Ink set, ink jet recording method, recording unit, ink cartridge and ink jet recording apparatus

摘要

An ink set includes inks each containing a colorant and an aqueous medium, wherein in a fading test under conditions that cause fading corresponding to pseudo-indoor sunlight fading through a window for 3 years or more, the difference between respective images' DELTAE, the images being produced with the respective inks, is 10 or less in a CIELAB color space display system, and each of the images has a residual ratio of reflection density of 70% or more. By using the ink set including the color inks with which images having substantially the same fading DELTAE after long-term storage are produced, the color balance of a recorded image can be maintained after long-term storage.
