A method of jet ink printing to produce opaque images including jet ink printing a surface with a nonaqueous jet ink composition, and subsequently contacting the surface with a resin opacifying solvent before the ink composition has dried, to separate the solvent in the ink composition from the solids therein and render the image opaque. The surface which is to be printed on may be wetted with a resin opacifying solvent before printing or may be dry.

Opaque jet ink printing method and composition

Ink compositions suitable for ink jet printing on metal, plastic, or paper surfaces, the ink characterized by light fast properties, incorporating in solution, silver nitrate and at least one solvent, said inks are subsequently exposed to ordinary light so as to render them particularly as a means for marking various materials whereby marking is normally visible.

Light sensitive jet inks

An ink composition for use in jet printing comprising an aqueous solution of a water-soluble dye and a humectant consisting of at least one member of the group consisting of organic phosphonates and organic phosphites.

Jet ink process

Light sensitive ink compositions suitable for ink jet printing on metal, plastic, or paper surfaces, the ink characterized by opaque properties in light, incorporating in solution, at least one diazo derivative and at least one solvent. According to another of its aspects, this invention is a process for information recording comprising producing a fine jet of liquid containing at least one diazo derivative, directing said jet of liquid onto a recording medium, modulating the density of said applied jet by an electric field in accordance with the information to be recorded, thereby recording said information, and thereafter applying ultraviolet light to said recording medium bearing said recorded information, thereby rendering said recording opaque.

Ink compositions suitable for ink jet printing on metal, plastic, or paper surfaces, the ink characterized by fluorescent properties in ultraviolet light, incorporating, in solution, a resin component, at least one solvent, proportioned to give the ink properties of heat and steam resistance, said inks are colorless in ordinary light and distinctly fluorescent in ultraviolet light so as to render them particularly suitable as a means for marking various materials whereby marking is normally invisible but easily detectable when subjected to ultraviolet illumination. According to another of its aspects, this invention is a process for information recording comprising producing a fine jet of liquid, directing a jet of colorless liquid onto a recording medium modulating the density of the applied jet by an electric field in accordance with the information to be recorded, thereby recording said information.

Jet ink process and ink composition fluorescent in ultraviolet light

In accordance with certain of its aspects, this invention relates to novel compositions and to the process for the plating of substrates by the jet printing of a metal or alloy which comprises continuously imprinting minute uniform droplets of a jet printing ink containing at least one soluble salt of at least one plate metal which is more noble than said basis metal, said jet printing ink exhibiting a viscosity at 68.degree. F. of between about 1.5 and 16 cps., said ink having a pH of between 0.5 and 9.5 and a specific resistivity of less than 10,000 ohm cm., onto a substrate, said droplets emitting from at least one ink jet electromagnetically energized to emit said droplets of ink at a rate of 8 to 150 kilohertz.

Plating of substrates by jet printing

Ink compositions suitable for ink jet printing on metal, plastic, or paper surfaces, the ink characterized by opaque and visible properties in light, incorporating, in solution, a resin component, and at least one solvent, proportioned to give the ink as deposited a high degree of tackiness. The printing bears an overlying coating of at least one pigment. According to another of its aspects, this invention is a process for information recording comprising producing a fine jet of liquid, directing the jet of liquid onto a recording medium while modulating the density of the applied jet by an electric field in accordance with the information to be recorded, thereby recording said information, affixing pigments to said recorded information, thereby rendering said information opaque and visible.
