Recently I was asked to give some brand names and suppliers of Diazo compounds.
The following may be outdated as they are 4-5 years old, but maybe it helps:

Product: DIAZO NEGA S 32
From: PANCHIM, 17, rue des Cerisiers, Zone industr. de l'eglantier, CE 2843
LISSES, F-91028 Evry Cedex, France, Tel.: 0033-1-6086-2828 Fax -9131.

Product: SIT C
From: FOTEC AG, Postfach 1123, Eigenheimstr. 22, CH-8700 Kusnacht, Switzerland,
Tel.: 0041-1-9303000, Fax.: 9104525.

If somebody should try to use diazo compounds: I have no information about the
concentrations needed, but would like to get informations about any experiences.
I fear the sensitizers are expensive and that with the soft negs or thin
dilutions required to make that material for line work suitable for contone,
inconsistant results may be likely to expect.
