A coating method for a clad steel in which stainless sheets are combined on adjacent surfaces of an aluminum sheet may include preparing the clad steel, preparing a coating solution in which an epoxy resin and titanium dioxide (TiO.sub.2) powder are combined in an acrylic resin, etching the clad steel to improve adhesion property between the coating solution and the clad steel, heating the clad steel, and performing electrodeposition by immersing the clad steel in the coating solution.

Provided is a thermal barrier film having, dispersed in a resin matrix, high-refractive-index particles having a D-line refractive index of 2.5 or more and 3.2 or less. The high-refractive-index particles have an average particle size of 2.0 μm or more and 5.0 μm or less. Provided are a thermal barrier film that reduces a temperature rise due to sunlight by virtue of having a high reflectance even as a thin film, has high film thickness accuracy, and has high abrasion resistance, a thermal barrier paint for forming such thermal barrier film, and an optical instrument including such thermal barrier film.
