  • Reversal color photographic material
    Patent number: 5378591
    Abstract: The present invention relates to a reversal color photographic material.The material contains three elements which are photosensitive to the three regions of the spectrum respectively. Each element contains at least two emulsions having different speeds. In at least one of the elements, the fastest emulsion is a polydisperse emulsion exhibiting a sensitization higher than the optimum, the other emulsions being monodisperse emulsions.Obtention of a material less sensitive to the processing conditions, without degradation of the other photographic properties.
