    摘要： A water-in-oil (W/O) emulsion ink for stencil printing is provided, which contains a water-insoluble colorant in the water phase, has the water phase dispersed finely and stably in the oil phase, and can provide prints high in printing density and glossiness. The water-insoluble colorant has an average particle size of 1 µm or less, and constituted by particles of 1 µm or less in particle size in amount of 50 % or more on area basis of the total of said water-insoluble colorant. The emulsion ink is preferably formed by use of an emulsifier having an HLB of 1.5 - 6.0, and preferably contains a tertiary amine compound in the water phase as a dispersant for the water-insoluble colorant.

    摘要： A water-in-oil (W/O) emulsion ink for stencil printing is provided, which is excellent in emulsion stability and drying, high in printing density and low in blurring and seep through. The W/O emulsion ink has an oil phase and a water phase, in which an acid anhydride containing water-soluble polymer is contained together with a water-insoluble colorant in said water phase. The acid anhydride containing water-soluble polymer is preferably an acid anhydride containing olefin copolymer, more specifically, an isobutylene-maleic anhydride copolymer, or an acid anhydride containing vinyl copolymer, more specifically, a styrene-maleic anhydride copolymer. Preferably, the oil phase comprises at least a solvent and an emulsifier, and the water phase comprises a water-in-oil (O/W) emulsion of resin and/or a water-soluble resin.
