Abstract
Impulse-type ink jet ink compositions and processes for recording information therewith are provided. The ink compositions dry to the touch more rapidly than the impulse-type inks known in the art. The rapid-drying characteristics are believed to be attributable to their relatively low viscosities. The ink compositions preferably comprise from about 80 to about 99 percent by weight of a liquid vehicle which consists essentially of an organic solvent having a viscosity less than about 7.0 centipoise at 20.degree. C. and from about 1 to about 15 percent by weight of a colorant. The ink compositions are suitable for printing alphanumeric text or bar codes on highly calendared paper or other non-absorbent surfaces.
