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.

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 process for the preparation of a vanadium oxide colloidal dispersion is provided. The process includes a step of hydrolyzing vanadium oxoalkoxide with an excess of water to form a vanadium oxide colloidal dispersion containing at least a minimum effective amount of vanadium and no greater than about 3.5 wt-% vanadium, preferably containing about 0.3 wt-% to about 2 wt-% vanadium. The process can be carried out in the presence of an organic polymer or prepolymer to form a polymeric 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: 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 flexographic printing plate comprising in the following order: a flexible substrate, a photohardenable composition, and a colloidal vanadium oxide antistatic layer. The antistatic layer provides protection from static induced defects until and after the flexographic plate is processed.

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.

Abstract: An abrasive article (i.e., a coated abrasive article or a three-dimensional, low density abrasive article) having a sufficient amount of vanadium oxide incorporated therein to provide having a reduced tendency to buildup static electricity during the abrading of a workpiece. Preferably, the abrasive article further comprises a compatible binder (preferably, a sulfonated polymer) to aid in securing the vanadium oxide to the abrasive article. In another aspect, a method of making the same is taught.
