    摘要： A dye transfer sheet consisting of a transfer substrate and a coloring material layer comprising a high concentration layer which comprises a dye and is formed on the transfer substrate and a low concentration layer which comprises a water soluble resin or water dispersible resin having a polydimethylsiloxane structure and has a lower dye concentration than the high concentration layer and is formed on the high concentration layer. A dye transfer sheet consisting of a transfer substrate and a coloring material layer comprising a high concentration layer which comprises a dye and a binder polymer cross-linked with a cross-linking agent and is formed on the transfer substrate and a low concentration layer which comprises a water soluble resin or water dispersible resin and has a lower dye concentration than the high concentration layer and is formed on the high concentration layer. The dye transfer sheet of the present invention can be used in a multiple-use mode printing system including a relative speed printing.

    摘要： Thermal dye transfer printing systems which are adapted For multiple-use printing modes wherein one dye transfer sheet is repeatedly used and which comprise a dye transfer sheet having, on a substrate, a dye transfer layer containing a sublimable dye and a binder resin and a dye receiving sheet having a dye receiving layer which has a diffusion rate of the dye smaller than the dye transfer layer. This is effective in suppressing a lowering of printing density owing to the increase in number of printing cycles using one dye transfer sheet. Alternatively, the dye transfer sheet is constituted such that the dye transfer layer is made of a plurality of sub-layers in which the concentration of the dye decreases from the sub-layer formed directly on the substrate toward the surface side of the dye transfer layer. The dye is invariably supplied from the higher concentration sub-layers to ensure full color printing with a remarkably increasing number of multiple-use printing cycles.

    摘要翻译： 适合于多次使用印刷模式的热染料转印印刷系统，其中重复使用一种染料转印片，并且其包含在基材上具有含有可升华染料和粘合剂树脂的染料转移层和染料的染料转移片 具有染料接收层的接收片材，其染料的扩散速率小于染料转移层。 由于使用一个染料转印片的印刷循环次数的增加，这抑制了印刷浓度的降低是有效的。 或者，染料转印片构成为使得染料转移层由多个子层制成，其中染料浓度从直接在基底上形成的子层朝向染料转移层的表面侧减少 。 染料总是从较高浓度的子层提供，以确保全彩色印刷，显着增加数量的多用途印刷循环。
