Abstract

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.

Description

Background technique [0001] Thermal inkjet (TIJ) heads produce ink droplets by thermally vaporizing ink solvents. During spraying, the resistors are heated rapidly to create vapor bubbles, which then eject liquid droplets from the nozzle. This process is extremely efficient and repeatable. Modern TIJ nozzles for industrial graphics are capable of producing uniform droplets with volumes of 4pL or less at frequencies of 36KHz or greater. Typical commercial TIJ devices are specifically designed to vaporize water or solvents with physical properties close to water (eg, high boiling point, large heat capacity, low molecular weight). [0002] Although TIJ printing systems have been available for more than 30 years, almost all commercial inks used in thermal inkjet systems are water-based, i.e. they contain more than 50% water. Such aqueous inks suffer from one or more drawbacks, such as long ink drying times or poor adhesion to semi-porous or non-porous substrates. [0003] Inks...
