Abstract
An ink and method of its use for printing on a variety of substrates in a first aspect involves a water-insoluble colorant, water, and a primary solvent such as diacetone alcohol capable of dissolving both the water-insoluble colorant and the water. In a further aspect, the ink composition includes a secondary solvent capable of modifying the properties of the ink, the secondary solvent being selected from the group consisting of alcohols, amines, esters, glycol ethers, ketones, polyols, and keto-pyrroles. In a still further aspect, the ink may have at least two polyols, including a first polyol characterized by being semi-solid at operating temperature and a second polyol characterized by being liquid at operating temperature. In a further aspect, the ink composition includes a surfactant selected from the group consisting of hydrocarbon-based surfactants, silicone-based surfactants, and fluorosurfactants.
