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.

An ink composition for a meltable ink usable in a printing apparatus which comprises an ink containing an amorphously solidifying monomer compound, having 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 point and is then heated at a rate of 20° C./min to above its melting temperature.
An ink composition for a meltable ink, which comprises an ink containing
- a meltable base material,
- an amorphously solidifying monomer compound having 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, and
- an amorphous polymer or oligomer binder,
- said base material being a crystalline-solidifying monomer compound.
