摘要： The invention provides a water based pigment ink composition comprising water, a pigment, a water-soluble resin, a phosphoric acid ester as a surfactant and an O/W type emulsion of at least one water-insoluble resin selected from the group consisting of acrylic resin, styrene resin and styrene/acrylic resin, wherein resin particles in the emulsion have an average particle diameter in the range of 50 to 200 nm, and the emulsion has a minimum film forming temperature of 50° C. or more. The water based pigment ink composition has excellent coloration in a common white paper and is excellent in the dispersion stability of a pigment and in storage stability, thus giving a handwriting at high density by use in a writing implement or an inkjet image at high density by use in an inkjet printer.
摘要翻译：本发明提供一种水性颜料墨水组合物，其包含水，颜料，水溶性树脂，作为表面活性剂的磷酸酯和至少一种选自丙烯酸类的水不溶性树脂的O / W型乳液树脂，苯乙烯树脂和苯乙烯/丙烯酸树脂，乳液中的树脂颗粒的平均粒径为50〜200nm，乳液的成膜温度为50℃以上。水性颜料墨水组合物在通常的白纸中具有优异的着色性，并且颜料的分散稳定性和储存稳定性优异，因此通过在书写工具或高密度下的喷墨图像中以高密度提供高密度的手写用于喷墨打印机。
