Abstract
A reflector of a lighting apparatus comprises a substrate and a coating layer located on a surface of the substrate. The coating layer is formed of a resin composition comprising an acrylic resin having at least one of a dimethylsiloxane group and a perfluoroalkyl group. Then, the coating layer is configured so that total surface free energy is less than or equal to 30 [mJ/m], and when the total surface free energy is divided into two components of a polar force component and a dispersion force component, surface free energy of the dispersion force component is less than or equal to 25 [mJ/m].
