Photographic element containing a polymeric mordant and use thereof in color image transfer.

摘要

A photographic element and its use in diffusion transfer photography are described which contain a novel polymeric mordant comprising recurring units having the formula …… wherein… A represents recurring units derived from one or more an alpha , beta -ethylenically unsaturated monomer;… B represents recurring units derived from a monomer containing at least two ethylenically unsaturated groups;… QN<+> represents a moiety containing a quaternized nitrogen group;… R<1> represents an alkoxy group having from 1 to 8 carbon atoms or an alkylenedioxy group having from 1 to 4 carbon atoms, the group being appended to an aromatic group of A;… R<2> represents an alkoxy group having from 1 to 8 carbon atoms or an alkylenedioxy group having from 1 to 4 carbon atoms, the group being appended to an aromatic group of QN<+>;… each n and m independently represents an integer from 0 to 5, with the proviso that the polymer contains recurring units having at least two alkoxy groups or one alkylenedioxy group;… each R<3> independently represents hydrogen or an alkyl group having from 1 to 6 carbon atoms;… X(-) represents an anion;… x is from 0 to 80 mole percent;… y is from 20 to 100 mole percent; and… z is from 0 to 10 mole percent.
