A process for forming an image which comprises heating a light-sensitive material comprising a support having thereon at least a light-sensitive silver halide, a binder and a dye-releasing redox compound which is reductive to the light-sensitive silver halide and which is capable of releasing a hydrophilic dye upon reaction with the light-sensitive silver halide on heating, after imagewise exposure or simultaneously with imagewise exposure, in a substantially water-free condition the dye-releasing redox compound being represented by the formula (I) wherein R represents a phenyl group having a hydroxy-substituted alkoxy group or an alkoxy-substituted alkoxy group at at least the 2-position thereof with respect to the diazo group and a group of the formula --SO.sub.2 NH--Y at the 5-position thereof with respect to the diazo group where Y represents a group capable of being oxidized silver halide to release a dye moiety including the --SO.sub.2 NH moiety.
一种制备图像的方法,包括加热一种光敏感材料,该材料包括具有至少一种光敏感银卤化物、粘合剂和释放染料的氧化还原化合物的支撑物,在影像曝光后或与影像曝光同时,在基本无水的条件下加热,释放染料的氧化还原化合物由式(I)表示,其中R表示苯基,其在2-位和/或更高位上具有羟基取代的烷氧基或烷氧基取代的烷氧基,并且在5-位上具有式--SO.sub.2 NH--Y的基团,其中Y表示一种能够将银卤化物氧化以释放染料基团,包括--SO.sub.2 NH基团。
