Abstract
In the dye transfer printing processes, 10wering sublimation temperatures of transfer dyes improves the sensitivities of dye transfer ink, but decreases the stabilities of recording images. To keep both the high sensitivities and the good stabilities, it is generally said that introduction of the electron-acceptable materials to recording media is effective, because the dye and the medium resin form a complex.
We investigated the relation between the stabilities of the images and the equilibrium constants of complex formation of dye and several kinds of medium resins. It is revealed that the stability of images increases with the increase of equilibrium constants. The complex formation is effective not only in suppressing resublimation of dyes from resin medium but also in preventing the diffusion of dyes in the medium.
