摘要: Photographic elements are disclosed which contain a blocked development restrainer which is designed to provide timely release of a development restrainer when the photographic element is processed with an alkaline processing composition. The photographic elements are especially useful in image-transfer film units where the blocked development restrainers will permit initial development to occur and, upon cleavage, will substantially restrain further development.
