Gelatin-containing elements.

摘要

Reticulation caused by swelling with aqueous solutions 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 by adding to the uppermost layer 1 - 90 % by weight of a water-soluble, non-diffusible vinyl polymer having (a) reactive groups which crosslink the polymer and gelatin, or (b) amine groups, the uppermost layer also containing a gelatin hardener when the polymer contains no cross-linking groups. These elements are particularly useful in photographic products.
