Description

Polymers, water- and oil-repellent compositions, coatings, and articles 【0001】 The present invention relates to polymers, and more specifically to polymers having hydrocarbon-terminated monomer compounds as monomer components and not containing fluorine atoms in their structure, which can form a film with excellent water-repellent and oil-repellent properties; a water-repellent and oil-repellent composition comprising the polymer and a solvent; a film formed by the water-repellent and oil-repellent composition; and an article having the film on the surface of a substrate. 【0002】 Conventionally, fluorine-based coating agents containing fluorine compounds have been applied to substrates to impart water-repellent and oil-repellent properties. Such fluorine-based coating agents are generally manufactured by polymerizing or copolymerizing monomers having fluoroalkyl groups. 【0003】 On the other hand, fluorine-containing compounds, such as perfluorooctanoic acid (PFOA), tend to be highly resilient and bioaccumulative in nature. Therefore, in recent years, a wide range of fluorine-containing compounds have been categorized as per / polyfluoroalkyl compounds (PFAS), and it is predicted that restrictions on their use, sale, and discharge will be strengthened under PFAS regulations. Consequently, there is a growing demand for non-fluorine coating agents that do not contain fluorine atoms. 【0004】 Conventionally, non-fluorinated coating agents include long-chain acrylic resins having linear or branched aliphatic hydrocarbon groups. For example, Patent Document 1 (Japanese Patent Application Publication No. 2015-120894) discloses a coating agent comprising an acrylate monomer having a long-chain aliphatic hydrocarbon group and a non-fluorinated copolymer having repeating units derived from an acrylate monomer having a cyclic hydrocarbon group. Patent Document 2 (Japanese Patent Application Publication No. 2017-165872) discloses a coating agent comprising an acrylate monomer having a long-chain aliphatic hydrocarbon group and a non-fluorinated copolymer having repeating units derived from a halogenated olefin monomer. 【0005】Further, as a fiber treatment composition containing no fluorine-based compound, Patent Document 3 (Japanese Patent Application Laid-Open No. 2018-510234) discloses a composition containing at least one isocyanate-reactive oligomer and at least one polyisocyanate as essential components. 【0006】 However, none of them have demonstrated sufficient effects particularly with respect to oil repellency. 【0007】 Japanese Patent Application Laid-Open No. 2015-120894 Japanese Patent Application Laid-Open No. 2017-165872 Japanese Patent Application Laid-Open No. 2018-510234 【0008】 The present invention has been made in view of the above circumstances, and an object thereof is to provide a polymer capable of forming a film exhibiting excellent water and oil repellency without containing a fluorine atom, a water and oil repellent composition containing the polymer and a solvent, a film formed by the water and oil repellent composition, and an article having the film on a substrate surface. 【0009】 As a result of intensive studies to solve the above object, the present inventors have found that a polymer having a hydrocarbon terminal group-containing monomer compound (α) represented by the following general formula (1) as a monomer component and not containing a fluorine atom in its structure can form a film having excellent water repellency and oil repellency, and thus have completed the present invention.

[16] An article having the film according to

[15] on its surface. 【0011】The polymer of the present invention can form a film exhibiting excellent water-repellent and oil-repellent properties despite not containing fluorine atoms. Therefore, this polymer is useful as a water-repellent and oil-repellent agent composition for imparting water-repellent and oil-repellent properties to a substrate surface, without being subject to restrictions such as those imposed by PFAS regulations. 【0012】 In the present invention, "acrylic compound" is a general term for compounds having an acryloyl (hereinafter also called acrylic) group or an α-substituted acryloyl (hereinafter also called α-substituted acrylic) group. In the present invention, "(meth)acrylate" refers to either or both acrylate and methacrylate, "(meth)acrylic group" refers to either or both an acrylic group and a methacryloyl (hereinafter also called methacrylic) group, and "(meth)acrylate halide" refers to either or both acrylic acid halide and methacrylate halide. 【0013】 [Polymer] The polymer of the present invention is characterized in that it has a hydrocarbon terminal group-containing monomer compound (α) represented by the following general formula (1) as its monomer component (having repeating units formed from the hydrocarbon terminal group-containing monomer compound (α) represented by the following general formula (1)), and does not contain a fluorine atom in its structure. [In the formula, X is a monovalent organic group having a branched structure in which two monovalent hydrocarbon groups having 10 to 40 carbon atoms are bonded to the same atom, and Y is a single bond, or the following formula] * -O- ** * -C (=O)- ** * -O-C(=O)- ** * -C(=O)-O- ** * -C(=O)-NH- ** * -NH-C(=O)- ** * -OC(=O)-NH- ** * -NH-C(=O)-O- ** * -NH-C(=O)-NH- **(In the formula, * is bonded to X in general formula (1), and ** is bonded to Z in general formula (1).) A divalent organic group represented by either of the above, where Z is a single bond, or a divalent hydrocarbon group having 1 to 20 carbon atoms that may contain one or more atoms selected from oxygen, sulfur, nitrogen, and silicon atoms, and V is a monovalent hydrocarbon group having 2 to 20 carbon atoms that contains a polymerizable carbon-carbon double bond that may contain oxygen and / or nitrogen atoms. 【0014】 The polymer of the present invention does not contain fluorine atoms in its structure. As a result, it exhibits lower persistence and bioaccumulation in nature compared to conventional fluorine-based compounds. 【0015】 The polymer of the present invention must have a monomer compound (α) containing hydrocarbon terminal groups having a branched structure in which two monovalent hydrocarbon groups having 10 to 40 carbon atoms are bonded to the same atom as its monomer component. Two monovalent hydrocarbon groups having 10 to 40 carbon atoms bonded to the same atom have high packing properties. As a result, the film formed from the polymer forms a hard layer by exposing the -CH3 group, which has a low surface energy, on the surface due to the packing of hydrocarbon chains. As a result, the resulting film exhibits excellent water and oil repellency. Furthermore, in this polymer, the above-mentioned monovalent hydrocarbon groups segregate on the surface of the film, so even when a copolymer is used instead of a homopolymer, the resulting film exhibits excellent water and oil repellency. In this invention, "packing properties" refer to the ease with which multiple hydrocarbon chains can be oriented in one direction and densely on the surface of the film. 【0016】 [Hydrogen-terminated monomer compounds (α)] Hydrocarbon-terminated monomer compounds (α) are represented by the following general formula (1). [In the formula, X is a monovalent organic group having a branched structure in which two monovalent hydrocarbon groups having 10 to 40 carbon atoms are bonded to the same atom, and Y is a single bond, or the following formula] * -O- ** * -C (=O)- ** * -O-C(=O)- ** * -C(=O)-O- *** -C(=O)-NH- ** * -NH-C(=O)- ** * -O-C(=O)-NH- ** * -NH-C(=O)-O- ** * -NH-C(=O)-NH- ** (In the formula, * is bonded to X in the general formula (1), and ** is bonded to Z in the general formula (1).) It is a divalent organic group represented by any of them, Z is a single bond or a divalent hydrocarbon group having 1 to 20 carbon atoms which may contain one or more selected from an oxygen atom, a sulfur atom, a nitrogen atom and a silicon atom, and V is a monovalent hydrocarbon group having 2 to 20 carbon atoms containing a polymerizable carbon-carbon double bond which may contain an oxygen atom and / or a nitrogen atom. ] 【0017】 In the above formula (1), X is a monovalent organic group having a branched structure in which two monovalent hydrocarbon groups having 10 to 40 carbon atoms are bonded to the same atom. If the number of carbon atoms is less than the above upper limit value, the compatibility becomes good when a water and oil repellent composition containing a polymer and a solvent is used. If it is greater than the above lower limit value, the packing property of the hydrocarbon chain is enhanced, and the water and oil repellency can be sufficiently exhibited. 【0018】 As the monovalent hydrocarbon group having 10 to 40 carbon atoms, it is more preferably a monovalent hydrocarbon group having 10 to 30 carbon atoms, and particularly preferably a monovalent hydrocarbon group having 12 to 30 carbon atoms. When the number of carbon atoms is within the above range, the compatibility when a water and oil repellent composition containing a polymer and a solvent is used and the water and oil repellency of the obtained film can be made compatible at a high level. 【0019】 The monovalent hydrocarbon group having 10 to 40 carbon atoms may be linear, branched or cyclic, but is particularly preferably linear because the packing property of the hydrocarbon chain is further enhanced. Examples of the monovalent linear hydrocarbon group having 10 to 40 carbon atoms include n-decyl group, n-undecyl group, n-dodecyl group, n-tetradecyl group, n-pentadecyl group, n-hexadecyl group, n-heptadecyl group, n-octadecyl group, n-docosyl group, n-triacontyl group and the like. 【0020】 In the above formula (1), it is more preferable that two monovalent hydrocarbon groups having 10 to 40 carbon atoms bonded to the same atom are the same. When two monovalent hydrocarbon groups having 10 to 40 carbon atoms bonded to the same atom are the same, the packing property of the hydrocarbon chain is further enhanced due to the increased symmetry of the structure, and the water and oil repellency can be further exhibited. 【0021】 As X, the following formula (In the formula, R 1 , R 2 , R 3 , R 4 are each a linear, branched or cyclic monovalent hydrocarbon group having 10 to 40 carbon atoms, m is an integer of 0 to 10, and * is a bond that binds to Y in the general formula (1).) It is particularly preferable that it is a group having a branched structure represented by any of them. When X is a group having a branched structure represented by any of the above, the compatibility of the water and oil repellent composition containing the polymer and the solvent and the water and oil repellency of the obtained film can be achieved at a high level. 【0022】 R 1 , R 2 , R 3 , R 4 are each a linear, branched or cyclic monovalent hydrocarbon group having 10 to 40 carbon atoms. R 1 , R 2 , R 3 , R 4 are more preferably monovalent hydrocarbon groups having 10 to 30 carbon atoms, and particularly preferably monovalent hydrocarbon groups having 12 to 30 carbon atoms. When the number of carbon atoms is within the above range, the compatibility of the water and oil repellent composition containing the polymer and the solvent and the water and oil repellency of the obtained film can be achieved at a high level. 【0023】 Also, R 1 , R 2 , R 3 , R 4The hydrocarbon group may be linear, branched, or cyclic, but a linear configuration is particularly preferred because it further enhances the packing properties of the hydrocarbon chain. Examples of monovalent linear hydrocarbon groups having 10 to 40 carbon atoms include n-decyl group, n-undecyl group, n-dodecyl group, n-tetradecyl group, n-pentadecyl group, n-hexadecyl group, n-heptadecyl group, n-octadecyl group, n-docosyl group, and n-triacontyl group. 【0024】 Also, R 1 , R 2 , R 3 , R 4 For example, R 1 and R 2 These are the same thing, R 3 and R 4 It is especially preferable that they are the same. 1 and R 2 , R 3 and R 4 If these elements are identical, the increased structural symmetry further enhances the packing properties of the hydrocarbon chains, allowing for even greater water and oil repellency. 【0025】 m is an integer from 0 to 10. It is preferable that m = 0 because the absence of alkylene groups reduces molecular mobility and improves packing properties, thereby improving water and oil repellency. It is also preferable that m = an integer from 0 to 2 in order to achieve both improved packing properties and compatibility when used in a water and oil repellent composition containing the polymer and solvent. Furthermore, it is preferable that m = an integer from 2 to 10, and particularly preferable that m = an integer from 5 to 10, in order to improve compatibility when used in a water and oil repellent composition containing the polymer and solvent. 【0026】 Specifically, the following can be given as examples of X.

When Y has the structure described above, compatibility is particularly good when a water-repellent and oil-repellent composition containing the polymer and solvent is formed. 【0029】 In formula (1) above, Z is a single bond or a divalent hydrocarbon group having 1 to 20 carbon atoms that may contain one or more atoms selected from oxygen, sulfur, nitrogen, and silicon atoms, preferably a single bond or a divalent hydrocarbon group having 1 to 20 carbon atoms that may contain oxygen and / or nitrogen atoms.

(In the formula, * represents a bond that combines with Z in general formula (1), and R' represents a hydrogen atom or a monovalent hydrocarbon group having 1 to 8 carbon atoms.) 【0033】 Here, R' is a hydrogen atom or a monovalent hydrocarbon group having 1 to 8 carbon atoms. Examples of monovalent hydrocarbon groups having 1 to 8 carbon atoms include alkyl groups such as methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert-butyl, pentyl, neopentyl, hexyl, cyclohexyl, and octyl groups; alkenyl groups such as vinyl, allyl, and propenyl groups; aryl groups such as phenyl, tolyl, xylyl, and naphthyl groups; and aralkyl groups such as benzyl, phenylethyl, and phenylpropyl groups. R' is more preferably a hydrogen atom or a methyl group. 【0034】 Specifically, the following are preferred as such V. (In the formula, * represents a bond that combines with Z in general formula (1).) 【0035】When the hydrocarbon-terminal group-containing monomer compound (α) is represented by the above formula (1), several polymers can be obtained by changing the combination of X, Y, Z, and V in the formula. 【0036】 The hydrocarbon-terminated monomer compound (α) is more preferably a hydrocarbon-terminated acrylic compound (α') represented by the following general formula (2).

When the number of carbon atoms is within the above range, it is possible to achieve a high level of compatibility when a water-repellent and oil-repellent composition containing the polymer and solvent is formed, as well as a high level of water-repellent and oil-repellent properties of the resulting film. 【0039】 Also, R 5 The hydrocarbon group may be linear, branched, or cyclic, but a linear configuration is particularly preferred because it further enhances the packing properties of the hydrocarbon chain.

The measurement conditions are as follows: Starting temperature: -150°C, ending temperature: 200°C, heating / cooling rate: 10°C / min, ambient gas: nitrogen (flow rate: 50 mL / min). 【0053】 [Method for preparing hydrocarbon-terminated monomer compounds (α)] When the hydrocarbon-terminated monomer compound (α) represented by the above general formula (1) of the present invention is in particular a hydrocarbon-terminated acrylic compound (α') or hydrocarbon-terminated acrylic compound (α'') represented by the above general formula (2) or the above general formula (3), the following methods can be used to prepare the compound. 【0054】 By mixing an alcohol compound or amine compound having a branched structure in which two monovalent hydrocarbon groups having 10 to 40 carbon atoms are bonded to the same atom with an isocyanate compound containing a (meth)acrylic group and carrying out an addition reaction, a hydrocarbon-terminal group-containing acrylic compound (α') or a hydrocarbon-terminal group-containing acrylic compound (α'') can be produced. 【0055】 Here, suitable examples of alcohol compounds having a branched structure in which two monovalent hydrocarbon groups having 10 to 40 carbon atoms are bonded to the same atom include those listed below. 【0056】 Alcohol compounds having a branched structure in which two monovalent hydrocarbon groups having 10 to 40 carbon atoms are bonded to the same atom can be produced by hydride reduction of ketone compounds having a branched structure in which two monovalent hydrocarbon groups having 10 to 40 carbon atoms are bonded to the same atom. 【0057】 Examples of ketone compounds having a branched structure in which two monovalent hydrocarbon groups with 10 to 40 carbon atoms are bonded to the same atom include those listed below. 【0058】 In hydride reduction, sodium borohydride and lithium aluminum hydride are preferred as reducing agents. It is preferable to charge equimolar or more of these reducing agents to a ketone compound having a branched structure in which two monovalent hydrocarbon groups with 10 to 40 carbon atoms are bonded to the same atom and react to allow all of the ketone to react. Specifically, it is desirable to use 1 mol to 5 mol of reducing agent per 1 mol of ketone compound having a branched structure in which two monovalent hydrocarbon groups with 10 to 40 carbon atoms are bonded to the same atom, and particularly preferably 1 mol to 3 mol. 【0059】These reactions may be carried out after dilution with a suitable solvent as needed. Such solvents are not particularly limited as long as they do not react with the reducing agent and are ketone compounds having a branched structure in which two monovalent hydrocarbon groups having 10 to 40 carbon atoms are bonded to the same atom. Specifically, examples include hydrocarbon solvents (petroleum benzine, toluene, xylene, hexane, cyclohexane, methylcyclohexane, ethylcyclohexane, heptane, octane (n-octane, isooctane, etc.), nonane (n-nonane, isononane, etc.)), ketone solvents (acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclopentanone, cyclohexanone, etc.), ether solvents (tetrahydrofuran (THF), dipropyl ether, dibutyl ether, methylcyclopentyl ether, methyl t-butyl ether, ethylene glycol dimethyl ether, diethylene glycol dimethyl ether, triethylene glycol dimethyl ether, propylene glycol dimethyl ether, etc.), and alcohol solvents (propylene glycol monomethyl ether, butanol, isopropanol, methanol, etc.). The amount of solvent used is not particularly limited, but it is preferably 20 times or less the total mass of the reactants, and particularly preferably 15 times or less. If too much solvent is used, the reaction rate may decrease significantly. As a lower limit for when solvent is used, it is preferable to use 0.5 times or more the total mass of the reactants. 【0060】 The above reaction can be carried out at a temperature of -100 to 100°C, preferably -50 to 80°C, for 5 minutes to 70 hours, preferably 30 minutes to 48 hours. 【0061】 After the reaction is complete, unreacted reducing agents and reaction solvents can be removed by distillation, adsorption, filtration, washing, etc., to obtain an alcohol compound having a branched structure in which two monovalent hydrocarbon groups having 10 to 40 carbon atoms are bonded to the same atom. 【0062】 Furthermore, the following are examples of suitable amine compounds having a branched structure in which two monovalent hydrocarbon groups having 10 to 40 carbon atoms are bonded to the same atom. 【0063】 Here, the following are examples of isocyanate compounds containing a (meth)acrylic group that are suitable: O=C=N-CH2CH2-O-C(=O)-CH=CH2 O=C=N-CH2CH2-O-C(=O)-C(CH3)=CH2 O=C=N-CH2CH2-O-CH2CH2-O-C(=O)-C(CH3)=CH2 【0064】 It is preferable to charge these isocyanate compounds containing (meth)acrylic groups in an equimolar or greater amount relative to the total amount of active hydrogen in the alcohol compound or amine compound having a branched structure in which two monovalent hydrocarbon groups of 10 to 40 carbon atoms are bonded to the same atom, and to react so that all of the active hydrogen is reacted. Specifically, it is desirable to use 1 mol to 2 mol of the isocyanate compound containing (meth)acrylic groups per 1 mol of the alcohol compound or amine compound having a branched structure in which two monovalent hydrocarbon groups of 10 to 40 carbon atoms are bonded to the same atom, and particularly preferably 1 mol to 1.4 mol. If there is too much isocyanate compound containing (meth)acrylic groups, it becomes difficult to remove the remaining isocyanate compound containing (meth)acrylic groups after the reaction. 【0065】These reactions may be carried out after dilution with a suitable solvent as needed. Such solvents are not particularly limited as long as they do not react with the isocyanate group of an isocyanate compound containing a branched structure in which two monovalent hydrocarbon groups having 10 to 40 carbon atoms are bonded to the same atom, such as a hydroxyl group, an amino group, or a (meth)acrylic group. Specifically, these include hydrocarbon solvents (petroleum benzine, toluene, xylene, hexane, cyclohexane, methylcyclohexane, ethylcyclohexane, heptane, octane (n-octane, isooctane, etc.), nonane (n-nonane, isononane, etc.)), ketone solvents (acetone, methyl ethyl ketone, methyl isobutyl ketone, cetone, methyl ethyl ke Examples of solvents include chloropentanone, cyclohexanone, etc.), ether-based solvents (tetrahydrofuran (THF), dipropyl ether, dibutyl ether, methylcyclopentyl ether, methyl t-butyl ether, ethylene glycol dimethyl ether, diethylene glycol dimethyl ether, triethylene glycol dimethyl ether, propylene glycol dimethyl ether, etc.), alcohol-based solvents (propylene glycol monomethyl ether, butanol, isopropanol, etc.), and ester-based solvents (ethyl acetate, propyl acetate, butyl acetate, pentyl acetate, propylene glycol monomethyl ether acetate, etc.). These solvents may be removed after the reaction by known methods such as reduced-pressure distillation, or they may be used as a diluted solution as is, depending on the intended use. The amount of solvent used is not particularly limited, but it is preferably 20 times or less the total mass of the reactants, and particularly preferably 15 times or less. If too much solvent is used, the reaction rate may decrease significantly. As a lower limit for when a solvent is used, it is preferably 1 time or more the total mass of the reactants. 【0066】Furthermore, polymerization inhibitors may be added during the reaction as needed. There are no particular restrictions on the polymerization inhibitor, but those commonly used as polymerization inhibitors for acrylic compounds can be used. Specifically, examples include hydroquinone, hydroquinone monomethyl ether, 4-tert-butylcatechol, and dibutylhydroxytoluene. The amount of polymerization inhibitor used should be determined based on the reaction conditions, the purification conditions after the reaction, and the final usage conditions, and is not particularly limited, but it should be 0.0001 to 5% by mass, particularly 0.001 to 1% by mass, relative to the total mass of the reaction components. 【0067】 Furthermore, an appropriate catalyst may be added to the reaction as needed. Examples of catalysts include alkyl tin ester compounds such as dibutyltin diacetate, dibutyltin dilaurate, dibutyltin dioctoate, dioctyltin diacetate, dioctyltin dilaurate, dioctyltin dioctate, and stannous dioctanoate; titanate esters or titanium chelate compounds such as tetraisopropoxytitanium, tetra-n-butoxytitanium, tetrakis(2-ethylhexoxy)titanium [also known as tetrakis(2-ethylhexyl) orthotitanium], dipropoxybis(acetylacetona)titanium, and titanium isopropoxyoctylene glycol; zirconium tetraacetylacetonate, zirconium triputoxymonoacetylacetonate, zirconium monobutoxyacetylacetonate bis(ethylacetoacetate), zirconium dibutoxybis(ethylacetoacetate), zirconium tetraacetylacetonate, and zirconium chelate compounds. These catalysts are not limited to one type, but can be used as a mixture of two or more types. The reaction rate can be increased by adding these catalysts in an amount of 0.01 to 2% by mass, more preferably 0.05 to 1% by mass, relative to the total mass of the reactants. 【0068】 The above reaction is carried out at a temperature of 0 to 120°C, preferably 10 to 70°C, for 1 minute to 500 hours, preferably 10 minutes to 48 hours. If the reaction temperature is too low, the reaction rate may be too slow, and if the reaction temperature is too high, polymerization of (meth)acrylic groups may occur as a side reaction. 【0069】 After the reaction is complete, unreacted isocyanate compounds and reaction solvents can be removed by distillation, adsorption, filtration, washing, etc., to obtain hydrocarbon-terminated acrylic compounds (α') or hydrocarbon-terminated acrylic compounds (α''). 【0070】 Furthermore, when stopping the reaction, alcohol compounds such as methanol or ethanol may be added to the system to form urethane bonds with the unreacted isocyanate compound. The resulting urethane (meth)acrylates can be removed in the same way as the unreacted isocyanate compound, but they can also be used while remaining in the mixture. 【0071】 [Method for preparing hydrocarbon-terminated monomer compound (α) (2)] When the hydrocarbon-terminated monomer compound (α) represented by the above general formula (1) of the present invention is in particular a type other than the hydrocarbon-terminated acrylic compound (α') or hydrocarbon-terminated acrylic compound (α'') represented by the above general formula (2) or (3), the following methods can be used to prepare the compound. 【0072】 For example, an ester can be formed and a copolymer obtained by reacting an alcohol compound or amine compound having a branched structure in which two monovalent hydrocarbon groups with 10 to 40 carbon atoms are bonded to the same atom with a (meth)acrylate halide. 【0073】 Here, examples of alcohol compounds or amine compounds having a branched structure in which two monovalent hydrocarbon groups having 10 to 40 carbon atoms are bonded to the same atom include those similar to those described above. 【0074】 As the (meth)acrylate halide, acrylate chloride and methacrylate chloride are particularly preferred. 【0075】These (meth)acrylic acid halides are preferably charged in equimolar or greater amounts to an alcohol compound or amine compound having a branched structure in which two monovalent hydrocarbon groups having 10 to 40 carbon atoms bonded to the same atom, and reacted to completely remove the alcohol or amine. Specifically, it is desirable to use 1 mol to 2 mol of (meth)acrylic acid halide per 1 mol of the alcohol compound or amine compound having a branched structure in which two monovalent hydrocarbon groups having 10 to 40 carbon atoms bonded to the same atom, and particularly preferably 1 mol to 1.8 mol. 【0076】 An acid acceptor is added to the ester formation reaction. Examples of suitable acid acceptors include triethylamine, pyridine, and urea. The amount of acid acceptor used should ideally be 0.9 to 3 times the number of moles of (meth)acrylate halide added. Too little acid acceptor will result in a large amount of untrapped acid remaining, while too much will make it difficult to remove the excess acid acceptor. 【0077】 These reactions may be carried out after dilution with a suitable solvent as needed. Such solvents are not particularly limited, as long as they do not react with the hydroxyl or amino groups of alcohol compounds or amine compounds having a branched structure in which two monovalent hydrocarbon groups with 10 to 40 carbon atoms are bonded to the same atom, or with the halogen atoms of (meth)acrylate halides. Specifically, examples include hydrocarbon solvents such as toluene, xylene, and isooctane; ether solvents such as tetrahydrofuran (THF), diisopropyl ether, and dibutyl ether; and ketone solvents such as acetone, methyl ethyl ketone, methyl butyl ketone, methyl isobutyl ketone, and cyclohexanone. This solvent may be removed after the reaction by known methods such as vacuum distillation, or it may be used as a diluted solution as is, depending on the intended application. The amount of solvent used is not particularly limited, but it is preferably 20 times or less the total mass of the reactants, and particularly preferably 15 times or less. Using too much solvent may significantly reduce the reaction rate. A preferred lower limit for the amount of solvent used is 0.5 times or more the total mass of the reactants. 【0078】Furthermore, polymerization inhibitors may be added during the reaction as needed. There are no particular restrictions on the polymerization inhibitor, but those commonly used as polymerization inhibitors for acrylic compounds can be used. Specifically, examples include hydroquinone, hydroquinone monomethyl ether, 4-tert-butylcatechol, and dibutylhydroxytoluene. The amount of polymerization inhibitor used should be determined based on the reaction conditions, the purification conditions after the reaction, and the final usage conditions, and is not particularly limited, but it should be 0.0001 to 5% by mass, and especially 0.001 to 1% by mass, relative to the total mass of the reaction components. 【0079】 The ester formation reaction involves mixing and stirring an alcohol compound or amine compound having a branched structure in which two monovalent hydrocarbon groups having 10 to 40 carbon atoms are bonded to the same atom, an acid acceptor, and optionally a solvent and polymerization inhibitor at 0 to 100°C for 1 minute to 48 hours, followed by mixing in (meth)acrylate halide. 【0080】 After mixing with (meth)acrylic acid halide, the temperature of the reaction mixture is maintained at 0 to 100°C, and stirring is continued for 30 minutes to 10 hours. After the reaction is complete, unreacted (meth)acrylic acid halide, salts and reaction solvents generated by the reaction are removed by distillation, adsorption, filtration, washing, etc., to obtain hydrocarbon-end group-containing monomer compounds other than hydrocarbon-end group-containing acrylic compounds (α') or hydrocarbon-end group-containing acrylic compounds (α''). 【0081】 Alternatively, when stopping the reaction, an alcohol compound such as methanol or ethanol may be added to the system to esterify the unreacted (meth)acrylic acid halide. The resulting (meth)acrylic acid esters can be removed by the same method as for removing the unreacted (meth)acrylic acid halide, but they can also be used as is. 【0082】 The hydrocarbon-terminal group-containing monomer compounds represented by general formula (1) obtained by reactions such as those described above can be used as single substances after purification and isolation operations such as concentration, column purification, distillation, and extraction. Alternatively, the reaction solution can be used as a mixture containing the hydrocarbon-terminal group-containing monomer compound represented by general formula (1), or it can be used after further dilution with an organic solvent or the like. 【0083】 [Method for producing polymers] The polymer of the present invention has a hydrocarbon terminal group-containing monomer compound (α) represented by the above general formula (1) as its monomer component (having repeating units formed from the hydrocarbon terminal group-containing monomer compound (α) represented by the above general formula (1)), and the polymer can be produced by a radical polymerization reaction of the hydrocarbon terminal group-containing monomer compound (α) represented by the above general formula (1). 【0084】 In radical polymerization reactions, solvents can be used to produce polymers. The solvent used in the production of polymers can be any solvent that can dissolve the monomer components and does not react with them, without any particular restrictions. Specifically, examples include hydrocarbon solvents (petroleum benzine, toluene, xylene, hexane, cyclohexane, methylcyclohexane, ethylcyclohexane, heptane, octane (n-octane, isooctane, etc.), nonane (n-nonane, isononane, etc.)), ketone solvents (acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclopentanone, cyclohexanone, etc.), ether solvents (tetrahydrofuran (THF), dipropyl ether, dibutyl ether, methylcyclopentyl ether, methyl t-butyl ether, ethylene glycol dimethyl ether, diethylene glycol dimethyl ether, triethylene glycol dimethyl ether, propylene glycol dimethyl ether, etc.), alcohol solvents (propylene glycol monomethyl ether, butanol, isopropanol, etc.), and ester solvents (ethyl acetate, propyl acetate, butyl acetate, pentyl acetate, propylene glycol monomethyl ether acetate, etc.). This solvent may be removed after the reaction by known methods such as vacuum distillation, or it may be used as a diluted solution as is, depending on the intended use. The amount of solvent used is not particularly limited, but it is preferably 100 times or less of the total amount of monomers, and particularly preferably 50 times or less. If too much solvent is used, the polymerization reaction may not be completed. There is no lower limit for the amount of solvent used, and bulk polymerization without solvent is also possible. 【0085】In the radical polymerization reaction described above, polymerization initiators can be used to produce polymers. Examples of radical polymerization initiators that can be used in the production of polymers include cumene hydroperoxide, succinate peroxide, di-t-butyl peroxide, diisobutyryl peroxide, diisobutyl peroxydicarbonate, dicumyl peroxide, cyclohexanone peroxide, benzoyl peroxide, methyl ethyl ketone peroxide, lauroyl peroxide, 2,5-dimethyl-2,5-di(t-butylperoxy)-hexyne-3, 2,5-dimethyl-2,5-di(t-butylperoxy)hexane, 2,5-dimethylhexane-2,5-dihydroperoxide, t-butyl-α-cumyl peroxide, t-butyl peroxyacetate, and t-butyl peroxy-2-ethylhexanoyl Examples include azo compounds such as t-butylperoxyisobutyrate, t-butylperoxyisopropyl carbonate, t-butyl hydroperoxide, α,α'-bis(t-butylperoxy)-p-diisopropylbenzene, 2,2'-azobis(isobutyrate)dimethyl, dimethyl=2,2'-azobisisobutyrate, 2,2'-azobis(2-methylamidooxime) dihydrochloride, 2,2'-azobis(2-methylbutyronitrile), 2,2'-azobis(isobutylamidine) dihydrochloride, 2,2'-azobis[2-(2-imidazolin-2-yl)propane] and its disulfate, 2,2'-azobisisobutyronitrile, organic peroxides, potassium persulfate, sodium persulfate, and ammonium persulfate. These radical polymerization initiators may be used individually or in combination of two or more. The amount of radical polymerization initiator used is not particularly limited, but it is preferably 0.0005 to 20 parts by mass, and more preferably 0.001 to 10 parts by mass, per 100 parts by mass of the total amount of monomer. 【0086】In the radical polymerization reaction described above, a chain transfer agent may be used to produce the polymer. The molecular weight of the polymer can be changed depending on the amount of chain transfer agent used. Examples of chain transfer agents include mercaptan group-containing compounds such as dodecyl mercaptan, thioglycol, and thioglycerol (especially alkyl mercaptans (e.g., having 1 to 40 carbon atoms)), and inorganic salts such as sodium hypophosphite and sodium bisulfite. The amount of chain transfer agent used is not particularly limited, but it is preferably 0.0005 to 20 parts by mass, and particularly preferably 0.001 to 10 parts by mass, per 100 parts by mass of the total amount of monomer. 【0087】 In the polymerization method using the above-mentioned solvent and radical polymerization initiator, the polymerization conditions for the polymer are preferably 30 to 120°C, particularly 40 to 100°C, under an inert gas atmosphere for 1 to 48 hours, and especially 3 to 36 hours. 【0088】 After the polymer reaction is complete, unreacted monomers, polymerization initiators, residues derived from the polymerization initiators generated by the reaction, and reaction solvents may be removed by distillation, adsorption, filtration, reprecipitation, centrifugation, washing, etc. Alternatively, the polymerization reaction solution may be used as is as a water-repellent and oil-repellent composition. 【0089】 In this way, a polymer can be produced by a radical polymerization reaction of the hydrocarbon terminal group-containing monomer compound (α) represented by the above general formula (1). 【0090】[Copolymer] The polymer of the present invention may be a homopolymer having only the hydrocarbon-end group-containing monomer compound (α) represented by general formula (1) as a monomer component (having only repeating units formed from the hydrocarbon-end group-containing monomer compound (α) represented by general formula (1)), or it may be a copolymer having the hydrocarbon-end group-containing monomer compound (α) represented by general formula (1) and monomer compounds other than the hydrocarbon-end group-containing monomer compound (α) represented by general formula (1) as monomer components (having repeating units formed from the hydrocarbon-end group-containing monomer compound (α) represented by general formula (1) and repeating units formed from monomer compounds other than the hydrocarbon-end group-containing monomer compound (α) represented by general formula (1)). Examples of monomer components other than the hydrocarbon-end group-containing monomer compound (α) represented by general formula (1) include a monomer compound (β) having a hydrophilic group and an acrylic compound (γ) represented by general formula (4), which will be described later. In the present invention, the copolymers described above are included in polymers. Because the hydrocarbon chains of the repeating units formed from the hydrocarbon terminal group-containing monomer compound (α) represented by general formula (1) segregate on the surface of the coating, the resulting coating exhibits excellent water-repellent and oil-repellent properties even when used as a copolymer. 【0091】 When the total repeating units in the polymer of the present invention are set to 100 mol%, the repeating units formed from the hydrocarbon terminal group-containing monomer compound (α) represented by general formula (1) are preferably 1 to 100 mol%, and more preferably 5 to 100 mol%. If the mol% of the repeating units formed from the hydrocarbon terminal group-containing monomer compound (α) represented by general formula (1) is less than the above lower limit, the water-repellent and oil-repellent properties of the resulting film may be insufficient. 【0092】 The content of repeating units formed from hydrocarbon-terminated monomer compounds (α) represented by general formula (1), and the content of repeating units formed from monomer compounds other than hydrocarbon-terminated monomer compounds (α) represented by general formula (1) are as follows: 1In 1H-NMR measurements, this can be calculated from the ratio of the integral values ​​of the signals derived from each monomer compound. It can also be calculated from the amount of these monomer compounds used during polymer production. For example, when a copolymer is synthesized by copolymerizing a hydrocarbon-end group-containing monomer compound (α) represented by general formula (1) with monomer compounds other than the hydrocarbon-end group-containing monomer compound (α) represented by general formula (1), the amount of hydrocarbon-end group-containing monomer compound (α) represented by general formula (1) used can be considered as the content of repeating units formed from the hydrocarbon-end group-containing monomer compound (α) represented by general formula (1), and the amount of monomer compounds other than the hydrocarbon-end group-containing monomer compound (α) represented by general formula (1) used can be considered as the content of repeating units formed from monomer compounds other than the hydrocarbon-end group-containing monomer compound (α) represented by general formula (1). 【0093】 [Hydrophilic group-containing monomer compound (β)] The polymer of the present invention may be a copolymer comprising a hydrocarbon-terminated group-containing monomer compound (α) represented by general formula (1), as well as a monomer compound (β) having a hydrophilic group as a monomer component. Due to the presence of a highly polar hydrophilic group, a film formed by a water-repellent and oil-repellent composition containing this copolymer exhibits good adhesion to the substrate. 【0094】 The monomer compound (β) having a hydrophilic group is one that has both a hydrophilic group and a polymerizable group. Preferred hydrophilic groups in the monomer compound (β) are hydroxyl groups, amino groups, carboxylic acid groups, sulfonic acid groups, hydrolyzable silyl groups, oxyalkylene groups, anionic groups, cationic groups, and amphoteric groups. When the hydrophilic group is one of those listed above, the film formed by the water-repellent and oil-repellent composition containing a copolymer with this monomer compound (β) having a hydrophilic group as a monomer component exhibits even better adhesion to the substrate. 【0095】Polymerizable groups in the monomer compound (β) having a hydrophilic group include (meth)acryloyl group, vinyl group, allyl group, isopropenyl group, styryl group, vinyloxy group, vinyloxycarbonyl group, vinylcarbonyl group, N-vinylamino group, etc., with (meth)acryloyl group being particularly preferred. 【0096】Specific examples of monomer compounds (β) having hydrophilic groups include: hydroxyl group-containing monomers; hydroxyalkylene (meth)acrylate, 4-hydroxybutyl acrylate, 2-hydroxyethyl vinyl ether, 4-hydroxybutyl vinyl ether, diethylene glycol monovinyl ether, hydroxyethyl allyl ether, hydroxyethyl carboxylate vinyl ester, p-hydroxystyrene, dihydroxystyrene, etc.; amino group-containing monomers; dimethylaminoethyl methacrylate, dimethylaminoethyl acrylate (also known as 2-(dimethylamino)ethyl acrylate), diethylaminoethyl methacrylate, diethylaminoethyl acrylate, etc.; carboxylic acid group-containing monomers; vinyl benzoic acid, vinyl acetic acid, maleic anhydride, maleic acid, maleic acid ester, fumaric acid ester, crotonic acid, itaconic acid, fumaric acid, citraconic anhydride, mono-2-(methacryloyloxy)ethyl phthalate, mono-2-(methacryloyloxy) monomers containing sulfonic acid groups, such as tyl succinate and mono-2-(acryloyloxy)ethyl succinate; monomers containing hydrolyzable silyl groups, such as styrene sulfonic acid, 4-(methacryloyloxy)butyl sulfonic acid, methallyl sulfonic acid, vinyl sulfonic acid, and 2-acrylamido-2-methylpropanesulfonic acid; monomers containing oxyalkylene groups, such as vinyltrimethoxysilane, vinyltriethoxysilane, vinyldimethoxymethylsilane, allyltrimethoxysilane, allyltriethoxysilane, allyldimethoxymethylsilane, vinyloxypropyltrimethylsiloxysilane, vinyloxyethoxypropyltrimethylsiloxysilane, 3-trimethoxysilylpropyl acrylate, and 3-trimethoxysilylpropyl methacrylate; monomers containing anionic groups, such as methoxypolyethylene glycol (meth)acrylate, ethoxypolyethylene glycol (meth)acrylate, and butoxypolyethylene glycol (meth)acrylate;Vinylbenzoic acid, vinyl acetic acid, maleic anhydride, maleic acid, maleic acid esters, fumaric acid esters, crotonic acid, itaconic acid, fumaric acid, citraconic anhydride, mono-2-(methacryloyloxy)ethyl phthalate, mono-2-(methacryloyloxy)ethyl succinate, mono-2-(acryloyloxy)ethyl succinate, etc., neutralized products, styrene sulfonic acid, 4-(methacryloyloxy)butyl sulfonic acid, methallyl sulfonic acid, vinyl sulfonic acid, 2-acrylamido-2-methylpropanesulfonic acid, etc., cationic group-containing monomers; dimethylaminopropyl acrylamide methyl chloride quaternary salt, [(2-meth Examples include amphoteric group-containing monomers such as [cryloyloxy)ethyl]trimethylammonium chloride and [(2-acryloyloxy)ethyl]trimethylammonium chloride; monomers containing quaternary ammonium groups and carboxyl groups such as N-methacryloyloxyethyl-N,N-dimethylammonium-α-N-methylcarboxybetaine; monomers containing quaternary ammonium groups and phosphate groups such as 2-methacryloyloxyethyl phosphorylcholine; and monomers containing quaternary ammonium groups and sulfonic acid groups such as methacryloyloxyethyl-N,N-dimethyl3-sulfopropylammonium hydroxide. 【0097】 In the polymer of the present invention, when a monomer compound having a hydrophilic group (β) is used as a monomer component in addition to the hydrocarbon terminal group-containing monomer compound (α) represented by general formula (1), it is preferable that the repeating units formed from the monomer compound having a hydrophilic group (β) constitute 0.1 to 99 mol% of the total repeating units in the polymer of the present invention, and more preferably 0.5 to 80 mol%. 【0098】 [Acrylic compound (γ)] Furthermore, the polymer of the present invention, in addition to the hydrocarbon terminal group-containing monomer compound (α) represented by general formula (1), also contains the following general formula (4) R 7 -Y 1 -C(=O)-C(-X 1 )=CH2 (4) (wherein, R 7This is a monovalent hydrocarbon group having 1 to 40 carbon atoms, but does not include a monovalent hydrocarbon group having a branched structure in which two monovalent hydrocarbon groups having 10 or more carbon atoms are bonded to the same atom, Y 1 is -O- or -NH-, X 1 The monomer component may be an acrylic compound (γ) represented by formula (4), which is a hydrogen atom, a monovalent hydrocarbon group having 1 to 8 carbon atoms, or a halogen atom. Generally, the properties of a polymer coating are affected by the glass transition temperature of the polymer. By adjusting the amount of monomer component of the acrylic compound (γ) (the content of repeating units formed from the acrylic compound (γ)), ​​the glass transition temperature of the polymer can be controlled, and a polymer with appropriate properties can be obtained depending on the application and type of substrate. Note that the acrylic compound (γ) represented by formula (4) does not contain the hydrocarbon terminal group-containing monomer compound (α) represented by general formula (1). 【0099】 Here, in equation (4) above, R 7 This refers to monovalent hydrocarbon groups having 1 to 40 carbon atoms, specifically including alkyl groups such as methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert-butyl, pentyl, neopentyl, hexyl, cyclohexyl, octyl, decyl, dodecyl, tetradecyl, hexadecyl, and octadecyl; alkenyl groups such as vinyl, allyl, and propenyl; aryl groups such as phenyl, tolyl, xylyl, and naphthyl; and aralkyl groups such as benzyl, phenylethyl, and phenylpropyl.

Examples of monovalent hydrocarbon groups having 1 to 8 carbon atoms include those similar to the monovalent hydrocarbon group R' described above. Among these, hydrogen atoms and methyl groups are preferred. 【0101】Specific examples of the acrylic compound (γ) represented by the above formula (4) include linear and branched alkyl (meth)acrylates such as methyl (meth)acrylate, ethyl (meth)acrylate (also known as ethyl (meth)acrylate), propyl (meth)acrylate, butyl (meth)acrylate, pentyl (meth)acrylate, hexyl (meth)acrylate, heptyl (meth)acrylate, octyl (meth)acrylate, decyl (meth)acrylate, dodecyl (meth)acrylate, tetradecyl (meth)acrylate, hexadecyl (meth)acrylate, octadecyl (meth)acrylate, and behenyl (meth)acrylate, as well as cyclic alkyl (meth)acrylates such as cyclohexyl (meth)acrylate, benzyl (meth)acrylate, phenoxyethyl (meth)acrylate, and isobornyl (meth)acrylate. 【0102】 In the polymer of the present invention, when an acrylic compound (γ) represented by general formula (4) is used as a monomer component in addition to a hydrocarbon terminal group-containing monomer compound (α) represented by general formula (1), it is preferable that the repeating units formed from the acrylic compound (γ) represented by general formula (4) constitute 0.1 to 99 mol% of the total repeating units in the polymer of the present invention, and more preferably 0.5 to 80 mol%. 【0103】 [Monomer Compound (δ)] The polymer of the present invention may be a copolymer in which, in addition to the hydrocarbon-terminated monomer compound (α) represented by general formula (1), a monomer compound (δ) other than the above-mentioned monomer compounds (hydrocarbon-terminated monomer compound (α) represented by general formula (1), a monomer compound having a hydrophilic group (β), and an acrylic compound (γ) represented by general formula (4)) is used as a monomer component. 【0104】Specific examples of monomer compounds (δ) other than the monomer compounds mentioned above (monomer compounds containing hydrocarbon terminal groups represented by general formula (1) (α), monomer compounds having hydrophilic groups (β), and acrylic compounds represented by general formula (4) (γ)) include (meth)acrylic acid esters; monocarboxylic acids such as (meth)acrylic acid; dicarboxylic acids such as itaconic acid, maleic acid, and succinic acid, their half-esters (monoesters), their diesters, and their acid anhydrides; styrenes such as styrene and α-methylstyrene; vinyl esters such as vinyl acetate and vinyl propionate. 【0105】 In the polymer of the present invention, when a monomer compound other than the above-mentioned monomer compound (δ) is used as a monomer component in addition to the hydrocarbon terminal group-containing monomer compound (α) represented by general formula (1), it is preferable that the repeating units formed from the monomer compound (δ) constitute 0.1 to 99 mol% of the total repeating units in the polymer of the present invention, and more preferably 0.5 to 80 mol%. 【0106】 [Method for producing copolymers] When the polymer of the present invention is a copolymer, it may be a random copolymer or a block copolymer. 【0107】 The block copolymer may be an i-ii block copolymer having one block segment (i) and one other segment (ii), an i-iii-i block copolymer having two block segments (i) and one other segment (ii), or an ii-i-ii block copolymer having one block segment (i) and two other segments (ii). The block copolymer may also have an additional segment (iii) other than the block segment (i) and the other segments (ii). The block copolymer may be, for example, an i-ii-iii block copolymer or an ii-i-iiii block copolymer. The block copolymer can be produced by living polymerization, for example, living radical polymerization. 【0108】Living radical polymerization is based on the application of heat, light, metal catalysts, etc., to establish a rapid equilibrium between a small amount of growing radicals (free radicals) and a large amount of dormant species in the growth reaction. Various forms of living radical polymerization have been proposed using dormant chains. 【0109】 For example, methods such as the ATRP method (atomic transfer radical polymerization), which mainly uses alkyl halides as dormants; the RAFT method, which mainly uses thioesters; and the NMP method, which mainly uses alkoxyamines, have been proposed. 【0110】 The ATRP (atomic transfer radical polymerization) method is a method for polymerizing vinyl monomers using a polymerization initiator having a highly reactive carbon-halogen bond and a transition metal complex that acts as a polymerization catalyst. 【0111】 The RAFT method is a method for polymerizing vinyl monomers by adding a chain transfer agent with a high chain transfer constant, called a RAFT agent, to a conventional radical polymerization system. Thioesters can be used as RAFT agents. Examples of thioesters include, for example, 4-cyano-4-[(dodecylsulfanylthiocarbonyl)sulfanyl]pentanoic acid, 2-cyano-2-[(dodecylsulfanylthiocarbonyl)sulfanyl]propane, S,S-dibenzyltrithiotansanate, 4-cyano-4-[(dodecylsulfanylthiocarbonyl)sulfanyl]methyl pentanoate, trithiotansan=bis[4-(allyloxycarbonyl)benzyl], trithiotansan=bis[4-(2,3-dihydroxypropoxycarbonyl)benzyl], trithiotansan=bis{4-[ethyl-(2-acetyloxyethyl)carbamoyl]benzyl}, trithiotansan=bis{4-[ethyl-(2-hydroxyethyl)carbamoyl]benzyl}, trithiotansan=bis[4-(2-hydroxyethoxycarbonyl)benzyl], and others. The amount of thioester used is preferably 0.0001 to 0.5 moles per 1 mole of total monomers, and particularly preferably 0.001 to 0.1 moles. 【0112】The NMP method involves thermally cleaving alkoxyamines to generate stable nitrooxides and polymer radicals, and then polymerizing vinyl monomers onto these polymer radicals. 【0113】 A block copolymer can be obtained by performing a first block segment formation step using the conventionally known living radical polymerization process described above, and then subjecting the mixture to a second block segment formation step. After the first block segment formation step, the polymerization reaction solution may be used as is for the next step, or the block chains may be separated and purified according to a well-known method before the second block segment formation step is performed. For example, residual monomers and solvents may be removed by distillation, reprecipitation in a suitable solvent may be performed, the precipitated polymer may be filtered or centrifuged, and the polymer may be washed and dried. 【0114】 The weight-average molecular weight of the polymer of the present invention is not particularly limited, but for example, it is preferably 20,000 or more, more preferably 20,000 to 10,000,000, even more preferably 20,000 to 5,000,000, and most preferably 20,000 to 200,000, as determined by gel permeation chromatography in terms of polystyrene. When the weight-average molecular weight is within the above range, the polymer and solvent are blended to form a water-repellent and oil-repellent composition, resulting in good compatibility. In order to make the polymer of the present invention fall within the above weight-average molecular weight range, it is effective to adjust the types and blending ratios of monomers, radical polymerization initiators, polymerization inhibitors, and solvents used in the production of the polymer. 【0115】In this invention, the weight-average molecular weight in polystyrene terms can be determined by gel permeation chromatography under the following measurement conditions.

After coating, a film made of the polymer is obtained by evaporating the solvent. 【0124】The solvent evaporation conditions are not particularly limited, but it is preferable to use a temperature of 0 to 200°C, particularly 20 to 150°C, for 1 minute to 36 hours, and especially 1 minute to 24 hours. 【0125】 Furthermore, the appropriate thickness of the film formed using the water-repellent and oil-repellent composition of the present invention varies greatly depending on the method of use, etc., and is not limited by thickness, but for example, the film thickness may be 0.005 to 100 μm.
