Light-sensitive silver halide photographic elements are disclosed comprising a support and silver halide emulsion layer or layers, wherein at least one of said silver halide emulsion layers contains tabular silver halide grains having an average diameter:thickness ratio of at least 3:1 and highly deionized gelatin and wherein said photographic elements show a swelling index lower than 140% and a melting time of from 45 to 120 minutes. The light-sensitive materials can be advantageously developed in hardener free developer and used in high temperature super rapid processing in automatic processors which include transporting rollers and have good physical and photographic characteristics.

Light-sensitive silver halide photographic element

A silver halide emulsion for use in a radiographic element,--comprising at least one silver halide emulsion layer coated on one side or on both sides of a transparent support--, characterized by the fact that it contains silver halide cubic grains having J-band spectral sensitizing dyes adsorbed on the surface thereof in a quantity substantially higher than that amount which substantially optimally sensitizes said grains, exhibits a reduced residual stain and an improved image quality.
