Summary of the Invention

Problems to be Solved by the Invention

[0004] When using Actinidia polygama in cat-related products, it is necessary to have a good attracting effect without the cat ingesting Actinidia polygama excessively. However, when using the powder of Actinidia polygama as in the above prior art, it is not easy to uniformly apply an appropriate amount. Further, in cat-related products using such Actinidia polygama, an improvement in the persistence of the inducing effect on cats is required.

[0005] The present invention has been made based on the above circumstances, and an object thereof is to provide a paper coated with an extract of Actinidia polygama components that has a good attracting effect on cats and is excellent in the persistence of the attracting effect.

Means for Solving the Problems

[0006] The Actinidia polygama component extract-coated paper according to one aspect of the present invention includes a base material and a coating layer laminated on the surface of the base material, and the basis weight of the base material is 40 g / m 2 or more and 400 g / m 2 or less, the air permeability resistance of the base material is 20 seconds / 100 cm 3 or more and 200 seconds / 100 cm 3 or less, the coating layer contains an Actinidia polygama component extract, and the content of the Actinidia polygama component extract per side of the coating layer is 0.005 g / m 2 or more and 0.100 g / m 2 or less, and the coating layer does not contain a water-repellent varnish and a binder.

Advantages of the Invention

[0007] According to the present invention, it is possible to provide an Actinidia polygama component extract-coated paper that has a good attracting effect on cats and is excellent in the persistence of the attracting effect.

Modes for Carrying Out the Invention

[0008] [Description of Embodiments of the Present Invention] The Actinidia polygama component extract-coated paper according to one aspect of the present invention includes a base material and a coating layer laminated on the surface of the base material, and the basis weight of the base material is 40 g / m 2 or more and 400 g / m 2 or less, the air permeability resistance of the base material is 20 seconds / 100 cm 3 or more and 200 seconds / 100 cm 3 or less, the coating layer contains an Actinidia polygama component extract, and the content of the Actinidia polygama component extract per side of the coating layer is 0.005 g / m 2 or more and 0.100 g / m 2 or less, and the coating layer does not contain a water-repellent varnish and a binder.

[0009] The Actinidia polygama component extract-coated paper has a basis weight of the base material of 40 g / m 2 or more and 400 g / m 2The following conditions ensure that the penetration depth of the catnip extract is within a suitable range, thereby achieving both an attractive effect on cats and a sustained attractive effect: The air permeability resistance of the above substrate is 20 seconds / 100 cm. 3 More than 200 seconds / 100cm 3 The following conditions allow the coating solution containing the silver vine extract applied to form the coating layer to remain on the surface of the substrate, thereby improving the persistence of the attractive effect on cats. Furthermore, the above coating layer on one side contains the silver vine extract, and the amount of the silver vine extract on one side of the above coating layer is 0.005 g / m² in terms of solid content. 2 More than 0.100g / m 2 The following conditions ensure a good attractant effect on cats. Furthermore, by not containing water-repellent varnish and binder in the coating layer, the decrease in the volatility of the silver vine components can be suppressed. Therefore, the silver vine component extract coated paper has a good attractant effect on cats and excellent durability of that attractant effect.

[0010] "Air permeability resistance" can be measured by the Gurley method in accordance with "Paper and cardboard - Test method for air permeability and air permeability resistance (intermediate range)" described in JIS-P8117 (2009). "Matatabi" is a general term for plants of the genus Actinidiaceae. "Matatabi component extract" is a liquid from which components of matatabi have been extracted, and contains aromatic components such as nepetalactol that induce a matatabi reaction in cats. "Matatabi reaction" refers to the behavior of rubbing aromatic components such as nepetalactol on the face and body to repel mosquitoes.

[0011] It is preferable that the surface smoothness of the substrate in the silver vine extract coated paper is between 0.5 seconds and 5.0 seconds. By having a surface smoothness of 0.5 seconds and 5.0 seconds, the silver vine extract coated paper has a surface with appropriate flatness, which allows for a better balance between a good attraction effect on cats and the persistence of that attraction effect. The surface smoothness of the substrate is measured in seconds according to the smoothness test method using a paper and cardboard Beck smoothness tester as specified in JIS-P8119 (1998).

[0012] It is preferable that the content of water-soluble chloride in the matatabi extract-coated paper is between 12 mg / kg and 300 mg / kg. A water-soluble chloride content of 12 mg / kg or more and 300 mg / kg or less in the matatabi extract-coated paper ensures that the coating layer is uniformly laminated, thereby further improving the persistence of the attractant effect. The above-mentioned "water-soluble chloride content" is a value measured in accordance with the measurement method for water-soluble chloride in paper, cardboard, and pulp described in JIS-P8144 (2006). The water-soluble chloride content in the matatabi extract-coated paper can be arbitrarily adjusted, for example, by washing the raw pulp with chlorine-free water such as pure water, or by adding sodium hypochlorite as a disinfectant to the dilution water of the coating solution. For example, tap water and industrial water may contain sodium hypochlorite as a disinfectant, so by checking its concentration and keeping the water-soluble chloride content in the matatabi extract-coated paper within the above range, it is possible to achieve both productivity (bacterial count control in the manufacturing process) and quality (attractant effect and its persistence).

[0013] [Details of the Embodiments of the Invention] The present invention will be described in detail below. The following descriptions of constituent elements may be based on representative embodiments or specific examples, but the present invention is not limited to such embodiments.

[0014] <Paper coated with silver vine extract> The matatabi component extract coated paper comprises a base material and a coating layer laminated on the surface of the base material.

[0015] The lower limit of the water-soluble chloride content in the matatabi extract-coated paper is preferably 12 mg / kg, and more preferably 14 mg / kg. The upper limit of the water-soluble chloride content in the matatabi extract-coated paper is preferably 300 mg / kg, and more preferably 250 mg / kg. By having a water-soluble chloride content of 12 mg / kg or more and 300 mg / kg or less in the matatabi extract-coated paper, the coating layer of the matatabi extract-coated paper is uniformly laminated, which can further improve the persistence of the attractant effect.

[0016] The lower limit of the content of the silver vine component in the silver vine component extract coated paper is 0.005 g / m². 2 Preferably, 0.010 g / m 2 This is more preferable. On the other hand, the upper limit for the content of the silver vine component in the silver vine component extract coated paper is 0.100 g / m². 2 Preferably, the content of the silver vine component in the silver vine component extract coated paper is 0.005 g / m². 2 If the amount is less than 0.100 g / m², there is a risk that the attractive effect on cats will not be sufficiently obtained. On the other hand, the content of the silver vine component in the silver vine component extract coated paper is 0.100 g / m². 2 The effect tends to plateau at that point.

[0017] [Base material] The above-mentioned base material mainly consists of wood pulp fibers and is a layer obtained by papermaking using pulp fibers. Examples of base materials include paper (for example, cardboard, printing paper, packaging paper, and synthetic paper). The base material may be a single layer or multiple layers. The base material is particularly preferable to be a corrugated cardboard liner from the viewpoint of strength and ease of processing. The above-mentioned pulp fibers are not particularly limited, and for example, chemical pulp, recycled paper pulp, mechanical pulp, etc. can be used.

[0018] Examples of chemical pulps include wood pulps such as bleached hardwood kraft pulp (LBKP), bleached softwood kraft pulp (NBKP), unbleached hardwood kraft pulp (LUKP), unbleached softwood kraft pulp (NUKP), semi-bleached hardwood kraft pulp (LSBKP), semi-bleached softwood kraft pulp (NSBKP), hardwood sulfite pulp, and bleached softwood sulfite pulp (NBSP).

[0019] Examples of recycled paper pulp include disintegrated recycled paper pulp, disintegrated and deinked recycled paper pulp, and deinked and bleached recycled paper pulp, which are manufactured from recycled corrugated cardboard, brown recycled paper, kraft envelope recycled paper, magazine recycled paper, newspaper recycled paper, flyer recycled paper, office recycled paper, white recycled paper, Kent recycled paper, structural recycled paper, and land deed recycled paper recycled paper.

[0020] Examples of mechanical pulps include stone gland pulp (SGP), pressure stone gland pulp (PGW), refiner gland pulp (RGP), chemigland pulp (CGP), thermo gland pulp (TGP), gland pulp (GP), thermomechanical pulp (TMP), chemothermetic pulp (CTMP), and refiner mechanical pulp (RMP).

[0021] Furthermore, these wood pulps can be used as the main material, and non-wood pulps such as hemp, cotton, straw, and kenaf, as well as synthetic pulps made from polyethylene, polypropylene, polyacrylonitrile, etc., can be used in combination. In addition, organic synthetic fibers such as acrylic fibers, rayon fibers, polyester fibers, and polyamide fibers, as well as inorganic fibers such as glass fibers, carbon fibers, alumina fibers, silica-alumina silicate fibers, and rock wool, can also be used in combination.

[0022] The above-mentioned substrate may contain a paper strength enhancer and a sizing agent. Other components that may be included in the above-mentioned substrate include, for example, sizing agents, paper strength enhancers, dyes, pigments, yield enhancers, fillers, pH adjusters, slime control agents, viscosity modifiers, preservatives, fungicides, flame retardants, etc. These can be used individually or in combination of two or more.

[0023] (Basic weight) The basis weight of the above-mentioned substrate is 40 g / m². 2 More than 400g / m 2 The following applies: 100g / m 2 More than 200g / m 2 The following is preferable: By setting the basis weight of the above-mentioned substrate within the above range, the penetration depth of the silver vine extract will be within a suitable range, resulting in a balance between attracting cats and the persistence of that attracting effect.

[0024] (Air permeability resistance) The lower limit of the air permeability resistance of the above substrate is 20 seconds / 100 cm. 3 And, 30 seconds / 100cm 3 This is preferable. On the other hand, the upper limit of the air permeability resistance of the above substrate is 200 seconds / 100 cm. 3 And, 150 seconds / 100cm 3 Preferably, the air permeability resistance of the above substrate is 20 seconds / 100 cm. 3 If the value is less than 200 seconds / 100cm, the coating liquid containing the silver vine extract applied to form the coating layer may penetrate too deeply into the substrate, potentially resulting in insufficient attraction to cats. 3 If the pressure exceeds a certain level, the adhesion between the coating layer and the substrate may decrease, potentially reducing the duration of the attractive effect on cats. The air permeability resistance can be adjusted by changing the average thickness and density of the substrate using the press line pressure.

[0025] (Smoothness) The lower limit of the smoothness of the substrate surface is preferably 0.5 seconds, and more preferably 0.8 seconds. On the other hand, the upper limit of the smoothness of the substrate surface is preferably 5.0 seconds. By having a substrate surface smoothness of 0.5 seconds or more and 5.0 seconds or less, the matatabi component extract coated paper has a substrate surface with appropriate flatness, thus achieving a better balance between a good attraction effect on cats and the persistence of that attraction effect. The smoothness of the substrate can be adjusted by the linear pressure of the on-machine calender during the finishing process after the coating process of the coating liquid.

[0026] (density) The density of the substrate is measured in accordance with "Paper and cardboard - Test methods for thickness, density and specific volume" as described in JIS-P8118(2014). The lower limit of the substrate density is 0.50 g / cm³. 3 Preferably, 0.60 g / cm³ 3 This is more preferable. The upper limit for the density of the base material is 0.90 g / cm³. 3 Preferably, 0.80 g / cm³ 3 A density of 0.50 g / cm³ of the above substrate is more preferable. 3 If the density is less than 0.90 g / cm³, the coating solution containing the silver vine extract applied to form the coating layer may penetrate the substrate too much, potentially resulting in insufficient attraction to cats. 3 If the density exceeds a certain level, the penetration of the coating solution containing the above-mentioned silver vine extract into the substrate may be low, potentially reducing the duration of its attractive effect on cats. The density is measured under an atmosphere of 23±1℃ and 50±2%RH, as described in JIS-P8111 (1998) "Paper, cardboard and pulp - Standard conditions for humidity control and testing".

[0027] (Average thickness of the base material) The average thickness of the substrate is measured in accordance with "Paper and cardboard - Test methods for thickness and density" described in JIS-P8118 (2014). The lower limit of the average thickness of the substrate is preferably 122 μm, and more preferably 140 μm. The upper limit of the average thickness of the substrate is preferably 220 μm, and more preferably 185 μm. If the average thickness of the substrate is less than 122 μm, the penetration of the silver vine extract applied to form the coating layer into the substrate may be low, which may reduce the persistence of the attractive effect on cats. If the average thickness of the substrate exceeds the air permeability resistance of the substrate of 220 μm, the coating liquid containing the silver vine extract may penetrate the substrate too much, which may result in an insufficient attractive effect on cats. "Average thickness of the substrate" means the average value of the average thickness of the substrate at any 20 points.

[0028] (Hump size) The Cobb size degree is measured according to the Cobb method for water absorption test described in JIS-P8140 (1998) for paper and cardboard, with a measurement time of 10 seconds. The lower limit for the Cobb size degree of the substrate is 150 g / m². 2 This is preferable. On the other hand, the upper limit for the degree of bump size of the base material is 300 g / m². 2 This is preferable. When the degree of bump size of the substrate at a measurement time of 10 seconds is within the above range, the penetration of the coating liquid containing the above silver vine extract into the substrate is within a good range, thus achieving both an attractive effect on cats and the persistence of that attractive effect. The degree of bump size can be adjusted by basis weight, type of sizing agent, amount added, and ash content of the substrate. From the viewpoint of adjusting the degree of bump size, the amount of sizing agent added is preferably 0.01% by mass or more and 2.0% by mass or less in terms of solid content, and the ash content is preferably 5.0% or more and 20.0% or less. The above ash content is a value measured in accordance with JIS-P8251 (2003).

[0029] (Oil absorption) "Oil absorption" is a value measured using light oil in accordance with JIS-P8130 (1994). The lower limit of the oil absorption of the above substrate is preferably 10 seconds. On the other hand, the upper limit of the bump size of the substrate is preferably 100 seconds. When the oil absorption of the above substrate is within the above range, the penetration of the coating liquid containing the above silver vine component extract into the substrate is within a good range, so that both the attractive effect on cats and the persistence of the attractive effect can be achieved. The above oil absorption can be adjusted by density, type of sizing agent, amount added, and ash content of the substrate. From the viewpoint of adjusting the oil absorption, the amount of sizing agent added is preferably 0.01% by mass or more and 2.0% by mass or less in terms of solid content, and the ash content is preferably 5.0% or more and 20.0% or less.

[0030] [Coating layer] The coating layer contains an extract of the silver vine (Actinidia polygama).

[0031] (Actinidia polygama extract) The silver vine extract used in this invention is a liquid from which components of silver vine have been extracted, and contains nepetalactol, which induces a silver vine reaction in cats.

[0032] The coating solution for forming the above-mentioned coating layer contains a solvent and an extract of the Actinidia polygama component. As the Actinidia polygama component extract, for example, a solution containing 10% to 30% by mass of the Actinidia polygama component, using alcohol and water as the solvent, can be used.

[0033] As the solvent, pure water is preferred.

[0034] In addition to the solvent and silver vine extract, the above coating solution may contain, as needed, fragrances, antibacterial agents, antiviral agents, antifungal agents, deodorants, and the like.

[0035] The above coating layer does not contain a water-repellent varnish or binder. If the above coating layer contains a water-repellent varnish or binder, the volatility of the silver vine component will decrease, which may result in insufficient attraction of cats to the silver vine component extract coated paper and insufficient persistence of that attraction effect.

[0036] The lower limit for the amount of coating (in terms of solid content) of the above coating layer is 0.005 g / m². 2 Preferably, 0.010 g / m 2 This is more preferable. On the other hand, the upper limit for the amount of the above coating layer applied (in terms of solid content) is 0.100 g / m². 2 Preferably, 0.080 g / m 2 This is more preferable. If the amount of the coating layer is less than the lower limit, a good attraction effect on cats may not be obtained. On the other hand, if the amount of the coating layer exceeds the upper limit, the processing suitability of the catnip extract coated paper may decrease.

[0037] Furthermore, when coating layers are laminated on both sides of the above-mentioned substrate, the composition and content of each coating layer, the amount of coating, etc., can be configured as described above.

[0038] [Method for manufacturing paper coated with silver vine extract] The method for manufacturing the matatabi component extract coated paper comprises the step of laminating a coating layer consisting of a coating liquid containing matatabi component extract onto the surface of a substrate. The method for manufacturing the matatabi component extract coated paper may also comprise the step of papermaking a pulp slurry that will be the raw material for the substrate. In the papermaking step, the raw material slurry containing the aforementioned raw material pulp, oil resistant agent, and other additives is processed using a known papermaking machine. Furthermore, the method for manufacturing the matatabi component extract coated paper may also comprise the step of forming a printed layer on the surface of the substrate by offset printing, gravure printing, flexographic printing, inkjet printing, or the like.

[0039] [Coating layer lamination process] This process includes a step of laminating a coating layer onto the surface of a substrate. The coating layer consists of a coating liquid (composition for the coating layer) containing an extract of the silver vine component. The coating layer can be laminated by, for example, flexographic printing, offset printing, or gravure printing. Among these, lamination by flexographic printing is preferred. By laminating the coating layer by flexographic printing, a coating layer consisting of a raised halftone pattern can be formed. As a result, the coating layer can be formed uniformly, and its thickness and specific surface area can be increased, thereby further improving the attractive effect on cats and the persistence of that attractive effect in the silver vine component extract coated paper.

[0040] Details of the coating solution containing the above-mentioned silver vine extract are as described above, so we will omit further explanation.

[0041] Flexographic printing is a relief printing method that uses a flexographic printing press equipped with a relief plate roll made of rubber or resin, an anilox roll with fine cells engraved in parallel on its surface, and an impression cylinder roll that applies low pressure when transferring from the relief plate roll to the substrate. First, the coating liquid, which is an aqueous ink, is supplied to the anilox roll from a fountain roll (rubber roll) or doctor chamber. The temperature of the supplied coating liquid is adjusted by a heating tank according to the ambient temperature. Next, the anilox roll transfers a fixed amount of the coating liquid to the relief plate roll. Then, a coating layer is deposited on the surface of the substrate as it passes between the relief plate roll and the impression cylinder roll.

[0042] The lower limit of the line screen count for the anilox roll of the flexographic printing press used in the flexographic printing method in the above coating layer lamination process is preferably 120 lines / inch, and more preferably 165 lines / inch. On the other hand, the upper limit of the line screen count is not particularly limited, but is preferably 500 lines / inch, and more preferably 200 lines / inch. By setting the line screen count engraved on the cylindrical surface of the anilox roll of the flexographic printing press within the above range, the thickness of the coating layer of the manufactured silver vine extract coated paper is improved, thereby further improving the durability of the coating layer. If the line screen count is below the lower limit, there is a risk that a sufficient attractive effect on cats will not be obtained. On the other hand, if the line screen count exceeds the upper limit, there is a risk of transfer defects (uneven coating).

[0043] In the method for manufacturing the matatabi component extract coated paper, the coating liquid for the coating layer may be applied multiple times. Furthermore, since the coating layer is laminated by a flexographic printing method, a coating layer consisting of a raised halftone pattern can be formed. As a result, a uniform coating layer can be formed, and the thickness and specific surface area can be increased, thus forming a coating layer with excellent abrasion resistance and durability.

[0044] This catnip extract-coated paper has a good attractant effect on cats and exhibits excellent persistence of that effect.

[0045] <Other Embodiments> The present invention is not limited to the embodiments described above, and can be implemented in various modified and improved forms in addition to those described above. [Examples]

[0046] The present invention will be described in more detail below with reference to examples, but the present invention is not limited to the following examples.

[0047] [Examples 1-13] (base material) A pulp slurry consisting of 100% by mass of recycled corrugated cardboard pulp was used to produce a paper pulp slurry to which a paper strength enhancer and an internal sizing agent were added. This slurry was then used in papermaking to obtain a base material (liner paper for corrugated cardboard) having the basis weights listed in Table 1.

[0048] (Coating layer) (1) Preparation of coating solution The coating solutions for Examples 1 to 13 were prepared using the silver vine component extracts and pure water as diluents, with the content ratios listed in Table 1. The compositions of the silver vine component extracts used in the coating solutions for Examples 1 to 13 are also shown in Table 1. (2) Flexographic printing A coating layer was formed on the substrate using a flexographic printing machine, with the coating liquid applied in the amount shown in Table 2 in terms of solid content. The conditions for flexographic printing are as follows. The number of coating coats is shown in Table 2. Coating solution supply: Doctor chamber system Coating solution temperature: 20℃~25℃ Printing speed: 150m / min Anilox roll line count: 200 lines / inch

[0049] [Comparative Example 1 to Comparative Example 6] The coating solutions for Comparative Examples 1 to 6 were prepared using the same Actinidia polygama extract as in Example 1. The mass ratio of Actinidia polygama extract to dilution water in the coating solutions for Comparative Examples 1 to 6 is shown in Table 1 below. Then, the coating layers were formed using a flexographic printing press under the same conditions as in Example 1.

[0050] [Reference Examples 1 and 2] Using the same substrate as in Example 1, coated paper of Reference Example 1 was prepared by a conventional manufacturing method in which silver vine powder is sprinkled onto paper. Also using the same substrate as in Example 1, coated paper of Reference Example 2 was prepared by laminating coating layers with a coating solution diluted with water-repellent varnish instead of pure water, as shown in Table 1.

[0051] Table 1 shows the measurement results of the physical properties of the substrate, as well as the compositions of the silver vine extract and coating solution.

[0052] [Table 1]

[0053] [evaluation] The matatabi component extract coated papers of Examples 1 to 13, Comparative Examples 1 to 6, Reference Example 1 and Reference Example 2 were evaluated using the following method.

[0054] (Evaluation of the duration of the attractive effect of silver vine extract) Paper coated with an extract of Actinidia polygama (silver vine) was heated in a constant-temperature dryer at 180°C for 20 seconds. Then, samples were prepared that were irradiated for 2 hours and 8 hours using a fade meter (Suga Test Co., Ltd., model U48AUB) for accelerated testing, as well as unirradiated samples. Note that 2 hours of irradiation with the fade meter corresponds to the degradation state after 6 months, and 8 hours of irradiation corresponds to the degradation state after 24 months. Next, ten cats that react to catnip were prepared in advance, and the catnip extract-coated paper, prepared as described above, was placed approximately 50 cm away from the cats. The number of cats that rubbed against the catnip extract-coated paper within 5 minutes was evaluated as a percentage, and this was used to evaluate the persistence of the catnip. For samples without accelerated testing, a cat attraction rate of 60% or higher indicates a high cat attraction effect and is suitable for practical use. For samples exposed to 8 hours of irradiation, a cat attraction rate of 30% or higher indicates excellent persistence and is suitable for practical use.

[0055] Coating process conditions, content of silver vine extract per side of the coating layer (g / m²) 2Table 2 shows the content of ) and chloride ions (mg / kg), as well as the results of the sustainability evaluation.

[0056] [Table 2]

[0057] As shown in Table 2, the basis weight of the substrate is 40 g / m². 2 More than 400g / m 2 Below, the air permeability resistance is 20 seconds / 100cm. 3 More than 200 seconds / 100cm 3 The following is true: the amount of silver vine extract per side of the coating layer is 0.005 g / m² in terms of solid content. 2 More than 0.100g / m 2 Examples 1 to 13, in which the coating layer did not contain a water-repellent varnish and binder, showed good initial attraction to cats and good persistence of the attraction effect.

[0058] On the other hand, the basis weight of the base material is 40 g / m². 2 Comparative Example 1 and the substrate had an air permeability resistance of less than 200 seconds / 100 cm. 3 In Comparative Example 4, which exceeded the specified value, the persistence of the attractive effect decreased significantly as the irradiation time in the accelerated test increased. The basis weight of the substrate was 400 g / m². 2 Comparative Example 2, exceeding the above, had an air permeability resistance of 20 seconds / 100 cm. 3 Comparative Example 3 and the content of Actinidia polygama extract per side of the coating layer were less than 0.005 g / m². 2 Comparative Example 5, which had a lower initial attractiveness to cats, showed a significant decrease in the persistence of its attractiveness as the irradiation time in the accelerated test increased. The amount of silver vine extract per side of the coating layer is 0.100 g / m². 2 In Comparative Example 6, which exceeded the above, the initial attractive effect on cats and the duration of the attractive effect were found when the content of the above-mentioned silver vine extract was 0.100 g / m². 2 The result was the same as in Example 9. Furthermore, Reference Example 1, produced using a conventional manufacturing method of sprinkling catnip powder on paper, showed good initial attraction to cats, but the persistence of the attraction was very poor. In addition, Reference Example 2, in which a coating layer was laminated using a coating solution diluted with water-repellent varnish instead of pure water, also showed poor initial attraction to cats and poor persistence of the attraction.

[0059] The results above demonstrate that the paper coated with the silver vine extract has a good attractive effect on cats and exhibits excellent persistence of that attractive effect.
