    • An image forming process comprises the steps of image-wise exposing to light a light-sensitive material, heating the light-sensitive material to develop the silver halide within the exposed area and to harden the hardening layer, and removing the light-sensitive layer and the unhardened area of the hardening layer from the light-sensitive material with an etching solution to form a replica image of the hardened area on the support. The light-sensitive material comprises a support, a hardening layer and a light-sensitive layer in this order. The hardening layer contains an ethylenically unsaturated polymerizable compound represented by the formula (I).A(--NH--CO--Y--L--Q.sub.n).sub.m (I)in which A is an m-valent organic group having 1 to 50 carbon atoms; Y is --O-- or --NR--, wherein R is hydrogen or an alkyl group having 1 to 12 carbon atoms; L is an (n+1)-valent aliphatic group having 1 to 10 carbon atoms; Q is acryloyloxy or methacryloyloxy; n is 1, 2 or 3; and m is 2, 3, 4, 5 or 6.
    • 图像形成方法包括以下步骤:对光敏材料进行成像曝光,加热感光材料以在曝光区域内显影卤化银并硬化硬化层,以及去除感光层和 通过蚀刻溶液使来自感光材料的硬化层的未硬化区域形成载体上的硬化区域的复制图像。 感光材料依次包括支撑体,硬化层和光敏层。 硬化层含有由式(I)表示的烯键式不饱和可聚合化合物。 A(-NH-CO-Y-L-Qn)m(I)其中A是具有1至50个碳原子的m价有机基团; Y是-O-或-NR-,其中R是氢或具有1至12个碳原子的烷基; L为碳数1〜10的(n + 1)价的脂肪族基团, Q是丙烯酰氧基或甲基丙烯酰氧基; n为1,2或3; m为2,3,4,5或6。
