  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 opaque 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°C at minimum to 50°C between the high and low trigger temperatures.

  本发明提供了一种热致变色不透明组合物，该组合物能够随着温度的变化而显示出透明度的变化以及颜色的变化，还提供了一种使用该组合物的层压件，以及一种利用该层压件能够隐藏和显示内部的三维物品。 热致变色不透明组合物是通过将热致变色材料分散在氯乙烯-醋酸乙烯基质树脂的小颗粒中形成的，这种材料能够通过电子捐献-接受反应显色和消色。 上述结构可随着温度的变化实现透明度的可逆变化以及颜色的变化，并具有滞后性，触发温度的高低温差最小为 10°C，最大为 50°C。
