| abstract |
A hot-melt subtractive ink for an ink jet printer is formed from a thermosetting resin having a high hydroxyl number and a solid organic solvent having a melting point less than 150 °C, 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 though exposed to continued high temperature. It is non-toxic and odorless, and eminently suitable for office document preparation, among other applications. |
