In this study, we aim to develop UV-curable eco-friendly materials using Isosorbide with UV stability and Poly(trimethylene ether) glycol with elasticity. The synthesized polyurethane acrylate was qualitatively analyzed by FT-IR and their molecular weight were observed using GPC. Photo-curing kinetics according to the content of the photoinitiator was confirmed through photo-DSC and we prepared cross-linked films by Dual types of UV-IR irradiator. Furthermore, the transmittance was observed through UV-vis, and the pencil hardness was measured to confirm their film properties.
