Description

[Technical Field]

[0001] The present invention relates to a powder composition. More specifically, the present invention relates to a powder composition, a coating composition, a coating film, and a method for assisting in the search for a search target or the tracking of a tracked target, which enable assistance in the search for a search target or the tracking of a tracked target. [Background technology]

[0002] In the past, it was not easy to search for, find, and protect missing people such as wandering elderly people and lost children. Therefore, techniques have been proposed for efficiently searching for such search targets.

[0003] Japanese Patent Publication No. 2002-106523 (Patent Document 1) proposes a network system for preventing wandering and missing persons, in which a protected person, such as a dementia patient, can wear a lightweight, small, portable wireless communication device without imposing a physical or mental burden, and can freely go out in the neighborhood as he or she wishes on a daily basis, and can only report the protected person's current location to the guardian if the protected person goes out and approaches a place that is deemed to be high risk to the protected person.

[0004] This network system for preventing wandering and missing persons has a portable wireless communication device that can be carried by the protected person and transmits beacon ID information, and a plurality of wireless LAN base stations connected to at least one communication network are scattered in a predetermined area ranging from the protected person's safe area to other dangerous areas, and the wireless LAN base station is provided with a wireless receiver that can transmit the beacon ID information received from the portable wireless communication device and a detection signal including its own gate ID information to at least one specific server via the wireless LAN base station, and a personal information storage device that stores the beacon ID information in association with the contact information of the guardian of the protected person, a gate ID of the wireless receiver, and The system comprises a gate information storage device that stores D information in association with the installation location of the wireless receiver, a tracking information storage device that can store data received from each of the wireless receivers, and a specific server having a guard program that can control the emergency contact software in an integrated manner, the system being connected to at least one of the communication networks and capable of writing data received from each of the wireless receivers to the tracking information storage device, and capable of automatically making a judgment by referring to at least one of the received data, the records of the tracking information storage device and the records of the gate information storage device based on the criteria for determining the safe area and the dangerous area that have been set in advance for each protected person.

[0005] Japanese Patent Publication No. 2017-111506 (Patent Document 2) proposes a monitoring system that makes it easier to search for the person being monitored who goes out and goes missing while the monitor is not looking, thereby reducing the burden on the monitor of watching over elderly people and children.

[0006] This monitoring system consists of a camera with facial recognition functionality, an information processing device in which the email address of the watcher's communication terminal is registered; Equipped with the camera and the information processing device are each connected to the Internet; The camera registers the face recognition data of the person being monitored, When the camera detects a person being watched in the captured image, it records a video for a certain period of time and transmits the video to the information processing device via the Internet. The information processing device stores the video received from the camera in a memory unit, generates a URL (Uniform Resource Locator) for accessing the video in the memory unit from the Internet, and sends an email containing the URL to the email address registered in the information processing device in association with the camera. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] JP 2017-126967 A (Claims, Figure 1) [Patent Document 2] JP 2017-111506 A (Claims, Figure 1) Summary of the Invention [Problem to be solved by the invention]

[0008] In the network system for preventing wandering and missing persons disclosed in Patent Document 1, the protected person, i.e., the person being searched for, must carry a portable wireless communication device that transmits beacon ID information, and further, multiple wireless LAN base stations must be scattered over a wide area, such as the protected person's safety area.

[0009] In the monitoring system disclosed in Patent Document 2, facial recognition data of the person being monitored is registered in all cameras equipped with a facial recognition function, and the person being monitored is detected. Therefore, in order to enable the search for the person being monitored, it is necessary to install many cameras. Furthermore, if a large number of cameras are installed, the facial recognition data of the person being monitored must be transmitted to many cameras, which may increase the load on the information processing device and the network, and may reduce the efficiency of the search for the person being monitored.

[0023] The powder composition of the present invention contains porous particles, preferably porous silica microparticles, and a fragrance component, wherein the porous particles have, as primary particles, one or more macropores and one or more pores smaller than the macropores, and the fragrance component is a substance having a boiling point of 150°C or higher and being liquid at a temperature between 10°C and 30°C, preferably selected from capric acid, palmitic acid, amyl methyl ketone, and diethyl succinate. Therefore, the powder composition makes it possible to track or assist in tracking the scent or odor of the fragrance contained therein using a predetermined discrimination or identification means such as a device or animal such as a dog that can distinguish or identify the scent or odor. Therefore, the powder composition is placed in a container or the like and placed on the target (a potential target for search or tracking) in advance, and the scent or odor of the fragrance contained in the powder composition is tracked using a device or animal such as a dog that can distinguish or identify the scent or odor, thereby making it possible to search for the search target or track the track target, or to assist in the search or tracking of the tracked target. That is, the powder composition is suitable as a powder composition for assisting in searching for a search target or tracking a tracking target.

[0024] Furthermore, the powder composition can be configured so that the flavor component is present (preferably encapsulated) inside the macropores. In this case, the macropores and the pores smaller than the macropores can be configured to penetrate each other. With this configuration, it becomes possible for the flavor component present inside the macropores to be released to the outside through pores (through holes) that are smaller than the macropores.

[0025] The powder composition can be produced by a production method including a step of immersing the porous particles in a solution containing the fragrance component under reduced pressure and impregnating the particles with the fragrance component, thereby causing the porous particles to carry the fragrance component. According to this method, the powder composition in which the flavor component is encapsulated inside the macropores can be easily produced.

[0026] A coating composition can be prepared by incorporating the powder composition with a solvent and / or a synthetic resin emulsion, in which the solvent can be selected from water or a mixed solvent of water and a solvent compatible with water. Furthermore, the coating composition can be applied to form a coating film. Such paint compositions and coating films also make it possible to track or assist in tracking the scent or odor of the fragrance contained therein using a device or a means of discrimination or identification, such as a dog or other animal, that can discriminate or identify the scent or odor.

[0027] By providing a container having a plurality of holes formed so that the powder composition can pass through, and the powder composition to be poured into the container, an assistance device for tracking a search or tracking object can be constructed. Furthermore, by providing an object to be coated with a coating film formed by applying, spraying, impregnating, or printing a coating composition on the surface of the object to be coated with the coating composition, it is possible to construct an assistance device for searching for a search target or tracking a tracking target. By using such an assistance device, it is possible to track or assist in tracking the scent or odor of the fragrance contained in the powder composition or the coating film using a device capable of distinguishing or identifying the scent or odor, or a distinguishing or identifying means such as an animal such as a dog.

[Figure 4] FIG. 2 is a schematic diagram showing another example of a test method for a powder composition according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0030] Hereinafter, embodiments for carrying out the powder composition according to the present invention will be described in detail, but the present invention is not limited to these.

[0031] In the present invention, unless otherwise specified, the expressions "xx or more and xx or less" and "xx to xx" representing a numerical range mean a numerical range including the lower and upper limits, which are the endpoints. When a numerical range is described in stages, the upper and lower limits of each numerical range can be combined arbitrarily.

[0032] The powder composition of the present invention contains porous particles and a flavor component, and the flavor component is supported by the porous particles.

[0033] The porous particles are configured to be capable of carrying the fragrance component. Specifically, the porous particles have, as primary particles, one or more pores in a macropore region (macropores) and one or more pores smaller in size than the pores in the macropore region. The pores smaller in size than the macropores may be pores in a mesopore region (mesopores) and / or pores in a micropore region (micropores). In the present invention, the definitions of "macropore," "mesopore," and "micropore" are as defined by IUPAC (International Union of Pure and Applied Chemistry), where "macropore" refers to a pore (void) having a diameter of 50 nm or more, "mesopore" refers to a pore (void) having a diameter of 2 nm or more but less than 50 nm, and "micropore" refers to a pore (void) having a diameter of less than 2 nm. The pores can be measured, for example, using a pore analyzer.

[0034] In the present invention, the pores may be either recessed pores or through-holes, and these pores can function as regions in which the flavor components are carried and / or as flow paths for the flavor components when the flavor components are released from the porous particles (primary particles) to the outside.

[0035] Preferably, the porous particles are configured such that, as primary particles, the macropores have the function of carrying the fragrance component or carrying the fragrance component and functioning as a flow path for the fragrance component when the fragrance component is released, and pores smaller in size than the macropores have the function of a flow path for the fragrance component when the fragrance component is released, and the macropores and pores smaller in size than the macropores randomly penetrate each other. With this configuration, the perfume component present inside the macropores is released to the outside through the pores (through holes) that are smaller than the macropores.

[0036] More preferably, the porous particles are configured as primary particles such that the macropores carry the fragrance components and the pores smaller than the macropores function as flow paths for the fragrance components during release. All of the fragrance components may be supported (present or encapsulated) in the macropores, but as long as they are mainly supported in the macropores, a portion of them may be supported in pores smaller than the macropores.

[0037] The macropores may have a diameter of 50 nm or more, but are preferably configured to be capable of supporting the fragrance component therein, and more preferably configured to encapsulate the fragrance component therein. Therefore, the size of the macropores can be appropriately selected depending on the size of the fragrance component. The size of the macropores is preferably about 50 nm or more and 10 μm or less, and more preferably about 1 μm or more and 2 μm or less. The pore volume of the macropores is not particularly limited as long as the fragrance component is stably supported, but a larger pore volume is preferable. The pore volume can also be measured, for example, using a pore analyzer.

[0038] The pores smaller than the macropores are preferably large enough to allow the fragrance components to pass through, and the size of the pores can be appropriately selected depending on the size of the fragrance components. The pores smaller than the macropores are preferably mesopores, and the size of the mesopores is preferably 2 nm or more and 10 nm or less, more preferably 3 nm or more and 6 nm or less.

[0039] The size of the porous particles (primary particles) is not particularly limited as long as the pores can be formed, but the porous particles (primary particles) preferably have an average primary particle size (D50) of 0.5 μm or more and 20 μm or less, more preferably 1 μm or more and 10 μm or less, and even more preferably 2 μm or more and 5 μm or less.

[0040] The porous particles may be composed of inorganic porous fine particles. The inorganic porous fine particles are preferably those having excellent heat resistance, water resistance and corrosion resistance. Examples of inorganic compounds constituting the inorganic porous fine particles include: Alkaline earth metal carbonates such as calcium carbonate, barium carbonate, and magnesium carbonate; alkaline earth metal silicates such as calcium silicate, barium silicate, and magnesium silicate; alkaline earth metal phosphates such as calcium phosphate, barium phosphate, and magnesium phosphate; alkaline earth metal sulfates such as calcium sulfate, barium sulfate, and magnesium sulfate; metal oxides such as silica, titanium oxide, iron oxide, cobalt oxide, zinc oxide, nickel oxide, manganese oxide, and aluminum oxide; metal hydroxides such as iron hydroxide, nickel hydroxide, aluminum hydroxide, calcium hydroxide, and chromium hydroxide; other metal silicates such as zinc silicate and aluminum silicate; or other metal carbonates such as zinc carbonate and basic copper carbonate. Examples include:

[0041] The porous particles may be used alone or in combination of two or more kinds. It is more preferable to select porous silica fine particles as the inorganic porous fine particles.

[0042] The porous silica fine particles are commercially available, for example, as B-6C (trade name: Godball (Suzuki Yushi Kogyo Co., Ltd.)), etc. These porous silica fine particles are inorganic porous fine particles with high capsule strength.

[0043] The amount of the porous particles used is not particularly limited, but is, for example, 30% by mass or more, more preferably 30% by mass or more and 60% by mass or less, of the entire powder composition. If the amount used is less than 30% by mass, the effect of supporting the search or tracking of the target tends to be insufficient.

[0044] The fragrance component can be selected from substances that have a boiling point of 150° C. or higher and are liquid at temperatures between 10° C. and 30° C. Among these, it is preferable to select a natural substance that is safe for humans and animals (especially dogs) and that is not found in environments such as fields, mountains, or cities. For example, decanoic acids such as capric acid (decanoic acid), palmitic acid (hexadecanoic acid), and isopalmitic acid (2-hexyldecanoic acid); α-methyl ketones such as amyl methyl ketone (2-heptanone), 2-nonanone, and 2-undecanone; succinic acid esters such as menthyl succinate, diethyl succinate, and dimethyl succinate; and natural essential oil components such as 1,8-cineole and β-sesquiphellandrene. You can choose from: The fragrance components can be used alone or in combination of two or more.

[0045] Among these, it is preferable to select from capric acid, palmitic acid, amyl methyl ketone, and diethyl succinate. When the fragrance component is selected from capric acid, palmitic acid, amyl methyl ketone, and diethyl succinate, the powder composition has high fragrance or odor discrimination or distinguishability (discrimination or distinguishability by a discrimination or distinguishing means (e.g., an animal (especially a dog))) and long-lasting fragrance or odor. Considering the GHS classification of hazardous properties, it is more preferable to select diethyl succinate.

[0046] The amount of the flavor component carried is not particularly limited as long as it is an effective amount. The larger the amount of the flavor component carried, the more preferable it is, for example, 30% by mass or more, more preferably 40% by mass or more and 70% by mass or less, of the entire powder composition. If the amount loaded is less than 40% by mass, the effect of supporting the search or tracking of the target tends to be insufficient, and if it exceeds 70% by mass, the effect commensurate with the amount loaded will not be observed, making it uneconomical.In this example, the amount of the fragrance component loaded (loading amount) in the porous particles is about 60% by mass of the entire powder composition.

[0047] If necessary, various additives can be added to the powder composition of the present invention as long as they do not impair the object and effect of the present invention (such as the effect of supporting the search or tracking of a target). For example, gelling agents, pH adjusters, antioxidants, preservatives, antibacterial agents, dyes (pigments, etc.), ultraviolet absorbers, etc. may be added as appropriate.

[0048] When preparing the powder composition, there is no particular limitation on the method for supporting the flavor component on the porous particles, and various methods can be used for preparation. The flavor component can be supported on the porous particles, for example, by mixing the flavor component (or a solution containing the flavor component) with the porous particles. Preferably, the flavor component is supported on the porous particles by impregnating the porous particles with a solution containing the flavor component. As a method of impregnation, for example, a method can be selected in which the porous particles are immersed in a solution containing the flavor component under atmospheric pressure or reduced pressure to penetrate (impregnate) the porous particles. The solution containing the fragrance component can be prepared by mixing the fragrance component with an appropriate solvent. The solvent may be selected depending on the fragrance component to be used, as long as it allows the fragrance component to be dispersed so that the fragrance component can be supported on the porous particles. For example, the solvent may be selected from water or a mixed solvent of water and a solvent compatible with water (e.g., ethanol, 1-propanol, 2-propanol, ethylene glycol, propylene glycol).

[0049] In the present invention, the support of the flavor component on the porous particles is preferably carried out by a method in which the porous particles are immersed in a solution containing the flavor component under reduced pressure to penetrate (impregnate) the porous particles. For example, the impregnation can be carried out by the following method. (1) A solution containing a fragrance ingredient (and other additives, if necessary) is placed in a first container, while porous particles are placed in a second container. (2) The pressure inside each of the first container (the container into which the solution containing the fragrance component (and, if necessary, other additives) is placed) and the second container (the container into which the porous particles are placed) is reduced to create a vacuum. (3) A solution containing a flavor ingredient is poured from the first container into the second container. (4) After a predetermined time (for example, 30 minutes to 48 hours) has elapsed, the second container is returned to atmospheric pressure, and the solution therein is returned to the first container. (5) The porous particles (porous particles carrying the fragrance component) are removed. The impregnation may be carried out multiple times as necessary. The pressure during decompression can be appropriately set depending on the type of flavor component selected (particularly its boiling point).

[0050] A powder composition of this configuration enables the search for a search target or the tracking of a tracking target or assistance in the search for a search target by tracking the scent or odor of the fragrance contained in the powder composition using a scent or odor identifying means such as a device or an animal such as a dog that can distinguish or identify the scent or odor. That is, the powder composition can be used as a powder composition for searching for a search target or tracking a track target, or for supporting the same.

[0051] The powder composition can be used as it is (in the form of powder), or can be used in any form other than powder. For example, it can be used in the form of a liquid, gel, mist, aerosol, emulsion, suspension, or the like. Alternatively, the powder composition can be used in the form of a paint (paint composition).

[0052] A possible method for using the powder composition as is is to place the powder composition in a bag-shaped container (bag) having a plurality of holes (through holes) of a required size, and have the target (a potential search target or tracking target) carry this bag-shaped container in advance. Note that there are no particular limitations on the configuration of the bag-shaped container (bag), and any known or future-developed bag-shaped container (bag) can be used. Fig. 1 is a schematic diagram showing an example of a method for using the powder composition of one embodiment of the present invention as is. In Fig. 1, a bag-shaped container (bag body) 2 is sealed with upper and lower seals 2a and 2b, and has a plurality of holes 3 formed through the bottom of the bag body. A powder composition 1 is placed in this bag-shaped container 2. According to this method, the powder composition falls or detaches little by little from the hole, and the scent or odor of the fragrance component contained in the fallen or detached powder composition can be tracked using a device or a predetermined discrimination or identification means such as a dog or other animal that can distinguish or identify the scent or odor, making it possible to search for the search target or track the tracked target, or to assist in the search or tracking of the tracked target. 1, a plurality of holes 3 are formed, but the number of holes may be one. Furthermore, the search target and the tracking target are not limited to a person, but may be an animal or an object.

[0053] The powder composition can be used as a coating composition. The coating film formed by applying the coating composition also enables the search for a search target or the tracking of a tracked target, or assistance in the search, by tracking the scent or odor of the fragrance contained therein using a device or an animal such as a dog that can distinguish this.

[0054] The coating composition according to the present invention contains the powder composition, a solvent and / or a synthetic resin emulsion.

[0055] The solvent contained in the coating composition is not particularly limited as long as it enables dispersion of the powder composition so that it can be applied to a target object, etc. For example, water or a mixed solvent of water and a solvent compatible with water is selected as the solvent. When a mixed solvent of water and a solvent compatible with water is selected as the solvent, the quick-drying property of the composition tends to be improved.

[0056] Examples of the water-compatible solvent include: Ethanol, 1-propanol, 2-propanol, ethylene glycol, propylene glycol, etc. Examples include: The water-compatible solvents may be used alone or in combination of two or more.

[0057] The synthetic resin emulsion is a dispersion of a synthetic resin in water, and can be prepared by a conventional polymerization technique such as emulsion polymerization. When the coating composition contains the synthetic resin emulsion, the adhesion between the coating film and the substrate is improved and peeling of the coating film when left unused is prevented, thereby improving the life of the coating film and the product having the coating film.

[0058] As the synthetic resin, a resin such as an acrylic resin, a urethane resin, a vinyl chloride resin, a silicone resin, a vinyl acetate resin, a polyester resin, a styrene resin, or a fluororesin may be selected either alone or as a copolymer.

[0059] The synthetic resin emulsion is preferably selected from acrylic synthetic resin emulsions made from acrylic resins and styrene resins, and styrene-acrylic synthetic resin emulsions, from the viewpoints of paint suitability, physical properties of the coating film, and ease of availability.

[0060] The synthetic resin emulsion can be obtained as a commercially available product. 、 NeoRez R-966 (Covestro, polyether-based polyurethane resin emulsion); Sepolsion ES (Sumitomo Seika Chemicals, polyester-based resin emulsion) ;WEM-200U, WEM-505C (Taisei Fine Chemical Co., Ltd., acrylic-urethane resin emulsion); UW-550CS (Taisei Fine Chemical Co., Ltd., acrylic resin emulsion); Lubrijet N240 (Lubrizol Corporation, acrylic resin colloid); Superflex 150, 210, 420NS, 470, 500M, 620, 650, 740, E2000, E4800 (Dai-ichi Kogyo Seiyaku Co., Ltd., urethane resin emulsion or colloid); Vinyblanc A68J1 (Nissin Chemical Industry Co., Ltd., vinyl acetate-acrylic resin emulsion); Vinyblanc 278, 735 (Nissin Chemical Industry Co., Ltd., vinyl chloride-acrylic resin emulsion); Vinyblanc 1725, 1745 (Nissin Chemical Industry Co., Ltd., acrylic resin emulsion); Vinyblanc 1157 (Nissin Chemical Industry Co., Ltd., vinyl acetate resin emulsion); Movinyl 743N, 6520 (Japan Coating Resins Co., Ltd., acrylic resin emulsion); PRIMAL AC-261P, AC-808 (Dow Chemical Co., acrylic resin emulsion); NeoCryl Examples of the resin include, but are not limited to, A1092, A2091, A2092, A639, A655, A662 (DSM Coating Resin, styrene-acrylic resin emulsion); QE-1042, KE-1062 (Seiko PMC, styrene-acrylic resin emulsion); JE-1056 (Seiko PMC, acrylic resin emulsion); JONCRYL7199, PDX-7741 (BASF, styrene-acrylic resin emulsion); Chaline R-170S (Nissin Chemical Industry Co., Ltd., silicone-acrylic resin emulsion); Elitel KA-5034 (Unitika, polyester resin emulsion); and Polysol AP-1350 (Showa Denko, acrylic resin emulsion).

[0061] The content of the synthetic resin emulsion is not particularly limited, but is selected to be, for example, 3% by mass or more and 70% by mass or less of the total paint composition. The content of the synthetic resin emulsion is preferably 5% by mass or more and 45% by mass or less, more preferably 8% by mass or more and 40% by mass or less, and even more preferably 10% by mass or more and 33% by mass or less. When the content of the synthetic resin emulsion is within the above range, the coating composition is easily fixed to the object to be coated, and the coating composition fixed to the object to be coated is easily peeled off (easily detached or peeled off) by friction or the like.

[0062] If necessary, various paint additives can be added to the paint composition of the present invention as long as they do not impair the object and effect of the present invention (such as the effect of supporting the search or tracking of a target). For example, dyes, antifoaming agents, waxes, surface conditioners, viscosity adjusters, pH adjusters, preservatives, anticorrosives, rust inhibitors, ultraviolet absorbers, antioxidants, surfactants, etc. may be added as needed.

[0063] In particular, for the purpose of improving discrimination or distinguishability, pigments can be blended into the coating composition as long as the purpose and effect of the present invention are not impaired. There are no particular limitations on the pigments as long as they do not impair the objects and effects of the present invention.

[0064] Examples of the pigments include inorganic chromatic pigments such as ferric oxide (red iron oxide), yellow iron oxide, and ultramarine; organic chromatic pigments such as azo, naphthol, pyrazolone, anthraquinone, perylene, quinacridone, disazo, isoindolinone, benzimidazole, phthalocyanine, quinophthalone, and dioxazine; black pigments such as carbon black, iron-manganese composite oxide, iron-copper-manganese composite oxide, and black iron oxide; white pigments such as titanium oxide, zinc oxide, and alumina; and pearl pigments, aluminum pigments, photoluminescent pigments, phosphorescent pigments, and fluorescent pigments. Among these, it is preferable to select pigments that are not harmful to humans or animals (especially dogs). These pigments can be used alone or in combination.

[0065] When the pigment is blended into the coating composition, the coating composition is formulated so that the saturation of the coating film formed by application or the like is preferably 2 or more, more preferably 4 or more, and even more preferably 6.0 or more in terms of the Munsell color system. The "Munsell color system" is a system standardized by JIS Z8721 that expresses color using three parameters: hue, lightness, and saturation. The coating composition is preferably formulated so that the color of the coating film formed by application or the like falls within the range of 10YR to 10Y.

[0066] The content of the powder composition in the coating composition can be set taking into consideration the viscosity of the powder composition and the like, and is not particularly limited, but is preferably 5% by mass or more and less than 30% by mass, more preferably 10% by mass or more and 25% by mass or less, and even more preferably 10% by mass or more and 20% by mass or less, of the entire coating composition. If the content of the powder composition in the coating composition is less than 5% by mass, the scent or odor tends to be insufficient in terms of distinguishability (distinguishing ability) and long-term persistence, whereas if the content is 30% by mass or more, the viscosity tends to be too high, making application, etc., difficult.

[0067] The method for preparing the coating composition of the present invention is not particularly limited, and various methods can be used for preparation. For example, the coating composition of the present invention can be prepared by adding and mixing the powder composition and, if necessary, various additives to the solvent and / or synthetic resin emulsion. In this case, the order in which the various components are mixed is not particularly limited.

[0068] The viscosity of the coating composition is not particularly limited as long as it has a fluidity that allows it to be applied to an object to be coated.

[0069] The coating composition can be applied to various objects to be coated (objects to which the coating composition is to be coated, etc.). The material of the object to be coated is not particularly limited, but examples thereof include: Metals (aluminum, copper, iron, silver, nickel, titanium, stainless steel, and other alloys), ceramics (glass, etc.), plastics, wood, paper, woven fabrics, nonwoven fabrics, leather, and other fabrics. Among these, plastic is preferred.

[0070] Examples of the plastics include olefin resins (polyethylene, polypropylene, etc.), ethylene propylene diene resins, styrene acrylonitrile resins, polysulfone resins, polyphenylene ether resins, acrylic resins, silicone resins, fluorine resins, polyester resins, polyamide resins, polyimide resins, polystyrene resins, polyurethane resins, polycarbonate resins, norbornene resins, cellulose resins, polyvinyl alcohol resins, polyvinyl formal resins, polyvinyl butyral resins, polyvinyl pyrrolidone resins, polyvinyl acetate resins, polyvinyl acetal resins, polyvinyl chloride, engineering plastics, biodegradable plastics, olefin thermoplastic elastomers (TPO), styrene thermoplastic elastomers (TPS), polyester thermoplastic elastomers (TPEE), etc. The plastic object may be a plastic molded product having a shape corresponding to various product shapes, or may be a plastic film or plastic sheet (resin sheet).

[0071] By applying such a coating composition to the object to be coated by spraying, coating, adsorption, carrying, penetrating or impregnating, or by a known printing method such as flexographic printing, gravure printing, offset printing, letterpress printing or screen printing, it is possible to obtain the effect of searching for a search target or tracking a tracked target, or of assisting in the same. That is, the coating composition can be used as a coating composition for searching for a search target or tracking a tracked target, or for supporting the same.

[0072] In particular, the coating composition can be applied, sprayed, impregnated, or printed onto the surface of a substrate, particularly a sheet-like substrate such as a paper sheet, a cloth sheet, or a plastic sheet, to form a coating film, thereby achieving the effect of searching for a search target or tracking a tracked target, or assisting in the search. According to this invention, it is also possible to provide an assistance device for searching for a search target or tracking a tracking target, which comprises an object to be coated and a coating film formed by applying, spraying, impregnating or printing the paint composition on the surface of the object to be coated.

[0073] The coating composition can be applied to the sheet-like substrate so that the coating film has a thickness of 5 to 25 μm after application, thereby forming a coating film. Therefore, according to the present invention, it is also possible to provide a coating film obtained (formed) by painting (applying, etc.) the coating composition.

[0074] There are no particular limitations on the method of using the coating composition to search for a search target or track a track target or to assist in the same. FIG. 2 is a schematic diagram showing an embodiment of a coating composition according to one embodiment of the present invention for assisting in the search for a search target or the tracking of a tracked target. In Fig. 2, the object 6 is a 30 mm x 30 mm rectangular polypropylene plastic sheet. As shown in Fig. 2(B), one side (back side) of this sheet is coated with a coating composition 4, and the other side (front side) is provided with an adhesive layer. As shown in Fig. 2(A), nine such sheets are placed in a grid pattern on a 140 mm x 140 mm rectangular rubber plate (object to be placed) 5, with the side coated with the coating composition 4 facing downward. In other words, the coating composition or coating film is present between the sheet 6 and the plate 5. Note that in Fig. 2(B), the adhesive layer is composed of double-sided tape, but there are no particular limitations as long as it is adhesive. One possible method for searching or tracking a target is to place an object having such a paint composition or coating film (plate-shaped object 5 in Figure 2) at, for example, an entrance / exit of a front door based on the range of movement of the target (a potential target for search or tracking), and when the target goes out, the target or the paint composition or coating film on the target adheres to the target's shoes, etc., by tracking the scent or odor of the fragrance components of the target or paint composition or coating film that has adhered to the target, or at least part of the paint composition or coating film that has peeled off due to friction or other reasons during movement.

[0075] The powder composition, paint composition and coating film enable the search for a search target or the tracking of a tracked target or support for the search by tracking the scent or odor of the fragrance components contained therein using a predetermined means such as a device or an animal such as a dog that can distinguish or identify the scent or odor. Therefore, according to the present invention, it is also possible to provide a method for searching for a search target or tracking a tracked target, or for assisting in the same, by utilizing the powder composition, paint composition, and coating film, which enables the search for a search target or the tracking of a tracked target, or for assisting in the same.

[0076] For example, according to the present invention, in a method for supporting searching for a search target or tracking a tracking target, (A) Equipping the search target or the tracked target with a support device for searching the search target or tracking the tracked target, and / or attaching a coating to the search target or the tracked target by arranging a support device for searching the search target or tracking the tracked target based on the movement range of the search target or the tracked target; (b) A step of tracking the powder composition that has fallen or detached from the support device for searching for the search target or tracking the tracked target that is provided on the search target or the tracked target and / or at least a portion of the coating film that has detached or peeled off from the coating film attached to the search target or the tracked target using a means that can identify the fragrance component. It is possible to provide a method for assisting in searching for a search target or tracking a tracked target, including: [Example]

[0077] The present invention will be described in detail below with reference to examples, but the present invention is not limited to these examples. In the formulations of the following examples, "parts" are by mass unless otherwise specified.

[0078] [Test Example 1] Evaluation of the discriminability (discriminability) of fragrance ingredients The discrimination (discrimination power) of various fragrance ingredients was evaluated based on the following evaluation method. The fragrance ingredients used were palmitic acid, amyl methyl ketone, diethyl succinate, and capric acid, and these fragrance ingredients were evaluated by conducting tests with three randomly selected dogs. The results are shown in Table 1.

[0079] <Evaluation method> Five wide-mouthed bottles with an inner diameter of about 5 cm and a height of about 10 cm were prepared, and these were designated as bottles A to E. As shown in FIG. 3, bottles A to E were placed on the ground at equal intervals, and a hole F was created in the ground at a distance equal to this interval (the distance between the bottles) away from bottle E. The gauze to which a small amount of the fragrance ingredient had been applied was placed in one of bottles A to E or hole F, and the gauze to which no fragrance ingredient had been applied was placed in the remaining bottle or hole. The scent of the fragrance component was familiarized to a dog that had been previously trained to sit in front of a bottle or hole containing the fragrance component when it sensed the scent of the fragrance component. The dog was allowed to smell bottles A to E or hole F, and the distinctiveness of the fragrance ingredients was evaluated by determining whether or not it would sit in front of the bottle or hole containing the gauze coated with the fragrance ingredients according to the following evaluation criteria.

[0080] <Evaluation criteria> ◎: Able to identify (sat in front of the bottle or hole containing the gauze coated with the fragrance ingredient) ×: Could not identify

[0081] [Table 1]

[0082] <Results> All three dogs were able to identify the scent of the scented gauze. Therefore, it is clear that when the fragrance component in the powder composition of the present invention is selected from capric acid, palmitic acid, amyl methyl ketone, and diethyl succinate, the powder composition of the present invention will have an excellent effect in assisting in the search for a search target or the tracking of a tracked target.

[0083] [Example 1] The powder composition was prepared according to the following procedure. (1) 31.5 parts by mass of diethyl succinate (manufactured by Tokyo Chemical Industry Co., Ltd.) was prepared. This was placed in container A, and the pressure inside container A was reduced to create a vacuum. (2) 62.5 parts by mass of porous silica fine particles (Godball B-6C (manufactured by Suzuki Yushi Kogyo Co., Ltd.)) were placed in container B, and the pressure inside container B was reduced to create a vacuum. (3) The container A and the container B were connected, the solution in the container A was transferred into the container B, and the solution and the porous silica fine particles were mixed. (4) The pressure in container B was returned to atmospheric pressure, and only the liquid was transferred to container A. (5) The powder in container B was removed to obtain porous silica fine particles (powder composition) carrying the fragrance component diethyl succinate.

[0084] [Test Example 2] Evaluation of the distinguishability (discrimination power) of powder compositions The powder composition obtained in Example 1 above was evaluated for distinguishability based on the following evaluation method.

[0085] <Evaluation method> Five wide-mouthed bottles with an inner diameter of about 5 cm and a height of about 10 cm were prepared, and these were designated as bottles A to E. Bottles A through E were placed evenly spaced on the ground. The gauze with a small amount of powder composition attached thereto was placed in bottle A, and the gauze with no powder composition attached thereto was placed in the remaining bottles B to E. The scent of the powder composition was familiarized to a dog that had been previously trained to sit in front of a jar or hole containing the powder composition when it smelled the powder composition. The dog was allowed to sniff bottles A to E and was judged to see if it would sit in front of bottle A. The dog was then moved to a position where it could not see the bottles, and the positions of bottles A to E were changed. The dog was then allowed to smell bottles A to E again, and it was determined whether or not it would sit in front of bottle A.

[0086] <Results> The dog was able to identify (identify) the scent of the gauze to which the powder composition obtained in Example 1 was attached twice in a row. Therefore, it is clear that the powder composition of the present invention has an excellent effect in assisting the search for a search target or the tracking of a tracked target.

[0087] [Test Example 3] Evaluation of the discriminability (ability to be tracked) of powder compositions The powder composition obtained in Example 1 above was evaluated for discrimination power (ability to be tracked) based on the following evaluation method.

[0088] <Evaluation method> Approximately 0.3 g of the powder composition was placed in a small open-mouthed container, and a small amount of the powder composition was scattered around it. After the dog was trained to smell the powder composition, the dog was made to search for the small container (container containing the powder composition, specifically its smell ("smell" in Figure 4)) placed approximately 10 m away, as shown in Figure 4.

[0089] <Results> The dog was able to find (track) the small container containing the powder composition obtained in Example 1. Therefore, it is clear that the powder composition of the present invention has an excellent effect in assisting the search for a search target or the tracking of a tracked target.

[0090] [Example 2] A powder composition was prepared in the same manner as in Example 1, except that the flavor component was changed to capric acid.

[0091] [Example 3] A powder composition was prepared in the same manner as in Example 1, except that the flavor component was changed to palmitic acid.

[0092] [Example 4] A powder composition was prepared in the same manner as in Example 1, except that the fragrance component was changed to amyl methyl ketone.

[0093] [Examples 5 to 7] Using the powder composition obtained in Example 1 above, the components were mixed and stirred according to the formulation shown in Table 2 below to obtain a coating composition.

[0094] [Table 2]

[0095] [Test Example 4] Evaluation of the discriminability (ability to be tracked) of paint compositions Using the coating compositions obtained in Examples 5 to 7 above, samples were prepared according to the preparation method described below, and the discrimination ability (ability to be tracked) was evaluated according to the evaluation method described below.

[0096] <Sample preparation method> As in Figure 2(B), the coating compositions obtained in Examples 5 to 7 were applied to one side of a 30 mm x 30 mm rectangular polypropylene plastic sheet 41, so that layers were formed in the following order from the plastic sheet 41 side: layer (coating film) 42a of the coating composition obtained in Example 5, layer 42b of the coating composition obtained in Example 6, and layer 42c of the coating composition obtained in Example 7. Meanwhile, double-sided tape was attached to the other side of the plastic sheet as adhesive layer 43. Nine such plastic sheets were produced. Nine of the sheets obtained above were placed in a grid pattern on a 140 mm x 140 mm square rubber plate (substrate), with the side coated with the coating compositions 42a to 42c facing down, as shown in Figure 2(A).

[0097] <Evaluation method> One of the plastic sheets prepared by the above-mentioned method was attached to the sole of a shoe with the side on which the coating composition laminate was formed, i.e., the side on which coating compositions 42a to 42c were applied, facing down, and the subject walked approximately 350 m along the shoulder of a public road. The discrimination ability of the paint composition was evaluated by determining (verifying) whether a dog that had been trained to smell the fragrance component (diethyl succinate) could correctly track the walking route the day after the walk.

[0098] <Results> The dog (police dog) was able to track the scent of the coating composition (a laminate of the coating compositions obtained in Examples 5 to 7) applied to a plastic sheet. From the above, it is clear that the coating composition of the present invention is excellent in its support effect for searching for a search target or tracking a tracked target. Furthermore, a plate-like object with nine of the above plastic sheets placed on it was placed over the entrance, and when a person walked across the plate, several of the sheets placed on top of the plate stuck to their shoes. Therefore, it is clear that a coated object having the paint composition or coating film of this invention can be placed in a predetermined location based on the range of movement of the target (a potential target to be searched or tracked), and the target can be searched or tracked by tracking the scent or odor of the fragrance components contained in the coated object, the paint composition or coating film attached to the target, or at least a portion of the paint composition or coating film that has peeled off due to friction or the like during movement.
