ABSTRACT:
A hot-melt ink for an ink jet printer is formed from a solid organic solvent having a melting point less than 150.degree. C. and a low molecular weight thermosetting resin having a high hydroxyl number, together with a dye. The ink has excellent jetting characteristics, forms a hard, stable print raised above the surface of the substrate, provides high dot resolution, and remains colorfast both in the ink jet printer and on the paper, even when exposed to continued high temperatures. It is non-toxic and odorless, and eminently suitable for office document preparation and other applications. In a preferred embodiment, the inks comprise color subtractive dyes, making them suitable for use in multi-color printing.
