摘要： The invention provides an aqueous pigment ink composition that ensures excellent recording characteristics on any type of recording mediums. An aqueous pigment ink composition of the invention includes a pigment, a water-dispersible polymer, water, and a water-soluble organic solvent, where the pigment is dispersed as primary particles having an average primary particle diameter of not greater than 50 nm and as secondary particles having a ratio of an average secondary particle diameter to the average primary particle diameter in a range of 1 to 10, and the water-dispersible polymer has a minimum glass transition temperature of lower than 100° C. Using this polymer ensures good dispersion stability and favorable glossiness on a glossy medium.

摘要： This invention provides an water-base ink achieving high print quality on plain, recycled, and coated paper, glossiness on glossy paper, as well as well-balanced gas fastness, and an water-base ink set which exhibits low light source dependence with regard to the colors of resultant printed matter. This invention is an water-base ink comprising a pigment, a surfactant and/or a penetrating organic solvent, and water, wherein the pigment is a copper phthalocyanine pigment substituted with eight or less chlorine atoms; the surfactant is an acetylene glycol surfactant and/or an acetylene alcohol type surfactant; and the penetrating organic solvent is one or more selected from the group consisting of di(tri)ethylene glycol monobutyl ether and/or (di)propylene glycol monobutyl ether, and 1,2-allylene glycol. This invention is also an water-base ink set comprising the water-base ink, a magenta ink and a yellow ink.
