    • A light-sensitive material comprising a light-sensitive layer which contains silver halide, a reducing agent and a polymerizable compound provided on a support, characterized in that the reducing agent is a hydrazine derivative having the following formula (I): ##STR1## in which R.sup.1 is a monovalent group selected from the group consisting of hydrogen, an alkyl group, a cycloalkyl group, an alkenyl group, an aryl group, an aralkyl group, an alkynyl group and a heterocyclic group, each of which may have one or more substituent groups; each of R.sup.2 and R.sup.3 independently is an aryl group which may have one or more substituent group, or R.sup.2 and R.sup.3 form, together with the neighboring carbon, a condensed aromatic ring; R.sup.4 is a monovalent group selected from the group consisting of an aryl group, a heterocyclic group, hydrogen, an alkyl group, an alkoxycarbonyl group and carbamoyl, each of which may have one or more substituent groups. Image-forming method utilizing the light-sensitive material is also disclosed.
    • 一种感光材料,其包含含有卤化银,还原剂和提供在载体上的可聚合化合物的感光层,其特征在于还原剂是具有下式(I)的肼衍生物: I),其中R 1是选自氢,烷基,环烷基,烯基,芳基,芳烷基,炔基和杂环基的一价基团,其各自可以具有 一个或多个取代基; R 2和R 3各自独立地是可以具有一个或多个取代基的芳基,或者R 2和R 3与邻近的碳一起形成稠合芳香环; R4是选自芳基,杂环基,氢,烷基,烷氧基羰基和氨基甲酰基的一价基团,其各自可以具有一个或多个取代基。 还公开了利用感光材料的成像方法。
