<p>PURPOSE:To obtain the ink, improved in emulsion stability, ink drying properties and ink suitability to temperatures, having a high printing density of prints, hardly causing bleeding and strike through properties and useful for stencil printing by dispersing a water-insoluble colorant in an aqueous phase with a specific compound. CONSTITUTION:This ink is obtained by dispersing (A) a water-insoluble colorant in an aqueous phase with (B) a tertiary amine compound in a W/O type emulsion ink having an oily phase and the aqueous phase. Furthermore. the average particle diameter of the component (A) is preferably <=10mum and, e.g. a compound having one bond of formula I in the molecule, specifically polyvinylpyrrolidone, etc., of formula II are preferably used as the component (B).</p> |
