Abstract

Disclosed is a compound of the general formula ##STR1## wherein L=H or CO--(R.sup.1).sub.n (CX.sub.3).sub.m, M=alkylene, alkenylene, Q=S, Se, O, dialkylmethylene, alken-1,2-ylene, 1,2-phenylene or N-R, with M+Q together forming 3 or 4 ring members, R=alkyl, aralkyl or alkoxyalkyl, R.sup.1 is an aromatic group and X=Cl, Br or I, with n=O and m=1 or n=1 and m=1 or 2. The compounds, on exposure, eliminate HX and form free radicals and are therefore highly effective as acid donors and free radical initiators for photochemical processes.
