This invention relates to a heating article (1) comprising a substrate (2) of which one of the surfaces (21) is equipped with a design (4), in the form of a coating layer with at least one pattern (41, 42), which comprises a thermochromic pigment composition with at least one SC thermochromic pigment that is lipid-sensitive under heat. According to the invention, the thermochromic pigment composition includes at least one thermostable pigment and composite pigment grains (43), which each include a core (430) including the semiconducting thermochromic pigment, and a solid, transparent and continuous envelope (431), formed by a mineral or organomineral material. The thermochromic pigment composition shows a reversible change in colour in a thermal colour-change area with an amplitude of no more than 40° C. within the range of variation of said temperature T1 of use.
