PURPOSE:To improve the ability of thickening the dot of the titled material, and of preventing generation of a pine hole by incorporating a compd. which is converted to a color matter capable of sensitizing a silver halide particle by exposing, and a hydrazine compd. in the titled material. CONSTITUTION:The compd. which is converted to the color matter capable of sensitizing the silver halide particle by exposing, and the hydrazine compd. are incorporated in the silver halide sensitive material having mainly the photosensitivity of 300-450nm. Namely, said compd. is composed of a compd. capable of converting by exposing an image on the photosensitive material for the light room, and comprises an org. photochromic compd. capable of coloring by a light energy. Thus, the ability of thickening the dot and the pin hole preventing characteristic of the titled material are improved. |
