A dye-donor element for thermal dye transfer comprises a support having thereon a dye dispersed in a polymeric binder, characterized in that the dye has the formula:
wherein R¹ and R² each independently represents a substituted or unsubstituted alkyl group having from 1 to 10 carbon atoms, a cycloalkyl group having from 5 to 7 carbon atoms or an aryl group having from 6 to 10 carbon atoms;
R³ and R⁴ each represents R¹; or either or both of R³ and R⁴ can be joined to the carbon atom of the aromatic ring at a position ortho to the position of attachment of the anilino nitrogen to form a 5- or 6-membered ring; or R³ and R⁴ can be joined together to form, along with the nitrogen to which they are attached, a 5- or 6-membered heterocyclic ring;
R⁵ represents hydrogen; halogen; cyano; carbamoyl; alkoxycarbonyl; acyl; a substituted or unsubstituted alkyl or alkoxy group group having from 1 to 10 carbon atoms; a cycloalkyl group having from 5 to 7 carbon atoms; an aryl group having from 6 to 10 carbon atoms; or a dialkylamino group; and
Z represents hydrogen or the atoms necessary to complete a 5- or 6-membered ring.
一种用于热染料转移的染料供体元件包括一个支座,其上有分散在聚合物粘合剂中的染料,其特征在于染料具有以下式子:
其中 R¹ 和 R² 各自独立地代表具有 1 至 10 个碳原子的取代或未取代的烷基、具有 5 至 7 个碳原子的环烷基或具有 6 至 10 个碳原子的芳基;
R³ 和 R⁴ 各自代表 R¹;或 R³ 和 R⁴ 中的一个或两个可在苯胺基氮连接位置的正交位置与芳香环的碳原子连接,形成 5 或 6 元环;或 R³ 和 R⁴ 可连接在一起,与所连接的氮一起形成 5 或 6 元杂环;
R⁵ 代表氢;卤素;氰基;氨基甲酰基;烷氧基羰基;酰基;具有 1 至 10 个碳原子的取代或未取代的烷基或烷氧基基团;具有 5 至 7 个碳原子的环烷基;具有 6 至 10 个碳原子的芳基;或二烷基氨基;和
Z 代表氢或完成 5 或 6 元环所需的原子。
