  • Ink composition for a meltable ink
    Patent number: 6280510
    Abstract: An ink composition for a meltable ink usable in a printing apparatus in which ink droplets are ejected from ink ducts, the ink composition containing an amorphously solidifying monomer compound, which compound shows a crystallinity of less than 1% when a melt of the compound is cooled at a rate of 5° C./min to past its solidification path and is then heated at a rate of 20° C./min to above its melting temperature. The monomer compound can be used in a binder for the ink composition. When inks of this kind are transferred to a receiving material, it results in greater stability in the printed layers, with respect to gum, scratch, fold resistance and transparency.
