Abstract
A method is described to provide a radiographic silver halide material by coating on at least one side of a support, covered with a hydrophobic subbing layer comprising as a latex copolymer vinylidene chloride, methylacrylate and itaconic acid, following hydrophilic layers: at least one gelatinous dye containing layer comprising one or more dyes, at least one silver halide emulsion layer, at least one protective antistress layer, and optionally an afterlayer, characterized in that said hydrophilic layers have a swelling ratio of not more than 200% and in that said hydrophilic layers are coated simultaneously by the slide-hopper coating or by the slide-hopper curtain coating technique.

Method to provide a radiographic silver halide material by coating in consecutive order on at least one side of a support, covered with a hydrophobic subbing layer comprising as a latex copolymer vinylidene chloride, methylacrylate and itaconic acid following hydrophilic layers:
- at least one gelatinous dye containing layer comprising one or more dyes wherein the said dye(s) is(are) present in a total amount of not more than 300 mg/m.sup.2 in an amount of hydrophilic binder such that the ratio by weight of dye to gelatin is between 0.4 and 1.3,
- at least one silver halide emulsion layer,
- at least one protective antistress layer, characterized in that said hydrophilic layers have a swelling ratio of not more than 200% and in that said hydrophilic layers are coated simultaneously by the slide-hopper coating or by the slide-hopper curtain coating technique.
