Abstract

The invention relates to new arylsulfonylazides as well as the use of these compounds. The new compounds are characterized by the general formula: ##STR1## where R=aryl; x=1 or 2; and R.sup.1 and R.sup.2 are selected from H, CH.sub.3 and Cl and may be the same or different, with the provision that CH.sub.3 and Cl are not present side by side. The compounds according to the invention are suitable as photoinitiators in the preparation of relief structures by phototechniques from olefinically unsaturated polymers, as well as cross-link enhancing agents in the radical-wise cross linking of thermoplastic polymers.
