<p><P>PROBLEM TO BE SOLVED: To provide an emulsion ink for stencil printing exhibiting good pigment dispersibility, causing no pigment aggregation on emulsifying and excellent in storage stability as an emulsion. <P>SOLUTION: The ink for stencil printing comprises a water-in-oil emulsion comprising 10-50 wt% of an oil phase and 90-50 wt% of an aqueous phase, where at least a copper phthalocyanine pigment treated with a specific copper phthalocyanine derivative is contained as a pigment in the oil phase. The treated copper phthalocyanine pigment is preferably contained in a concentration of at least 0.5 wt% based on the total amount of the ink. The copper phthalocyanine pigment is preferably treated with 0.01-50 wt%, preferably 2-20 wt%, based on the copper phthalocyanine pigment, of the specific copper phthalocyanine derivative. Preferably, the particle size of the primary particle of the copper phthalocyanine pigment is 40-360 nm. <P>COPYRIGHT: (C)2004,JPO</p> |
