An improved ink suitable for ink jet printing comprising, a mixture of a colorant, an arylketoalkene stabilizing compound or a photoreactor, and a liquid vehicle, wherein the colorant is light-stable. When the photoreactor is combined with a wavelength-selective sensitizer to form a radiation transorber, the colorant is mutable upon exposure of the radiation transorber to specific, narrow bandwidth radiation. The colored composition may also contain a molecular includant having a chemical structure which defines at least one cavity wherein each of the colorant and photoreactor or radiation transorber is associated with the molecular includant. The invention also includes ink jet print cartridges containing the improved ink, ink jet printers containing the improved ink and methods of printing using the improved ink.

Ink for ink jet printers

An ink composition for inkjet printing that in the printing by means of an inkjet printer, is free from nozzle clogging to thereby enable obtaining a print of desirable printing quality, and that can ensure appropriate drying rate for printing and further excels in color development. There is provided an ink composition for inkjet printing, comprising a pigment, a binder resin, a pigment dispersant and a solvent, wherein the solvent is composed of (1) at least one glycol ether and at least one of a lactone compound and 2-pyrrolidone, or (2) at least one glycol ether acetate and at least one of cyclohexanone and isophorone.

Ink composition for inkjet printing

An ink set includes a metallic ink composition containing a metal pigment and at least one curable ink composition selected from the group consisting of a chromatic ink composition, a black ink composition, and a white ink composition.

Ink set, ink-jet recording method, and recorded material

A method of forming an opaque layer includes forming a first layer by discharging droplets of an ink composition containing a metallic pigment on a record medium by an ink-jet recording process and forming a second layer by discharging droplets of an ink composition containing a white pigment on the record medium by an ink-jet recording process. The opaque layer is formed on the record medium on the side where the first layer and the second layer are formed in a region where the first layer and the second layer overlap each other.

A digital information recording media which includes a recording layer comprising a light-stable colored composition which composition is mutable or decolorizable upon exposure to a specific wavelength of ultraviolet radiation. The light-stable colored composition includes a colorant and an ultraviolet radiation transorber. The colorant, in the presence of the radiation transorber, is adapted, upon exposure of the transorber to specific, narrow bandwidth ultraviolet radiation, to be mutable. The radiation transorber also imparts light-stability to the colorant so that the colorant does not fade when exposed to sunlight or artificial light. The ultraviolet radiation transorber is adapted to absorb radiation and interact with the colorant to effect the irreversible mutation of the colorant. Especially useful radiation is incoherent, pulsed ultraviolet radiation produced by a dielectric barrier discharge excimer lamp or coherent, pulse radiation produced by an excimer laser. In another embodiment, the colored composition which comprises a colorant and an ultraviolet radiation transorber may also contain a molecular includant having a chemical structure which defines at least one cavity. Each of the colorant and radiation transorber is associated with the molecular includant. In some embodiments, the colorant is at least partially included within a cavity of the molecular includant and the ultraviolet radiation transorber is associated with the molecular includant outside of the cavity. In other embodiments, the radiation transorber is covalently coupled to the molecular includant.

Use of Pigment Yellow 155 in electrophotographic toners and developers, powder coatings and inkjet inks C.I. Pigment Yellow 155 is used as a colorant in electrophotographic toners and developers, powder coating materials, inkjet inks, color filters and electret materials.

Using pigment yellow 155 in electrophotographic toners and developers, powder coatings and inkjet inks

PROBLEM TO BE SOLVED: To obtain a green-yellow azo coloring agent which has a neutral triboelectric effect, good dispersibility and high thermal stability and which is highly transparent by using an azo pigment essentially comprising C.1 pigment yellow 155 as a coloring agent. SOLUTION: An azo pigment expressed by the formula is used as a coloring agent for an electrophotographic toner which is a liquid toner or powder toner or for a developer, developer powder,. powder coating material. electret material, color filter and ink-jet ink. The pigment having the structure of the formula is commercially available as C.I. pigment yellow 155. This pigment itself is improper for a polyester but shows extremely good properties such as extremely good dispensability and high transparency even in a toner resin essentially comprising a polyester. Moreover,. the pigment is superior in the neutral electrostatic effect. This pigment shows thermal stability at >300 deg.C.
