Abstract: Layers of energy curable inks and coatings containing little to no photoinitiator, are printed over or are covered with ink or coating layers that are not energy curable but do comprise a photoinitiator. All energy curable inks are then simultaneously cured when exposed to actinic radiation that passes through the ink or coating layers that are not energy curable but comprise photoinitiators.

Abstract: The present invention provides devices, and a method for preparing the devices, for measuring glucose concentration in a liquid sample. The devices are typically in the form of test strips. The test strips are printed with a reagent varnish comprising glucose oxidase, peroxidase, chromogen, and neutralizer. The chromogen in the reagent varnish changes color when the reagent varnish is exposed to glucose.

Abstract: The present invention provides an improved method for curing multi-layer constructs of energy curable (EC) inks and coatings with actinic radiation. In the method, one or more layers of EC inks and/or coatings comprising materials that can crosslink or polymerize when exposed to actinic radiation, e.g., monomers, oligomers or polymers, are applied to a substrate, which EC inks and coatings contain little or no photoinitiators. This is followed by applying one or more layers of non-EC inks and/or coatings, which comprise one or more organic peroxides but no readily polymerizable components, over the top of the layers of energy curable inks and/or coatings; and exposing the layers to actinic radiation.

The present invention also relates to use of said water-based ink composition for printing an image on a fibrous substrate by inkjet printing.

Abstract: The present invention provides a method for printing high opacity images or coatings using solvent based inks comprising hollow polymeric microspheres, wherein the inks do not contain titanium dioxide. The International Agency for Research on Cancer (IARC) has classified titanium dioxide as “possibly carcinogenic to humans,” The method of the present invention allows one to avoid the use of inks that rely on titanium oxide for high opacity, which has become of importance for articles that come into contact with one's mouth, for example, cigarette tipping papers.

Abstract: Described herein are ink compositions that will not contaminate recycled plastic materials that come in contact with the inks; labels printed with such inks; and plastic articles having labels printed with such inks; and methods for printing with such inks, and recycled plastic material, such as recycled PET, that has little to no contamination from such inks. For example, during recycling, plastic containers that have been labelled with such inks are subjected to hot caustic wash solutions that cause the ink to separate the labels, When the inks described herein are removed from the label, they form a solid or precipitate, as opposed to dissolving in the hot caustic wash solution. The solid or precipitate is easily separated from the recycled plastic and wash solution, such as by filtration. The separated ink does not contaminate or stain the recycled plastic, or does so to a degree that is tolerable.
