AQUEOUS GRAVURE INK COMPOSITION KEEPING VISCOSITY OF INK DURING PAINT WORK

摘要

PURPOSE: Provided is an aqueous gravure ink composition which dissolves or dilutes negative ion water-dispersible urethane resin in water so that it possibly maintains proper mobility and viscosity in the ink composition. CONSTITUTION: The aqueous gravure ink composition comprises the components of: by 100wt% of gravure ink composition, 15-20wt% of paint; 12-40wt% of negative ion water-dispersible urethane resin which is desirably 200,000-300,000 in average molecule amount; water; alcohols like ethanol, isopropyl alcohol or so on which relatively reduce content of water in the entire composition to increase adhesion power with the painted subject; and other auxiliary agents.
