Abstract: 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 color in a thermal color-change area with an amplitude of no more than 40° C. within the range of variation of said temperature T1 of use.

Abstract: The present disclosure relates to a culinary article including a metal substrate having a concave inner face intended to be placed on a side in which food can be introduced into the article and a convex outer face intended to be placed facing a heat source. The inner face being coated in succession, starting from the substrate, with a hard enamel base, which is rough and contains no lead or cadmium, and then with a non-stick coating covering the hard layer. The present disclosure also relates to a method of manufacturing such an article.

Abstract: An article comprising a metal support with two opposing faces at least one of which is covered by a discontinuous ceramic coating. Said coating has a softening point above the melting point of the support and has at least one absorbing element for the laser radiation at a wavelength of the order of 1 ?m, being at least 1% of the weight of said coating. The invention further relates to a method for producing said article.

Abstract: The invention relates to a non-stick coating with improved resistance to scratching, comprising at least one first base coat applied to a support and covered by one or several top coats based on Fluorocarbon resin. The base coat comprises the following expressed as a percentage of dry matter measured in relation to the overall composition: 9-15% by weight fluorocarbon resin, 4-5% by weight polyamide imide resin (PAI), 12-1.1% by weight polyetherethercetone (PEEK), the remainder consisting of technological additives, inert charges and dispersive media. The invention also relates to a culinary item provided with the coating.

Abstract: A cooking utensil has a teflon-coated metal support which coating is designed to form at least the inner surface of the cooking utensil and comprises at least one layer, which layer includes a fluorocarbon resin, alone or mixed with a second heat-stable resin resistant to at least 200° C. The at least one layer comprises a mineral compound resistant to temperatures higher than the sintering temperature of the resin(s) and has antimicrobial properties.

Abstract: A heating appliance, such as a cooking container, has an inside surface coating including a decoration which changes color as a function of temperature. A decoration based on a thermostable resin and a chemical substance which changes color as a function of temperature is applied over a fluorocarbon resin coating on the inside of the container.
