Certain polyacetylenes exhibit reversible color changes at transition temperatures in the range -180.degree. to 220.degree. C., wherein the thermochromic cycles can be repeated many times with no apparent degradation and little change in spectroscopic properties.

These thermochromic polyacetylenes are useful in temperature-indicator and indicia-display device applications.

A process for laser-beam recording of images is described employing a thermochromic polyacetylene, in which the hysteresis properties of the polyacetylene can be suitably altered allowing for selectively storing or erasing the formed image.
