PROBLEM TO BE SOLVED: To provide an ink set expressing a sharp edge in high color concentration, giving no irregular line thickenings in the pictures and generating no boundary bleedings in the pictures when adjacently printed with different color inks and capable of forming clear color pictures, even a recording paper having a high degree of sizing is used in recording the color pictures by an ink jet. SOLUTION: This ink set is prepared by combining two or more different color inks. Each ink contains a dye and a liquid medium as essential components. At least one color ink contains a high molecular weight material, and the other ink having a different color from that of the preceding ink contains a water soluble dye and an amphoteric compound. An ink jet recording using this ink set is performed. |
