Abstract (en)

[origin: EP0264954A2] A silver halide photographic material having excellent color sensitizability, which comprises a support having thereon at least one light-sensitive silver halide emulsion layer comprisingchemically sensitized silver halide grain having a silver halide core portion comprising about 10 to 40 mol % silver iodide, substantially surrounded by a silver halide shell portion containing less silver iodide than the core portion and the silver halide of the surface region of the shell portion contains at least about 5 mol % silver iodide.
