<p>PURPOSE: To obtain an emulsion ink for porous printing which does not suffer from leakage from the margin of paper for porous printing and retardation of the rate of penetration into the substrate. CONSTITUTION: This ink is a W/O emulsion ink composed of an oil phase component and a water phase component, and water-dispersible microparticles showing dilatancy are contained in the water phase component. Alternatively, this ink is one having a weight ratio of the oil phase component to the water phase component of (10-50)/(90-50) by weight, and 0.01-50wt.% water-dispersible microparticles exhibiting dilatancy are contained in the water phase component.</p> |
