IIRC the stabilization chemical is ammonium thiocyanate. It is used in
chromo-skedaisic (sp?) pseudo-solarization as well.

In the 70s, rapid access printing, such as Ilfoprint, was employed in
many
in-house phot-labs. There was no "fixing" of the prints (as we know it).
The "last" chemical in the processor was a stabiliser solution that made
immediate fixing for permanence... was this solution a thiocarbamide?
Prints could be fixed and washed for permanence at a later date.
I now have to wonder if this stabiliser would be a suitable candidate
for
allowing for a longer storage of lumen prints with minimal loss of the
"coloured" image without its complete loss by thiosulphate fixation.
