  • Patent number: 5496879
    Abstract: A solid or amorphous printing ink, especially a gravure printing ink, is fused to become printable in a fluidized condition. The ink is fixed on imprint material by solidification by heat extraction or cooling. The ink includes a binder-material having at least two component groups with each having at least one member, of which members of the first component group have the property to act as solvent for the members of the second group of components. The members of the first component group are solid state crystalline materials. The materials are solid at ambient temperature with a relatively low melting point. The members of the second component group are in a vitreous solid or amorphous condition at ambient temperature. These materials, especially polymers, are soluble in the molten first component group.
