Abstract : It is an object of the invention to provide a thermally indicating coating composition which accurately, rapidly and irreversibly shows that a certain predetermined temperature has been reached. Another object of the invention is a series of temperature indicators which may be conveniently applied to a test object, and whose visual appearance at the termination of the test will indicate the temperature limit reached during the test. Yet another object of this invention is a coated paper instantly and irreversibly responsive to a sharp but transitory upward temperature change, as, for instnace, in telegraphy or modern high speed reproduction systems, as well as in the high speed recording of electronic computation data.
