Abstract

I would like to talk about the latest example of Dry Silver technology that has led to a new product based on dry silver chemistry, but is really quite different. It is a thermal film that has similar sensitometric characteristics as dry silver. This has been accomplished by adapting dry silver chemistry to a purely thermal reaction. This technology can produce densities up to about 4, with Dmin less than .05, and it can be accomplished in microseconds using thermal heads or laser diodes, as I describe. The chemistry is similar to that used in dry silver, but the film is not light sensitive, it responds only to heat. The reaction rate for the thermal development of silver images has been adjusted so that high density can be achieved in the times available with existing thermal heads. We use silver behenate, the main ingredient of dry silver, and the same resins, but some of the other chemistry is quite different.
