However, some of these ink compositions are water-based compositions because they contain water-soluble quinone dyes (such as anthraquinone dyes) and thus exhibit long ink drying times

Abstract

Disclosed is a solvent-based ink composition, particularly an ink jet ink composition, comprising one or more organic solvents, one or more solvent-soluble binder resins, and a water- insoluble quinone dye, wherein the quinone dye is present in the ink composition in a dissolved state and the ink composition is a single phase ink composition. Also disclosed is a method of printing images on a substrate employing the ink composition.

Description

Background of the invention [0001] The present invention relates generally to ink compositions, and more particularly to inkjet ink compositions. Inkjet printing is a well known technique by which printing is done without contact between the printing device and the substrate on which the printed characters are deposited. Briefly, an inkjet printer involves ejecting a stream of ink droplets onto a surface and controlling (eg electronically controlling) the flow such that the droplets are caused to form the desired printed information on the surface. [0002] The technique of inkjet printing, or contactless printing, is particularly suitable for applying characters to irregularly shaped substrates or surfaces, including for example glass, metal or plastic containers commonly used to hold beverages, cosmetics, pharmaceuticals, liquids and healthcare products. [0003] Ejection of ink droplets can be done in several different ways. In the first process, called continuous inkjet ...
