     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an antiviral wiper. 
     2. Description of the Related Art 
       Norovirus  is a virus classified into the genus  Norovirus  belonging to the family Caliciviridae, and is known as a pathogen that causes food poisoning and the like. Recently, for preventing norovirus infection, the development of a wiper obtained by impregnating a base fabric such as a non-woven fabric with a liquid agent having anti-norovirus activity has been required. 
     For example, JP2013-047196A describes a norovirucidal liquid agent containing proanthocyanidin (compound having a phenolic hydroxyl group). 
     SUMMARY OF THE INVENTION 
     The inventors of the present invention prepared an antiviral liquid agent containing a compound having a phenolic hydroxyl group with reference to JP2013-047196A, prepared a wiper by impregnating a base fabric (for example, a non-woven fabric) with the liquid agent, and examined the wiper. As a result, the inventors have found that sometimes the antiviral activity of the wiper deteriorates after long-term storage depending on the material of the base fabric. In other words, it has been revealed that the storage stability of the antiviral wiper needs to be further improved. 
     Furthermore, there is also a constant demand for further improvement of the antiviral activity of the antiviral wiper. 
     An object of the present invention is to provide an antiviral wiper having excellent antiviral activity and excellent storage stability.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Hereinafter, the present invention will be specifically described. 
     The following constituents will be described based on typical embodiments of the present invention in some cases, but the present invention is not limited to the embodiments. 
     In the present specification, the rage of numerical values described using “to” means a range including the numerical values listed before and after “to” as the lower limit and the upper limit. 
     In the present specification, in a case where a plurality of substituents, linking groups, and the like (hereinafter, also called substituents and the like) are represented by a specific reference or in a case where a plurality of substituents and the like is collectively specified, the substituents and the like may be the same as or different from each other respectively. The same is true of a case where the number of substituents and the like is specified. 
     Furthermore, in the present specification, in a case where there is no description regarding whether a group (atomic group) is substituted or unsubstituted, the group includes a group having no substituent and a group having a substituent. For example, “alkyl group” includes not only an alkyl group having no substituent (unsubstituted alkyl group) but also an alkyl group having a substituent (substituted alkyl group). 
     [Antiviral Wiper] 
     The antiviral wiper according to an embodiment of the present invention (hereinafter, also called “wiper”) is an antiviral wiper having a base fabric and a liquid agent with which the base fabric is impregnated. 
     The content of a cellulosic fiber in the base fabric is equal to or lower than 70% by mass with respect to the total mass of fibers constituting the base fabric. 
     The liquid agent is alkaline and contains a compound X having a pKa of 7.0 to 15.0 and a solvent containing at least an alcohol, and the content of the alcohol is 40% to 100% by mass with respect to the total mass of the solvent. 
     Due to the presence of the compound X having a pKa of 7.0 to 15.0, the wiper has remarkably excellent antiviral activity (particularly, antiviral activity against feline calicivirus (norovirus-related species)). In addition, the antiviral activity of the wiper hardly deteriorates even after long-term storage (in other words, the wiper has excellent storage stability). 
     Furthermore, it has been confirmed that the wiper has excellent antimicrobial activity against other viruses and microorganisms such as bacteria and fungi (for example, adenoviruses, influenza viruses, herpes viruses,  Trichophyton, Candida Albicans, Aspergillus, Escherichia coli, Staphylococcus , and the like). 
     Details of the mechanism of action of the present invention are unclear, but are assumed to be as below by the inventors of the present invention. 
     In the above liquid agent, the compound X having a pKa of 7.0 to 15.0 functions as an active component (antiviral component). Presumably, in a case where the liquid agent is alkaline, anions formed by the dissociation of hydrogen ions from the compound X (hereinafter, also called “compound X-derived anions”; for example, in a case where the compound X is a compound having a phenolic hydroxyl group, phenoxide anions can be generated by the dissociation of hydrogen ions) may cause the deprotonation of acid groups present on the surface of viruses, and hence the viruses may be inactivated. In addition, the inventors of the present invention consider that a predetermined amount of alcohol contained in the solvent may be one of the factors enabling the liquid agent to have excellent antiviral activity (and enabling the wiper to have excellent antiviral activity). 
     Furthermore, by the inventors of the present invention, it has been revealed that the antiviral activity of a wiper formed using a base fabric containing a large amount of cellulosic fiber seriously deteriorates after long-term storage. The reason is assumed to be as below. The hydroxyl groups in the cellulosic fiber may interact with each other by forming hydrogen bonds and adsorb the compound X-derived anions. Furthermore, a pH adjuster (for example, a base such as sodium hydroxide) that can be contained in the liquid agent may be substituted with hydrogen atoms in the hydroxyl groups in the cellulosic fiber, and hence the pH of the liquid agent may change. Consequently, the amount of compound X-derived anions generated in the liquid agent may be relatively reduced. 
     Regarding this problem, by the inventors of the present invention, it has been revealed that in a case where the content of the cellulosic fiber in the base fabric is equal to or lower than 70% by mass with respect to the total mass of fibers, the deterioration of antiviral activity can be inhibited even after the long-term storage. 
     Hereinafter, first, the formulation of the liquid agent contained in the wiper will be described. 
     [Liquid Agent] 
     &lt;Compound X&gt; 
     The liquid agent contains a compound X. 
     The compound X is a compound which has a pKa of 7.0 to 15.0 and is in an anionic state under alkaline conditions by the dissociation of hydrogen ions. In a case where the compound X has a plurality of pKa values (that is, in a case where the compound X is an acid that undergoes multi-stage dissociation), at least one of the plurality of pKa values may be 7.0 to 15.0. 
     The pKa of the compound X is preferably 7.0 to 12.0. 
     Examples of the compound X include compounds having a phenolic hydroxyl group, a mercapto group, or an amine group as a functional group. Among these, a compound having a phenolic hydroxyl group is preferable because this compound is stable in an anionic state and is a safe material. 
     In a case where the compound X is a compound having a phenolic hydroxyl group, a mercapto group, or an amine group as a functional group, it is preferable that the pKa of the phenolic hydroxyl group, the mercapto group, or the amine group is 7.0 to 15.0. 
     In a case where the compound X is a compound having a phenolic hydroxyl group, a mercapto group, or an amine group as a functional group, the number of the above functional groups in the compound X is not particularly limited and may be 1 or equal to or greater than 2. 
     “pKa value” in the present specification is “pKa value” calculated using software (Chem Bio Draw Ultra ver. 12.0. (CambridgeSoft Corporation, USA)). 
     The content of the compound X (particularly, the compound having a phenolic hydroxyl group) in the above liquid agent is not particularly limited. In view of further improving the antiviral activity of the wiper, the content of the compound X with respect to the total mass of the liquid agent is preferably equal to or higher than 0.05% by mass, more preferably equal to or higher than 0.1% by mass, and even more preferably equal to or higher than 0.2% by mass. The upper limit thereof is not particularly limited, but is preferably equal to or lower than 5.0% by mass, more preferably equal to or lower than 1.0% by mass, and even more referably equal to or lower than 0.5% by mass. 
     One kind of compound X (particularly, the compound having a phenolic hydroxyl group) may be used singly, or two or more kinds of compounds X may be used in combination. In a case where two or more kinds of compounds X (particularly, the compounds having phenolic hydroxyl groups) are used in combination, the total content thereof is preferably within the above range.

     In the formula, Rx ma  represents a hydrogen atom, a halogen atom, an alkyl group (the alkyl group may be linear or branched or may have a cyclic structure, foe number of carbon atoms in the alkyl group is preferably 1 to 20, and foe alkyl group is more preferably a methyl group), or a perfluoroalkyl group (the perfluoroalkyl group may be linear or branched or may have a cyclic structure, foe number of carbon atoms in the perfluoroalkyl group is preferably 1 to 20, and the perfluoroalkyl group is more preferably a trifluoromethyl group). 
     Lx represents a single bond or a divalent linking group. The divalent linking group has the same definition as foe divalent linking group represented by L 1-2 . 
     X represents the residue of Formula (1F). 
     As described above, foe compound F has, as a 6-membered aromatic ring group substituted with two or more hydroxyl groups, only a residue remaining after one or more hydrogen atoms excluding a hydrogen atom in a hydroxyl group are removed from foe compound represented by Formula (1F). 
     That is, foe compound F has, as a 6-membered aromatic ring group substituted with two or more hydroxyl groups, only a 6-membered aromatic ring group in which some of foe hydroxyl groups are arranged in meta position with the rest of foe hydroxyl groups. 
     In other words, foe compound A does not have a 6-membered aromatic ring group substituted with two or more hydroxyl groups in which two hydroxyl groups are arranged in ortho or para position. 
     The 6-membered aromatic ring group also includes a 6-membered aromatic ring group incorporated into a polycyclic group. For example, the compound A does not have a residue which remains after one or more hydrogen atoms other than a hydrogen atom in a hydroxyl group are removed from 1,2-dihydroxynaphthalene, 1,4-dihydroxynaphthalene, or 1,2,4-trihydroxynaphthalene. 
     The 6-membered aromatic ring group in which two hydroxyl groups are arranged at ortho or para position turns into a quinone derivative by oxidation. In contrast, foe 6-membered aromatic ring group (residue of Formula (1F)) in which two hydroxyl groups are arranged at meta position is difficult to form a quinone derivative due to foe arrangement of the hydroxyl groups. Therefore, this group is chemically more stable than the 6-membered aromatic ring group in which two hydroxyl groups are arranged at ortho or para position. Accordingly, because the compound F has only the residue of Formula (1F) as the 6-membered aromatic ring group substituted with two or more hydroxyl groups, the storage stability of the liquid agent is improved. In a case where a substituent having a Hammett substituent constant σ p  higher than 0 is introduced into the 6-membered aromatic ring group (residue of Formula (1F)) in which two hydroxyl groups are arranged at meta position, the storage stability of the liquid agent is further improved. 
     (Compound G) 
     The compound G is a compound represented by Formula (2G). The compound G is also a 6-membered aromatic ring group in which all the hydroxyl groups are arranged at meta position. Therefore, this compound is chemically stable and has excellent storage stability.

     The above liquid agent contains a solvent. The content of the solvent in the liquid agent is not particularly limited. The content of the solvent with respect to the total mass of the liquid agent is preferably 0.01% to 99.8% by mass and more preferably 0.1% to 99.7% by mass. The solid content means components in the liquid agent except for a solvent. Even though the solid content is liquid, it is calculated as solid content. 
     In the liquid agent according to an embodiment of the present invention, tire content of an alcohol (total content of alcohols in a case where the liquid agent contains a plurality of alcohols) with respect to the total mass of the solvent is equal to or higher than 40% by mass. In view of further improving the antiviral activity, the content of the alcohol is preferably higher than 50% by mass, and more preferably equal to or higher than 60% by mass. The upper limit of the content of the alcohol is not particularly limited. The upper limit with respect to the total mass of the solvent is, for example, equal to or lower than 100% by mass, and preferably equal to or lower than 80% by mass. 
     One kind of alcohol may be used singly, or two or more kinds of alcohols may be used in combination. In a case where two or more kinds of alcohols are used in combination, the total content thereof is preferably within the above range. 
     In the present specification, an alcohol means a compound having an alcoholic hydroxyl group, and does not include a compound having a phenolic hydroxyl group. 
     The alcohol is not particularly limited, but is, for example, preferably a linear, branched, or cyclic alcohol (including an ether alcohol) having 1 to 20 carbon atoms. 
     Specifically, examples thereof include methanol, ethanol, n-propanol, isopropanol, polyethylene glycol, propylene glycol, propylene glycol acetate monoester, glycerin, n-butanol, 2-butanol, i-butanol, t-butanol, butane-1,3-diol, diethylene glycol, diethylene glycol monoethyl ether, diethylene glycol monopropyl ether, dipropylene glycol, n-pentanol, 2-pentanol, 3-pentanol, t-amyl alcohol, isoamyl alcohol, 2-methylbutanol, 3-methyl-2-butanol, 3-methyl-2-butenol, 3-methyl-3-butanol, 1-penten-3-ol, n-hexanol, capryl alcohol, 2-ethyl-1-hexanol, decanol, linalol, geraniol, lauryl alcohol, myristyl alcohol, benzyl alcohol, phenylethyl alcohol, cinnamyl alcohol, 3-methoxypropanol, methoxymethoxyethanol, ethylene glycol, ethylene glycol mono-n-butyl ether, diethylene glycol mono-n-butyl ether, triethylene glycol mono-n-butyl ether, tetraethylene glycol mono-n-butyl ether, dipropylene glycol monobutyl ether, citronellol, terpineol, hydroxycitronellal, hydroxycitronellal dimethyl acetal, ethylate glycol monomethyl ether, ethylene glycol monoethyl ether, propylene glycol monomethyl ether, propylene glycol monoethyl ether, diacetone alcohol, ethylene glycol monoisopropyl ether, and diethylene glycol monomethyl ether.

     In order to further reduce the variation in the value of antiviral activity, it is preferable that the solvent contains an alcohol having two or less carbon atoms and an alcohol having three or more carbon atoms. In other words, it is preferable that the solvent contains both the alcohol having two or less carbon atoms and alcohol having three or more carbon atoms. 
     The alcohol having three or more carbon atoms is more soluble in tat than the alcohol having two or less carbon atoms. It is considered that the alcohol having three or more carbon atoms may easily remove viruses and organic substances containing viruses (for example, stains and the like). Therefore, it is considered that in a case where the liquid agent contains both the alcohol having two or less carbon atoms and alcohol having three or more carbon atoms, the variation in the value of antiviral activity may be further reduced. 
     In a case where the alcohol having two or less carbon atoms and the alcohol having three or more carbon atoms are used in combination, the ratio of the mass of the alcohol having three or more carbon atoms to the mass of the alcohol having two or less carbon atoms in the liquid agent (mass of alcohol having three or more carbon atoms/mass of the alcohol having two or less carbon atoms) is preferably 0.01 to 0.9, more preferably 0.03 to 0.5, and even more preferably 0.03 to 0.4.

     The synthetic fiber is not particularly limited, and examples thereof include a vinylon fiber; a vinylidene fiber, a polyester fiber such as a polyethylene terephthalate fiber, polybutylene terephthalate fiber, a polytrimethylene terephthalate fiber, and a copolymerized polyester fiber; a polyolefin fiber such as a polyethylene fiber and a polypropylene fiber; a polyamide fiber such as a nylon 6 fiber, a nylon 66 fiber, a nylon 610 fiber, and a nylon 46 fiber; an acrylic fiber such as a polyacrylonitrile fiber, a polyurethane fiber; a polyvinyl chloride fiber, an aramid fiber; a benzoate fiber; a polychlal fiber; a novoloid fiber, a polyfluoroethylene fiber, and the like. 
     The semi-synthetic fiber is not particularly limited, and examples thereof include an acetate fiber, a triacetate fiber, a promix fiber, and the like. 
     The regenerated fiber is not particularly limited, and examples thereof include a rayon fiber, a polynosic fiber, a cupra fiber, a lyocell fiber, and the like. 
     In view of further improving the storage stability of the wiper, the fibers constituting the base fabric preferably contain a synthetic fiber, and more preferably contain one or more kinds of synthetic fibers selected from the group consisting of a polyolefin fiber (preferably a polyethylene fiber or a polypropylene fiber), a polyester fiber (preferably a polyethylene terephthalate fiber), a vinylon fiber, and a nylon fiber. 
     In the fibers constituting the base fabric, the content of the synthetic fiber with respect to the total mass of the fibers is, for example, equal to or higher than 30% by mass, preferably equal to or higher than 80% by mass, and even more preferably equal to or higher than 95% by mass. The upper limit of the content of the synthetic fiber is, for example, equal to or lower than 100% by mass with respect to the total mass of the fibers. 
     The fibers constituting the base fabric are preferably synthetic fibers selected from the group consisting of a polyolefin fiber (preferably a polyethylene fiber or a polypropylene fiber), a polyester fiber (preferably a polyethylene teraphthalate fiber), and a vinylon fiber, and more preferably synthetic fibers selected from the group consisting of a polyolefin fiber (preferably a polyethylene fiber or a polypropylene fiber) and a polyester fiber (preferably a polyethylene terephthalate fiber). 
     In the fibers constituting the base fabric, the content of the cellulosic fiber (total content in a case where the base fabric contains two or more kinds of cellulosic fibers) with respect to the total mass of the fibers is preferably equal to or lower than 70% by mass. In view of further improving the storage stability of the wiper, the content of the cellulosic fiber is preferably equal to or lower than 30% by mass. Particularly, in view of further improving the storage stability of the wiper, it is more preferable that the fibers constituting the base fabric substantially do not contain the cellulosic fiber. Herein, “substantially do not contain” means that the content of the cellulosic fiber with respect to the total mass of the fibers is equal to or lower than 5% by mass. The content of the cellulosic fiber is more preferably equal to or lower than 3% by mass, and even more preferably equal to or lower than 1% by mass. The lower limit is not particularly limited, but is 0% by mass for example. 
     The cellulosic fiber means a cellulose-containing fiber or a fiber derived from cellulose. Specific examples of the cellulosic fiber include a pulp fiber, a rayon fiber, a polynosic fiber, a cupra fiber, a lyocell fiber, an acetate fiber, a diacetate fiber, a triacetate fiber, a cotton fiber, a linen fiber, and the like. 
     The type of the base fabric is not particularly limited, and examples thereof include a woven fabric, a non-woven fabric, a knit fabric, and the like. Among these, a non-woven fabric is preferable. 
     The basis weight (mass per unit area) of the base fabric is preferably equal to or lower than 100 g/m 2 . In a case where the base fabric is impregnated with the liquid agent, the amount of the liquid agent is preferably equal to or larger than the amount of the base fabric in terms of mass. 
     [Wiper Manufacturing Method] 
     The method of impregnating the base fabric with the liquid agent is not particularly limited. For example, a method may be used in which a base fabric wound in the form of a roll is put in a bottle container so that the roll surface comes into contact with the bottom portion of the bottle container, and the liquid agent is dropped to the upper roll surface of the base fabric wound in the form of a roll so that the base fabric is impregnated with the liquid agent. 
     [Use of Wiper] 
     The use of the wiper is not particularly limited. 
     The wiper acts to inactivate viruses belonging to the family Caliciviridae, the family Orthomyxoviridae, the family Coronaviridae, the family Herpesviridae, and the like. Therefore, it is preferable to use the wiper for reducing the activity of the above viruses by causing the wiper to act on the viruses. Examples of viruses belonging to the family Caliciviridae include viruses belonging to the genus  Norovirus , the genus  Sapovirus , the genus  Lagovirus , the genus  Nebovirus , the genus  Vesivirus , and the like. The wiper exerts an excellent inactivating effect on the viruses belonging to the genus  Norovirus  and the viruses belonging to the genus  Vesivirus  among the above viruses. That is, the wiper is preferably used as an anti-norovirus wiper, that is, a wiper for reducing the activity of noroviruses by acting on the noroviruses. 
     In addition, the wiper may be used as an antibacterial wiper against microorganisms such as bacteria and fungi (for example,  Escherichia coli, Staphylococcus, Trichophyton, Candida Albicans, Aspergillus , and the like). 
     Examples 
     Hereinafter, the present invention will be more specifically described based on examples. The materials, amounts and proportions of the materials used, details and procedures of treatments, and the like described in the following examples can be appropriately changed as long as the gist of the present invention is maintained. Therefore, the scope of the present invention is not limited to the following specific examples. 
     By using a liquid agent prepared by the following method, a wiper was prepared, and the antiviral activity of the wiper was evaluated. Feline calicivirus was used for the evaluation of antiviral activity. Feline calicivirus is widely known to be used to demonstrate the inactivation action of drugs on norovirus. 
     Preparation of Wiper of Example 1 
     [Liquid Agent Preparation Method] 
     Alcohols (73 g of ethanol and 3 g of isopropanol) were added to a glass container containing 4-hydroxy-benzoic acid (corresponding to the compound X (compound having a phenolic hydroxyl group)) and disodium ethylenediaminetetraacetate (corresponding to a chelating agent), and the 4-hydroxy-benzoic acid and the disodium ethylenediaminetetraacetate were dissolved in the alcohols. Then, water and a 1 mol/L aqueous sodium hydroxide solution were added to the glass container so that the total amount of water was 24 g and the pH of the prepared liquid agent was 11.5, thereby obtaining a liquid agent used in Example 1 containing components mixed together in the amount described in Table 1. 
     The pH was measured by the following method. 
     &lt;Measurement of pH of Liquid Agent&gt; 
     pH calibration was performed using a pH standard solution, and then the pH was measured using a pH meter (trade name “pH-water quality analyzer LAQUA F-72S”, manufactured by HORIBA, Ltd.) and a pH electrode (trade name “6377-10D”, manufactured by HORIBA, Ltd.). A sample solution was prepared at a solution temperature of 25° C., the electrode was then immersed in the sample solution and left to stand for about 1 to 2 minutes, and a pH value remain stable on the pH meter was read. The results are shown in Table 1. 
     [Preparation of Wiper] 
     A wiper was prepared using the above liquid agent. Specifically, a non-woven fabric composed of 50% by mass of a rayon fiber, 30% by mass of a polyethylene terephthalate (PET) fiber, and 20% by mass of a polyolefin fiber (mixed fiber of a PP fiber and a PE fiber) was impregnated with the liquid agent having mass 400% of the mass of the non-woven fabric, thereby obtaining a wiper of Example 1. 
     Furthermore, a wiper for preparing a control sample of Example 1 was obtained by the same method except that sterile purified water was used instead of the above liquid agent. 
     [Various Evaluations] 
     &lt;Evaluation of Antiviral Activity of Wiper Immediately after Preparation&gt; 
     Immediately after being prepared, the wiper of Example 1 was used for a wiping test with reference to “Method for testing antibacterial effect of wet wipes (revised on Nov. 16, 2015)” established by the Japan Hygiene products Industry Association. 
     Specifically, the test protocol is as follows. Based on “Method for testing antibacterial effect of wet wipes (revised on Nov. 16, 2015)” established by the Japan Hygiene products Industry Association, a test carrier (stainless steel plate) was inoculated with a viral solution obtained by culturing feline calicivirus (ATCC VR-782) in a Minimum Essential Media (MEM) and dried. Then, the carrier was wiped with a weight wrapped with the wiper of Example 1. Thereafter, the test carrier was put in 20 mL of an SCDLP medium, and the residual virus was washed off the test carrier, thereby obtaining a viral solution for preparing a sample. In addition, a viral solution for preparing a control sample was obtained in the same manner as described above, except that the wiper for preparing a control sample of Example 1 was used instead of the wiper of Example 1. Subsequently, CRFK cells cultured on an agar medium were inoculated with 0.1 mL of the viral solution for preparing a sample, and the solution was left to be adsorbed onto the cells at 37° C. for 1 hour. Then, the test solution on the CRFK cells was drained, agar media were layered, and the cells were cultured for 2 to 3 days. After culturing, the number of plaques formed on the agar medium was counted, and the infectious titer was calculated and adopted as “infectious titer of a wiper”. Furthermore, the infectious titer was also calculated for a sample prepared in the same manner as described above except that the viral solution for preparing a control sample was used instead of the viral solution for preparing a sample, and the calculated titer was adopted as “infectious titer of a control wiper”. The results are shown in Table 1. 
       Value of antiviral activity= A−B   Equation 2
 
     A in the above equation represents a common logarithm of the infectious titer of a control wiper. 
     B in the above equation represents a common logarithm of the infectious titer of a wiper. 
     (Evaluation Standard) 
     “AA”: The value of antiviral activity is equal to or higher than 4.0. 
     “A”: The value of antiviral activity is equal to or higher than 3.5 and less than 4.0. 
     “B”: The value of antiviral activity is equal to or higher than 3.0 and less than 3.3. 
     “C”: The value of antiviral activity is equal to or higher than 2.5 and less than 3.0. 
     “D”: The value of antiviral activity is less than 2.5. 
     &lt;Evaluation of Wiper after 6 Months of Storage&gt; 
     Immediately after being prepared, the wiper of Example 1 and the wiper for preparing a control sample of Example 1 were put in different airtight containers and stored for 6 months in a dark place. 
     (Quantification of Content of Active Components and pH Evaluation) 
     The liquid was squeezed from the wiper of Example 1 after the 6 months of storage, and the content of the active component in the liquid (content of the active component with respect to the total mass of the liquid (% by mass)) was quantified by high performance liquid chromatography (HPLC). In addition, the pH of the above liquid was measured by the method described above. The results are shown in Table 1. “Active component” mentioned herein means the compound having a phenolic hydroxyl group (including a phenoxide anion derivative formed by the dissociation of a hydroxyl group of the phenolic hydroxyl group). 
     (Evaluation of Antiviral Activity of Wiper after 6 Months of Storage) 
     By using the wiper of Example 1 and the wiper for preparing a control sample of Example 1 after 6 months of storage, the antiviral activity was evaluated by the same method as that in &lt;Evaluation of antiviral activity of wiper immediately after preparation&gt; described above. The results are shown in Table 1. 
     Preparation of wipers of Examples 2 to 22 and Comparative Examples 1 to 3 
     Wipers were prepared by the same method as that in Example 1 according to the composition and mixing ratio shown in Table 1, and evaluated in the same manner as in Example 1. 
     Table 1 is shown below. 
     The abbreviations used in Table 1 stand for the following.

In Table 1, one of the pKa values within a range of 7.0 to 15.0 is listed. In Table 1, the pKa values in Examples 2 to 9, Examples 11 to 22, and Comparative Examples 1 to 3 correspond to pKa obtained in a case where a hydrogen atom is dissociated from a phenolic hydroxyl group in the compound X which is an active component. Furthermore, the pKa value in Example 10 corresponds to pKa obtained in a case where a hydrogen atom is dissociated from a mercapto group in the compound X which is an active component.

     From the results in Table 1, it has been revealed that the wipers of examples have excellent antiviral activity and excellent storage stability. 
     Furthermore, from the comparison of Examples 4 to 12, it has been confirmed that in a case where the compound X which is an active component is a compound having a phenolic hydroxyl group, the antiviral properties are further improved. 
     In addition, from the comparison of Examples 1 to 3 and Examples 12 to 14, it has been confirmed that in a case where the content of the cellulosic fiber is equal to or lower than 30% by mass with respect to the total mass of fibers (preferably in a case where the fibers substantially do not contain the cellulosic fiber), the storage stability is further improved. 
     Furthermore, from the comparison of Examples 12 to IS and Example 16, it has been confirmed that in a case where the fibers constituting the base fabric are synthetic fibers selected from the group consisting of a polyolefin fiber, a polyester fiber, and a vinylon fiber, the storage stability is further improved. Particularly, from the comparison of Examples 12 to 14 and Example 15, it has been confirmed that in a case where the fibers constituting the base fabric are synthetic fibers selected from the group consisting of a polyolefin fiber and a polyester fiber, the pH of the liquid agent in the wiper is hardly reduced, and the storage stability is further improved. 
     From the comparison between Example 20 and Example 22, it has been confirmed that in a case where the liquid agent contains a chelating agent, the antiviral activity of the wiper is further improved. 
     From the comparison between Example 13 and Example 19, it has been confirmed that in a case where the liquid agent contains a surfactant, the antiviral activity of the wiper is further improved. 
     From the comparison of Example 12, Example 20, and Example 21, it has been confirmed that in a case where the liquid agent contains an alcohol having two or less carbon atoms and an alcohol having three or more carbon atoms, the antiviral activity of the wiper is further improved. In addition, from the comparison between Example 12 and Example 20, it has been confirmed that in a case where the content of an alcohol in the liquid agent is equal to or higher than 60% by mass with respect to the total mass of the solvent, the antiviral activity of the wiper is further improved.
