One embodiment of the present invention provides an ink set and an application thereof. The ink set includes at least an ink containing a compound represented by the general formula (Y-1) or (Y-2), etc., and an ink containing a compound represented by the general formula (M) The compound shown or the ink of the following general formula (MM), etc., the ink containing the compound represented by the general formula (C), etc., and the ink containing the compound represented by the general formula (B), etc., each ink composition is relative to each The total mass of the ink composition contains 0.5-5.0% of N-containing solvent A with SP value of 22-26MPa 1/2 , 0.1-5.0% of N-containing solvent B with SP value of 24-29MPa 1/2 , 10 ～50% of N-free solvent C with SP value of 29-31MPa 1/2 , 5-30% of N-free solvent D with SP value of 32-34MPa 1/2 , and 30-60% of water. The ratio of the total mass of Li contained in the entire ink in which the ink composition is mixed at an equal mass ratio relative to the total mass of the alkali metals is 70% or more. |
