A process for developing a light-sensitive material comprising a support having thereon at least one internal latent image-forming silver halide photographic emulsion layer which comprises, after imagewise exposure, developing the light-sensitive material with an alkaline solution of a developing agent in the presence of a compound represented by the formula I which is capable of selectively forming latent images in the inner portions of said silver halide upon development: ##STR1## wherein Y represents an acyl group or a cyano group and said acyl group and the 3-, 4- or 5-position of the pyridinium ring may be optionally substituted.
一种制备光敏材料的方法,包括在支撑体上至少有一层内部潜影形成的银卤化物感光乳剂层,该层在图像曝光后,通过在存在式I所表示的化合物的碱性溶液存在下,使用一种显影剂选择性地在银卤化物的内部形成潜影像:##STR1## 其中,Y代表酰基或氰基,且所述酰基和吡啶环的3-、4-或5-位置可选择性地被取代。
