    摘要: A new reversible heat sensitive recording composition for erasable recording is disclosed which is used as a recording or marking material that is capable of erasure at a specific temperature so that coloring or decoloring can be controlled to occur at desired temperature ranges. This range or the hysteresis value of the composition is determined by the .DELTA.T value of the contained ester compound. In addition, the composition can provide a wide variety of hues and can readily be prepared. The marking or recording drawn in this composition can be maintained at room temperature or less.

    摘要: A new reversible temperature indicating composition for use in temperature indicating instruments is diclosed which is capable of accurate temperature indication in a variety of colors and characterized by a minimum range of hysteresis so that the marking drawn in this composition can decolor at or close the temperature at which its coloring takes place. In addition, the composition can provide a wide variety of hues and can be readily prepared. These and other advantages are provided by the inclusion as a main ingredient of an ester compound having .DELTA.T value, defined .DELTA.T=melting point--clouding point, in the range under 3.degree. C., the value that determines a desirably small range of hysteresis.

    摘要: A color memory toy set has a color memory toy with surface, at least one portion of the surface being provided with a color memory temperature-sensitive color changing layer colored with a coloring material including a color memory temperature-sensitive dye exhibiting hysteresis characteristics in response to temperature change between a colored state and a colorless state or between a color (I) state and a color (II) state. The toy set also includes a writing pen for either causing an image to appear or disappear on the color memory temperature-sensitive layer by drawing the image on the layer to change the color state of the drawn portion into a first state, or for causing an image to appear or disappear on the color memory temperature-sensitive layer by drawing the image on the layer to change the color state of the drawn portion to a second state.

    摘要: A method for producing a reversible thermochromic display composed of multiple, overlapping color images. In accordance with the invention, a plurality of overlapping colored image layers are formed on a support, at least one of which layers provides a reversible thermochromic image. Each of the images on the various layers has a different visual density, and at least one reversible thermochromic image changes color at a temperature below or above a predetermined temperature and provides a color which is more intense and more easily discernible than the colors of the other ones of the images.

    摘要: A reversible thermochromic material is disclosed in the application. The material is comprised of (A) an electron-donating chromatic organic compound and (B) an acidic phosphoric acid ester compound or metal salt thereof, wherein Components (A) and (B) are contained in a weight ratio of 1:1/10 to 50 by weight. The material may also contain a third Component (C) for controlling the temperature of coloration/decoloration of the thermochromatic material. The thermochromatic material undergoes reversible metachromatism at a temperature within the range of -50.degree. C. to 120.degree. C. Furthermore, the reversible thermochromic material may be contained within microcapsules.
