ABSTRACT:
Disclosed is a color diffusion transfer photographic element having a neutralization system for lowering the pH value of an alkaline processing solution, wherein the said neutralization system contains a reducing sugar in an amount of from 0.1 to 20 mmol/m.sup.2. The element may be a monosheet type element comprising a light-sensitive element and a cover sheet, and the neutralization system may be present either in the light-sensitive element or in the cover sheet. By the addition of the reducing sugar to the neutralization system, the image storability (light-fastness) under high temperature and high humidity conditions can be improved.
