ABSTRACT:
Ink compositions are provided which are suitable for use in ink jet printing on coated or uncoated substrates to form images which are highly resistant to abrasion and highly penetrant by virtue of the penetrating characteristics of a select solvent system. The ink compositions have improved handling safety and performance characteristics, and contain, in a preferred embodiment a penetrating solvent blend comprised of from about 50 to 90% n-propyl acetate as a major solvent, methyl cellosolve as a high boiling secondary solvent, and, as an auxiliary solvent a lower aliphatic alcohol; from about 3 to 25% by weight of a low molecular weight B or C-stage, modified phenol polymers; a colorant; an electrolyte; and optionally, a surfactant.
