Photographic materials and process for their production |
| abstract |
The invention provides an opaque reflective photographic material eg paper whose non image side is coated with a mordant in an amount to absorb during washing of the photographic material dyes that would contribute to staining of the final image. n The mordant may be a quaternary nitrogen-containing compound, preferably a quaternized vinylimidazole polymer or vinyl benzylammonium compound. The mordant may be coated at a lay down of from 100 to 400 mg/square ft, preferably from 150 to 300 mg/square foot. The coating preferably includes a binder such as gelatin. n The products of the invention may be produced by coating the non image side of the photographic material with an aqueous composition containing the mordant and a binder using known methods. |
