reviewed their work on
a non-silver halide system. They have a non-diazo type
material, dry, heat developable. It is sensitive in the
visible region to about 6000 A and has a speed on the
order of ASA 1/10. They can produce either a negative
or a positive depending on how they combine heat and light.
This work is in its early stages and the samples they
had were not of very high quality. The D is about max 0.9.
Il asked if there were any way of using reflected light
or rear projection viewing which would eliminate energy
absorption b the film which heats up the film in the gate.
I Istated reflection could not be used for high
resolution but dispersion might be. He thought it might
be possible to bleach the silver to a translucent silver
salt which would disperse the transmitted light out of
the viewing path.
indicated he would consider the possibility
turther and perhaps do a little experimental work, but
I have not heard anything further from him.
