    • A heat developable light-sensitive material comprises a support, a light-sensitive layer and a non-light-sensitive layer. The light-sensitive layer contains silver halide and a reducing agent. The non-light-sensitive layer contains a cyanine dye represented by the formula (I) or a salt thereof and a base precursor: in which R1 is hydrogen, an aliphatic group, an aromatic group, —NR21R24, —OR21 or —SR21, each of R21 and R24 independently is hydrogen, an aliphatic group or an aromatic group, or R21 and R24 are combined to form a nitrogen-containing heterocyclic ring; R2 is hydrogen, an aliphatic group or an aromatic group; R3 is an aliphatic group; L1 is a methine chain consisting of an odd number of methines; and each of Z1 and Z2 independently is an atomic group forming a five-membered or six-membered nitrogen-containing heterocyclic ring. A heat development image forming process, a thermal image recording material, a thermally decoloring image recording process and a process for decoloring a cyanine dye are also disclosed.
    • 可热显影的感光材料包括支撑体,感光层和非感光层。 感光层含有卤化银和还原剂。 非光敏层含有由式(I)表示的花青染料或其盐和碱前体:其中R 1是氢,脂族基,芳基,-NR 21 R 24,-OR 21或-SR 21, R 21和R 24各自独立地为氢,脂族基团或芳族基团,或R 21和R 24结合形成含氮杂环; R2是氢,脂族基或芳基; R3是脂族基团; L1是由奇数个次甲基组成的次甲基链; Z1和Z2各自独立地为形成五元或六元含氮杂环的原子团。 还公开了热显影图像形成方法,热图像记录材料,热脱色图像记录方法和花青染料脱色方法。
