  • Patent number: 5102780
    Abstract: The present invention provides a silver halide photographic photosensitive material excellent in dimensional stability which comprises a polyethylene terephthalate film support and, provided thereon, at least one gelatin layer containing an active halogen type hardener, wherein water content in the gelatin layer is 20% by weight or less based on total amount of gelatin. Further provided is a method for producing such silver halide photographic photosensitive material which comprises coating a gelatin coating solution containing an active halogen type hardener on a polyethylene terephthalate film support and then drying the coat, wherein the coat is dried so that water content based on total amount of gelatin is 20% by weight or less and then, is subjected to a heat treatment.
