An imaging member comprising a support, and an imaging layer, said layer further comprising catalytic centers chosen from the group consisting of metal and metal salts wherein said imaging member is substantially free of photosensitive silver halide.
A method of imaging comprising:
- supplying a catalyst chosen from the group consisting of metal and metal salts to an imaging member, said member comprising a support having an imaging layer and being substantially free of photosensitive silver halide;
- supplying an oxidant to said member;
- applying a soluble dye forming coupler to said member;
- and
- applying a developer solution to said member;
- wherein at least one of the developer and coupler is applied in an imagewise fashion.
An imaging article comprising a vehicle chosen from the group consisting of a paper and a colloid, said vehicle having catalytic centers chosen from the group consisting of metal and metal salts wherein said imaging article is substantially free of photosensitive silver halide.
A method of imaging comprising:
- supplying a catalyst chosen from the group consisting of metal and metal salts to an imaging article, said article comprising a vehicle chosen from the group consisting of a paper and a colloid and being substantially free of photosensitive silver halide;
- supplying an oxidant to said member;
- applying a soluble dye forming coupler to said member;
- and
- applying a developer solution to said member;
