Abstract
An ink composition for jet printing onto non-porous-non-absorbent surfaces based upon a ketone solvent having a soluble ionizable salt and a dyestuff and which may contain in addition water in an amount up to 10% by weight, a lower alcohol in an amount up to 8% by weight, a pyrrolidone in an amount up to 4% by weight, a carbitol in an amount up to 4% by weight and a vinyl acetate copolymer resinous binder in an amount up to 6% by weight, the jet printing ink composition having a viscosity within the range of 1.5 to 10 cps, a resistance less than 2000 ohm-cm, a surface tension less than 28 dyne/cm, a velocity of sound within the range of 1200-1700 m/sec, and an upper limit of 5 microns and preferably 2 microns insolubles.
