A thermoplastic laminated film

Abstract: A thermoplastic laminated film that has satisfactory adhesiveness to hydrophilic polymers, hydrophobic polymers, and inorganic substances is provided. The film comprises a base film made of thermoplastic resin and a layer formed on at least one side of said base film, wherein said layer is made of a composition comprising (a) at least one selected from the group consisting of water-soluble resins, water-­ emulsifiable resins, and water-dispersible resins, and (b) an organic boron polymer or a mixture composed of an organic boron polymer and vinyl alcohol polymer.

Description: This invention relates to a thermoplastic laminated film with excellent adhesiveness, and in particular, to a thermoplastic laminated film with excellent adhesiveness to hydrophilic polymers, hydrophobic polymers, and inorganic substances. Films made of thermoplastic resins such as polyester, polyamide or polypropylene, and especially, films made of polyester such as polyethylene terephthalate, have excellent mechanical strength, heat-resistance, resistance to chemicals, translucency, and stability of dimensions. Therefore, such films have a wide variety of uses such as for the base film for magnetic tape, insulating tape, photographic film, tracing film or wrapping film for foodstuffs. However, these thermoplastic films ordinarily have poor adhesiveness to hydrophilic polymers, hydrophobic polymers, and inorganic substances. Accordingly, when this kind of film is coated with magnetic substances, photosensitive agents or matting agents, the film surface should be treated by a corona discharge so that an anchor layer is provided. Also, when this kind of film is covered with a printed layer or a heat-sealable layer so that the film can be used for the wrapping of foodstuffs, the adhesion of the layer to the thermoplastic film is weak. Therefore, the strength of the heat seal, for example, is very weak. In addition to the above methods, for the improvement of the adhesiveness of thermoplastic films, other methods have been suggested for the treatment of the film by ultraviolet light, plasma discharge, flame treatment, corona discharge in a nitrogen atmosphere, and other physical methods. It is also possible to combine the use of these physical methods with chemical methods such as alkaline treatment or primer treatment. However, whatever the method is, the improvement achieved in the adhesiveness of the thermoplastic film is insufficient. In particular, the adhesiveness to hydrophilic polymers and hydrophobic polymers is unsatisfactory. Also, of the methods listed above, when that of primer treatment, in particular, is carried out, generally, the slipperiness of the film obtained is decreased, and therefore, operations such as rolling up of the film are made more difficult. EP-A-68 380 relates to the addition of organic boronic compounds prepared by reaction of boronic acid with polyvalent alcohols having a total of 5 or more adjacent OH-groups per boron atom and thereafter reacting with polyethylene oxide in a molar ratio of 1 - 40 relative to 1 mol of obtained borate and/or with a carboxylic acid having 8-22 carbon atoms in an amount of 3-12, particularly 3-6 % wt. relative to 100 parts by weight of magnetic pigments, particularly also of metallic powders to the grinding stock of the magnetic pigment dispersion. GB-A-1 295 877 relates to an organoboron compound having a structure, which is normally non-ionic hut may optionally assume an anionic form, and which is further characterised by its surface activity. The document also relates to a process for the production of the organoboron compound and to its application as an antistatic agent, an emulsifier and a heat-resistance improving agent for synthetic resins. The thermoplastic laminated film of this invention, which overcomes the above-discussed and numerous other disadvantages and deficiencies of the prior art, comprises a base film made of thermoplastic resin and a layer formed on at least one side of said base film, wherein said layer is made of a composition comprising (a) at least one water-soluble resin , water-emulsifiable resin or water-dispersible resin , and (b) an organic boron polymer or a mixture composed of an organic boron polymer and a vinyl alcohol polymer, said organic boron polymer being at least one of the polymers having a repeating unit I or II: wherein p is 10 to 10,000; q is 0 or 1; and when q is 1, A is -(X) ℓ -(Y) m -(Z) n -, wherein X and Z are independently hydrocarbylenes (i.e., hydrocarbon groups) with an ether linkage and containing 100 carbon atoms or less; Y is wherein R is hydrocarbylene (i.e., a hydrocarbon group) containing 1 to 34 carbon atoms, or wherein R' is hydrocarbylene containing 2 to 13 carbon atoms, and ℓ, m and n are independently 0 or 1, wherein the relative proportion by weight of (a) to (b) is 95:5 to 5:95. Accordingly, the invention described herein makes possible the objectives of (1) providing a thermoplastic laminated film that has satisfactory adhesiveness to hydrophilic polymers, hydrophobic polymers, and inorganic substances; (2) providing a thermoplastic laminated film that, in addition to the above properties, has satisfactory slipperiness, so that blocking does not take place, and handling is easy; (3) providing a thermoplastic laminated film suitable for the following uses: (a) as a base film for magnetic tape (for use in audio, video, and computer applications); (b) as a wrapping film for various kinds of goods such as foods, drugs or fertilizers (including as a base film for wrapping films on which a metal layer is deposited); (c) as a base film for films for use in plastic greenhouses in agriculture; and (d) for other general industrial uses as a base film for tracing film, as a base film for membrane-shaped switches, as a base film for stamping film (stamping foil), as a base film for adhesive tape, as a base film for films used in lettering devices (i.e., embossing devices), as a base film for OHP sheets, as name plates, as a base film for mirrors, as a base film for photoresists, as a base film for printing ribbons for use in word processors and the like, as a base film for light filters that cut off some wavelengths or some proportion of light, as a base film for layouts, as a base film for printing paper, as a film for plain paper copies, as a base sheet for white boards, and as a base film for labels, cards, and stickers for display. The organic boron polymer that has a repeating unit I or II used in the thermoplastic laminated film of this invention can be made by the following methods. (1) The following compound III or IV that has two glycerin residues at the termini of the molecule can be allowed to react with boric acid, triester of boric acid, or boric anhydride: wherein q is 0 or 1; and when q is 1, A is -(X) ℓ -(Y) m -(Z) n -, wherein X and Z are independently hydrocarbylenes with an ether linkage at their termini and containing 100 carbon atoms or less; Y is wherein R is hydrocarbylene containing 1 to 34 carbon atoms, or wherein R′ is hydrocarbylene containing 2 to 13 carbon atoms, and ℓ, m, and n are independently 0 or 1. As the triester of boric acid, esters obtained from boric acid and a lower alcohol that contains 4 or less carbon atoms can be used. Per mole of compound III or IV, 1 mole of boric acid and/or triester of boric acid is used, or 0.5 mole of boric anhydride is used. (2) By the addition of ethylene oxide, etc., to di(glycerin)borate or di(catechol)borate; or to a diol that contains a di(glycerin)borate residue or a di(catechol)borate residue, both of which have 206 or fewer carbon atoms; polyetherification is accomplished. Alternatively, equimolecular amounts of a dicarboxylic acid that contains 3-36 carbon atoms and the di(glycerin)borate, di(catechol)borate, or diol mentioned above are reacted. Instead of the dicarboxylic acid, an ester obtained from the dicarboxylic acid and alcohol with 4 or fewer carbon atoms, a halide of the dicarboxylic acid, or a diisocyanate with 4 to 15 carbon atoms may be used. In the preparative method 1 or 2, two or more of the starting materials can be used. For example, it is possible to use a combination of two or more of the compounds of the structural formula III, the compounds having different groups with regard to -{A}q-. As the organic boron polymer obtained in this way, the following compounds are included: In this invention, the vinyl alcohol polymer that is used with the organic boron polymer is as follows: Polyvinyl alcohol that is obtained by the saponification of polyvinyl acetate, in which the degree of saponification is 100 mole % and the degree of polymerization is 100-300; partially saponified polyvinyl alcohol obtained by the saponification of polyvinyl acetate, with the degree of saponification of 70 mole % or more and the degree of polymerization of 100-3000; compounds obtained by the saponification of the result of the copolymerization of vinyl esters and other monomers; derivatives obtained by the chemical modification of these compounds; etc. Partially saponified polyvinyl alcohol with a degree of saponification of 85 mole % or more and completely saponified polyvinyl alcohol with the degree of polymerization of 200 or more are particularly suitable. The organic boron polymer I or II and PVA are mixed in an aqueous solvent to form a solution or suspension of these polymers, and the solution or suspension is heated as needed. The relative proportions by weight of the organic boron polymer I or II and PVA in the mixture can be 5:95 - 95:5, and preferably 10:90 - 50:50. To specify in more detail, for example, an aqueous solution of PVA is made, and to this, the organic boron polymer I or II is added dropwise with agitation. At this time, the reaction temperature is 20-100°C, and preferably 50-80°C. In the solution of suspension, it appears that the PVA backbones are bridged to each other by the organic boron polymer.

The hydrophilic groups include phosphonic acid residues phosphinic acid residues, sulfonic acid residues ammonium groups and carboxyl group. Resins that contain the said hydrophilic groups include polyester, polyurethane, polyamide, acrylic resins, epoxy resins and polyolefin resins.

Generally, the fusion-polycondensation method is employed for the preparation of the polyester. For example, the polyester is prepared by the direct esterification method, in which the components listed above are allowed to react directly with each other to polycondense them with removal of the water that is produced. Alternatively, the ester exchange method can be employed in which the dimethyl ester of the carboxylic acid component and the glycol component are allowed to react with each other to polycondense them with the removal of the methanol that is produced. In addition to the melt-polycondensation method, it is possible to use the solution-polycondensation method or the surface-polycondensation method.

The polyurethane can be prepared from the components listed above by ordinary methods. It is also possible to use a monomer with the hydrophilic groups mentioned in the preparation of polyester so that it is incorporated into the polyurethane backbone. The acrylic resin can be prepared by the polymerization of acrylic acid or its derivatives, and monomers with vinyl groups other than acrylic acid or the derivatives thereof if needed.

Compounds shown by the formula VI-2 include styrene; o-, m-, or p-monoalkylstyrene, the alkyl group of which is, for example, methyl, ethyl, propyl, butyl, amyl, hexyl, heptyl or octyl; 2,4-, 2,5-, 2,6-, 3,4-, or 3,5-dialkylstyrene; 2,4,5- or 2,4,6-trialkylstyrene, 2,3,4,5-tetraalkylstyrene; α-substituted derivatives of styrene and the said styrene derivatives.

Among these compounds, (meth)acrylic acid, glycidyl(meth)acrylate, mono-(2-(meth)acryloyloxyethyl)acidphosphate, and hydroxyethyl(meth)acrylate are especially preferable. The acrylic resin can be prepared by ordinary methods from the monomers listed above. For example, it can be prepared by the suspension polymerization method, in which the monomers mentioned above are polymerized in an aqueous solvent in the presence of a water-soluble initiator. As the initiator, ceric ammonium nitrate, ceric ammonium sulfate, potassium persulfate, ammonium persulfate or hydrogen peroxide can be used. The polymerization reaction generally should be carried out at the temperature of 0-100°C, and preferably within the limits of 5-80°C. When the reaction temperatures are below 0°C, the rate of polymerization slows, and when the reaction temperatures are above 100°C, the initiator is decomposed; thus, stability of the reaction system declines and gelatin readily occurs. In addition to the suspension polymerization method, the solution polymerization method and the bulk polymerization method can also be used. The main components of the resin composition used in this invention are (a) at least one selected from the group consisting of a water-soluble resin, a water-emulsifiable resin, and a water-dispersible resin (hereinafter, these resins are referred to as aqueous resins), and (b) an organic boron polymer or a mixture of the organic boron polymer and the aqueous resin. The relative proportions (w/w) of the aqueous resin and the organic boron polymer or the mixture are 95/5 to 5/95, and preferably 80/20 to 20/80. When the water-type resin is less than 5% by weight, the adhesion of the film obtained to hydrophobic polymers is slightly decreased. When the amount of the organic boron polymer or the mixture is less than 5% by weight, the adhesion of the film obtained to hydrophilic polymers is slightly decreased. The composition may comprise such components as coloring agents, anti-static agents, crosslinking agents, anti-blocking agents, lubricants such as inert particles (e.g., inorganic or organic fine particles), other polymers, ultraviolet absorbents and anti-aging agents as needed, at proportions that do not change the properties of the film obtained. Examples of the anti-static agent include surfactants; particles of metal such as palladium or silver; metal oxides such as indium oxides, tin oxides; charge transfer complexes such as tetracyanoquinodimethane complex. Examples of the crosslinking agent include polyfunctional reactive compounds containing within their molecules at least two functional groups such as epoxy, aziridinyl, isocyanate or Bunte salt thereof, blocked isocyanate, alkoxy, alkylol, vinylsulfone, vinylsulfone donor, acryloyl and active hologen. Examples of the inert particle include particles of calcium carbonate, kaolin, alminum silicate, calcium silicate, silica, or crosslinked benzoguanamine resins. As the thermoplastic film (i.e., the base film) on which the layer that contains the above composition is provided, films made of polyester, polyamide, polycarbonate, polyphenylenesuifide, polyethermide, polyethersulfone, polyolefins, cellulose and derivatives thereof, PVA, acrylic resin, polyvinylchloride and derivatives thereof can be used. The most appropriate material for the base film can be selected according to the use of the laminated film that is obtained or according to need. The materials with the greatest general usefulness are films made of polyester, polyamide, polycarbonate or cellulose-type resin. The base film can be obtained by melting and extrusion processes of the thermoplastic resin or by the casting of a solution of the resin. The non-stretched film obtained can be stretched along a uniaxial direction or biaxial directions as needed, and then the above composition is applied to its surface by a method to be described below. From the point of view of causing a good adhesion between the base film and the composition, providing a laminated film with excellent slipperiness, and providing a durable laminated film, it is preferable to apply the composition to the base film that is unstretched or else stretched along a uniaxial direction, after which the whole can be stretched as needed. Biaxially oriented base film generally has a wide film width, and because the composition is applied thinly to this base film, it is necessary to speed up the movement of the film when the composition is applied, so it is somewhat difficult to apply the composition to the base film uniformly. The thermoplastic laminated film of this invention can be prepared by the following procedure. First, the composition is dissolved, dispersed, or emulsified in water or in an aqueous solvent. This is done, for example, by the method of addition of an organic boron polymer or a mixture obtained from an organic boron polymer and vinyl alcohol polymer to latex made of the aqueous resin or by the method of addition of water or an aqueous solvent to a mixture of fused state of the aqueous resin and the organic boron polymer or the mixture with kneading. As the aqueous solvent, it is possible to use, for example, a solvent that contains an organic solvent at the proportion by weight of 50% or less such as alcohols (e.g., methyl alcohol, ethyl alcohol, isopropyl alcohol) in addition to water. The purposes of including the organic solvent are to improve the ease of coating the base film with the application fluid that contains the composition, and the purpose of improving the drying of the film after the application. Because the proportion of the organic solvent is 50% by weight or less, there is no danger of the application fluid being inflammable or explosive. As an additive to the composition for the purpose of improving the operation of coating, it is recommended that substances such as fluororesins, silicone resins and surfactants are used. The application fluid containing this composition is generally applied to the surface of the base film at the amount of 0.003-5 g/m², and preferably 0.01-3 g/m². If less than 0.003 g/m² is used, the adhesiveness of the film obtained to other resins that are applied on the film is poor, and if more than 5 g/m² is used, the slipperiness and the anti-blocking properties of the film obtained are poor. In addition to the coating method in which the application fluid is prepared and coated on the base film, other methods that can be used include the extrusion coating method, extrusion laminating method, and dry laminating method and the hot-melt adhesion method. Before lamination is done by the application of the resin composition, or after such lamination is done, it is possible to treat the surface of the base film or the surface of the resin composition layer by corona discharge in the air or in a nitrogen atmosphere or by ultraviolet radiation. By the use of such treatment, the adhesiveness of the base film with the resin composition or the adhesiveness of the film obtained with other resins is further improved. In the composition used in the film of this invention, there are included an organic boron polymer that has a specific structure or a mixture of said organic boron polymer and vinyl alcohol polymer, and an aqueous resin. Therefore, said composition has satisfactory adhesion to hydrophobic polymers, hydrophilic polymers, and inorganic substances. Therefore, the thermoplastic laminated film of this invention with a layer of this resin composition has satisfactory adhesiveness to hydrophobic polymers, hydrophilic polymers, and inorganic substances. Furthermore, on the surface of the layer of the resin composition that contains the mixture and the aqueous resin, minute indentations are formed. For that reason, the slipperiness of this kind of film is satisfactory. Examples Below, this invention will be explained with reference to examples. Example 1 (A) Preparation of a thermoplastic laminated film A polyester modified with sulfonic acid with a molecular weight of about 20,000 was synthesized using 50 mole % of terephthalic acid, 45 mole % of isophthalic acid, and 5 mole % of 5-sodium sulfoisophthalate as the dicarboxylic acid components, and 80 mole % of ethylene glycol and 20% neopentyl glycol as the glycol components. This polyester was dispersed in water to the concentration of 10% by weight, and to this mixture was added the organic boron polymer I-1 (P₁=1000) at the concentration of 30% by weight with respect to said polyester. Separately, polyethylene terephthalate (PET) was extruded at the temperature of 280-300°C, and a non-stretched film 1000 µm thick was obtained by cooling of the extrudate on cooling rollers at 15°C. This non-stretched film was passed through a pair of rollers heated to 85°C that moved at different speeds, and stretched in its machine to 3.3 times of the original measurement. The dispersion mentioned above that contains a resin composition was applied to the surface of this film by use of the air-knife method and dried in a heated draft at 70°C, forming a coated layer composed of the resin composition. The film was stretched in the transverse direction by the use of tenterhooks to 3.3 times the original width at 98°C, and fixed at 200-210°C, by which means a coated polyester film stretched in biaxial directions and 100 µm thick (with a resin composition layer 0.15 µm thick) was obtained. (B) Evaluation of the thermoplastic laminated film A 10% aqueous solution of polyvinyl alcohol (a hydrophilic polymer,) and a solution of polyvinyl chloride (hereinafter referred to as PVC; a hydrophobic polymer) in 10% dimethylformamide were prepared. The solutions were colored by the addition of a red dye, and these colored solutions were used separately to print one side of the thermoplastic laminated film obtained in section A above. The colored solutions were applied to the surface of its resin composition layer at the rate of 2 g of resin/m², resulting in a red layer. The colored layer of this printed film was cut with a knife in a checkerboard pattern with incisions 1 mm apart, forming 100 squares on the film surface. The printed surface of the film was covered uniformly with adhesive tape (L-pack®, Nichiban Co.), and the tape was removed rapidly by being pulled off at a 180° angle. The surface was treated in this way for a total of three times, and the number of squares remaining on the surface was counted. The results are shown in Table 1. The evaluation of adhesion in Examples 2-19 and Comparative Examples 1-5 described below was done in the same way as in this Example. Examples 2 and 3 The same procedures were repeated as in Example 1 except that the organic boron polymers listed in Table 1 were used. The results of the evaluation of the adhesiveness of the thermoplastic laminated films obtained are in Table 1. The results for Examples 4 and 5 and for Comparative Examples 1 and 2 described below are also given in Table 1. Examples 4 and 5 The same procedures were repeated as in Example 1 except that the amount of the organic boron polymer used with respect to the polyester was changed as shown in Table 1. Comparative example 1 The same procedure was repeated as in Example 1 except that coating with a dispersion of polyester and an organic boron polymer was not done. Comparative example 2 The same procedure was repeated as in Example 1 except that the organic boron polymer was not used.

When the amount of the organic boron polymer in the resin composition was either very high or very low, the adhesiveness decreased slightly, but compared to the film of Comparative Example 1 that did not have the coated layer (i.e., the resin composition layer), adhesiveness was greater. When there was no organic boron polymer in the composition (i.e., the film in Comparative Example 2), the adhesiveness to the hydrophilic resin was decreased. Example 6 (A) Preparation of a thermoplastic laminated film A polyester modified with sulfonic acid with a molecular weight of 4000 was obtained according to the method of Example 1 except that the reaction time was shortened. Then 100 parts by weight of this polyester was dissolved in a mixture of 72 parts by weight of methyl ethyl ketone and 72 parts by weight of toluene. To this solution, 21 parts by weight of 4,4′-diphenylmethane diisocyanate and 0.05 part by weight of dibutytin dilaurate were added, and a reaction was allowed to proceed for 3 hours at 70-80°C. The solvent was evaporated off, and a dispersion in water that contained polyesterpolyurethane was obtained. To this, 50 parts by weight of an organic boron polymer (I-2; x₁ = 9, P₂ = 10) with respect to 100 parts by weight of the said polyesterpolyurethane was added, resulting in a coating liquid. With use of this coating liquid, a thermoplastic laminated film was prepared according to the method of Example 1. (B) Evaluation of the thermoplastic laminated film To the coated layer of the thermoplastic laminated film obtained in section A above, a 10% solution of cellulose acetate butylate in Methyl cellosolve containing a small amount of red dye was applied at the rate of 2 g of resin/m². Cellulose acetate butylate is commonly used for photosensitive compositions, etc. Then, the Methyl cellosolve was evaporated to form a red layer made of cellulose acetate butylate. The colored layer of this printed thermoplastic laminated film was cut with a knife in the same way as in Example 1 into a checkboard pattern with lines 1 mm apart and tested for peeling in the same way as in Example 1. All 100 squares remained. Example 7 An aqueous dispersion that contained polyester made in the same way as in Example 1 and an organic boron polymer (I-3; x₂ = 6, P₃ = 500) in the ration of 3:1 (w/w) was prepared and applied to a polyethylene naphthalate film 100 µm thick so that the layer when dried would be 0.3 µm thick. PVA or PVC was printed onto the coated surface of this thermoplastic laminated film in the same way as in Example 1, and the test of peeling was done. The results were expressed as the number of squares remaining. In all cases, all 100 squares remained.

Next, 50.1 parts by weight of the compound V-2-2 that contains phosphorus that is disclosed in this specification was added, and a reaction was again allowed to proceed for 1 hour at 220-230°C. The temperature of the reaction system was increased to 250°C over the next 30 minutes, and then pressure of the system was gradually reduced to reach 10 mm Hg 45 minutes later. Under these new conditions, the reaction was again allowed to proceed for 60 minutes. The molecular weight of the polyester diol obtained (hereinafter referred to as polyester diol A) was 2500, and the amount of phosphorus that it contained was 1600 ppm. Next, 100 parts by weight of the said polyester diol A was dissolved in a mixture of 72 parts by weight of toluene and 72 parts by weight of methyl ethyl ketone, and to the solution, 21 parts by weight of 4,4′-diphenylmethane diisocyanate and 0.05 parts by weight of dibutyltin dilaurate were added, and a reaction allowed to proceed for 3 hours at 70-80°C. (B) Preparation of a thermoplastic laminated film A mixture of 300 parts by weight of the polyurethane containing phosphorus obtained in section A above and 140 parts by weight of n-Buthyl cellosolve was stirred for about 3 hours at 150-170°C, giving a homogeneous sticky liquid. To this liquid was gradually added 560 parts by weight of water, and a homogeneous whitish dispersion in water (30% solids) was obtained after one hour. To this aqueous dispersion, 150 parts by weight of an organic boron polymer (I-6; X₅ = 200, P₆ = 10) was added, and ethyl alcohol was added to dilute the mixture, resulting in a coating liquid in which the concentration of solids was 4.5%. This coating liquid was applied to polyester film with an air knife coater, and dried in a draft heated at 120°C, resulting in a coated polyester film with a coat of 0.3 g/m². (C) Evaluation of the thermoplastic laminated film Five kinds of resins were tested for adhesiveness to the film obtained in section B. The resins were 1) carboxymethylcellulose, 2) polyvinylidene chloride, 3) polyvinyl acetate, 4) gelatin, and 5) cellulose acetate butylate. A solution of each of the resins that contained a red dye compatible with the resin was applied to the surface of the film and dried, resulting in a resin layer 3 µm thick. The resin layer obtained was cut with a knife in the same way as in Example 1 into a checkerboard pattern with lines 1 mm apart, and a test of peeling was done. The results were that adhesiveness to each of the five resins was satisfactory; the number of squares remaining were 100 for resin 1, 95 for resin 2, 100 for resin 3, 100 for resin 4, and 90 for resin 5. Example 9 (A) Preparation of acrylic resin Monomer mol% Ethyl acrylate 45 Methyl methacrylate 45 Hydroxyethyl methacrylate 6 Glycidyl methacrylate 2 Sodium vinylsulfonate 2 In a four-necked flask with a volume of 2 liters equipped with a condenser, 650 g of water, all of the sodium vinylsulfonate shown in the above table, and 1/5 of the amount of each of the other monomers were added. The total weight of the monomers were 350 g. Next, 0.85 g of dodecyl mercaptan and 0.05 g of potassium persulfate as catalyst were added. The temperature of the mixture was increased to 80°C with stirring in an atmosphere of nitrogen, and the remaining amounts of the monomers and 0.15 g of the catalyst were gradually added at the same temperature over a period of 1.5 hr. The reaction mixture was stirred for an additional 1 hour at this temperature to complete the reaction. A stable and homogeneous latex milky white in color that did not contain any emulsifier was obtained. (B) Preparation and evaluation of a thermoplastic laminated film To 1,000 parts by weight of the latex obtained in section A, 150 parts by weight of an organic boron polymer (I-1; P₁=1000) was added, and water was then added so that the total weight of the mixture was 3,000 parts by weight. This coating liquid was used as in Example 1 and the layered film obtained was evaluated as in Example 1. The number of squares remaining was 100. Example 10 To 500 parts by weight of the acrylic latex obtained in section A of Example 9, 50 parts by weight of an organic boron polymer (I-4, P₄=100) was added, and to the mixture, water was added so that the total weight of the mixture would be 1500 parts by weight. This coating liquid was applied to cellulose acetate film 75 µm thick at the rate of 0.5 g resin/m², and dried for 2 min at 80°C. This film was evaluated for adhesion in the same way as in Example 1. The number of squares remaining was 100. Example 11 An aluminum layer was deposited at the thickness of 500 Å over the surface of the coated polyester film stretched in biaxial directions obtained in section A of Example 1 by the vacuum deposition method. The aluminum layer was cut with a knife in the same way as Example 1, and a test of peeling was done. The number of squares remaining was 100. Separately, instead of the aluminum, silicon dioxide was used for deposition (800 Å thick) by the sputtering method, and testing was done by the method of Example 1. The number of squares remaining was 100. Example 12 To an aqueous solution of polyvinyl alcohol with a degree of saponification of 88% and a degree of polymerization of 500, an organic boron polymer (I-1; P₁=1000) was added so that the ration by weight of PVA to the organic boron polymer would be 1:4, and the mixture was stirred for 30 minutes at 40-50°C, giving an aqueous solution. This aqueous solution of the mixture was added to a dispersion of the polyester modified with sulfonic acid obtained in section A of Example 1 so that the weight of the mixture of the organic boron polymer and the polyvinyl alcohol would be 50% by weight with respect to said polyester, giving a coating liquid. Next, by the methods in Example 1, a PET film stretched in uniaxial direction was prepared, and the above coating liquid was applied to coat the film, after which the film was stretched as described in Example 1, giving a coated polyester film stretched in biaxial directions. This film was tested by the methods of Example 1, and the results are shown in Table 2. Furthermore, by the methods of ASTM-1894, the friction coefficient was measured. These results are shown in Table 2. Comparative Example 3 Instead of the aqueous solution containing a mixture of PVA and and an organic boron polymer, an aqueous solution of PVA (degree of saponification, 88%; degree of polymerization, 500) was used, and the other procedures were the same as those in Example 12.

When the film had a layer in which the components do not include a mixture of PVA and an organic boron polymer, or the film did not have a layer containing a resin composition, comparable results were not obtained. Example 13 A polyester modified with sulfonic acid with a molecular weight of 4000 was obtained according to the method of Example 1 except that the reaction time was shortened. Then, 100 parts by weight of this polyester was dissolved in a mixture of 72 parts by weight of methyl ethyl ketone and 72 parts by weight of toluene. To this solution, 21 parts by weight of 4,4′-diphenylmethane diisocyanate and 0.05 part by weight of dibutytin dilaurate were added, and a reaction was allowed to proceed for 3 hours at 70-80°C. The solvent was evaporated off, and a dispersion in water that contained polyesterpolyurethane was obtained. Separately, an organic boron polymer was added to an aqueous solution of PVA with a degree of saponification of 92% and a degree of polymerization of 650 to give a ratio by weight for the PVA and said organic boron polymer of 1:9, and by stirring for 30 minutes at 40-50°C, an aqueous solution was obtained. As the organic boron polymer, I-8(X₆+Z₃=100; P₈=2) was used. To the aqueous suspension of the polyester polyurethane mentioned above, this aqueous solution was added so that the ratio by weight of the polyester polyurethane and the mixture would be 100:50, resulting in a coating liquid. This was used by the methods of Example 1 to prepare a thermoplastic laminated film. The film was evaluated by the same methods as in Example 12 for adhesiveness to PVA, and for slipperiness (i.e., friction coefficient was measured). The results are shown in Table 3. Example 14 The same procedure was repeated as in Example 13 except for the use of compound I-5 (X₃=32, X₄=2, P₅=20) as the organic boron polymer.

To this liquid, 560 parts by weight of water was gradually added, resulting in a homogeneous whitish aqueous dispersion containing 30% solids after about an hour. Separately, an organic boron polymer (I-6;X₅=200, P₆=10) was added to an aqueous solution of PVA with a degree of saponification of 95% and a degree of polymerization of 300 so that the ratio by weight of PVA to the organic boron polymer would be 3:7, and the mixture was stirred for 30 minutes at 40-50°C, giving an aqueous solution. To the aqueous dispersion that contained the polyurethane was added the aqueous solution, so that the ration by weight of the polyurethane and the mixture of PVA and the organic boron polymer would be 100:150, and the mixture obtained was diluted with ethyl alcohol, resulting in a coating liquid that has 4.5% solids. This coating liquid was applied to a cellulose acetate film by the use of an air knife coater, and the film was dried in a heated draft at 100°C, resulting in a coated cellulose acetate film with a coating of 0.3 g/m². The film obtained was evaluated by the methods of Example 12 for adhesiveness to polyvinyl alcohol and for slipperiness. Results comparable to those in Example 12 were obtained. Example 17 (A) Preparation of acrylic resin The same procedure was repeated as in section A of Example 9 to obtain a latex acrylic resin.

To 1000 parts by weight of the latex obtained in section A, this aqueous solution was added so that the ratio by weight of the acrylic resin and the mixture of PVA and the organic boron polymer would be 2:1, and then water was added so that the total weight of the mixture would be 3000 parts by weight. This coating liquid was applied to a polyethylene naphthalate film, which was dried at 100°C, and further heat-treated while being stretched at 150°C. This film was then evaluated by the methods of Example 12 for its adhesiveness to PVA and for slipperiness. Results comparable to those of Example 12 were obtained.
