After simple drying at room temperature or high temperature, the processed paper may optionally be heat-treated depending on the properties of the paper. The heat treatment temperature may be 150°C or higher, 180°C or higher, or 210°C or higher, and may be 300°C or lower, 250°C or lower, or 200°C or lower, and may be particularly 80°C to 180°C. By performing heat treatment in such a temperature range, excellent oil resistance and water resistance can be obtained. The pulp substrate, which has undergone internal additive treatment, may be subjected to external additive treatment with an oil-resistant composition, and further oil-resistant compositions may be applied to the surface. 【0256】 The processing method may be an external additive treatment in which an oil-resistant composition is applied to the pulp substrate after papermaking. Size presses for external additive treatment can also be classified as follows according to the application method. One application method is the so-called pound-type two-roll size press, in which a coating liquid (sizing liquid) is supplied to the nip portion formed by passing paper between two rubber rolls, creating a coating liquid reservoir called a pound, and the sizing liquid is applied to both sides of the paper by passing the paper through this reservoir. Other application methods are the gate-roll type and the rod-metering size press, in which the sizing liquid is applied by a surface transfer type. In the pound-type two-roll size press, the sizing liquid easily penetrates into the interior of the paper, while in the surface transfer type, the sizing liquid components tend to remain on the surface of the paper. Compared to the pound-type two-roll size press, the surface transfer type allows the coating layer to remain on the surface of the paper more easily, and the coating layer formed on the surface is greater than that of the pound-type two-roll size press. In this disclosure, performance can be imparted to the paper even when the former pound-type two-roll size press is used. Paper processed in this manner can exhibit excellent oil and water resistance after simple drying at room temperature or high temperature, and optionally, depending on the properties of the paper, undergo heat treatment up to 300°C, for example, up to 200°C, and particularly within a temperature range of 80°C to 180°C. 【0257】 The paper is preferably a pulp molded product. Pulp molded products can be manufactured by a manufacturing method that includes preparing a blended pulp slurry by adding an oil-resistant composition to a slurry in which pulp is dispersed in an aqueous medium, forming a pulp molded intermediate, dewatering it, and then drying it to obtain a pulp molded product. 【0258】 To the pulp (slurry), hydrocarbon group-containing polymers and amphoteric polyacrylamide polymers, preferably hydrocarbon group-containing polymers, amphoteric polyacrylamide polymers, and anionic polyacrylamide polymers, may be added all simultaneously, two simultaneously, or all separately, preferably in this order. For example, to the pulp (slurry), a hydrocarbon group-containing polymer may be added first, followed by the addition of amphoteric polyacrylamide polymers and anionic polyacrylamide polymers simultaneously or separately, preferably in this order. Adding the hydrocarbon group-containing polymer first is preferable because it allows for efficient fixation of hydrocarbon groups to the pulp, which can lead to better effects of this disclosure. The proportion of each component in the compounded pulp slurry (overall standard) can be appropriately selected to achieve a high degree of filtration suitable for papermaking and dewatering, and according to the desired physical properties of the pulp molded product. For example, it may be as follows: • Aqueous media: 89.5–99.89% by weight, e.g., 94.5–99.69% by weight • Pulp: 0.1-5% by weight, e.g., 0.3-2.5% by weight • Hydrocarbon group-containing polymer (oil-resistant composition): 0.00001 to 1% by weight, for example, 0.0001 to 0.5% by weight • Amphoteric polyacrylamide polymer 0.00001 to 1% by weight, for example 0.0001 to 0.5% by weight • Anionic acrylamide polymer 0.00001 to 1% by weight, for example 0.0001 to 0.5% by weight, • Cationic coagulant (solid content) 0-1% by weight, e.g., 0.00005-0.5% by weight • Water-resistant agent (solid content): 0-1% by weight, for example, 0.00005-0.5% by weight. In addition, if any of the components are in the form of a dispersion or the like, the percentage of solid content of each component in the compounded pulp slurry (based on the overall standard) shall be indicated. 【0259】 From another perspective, the respective proportions of pulp and oil-resistant composition in the aqueous medium of the pulp slurry can be appropriately selected to achieve a high degree of filtration suitable for papermaking and dewatering, for example, as follows: Pulp: 0.1-5.58% by weight, especially 0.3-2.64% by weight • Oil-resistant composition (solids content): 0.001-2.79% by weight, especially 0.005-1.05% by weight 【0260】 The electrical conductivity of the blended pulp slurry should be within the ranges of 0.1–2000 μS / cm, 0.1–1000 μS / cm, 1–800 μS / cm, or 10–500 μS / cm. Within this range, high oil resistance can be achieved. The pH of the formulated pulp slurry is good between 4 and 9, better between 5 and 8, and even better between 6 and 7. Within this range, high oil resistance can be achieved. The water hardness used in the blended pulp slurry should ideally be 5000 ppm or less, 3000 ppm or less is better, 1000 ppm or less is particularly good, and 500 ppm or less is exceptionally good. Within this range, high oil resistance can be achieved. 【0261】 Next, a pulp mold intermediate is formed from the prepared pulp slurry, dehydrated, and then at least dried to obtain a pulp mold product. 【0262】 Papermaking, dehydration, and drying can be carried out according to conventionally known methods for pulp molds. 【0263】 For example, by filtering and dewatering a prepared pulp slurry using a mold of a desired shape with numerous pores (a filter may be provided if necessary), the aqueous medium can be at least partially removed from the prepared pulp slurry, and a pulp mold intermediate having a shape corresponding to the mold can be obtained. 【0264】 Drying may be carried out at a temperature that can effectively remove any remaining aqueous medium, for example, 90–250°C, particularly 100–200°C. The drying time is not particularly limited and can be selected so that the aqueous medium remaining in the pulp mold intermediate is substantially removed. The drying atmosphere is not particularly limited and can be simply the ambient atmosphere (air at normal pressure). 【0265】 During and / or thereafter, if necessary, other conventionally known processes in the pulp mold, such as press molding (including heat pressing), may be carried out. 【0266】 As described above, pulp molded products can be manufactured. Such pulp molded products contain pulp and an oil-resistant composition, and can achieve high gas barrier properties and excellent water and oil resistance. 【0267】 The proportion of pulp, oil-resistant composition, etc., contained in pulp molded products can be considered to be substantially equal to the proportion of solids of these components used as raw materials (although aqueous media and other liquid media, if present, can usually be removed by drying and press molding, solids may remain without being removed or decomposed). 【0268】 In pulp molded products, the ratio of each component (components that may remain in the pulp molded product) to the pulp (solid content) can be appropriately selected according to the desired physical properties of the pulp molded product, but for example, it may be as follows. • Hydrocarbon group-containing polymer: 0.01-10% by weight or 0.01-5% by weight, for example, 0.05-2% by weight • 0.01-10% by weight or 0.01-5% by weight of amphoteric polyacrylamide polymer, for example, 0.05-2% by weight • 0-5% by weight or 0.01-2% by weight of anionic acrylamide polymer, for example, 0.05-1% by weight 【0269】 Pulp molded products contain an oil-resistant composition (added to pulp slurry and manufactured by the pulp molding process). Therefore, after use, the entire pulp molded product can be crushed and returned to its original raw material, making it suitable for recycling. Furthermore, such pulp molded products can utilize the inherent biodegradability of pulp, thus significantly reducing, and preferably substantially eliminating, the environmental burden. In addition, such pulp molded products retain the texture of pulp on the surface, and do not develop a glossy appearance that can be impaired, such as when the surface is laminated with a plastic film. 【0270】 Such pulp molded products can be suitably used as food containers (including trays, etc.), for example, as storage containers for frozen foods and chilled foods. 【0271】 Specific examples of pulp products include paper, paper containers, pulp molded articles, food packaging materials, food containers, gypsum board base paper, coated base paper, medium-grade paper, general liners and cores, neutral pure white roll paper, neutral liners, rust-preventive liners and metal interleaving paper, kraft paper, neutral printing and writing paper, neutral coated base paper, neutral PPC paper, neutral thermal paper, neutral pressure-sensitive base paper, neutral inkjet paper, and neutral information paper. Pulp products can be used as oil-resistant or water-resistant paper. Suitable examples of pulp products include food packaging materials and food containers, and in particular, pulp molded articles for food contact applications. 【0272】 <Nonwoven fabric products / Manufacturing methods for nonwoven fabric products> The nonwoven fabric products in this disclosure include an oil-resistant composition and a nonwoven fabric substrate. The nonwoven fabric products in this disclosure may have excellent oil resistance and / or water resistance, preferably both. 【0273】 The method for manufacturing a nonwoven fabric product in this disclosure includes a step of treating a nonwoven fabric substrate with an oil-resistant composition. 【0274】 [Processing method] The oil-resistant composition of this disclosure can be applied to a nonwoven fabric substrate as a treatment agent (particularly a surface treatment agent) by conventionally known methods. The oil-resistant composition of this disclosure may be diluted by dispersing it in an organic solvent or water as needed, and then applied to the surface of the substrate by known methods such as immersion coating, spray coating, or foam coating, followed by drying. After drying, a nonwoven fabric product with the solid components of the oil-resistant composition attached is obtained. If necessary, it may also be applied together with a suitable crosslinking agent and cured. Furthermore, the oil-resistant composition of this disclosure can be used in combination with various additives such as water-repellent and / or oil-repellent agents, anti-slip agents, antistatic agents, texture modifiers, softeners, antibacterial agents, flame retardants, paint fixatives, anti-wrinkle agents, drying rate modifiers, crosslinking agents, film-forming aids, compatibilizers, antifreeze agents, viscosity modifiers, ultraviolet absorbers, antioxidants, pH adjusters, insecticides, and defoaming agents. Examples of various additives may be the same as those described in "other components" in the oil-resistant composition described above. The concentration of the hydrocarbon-containing polymer (1) in the treatment agent that comes into contact with the substrate may be changed as appropriate depending on the application, but may be 0.01 to 10% by weight, for example, 0.05 to 5% by weight. 【0275】 [Nonwoven fabric base material] Various examples of nonwoven fabric base materials can be given, but these include natural animal and plant fibers such as cotton, linen, wool, and silk; synthetic fibers such as polyamide, polyester, polyvinyl alcohol, polyacrylonitrile, polyvinyl chloride, and polypropylene; semi-synthetic fibers such as rayon and acetate; inorganic fibers such as glass fibers, carbon fibers, and asbestos fibers; or blends thereof. The nonwoven fabric base material may be a nonwoven fabric, a fabric base material in the form of clothing, or a carpet base material, or it may be a fiber, yarn, or intermediate product (e.g., sliver or roving yarn) in its pre-fabric state. 【0276】 Examples of natural fibers include cellulose fibers such as cotton, flax, and pulp, as well as chitin, chitosan, wool, and silk.

Note that nonwoven fabric products are not paper products and do not necessarily need to contain pulp as a raw material. 【0277】 Examples of synthetic fibers include polyesters such as polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, and copolymerized polyester; polyolefins such as linear low-density polyethylene, low-density polyethylene, high-density polyethylene, and polypropylene; polyamides such as nylon 6, nylon 66, nylon 610, and nylon 46; acrylic fibers such as polyacrylonitrile; and polyvinyl alcohol, polyurethane, and polyvinyl chloride. Examples of semi-synthetic fibers include acetate and triacetate. Examples of regenerated fibers include rayon, cupro, polynosic rayon, lyocell, and Tencel. Examples of inorganic fibers include glass fiber and carbon fiber. 【0278】 "Treatment" means applying the oil-resistant composition to the substrate by immersion, spraying, coating, etc. Through treatment, the polymer, which is the active ingredient of the oil-resistant composition, penetrates into the substrate and / or adheres to the surface of the substrate. 【0279】 The oil-resistant composition can be applied to a nonwoven fabric substrate (e.g., cloth) by any known method for treating the nonwoven fabric substrate with a liquid. The nonwoven fabric substrate may be immersed in the oil-resistant composition, or the solution may be applied to or sprayed onto the nonwoven fabric substrate. The treated substrate is preferably dried and cured by heating to exhibit water- and oil-repellent properties. The heating temperature may be, for example, 100°C to 200°C, 100°C to 170°C, or 100°C to 120°C. Good performance can also be obtained with low-temperature heating (e.g., 100°C to 140°C) in this disclosure. The heating time may be 5 seconds to 60 minutes in this disclosure, for example, 30 seconds to 3 minutes. 【0280】 Alternatively, the oil-resistant composition may be applied to the nonwoven fabric substrate by a cleaning method, for example, by washing or dry cleaning. 【0281】 [Pretreatment of nonwoven fabric substrate] The nonwoven fabric substrate may be pre-treated before being treated with the oil-resistant composition of this disclosure. Pre-treating the nonwoven fabric substrate can impart excellent durability to the nonwoven fabric product after treatment with the oil-resistant composition. 【0282】 Examples of pretreatments for nonwoven fabric substrates include cationization by reaction with reactive quaternary ammonium salts, anionization by sulfonation, carboxylation, phosphorylation, etc., acetylation, benzoylation, carboxymethylation, grafting, tannic acid treatment, and polymer coating after anionization. 【0283】 The method for pre-treating the nonwoven fabric substrate is not limited, but it can be pre-treated by conventionally known methods. The pre-treatment solution may be diluted by dispersing it in an organic solvent or water as needed, and then applied to the surface of the nonwoven fabric substrate by known methods such as immersion coating, spray coating, or foam coating, followed by drying. The pH and temperature of the pre-treatment solution may be adjusted according to the desired degree of treatment. 【0284】 The pretreatment method for nonwoven fabric substrates involves applying -SO3M to the fibers.1 (In the formula, M 1 (represents a monovalent cation) a monovalent group represented by -COOM 2 (In the formula, M 2 A monovalent group represented by (where is a monovalent cation), and -OP(O)(OX 1 )(OX 2 )(wherein, X 1 and X 2 The process may include a step of adding at least one functional group (hereinafter sometimes referred to as a "specific functional group") selected from the group consisting of monovalent groups (each independently representing a hydrogen atom or an alkyl group having 1 to 22 carbon atoms). 【0285】 M 1 Examples include H, K, Na, or ammonium ions which may have substituents. 2 Examples include H, K, Na, or ammonium ions which may have substituents. 1 or X 2 If it is an alkyl group, it is preferably an alkyl group having 1 to 22 carbon atoms, and more preferably an alkyl group having 4 to 12 carbon atoms. 【0286】 Fibers containing the above-mentioned specific functional groups (hereinafter sometimes referred to as "functional group-containing fibers") can be prepared, for example, by the following method. (i) A compound having the above-mentioned specific functional group is attached to the fiber material. The attachment of the compound may be such that a portion of the compound and a portion of the fiber are chemically bonded, to the extent that a sufficient amount of the above-mentioned specific functional group remains. (ii) Prepare a fiber in which the above-mentioned specific functional group is directly introduced into the material constituting the fiber. 【0287】 (i) For example, a functional group-containing fiber can be obtained by a functional group introduction step in which the fiber material is treated with a pretreatment solution containing one or more compounds having the above-mentioned specific functional group. 【0288】 There are no particular restrictions on the material of the fiber material, and examples include natural fibers such as cotton, linen, silk, and wool; semi-synthetic fibers such as rayon and acetate; synthetic fibers such as polyamide (nylon, etc.), polyester, polyurethane, and polypropylene; and composite fibers and blended fibers thereof.

Examples of such phenolic polymers include those containing at least one compound represented by the following general formula. 【0291】 [ka] [In formula (2), X 2 ha-SO3M 3 (In the formula, M 3 (where n represents a monovalent cation) or a group represented by the following general formula, where n is an integer between 20 and 3000. 【0292】 [ka] [In the formula, M 4 This represents a monovalent cation. 【0293】 The above M 3 Examples include H, K, Na, or ammonium ions which may have substituents. 【0294】 The above M 4 Examples include H, K, Na, or ammonium ions which may have substituents. 【0295】 The compound represented by the above general formula may be, for example, a formalin condensate of phenolsulfonic acid or a formalin condensate of sulfonated bisphenol S. 【0296】 The above-COOM 2 Examples of compounds having this property include polycarboxylic acid polymers. 【0297】 As polycarboxylic acid polymers, for example, polymers synthesized by conventionally known radical polymerization methods using acrylic acid, methacrylic acid, maleic acid, etc. as monomers, or commercially available polymers can be used. 【0298】 One method for producing polycarboxylic acid polymers is to add a radical polymerization initiator to an aqueous solution of the monomer and / or its salt, and heat the reaction at 30 to 150°C for 2 to 5 hours. At this time, alcohols such as methanol, ethanol, isopropyl alcohol, or aqueous solvents such as acetone may be added to the aqueous solution of the monomer and / or its salt. Examples of radical polymerization initiators include persulfates such as potassium persulfate, sodium persulfate, and ammonium persulfate, redox polymerization initiators using combinations of persulfates and sodium bisulfite, hydrogen peroxide, and water-soluble azo polymerization initiators.

Examples of alkali metals include sodium, potassium, and lithium, while examples of amine compounds include ammonia, monoethanolamine, diethanolamine, and triethanolamine. 【0301】 The weight-average molecular weight of the polycarboxylic acid polymer is preferably 1,000 to 20,000, and more preferably 3,000 to 15,000, from the viewpoint of obtaining good water repellency in the resulting nonwoven fabric product. 【0302】 For polycarboxylic acid polymers, commercially available products such as "NeoCrystal 770" (manufactured by Nikka Chemical Co., Ltd., product name) and "Cellopol PC-300" (manufactured by Sanyo Chemical Industries, Ltd., product name) can be used. 【0303】 The above - OP(O)(OX 1 )(OX 2 Examples of compounds having the following general formula include phosphate ester compounds. [ka] [In the formula, X 1or X 2 This is synonymous with the above, X 3 This represents an alkyl group with 1 to 22 carbon atoms. 【0304】 As the phosphate ester compounds mentioned above, phosphate monoesters, diesters, and triesters in which the alkyl ester portion has an alkyl group having 1 to 22 carbon atoms, as well as mixtures thereof, can be used. 【0305】 From the viewpoint of obtaining a nonwoven fabric product with good water repellency, it is preferable to use lauryl phosphate ester or decyl phosphate ester. 【0306】 For the phosphate ester compound, commercially available products such as "Phosphanol ML-200" (manufactured by Toho Chemical Industry Co., Ltd., trade name) can be used. 【0307】 The pretreatment solution containing one or more compounds having the above-mentioned specific functional groups can, for example, be an aqueous solution of the compounds described above. The pretreatment solution may also contain acids, alkalis, surfactants, chelating agents, etc. 【0308】 Methods for treating fibrous materials with the above-mentioned pretreatment solution include, for example, padding, immersion, spraying, and coating. For padding, for example, methods using padding equipment described on pages 396-397 of the Dictionary of Textile Dyeing and Processing (published in 1963 by Nikkan Kogyo Shimbun) and pages 256-260 of Color Dyeing Chemistry III (published in 1975 by Jikkyo Shuppan Co., Ltd.) can be used. For coating, for example, methods using coating machines described on pages 473-477 of the General Catalog of Dyeing and Finishing Equipment (published in 1981 by Senryo-sha) can be used. For immersion, for example, methods using batch-type dyeing machines described on pages 196-247 of the General Catalog of Dyeing and Finishing Equipment (published in 1981 by Senryo-sha) can be used, and liquid flow dyeing machines, air flow dyeing machines, drum dyeing machines, winch dyeing machines, washer dyeing machines, cheese dyeing machines, etc. can be used. Examples of spray treatments include air sprays that atomize the treatment solution using compressed air, and air sprays that use a hydraulic atomization system. The concentration of the treatment solution and the treatment conditions such as heat treatment after application can be adjusted as appropriate, taking into account the purpose, performance, and other conditions. If the pretreatment solution contains water, it is preferable to dry it to remove the water after it has been applied to the fiber material. There are no particular restrictions on the drying method, and either a dry heat method or a wet heat method may be used. There are no particular restrictions on the drying temperature, but for example, drying at room temperature to 200°C for 10 seconds to several days is sufficient. If necessary, after drying, heat treatment may be performed at a temperature of 100 to 180°C for about 10 seconds to 5 minutes. 【0309】 Furthermore, if the fiber material is to be dyed, the pretreatment with the pretreatment solution may be performed before dyeing or in the same bath as the dyeing. However, if reducing soaping is performed, there is a risk that the compounds having the specific functional groups (e.g., phenolic polymer compounds, etc.) that have been adsorbed during the process may be removed. Therefore, it is preferable to perform the pretreatment after reducing soaping following dyeing. 【0310】 The treatment temperature during the immersion process can be 60 to 130°C. The treatment time can be 5 to 60 minutes. 【0311】 In the functional group introduction step using the pretreatment solution, it is preferable to treat the material in such an amount that the amount of compound having the specified functional group attached is 1.0 to 7.0 parts by weight per 100 parts by weight of the fiber material. Within this range, a high level of both durable water repellency and texture can be achieved. 【0312】 The pretreatment solution is preferably adjusted to a pH of 3-5. pH adjustment can be done using pH adjusting agents such as acetic acid or malic acid. 【0313】 The pretreatment solution may also contain salt to effectively adsorb the compound having the above-mentioned specific functional group onto the fiber material through a salting-out effect. Examples of salts that can be used include sodium chloride. Examples include sodium carbonate, ammonium sulfate, and sodium sulfate. 【0314】 In the functional group introduction step using a pretreatment solution, it is preferable to remove any compounds having the specified functional groups that have been excessively treated. One method of removal is washing with water. By performing sufficient removal, it is possible to suppress the inhibition of the development of water repellency in the subsequent water-repellent treatment, and in addition, the texture of the resulting nonwoven fabric product will be improved. Furthermore, it is preferable to thoroughly dry the resulting functional group-containing fibers before contacting them with a hydrocarbon-based water repellent. 【0315】 (ii) Examples of fibers in which the above-mentioned specific functional groups are directly introduced into the material constituting the fiber include cationic dyeable polyester (CD-PET). 【0316】 From the viewpoint of obtaining good water repellency in the resulting textile product, the functional group-containing fibers preferably have a surface zeta potential of -100 to -0.1 mV, and more preferably -50 to -1 mV. The surface zeta potential of the fibers can be measured, for example, using the zeta potential / particle size measurement system ELSZ-1000ZS (manufactured by Otsuka Electronics Co., Ltd.). 【0317】 Although embodiments have been described above, it should be understood that various modifications to the form and details are possible without departing from the spirit and scope of the claims. [Examples] 【0318】 The present disclosure will be described in detail below with reference to examples, but the present disclosure is not limited to these examples. 【0319】 <Testing Method> The examination procedure is as follows: 【0320】 [KIT Exam] Oil resistance (KIT method) was measured according to TAPPI T-559cm-02. The KIT test solution is a mixture of castor oil, toluene, and heptane in the ratios shown in Table 1. One drop of the test solution shown in the table below was placed on paper, and the degree of oil penetration was observed after 15 seconds. The highest oil resistance score given by the KIT test solution that did not show penetration was defined as the oil resistance. A higher KIT test solution number indicates higher oil resistance. 【0321】 [Table 1] 【0322】 [High-temperature oil resistance test] A small amount of commercially available olive oil was dripped onto the prepared oil-resistant paper, and it was placed in a 70°C oven for 5 minutes before being removed and the oil wiped off. After that, the degree to which the oil was absorbed into the oil-resistant paper was visually observed and evaluated according to the following criteria. ○: No oil stains observed. ○△: Spots of oil stains are observed. △: Oil stains are observed on less than half of the oil droplet contact surface. ×: Oil stains are observed on more than half of the oil droplet contact surface. 【0323】 <Example of synthesis> [Synthesis Example 1] A 500 ml reactor equipped with a stirrer, thermometer, reflux condenser, dropping funnel, nitrogen inlet, and heating device was prepared, and 100 parts of the solvent methyl ethyl ketone (MEK) were added. Next, under stirring, monomers consisting of 78 parts of stearyl amide ethyl acrylate (C18AmEA, melting point: 70°C), 16 parts of hydroxybutyl acrylate (HBA, Tg: -40°C), and 6 parts of dimethylaminoethyl methacrylate (DM) (total monomers: 100 parts), and 1.2 parts of the initiator perbutyl PV (PV) were added in this order. This mixture was mixed and stirred under a nitrogen atmosphere at 65-80°C for 12 hours to carry out copolymerization. The solid content concentration of the resulting copolymer-containing solution was 50% by weight. The obtained copolymer solution was added to water containing approximately 3 g of acetic acid and dispersed. Then, the MEK was removed by heating using an evaporator and under reduced pressure to obtain a milky white copolymer aqueous dispersion (volatile organic solvent content of 1% by weight or less). Deionized water was added to obtain an aqueous dispersion with a solid content of 15% by weight. The melting point of this copolymer was 70°C. 【0324】 [Synthesis Example 2] The procedure was carried out in the same manner as in Synthesis Example 1, except that 75 parts of stearyl acrylate (StA, melting point: 30°C), 22 parts of hydroxybutyl acrylate (HBA, Tg: -40°C), and 3 parts of dimethylaminoethyl methacrylate (DM) were used instead of stearyl amide ethyl acrylate (C18AmEA, melting point: 70°C), and a milky white copolymer aqueous dispersion (containing 1% by weight or less of volatile organic solvents) was obtained. Deionized water was added to obtain an aqueous dispersion with a solid content of 15% by weight. The melting point of this copolymer was 48°C. 【0325】 <Examples and Comparative Examples> [Example 1] It is made from a mixed pulp of LBKP (bleached hardwood kraft pulp) and NBKP (bleached softwood kraft pulp), with a basis weight of 47 g / m². 2 The paper density is 0.77 g / cm². 3 The air permeability is 200 seconds, and the Cobb value is 51 g / m². 2 A paper substrate was used as the base paper. The oil resistance of this base paper was KIT value 0, and the practical oil test result was 1. Using the aqueous dispersion of the copolymer obtained in Synthesis Example 1 as an oil-resistant agent, oil-resistant paper (processed paper) was obtained according to the following formulation. 【0326】 A treatment solution was prepared by mixing the aqueous dispersion of the copolymer obtained in Synthesis Example 1 with an aqueous dispersion of starch solution and glyoxal as a crosslinking agent. The pH of the treatment solution was adjusted to 3.5-4.2 using a certain amount of malic acid aqueous solution, and the solid content concentrations of the copolymer, starch, and crosslinking agent were adjusted to 1.4% by weight, 14% by weight, and 0.5% by weight, respectively. 【0327】 The base paper was treated with a processing solution at approximately 50°C using a size press, and then dried in a drum dryer to obtain oil-resistant paper. Table 2 shows the dry coating amount of the obtained oil-resistant paper and the results of the kit test of the oil-resistant paper.
