A thermochromic laminate was provided which comprises a thermochromic layer, and a coating layer or layers laminated thereon containing a light-intercepting pigment and a light stabilizer; the coating layer or layers containing the light-intercepting pigment and the light stabilizer dispersed and fixed in a first film-forming material, and the thermochromic layer constituted of a homogeneous solid composed of an electron-donating coloring organic compound, an electron-accepting compound, and an organic compound medium for adjusting color reaction temperature dispersed and fixed in a second film forming material; the light-intercepting pigment being one or more pigments selected from metallic luster pigments, transparent titanium dioxide, transparent iron oxide, transparent cesium oxide, and transparent zinc oxide; and the light stabilizer being one or more chemicals selected from ultraviolet absorbers, antioxidants, singlet oxygen quenchers, superoxide anion quenchers, ozone quenchers, visible light absorbers, and infrared absorbers. The thermochromic laminate has remarkably improved light-fastness. |
