With the analysis and discussion of their photoini- liability, it was indicated that their max are all around 330 nm, and all of them have excellent solubility in water and good photoinitiability. Furthermore, the three Photoinitiators with α-tert-amine are obviously superior to the one with just α-sec-amine. Among the four photoinitiators l-(4-aminophenyl)-2-diethylamino-l- propanone dihydrochloride is the best and it has excellent use value.
