To the Chemists and Physicists,

I have read in Kosar's book "Light Sensitive Systems" (1965). various
references to extending the spectral sensitivity of dichomated colloids.
One suggestion being the addition of methylene blue and p-Tolune
Sulphinic Acid, and the like.

I wonder if any member of the group has carried out any experiments to
extend the the spectral sensitiviy of gum bichromate systems, and if so
with what result?

Alex.
