Abstract

We prepared UV-curable resins consisting of an aromatic urethane acrylate oligomer, an acrylate monomer, an acrylate cross-linker, and a photoinitiator; the resins were then cured by exposure to 365-nm UV irradiation for several minutes. By measuring relative photo-sensitivity, we found that the cross-linker with a functionality of four was most suitable for the photo-curable resins. Thermal, optical, and mechanical properties of UV-cured films with various compositions were evaluated, and the swelling ratio, cross-linking density, and average molecular weight between cross-linking points in the films were also quantified. The cured films showed strong resistance to chemicals, such as acidic etchant (HF) and alkaline (NaOH) solution, without peeling away from the glass substrate.
