Fig. 7. Polymerization profiles of TMPTA (acrylate function conversion vs. irradiation time) upon exposure to the LED@405 nm under laminate in the presence of different photoinitiating systems based on SpeedCure 938® (1% w/w) and 1-amino-4-methyl-naphthalene-2-carbonitrile derivatives (0.2% w/w). The irradiation starts at t = 10 s.
