- R.sup.4 is alkylene containing from 1 to about 3 carbon atoms;
- n is 0, 1 or 2;
- R.sup.5 and R.sup.6 are either both hydrogen or together complete a ring containing from three to six carbon ring atoms, saturated, unsaturated, or aromatic; and
- X.sup..crclbar. is an acid anion.
- 8. An imaging element, comprising:
- a support bearing a layer comprising a wash-off, light-sensitive composition comprising, in admixture,
- as a photo-hardenable material, a water-soluble, diazo resin,
- and a mordant for an anionic dye, said mordant being different from and compatible with said resin and retained by the photohardened form of the composition.
- 9. An element as defined in claim 8, wherein said mordant is a polymer with a repeating unit having the formula: ##STR98## wherein T is an organo group and constitutes a portion of a polymer backbone,
- Q is a chemical bond(s) or a chemical group linking M.sup..sym. to T;
- M.sup..sym. represents a cationic group selected from a quaternary ammonium or phosphonium group; and
- X.sup..crclbar. is an acid anion.
- 10. An element as defined in claim 8, wherein said mordant is a polymer with a repeating unit having the formula: ##STR99## wherein R.sup.2 and R.sup.3 are the same or different and each is aryl, aralkyl, or alkaryl having from 6 to less than about 20 carbon atoms, or alkyl containing from 1 to about 10 carbon atoms;
