    摘要： POLYMERS COMPRISING UNITS REPRESENTED BY THE FORMULA:

    1-(R3-Q(-R4)-(R2)M-NH-CO-(NH)N-),2,5-DI(O=),3-R0,4-R1-

    PYRROLIDIN-3,4-YLENE

    WHEREIN R0 AND R1 EACH REPRESENT HYDROGEN ATOMS OR ALKYL GROUPS, AND R3 AND R4 ARE EACH A LOWER ALKYL GROUP OR R3 AND R4 CAN TOGETHER WITH Q REPRESENT THE ATOMS NECESSARY TO FORM A TERTIARY NITROGEN-CONTAINING HETEROCYCLIC GROUP; R2 REPRESENTS AN ALKYLENE GROUP, N IS 0 OR 1, M IS 0 OR 1, AND Q REPRESENTS A NITROGEN ATOM OR A CARBON RADICAL, WITH THE PROVISO THAT R3 AND R4 ARE TAKEN TOGETHER WITH Q TO REPRESENT A TERTIARY NITROGEN-CONTAINING HETEROCYCLIC GROUP WHEN Q IS A CARBON RADICAL, AND M CAN BE 0 ONLY WHEN Q IS A CARBON RADICAL. IN ONE ASPECT POLYMERS CONTAINING THE UNITS DEFINED ABOVE CAN BE MADE BY REACTING POLYMERS COMPRISING UNITS OF MALEIC ANHYDRIDE WITH A COMPOUND REPRESENTED BY THE FORMULA:

    R6-OOC-(NH)N-NH2

    WHEREIN R6 IS A HYDROCARBON OF 1 TO 12 CARBON ATOMS AND N IS AN INTEGER OF 0 TO 1.

    摘要： A photographic color diffusion transfer element is disclosed wherein said element comprises a single dimensionally stable support, wherein said support comprises an opaque and light reflecting layer, and coated thereon in reactive association and in sequence (1) a mordant layer for binding diffusible dyes, (2) a stripping layer, (3) one or more layers comprising radiation sensitive silver halide, a solid particle dispersion of a diffusible-dye forming compound, or radiation sensitive silver halide and a solid particle dispersion of a diffusible-dye forming compound, and (4) a barrier layer comprising a polymer that (a) allows the passage of solutions for processing said element when said element is contacted with an external processing bath and (b) blocks the diffusion out of said element of the diffusible dye formed from said solid particle dispersion of a diffusible-dye forming compound when said element is contacted with an external processing bath. A further embodiment of a photographic color diffusion transfer element is disclosed wherein said element comprises a single dimensionally stable transparent support, and coated thereon in reactive association and in sequence (1) a mordant layer for binding diffusible dyes, (2) an opacifying light reflecting layer, (3) one or more layers comprising radiation sensitive silver halide, a solid particle dispersion of a diffusible-dye forming compound, or radiation sensitive silver halide and a solid particle dispersion of a diffusible-dye forming compound, and (4) a barrier layer comprising a polymer that (a) allows the passage of solutions for processing said element when said element is contacted with an external processing bath and (b) blocks the diffusion out of said element of the diffusible dye formed from said solid particle dispersion of a diffusible-dye forming compound when said element is contacted with an external processing bath. In addition, another embodiment of a photographic color diffusion transfer element is disclosed wherein said element comprises a single dimensionally stable transparent support, and coated thereon in reactive association and in sequence (1) one or more layers comprising radiation sensitive silver halide, a solid particle dispersion of a diffusible-dye forming compound, or radiation sensitive silver halide and a solid particle dispersion of a diffusible-dye forming compound, (2) an pacifying light reflecting layer, (3) a mordant layer for binding diffusible dyes, and (4) a barrier layer comprising a polymer that (a) allows the passage of solutions for processing said element when said element is contacted with an external processing bath and (b) blocks the diffusion out of said element of the diffusible dye formed from said solid particle dispersion of a diffusible-dye forming compound when said element is contacted with an external processing bath.
