Vanadium-drier intaglio ink

摘要

An oxidatively curing intaglio printing ink is disclosed, comprising an oxidatively curable polymer, an anionic macromolecular surfactant, a wax component, and a salt of vanadium, preferably of the vanadyl (VO2+) ion, as the oxypolymerization inducing siccativating agent.

主权项

1. Oxidatively curing oil-based printing ink composition for the engraved copper-plate intaglio printing process, comprising:
a vanadyl (VO2+) ion bound to an anionic macromolecular surfactant (AMS), wherein the AMS comprises at least two acid groups separated by at least one conjugated double bond; at least one oxidatively curable material; at least one wax component; and at least one pigment or filler, wherein said ink composition has a total viscosity of at least 3 Pa·s at 40° C. and a shear rate of 1000 s−1.
