A thermochromic opaque/transparent composition is capable of exhibiting change in transparency together with change in color in response to temperature variation, a laminate member employing the same, and a three-dimensional article capable of concealing and revealing the interior, utilizing the laminate member. A thermochromic opaque/transparent composition is composed of dispersion, in vinyl chloridevinyl acetate copolymer matric resin, which has been obtained by blending with hindered amine compound selected from piperidine derivatives within a particle size range of 0.1 to 2.0 .mu.m, of a reversible thermochromic material consisting of (a) an electron-donating color-developing organic compound, (b) a compound having a phenolic hydroxyl radical, and (c) a homogeneous fused composition containing a compound selected from alcohols, esters, ketones and carboxylic acids, and capable of exhibiting reversible change in transparency together with change in color in response to temperature variation, with hysteresis with a temperature difference of 10.degree. C. to 50.degree. C. between the low and high trigger temperatures.

There are provided a thermochromic opaque composition capable of exhibiting change in transparency together with change in color in response to temperature variation, a laminate member employing the same, and a three-dimensional article capable of concealing and revealing the interior, utilizing the laminate member. The thermochromic oaque composition is formed by dispersing a thermochromic material, capable of developing and erasing color by an electron donating-accepting reaction, in small particles in vinyl chloride-vinyl acetate matrix resin. The above-mentioned structure realizes reversible change in transparency, together with change in color, in response to temperature variation, with hysteresis with a temperature difference of 10.degree. C. at minimum to 50.degree. C. between the high and low trigger temperatures.
