Abstract
A thermochromic laminate member capable of reversible change from a metallic luster color to a colorless state, comprises a first layer for regulating the wavelength of reflected light, composed of a metal luster pigment, which consists of natural mica surfacially covered with titanium oxide and has a grain size of 5 to 100 µm, and a film forming material; and a second layer composed of a thermochromic material, which consists of an electron donating compound, an electron accepting compound, and an organic medium enabling a reversible color-forming reaction between said compounds and has a luminocity value of 6 or lower in the colored state and a luminocity value of 8 or higher in the colorless state, and a film forming material.
