(57) [Abstract] [Problem] To be excellent in ejection stability and storage stability, and to achieve color tone, An organic pigment capable of providing an image having good image fastness such as water fastness and light fastness, a method for producing the same, a recording liquid containing the organic pigment, a recording liquid cartridge containing the recording liquid, and the recording liquid cartridge. Provided is a recording apparatus provided with the recording liquid and a recording method using the cartridge. SOLUTION: A crude pigment having an amino group on its surface is reacted with an acylating agent such as an acid anhydride, and a hydrophilic group is bonded to the amino group via a linking group. |
