Reduction of reticulation in gelatin-containing elements |
摘要 |
Reticulation caused by swelling with processing solutions in photographic elements is reduced for elements containing at least two contiguous gelatin-containing layers wherein the uppermost layer has a lateral swell coefficient at least 10% greater than the lower gelatin-containing layer before polymer addition and wherein said uppermost layer comprises an essentially non-diffusible vinyl polymer having reactive groups which crosslink by reaction with primary amine or secondary amine groups on gelatin or a water-soluble, non-diffusible amine containing vinyl polymer and a hardener for gelatin. These elements are particularly useful in photographic products.
