Abstract: The purpose of the present invention is the use of (Bi1-xAx)(V1-yMy)04 in a non-stick coating for a household article so as to reduce or prevent the color change of said coating during the manufacturing process thereof, characterised in that: —x is equal to 0 or x is from 0.001 to 0.999; —y is equal to 0 or y is from 0.001 to 0.999; —A and Mare selected from 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 each other.

Abstract: The present invention relates to a coating of the surface of an electrical household appliance comprising a decoration (a) comprising a pigmentary compound B1VO4 having a ?E* in the coating greater than or equal to 11 between ambient temperature and 150° C., ?E* being defined by the formula CIE1976 in the CIELAB colour space: Formula (I): L1*, a1* and b1* characterising the values L*a*b* of said compound at ambient temperature; L2*, a2* and b2* characterising the values L*a*b* of said compound at 150° C.

Abstract: The present invention relates to a fluoropolymer-based coating of the surface of a household article comprising at least two decorations (a) and (b) arranged between or in its layers, wherein: (a) is a decoration comprising at least one thermochromic pigment composition in the form of particles consisting of a (Bi1-xAx) (V1-yMy)O4 type pigment, where: —x is 0 or x is from 0.001 to 0.999; —y is equal to 0 or y is from 0.001 to 0.999; —A and M are selected from 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 each other; and (b) is a decoration comprising a temperature reference pigment composition.

Abstract: 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.
