<p>PROBLEM TO BE SOLVED: To obtain color ink set for ink jet recording, excellent in reproducibility of color without depending on a material to be recorded, not causing clogging to ultrafine nozzle head and having following property to further sufficient printing frequency and provide a method for carrying out ink jet recording by using the ink set. SOLUTION: This color ink set for ink jet recording has Magenta ink, cyan ink and yellow ink. Each ink comprises at least water, a coloring material and a water-soluble organic solvent. In the ink, an absorption coefficient A in wavelengthλA (nm) in which visible absorption spectrum of ink at pH 4-5 exhibits maximum absorption and an absorption coefficient B in wavelengthλB (nm) in which visible absorption spectrum of ink at pH 7-9 satisfy (a) the formula 0.85<=A/B<=1.20 and (b) -10<=(λB-λA) <=10.</p> |
