摘要:
An ink for ink jet recording that has excellent color development, has a high level of environmental gas resistance, and, further, can yield images having excellent bronze resistance. The ink comprises at least a colorant. The colorant is a compound represented by general formula (I) or its salt. The content (% by mass) of the colorant is not less than 3.0% by mass based on the total mass of the ink for ink jet recording. The dispersion distance d75 value, occupying 75% of a dispersion distance distribution of molecular aggregates in an ink prepared in such a manner that the concentration of the colorant in the ink forink jet recording is 3.0% by mass, as determined by a small angle X-ray scattering method is not less than 6.50 nm to not more than 7.10 nm.
