<p><P>PROBLEM TO BE SOLVED: To provide water-in-oil type emulsion ink for stencil printing excellent both in storage stability of ink (prevention of formation of crystals in ink) and prevention of clogging of a screen (the master version) during printing. <P>SOLUTION: The emulsion ink for stencil printing comprises water-in-oil type emulsion ink comprising an oil phase containing a red pigment and an aqueous phase, wherein a chelating agent is included in the aqueous phase. The red pigment is a soluble azo pigment prepared by forming a metal salt of a water-soluble dye, thereby insolubilizing (laking) the same. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
