摘要： A water-in-oil (W/O) emulsion ink which is suitable for use in inkjet printing and superior in ejection performance and storage stability is provided. A polyglycerin fatty acid ester which fatty acid moiety is oleic acid or isostearic acid and which has an HLB value of 7-14, is used as an emulsifier. The polyglycerin fatty acid ester preferably has a glycerin polymerization degree of 4-20 and preferably contains 1-3 fatty acids per one molecule thereof. The polyglycerin fatty acid ester has an organic value of preferably 550-2300 and an inorganic value of preferably 600-2500. Preferably, the emulsion ink comprises 40-99 mass % of the oil phase and 60-1 mass % of the water phase, and comprises 0.5-40 mass % of the polyglycerin fatty acid ester relative to the total amount of the ink. The water phase may contain a dye and optionally a solubilizer such as an amine based surfactant.

摘要： A water-in-oil (W/O) emulsion ink which is suitable for use in inkjet printing and is superior in ejection performance and storage stability and low in viscosity is provided. A water-in-oil (W/O) emulsion ink which comprises a polyglycerin with a polymerization degree of not less than 3 in a water phase is provided. As an emulsifier, a polyglycerin fatty acid ester with an HLB value of 7-14 in which fatty acid moiety is oleic acid or isostearic acid, or a polyoxyethylene sorbit fatty acid ester is preferably used. The concentration of the polyglycerin in the water phase is preferably 10-70 mass % relative to 100 mass % of the whole water phase. The polymerization degree of the polyglycerin is preferably not less than 4.
