| abstract |
The present invention provides excellent image uniformity between various recording media regardless of the recording medium, and can suppress occurrence of ink bleeding, non-uniform line width, color unevenness, etc. The present invention also provides an undercoat liquid, an ink jet recording method, and an ink jet recording apparatus capable of maintaining a uniform dot diameter and recording with high density and high reproducibility over details regardless of the image form. An undercoating liquid for preliminarily applying an ink onto a recording medium by discharging ink onto the recording medium, wherein the polymer and a phosphate polymer have a radical polymerization property. And an undercoating liquid comprising the compound. [Selection figure] None |
