Abstract: The invention relates to a particle with a core-shell structure, the core of which comprises at least one thermochromic semiconductor and the shell comprises at least two layers—an inner layer in contact with the core and comprising a mineral material or an organo-mineral hybrid material; and—an outer layer comprising a mineral material or an organo-mineral hybrid material, different from that of the inner layer. The invention also relates to a method for producing this particle, and the use thereof as a temperature indicator, in particular in a culinary article, such as a pan.

Abstract: Provided is an aqueous amine-free coating composition including at least one aromatic polymer, wherein the aromatic polymer is in the form of powder having a d90 less than or equal to 20 μm and in that the aqueous coating composition further includes polar aprotic solvent at a content greater than 0% by weight and less than or equal to 25% by weight. Also provided is an aqueous amine-free non-stick coating composition including such an aqueous composition for a coating, and the respective methods for producing same. Further provided is a method for producing an item on one of the faces of a metal substrate, from at least one layer of the coating composition or one layer of the non-stick coating composition.

IPC: G01K11/14

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.
