ABSTRACT:
Display arrangements useful as art forms and useful in advertising applications can be constructed by coating areas of the surface of a support with differently colored compositions, each of which is capable of appearing as being of one color at one temperature and as being of another color at a different temperature. The compositions should be differently colored at at least one temperature. The color-temperature effects achieved are obtained through the use of what are termed reversible thermochromic compounds or compositions. Elements may be provided on the support for regulating the temperatures of the various areas.
