Claims (1)
複数の示温材料によつて形成された熱変化層を含
み、その熱変化層を前記変色境界温度の高低順が
外側から内側へ向かつて同一傾向なるように配置
した多層熱変色表示体。 It includes a heat change layer formed by a plurality of temperature-indicating materials with different color change boundary temperatures that reversibly change color development, and the heat change layer has the same tendency as the order of height of the color change boundary temperature goes from the outside to the inside. A multilayer thermochromic display arranged like this.
