The present invention relates to a non-stick coating comprising at least one functionalized decorative layer comprising a material having a reversible change when the coating is subjected to a temperature change of cold temperature 0°C-40°C and hot temperature 80°C-400°C Pigment compositions with optical and/or chromatic properties. Also according to the invention, the pigment composition comprises at least one compound in particle form of the formula Y (3-x) MxFe ( 5-y) QyO12 , wherein M is selected from the group consisting of lanthanides, alkali metals, alkaline earths Metals and metalloids with a degree of oxidation (DO) of +3, Q selected from the lanthanides, nonmetals with a degree of oxidation of +4, metals with a DO of +3 or +4, transition metals with a DO of +2 or +4 , alkaline earth metals and alkali metals, wherein x is 0‑0.3 and y is 0‑3. |
