The present invention provides n aqueous ink composition comprising a coloring component, an acetylene glycol-based surfactant, water, and a urea derivative, wherein the coloring component is a dispersion substance in which a colorant is enclosed with a dispersing polymer thereby being rendered dispersible in water, wherein the dispersing polymer comprises a hydrophobic part and a hydrophilic part, wherein at least a part of the hydrophilic part is a neutralized group obtained by neutralizing an unneutralized group constituting a part of the hydrophilic part, and wherein the neutralized groups are present within an amount range of from 20% to less than 60% in terms of molar ratio based on the sum of the neutralized groups and the unneutralized groups.
本发明提供了一种包括着色组分、基于乙炔二醇的表面活性剂、水和脲衍生物的水性油墨组合物,其中着色组分是一种分散物质,其中颜料与分散聚合物一起封闭,从而使其能够在水中分散,其中分散聚合物包括疏水部分和亲水部分,其中至少部分亲水部分是通过中和构成亲水部分的未中和基团而获得的中和基团,其中中和基团在摩尔比例上基于中和基团和未中和基团的总和而在20%到小于60%的范围内存在。
