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: Described herein are printing ink compositions suitable for printing of microwavable flexible packaging. The printed black ink exhibits low microwave energy absorption, thus minimizing the risk of charring, arcing, ignition, distortion or burning during microwave heating processes. Nitrocellulose resin, a solvent, a polyurethane resin, and a carbon black pigment having at least one of an imaginary permittivity of ?3, preferably ?2, and a surface oxygen content of 1 wt % to 3 wt %, preferably 1.5 wt % to 2.5 wt % are among the components of the printing ink compositions. Also described is packaging suitable for exposure to microwave energy upon which the inks have been printed.
Abstract: Described herein are polymer-encapsulated materials and a method for encapsulating materials with polymer via emulsion polymerization. The encapsulated materials include colorants (e.g., pigments and dyes, and in particular fluorescent dyes), optical brighteners, downconverters and upconverters. The encapsulated materials are produced by the emulsion polymerization of ethylenically unsaturated monomers. The polymer-encapsulation method described herein does not require the preparation of a miniemulsion homogenized with special equipment, such as an ultrasonification device, and the resulting polymer-encapsulated materials exhibit optical properties superior to polymer-encapsulated materials prepared by processes that include the preparation of a miniemulsion prepared with such special equipment, such as an ultrasonification device.

Abstract: The described herein is a method for identifying a best match to a metal deco target color and distributing the best match to interested parties for ongoing validation. The method creates a digital proofing database that matches, for example, PantoneLIVE™ target colors and sets a defined digital inkjet standard to within desired tolerances. Also described is a system that implements the method.
Abstract: The present invention provides a coating composition comprising one or more polyamide resins and one or more polyethylenimine (PEI) resins, preferably dissolved in one or more solvents. When used as a primer, the coating composition of the present invention improves adhesion of subsequently printed inks and coatings to the substrate. Advantageously, the coating composition of the present invention used as a primer improves adhesion of inks and coatings to metallized film substrates.
Abstract: Described herein are inks and coating compositions curable by exposure to UV energy sources including UV-LED energy sources, which include a polymerizable component selected from an ethylenically unsaturated materials, a photoinitiator component that is one or more photoinitiators, one of which is an acyl phosphine oxide photoinitiator; and a Group IV metal chelating agent. Improved cured is realized for the described inks and coating compositions.

Abstract: The present invention provides thermochromic liquid crystal inks and coatings. The ink and coating compositions comprise one or more non-encapsulated cholesteryl materials, one or more resins that are not cholesteryl materials, and one or more solvents. In certain embodiments, a thermochromic effect is observed at about body temperature.
Abstract: Described herein are compositions suitable for use as binder components for inclusion in printing inks and coatings, such as those used in the gravure and flexographic printing process and which are printed on substrates such as polyolefin (e.g., polyethylene, polypropylene) and poly(ethylene terephthalate) (PET). The compositions are non-aqueous dispersions in which an one or more ethylenically unsaturated acrylates or (meth)acrylates is polymerized with a polyurethane, polyurethane-urea or polyurea in a non-aqueous polymerization medium, such as esters, ketones, and mixtures thereof, forming polymeric hybrid resins in the polymerization medium, which are solvent-dispersible hybrid resins of polyurethane-polyacrylate, polyurethane-urea-polyacrylate, and polyurea-polyacrylate. Films of hybrid resins are also disclosed.

Abstract: The present invention is drawn to UV-curable ink and coating compositions comprising cleavage type photoinitiators and acids. The acids may be inorganic or organic acids, or acids generated by a photoacid generator during UV-cure. Incorporation of the acids into the UV-curable ink and coating compositions results in a reduction of migratable photodecomposition products that are produced by cleavage type photoinitiators during UV-cure. The ink and coating compositions are particularly useful for use in applications that require low migration of low molecular weight materials, such as, for example, food packaging.

Abstract: The present invention provides water-based ink and coating compositions having a high renewable resin content. The ink and coating compositions of the invention comprise equal to or greater than 65% (w/w) renewable resins, based on the total combined weight of the resins. Renewable resins derived from gum rosins are preferred. The ink and coating compositions of the present invention exhibit physical properties (e.g. adhesion and resistance) that are as good as, or better than, current commercially available inks (e.g. acrylic based inks not containing renewable material).
Abstract: The present invention is drawn to low migration energy-curable compositions including epoxy acrylates derived from the reaction of poly(alkylene oxide) containing glycidyl ethers with acrylic acid. The compositions of the invention are particularly useful for the printing or coating of food packaging.
Abstract: Described are primer coatings, overprint varnishes, and seaming solution solutions for application to substrates such as those used to make wrap around and sleeve labels, particularly shrink wrap labels, which are used to label containers. The labels can be digitally printed with or without lane priming. With certain seaming solutions, the labels can be removed in the wash stage to enable the recycling of containers.
