    • An aqueous ink composition comprising: a pigment, having a particle diameter as determined by the light scattering method of no less than 20 nm and no more than 200 nm; and a water dispersible polymer, having a styrene-equivalent number average molecular weight of as determined by gel permeation chromatography no less than 5000 and no more than 200000, having a surface tension of no less than 20 mN/m and no more than 40 mN/m, and wherein the abovementioned pigment is a polymer-coated pigment that is coated with the abovementioned water dispersible polymer, is provided. The water-dispersible polymer may be a copolymer of monomers, mainly comprising acrylic acid and/or methacrylic acid and an acrylate and/or methacrylate. With this ink composition, the printing quality can be improved.
    • 一种水性墨水组合物,其特征在于,含有:通过光散射法测定的粒径不小于20nm且不大于200nm的颜料; 和水分散性聚合物,其具有通过凝胶渗透色谱法测定的苯乙烯当量数均分子量不小于5000且不大于200000,表面张力不小于20mN / m且不大于40mN / m,并且其中上述颜料是涂覆有上述水分散性聚合物的聚合物涂覆的颜料。 水分散性聚合物可以是主要包含丙烯酸和/或甲基丙烯酸和丙烯酸酯和/或甲基丙烯酸酯的单体的共聚物。 利用这种油墨组合物,可以提高打印质量。
