Abstract (en)
[origin: WO8101757A1] The cost of conventional silver halide imaging technology has increased dramatically with the rising cost of silver. It would therefore be desirable to remove the silver from such imaging materials. Many replacement systems for silver tend to be complex without providing equivalent sensitometric results to silver halide systems. A novel imaging system comprising a binder containing nitrate salt and a leuco dye or bleachable dye has been found to be an effective thermographic imaging system.
