LIGHT SENSITIVE, THERMALLY DEVELOPABLE IMAGING SYSTEM CONTAINING A BLEACHABLE OR LEUCO DYE, NITRATE SALT AND DIAZONIUM SALT

摘要

LIGHT SENSITIVE, THERMALLY DEVELOPABLE IMAGING SYSTEM 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 (1) a polymeric binder resin, (2) a bleachable dye or leuco dye, (3) a nitrate salt, and (4) a light sensitive diazonium salt.
