Abstract
A printing ink for inkjet printing for improving the durability and image quality of an inkjet image including: a) a liquid carrier; b) ionic dye molecules with surface charge dissolved in the liquid carrier; and c) plate-like nanoparticles having parallel main surfaces, and minor edge surfaces, dispersed in the liquid carrier, with the main surfaces of the nanoparticles having a same sign of surface charge as the ionic dye molecule. Durability and image quality of an inkjet image is improved using the inventive ink, while also enabling a stable, printable formulation that does not require milling of the ink colorant.
