Photoinduced Polymerization with Samultaneous Color Formation of Fluorane Dye with Diaryliodonium Salts
Abstract:
The electron transfer occured between the excited fluorane leuco dye and diaryliodonium salt upon UV irradiation resulted in the formation of ring opening colorant and photolysis of iodonium salt, yielding active radical species. Such a system was found to be not only able to initiate the polymerization of epoxy acrylic acid, but also induce the color formation with high color density. Several diaryl iodonium salts with different chain length have been examined. Effects of chain length and counterions in diaryliodonium salts on color formation have been investigated. The colorant formed from fluorane and iodonium salt in photocrosslinked film possessed good thermal and solvent stability.
