Abstract: The invention relates to a high adhesion ink with good abrasion resistance, useful for inkjet printing. These inks include a first resin comprising a polymer comprising vinyl chloride or a polymer comprising vinyl acetate, the first resin having a weight average molecular weight between about 20 kDa and about 80 kDa, a second resin comprising a tackifier resin with a weight average molecular weight between about 200 Da and about 2.5 kDa, and a third resin with a weight average molecular weight between about 500 Da and about 40 kDa.

Abstract: The present invention relates to inkjet ink compositions that take advantage of solvent mixtures containing an ester, a ketone, and optionally an alcohol, in order to provide ink compositions that have suitable qualities for inkjet printing. Preferred ink compositions include a C1-C3 alkyl ester of C1-C3 carboxylic acid, a C3-C7 ketone, and optionally a C2-C3 alkyl alcohol.

Abstract: Embodiment of the present invention relate to a continuous inkjet ink composition which uses a higher order ketone solvent or solvents (ketones having 5 or more carbon atoms) in place or more hazardous solvents such as methyl ethyl ketone and a secondary solvent with a higher derived no effect inhalation level greater than 200 mg/m3 such as ethanol. These ink compositions contain a combination of resins including a cellulose resin and a polyurethane resin or an acrylic resin, with an optional third resin. A colorant (i.e., a dye, preferably a conductive dye) also is included.

Abstract: A thermal ink jet ink composition includes one or more volatile organic solvents, wherein the one or more volatile organic solvents comprise a solvent selected from C1-C4 alcohols, C3-C6 ketones, C3-C6 esters, C4-C8 ethers, and mixtures thereof. The one or more volatile organic solvents are present in an amount at least 60% by weight of the ink composition. The ink composition includes one or more binder resins present in an amount from 1% to 10% by weight of the ink composition, and one or more dyes. If water is present, it is present in amount less than 5% by weight of the ink composition. The ink composition includes less than 2% by weight of any humectant and/or wetting agent with a relative evaporation rate less than 0.3. The ink composition is suitable for use in a thermal ink jet printer.

Abstract: The present invention is a thermal inkjet ink that provides good reliability at a wide range of industrial print conditions from both low temperature to high temperature environments across a broad range of humidities. It is particularly advantageous in low-temperature applications, for example, printing at temperatures down to 5° C. or lower continuously for 8 hours without developing print defects which can lead to unreadable codes; and, in the meantime also maintains other critical functional aspects including contrast, wetting, decap time, dry time, adhesion, ink cartridge stability, etc. The inks contain one or more binder resins that exhibit a hydroxyl number or acid number of at least 100 mg KOH/g; one or more terpene phenolic resins; one or more volatile organic solvents; and one or more dyes, and optionally further components.
