Abstract:
1. A coating composition for an antireflection single coating layer comprising: a low refraction-thermosetting resin having a refractive index of 1.2 to 1.45; a high refraction-ultraviolet curable resin having a refractive index of 1.46 to 2; and an ultraviolet absorber, wherein the high refraction-ultraviolet curable resin has a continuous concentration gradient in a thickness direction of the single coating layer, wherein the single coating layer is manufactured by a curing process that involves radiating ultraviolet light and thermosetting, wherein the low refraction-thermosetting resin includes one or more compounds selected from the group consisting of a silicon alkoxide reactant that cause a sol-gel reaction, a urethane reactive group compound, a urea reactive group compound, and an esterification reactant, and wherein the high refraction-ultraviolet curable resin includes one or more monomers selected from the group consisting of acrylate monomer, urethane acrylate oligomer, epoxy acrylate oligomer, and ester acrylate oligomer.
