Light-sensitive diazonium trifluoromethane sulfonates

Abstract

Provided are light-sensitive diazonium compounds known as diazonium trifluoromethane sulfonates, which have the structural formula: ##STR1## wherein D --N.dbd.N-- is the cation of a light-sensitive, aromatic diazonium compound. The diazonium trifluoromethane sulfonates are prepared as the reaction product of trifluoromethyl sulfonic acid, or a salt thereof, and a diazonium compound. Said diazonium trifluoromethane sulfonates find utility in diazography formulation for both positive- and negative-working diazotype photoreproduction systems, and as latent polymerization initiators activatable by irradiation.
