Abstract
Color reversal photographic elements can be effectively processed to provide color positive images using biodegradable bleaching compositions when the following fixing compositions contain an uncomplexed aminodisuccinic acid additive. The presence of the additive in the fixing composition seems to reduce the retained iron from use of the biodegradable bleaching composition, thereby reducing yellow stain and other undesirable effects in the color images, and iron precipitates in the fixing bath.
