[0018] When the composition contains a liquid medium (for example, the composition is an aqueous dispersion), the hardness of the residue obtained by removing the liquid medium from the composition may be as follows. The Shore A hardness [PEAK] of the peak strength during the test may be 0.5 or more, 1.0 or more, 1.5 or more, 2.0 or more, 2.5 or more, 3.0 or more, 4.0 or more, 5.0 or more, 7.5 or more, or 10.0 or more, and may also be 80 or less, 75 or less, 70 or less, 65 or less, or 60 or less.

[0019] [Hydrophobic compound (A)] The hydrophobic compound (A) in the present disclosure is a mixture composed of a hydrophobic compound (A1) and a hydrophobic compound (A2) different from the hydrophobic compound (A1).

[0020] [Properties, etc.] The properties that the hydrophobic compound (A), the hydrophobic compound (A1), and the hydrophobic compound (A2) may have are shown below. In the following, when referring to the properties of the hydrophobic compound (A) itself, the hydrophobic compound (A) is intended to be a mixture obtained by melt-mixing the hydrophobic compound (A1) and the hydrophobic compound (A2) at a temperature equal to or higher than their melting points and then cooling to room temperature.
[0021] (Dissolution properties) The hydrophobic compound (A1) and the hydrophobic compound (A2) are hydrophobic and have low water solubility. Independently, the hydrophobic compound (A1) and the hydrophobic compound (A2) may each have a water solubility at 25 °C of 3.0 g / l or less, 1.0 g / l or less, 0.5 g / l or less, 0.1 g / l or less, or 0.01 g or less, for example, 1.0 g / l or less. The water solubility can be calculated from the amount of dissolution at the time when, while adding the compound little by little to a predetermined amount of water (25 °C), no more dissolution occurs (such as floating, precipitation, deposition, turbidity, etc.). A compound with high water solubility (for example, a compound that is a water-miscible liquid) cannot be said to be a hydrophobic compound.
[0022] The solubility parameters (SP values) of the hydrophobic compounds (A1) and (A2) may each independently be 3.0 or more, 4.0 or more, 5.0 or more, 6.0 or more, 7.0 or more, 8.0 or more, 9.0 or more, 10.0 or more, or 11.0 or more, and may each independently be 15.0 or less, 14.0 or less, 13.0 or less, 12.0 or less, 10.0 or less, 9.0 or less, or 8.0 or less, preferably 10.5 or less, particularly 10.0 or less. The SP value can be determined by Fedors' formula (Polym. Eng. Sci., 14[2], 147 (1974)). Only the hydrophobic compound (A1), only the hydrophobic compound (A2), or both may satisfy the above range, preferably both satisfy the above range.
[0023] The difference in the SP value between the hydrophobic compound (A1) and the hydrophobic compound (A2) may be more than 0, 0.1 or more, 0.2 or more, 0.3 or more, 0.4 or more, 0.5 or more, 0.6 or more, 0.7 or more, 0.8 or more, 0.9 or more, 1.0 or more, 2.0 or more, 3.0 or more, 4.0 or more, or 5.0 or more, and may also be 6.0 or less, 5.0 or less, 4.0 or less, 3.0 or less, 2.0 or less, 1.5 or less, 1.0 or less, 0.8 or less, 0.6 or less, or 0.5 or less, preferably 5.0 or less, more preferably 3.0 or less. The hydrophobic compound (A1) may have a larger value, or the hydrophobic compound (A2) may have a larger value. When there are a plurality of compounds in each of the hydrophobic compounds (A1) and (A2), a weighted average based on the weight ratio may be used for calculating each value. In this specification, unless otherwise specified, the difference is an absolute difference.
[0024] The octanol / water partition coefficient (logPow) of the hydrophobic compounds (A1) and (A2) may each independently be 0 or more, 0.1 or more, 0.3 or more, 0.5 or more, 1 or more, 1.5 or more, 2.0 or more, 2.5 or more, 3.0 or more, 3.5 or more, 4.0 or more, 4.5 or more, 5.0 or more, 5.5 or more, or 6.0 or more, preferably 0.5 or more, 1.5 or more, 2.5 or more, or 3.5 or more, and may also be 10.0 or less, 9.0 or less, 8.0 or less, 7.0 or less, 6.0 or less, 5.0 or less, 4.0 or less, 3.0 or less, 2.0 or less, or 1.0 or less. Only the hydrophobic compound (A1), only the hydrophobic compound (A2), or both may satisfy the above range, preferably both satisfy the above range.
[0025] The difference in the octanol / water partition coefficient (logPow) between the hydrophobic compound (A1) and the hydrophobic compound (A2) may be greater than 0, 0.1 or more, 0.3 or more, 0.5 or more, 1.0 or more, 1.5 or more, or 2.0 or more, and may also be 5.0 or less, 4.5 or less, 4.0 or less, 3.0 or less, 2.5 or less, 2.0 or less, 1.5 or less, 1.0 or less, 0.5 or less, 0.3 or less, or 0.1 or less, preferably 2.5 or less, more preferably 1.0 or less. The hydrophobic compound (A1) may have a larger value, or the hydrophobic compound (A2) may have a larger value. In each of the hydrophobic compounds (A1) and (A2), when there are a plurality of compounds, a weighted average based on the weight ratio may be used for calculating each value.
[0026] The HLB value (hydrophile-lipophile balance) of the hydrophobic compound (A2) may be 0.5 or more, or 1.0 or more, and may also be 11.5 or less, 11.0 or less, 10.5 or less, 10.0 or less, 9.5 or less, 9.0 or less, 8.5 or less, 8.0 or less, 7.5 or less, or 7.0 or less. By being below the above upper limit value, the effects of the present disclosure can be achieved well. The HLB value (hydrophile-lipophile balance) was conceived by W.C. Griffin and is a numerical value given to nonionic surfactants, which represents numerically the balance of the strength between the lipophilic group (such as an alkyl group) and the hydrophilic group (such as a polyoxyalkylene chain) of the nonionic surfactant. In the present invention, the HLB value adopts the calculated value by the Griffin method (references: W.G. Griffin, J. Soc. Cosmetic Chemists, 1, 311 (1949) and W.G. Griffn, J. Soc. Cosmetic Chemists, 5, 249 (1954)). For those with catalog values, the catalog values may be adopted as a simple judgment method, but when the catalog value and the calculated value are different, the calculated value shall be adopted. The HLB value of the hydrophobic compound (A1) may be larger than that of the hydrophobic compound (A2), or the hydrophobic compound (A2) may have a larger value. In each of the hydrophobic compounds (A1) and (A2), when there are multiple compounds, a weighted average based on the weight ratio may be used for calculating each value.
[0027] (Thermal properties) The endothermic peak in the DSC of the hydrophobic compound (A1) (alone) may shift to a lower temperature when mixed with the hydrophobic compound (A2) to form the hydrophobic compound (A) (mixture). The endothermic peak temperature in the differential scanning calorimetry of the hydrophobic compound (A1) may shift to a lower temperature by 2 °C or more and 80 °C or less in the differential scanning calorimetry of the hydrophobic compound (A). The endothermic peak that shifts to a lower temperature may be any peak of the hydrophobic compound (A1) (for example, the maximum peak, any endothermic peak with a peak intensity in the top 30%, etc.), and at least 1 (for example, 50% or more, 70% or more, 100%) of all the peaks in the range of -50 °C to 300 °C (for example, -30 °C to 240 °C, particularly -20 °C to 180 °C, particularly 0 °C to 180 °C) may shift to a lower temperature. The low-temperature shift width may be 0.5 °C or more, 1 °C or more, 1.5 °C or more, 2 °C or more, 2.5 °C or more, 3 °C or more, 4 °C or more, 6 °C or more, 8 °C or more, 10 °C or more, 12 °C or more, 15 °C or more, 20 °C or more, or 30 °C or more, and may also be 80 °C or less, 75 °C or less, 65 °C or less, 55 °C or less, 45 °C or less, 35 °C or less, 25 °C or less, 20 °C or less, 15 °C or less, 12 °C or less, 11 °C or less, or 10 °C or less, for example 20 °C or less. In one aspect, it may be 0.5 °C or more and 80 °C or less, particularly 0.5 °C or more and 20 °C or less, 3 °C or more and 12 °C or less, or 3 °C or more and 11 °C or less. By combining two kinds of hydrophobic compounds, it is considered that the thermal properties change and a low-temperature shift of the endothermic peak in DSC occurs. The hydrophobic compound (A1) may have one or more endothermic peaks at 45 °C or more, and the endothermic peak may shift to a lower temperature. Preferably, the endothermic peak of the hydrophobic compound (A1) that shifts to a lower temperature is the endothermic peak on the highest temperature side in the measurement range, and may be, for example, a peak associated with melting (melting point peak). Note that the endothermic peak does not include the endothermic peak due to the decomposition of the compound, and is the endothermic peak within the range where the compound does not decompose. In the case of a compound that decomposes without melting, it is understood that the melting point of the compound is at least the decomposition temperature or higher.
[0028] The measurement conditions of DSC may be as follows. After cooling DSC to -20°C or lower under a nitrogen atmosphere, the endothermic peak observed during the heating process to 180°C or higher at a rate of 10°C / min thereafter is measured. The endothermic heat quantity is calculated by calculating the heat quantity in the range of ±10°C of the endothermic peak temperature.
[0029] The melting points of the hydrophobic compounds (A1) and (A2) may each independently be -100°C or higher, -75°C or higher, -50°C or higher, -25°C or higher, 0°C or higher, 30°C or higher, 40°C or higher, 50°C or higher, 60°C or higher, 80°C or higher, 100°C or higher, or 120°C or higher, preferably 40°C or higher, and may each independently be 250°C or lower, 225°C or lower, 200°C or lower, 150°C or lower, 130°C or lower, 120°C or lower, 110°C or lower, 100°C or lower, 80°C or lower, 50°C or lower, 40°C or lower, 30°C or lower, 20°C or lower, 10°C or lower, 0°C or lower, or -10°C or lower. Only the hydrophobic compound (A1), only the hydrophobic compound (A2), or both may satisfy the above range, preferably both satisfy the above range. The hydrophobic compound (A1) may be solid at room temperature (melting point 30°C or higher), for example 50°C or higher, and the melting point of the hydrophobic compound (A2) may be 40°C or lower, for example 30°C or lower (less than 30°C), particularly liquid at room temperature (melting point 20°C or lower). In particular, the melting point of the hydrophobic compound (A1) may be 50°C or higher, and the melting point of the hydrophobic compound (A2) may be 40°C or lower.

Further, a modifier which is a halide or an epoxy compound is reacted with the hydroxy group of the polyol to form an ether bond, thereby producing a polyol-modified product. Those skilled in the art can appropriately design the reaction conditions between the polyol and the modifier, such as the use of a catalyst (for example, an acid catalyst or a base catalyst) and the use of a condensing agent, according to the target product.

[0382] <Method for manufacturing the product> The method for manufacturing the product in the present disclosure may include a step of treating a substrate with a composition containing the hydrophobic compound (A) in the present disclosure as a treatment agent (particularly a repellent).
[0383] The substrate to be treated with the treatment agent in the present disclosure is not limited, but is preferably a fiber substrate, which may be a textile substrate or a pulp substrate, particularly a pulp substrate.
[0384] Examples of the fiber substrate include animal and plant natural fibers such as cotton, hemp, 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 fiber, carbon fiber, and asbestos fiber, or mixed fibers thereof. Fiber products include woven fabrics, knitted fabrics, non-woven fabrics, fabrics in the form of clothing (e.g., water-repellent clothing, e.g., raincoats), and carpets. However, the fibers, yarns, and intermediate fiber products (e.g., sliver or roving, etc.) in the state before being made into fabrics may also be treated.
[0385] The substrates to be treated with the treatment agent of the present disclosure are not limited to fiber substrates, and other examples include stone, filters (e.g., electrostatic filters), dust masks, parts of fuel cells (e.g., gas diffusion electrodes and gas diffusion supports), glass, wood, leather, fur, asbestos, bricks, cement, metals and oxides, ceramic products, plastics, painted surfaces, and plasters, etc.
[0386] When the substrate is glass, the manufactured glass product may be an optical member. Some layer (or film), such as a hard coat layer or an antireflection layer, may be formed on the surface (outermost layer) of the glass substrate. Either a single-layer antireflection layer or a multilayer antireflection layer may be used for the antireflection layer. Examples of inorganic substances that can be used for the antireflection layer include SiO2, SiO, ZrO2, TiO2, TiO, Ti2O3, Ti2O5, Al2O3, Ta2O5, CeO2, MgO, Y2O3, SnO2, MgF2, WO3, and the like. These inorganic substances may be used alone or in combination of two or more thereof (for example, as a mixture). When forming a multilayer antireflection layer, it is preferable to use SiO2 and / or SiO for its outermost layer. When the article to be manufactured is an optical glass component for a touch panel, it may have a thin film using a transparent electrode, such as indium tin oxide (ITO) or indium zinc oxide, on a part of the surface of the substrate (glass). Further, depending on its specific specifications and the like, the substrate may have an insulating layer, an adhesive layer, a protective layer, a decorative frame layer (I-CON), a fogging film layer, a hard coating film layer, a polarizing film, a retardation film, and a liquid crystal display module.
[0387] 〔Method for manufacturing pulp product〕 The method for manufacturing the product in the present disclosure is preferably a method for manufacturing a pulp product, and may include a step of treating a pulp substrate with a sizing agent. The pulp substrate is treated with a sizing agent to obtain a pulp composition. The obtained pulp composition can be subjected to treatment steps such as drying, heating, and molding, if necessary, to obtain a pulp product.
[0388] Regarding the pulp base material and the type and composition of the water-repellent agent, the aspects in the description of the above-mentioned "pulp composition" are incorporated by reference. The composition of the present disclosure can be applied to the base material by a conventionally known method as a treatment agent (particularly a water-repellent agent). As a treatment method, the water-repellent agent in the present disclosure can be dispersed and diluted in an organic solvent or water if necessary, and adhered to the inside and / or surface of the pulp base material by a known method such as dip coating, spray coating, foam coating, etc., and then dried. After drying, a pulp product with the solid component of the water-repellent agent adhered thereto can be obtained. Further, if necessary, it may be applied together with a suitable cross-linking agent and cured. The concentration of the water-repellent agent in the treatment agent brought into contact with the pulp base material may be appropriately changed depending on the application, but may be 0.01 to 10% by weight, for example, 0.05 to 5% by weight.
[0389] The water-repellent agent can be applied to the pulp base material by any of the methods known for treating the pulp base material with a liquid. The pulp base material may be immersed in the water-repellent agent, or the pulp base material and the water-repellent agent may be mixed, or a solution may be adhered or sprayed onto the pulp base material. The treated pulp base material is preferably dried and cured by heating in order to exhibit water-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. In the present disclosure, the heating time may be 5 seconds to 60 minutes, for example, 30 seconds to 3 minutes.
[0390] As a method for treating the pulp base material, an internal addition treatment method in which a water-repellent agent is added to the pulp before papermaking (for example, pulp slurry), or an external addition treatment method in which a water-repellent agent is applied to the pulp after papermaking (for example, pulp product) can be used. Examples of the internal addition treatment method include mixing, immersion, etc., and may include a step of adding a water-repellent agent to the pulp slurry and stirring and mixing. Examples of the external addition treatment method include spraying, coating, etc., and specifically include a pond type two-roll size press, a gate roll type, and a rod metering size press, etc. The treatment may be an external addition treatment or an internal addition treatment. For example, when the pulp base material is paper, it may be coated on the paper, or a solution may be adhered or sprayed onto the paper, or it may be treated by mixing with the pulp slurry before papermaking.
[0391] The treatment method may be an internal addition treatment in which a sizing agent is added to the pulp slurry before papermaking. As the internal addition treatment, it may include one or more of the steps of adding a sizing agent to the pulp slurry and stirring and mixing, suction-dehydrating the pulp composition prepared in this step through a reticular body of a predetermined shape to deposit the pulp composition to form an intermediate of a pulp molded product, and molding and drying the intermediate of the pulp molded product with a heated mold to obtain a pulp molded product, but it is not limited to this. The treated paper may optionally be heat-treated depending on the properties of the paper after simple drying at room temperature or high temperature. The temperature of the heat treatment may be 150 °C or higher, 180 °C or higher, or 210 °C or higher, may be 300 °C or lower, 250 °C or lower, or 200 °C or lower, and particularly may be 80 °C to 180 °C. By performing the heat treatment within such a temperature range, excellent oil resistance, water resistance, etc. can be exhibited. An external addition treatment may be performed on the internally added pulp base material to treat it with a sizing agent, and further wax and further paper strengthening agent may be adhered to the surface.
[0392] The treatment method may be an external addition treatment in which a sizing agent is applied to the pulp base material after papermaking. The size press for the external addition treatment can also be classified as follows according to the coating method. One coating method is a so-called pond-type two-roll size press in which a coating liquid (sizing liquid) is supplied to a nip portion formed by passing paper between two rubber rolls to create a coating liquid reservoir called a pond, and the sizing liquid is applied to both sides of the paper by passing the paper through this coating liquid reservoir. Another coating method is a gate roll type in which the sizing liquid is applied by a surface transfer type, and a rod metering size press. In the pond-type two-roll size press, the sizing liquid easily penetrates into the paper, and in the surface transfer type, the sizing liquid components tend to remain on the surface of the paper. The surface transfer type has a coating layer that tends to remain on the surface of the paper and has more coating layers formed on the surface than the pond-type two-roll size press. In the present disclosure, performance can be imparted to the paper even when the former pond-type two-roll size press is used. The paper treated in this way can exhibit excellent oil resistance and / or water resistance, etc. by optionally undergoing a heat treatment in a temperature range up to 300°C, for example up to 200°C, particularly in the range of 80°C to 180°C, depending on the properties of the paper, after simple drying at room temperature or high temperature.
[0393] As described above, although the embodiments have been explained, it will be understood that various changes in form and details are possible without departing from the spirit and scope of the claims.
