Abstract (en)
[origin: WO2019197413A1] A heated aerosol-generating article (10) for use with an aerosol-generating device (510) having a heating element (520), the heated aerosol-generating article comprising a rod of aerosol-generating substrate (20); and an outer wrapper (60), wherein the outer wrapper is wrapped around at least a portion of the rod of aerosol-generating substrate and at least a portion of an outer surface of the wrapper comprises a thermal indicator (100, 101, 102, 103). The thermal indicator comprises a thermochromic material, whereby at least a portion of the thermochromic material is adapted to undergo a visual change when the temperature at said portion of the thermochromic material exceeds a threshold temperature, such that the outer wrapper provides a visual indication that the temperature at the thermal indicator has exceeded the threshold temperature, wherein the threshold temperature is at least about 175 °C.
