To provide a fluorine-containing adhesive which maintains thermal resistance, chemical resistance, weather resistance and electric insulating property and has strong adhesive property directly to substrates particularly metal and glass, and an adhesive film and laminated article which are obtained by using the fluorine-containing adhesive. There is used a fluorine-containing ethylenic polymer having hydroxyl which is prepared by copolymerizing 0.05 to 30% by mole of at least one of fluorine-containing ethylenic monomers having hydroxyl and 70 to 99.95% by mole of at least one of fluorine-containing ethylenic monomers copolymerizable with the above-mentioned monomer.
A fluorine-containing adhesive comprising a fluorine-containing ethylenic polymer having hydroxyl and prepared by copolymerizing:

The present invention relates to a fluorine-containing adhesive which can be adhered firmly to various substrates of inorganic and organic materials, and relates to an adhesive film and laminated article which are produced by using the adhesive.
Hitherto fluorine-containing polymers have been used for various applications because of their excellent thermal resistance, chemical resistance, weather resistance, surface characteristics (low friction property) and electric insulating property.
On the contrary fluorine-containing polymers are generally insufficient in mechanical properties and dimensional stability, and high in price.

The fluorine-containing ethylenic polymer used for the fluorine-containing adhesive of the present invention is a fluorine-containing ethylenic polymer having hydroxyl, particularly a fluorine-containing ethylenic polymer prepared by copolymerizing:
(a) 0.05 to 30% by mole of at least one of fluorine-containing ethylenic monomers having hydroxyl and
(b) 70 to 99.95% by mole of at least one of fluorine-containing ethylenic monomers having no functional group and being copolymerizable with the component (a).
