<p>PURPOSE: To obtain an emulsion ink for pore plate printing, capable of providing a printed image having a high concentration and fixed qualities, excellent in drying properties, free from ink bleeding, strike-through and offset irrespective of the kind of printing paper and the existence of unevenness on the surface of printing paper. CONSTITUTION: In a water-in-oil type emulsion ink containing an oil phase and a water phase, this emulsion ink for pore plate printing contains as extender pigment in the oil phase, where the amount of the extender pigment contained is 1-50wt.% based on that of the whole emulsion ink. A colorant, a resin, a nonvolatile solvent, a volatile solvent and an emulsifying agent are contained in the oil phase or the resin, the nonvolatile solvent, the volatile solvent and the emulsifying agent are contained in the liquid phase and the colorant, an oil-in-water type resin emulsion and/or a water-soluble polymer compound are contained in the water phase.</p> |
