Abstract: The present invention provides a powdered or fibrous or granular or pelleted material, and a method for preparing the material, for measuring glucose concentration in a liquid sample. The devices are typically in the form of a chemically treated granular or powdered or fibrous or pelleted material. The granular or powdered or pelleted or fibrous material is treated with a reagent mixture or solution comprising an enzyme or enzymes, or a combination of an enzyme with a pigment or another compound, a chromogen, and neutralizer. The chromogen in the reagent solution changes color when the reagent solution is exposed to glucose.

Abstract: The present invention relates to amine synergists comprising the structure element of a substituted 1,3-propanedione and their use in radiation or energy curing by actinic light. The amine synergists of the present invention are particularly useful for printing and coating materials wherein low migration and/or low odor is required, such as food packaging and other sensitive packaging applications.

Abstract: A method of recycling plastic articles, such as bottles and labels affixed to bottles, that are printed with UV curable inks, wherein the inks and colorants from the inks are removed as solid particles upon treatment with a hot alkaline solution to provide colorless or nearly colorless plastic materials for recycling that are not contaminated by the inks or colorants.

Abstract: The present invention provides a high opacity solvent based white ink or coating composition that provides high levels of opacity to substrates used for packaging materials that are printed via flexography or gravure. The ink or coating composition contains up to 75 wt % titanium dioxide, while still having a viscosity suitable for flexographic and gravure printing methods.

Abstract: The present application describes a compostable cold seal cohesive composition. The present application also describes a packaging structure comprising the compostable coldseal cohesive composition of the invention.

Abstract: The present invention provides energy curable compositions comprising self-initiating oligomers, amine synergists and Group IV metal chelates. The compositions optionally comprise acrylate monomers having carbonate ester, carbamate, or oxazolidinone groups. The compositions of the present invention exhibit improved cure, and are suitable for packaging, such as food packaging.

Abstract: The present invention provides energy-curable laminating inks and coatings comprising cellulose acetate butyrate (CAB) resins and aminosilanes. When printed and cured on a substrate, the inks and coatings have a color density of at least 1.75, and an adhesive lamination bond strength of equal to or greater than 50 g/linear inch. The energy-curable inks and coatings are suitable for flexographic printing.

Abstract: The present invention provides water-based primer compositions comprising polyolefin type adhesion promoters. Preferably, the polyolefin type adhesion promoter is a maleated polyolefin type adhesion promoter. The primer compositions improve adhesion of water-based inks and coatings to low-treatment substrates.

Abstract: The present invention provides a high opacity solvent based white ink or coating composition that provides high levels of opacity to substrates used for packaging materials that are printed via flexography or gravure. The ink or coating composition contains up to 75 wt % titanium dioxide, while still having a viscosity suitable for flexographic and gravure printing methods.

Abstract: The present invention provides self-disabling tamper evident gift cards, and methods for making and using the gift cards. The gift cards comprise a hidden lower level activation code, and an upper level activation code that is visible. The gift cards incorporate one or more features that render either the lower level or upper level, or both, activation codes unreadable once the lower level activation code is revealed. This prevents card activation at a later time after a first instance when the activation code is accessed.

Abstract: Described herein are printing inks that are safe for direct contact with food. The inks contain colorants and other substances which comply with regulations governing the amounts of substances determined to be safe in the event one or more of the ink-containing substances were to migrate into foods or beverages, The inks exhibit resistance to removal. Also described are sets of inks. The inks provide wide color gamut.

Abstract: The present invention provides ink and coating compositions for printing on non-woven substrates or fabrics. Advantageously, the compositions of the invention can be used either as one component (1K) or two component (2K) ink systems. The compositions of the invention exhibit improved properties, such as ink adhesion ratings, as shown by a rub test, compared to commercially available inks designed to be printed on non-woven substrates.

Abstract: The present invention provides water-based polymeric coatings, which are free of styrene, have enhanced bio-based content, excellent water resistance, grease resistances, and are heat sealable. The coatings are highly suitable for surface treatment of cellulose-based substrates and finished products made therefrom, for example disposable drinking cups.

Abstract: The present invention provides a composition comprising a synergistic combination of at least three dispersant classes, which is used to produce ultra-stable disperse dye dispersions and inks having azo-functional colorants.

Abstract: An electron-beam curable ink or coating for sensitive applications such as food packaging and pharmaceutical packaging.
