SOLUTION: This W/O emulsion ink contains a yellow pigment, an aluminum chelate compound, a polyglycerin fatty acid ester in an amount of 0.1-4 wt.% of the yellow pigment, and a nonvolatile mineral oil of which the carbon content based on its paraffin component is 60% or higher and the carbon content based on its naphthene component is 35% or lower.</p> |
