摘要

PROBLEM TO BE SOLVED: To provide a method for producing water-in-oil emulsion ink for stencil printing and water-in-oil emulsion ink for stencil printing which has such fixing strength on paper as to retain the color under friction and which early achieves dryness on paper.;SOLUTION: The method for producing a water-in-oil emulsion ink for stencil printing containing 10-90 mass% of an oil phase and 90-10 mass% of a water phase and containing an aluminum chelate, a resin, a higher fatty acid and a colorant includes: a dispersion step of dispersing the aluminum chelate, the resin and the colorant in the oil phase; a dilution step of diluting the oil phase; and an emulsification step of mixing and emulsifying the oil phase and the water phase, wherein the higher fatty acid is mixed in the oil phase at least after the dispersion step and before the emulsification step.;COPYRIGHT: (C)2010,JPO&INPIT
