摘要： The present invention provides a jet ink composition suitable for application onto a substrate comprising an ink carrier, a colorant, a polyol, an aldehyde-based cross-linking agent, and a catalyst that promotes a reaction between the cross-linking agent, the polyol, and the substrate. Examples of preferred cross-linking agents are modified melamine formaldehyde resin and modified urea formaldehyde resin. The substrates preferably possess carboxyl, hydroxyl, amide, or sulfhydryl groups. An example of a preferred substrate is cellulose. The cross-linking reaction is carried out at relatively moderate temperatures and at high speeds. The printed image has excellent adhesion to substrates, abrasion resistance, crinkling resistance, water resistance, and heat resistance.

摘要： The present invention provides jet ink compositions that are free or substantially free of sedimentation, have good image adhesion and rub resistance, and that are suitable for printing messages on food items such as fruits, vegetables, chocolate, candies, confectioneries and pharmaceuticals such as tablets, and other edible or ingestible materials. The jet ink compositions comprise a surface modified or coated colorant. The surface modified or coated food grade colorant comprises a food grade colorant of particle size in the range of from about 0.01 micron to about 25 microns, a colorant carrier, and a surface modifying or coating agent. The surface modifying or coating agent comprises at least one binder resin, and preferably two or more binder resins.

摘要： The present invention provides an ink jet ink composition suitable for use in continuous ink jet printing comprising a liquid vehicle, a binder resin, a colorant, and optionally a surfactant. The liquid vehicle includes an organic solvent or blend of solvents having an evaporation rate less than about 1.2, relative to n-butyl acetate standard which has an evaporation rate of 1.0. The present invention further provides a method for eliminating or reducing make-up consumption in continuous ink jet printing. The present invention further provides a process of continuous ink jet printing which is free or substantially free of make-up consumption.

摘要： The present invention provides a jet ink composition comprising a volatile organic solvent, an oil, one or more binder resins which are soluble in the volatile organic solvent, and a colorant. The ink composition is fast drying and provides excellent adhesion to non-porous substrates. Printers, such as drop-on-demand ink jet printers, employing the ink composition can operate without nozzle clogging even after long non-printing intervals. The present invention further provides a method for reducing clogging of a nozzle orifice in an ink jet printer comprising printing with an ink composition that includes an oil that forms a continuous oil phase which acts as the boundary layer between the air outside the nozzle orifice and the ink inside the nozzle during non-printing intervals. The present invention further provides a process for jet ink printing onto a substrate comprising projecting a stream of ink droplets of the ink composition of the present invention to the substrate and controlling the direction of the droplets so that the droplets form the desired printed image on the substrate.
