    摘要： PURPOSE: A urethane acrylate is provided to form a coating and molding material with high refractive index which is combined with improved DE values, thereby being suitable as a starting material for preparing planar waveguide or holographic recordable materials. CONSTITUTION: A urethane acrylate has a structure represented by chemical formula I. In the chemical formula I, R^1, R^2, R^3, R^4 and R^5 are independently a substituent selected from the group consisting of hydrogen, halogen, C1-6-alkyl, trifluoromethyl, C1-6-alkylthio, C1-6-alkylseleno, C1-6-alkyltelluro, and nitro group; R^6 and R^7 are independently a substituent selected from the group consisting of hydrogen and C1-6-alkyl; and A is a saturated or unsaturated, or linear or branched C1-6-alkyl radical, or a polyalkylene oxide radical having 2-6 ethylene oxide or propylene oxide units.
