ABSTRACT:
Binderless ink compositions suitable for use in jet printing operations on polymeric resin surfaces to form images which are highly resistant to abrasion and to steam pasteurization conditions by virtue of penetration of the colorant into the sub-surface structure of the resin, in contrast to conventional ink images secured on the surface of a substrate by binders incorporated in the ink composition. The preferred inks contain a basic or neutral dye, a water and alcohol solvent system, a surfactant, an aliphatic ketone or ester and, as a preferred optional agreement, an aliphatic hydrocarbon of 8-12 carbons.
