PURPOSE:To provide a dye transfer material capable of holding saturated recording density over a large number of times by laminating a dye high concn. layer containing a dye and a binder rosin and a dye permeable low concn. layer to a substrate and crosslinking the binder resin by a crosslinking agent. CONSTITUTION:A dye high concn. layer 9 containing at least a dye and a binder resin and a dye permeable low concn. layer 10 having dye concn. lower than that of the high concn. layer and containing at least a water-soluble or water- dispersible resin are successively laminated to a base material 2. As the binder resin of the dye high concn. layer 9, a thermoplastic resin capable of well diffusing the dye and having low thermal deformation temp. is used and the binder resin is crosslinked and cured by a crosslinking agent to increase the mechanical strength of the dye high concn. layer 9. As the binder resin crosslinked and cured by said crosslinking agent, polyisocyanates are used and, as the water-soluble resin, a graft or block copolymer of polydimethylsiloxane containing a polydimethylsiloxane structure is used. |
