New series of diazonium salts and iodonium salts, which show practical level of sensitivity and stability as an IR sensitive photoinitiator for CTP plates, are developed. We investigated the substituent effect on the pheny group adjacent to diazonium or iodonium group. The results show 2,4,6-trialko...
