Ink jet recording ink, ink jet image-forming method and ink jet recording apparatus |
摘要 |
The invention provides an ink jet recording ink containing a self-dispersion pigment having a lactone group and a carboxyl group, an organic carboxylic acid salt, water and a water-soluble substance having a coefficient of hydrophilicity-hydrophobicity of 0.37 or more as defined by the following equation (A), and having a surface tension of 34 mN/m or less. Coefficient of hydrophilicity-hydrophobicity=[(Water activity value of a 20% aqueous solution)−(Molar fraction of water in the 20% aqueous solution)]/ [1−(Molar fraction of water in the 20% aqueous solution)]  Equation (A) |
