A heat developable light-sensitive material is disclosed. The material comprises a support having provided thereon at least a light-sensitive silver halide, a reducing agent, a binder and an organic silver salt of the formula:
wherein R, represents a hydrogen atom or a substituted or unsubstituted alkyl, cycloalkyl, alkenyl, alkynyl, aralkyl, aryl or heterocyclic group; R2 represents a hydrogen atom or a substituted or unsubstituted alkyl group; R, represents a halogen atom, a substituted or unsubstituted alkyl, alkoxy, amino, alkylsulfonyl, arylsulfonyl, carbamoyl, sulfamoyl or alkoxycarbonyl group or a cyano group; X represents
, wherein R4 represents a hydrogen atom or a substituted or unsubstituted alkyl group,
, wherein R5 represents a substituted or unsubstituted alkyl group, and
: and t represents 0 or an integer of from 1 to 3; and when ℓ is 2 or 3, the groups R3 may be the same or different. The material provides an image of high density with less fog in a short time even using a reduced amount of a base precursor.
本发明公开了一种热显影光敏材料。该材料包括一种支撑物,支撑物上至少有一种光敏卤化银、一种还原剂、一种粘合剂和一种式中的有机银盐:
其中 R 代表氢原子或取代或未取代的烷基、环烷基、烯基、炔基、芳烷基、芳基或杂环基团; R2 代表氢原子或取代或未取代的烷基; R 代表卤素原子、取代或未取代的烷基、烷氧基、氨基、烷基磺酰基、芳基磺酰基、氨基甲酰基、氨基磺酰基或烷氧羰基或氰基; X 代表
其中 R4 代表氢原子或取代或未取代的烷基、
其中 R5 代表取代或未取代的烷基,和
当 ℓ 为 2 或 3 时,基团 R3 可以相同或不同。即使使用较少量的碱前体,该材料也能在短时间内提供高密度、雾少的图像。
