<p>Photographic assemblages, elements, receiving elements and cover sheets are described employing a neutralizing layer comprising about 75 to about 150 meq. of acid/m2 of element for neutralizing an alkaline processing composition. The neutralizing layer, timing layer or layer adjacent thereto also contains about 1 to about 10 meq./m2 of oxalic acid, or an acid salt thereof, to minimize sensitometric changes that occur with keeping.</p> |
