Abstract An ink is provided which is capable of forming a recorded image with improved water resistance and improved ozone resistance of recorded images which are not achievable by conventional aqueous inks employing a water-soluble dye as the coloring agent, and also capable of forming images having improved fixability, improved color developability, and improved ozone resistance which are not achievable by conventional dispersion type inks employing a pigment as the coloring agent. The ink is useful widely for recording like ink-jet recording, and gives recorded images having high rub resistance and high ozone resistance and being excellent in color development and image transparency. The aqueous ink comprises a colored resin dispersed therein, and the colored resin is composed of a film-forming resin and a colorant dispersed in a monomolecular state in the film-forming resin.

An ink-jet recording method comprising a step of ejecting an aqueous ink through an orifice in correspondence with a recording signal to deposit the ejected ink onto a recording medium, wherein: the ink comprises glycerol or ethylene glycol, and a colored resin particle dispersed in an aqueous medium, the colored resin particle comprises an acrylic film-forming resin to which at least one of an oil soluble dye and a disperse dye is sublimed and penetrated, and the film-forming resin has a minimum film-forming temperature (MFT) of not higher than 35° C.
