摘要： 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.

摘要： A photographic material has been coated on at least one side of a support with in at least one photosensitive layer hexagonal and/or circular tabular silver halide emulsion crystals occupying at least 70% of the total projected area of all grains, having a thickness of 0.15 to 0.30 .mu.m, a coefficient of variation of the tabular grains between 0.15 and 0.45 and an average aspect ratio of at least 2:1, prepared in the absence of ammonia by growing the nuclei, prepared at a pBr value between 1.0 and 2.0 and consuming less than 10% by weight of silver nitrate, during a first growth step at a pBr value between 1.0 and 2.5 consuming at least 10% by weight of silver nitrate and during a second growth step at a pBr value higher than 2.7 during the addition of at least 40% of the total amount of silver nitrate used. The loss in sensitivity and gradation after development of said material in a diluted cheap developer after exposing said photographic material containing said emulsion grains is neglectable in comparison with the characteristics obtained after development in stronger high quality developers.
