Abstract
The present disclosure is drawn to an electronic device housing that can include a heat sensitive coating and a second heat sensitive coating applied to an electronic device housing. The heat sensitive coating or portion thereof can include a thermochromatic colorant having a color-changing activation temperature, and the second heat sensitive coating or portion thereof can include a second thermochromatic colorant having a second color-changing activation temperature. The color-changing activation temperature can be a temperature from 30° C. to about 100° C., and the second color-changing activation temperature can be at least 5° C. greater than the color-changing activation temperature.
Claims8
An electronic device housing, comprising:
- a heat sensitive coating applied to an electronic device housing surface, the heat sensitive coating or portion thereof comprising a thermochromatic colorant having a color-changing activation temperature;
- and
- a second heat sensitive coating applied to the electronic device housing surface, the second heat sensitive coating or portion thereof comprising a second thermochromatic colorant having a second color-changing activation temperature;
- wherein the color-changing activation temperature is at a temperature from 30 to about 100° C., and the second color-changing activation temperature is at least 5 c′e, greater than the color-changing activation temperature;
- and wherein the second color-changing activation temperature is within 10° C. of an electric device's overheated operating temperature that the housing is sized and shaped to hold therein.
