Outline of Final Research Achievements

We categorized photosensitive polymers as photodecomposable system after photopolymerization, photopolymerizable system after photolysis, and photocrosslinkable system after photopolymerization. Each of the systems was investigated for 3 years. In terms of photodecomposable system after photopolymerization, surface energies of resin molds were successfully controlled. In terms of photocrosslinkable system after photopolymerization, a novel methacrylate containing a chalcone unit was synthesized and the photopolymerization was controlled by the choice of photoinitiators and irradiation wavelength. In terms of photopolymerizable system after photolysis, photocrosslinkable system sensitive to 405 nm-light was successfully devised using a novel photoacid generator.
