<p>Disclosed is an aqueous jet ink composition suitable for printing scratch and rub resistant identifying marks on substrates such as paper, glass, metal, or plastic substrates comprising water, a colorant, a binder resin, and a wax. An example of the colorant is carbon black. An example of the binder resin is a styrene-acrylic copolymer. An example of a suitable wax is a polyethylene or a polytetrafluoroethylene wax. The jet ink composition may further contain organic solvents, defoamers, conductivity agents, and biocides. Also disclosed are a process for preparing the jet ink composition and a process for producing identifying marks on the substrates.</p> |
