The present invention relates to a developer mixture for a thermal recording material, which comprises a mixture of the first organic developer comprising a condensate or a condensed composition represented by the formula (I):
wherein R is a lower alkyl group or an aralkyl group, n is an integer of 0 to 5, and X and Y are each a hydrogen atom, an alkyl group or an aryl group, and
the second organic developer other than the first organic developer (except 2,2-bis(3-methyl-4-hydroxyphenyl)propane), a developer mixture for a thermal recording material, and a thermal recording material having a heat-coloring layer containing the developer mixture. Using the developer mixture for a thermal recording material of the present invention, a thermal recording material sufficiently satisfying the recent requirement for high sensitivity, and having superior preservation stability of color images and non-image areas can be realized.
本发明涉及一种用于热记录材料的显影剂混合物,其包括第一有机显影剂的混合物,所述第一有机显影剂包括由式(I)表示的缩聚物或缩合物,其中R是低级烷基或芳基烷基,n为0至5的整数,X和Y分别是氢原子、烷基或芳基,以及除第一有机显影剂(2,2-双(3-甲基-4-羟基苯基)丙烷)以外的第二有机显影剂,一种用于热记录材料的显影剂混合物,以及具有含有显影剂混合物的热成像层的热记录材料。使用本发明的热记录材料的显影剂混合物,可以实现满足高灵敏度的最近需求,并具有色彩图像和非图像区域的优异保存稳定性的热记录材料。
