Sensitized iodonium or sulfonium photoinitiator system comprises 1 pt. aromatic sulfonium salt or aromatic iodonium salt associated with 0.01-10 pts. fluorescent compd. selected from polyarylenes, polyarylpolyenes, 2,5-diphenyl isobenzofurans, 2,5-diarylfurans, 2,5-diarylthiofurans, 2,5-diarylpyrroles, 2,5-diarylcyclopentadienes, polyarylphenylenes, coumarins and polyaryl-2-pyrazolines. The speed of light airing is increased and softer and less expensive exposure lamps may be used effectively.
