Abstract
The present invention relates to a cooking article a substrate having a contact surface at least partially made of metal and coated with a non-stick coating comprising at least one layer including at least one fluorocarbon resin alone or mixed with a thermostable coupling binder that is heat-resistant up to at least 200° C., the fluorocarbon resin and, if necessary, the thermostable coupling binder forming a sintered network. According to the invention, the contact surface comprises an interface layer consisting of a polymer layer formed by plasma polymerization from a precursor selected from among unsaturated carboxylic acids, the salts or esters thereof, saturated carboxylic acid vinyl esters, unsaturated dicarboxylic acids, the salts, esters, hemiesters or anhydride esters thereof, and unsaturated epoxides.
