A heat-developable photosensitive material comprising a photosensitive layer formed on a support, the photosensitive layer at least containing an organic silver salt, a reducing agent, a photosensitive silver halide or a photosensitive silver halide forming agent, and a sensitizing dye of the following general formula (I):
where r is hydrogen, halogen, substituted or unsubstituted alkyl, substituted or unsubstituted alkoxyl, substituted or unsubstituted aryl or substituted or unsubstituted amino, r¹ and r² are each substituted or unsubstituted aryl or r¹ and r² are bonded to each other to form a condensed ring, r³, r⁴ and r⁵ are each halogen, substituted or unsubstituted alkyl, alkenyl, substituted or unsubstituted aryl, or substituted or unsubstituted aralkyl, X¹ is oxygen, sulfur, carbon, nitrogen or selenium, wherein when X¹ is carbon or nitrogen, then X¹ is boned to hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted aryl, or substituted or unsubstituted aralkyl, X² is oxygen, sulfur or nitrogen, wherein when X² is nitrogen, then X² is bonded to hydrogen, substituted or unsubstituted aryl or substituted or unsubstituted aralkyl, X³ is oxygen or sulfur, and n is 1 or 2. A polymerizable polymer precursor and a light polymerization initiator may also be employed in the material.
一种可热显影的感光材料,包括形成在支持物上的感光层,该感光层至少含有有机银盐、还原剂、感光卤化银或感光卤化银形成剂,以及以下通式(I)的感光染料:
其中 r 是氢、卤素、取代或未取代的烷基、取代或未取代的烷氧基、取代或未取代的芳基或取代或未取代的氨基,r¹ 和 r² 分别是取代或未取代的芳基或 r¹ 和 r² 相互键合形成缩合环,r³、r⁴ 和 r⁵ 分别是卤素、取代或未取代的烷基、烯基、取代或未取代的芳基或取代或未取代的芳烷基、X¹是氧、硫、碳、氮或硒,其中当 X¹ 是碳或氮时,则 X¹ 与氢、取代或未取代的烷基、取代或未取代的芳基或取代或未取代的芳烷基键合,X²是氧、硫或氮,其中当 X² 是氮时,则 X² 与氢、取代或未取代的芳基或取代或未取代的芳烷基键合,X³是氧或硫,且 n 是 1 或 2。材料中还可使用可聚合聚合物前体和光聚合引发剂。
