Abstract of the Disclosure Photographic elements, diffusion transfer assemblages and processes are described wherein a dye image-receiving layer comprising a poly(vinylimida- zole) mordant is employed in a nonmordanting, water- permeable polymeric vehicle. The polymeric vehicle comprises recurring units derived from a hydroxyalkyl acrylate ester, and/or an N-hydroxyalkylacrylamide, and/or an N-alkylacrylamide. Image sharpness is thereby improved, especially under conditions of high temperature and humidity.
