eng	New Thermochromic Coatings for High Temperatures	Paper presents thermochromic coatings utilising aggregachromic colourants with different commonly used polymer coatings. Prepared thermochromic coatings based on melamine-formaldehyde or epoxide resins show the irreversible colour change and can be used for visual indication that the monitored tem perature exceeded a limit above 150 °C, either immediately or later in time and with a possibility of time dependence, while thermochromic coatings based on silicone resins show the partly reversible colour change with almost linear dependence on temperature to 350 °C and thus can be used for indication of the current temperature.
