PURPOSE:To raise discoloration-preventing effect and to retain this effect constantly for a long time, by adding a specified phenol derived a discoloration-preventing agent to a mordanting layer containing a diffusion transferred dye image and a white reflective layer serving as the background of thie dye image. CONSTITUTION:A color diffusion transfer photographic print is provided with a white reflective layer serving as the background of a mordanting layer on a support. This reflective layer contains a white pigment, such as rutile type titanium oxide and a compound represented by the formula in white R is alkyl, aryl, aralkyl; R1- R4 are each H, halogen, alkyl, aryl, alkenyl, aralkyl, alkoxy, aryloxy, alkylthio, acyl, alkylamino, acylamino, alkoxycarbonyl, acyloxy, orothe like, but when R is alkyl and R1-R4 are each H or alkyl, the total C number of R, R1-R4 is >=6. This print has high discoloration prevention effect, and long-term retentivity of this effect, and remarkably improved light fastness of a dye image, and it prevents the white background from staining. |
