Provided is an ink set including at least two inks each including a coloring material, an organic solvent, and water, wherein a proportion of the organic solvent in each of the inks is 30 percent by mass or greater, wherein a relative mobility difference (maximum relative mobility−minimum relative mobility) between a maximum relative mobility and a minimum relative mobility among relative mobilities of the coloring materials included in the inks is 0.1 or greater, where the relative mobilities are obtained by thin-layer chromatography in which the coloring materials are developed using the organic solvents included in the inks as developing solvents.
提供了一种油墨组,包括至少两种油墨,每种油墨包括着色材料、有机溶剂和
水,其中有机溶剂在每种油墨中所占的比例为 30% 或更大,其中油墨中所含着色材料的相对迁移率的最大相对迁移率和最小相对迁移率之间的相对迁移率差(最大相对迁移率-最小相对迁移率)为 0.1 或更大,其中相对迁移率是通过薄层色谱法获得的,在薄层色谱法中,着色材料使用油墨中的有机溶剂作为显影溶剂进行显影。
