Abstract:
A composite material for office automation equipment which is produced by applying, to an office automation equipment substrate, a material comprising a fluorine-containing ethylenic polymer having functional group and 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 and epoxy, and (b) 70 to 99.95% by mole of any one of fluorine-containing ethylenic monomers and monomer mixtures having no functional group selected from the group consisting of tetrafluoroethylene, a monomer mixture of 85 to 99.7% by mole of tetrafluoroethylene and 0.3 to 15% by mole of a monomer represented by the formula (2): CF2=CFâ€”Rf1â€ƒâ€ƒ(2) wherein Rf1 is CF3 or ORf2, in which Rf2 is a perfluoroalkyl group having 1 to 5 carbon atoms and a monomer mixture of 40 to 80% by mole of tetrafluoroethylene, 20 to 60% by mole of ethylene and 0 to 15% by mole of a monomer copolymerizable therewith, said composite material has a non-sticking property and heat resistance of adhesion at an elevated temperature to the substrate.
