Beschreibung
Zusammenfassung:	The invention relates to a coating comprising at least one functional decorative layer. The decorative layer comprises a thermochromic composition exhibiting a reversible variation of optical and/or colorimetric properties when part or all of the coating is subjected to a temperature variation between a cold temperature and a hot temperature, the cold temperature being between 0° C. and 40° C. and the hot temperature being between 80° C. and 400° C., and comprising at least one thermochromic compound of the family of silver halides. The invention also relates to a functional decorative layer composition, to an article comprising the coating or the decorative layer composition, and to the use of the coating or the decorative layer composition as a temperature indicator.
