Fluoropolymer-based coating comprising a temperature indicator

A household article comprising a substrate, completely or partially covered with a coating comprising one or more primer coats comprising a fluoropolymer applied onto the substrate and at least two decorations (a) and (b) arranged on said primer coats:

• (a) a decoration comprising at least a thermochromic pigment composition in the form of particles consisting of a (Bi1-xAx) (V1-yMy) O4 type pigment in which
• x is equal to 0 or x is between 0.001 and 0.999,
• y is equal to 0 or y is between 0.001 and 0.999,
• A and M are chosen in the group consisting of nitrogen, phosphorus, an alkali metal, an alkaline earth metal, a transition metal, a poor metal, a metalloid or a lanthanide,
• A and M are different from one another,
• (b) a decoration comprising a temperature reference pigment composition;
• wherein the ΔE* of the (Bi1-xAx) (V1-yMy) O4 pigment in said coating is greater than or equal to 11 between room temperature and 150° C., ΔE* being defined by the formula CIE1976 in the CIELAB colour space:
• ΔE*=√{square root over ((L2*−L1*)2+(a2*−a1*)2+(b2*−b1*)2)}
• L1*, a1* and b1* values characterising the L*a*b* values of said compound at room temperature
• L2*, a2* and b2* values characterising the L*a*b* values of said compound at 150° C.
