Abstract
Abstract A color diffusion transfer photographic element is disclosed. The element provides a transferred dye image in a mordant layer and includes a compound having recurrent units represented by the general formula (I): ##STR1## the substituents within the general formula (I) are defined within the specification. By utilizing the compound the images produced having improved preservability having specific improvements with respect to the elimination of yellow stains which are formed in white areas of the images after storage for a long period of time. Furthermore, the images formed do not deteriorate at high temperatures and the use of the compound does not decrease the D max in print images.
