An ink jet textile-printing ink composition according to the present disclosure contains an acidic dye having water solubility of 30 g/L or less at 20° C., a water-soluble organic solvent, and water, wherein a glycol-based solvent and a cyclic-amide-based solvent are contained as the water-soluble organic solvent, and the cyclic-amide-based solvent contains one or both of ε-caprolactam and N-hydroxyethyl-2-pyrrolidone.

Provided is a curable ink composition, in particular a curable inkjet ink composition. The ink composition has a dye monomer, a carrier monomer and an initiator. The dye monomer has a chromophore moiety that is covalently bonded to at least one polymerizable functional group and is present at 1.0 wt % or more based on total weight of the ink composition. The carrier monomer has at least one polymerizable functional group and is present in at 50 wt % or more based on total weight of the ink composition. The ink compositions are suitable for radiation curing such as UV curing and have good cure properties or light fastness properties.

Described herein are adhesive gold inks, and methods for making and depositing these inks to form conductive traces. The adhesive gold inks generally contain a gold complex dissolved in a mixed solvent system including at least a diol and an amine. The mixed solvent system may further include a thioalkyldiol. The gold complex includes a first ligand and a second ligand. The first ligand may be a thioether, a phosphine, or an amine that volatilizes upon heating at a temperature of 200° C. or less. The second ligand may be a halide or a carboxylate. The adhesive gold inks are clear and particle-free and may be formulated for deposition by a wide range of printing methods on both flexible and non-flexible substrates.
