The invention discloses an emulsion film for a peep-proof film and a preparation method and application thereof, the emulsion film comprises a plurality of light-sensitive sub-layers, the plurality of light-sensitive sub-layers respectively sense light in different wavelength ranges, or the plurality of light-sensitive sub-layers all sense light in the same wavelength range, and the plurality of light-sensitive sub-layers respectively sense light in the same wavelength range. And in the direction from the base material to the protective film layer, the light sensitivities of the plurality of light-sensitive sub-layers are gradually reduced. Therefore, developed silver particles can be effectively prevented from appearing in the blank area, and the transmittance is greatly improved.

The invention provides an industrial X-ray film and a preparation method thereof, and relates to the field of industrial X-ray films. The preparation method of the industrial X-ray film comprises the following steps: preparing a silver halide cubic particle emulsion, carrying out in-situ composite modification, preparing an emulsion layer coating liquid, and carrying out coating molding. According to the preparation method of the industrial X-ray film, the problems of obvious image granularity, transverse migration of silver atoms and combination of development centers between adjacent particles can be effectively solved, the utilization rate of X-ray photons is improved while the image resolution is improved, and the photosensitive sensitivity and the photosensitive response range are effectively improved; and the long-term stability, especially the pressure stability and the environmental stability, of the industrial X-ray film is improved.

An image forming method, an image forming apparatus, and a recording medium are provided. An image forming method forms a viewing image by exposing a photographic photosensitive material using an input image and performing a developing process. The viewing image includes an image (A) of a first image area that is relatively early in a time of image appearance recognition after the developing process starts and an image (B) of a second image area that is relatively late. First, two original images are acquired, and a first original image and a second original image corresponding to the first image area and the second image area, respectively, are determined. A first drawing condition that satisfies a condition of the time of image appearance recognition of the first image area and a second drawing condition that satisfies a condition of the time of image appearance recognition of the second image area are made for the first original image and the second original image, respectively. An input image for forming the viewing image is generated from the first original image and the first drawing condition and the second original image and the second drawing condition.
