ABSTRACT:
A novel class of compounds is disclosed of the formula ##SPC1##
Wherein R.sub.1 and R.sub.2 are lower-alkoxy or di(lower-alkyl)amino and R.sub.1 can be hydrogen and R.sub.3 and R.sub.4 are hydrogen, lower-alkoxy or di(lower-alkyl)amino and n is an integer from 1 to 5. The compounds are sensitizers for photosensitive compounds particularly polymers containing sulfonazido groups as the light-sensitive moiety.
