    Abstract: Embodiments of the invention relate to ink compositions suitable for applications in the printing industry, for example continuous inkjet printing, including ultra-high speed continuous inkjet printing. The ink compositions use volatile organic solvents, a colorant, and one or more binder resins including a resin that is a phenolic resole resin, wherein the ink composition is free of methanol, halogens, halogenated compounds and bisphenol-A. A phenolic resole resin of the ink composition preferably contains less than 0.1% by weight of free formaldehyde. The one or more binder resins including the phenolic resole resin may be present in an amount that is from about 5% to about 30% by weight of the ink composition.

    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.

    Abstract: Embodiments of the invention relate to ink compositions suitable for applications in the printing industry, for example continuous inkjet printing, including ultra-high speed continuous inkjet printing. The ink compositions use volatile C5 ketone (pentanone) solvents (e.g., 2-pentanone, 3-pentanone, or 3-methyl-2-butanone) as a major solvent or the only solvent, and also include a binder resin and a colorant, but preferably contain substantially no acetone, methanol, or methyl ethyl ketone, or other solvents listed on the Japan ISHL class II organic solvents list. Preferred ink compositions can contain up to 30% ethanol, n-propanol, or other solvents not listed on the Japan ISHL class II organic solvents list, but preferably contain substantially no ethanol.
