Abstract
A latent ink which includes a liquid carrier, a latent image forming material as the coloring component, a thickening, film forming agent, and a liquid humectant. The thickening, film forming agent is used to adjust the viscosity of the ink as well as provides for the formation of a thin, clear film of uniformly dispersed latent image forming material when the ink is applied to a substrate. The humectant prevents the thickening, film forming agent from becoming brittle when applied to the substrate.
