摘要:
A thermal ink jet ink composition include a volatile organic solvent, a binder resin, a dye, a humectant in an amount less than 40% by weight of the thermal ink jet ink composition, and an additive for extending the decap time. The additive is present in an amount greater than 0.1% by weight of the thermal ink jet ink composition. The additive is selected from plasticizers, surfactants, aliphatic hydrocarbons, drying oils and mixtures thereof. The additive does not phase separate from the ink jet composition during application of the ink to a substrate in thermal ink jet printing.

摘要:
An inkjet printing system includes a print head in fluid communication with an ink reservoir and having a plurality of orifices and a corresponding plurality of associated ejection chambers. The print head includes a substrate and a barrier layer disposed on the substrate. The barrier layer defines in part a plurality of fluid channels and the plurality of ejection chambers. The barrier layer includes a material selected from epoxy-based photo resist materials and methyl methacrylate-based photo resist materials. An orifice plate is disposed over the substrate. The orifice plate includes the plurality of orifices in fluid communication with the ejection chambers. The orifice plate comprises a material selected from polyimides and nickel.
摘要:
Disclosed are ink jet ink compositions suitable for use in thermal ink jet printers. The ink jet ink compositions contain one or more volatile organic solvents, one or more humectants, one or more binder resins, and one or more colorants. The ink jet ink compositions may also contain additives such as a plasticizer and/or a surfactant. Embodiments of the ink jet ink compositions have short dry times, good adhesion to a variety of substrates, and/or long decap times.
摘要:
A thermal ink jet ink composition includes one or more volatile organic solvents, one or more solvent dyes, and one or more humectants. The one or more volatile organic solvents are selected from C1-C4 alcohols, C4-C8 ethers, C3-C6 ketones, C3-C6 esters, and mixtures thereof. The one or more solvent dyes are soluble in the organic solvent or solvents with a solubility of at least 0.1% by weight. The thermal ink jet ink composition is free or substantially free of tetrahydrofuran, binder resin, and water.

A thermal ink jet ink composition includes one or more volatile organic solvents, wherein the one or more volatile organic solvents are selected from C1-C4 alcohols, C3-C6 ketones, C3-C6 esters, C4-C8 ethers, and mixtures thereof; one or more humectants, wherein the humectants are present in an amount not more than 30% by weight of the ink composition; one or more binder resins; and one or more dyes. The ink composition is suitable for use in a thermal ink jet printer and the ink composition has a slow rate of kogation such that it is capable of being printed at least 10 million drops per nozzle from the thermal ink jet printer before drop weight of the ink composition is reduced by more than 10%.
摘要:
A method of preparing an inkjet printing system with a print head in fluid communication with an ink reservoir and having a plurality of orifices and a corresponding plurality of associated ejection chambers includes providing a substrate and disposing a photoresist material on the substrate. A mask is provided between the UV light source and the photoresist material. The photoresist material is exposed to the UV light source to polymerize the photoresist material to form a barrier layer on the substrate. The barrier layer defines in part a plurality of fluid channels and the plurality of ejection chambers. An orifice plate is attached over the substrate. The orifice plate includes a plurality of orifices in fluid communication with the ejection chambers.
摘要:
A solvent-based inkjet ink composition for inkjet printing includes at least 50 weight percent solvent, a colorant, a humectant, from 0.3 weight % to 8 weight % of a binder resin, and not more than 5 weight percent water. The ink composition is compatible with components of a thermal ink jet printer.
