ABSTRACT:
A polyamide resin useful in the preparation of hot-melt inks for ink-jet printing is prepared by the condensation polymerization reaction of a monoamine, a diacid and a third reactant selected from diamines, aminoalcohols and blends thereof. Preferably, the diacid, monoamine and third reactant are reacted together in mole ratios of 2:2:1. The polyamides afford the ink compositions with a low viscosity at the elevated operating temperatures of an ink-jet printer, yet are solid at room temperature and contribute good adhesion to the printed substrate.
