OCR (Optical Clear Resin) materials are a transparent resins that are filled between the touch panel and the display. Acrylic resins not only cure quickly by UV irradiation, but also have advantages such as excellent transparency, eco-friendliness, and low cost. In this study, we synthesized and characterized an imide-based urethane acrylate (imide-UAO) derived from cycloaliphatic dianhydrides. Thereafter, a UV-curable imide-modified urethane acrylate resin composite was prepared by combining the newly synthesized imide-UAO, reactive monomer, and photoinitiator. In addition, the optical properties (yellow index, haze, and transmittance) and adhesive properties of UV-cured composites were investigated to confirm their potential as OCR materials. |
