Abstract: A fluorine-containing adhesive material comprising a fluorine-containing ethylenic polymer having a carbonate group and/or a carboxylic halide group at a chain end or a side chain of polymer, wherein a total of a number of the carbonate groups and/or carboxylic halide groups is at least 150 relative to 1 × 10 6 main chain carbons, can directly impart the firm adherability to a substrate such as a metal, a glass or a resin while maintaining excellent properties such as resistance to chemicals, resistance to solvent, weatherability and resistance to stain possessed by a fluorine-containing polymer.

Description: FIELD OF THE INVENTION The present invention relates to a fluorine-containing adhesive material which can firmly adhere to a substrate comprising an organic material such as a variety of synthetic resins or an inorganic material such as glass and metal. The present invention further relates to a laminate and a shaped article comprising the same as well as a process for producing the shaped article. RELATED ART A fluorine-containing polymer has hitherto been used in many uses since it is excellent in heat-resistance, resistance to chemicals, weatherability, surface properties (a low frictional property and the like), and electrical insulation. On the other hand, a fluorine-containing polymer is generally insufficient in the mechanical strength and dimensional stability, and is expensive. Then, in order to utilize the advantages of a fluorine-containing polymer to a maximum degree and minimize the defects, it has been extensively studied to adhere to or laminate with other organic materials or adhere to or laminate with the inorganic materials. However, a fluorine-containing polymer is inherently innert to the adhesion, and it is difficult to adhere a fluorine-containing polymer directly with the other materials (substrate). In many cases, even when the adhesion was tried with heat fusing, the adhesion strength was insufficient and, even if adhered to some extent, the adhesion strength was widely varied depending upon a type of a substrate, which resulted in the insufficient reliance on the adhesionability. As a method for adhering a fluorine-containing polymer to the other material, (1) a method for physically roughing the surface of a substrate with sandblaster treatment, (2) a method of treating the surface of a fluorine-containing polymer with sodium etching, plasma treatment, photochemical treatment or the like, and (3) a method of adhesion using an adhesive have been mainly studied. However, regarding the above-mentioned (1) and (2), a treating step is necessary and, additionally, the productivity is low due to the complicated step. In addition, a type and shape of a substrate are restricted. The adhesion strength is insufficient and a problem on appearance of the resulting laminate (coloration and flaw) easily arises. The study on an adhesive described in the above-mentioned (3) has been variously conducted. Usual adhesives based on hydrocarbon materials have the insufficient adherability and at the same time they are insufficient in the heat resistance thereof. So then, they can not withstand the conditions for adheision-processing a fluorine-containing polymer requiring molding and processing at an elevated temperature, in general, and peeling and coloration due to degradation occur. Since laminates using this adhesive are also insufficient in heat-resistance, resistance to chemicals and resistance to water of an adhesive layer, the adhesion strength can not be retained by a change in temperature and a change in circumstances, leading to the lack of reliance. On the other hand, the adhesion with an adhesive or an adhesive composition comprising a fluorine-containing polymer having a functional group has been studied. For example, there are a report on the use of, as an adhesive, a fluorine-containing polymers obtained by graft-polymerization of a fluorine-containing polymer with a hydrocarbon monomer having a carboxyl group, a carboxylic anhydride residue, an epoxy group, or a hydrolyzable silyl group, representatives of which are maleic anhydride, vinyl trimethoxysilane and the like (for example, JP-A-7-18035 (18035/1995), JP-A-7-25952 (25952/1995), JP-A-7-25954 (25954/1995), JP-A-7-173230 (173230/1995), JP-A-7-173446 (173446/1995) and JP-A-7-173447 (173447/1995)), and a report in which an adhesive composition comprising a fluorine-containing copolymer obtained by copolymerizing a hydrocarbon monomer containing a functional group such as hydroxylalkyl vinyl ether and tetrafluoroethylene or chlorotrifluoroethylene, and an isocyanate as a curing agent are used as an adhesive between vinyl chloride polymer and ETFE (ethylene/tetrafluoroethylene polymer) treated with corona discharge (for example, JP-A-7-228848 (228848/1995)). The adhesive and adhesive composition comprising a fluorine-containing polymer obtained by graft-polymerizing or copolymerizing a hydrocarbon functional monomer are insufficient in heat-resistance so that degradation and foaming are caused during a processing with a fluorine-containing resin at an elevated temperature or at the use of an elevated temperature, leading to decrease in the adhesion strength, peeling or coloration. In the case of using the above-mentioned adhesive composition described in the JP-A-7-228848 (228848/1995), the fluororesin requires corona discharge treatment. In addition, it is reported that a fluorine-containing polymer having a functional group obtained by copolymerizing a perfluorovinylether compound containing carboxylic acid or its derivative with a fluorine-containing monomer is used as an adhesive or an adhesive composition. A laminate comprising a fluorine-containing polymer having a functional group introduced by copolymerizing perfluorovinylether having carboxylic group or its derivative with tetrafluoroethylene and the like is described in U.S. Patent No. 4,916,020. This is a laminate in which the aforementioned fluorine-containing polymer having carboxylic group or the like is laminated on a metal or the other substrate via an adhesive resin such as an epoxy resin and urethane resin and not a laminate in which the polymer is directly adhered to a metal, glass or other resins. Thus, there is a problem on heat-resistance, resistance to chemicals and resistance to solvent of an epoxy resin or an urethane resin upon use. In addition, although adhesion is possible via an epoxy resin or an urethane resin, a method for adhering directly to a metal, glass or other resins is not explicitly described. SUMMARY OF THE INVENTION An object of the present invention is to solve the aforementioned problems of the prior art and provide a fluorine-containing adhesive material which can impart directly the firm adhesion strength to a substrate such as metal, glass and a resin while maintaining the excellent properties such as resistance to chemicals, resistance to solvent, weatherability, resistance to stain and unstackiness, which are general charastristics of a fluorine-containing polymer, as well as a laminate and a shaped article comprising the same. Another object of the present invention is to provide a fluorine-containing adhesive material which can firmly adhere to the above-mentioned substrate by, particularly, heat melting adhesion step, as well as a laminate comprising the same. The fluorine-containing adhesive material of the present invention comprises a fluorine-containing ethylenic polymer having the number greater than the particular number of carbonate groups and/or carboxylic halide groups at an chain end or a side chain of a polymer. The present inventors discovered that the fluorine-containing adhesive material shows a surprisingly strong adhesion strength relative to a synthetic resin, a metal, a glass, and other materials without surface treatment or coating with an adhesive resin (such as a primer) normally performed in the case of the use of a fluororesin, when the number of carbonate groups and/or carboxylic halide groups of the fluorine-containing ethylenic polymer is greater than the particular number. The present inventors further discovered that a laminate retaining the better adhesion state and a shaped article comprising the same can be obtained by selecting the particular fluorine-containing ethylenic polymer and a counterpart material, and the particular shaping conditions. The fluorine-containing adhesive material of the present invention has a carbonate group and/or a carboxylic halide group at an end or a side chain of polymer. When the material has the carbonate group, the material comprises a fluorine-containing ethylenic polymer having at least 150 carbonate groups relative to 1 × 10 6 main chain carbons. When the material has the carboxylic halide group, the material comprises a fluorine-containing ethylenic polymer having at least 150 carboxylic halide groups relative to 1 × 10 6 main chain carbons. When the material has both the carbonate group and the carboxylic halide group, the material comprises a fluorine-containing ethylenic polymer having totally at least 150 those groups relative to 1 × 10 6 main chain carbons. In the following explanation, a carbonate group and/or a carboxylic halide group are simply referred to as "carbonyl group-containing functional group" collectively. The fluorine-containing adhesive material of the present invention comprises a fluorine-containing ethylenic polymer having a carbonyl group-containing functional group at a chain end or a side chain of the polymer and the number of the carbonyl group-containing functional groups is at least 150 relative to 1 × 10 6 main chain carbons. When the number is less than 150, the sufficient adhesion strength is not manifested or, even when adhered tightly, peeling easily occurs by deformation, temperature change, or other environmental change. The number of carbonyl group-containing functional groups in the fluorine-containing ethylenic polymer of the present invention can be appropriately selected from a range of at least 150 depending on a type and shape of a substrate to be adhered, a purpose of adhesion, an application, a required adhesion strength, a form of an adhesive polymer and an adhering method. Preferably, the number of carbonyl group-containing functional groups is at least 250, more preferably at least 300 relative to 1 × 10 6 carbons. The upper limit number of carbonyl group-containing functional groups may be 3,000, preferably 2,000, for example 1,000. The too great number of carbonyl group-containing functional groups causes deterioration of heat-resistance and chemicals. The carbonate group is more preferably from a viewpoint of adhesion strength stability. The fluorine-containing adhesive material shows the better initial adhesion strength, and the better durability against temperature change (for example, the use at a low temperature or a high temperature) and permeation of water and chemicals. DETAILED DESCRIPTION OF THE INVENTION The carbonate group in the fluorine-containing adhesive polymer of the present invention is generally a group having a linkage of -OC(=O)O- and, more particularly has the structure of -OC(=O)O-R group, wherein R is a hydrogen atom, an organic group (for example, C 1 ∼C 20 alkyl group and C 2 ∼C 20 alkyl group having an ether linkage) or I, II and VII group element. Examples of the carbonate group are preferably -OC(=O)OCH 3 , -OC(=O)OC 3 H 7 , -OC(=O)OC 8 H 17 , and -OC(=O)OCH 2 CH 2 OCH 2 CH 3 . The carboxylic halide group in the fluorine-containing adhesive polymer of the present invention has specifically the structure of -COY wherein Y is a halogen element. Examples thereof are -COF and -COCl. The content of the carbonyl group-containing functional group in the adhesive material of the present invention can be measured by infrared absorption spectrometry. The fluorine-containing adhesive material comprising the fluorine-containing ethylenic polymer having these carbonyl group-containing functional groups itself can maintain the excellent properties such as resistance to chemicals, resistance to solvent, weatherability, resistance to stain and unstackiness which are the general characteristics of the fluorine-containing material, and can impart such excellent characteristics to a laminate after adhesion without lowering the characteristics. In the fluorine-containing adhesive material of the present invention, the carbonyl group-containing functional group is bonded to the chain end or the side chain of the polymer. More particularly, the fluorine-containing adhesive material comprises: (1) a fluorine-containing ethylenic polymer having only a carbonate group at a chain end or a side chain of the polymer, the number of the carbonate groups being at least 150 relative to 1 × 10 6 main chain carbons, (2) a fluorine-containing ethylenic polymer having only a carboxylic halide group at chain end or a side chain of the polymer, the number of the carboxylic halide groups being at least 150 relative to 1 × 10 6 main chain carbons, or (3) a fluorine-containing ethylenic polymer having both a carbonate group and a carboxylic halide group, the total number of these functional groups being at least 150 relative to 1 × 10 6 main chain carbons. Any of the polymers (1) to (3) may be used. The fluorine-containing adhesive material having carbonyl group-containing functional group at polymer chain end means a material having a carbonyl group-containing functional group at one end or both ends of a polymer chain. On the other hand, the fluorine-containing adhesive material having a carbonyl group-containing functional group on a side chain has the structure of a fluorine-containing ethylenic polymer obtained by copolymerizing an ethylenic monomer having a carbonate group (or a carbonate linkage) and/or a carboxylic halide group with the other fluorine-containing ethylenic monomer. Alternatively, it may have a carbonyl group-containing functional group (or linkage) at both an chain end and a side chain of one polymer. Among them, the adhesive material having carbonyl group-containing functional group at polymer chain end is preferable because heat-resistance, mechanical property and resistance to chemicals are not remarkably deteriorated and because it is advantageous in terms of the productivity and cost. In the present invention, the fluorine-containing adhesive material having carbonyl group-containing functional group at polymer chain end may comprise a molecule having a carbonyl group-containing functional group at one end or both ends of one polymer chain or may comprise a mixture of a molecule having a carbonyl group-containing functional group at one end or both ends of a polymer chain and a molecule not containing a carbonyl group-containing functional group. That is, even when the fluorine-containing polymer not containing carbonyl group-containing functional group exists in the fluorine-containing adhesive material, as long as the adhesive material has at least 150, preferably at least 250, more preferably at least 300 carbonyl group-containing functional groups relative to 1 × 10 6 main chain carbons as a whole, the adhesionability with various substrates is not deteriorated. A type and structure of the fluorine-containing ethylenic polymer (that is, fluorine-containing adhesive polymer) of the present invention are appropriately selected depending upon purpose, application and how to use. Inter alia, it is preferable that a crystal melting point or a glass transition point is at most 270° C. In particular, when the lamination is performed by heat melting adhering process, the ability of the carbonyl group-containing functional group in adhering to the substrate can be exerted maximally and the strength for adhering directly to the substrate can be imparted. In addition, preferably, when the crystal melting point or the glass transition point is at most 230° C and, more preferably at most 200° C, the further firm adhesion strength is manifested and lamination with an organic material having the relatively low heat-resistance preferably becomes possible. The fluorine-containing ethylenic polymer is a homopolymer or a copolymer having a repeating unit derived from at least one fluorine-containing ethylenic monomer. The fluorine-containing ethylenic monomer is an olefinically unsaturated monomer having at least one fluorine atom, more particularly, tetrafluoroethylene, vinylidene fluoride, chlorotrifluoroethylene, vinyl fluoride, hexafluoropropylene, hexafluoroisobutene, a monomer represented by the formula (ii). CH 2 =CX 1 (CF 2 ) n X 2 wherein X 1 is H or F, X 2 is H, F or Cl, and n is an integer of from 1 to 10, and perfluoro (alkyl vinyl ethers). In addition, the fluorine-containing ethylenic polymer of the present invention may be a copolymer having the aforementioned fluorine-containing ethylenic monomer unit and an ethylenic monomer unit having no fluorine atom. The amount ratio of the fluorine-containing ethylenic monomer unit and the ethylenic monomer unit having no fluorine atom may be from 10 to 100 mol% (for example, from 30 to 100 mol%) and from 0 to 90 mol% (for example, from 0 to 70 mol%) respectively. The ethylenic monomer having no fluorine atom is preferably selected from an ethylenic monomer having at most 5 carbon atoms so as not to deteriorate the heat-resistance and the resistance to chemicals. More particularly, ethylene, propylene, 1-butene, 2-butene, vinyl chloride and vinylidene chloride can be exemplified. Among them, a fluorine-containing ethylenic polymer involving tetrafluoroethylene unit as an essential component is preferable from a viewpoint of heat-resistance and resistance to chemicals and a fluorine-containing ethylenic polymer involving vinylidene fluoride unit as an essential component is also preferable from a viewpoint of shaping processability. In the fluorine-containing ethylenic polymer of the present invention, the crystal melting point or the glass transition point of the polymer can be adjusted by selecting a type, combination and composition ratio of the fluorine-containing ethylenic monomer. The polymer may be a resin-type or an elastomer-type. The nature of the fluorine-containing ethylenic polymer may be appropriately selected depending upon purpose and application of adhesion, and purpose and application of a laminate. Preferable examples of the fluorine-containing ethylenic polymer are: (I) a copolymer containing tetrafluoroethylene and ethylene units, (II) a polymer containing vinylidene fluoride unit, and (III) a copolymer containing units derived from tetrafluoroethylene and a monomer represented by the formula (i): CF 2 =CF-Rf 1 wherein Rf 1 is CF 3 or ORf 2 (Rf 2 is a perfluoroalkyl group having 1 to 5 carbon atoms). As the copolymer (I) containing tetrafluoroethylene and ethylene units, mentioned is a copolymer having carbonyl group-containing functional group which comprises 30 to 90 mol% (for example, 40 to 80 mol%) of tetrafluoroethylene unit, 10 to 70 mol% (for example, 20 to 60 mol%) of ethylene unit and 0 to 40 mol% of monomer unit copolymerizable therewith relative to whole monomers except for the monomer having carbonyl group-containing functional group (in the case of having carbonyl group-containing functional group at a side chain). Examples of the copolymerizable monomer are hexafluoropropylene, chlorotrifluoroethylene, a monomer represented by the formula (ii): CH 2 =CX 1 (CF 2 ) n X 2 wherein X 1 is H or F, X 2 is H, F or Cl, and n is an integer of from 1 to 10, perfluoro(alkyl vinyl ether), and propylene. Normally, one or at least two of them are copolymerized. These exemplified fluorine-containing ethylenic polymers having carbonyl group-containing functional group are preferable in that they are excellent in heat-resistance, resistance to chemicals, weatherability, electrical insulating property and untackiness. Among them, (I-1) a copolymer having carbonyl group-containing functional group which comprises 62 to 80 mol% of tetrafluoroethylene unit, 20 to 38 mol% of ethylene unit and 0 to 10 mol% of the other monomer unit, and (I-2) a copolymer having carbonyl group-containing functional group which comprises 30 to 80 mol% of tetrafluoroethylene unit, 10 to 60 mol% of ethylene unit, 10 to 30 mol% of hexafluoropropylene unit and 0 to 10 mol% of the other monomer unit are preferable in that they can maintain the excellent properties of a tetrafluoroethylene/ethylene copolymer, a melting point can be relatively low and the adhesionability to the other material can be exerted excellently. As a preferable example of the polymer (II) containing vinylidene fluoride unit, mentioned is a copolymer having a carbonyl group-containing functional group which comprises 10 to 100 mol% of vinylidene fluoride unit, 0 to 80 mol% of tetrafluoroethylene unit, and 0 to 30 mol% of at least one unit of hexafluoropropylene and chlorotrifluoroethylene relative to whole monomers except for a monomer having a carbonyl group-containing functional group (in the case of having a carbonyl group-containing functional group at a side chain). More particularly, mentioned are preferably (II-1) polyvinylidene fluoride (PVdF) having a carbonyl group-containing functional group, (II-2) a copolymer having a carbonyl group-containing functional group which comprises 30 to 99 mol% of vinylidene fluoride unit and 1 to 70 mol% of tetrafluoroethylene unit, (II-3) a copolymer having a carbonyl group-containing functional group which comprises 60 to 90 mol% of vinylidene fluoride unit, 0 to 30 mol% of tetrafluoroethylene unit, and 1 to 20 mol% of chrolotrifluoroethylene unit, (II-4) a copolymer having a carbonyl group-containing functional group which comprises 60 to 99 mol% of vinylidene fluoride unit, 0 to 30 mol% of tetrafluoroethylene unit, and 1 to 10 mol% of hexafluoropropylene unit, and (II-5) a copolymer having a carbonyl group-containing functional group which comprises 15 to 60 mol% of vinylidene fluoride unit, 35 to 80 mol% of tetrafluoroethylene unit, and 5 to 30 mol% of hexafluoropropylene unit. The fluorine-containing polymer (II) having carbonyl group-containing functional group comprising vinylidene fluoride unit is excellent in weatherability, can be shaped and processed at a low temperature and can be dissolved in a solvent and, thus, can be laminated with an organic material having the low heat-resistance. As the polymer (III), preferable are (III-1) a copolymer having a carbonyl group-containing functional group which comprises 65 to 95 mol%, preferably 75 to 95 mol% of tetrafluoroethylene unit, and 5 to 35 mol%, preferably 5 to 25 mol% of hexafluoropropylene unit, (III-2) a copolymer having a carbonyl group-containing functional group which comprises 70 to 97 mol% of tetrafluoroethylene unit, and 3 to 30 mol% of CF 2 =CFORf 2 (Rf 2 is a perfluoroalkyl group having 1 to 5 carbon atoms), and (III-3) a copolymer having a carbonyl group-containing functional group which comprises tetrafluoroethylene unit, hexafluoropropylene unit, and CF 2 =CFORf 2 (Rf 2 is as defined above) unit, wherein a total of the hexafluoropropylene unit and the CF 2 =CFORf 2 unit is from 5 to 30 mol%. These are so-called "perfluorocopolymer" and the most excellent in heat-resistance, resistance to chemicals, water repellency, untackiness and electrical insulating property among fluorine-containing polymers. The fluorine-containing adhesive material of the present invention can be obtained by copolymerizing an ethylenic monomer having a carbonyl group-containing functional group or linkage with a fluorine-containing ethylenic monomer at the ratio corresponding to a target fluorine-containing polymer. On the other hand, although various methods can be adopted in order to give a fluorine-containing adhesive material having a carbonyl group-containing functional group at a polymer molecule end, a method using a peroxide such as peroxycarbonate as an initiator can be preferably adopted from a viewpoint of economics and the quality such as heat-resistance and resistance to chemicals. As the peroxycarbonate used for introducing a terminal carbonyl group-containing functional group, preferably used are compounds represented by the following formulas (1) to (4); wherein R and R' represent a linear or branched monovalent saturated hydrocarbon group having 1 to 15 carbon atoms, or linear or branched monovalent saturated hydrocarbon group having 1 to 15 carbon atoms containing alkoxy group at an end, and R" represents linear or branched divalent saturated hydrocarbon group having 1 to 15 carbon atoms, or linear or branched divalent saturated hydrocarbon group having 1 to 15 carbon atoms containing alkoxy group at an end. Inter alia, diisopropylperoxycarbonate, di-n-propylperoxydicarbonate, t-butylperoxyisopropylcarbonate, bis(4-t-butylcyclohexyl)peroxydicarbonate, and di-2-ethylhexylperoxydicarbonate are preferable. An amount of the peroxycarbonate to be used is different depending upon a type (composition or the like) and a molecular weight of the polymer of interest, polymerization conditions, and a type of peroxycarbonate to be used and is preferably from 0.05 to 20 parts by weight, particularly from 0.1 to 10 parts by weight relative to 100 parts by weight of the polymer obtained by polymerization. An average molecular weight of the fluorine-containing ethylenic polymer may be from 3,000 to 10,000,000 (for example, from 30,000 to 1,000,000). As a method for polymerization, suspension polymerization in an aqueous medium using a fluorine-containing solvent and using the peroxycarbonate as a polymerization initiator is industrially preferable. However, other polymerization methods such as solution polymerization, emulsion polymerization and bulk polymerization can be adopted. In the suspension polymerization, a fluorine-containing solvent may be used in addition to water. As the fluorine-containing solvent used for suspension polymerization, hydrochlorofluoroalkanes (for example, CH 3 CClF 2 , CH 3 CCl 2 F, CF 3 CF 2 CCl 2 H, and CF 2 ClCF 2 CFHCl), chlorofluoroalkanes (for example, CF 2 ClCFClCF 2 CF 3 , and CF 3 CFClCFClCF 3 ), and perfluoroalkanes (for example, perfluorocyclobutane, CF 3 CF 2 CF 2 CF 3 , CF 3 CF 2 CF 2 CF 2 CF 3 , CF 3 CF 2 CF 2 CF 2 CF 2 CF 3 ) can be used. Inter alia, the perfluoroalkanes are preferable. An amount of the fluorine-containing solvent is preferably from 10 to 100% by weight relative to water from a viewpoint of suspension stability and economics. A polymerization temperature is not particularly limited and may be from 0 to 100° C. A polymerization pressure is appropriately determined depending upon a type, amount and vapor pressure of a solvent used, and other polymerization conditions such as a polymerization temperature and may be normally from 0 to 100 kgf/cm 2 G. Upon preparation of the fluorine-containing ethylenic polymer of the present invention, in order to adjust a molecular weight, the conventional chain transfer agent, for example, a hydrocarbon substance such as isopentane, n-pentane, n-hexane and cyclohexane; an alcohol such as methanol and ethanol; a halogenated hydrocarbon substance such as carbon tetrachloride, chloroform, methylene chloride and methyl chloride can be used. The content of the carbonate group at end of polymer chain can be controlled by adjusting the polymerization conditions. Inter alia, it can be easily controlled by an amount of peroxycarbonate used as an initiator, an amount of the chain transfer agent to be used and a polymerization temperature. Although a variety of methods can be adopted in order to give a fluorine-containing adhesive material having a carboxylic halide group at a polymer molecule end, for example, it can be obtained by heating and degrading (decarbonation) a carbonate group of the aforementioned fluorine-containing ethylenic polymer having the carbonate group at chain end. It is preferable that the heating is carried out so that the polymer itself becomes at least 270° C, preferably at least 280° C, particularly preferably at least 300° C although it is different depending upon a type of the carbonate group and a type of the fluorine-containing ethylenic polymer. The upper limit of a heating temperature is preferably equal to or below a thermal degrading temperature of a portion other than the carbonate group of the fluorine-containing ethylenic polymer and, more particularly, at most 400° C, particularly preferably at most 350° C. The fluorine-containing ethylenic polymer of the present invention is preferably used alone for adhesive material so as not to affect adversely the adhesionability, heat-resistance and resistance to chemicals possessed by itself. However, in such a range that its performance is not adversely affected, a variety of fillers such as inorganic powder, glass fiber, carbon fiber, metal oxide and carbon may be incorporated depending upon purpose and application. In addition, a pigment, an ultraviolet-absorbing agent and other arbitrary additive may be incorporated therein besides a filler. A resin such as another fluororesin, a thermoplastic resin and a thermosetting resin, and a synthetic rubber may be incorporated besides the above-mentioned additive and, thereby, the improvement of the mechanical property, the improvement of weatherability, the provision of design property, the prevention of static electricity and the improvement of shapability become possible. The fluorine-containing adhesive material comprising the fluorine-containing ethylenic polymer can be used as a variety of forms such as a powder, a pellet, a preformed film or sheet, a shaped article, an aqueous dispersion, an organic solvent-soluble material and an organic solvent dispersion. The better adhesion state is formed between the fluorine-containing adhesive material and the substrate by contacting the substrate with the fluorine-containing adhesive material which has been processed into a variety of these shapes, for example, at heated and pressurized state. The fluorine-containing adhesive material of the present invention can impart the firmer adhesion strength by contacting with the substrate, particularly, in the molten state. In particular, the material which can be melt-molded among the fluorine-containing adhesive materials of the present invention can be used itself as a material for shaping and can be prepared into a shaped article by the previously known method such as an injection molding, an extrusion, a coextrusion, an inflation molding, a coating, and an insert molding using a mold. Laminates having a variety of shapes such as a film, a sheet, a tube and a hose can be manufactured directly by coextrusion. In addition, a film and a sheet can be manufactured at first and the film and sheet can be laminated with the substrate to prepare a laminate. A variety of fluorine-containing adhesive polymers of the present invention as described above may also be used for treating the surface of powders or as a paint. For example, the fluorine-containing adhesive material of the present invention can be formulated into a powder, an aqueous dispersion, an organic solvent dispersion or an organic solvent solution to give a paint composition. The material of the present invention can be used as a primer for a fluorine-containing paint by utilizing the adhesion ability to a variety of substrates possessed by the polymer used for adhesive. In the present invention, the aforementioned fluorine-containing adhesive material can be shaped into a fluorine-containing adhesive film (hereinafter referred to as "adhesive film"). From a viewpoint of development of a composite material, rationalization and automation of adhesion work, and prevention of pollution, a hot melt adhesive has progressed. However, the use of an applicator is essential for general hot melt adhesives. To the contrary, a film-shaped adhesive dose not need the applicator and can be adhered by placing on a substrate or holding and hot-pressing between substrates, being also advantageous in a viewpoint of rationalization. Since a homogeneous adhesive layer is formed on the whole surface of the substrate, the uniform adhesion strength all over the surface of substrates is obtained and, thus, materials having no or worse compatibility can be dealt with. Further, the film-shaped adhesive can be used by cutting into a variety of shapes and work loss is small and work environment is better, being advantageous from a viewpoint of cost. The adhesive film of the present invention has the above-mentioned advantages similarly. The adhesive film can be manufactured by using a variety of fluorine-containing polymers depending upon the application and purpose, the film manufacturing steps, and an adhering method among the aforementioned fluorine-containing adhesive materials. Since the adhesive film itself has excellent heat-resistance, resistance to chemicals, mechanical property and untackiness, can be effectively formed into the film by, for example, a melt molding, has the better mold-processability at a relatively low temperature among fluororesins, can be formed into a thin and homogeneous film and, additionally, can be melt and firmly and smartly adhered to a variety of substrates at a relatively low temperature by a variety of thermal pressing methods, a fluorine-containing adhesive material comprising the above-mentioned copolymer (I), (II) or (III), specifically a fluorine-containing adhesive film obtained by melt molding using the above-mentioned (I-1), (I-2), (II-1), (II-2), (II-3), (II-4), (III-1), (III-2) and/or (III-3) are preferable. The thickness of the fluorine-containing adhesive film of the present invention is selected depending upon purpose and application and is not particularly limited. The thickness of the fluorine-containing adhesive film may be from 5 to 3,000 µm, preferably from 10 to 500 µm, particularly preferably from 20 to 300 µm. Too thin films require particular manufacturing methods, and are difficult to be handled upon the adhering procedures, which easily leads to crease, damage and worse appearance. In some cases, they are insufficient in respect of adhesion strength, mechanical strength, resistance to chemicals and weatherability. Too thick films are disadvantageous in respect of cost and workability upon incorporation by bonding. Further, the present invention can provide a fluorine-containing adhesive laminate film (hereinafter referred to as "adhesive laminate film") prepared by laminating: (A-1) a layer comprising the above-mentioned fluorine-containing adhesive material, and (D-1) a layer comprising a fluorine-containing ethylenic polymer having no carbonyl group-containing functional group or, if any, having less than 150 carbonyl group-containing functional groups relative to 10 6 main chain carbons. That is, one surface has the adhesionability to the substrate derived from a layer comprising a fluorine-containing ethylenic polymer having the number greater than the specified number of carbonyl group-containing functional groups, and the other surface is a layer comprising a conventional fluorine-containing polymer. The excellent properties such as resistance to chemicals, weatherability, resistance to stain, unstickiness, low friction and electrical property can be imparted to the substrate or the laminate comprising the substrate by contacting a fluorine-containing adhesive surface with the substrate and adhering them by procedures such as thermal pressing. In the adhesive laminate film of the present invention obtained by laminating layers (A-1) and (D-1), the fluorine-containing ethylenic polymer (D-1) can be specifically selected from polytetrafluoroethylene (PTFE), a tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer (PFA), a tetrafluoroethylene/hexafluoropropylene copolymer (FEP), an ethylene/tetrafluoroethylene copolymer (ETEE), an ethylene/chlorotrifluoroethylene (ECTFE), polyvinylidene fluoride (PVdF), and a vinylidene fluoride copolymer. In order to maintain and utilize the better shaping and adhesion processabilities of the adhesive laminate film of the present invention at the time of laminating the layers (A-1) and (D-1) or upon adhesion to the other material, it is preferable to select the layer (D-1) from fluorine-containing polymers having a crystal melting point or a glass transition point of at most 270° C. Thereby, the excellent properties of the aforementioned fluorine-containing polymers can be preferably imparted to the substrate or the laminate comprising the substrate. Although according to the adhesive laminate film comprising two layers of the present invention a combination of two layers can be variously selected depending upon purpose, application and a processing method, it is preferable that the adhesionability and compatibility between them are well. Specifically, the material comprising the layer (A-1) having the adhesionability among two layers is preferably selected from polymers so that a carbonyl group-containing functional group imparting the adhesionability is introduced to the polymer having the similar monomer composition as in the layer (D-1) comprising the fluorine-containing polymer. More particularly, i) a fluorine-containing laminate film obtained by laminating: (A-1) a layer comprising an adhesive material including the above-mentioned copolymer (I), and (D-1) a layer comprising a copolymer comprising tetrafluoroethylene unit and ethylene unit is preferable in that it imparts the excellent heat-resistance, resistance to chemicals and mechanical properties and is excellent in melt molding processability, and ii) a fluorine-containing laminate film obtained by laminating: (A-1) a layer comprising an adhesive material including the above-mentioned polymer (II), and (D-1) a layer comprising at least one polymer selected from the group consisting of PVdF and vinylidene fluoride copolymer is preferable in that it is excellent in weatherability and shaping processability, iii) a fluorine-containing laminate film obtained by laminating: (A-1) a layer comprising an adhesive material including the above-mentioned polymer (III), and (D-1) a layer comprising a polymer comprising 75 to 100 mol% of tetrafluoroethylene unit and 0 to 25 mol% of monomer unit represented by the formula (i): CF 2 =CFRf 1 wherein Rf 1 is CF 3 or ORf 2 (Rf 2 is perfluoroalkyl group having 1 to 5 carbon atoms) is preferable in that it is particularly excellent in heat-resistance, resistance to chemicals, untackiness and water repellency. The thickness of the adhesive laminate film of the present invention having two layers is selected depending upon purpose and application and is not particularly limited. The total thickness of two layers is from 10 to 5,000 µm, preferably from 20 to 1,000 µm, particularly preferably from 50 to 500 µm. Regarding the thickness of each layer, the adhesive layer (A-1) may be from 5 to 1,000 µm and the fluorine-containing polymer layer (D-1) may be from 5 to 4,995 µm.

For example, a functional group-containing fluorine-containing polymer of the present invention is an adhesive having the better melt mold processability at a relatively low temperature and, for this reason, the compression molding and the extrusion can be adopted. In particular, the melt extrusion is a preferable method for the reasons of productivity and quality. For preparing an adhesive laminate film of the present invention comprising two layers (A-1) and (D-1) by bonding and unifying, a method of piling each of the shaped laminate films (A-1) and (D-1) and compression molding them, a method of coating anyone on the other shaped film, and a method of bonding and unifying simultaneously with the film shaping by a multilayer coextrusion method may be adopted. Inter alia, a multilayer coextrusion method is preferable in terms of productivity and quality. Adhesion of the adhesive film of the present invention and the adhesive laminate film with the substrate is accomplished by thermal activation by heating or the like. The heat melting adhesion is preferable. In particular, the fluorine-containing adhesive of the present invention manifests the firm adhesion strength with a substrate upon heat melting adhesion. Representative adhering methods are a thermal roll method, a thermal pressing method, a coextrusion method in the case where the substrate is a thermoplastic resin, and other methods such as a high frequency heating method, a microwave method, a vacuum contact bonding method (such as vacuum pressing), and an air pressure method. The adhering method can be appropriately selected depending upon a type and shape of a counterpart substrate and a state and a type of a film. The adhesive film and the adhesive laminate film of the present invention are constructed by a variety of shapes, sizes and thickness as described above and can be used for a wide range of application due to the excellent adhesionability to a variety of substrates and the excellent properties possessed by the fluorine-containing polymer. They may be used, for example, as a tube-shaped, plate-shaped, bent plate-shaped, crooked plate-shaped film for protecting a exterior or interior decorated metal tube and bar.

A laminate 1 comprising the fluorine-containing adhesive material (A-2) of the present invention and the organic material (B-1) can be laminated with (D) a layer comprising a fluorine-containing polymer having no carbonyl group-containing functional group or, if any, having less than 150 carbonyl group-containing functional groups relative to 10 6 main chain carbons on the adhesive material (A-2) side. In this case, a fluorine-containing adhesive material used as an adhesive layer for a laminate comprising these 3 layers is preferably a material whose composition is similar to that of the fluorine-containing polymer and which has a carbonyl group-containing functional group from a viewpoint of mutual adhesionability. The thickness of the three-layered laminate may be from 25 to 10,000 µm, preferably from 40 to 4,000 µm. The thickness of the fluorine-containing adhesive material layer (A-2) may be from 5 to 2,000 µm, preferably from 10 to 1,000 µm. The thickness of the layer (D) comprising the fluorine-containing polymer having no carbonyl group-containing functional group or, if any, having less than 150 carbonyl group-containing functional groups relative to 10 6 main chain carbons is from 10 to 5,000 µm, preferably from 15 to 3,000 µm. The thickness of the organic material (B-1) is from 10 to 5,000 µm, preferably from 15 to 3,000 µm. That is, it is a laminate comprising: (A-3) a layer comprising the aforementioned fluorine-containing adhesive material, (D-2) a layer comprising a fluorine-containing polymer having no carbonyl group-containing functional group or, if any, less than 150 carbonyl group-containing functional groups relative to 10 6 main chain carbons, and (B-2) a layer comprising the aforementioned organic material, wherein the layer (A-3) is positioned between the layers (D-2) and (B-2) to give an adhesive layer, and can effectively impart the excellent properties of the fluorine-containing polymer to the organic material. In this case, the fluorine-containing adhesive material (A-3) used in an adhesive layer of a laminate 1 comprising these 3 layers is preferably a material whose composition is similar to that of the fluorine-containing polymer (D-2) and which has a carbonyl group-containing functional group in a viewpoint of mutual adhesionability. In the laminate comprising the fluorine-containing adhesive material (A-2) of the present invention, the fluorine-containing polymer (D-2) and the organic material (B-2), a suitable reinforcing agent, a filler, a stabilizer, an ultraviolet absorbing agent, a pigment and other additives can be contained in each layer in such a range that dose not deteriorate the adhesionability and the other properties of a fluorine-containing polymer. Such additives can improve heat stability, surface hardness, resistance to abrasion, weatherability, electrification and others. By the way, polyamides are excellent in high strength, high toughness and processability and are widely used for a hose, tube and pipe. On the other hand, although they are excellent also in resistance to oil, their resistance to an alcoholic solvent is less. In particular, when a gasoline containing a lower alcohol is used, the resistance to oil (resistance to gasohol) is deteriorated vigorously to cause volumetric expansion, fuel penetration and even deterioration of mechanical strength of the material. Therefore, the polyamide and the fluorine-containing polymer are laminated and, thereby, improvement of resistance to gasohol and utilization of a tube for fuel piping are sought and a variety of studies have been hitherto conducted. For example, for obtaining a laminate tube of a polyamide and ETFE by coextrusion and the like, a composition comprising a polyamide and ETFE was used as an adhesive layer (WO95/11940 pamphlet, WO96/29200 pamphlet). However, these adhesive layer materials are a composition of polyamide and ETFE and they themselves are insufficient in heat-resistance, resistance to chemicals and resistance to solvent. In addition, adhesion between a polyamide and an adhesive layer is not caused via a reaction but by only anchor effect, so that the adhesion strength is easily affected by the morphology of an adhesive layer composition. As a result, the adhesion strength easily changes at a great extent by even small change of extrusion conditions and a temperature used. The fluorine-containing adhesive material of the present invention firmly adheres to also a polyamide and, thus, can provide a laminate by which the aforementioned problems have been overcome. Therefore, a laminate tube obtained by shaping the laminate comprising a layer comprising a polyamide and a layer comprising the fluorine-containing adhesive material of the present invention into a tubular shape can be effectively utilized as a tube for fuel piping and liquid chemicals. Preferable embodiments of the laminate tube comprising the polyamide are: i) a laminate tube in which a laminate comprising: (A-4) a layer comprising a fluorine-containing adhesive material comprising the aforementioned polymer (I), and (B-3) a layer comprising polyamide is formed into a tube, wherein the layer (A-4) is an internal layer; ii) a laminate tube in which a laminate comprising: (A-4) a layer comprising a fluorine-containing adhesive material comprising the aforementioned copolymer (I), (D-3) a layer comprising ETFE, and (B-3) a layer comprising a polyamide is formed into a tube, wherein the ETFE (D-3) is an innermost layer; iii) a laminate tube in which a laminate comprising: (A-4) a layer comprising a fluorine-containing adhesive material comprising the aforementioned copolymer (II), and (B-3) a layer comprising a polyamide is formed into a tube, wherein the layer (A-4) is an internal layer; iv) a laminate tube in which a laminate comprising: (A-4) a layer comprising a fluorine-containing adhesive material comprising the aforementioned copolymer (II), (D-3) a layer comprising PVdF or VdF-based copolymer, and (B-3) a layer comprising a polyamide is formed into a tube, wherein the PVdF or VdF copolymer (D-3) is an innermost layer; v) a laminate tube in which a laminate comprising: (B-3) a layer comprising a polyamide (A-4) a layer comprising a fluorine-containing adhesive material comprising the aforementioned copolymer (I) or (II), and (B-3) a layer comprising a polyamide is formed into a tube, wherein the layer (A-4) is positioned in an intermediate layer between two polyamide layers (B-3). The similar filler, reinforcing agent and additive to those described above can be added to each layer of these laminates in such a range that does not deteriorate their objective properties. When used in fuel piping or liquid chemicals, it is preferable that a filler which imparts the electrical conductivity is added to layers ((A-4) and (D-3)) of a fluorine-containing polymer as an internal layer. A laminate tube of the present invention can be of any required shape by a variety of post-processing. For example, a necessary part such as a connector is attached to the laminate, and the laminate can be processed into L-shape or U-shape by a bend process, or can be formed into a cellular corrugate tube shape. Further, a preferable embodiment of a laminate comprising the fluorine-containing adhesive material of the present invention is a laminate comprising: (A-5) a layer comprising the aforementioned fluorine-containing adhesive material (A), and (B-4) a layer comprising an ethylene polymer. It is preferable that the ethylene polymer layer (B-4) has a functional group having the reactivity or the affinity with the aforementioned carbonate group or carboxylic halide group. More particularly, preferable examples are epoxy-modified polyethylene, an ethylene/vinyl acetate copolymer, an ethylene/vinyl alcohol copolymer, an ethylene/maleic anhydride copolymer and an ethylene/acrylic acid copolymer. These laminates can be shaped into various shapes as described above. Inter alia, when shaped into a tank shape, it can be utilized as a gasoline tank for automobiles, for which the application of a resin has been progressed recently, and fuel permeability can be improved and heat-resistance can be imparted. More particularly, examples are preferably: i) a laminate comprising: (A-5) a fluorine-containing adhesive material comprising the aforementioned polymer (I) or (III), and (B-4) an ethylene polymer, which is formed into a tank, wherein the adhesive material (A-5) is positioned on an internal layer side; and ii) a laminate comprising: (B-4) an ethylene polymer, (A-5) a fluorine-containing adhesive material comprising the aforementioned polymer (I) or (II) or (III), and (B-4) an ethylene polymer, which is shaped into a tank, wherein the layer (A-5) is positioned between two layers (B-4). Further, when a laminate comprising the fluorine-containing adhesive material of the present invention and the ethylene polymer is shaped into bottle shape, it can be used as a bottle in the field of semiconductors due to excellent resistance to chemicals of a fluorine-containing polymer. More particularly, preferable is i) a laminate comprising: (A-5) a fluorine-containing adhesive material comprising the aforementioned polymer (I) or (III), and (B-4) an ethylene polymer, which has been shaped into a bottle, wherein the adhesive material (A-5) is positioned on an internal layer side. In particular, a laminate in which the aforementioned polymer (III) is positioned in an internal layer is preferable. A process for preparing the laminate 1 of the present invention is appropriately selected depending upon a type and form of a fluorine-containing adhesive material and a type and shape of an organic material. For example, adopted are a method of preparing a fluorine-containing adhesive film using a fluorine-containing adhesive material, wrapping with an organic material and laminating by thermal activation by heating as described above; a method of preparing a fluorine-containing adhesive material paint such as an aqueous or organic solvent dispersion, an organic solvent solution, a powder, which is coated on an organic material and thermally activated by heating; an insert molding method and; when the fluorine-containing adhesive material of the present invention is laminated with a thermoplastic polymer which can be melt shapable, a coextrusion method. The laminate of the present invention can be shaped into various shapes such as a hose, a pipe, a tube, a sheet, a seal, a gasket, a packing, a film, a tank, a roller, a bottle and a container by these methods. Further, the present invention relates to a process for manufacturing a shaped laminate article which comprises shaping a fluorine-containing adhesive material (A) having a carbonyl group-containing functional group and an organic material (B) by coextrusion at a shaping temperature, that is, at such a temperature that a resin temperature at shaping exceeds a crystal melting point or glass transition point of each material. That is, since adhesion between the materials (A) and (B) and shaping into the desired shape can be accomplished at the same time and continuously by melt coextrusion, the productivity is preferably excellent and the adhesion performance is preferably better. It is preferable that in order to impart excellent interlayer adhesion strength, in the present process, the fluorine-containing adhesive material (A) and the organic material (B) are both selected from thermoplastic resins having a crystal melting point or a glass transition point of at most 270° C, preferably thermoplastic resins having a crystal melting point or a glass transition point of at most 230° C. Further, from a viewpoint of interlayer adhesion strength between the materials (A) and (B) and the better appearance of a shaped article, a shaping temperature, that is, a resin temperature at shaping is at most 300° C, preferably at most 280° C. When a shaping temperature (resin temperature) is too low, the fluorine-containing adhesive material (A) and the organic material (B) do not have sufficient fluidity, so that the sufficient adhesion between the materials (A) and (B) can not be accomplished and defective appearance such as surface roughening of a shaped article is caused. In addition, when a shaping temperature is too high, insufficient adhesion between the materials (A) and (B) and peeling are undesirably caused, foaming and surface roughening not only on the surface of a shaped article but also at an interface between the materials (A) and (B), and worse appearance such as coloration are undesirably caused. The present inventors now further discovered that a shaped article having the firm interlayer adhesion strength between the materials (A) and (B) and also the excellent appearance and quality can be prepared in the better productivity by shaping, by melt coextrusion, the fluorine-containing adhesive material (A) and the thermoplastic resin (B) having a crystal melting point of at most 230° C at a shaping temperature which exceeds a crystal melting point of each material and is at most 280° C. A second laminate of the present invention (hereinafter referred to as "laminate 2") is a laminate comprising: (A-5) a layer comprising the fluorine-containing adhesive material (A), and (C-1) a layer comprising an inorganic material. The thickness of the laminate 2 may be from 15 to 10,000 µm, preferably from 25 to 4,000 µm.
