Patent ID: 8349917

Claim:
A printing ink consisting essentially of: a) from 15 to 45 weight percent of finely subdivided resin particles selected from the class consisting of particles of high and ultra high molecular weight polyethylene having a density from 0.94 to 0.97 gm/cc., alone or in admixture with particles of polyethylene having a density from 0.91 to 0.94 gm/cc. and particles of polypropylene having a density greater than 0.9 gm/cc., said resin particles having a size from 1 nanometer to 150 microns; b) from 15 to 45 weight percent of a hydrocarbon solvent selected from the class consisting of aliphatic and aromatic hydrocarbons and having sufficient volatility for substantially total removal at a temperature from 300 F. to 500 F.; c) from 0.05 to 2.0 weight percent of a dispersant, sufficient to stabilize the dispersion of the resin particles in the hydrocarbon solvent; and d) from 1 to 70 weight percent of an additive selected from the class consisting essentially of a colorant, metallic particles, mineral particles and mixtures thereof.
