摘要:
A suitable mordanting polymer for the image receiving layer in a color photographic material for the dye diffusion transfer process is a water-soluble cationic polymer containing glycidyl groups. Such polymers can be made by quaternizing a basic polyurethane, polyurea or polyurea polyurethane of the formula ##STR1## with a quaternizing agent capable of introducing glycidyl groups. The recurring unit contains a quaternizable tertiary amino group, and the recurring unit B is derived from a bis-chloroformate or a diisocyanate.

摘要:
Cyan images may be prepared by the dye diffusion transfer process, using dye-releasers which on development release diffusible dyes capable of forming light-fast cyan metal-dye-complexes particularly with copper or nickel ions.

摘要:
Colored images consisting of metal-complexed azomethine dyes are prepared by chromogenic development of silver halide photographic recording materials in the presence of color couplers. The color developers contain a grouping capable of metal chelate formation adjacent to the primary amino group. The azomethine dyes are transferred into the corresponding azomethine dye/metal complexes. The complex formation is accompanied by shift of color hue and increase of light stability.
