A reactive ink for printing. A reagent in the ink reacts with a second reagent. A resultant product of the reaction of said first reagent with said second reagent is a polymeric material that is present on the substrate. A heat activated colorant or colorants, such as a sublimation dyes, are applied to the substrate. The heat activated dye has an affinity for the polymeric material, and the heat activated dye binds to the polymeric material upon heat activation of said heat activated dye.

Printing process and ink for heat activated colorants

Reactive inks and methods of generating an image on a substrate using both reactive and heat activated inks are presented. An image is printed on a substrate, without reacting the reagents in the ink. Subsequently, the reagents are reacted to fix the image to a substrate, with substantial permanency and fastness. Sublimation or similar heat activated dyes are printed are also printed on the substrate. The sublimation or similar heat activated dyes are activated, and have an affinity for polymer that is applied to the substrate.

Heat activated printing process

Energy activated printing process

A transfer medium is provided for receiving images formed on the medium by inks or toners comprising thermally diffusible colorants, including disperse dye and sublimation dye, and methods of using the medium to present images on substrates. The medium provides an opaque layer that allows transfer of the image from the medium to a substrate, and provides a background for the image when the image is transferred to a dark colored substrate, so that the dark colored substrate does not obscure the image.

Image receiver media and printing process

A process for printing images by means of an electrographic or electrostatic device using a toner that is cured by multiple applications of energy. The toner has energy-activated reactive components such as radiation-curable sites and reactive functional groups. An image is formed on a substrate by the toner without materially activating the reactive components. The reactive components are subsequently activated by applying a first energy source to adhere the image to the substrate by cross-linking and bonding the image permanently to the substrate, or by transferring the image to a second substrate. A second energy source is applied simultaneously with, or subsequently to, the first energy source, to promote cohesive strength of the image by cross-linking within the toner particles that form the image. The resulting image is permanently bonded to the substrate, yielding substantially enhanced image durability and fastnesses.

Energy activated electrographic printing process

This invention relates to an improvement in the art of making high pressure laminated materials utilizing saturating kraft paper. More particularly, the invention relates to release sheets coated with an aqueous polymeric composition which makes the sheets useful in the production of heat and pressure consolidated laminated materials. Papers which are coated with these aqueous polymeric compositions exhibit excellent release properties which, when employed as release sheets, permit high pressure laminates to be easily separated.

Method for releasing laminated materials

This invention relates to waterborne polymer compositions and their applications. More particularly, the invention relates to the utilization of water-dispersible polymers and fatty acid as surface-active agents in emulsion polymerization reactions to produce waterborne polymer compositions which exhibit superior grease, water, and chemical resistance properties.

Waterborne polymer compositions

This invention relates to ovenable and dual-ovenable coated paperboard suitable for use in producing food trays. More particularly, the invention relates to paperboard substrates which have been coated with a water-based release coating composition. Food trays made from such paperboard have superior grease resistance, high temperature resistance, and excellent food release properties&mdash;characteristics which make these trays particularly suitable for use in baking applications.
