Abstract
Abstract Printing inks comprising an oxidation polymerization type resin, at least a part of which sets to gel in a non-polar ink solvent, a color agent, and an ink solvent, at least a part of which being a non-volatile polar solvent. When the printing ink is applied onto an absorbent printing object, the non-volatile polar solvent is easily absorbed by the printing object to gel the oxidation polymerization type resin, thereby to allow the ink to dry quickly, whereas the ink on non-absorbent printing members of a printing machine does not dry easily.

A printing ink for offset printing comprising an oxidation polymerization resin, a coloring agent, and an ink solvent, at least a part of said oxidation polymerization resin being an amine-denatured resin which sets to a gel in a non-polar ink solvent, and at least a part of said ink solvent being a non-volatile polar solvent.
Claim 3
Dependent Claim
