An ink for ink-jet recording is provided in which copper phthalocyanine dyes and a thiazole-based compound are used. In this ink, the mildew resistant properties are not impaired, and the ink exhibits excellent ozone resistance. Furthermore, the formation of a precipitate is prevented in the ink although the thiazole-based compound is used. In the ink for ink-jet recording, as copper phthalocyanine dyes, two types of dyes are used together with a thiazole-based compound. Furthermore, about 1 mol...

An ink cartridge comprises a box containing a plastic bag or bladder which is manufactured, filled and sealed in the controlled environment of a factory. As manufactured, the bladder has almost no chance of any substantial amount of air being entrapped therein. It has no openings, except for a small fill opening which is sealed immediately after the bladder is filled with ink. The bladder has rounded contours to prevent entrapment of gas and foreign substances. A plastic tube is welded to the ou...

Disclosed is an aqueous ink composition useful for ink jet printing, which comprises 2-12 wt % of a water soluble dye, 35-80 wt % of a polyhydric alcohol having 2-6 carbon atoms.

An ink system, especially for use in retort environments, is disclosed. The ink system comprises a hard polyester resin, a soft polyester resin, a polyisocyanate catalyst and an appropriate pigment or pigments.

The invention relates to a printing ink formulation for producing a transferable layer comprising a pigmentary material or a material possessing predetermined electrical properties, a hot melt adhesive, a solid phase plasticizer and a solvent.

This invention relates to a radiation curable decorating ink comprising: at least one acrylic monomer or oligomer; at least one photoreactive resin; at least one photoinitiator; at least one free radical inhibitor; and at least one pigment. This invention also relates to novel photoreactive resins.

A news ink of low misting properties comprising a dispersion of a news ink pigment in a hydrocarbon oil, wherein the oil has the following physical properties: Color: water white Aromatic content: zero Refractive index: 1.467-1.480 Specific gravity: 0.850-0.879 Viscosity, cSt/40.degree.

A dispersion ink for ink jet printing and which is stable and produces good quality print on plain paper for extended periods of time without the need to interrupt printing to clean the print head, comprises a diluent containing a non-polar component, a pigment and a dispersant for stabilizing the dispersion of the pigment in the diluent, and has a polar solubility parameter greater than 0 but not greater than 7.0 MPa.sup.1/2 and a dewetting velocity of at least 100 .mu.m.sec.sup.-1, measured on...

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 struct...
