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.
Abstract (fr)
Le cout de la technologie photographique utilisant l'halogenure d'argent a augmente de maniere considerable avec les augmentations du cout de l'argent. Il serait par consequent souhaitable d'eliminer l'argent de ces materiaux photographique. De nombreux systemes de remplacement de l'argent ont tendance a etre complexes sans pour autant apporter les resultats sensitometriques equivalents a ceux des systemes utilisant un halogenure d'argent, Un nouveau systeme photographique comprend un liant contenant un nitrate et un leuco-colorant ou colorant decolorable, lequel systeme s'est revele etre un systeme thermographique efficace.
