<p>PURPOSE: To obtain the subject ink for stencil printing, comprising water-in-oil type emulsion, excellent in dryness in touching and capable of providing at a relatively low cost by adding an oil-in-water type resin emulsion in a specific amount as a solid content based on total amount of ink to a water phase. CONSTITUTION: This emulsion ink for stencil printing excellent in dryness in touching is obtained at a relatively low cost by uniformly mixing a coloring agent such as carbon black, a solvent such as spindle oil, a pigment dispersing agent such as aluminum chelate, an emulsifier such as sorbitane sesquioleate, an antifreezing agent such as ethylene glycol and an electrolyte such as magnesium sulfate with deionized water in a water-in-oil type emulsion consisting of about 10-90wt.% oil phase and about 90-10wt.% water phase to prepare ink composition and adding an oil-in-water type resin emulsion of a styrene/ acrylic acid ester in an amount of 0.1-1.8wt.% (as solid content) based on total amount of ink as the oil-in-water type resin emulsion to the composition.</p> |
