PURPOSE:To improve blocking resistance and antistaticness by using particles containing a fluorinated polymer having alkali-soluble groups for a matting agent. CONSTITUTION:The photographic sensitive material is roughened with the matting agent on at leas one surface, and the matting agent is composed of the particles containing the fluorinated polymer having alkali-soluble groups. the matting agent has, preferably, an average particles diameter of 0.1-10mum, and when they are mixed with the binder of the outermost layer, said diameter is, preferably, larger than the dry film thickness, and from the viewpoint of the antistaticizing effect, preferably 2, times, especially, 2.5 times as large as that. The more coating amount of the matting agent, the higher effect can be obtained, and it is preferred to add it in an amount of >=10mg/m<2>, and <=500mg/m<2> from the viewpoint of the effect on transparency, the image sharpness and the like. |
