Abstract
A formulation and method of printing an ink or meltable ink layer having reactive dyes or mixtures of reactive dyes and disperse dyes as colorants. The ink or ink melt layer also includes an alkaline substance, a binder, and optionally, a heat-activated printing additive. Permanently bonded color images are provided by the reaction between the reactive dye and the final substrate, which may be any cellulosic, protein, or polyamide fiber material, or mixtures with polyester. Reaction occurs upon heat activation of the printed ink image.
