摘要:
An ink-jet recording liquid using a dye and a pigment, which is excellent in dispersibility and has good printing performance and storage stability, and a process for producing the same are provided.There are provided an ink-jet recording liquid containing a pigment, a dye and a surfactant which are incorporated in an aqueous medium, characterized in that (1) the pigment and the dye at least partly comprise a pigment and a dye reversibly adsorbed thereon without involving a chemical reaction, (2) the dye reversibly adsorbed on the pigment without involving a chemical reaction contains a dye having a dye adsorption shown by the following formula (1) of 0.02 g/g or more, and (3) as the surfactant, a nonionic surfactant and an anionic surfactant coexist; and a process for producing the same.
