Abstract (en)
Light-sensitive silver halide photographic material to obtain black-and-white half-tone, dot or line, images comprising a support and coated thereon one or more hydrophilic layers, at least one of said hydrophilic layers including a high chloride content silver halide emulsion, wherein said silver halide emulsion comprises a polyhydroxybenzene and wherein the outermost hydrophilic layer comprises wax-like polyolefine particles having an average size ranging from 0.5 to 3 mu m. The photographic material shows a better resistance to pressure desensitization.
