<p>An ink composition is disclosed which can realize an image possessing excellent rubbing/scratch resistance and color reproduction in color ink jet recording and has advantages as a superpenetrating ink composition. The ink composition comprises at least a specific colorant, water, a water-soluble dispersant, and a penetrant, wherein the penetrant is 0.1 to 5% by weight of an acetylene glycol compound and the water-soluble dispersant is a water-soluble styrene/(meth)acrylic acid resin in an amount of 0.1 to 1 part by weight on a solid basis based on the pigment. An ink set capable of forming an excellent color image in color ink jet recording is also disclosed which comprises an orange ink composition and/or a green ink composition in combination with a yellow ink composition, a magenta ink composition, and a cyan ink composition that have hitherto been used in the color ink jet recording. The ink set consists essentially of three ink compositions, a yellow ink composition, a magenta ink composition, and a cyan ink composition, and, in addition, an orange ink composition and/or a green ink composition.</p> |
