Polydiacetylene gel compositions, comprised of a polydiacetylene and a gel-forming liquid therefor, are described which undergo a change in color and in physical state to a solution when heated to a predetermined temperature. The gel compositions exhibit hysteresis temperature characteristics which allow the original color change to be maintained and recorded until the solution is cooled below the predetermined temperature. Thus, the gel compositions are useful in temperature-indicating devices for reversibly monitoring a wide range of temperatures. A novel class of polydiacetylene compounds is also described, useful in forming the gel compositions, formed from monomeric diacetylenediol bis(alkoxycarbonylmethylurethanes).
