<p>PROBLEM TO BE SOLVED: To obtain a water-in-oil type emulsion ink for stencil printing, having slight temperature dependence, slight separation and change in viscosity and excellent storage stability in a stencil printer. SOLUTION: This water-in-oil type emulsion ink for stencil printing is characterized in that the ink is constituted of 10-90 wt.% of an oil phase and 90-10 wt.% of a water phase and comprises a nonvolatile naphthenic mineral oil having a carbon content of naphthene component of >=40% CN and a carbon content of paraffin component of <60% CP in a carbon distribution by a ring analysis and a nonvolatile paraffinic mineral oil having a carbon content of naphthene component of <40% CN and a carbon content of paraffin component of >=60% CP in a carbon distribution by the ring analysis.</p> |
