A light-sensitive material is described, comprising a support having provided thereon a light-sensitive layer containing at least a light-sensitive silver halide, a developing agent, a polymerizable compound, a color image forming substance, and a hydrazine derivative represented by at least one of the following formula (I) and a hydrazine derivative represented by the following formula (II), in which said color image forming substance is immobilized by imagewise exposure to light, followed by heat development under conditions substantially not containing water: ##STR1## wherein R.sub.1 represents a substituted or unsubstituted alkyl, aralkyl, aryl, alkenyl, alkynyl, or heterocyclic group; and R.sub.2 represents a hydrogen atom or a substituted or unsubstituted alkyl, cycloalkyl, aralkyl, aryl, alkenyl, alkynyl, heterocyclic, alkoxy, aryloxy, alkylthio, arylthio, or amino group; ##STR2## wherein R.sub.3 represents a monovalent group derived from a substituted or unsubstituted aromatic ring or aromatic heterocyclic ring; R.sub.4 and R.sub.5 each represents a substituted or unsubstituted aryl group; and R.sub.6 represents a hydrogen atom or a substituted or unsubstituted alkyl, aryl, alkoxycarbonyl or carbamoyl group. The material exhibits high sensitivity and provides a color image through a simple, easy, and rapid dry processing step, with reduced exposure time.
描述了一种光敏材料,包括支撑物,在其上提供了一层光敏层,该光敏层含有至少一种光敏银卤化物、一种显影剂、一种可聚合化合物、一种色像形成物质和由以下公式(I)中至少一种和以下公式(II)中的一种所表示的肼衍生物,其中所述的色像形成物质通过光图像曝光后,在几乎不含水的条件下进行热显影后被固定:##STR1## 其中R.sub.1表示取代或未取代的烷基、芳基烷基、芳基、烯烃基、炔基、或杂环基;R.sub.2表示氢原子或取代或未取代的烷基、环烷基、芳基烷基、芳基、烯烃基、炔基、杂环基、烷氧基、芳氧基、烷硫基、芳硫基或氨基;##STR2## 其中R.sub.3表示来自取代或未取代的芳香环或芳香杂环的一价基团;R.sub.4和R.sub.5分别表示取代或未取代的芳基基团;R.sub.6表示氢原子或取代或未取代的烷基、芳基、烷氧羰基或氨基基团。该材料具有高灵敏度,并通过简单、易于快速的干燥处理步骤提供彩色图像,同时减少曝光时间。
