Sublimation dye ink printing method

A printing method, comprising:

• an ink applying step, for applying an ink on a recording medium, and the ink containing:
• binder resin particles in which a sublimation dye is enclosed and a solvent, and the binder resin particles are directly dispersed or emulsified in the solvent;
• and
• a heating step, for heating the ink applied on the recording medium to diffuse the sublimation dye within the binder resin particles for color development,
• the sublimation dye are incorporated and enclosed in a resin matrix when producing the binder resin particles,
• wherein the binder resin particles are formed into a film by bonding a binder resin of the binder resin particles to each other,
• the ink applying step further comprises:
• a film forming step of evaporating the solvent from the ink applied on the recording medium so as to form the film containing the binder resin,
• in the heating step, the film is heated, and the sublimation dye is sublimated and diffused into the film so that the film is color-developed.
