an epoxy silane, an amine hardener that can react with the epoxy silane to form a cross-linked coating, and a stabilizer that includes a sufficient amount of a metal component to delay cross-linking between the epoxy silane and the amine hardener. The coating composition has a shelf life of at least 3 days.
Abstract:
The passage of a container along a conveyor is facilitated by applying to the container or conveyor aqueous compositions containing hardness ions. The compatibility of the aqueous compositions with PET bottles is improved when the ratio of hardness as CaCO3 to alkalinity as CaCO3 is greater than about 1 to 1.

Abstract:
An adhesive composition that includes the reaction product of (a) a polyester-based polyurethane; (b) an epoxy resin; (c) an epoxy-functional silane; and (d) an isocyanate-functional compound, and multilayer laminates in which this adhesive composition is used to bond two polymeric substrates together where at least one of the substrates has an ink-bearing surface.
Abstract:
A vanadium oxide coating useful as an antistatic protection layer on a donor sheet or a receptor sheet of a thermal transfer system is provided. The preferred antistatic coating is formed from a composition of a vanadium oxide colloidal dispersion.
Abstract:
A photographic element comprising a polymeric film base, a silver halide emulsion layer, and an antistatic layer comprising a colloidal vanadium oxide and a vinyl addition polymer dispersion in a dry weight ratio of from 1:30 to 1:500. The antistatic layer may be present as a backing layer on the side of the base opposite the silver halide emulsion layer, as a subbing layer between the base and the emulsion layer in a single or double side coated photographic element, and/or as a subbing layer between the base and a different backing layer. No barrier layer is used over the antistatic layer.

Abstract:
Aqueous-based mixtures comprising colloidal vanadium oxide and a dispersed sulfonated polymer impart antistatic properties to coatings on a substrate and to self-supporting articles. The preferred colloidal vanadium oxide is alkoxide derived and provides mixed valence vanadium oxide wherein the vanadium ions are typically +4 and +5. Preferred sulfopolymers include sulfopolyesters, sulfopolyurethanes, sulfopolyurethanes/ureas, sulfopolyester polyols, and sulfopolyols. Antistatic composite structures comprising colloidal vanadium oxide and a sulfopolymer are also disclosed.
