Abstract:
An electric bulb, comprising a bulb having a glass surface, a layer comprising a fluorine-containing ethylenic polymer resin having functional group and a crystalline melting temperature formed directly on the glass surface and a layer comprising a fluorine-containing ethylenic polymer resin having no functional group applied on said layer comprising a fluorine-containing ethylenic polymer resin having a functional group,wherein said fluorine-containing ethylene resin having functional group 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 which do not have said functional group.
