<p><P>PROBLEM TO BE SOLVED: To provide an emulsion ink for stencil printing, which is excellent in prevention of oil separation over time, covering power and emulsion stability, even when titanium oxide is used as a pigment. <P>SOLUTION: The emulsion ink for stencil printing comprises 10 to 90 mass% oil phase and 90 to 10 mass% aqueous phase, wherein the oil phase contains titanium oxide with an average particle size of≥0.2μm and at least one chosen from titanium oxide with an average particle size of≤0.05μm and an extender. Preferably, the mixing ratio (titanium oxide A:titanium oxide B) of the titanium oxide (titanium oxide A) with an average particle size of≥0.2μm and the titanium oxide (titanium oxide B) with an average particle size of≤0.05μm is from 1:5 to 1:1, calculated in terms of a specific surface area, and the extender is calcium carbonate. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
