Abstract
Composite materials for cooking apparatuses which are produced by applying, to a substrate, a material comprising a fluorine-containing polymer having an excellent adhesive property to the substrate without necessitating complicated steps and are excellent in heat resistance, non-sticking property, stain-proofing property, water- and oil-repelling property, stain-removing property, chemical resistance, rust-preventing property, antibacterial property, resistance to energy ray and abrasion resistance. The composite materials for cooking apparatuses are produced by applying, to the substrate, the material comprising a fluorine-containing ethylenic polymer having functional group which is prepared by copolymerizing (a) 0.05 to 30% by mole of at least one of fluorine-containing ethylenic monomers having at least one functional group selected from the group consisting of hydroxyl, carboxyl, a carboxylic salt group, a carboxylic ester group and epoxy, and (b) 70 to 99.95% by mole of at least one of fluorine-containing ethylenic monomers having no functional group mentioned above.
