Abstract
A recording liquid is provided. The recording liquid includes particles A including a water-insoluble colorant and a compound containing a hydrophilic group, the particles A having a dispersion average particle diameter from 5 to 50 nm; and a self-dispersible polymer particles B including a constituent unit derived from an aromatic group-containing acrylate monomer.

A recording liquid comprising:
- particles A including a water-insoluble colorant and a compound containing a hydrophilic group, the particles A having a dispersion average particle diameter from 5 to 50 nm and the compound containing a hydrophilic group being a polymer dispersant;
- and
- self-dispersible polymer particles B including a constituent unit derived from an aromatic group-containing acrylate monomer, wherein the compound containing a hydrophilic group has an acid value, and the self-dispersible polymer particles B have an acid value, and
- wherein the acid value of the self-dispersible polymer particles B is smaller than the acid value of the compound containing a hydrophilic group.
