| Abstract: | Visible photoinitiation systems composed of squarylium cyanine dye
and iodonium salt were studied in this work. Such systems possess a good thermostability and
high photochemical activity. Upon irradiation, the electron transfer reaction occurs between
excited dye and iodonium, leading to photobleaching of squarylium cyanine dye and cleavage
of iodonium to generate active radical. The results obtained indicated that squarylium cyanine
dye and iodonium salt combination can serve as a suitable visible photoinitiation system for
photocrosslinking of acrylates. |
