ABSTRACT:
A solvent system has been found which improves the blotting time smearfastness and smudge for ink-jet inks. Two solvents work in conjunction with each other: 2-methyl-1,3-propanediol and methyl pentanediol. These two solvents work in combination to improve printability of inks, especially pigment-bases inks that contain latex polymers. Such ink-jet inks also include typical vehicle adjuncts.
