PURPOSE:To obtain the titled material capable of easily obtaining a female mask by incorporating a negative type photosensitive silver halide to a blue color sensitive emulsion layer, and by incorporating an autopositive type photosensitive silver halide emulsion to green and red color sensitive emulsion layers respectively. CONSTITUTION:The red color sensitive emulsion layer RL, the green color sensitive emulsion layer GL and the blue color sensitive emulsion layer BL are coated on a transparent substrate in order from said substrate. The negative type photosensitive silver halide emulsion is incorporated in the blue color sensitive emulsion layer, and the autopositive type photosensitive silver halide emulsion is incorporated into the red and green color sensitive emulsion layers respectively. The original blue color is a yellow color in the negative film, and the photosensitive material is exposed with a white light through the negative film, thereby exposing the green and red color sensitive emulsion layers, and making it impossible to develop. And the blue color sensitive emulsion layer does not expose, and makes it impossible to develop. As the result of the developing treatment, the original blue color part becomes a white (a transparent). While, any one of the original red, yellow, magenta, cyan, black and white color parts is surely blackened, thereby obtaining the female mask image. |
