Photo-curable urethane (meth) acrylate according to one side of the present invention, 1,4-cyclohexanedimethanol (1,4-CHDM) high and the urethane (meth) acrylate-based index of refraction than that of the compound prepared using, it is used it is convenient to present in a liquid of low viscosity at room temperature. Further, photo-curable urethane (meth) acrylate according to one side of the present invention can reduce a rainbow effect (rainbow effect) of the cured film due to its high refractive index, and present in a liquid of low viscosity synthetic is possible on a large scale, optical path has a easy-to-use advantages in the manufacture resin composition. Further, the optical path according to one side of the present invention, chemical conversion urethane (meth) acrylate and it is possible to ensure a high refractive index can be effectively used in the photocurable resin composition is applied to the optical component material, the plastic used in the optical material film or used as a surface coating material of a substrate, has high transparency, refractive index and surface hardness of the cured product from the optical article, it may be used to indicate the naechim, productivity and excellent in heat resistance characteristics.
