ABSTRACT:
There is provided a water-in-oil (W/O) emulsion ink for stencil printing having an oil phase and a water phase, the oil phase containing a reaction product of an alkyd resin or a rosin-modified resin with an aluminum chelate compound or an aluminum alcoholate. Preferably, the reaction is carried out by heating the aluminum chelate compound or aluminum alcoholate with the alkyd resin or rosin-modified resin to a temperature enough to lower the acid value of the resin to 10 or less, and the reaction is carried out in the presence of a higher fatty acid or a higher alcohol in an amount of 0.5-2.5 mols per 1 mol of on the aluminum chelate compound or aluminum alcoholate. This emulsion ink is improved in storage stability and inhibited from increase of viscosity of the ink after the ink is left, and restarting of printing after suspension of operation of the printing machine can be satisfactorily performed.
