ABSTRACT:
Polymeric mordants which are capable of converting to non-mordanting species in an alkaline environment are described. The mordants can be used in photographic elements to temporarily mordant a photographically useful dye material, such as a light-filter or anti-halation dye or a diffusion transfer image dye-providing material, and then release the dye material during processing of the element with an alkaline processing composition.
