<P>PROBLEM TO BE SOLVED: To provide an inkjet ink set capable of forming a recorded image of high quality, scarcely causing change in color balance as well even when the formed image is stored in an oxidizing atmosphere, and capable of maintaining the quality of the image, and to provide an inkjet recording method. <P>SOLUTION: This inkjet recording ink set is formed by selecting at least three kinds of inkjet ink of which the each is obtained by dissolving or dispersing a colorant in a water-based or oil-based medium and has a maximum absorption spectrum in a spectroscopic absorption region different from the others, wherein any two of the inkjet ink have such forced discoloration rate constants that a ratio of the rate constant of the one to that of the other is in a range of 0.5 to 2.0, when each of the at least three kinds of the ink printed on a reflection-type image reception medium by using the ink set is measured to obtain the forced discoloration rate constant against ozone gas. <P>COPYRIGHT: (C)2004,JPO |
