[0006] Problems to be solved by the invention

[0007] The present invention aims to achieve high-precision decoration.

[0008] Means used to solve problems

[0009] The decorative article of the present invention comprises a substrate, a decorative layer and a base layer. The decorative layer contains a particle component. The base layer is arranged between the substrate and the decorative layer. The base layer has a covering portion and a peripheral portion. The covering portion is covered by the decorative layer. The peripheral portion is arranged at the periphery of the covering portion.

[0010] According to this structure, the peripheral edge of the base layer extends outward from the decorative layer and is not covered by the decorative layer. Therefore, the outer edge of the decorative layer is not easily affected by the outer edge or contour of the base layer, and the outer edge of the decorative layer can be easily formed with high precision.

[0011] In the decorative article according to the second aspect of the first aspect of the present invention, the decorative layer contains a volatile ink component. The volatile ink component has high fluidity. Therefore, when the decorative layer is formed, the volatile ink component smoothly spreads to the periphery. Therefore, the outer edge of the decorative layer can be easily and finely expressed.

[0012] In the decorative article according to the third aspect of the first or second aspect of the present invention, the particle component contains metal particles. According to this structure, a decorative layer with high brightness and excellent appearance can be obtained.

[0013] In the decorative article according to the fourth aspect of the third aspect of the present invention, the metal particles contain silver particles. According to this structure, a decorative layer with high brightness can be easily obtained.

[0014] In the fifth decorative article according to any one of the first to fourth aspects of the present invention, the maximum thickness of the decorative layer is not less than 20nm and not more than 80nm. According to this structure, since the thickness of the decorative layer is thin, the outer edge of the decorative layer can be finely expressed, thereby improving the decorativeness.

[0015] In the decorative article of claim 6 according to any one of the first to fifth aspects of the present invention, the base layer is thicker than the decorative layer. With this structure, a three-dimensional decoration can be obtained.

[0016] In the seventh decorative article according to any one of the first to sixth aspects of the present invention, the maximum thickness of the base layer is 80 μm or more and 150 μm or less. With this structure, a three-dimensional decoration can be obtained.

[0017] In the decorative article of claim 8 according to any one of claims 1 to 7 of the present invention, the maximum thickness of the covering portion is thicker than the maximum thickness of the peripheral portion. With this configuration, a three-dimensional decoration can be obtained.

[0018] In the ninth aspect of the decorative article according to any one of the first to eighth aspects of the present invention, the base layer contains an ultraviolet curing resin. According to this structure, the base layer can be easily cured, and the decoration can be easily produced.

[0019] In the decorative article of the tenth aspect according to the ninth aspect of the present invention, the surface of the base layer is leveled so as to have no corners. According to this structure, the outer edge of the decorative layer becomes smooth, thereby obtaining a good appearance.

[0020] In the decorative article of the eleventh aspect of the ninth aspect or the tenth aspect of the present invention, the surface of the peripheral portion is leveled so that there is no corner. According to this structure, the outer edge of the base layer becomes smooth. Therefore, even if the outer edge of the decorative layer is affected by the outer edge of the base layer, the outer edge of the decorative layer is not easily disordered, thereby obtaining a smooth outer edge of the decorative layer.

[0021] In addition, the fishing rod of the present invention comprises a fishing rod body and a three-dimensional display portion. The fishing rod body comprises a base material according to any one of the first to eleventh aspects. The three-dimensional display portion is applied to the fishing rod body. The three-dimensional display portion comprises a three-dimensional portion and a display portion. The three-dimensional portion is arranged on the fishing rod body. The three-dimensional portion comprises a base layer according to any one of the first to eleventh aspects. The display portion is arranged on a part of the three-dimensional portion. The display portion comprises a decorative layer according to any one of the first to eleventh aspects.

[0022] According to this structure, a fishing rod with excellent decorativeness can be obtained.

[0023] Effects of the Invention

[0024] As described above, since the peripheral edge of the base layer extends outward from the decorative layer, the outline of the decorative layer can be clearly formed, thereby improving the accuracy of decoration and the decorativeness of the article. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Hereinafter, a decorative article according to an embodiment of the present invention will be described with reference to the accompanying drawings. The decorative article (article) in this embodiment is a fishing rod. It should be noted that the article is not limited to a fishing rod, but may be an article for various purposes, such as a fishing tool such as a reel or a bicycle component other than a fishing rod.

[0031] Figure 1 The main parts of the fishing rod of this embodiment are shown. The fishing rod includes a fishing rod body 1 (equivalent to the "substrate" in the technical solution) and a three-dimensional display unit 2. The fishing rod body 1 is a so-called rod blank, preferably made of fiber-reinforced resin. The reinforcing fiber is carbon fiber, etc. The fishing rod body 1 can be hollow or solid. The fishing rod body 1 is the substrate.

[0032] A three-dimensional display portion 2 is provided on the surface of the fishing rod body 1. In the present embodiment, the three-dimensional display portion 2 is provided only on a portion of the entire circumference of the fishing rod body 1, but it may be provided on the entire circumference. Figure 2 and Figure 3 The details of the three-dimensional display unit 2 are shown in FIG. The three-dimensional display unit 2 has a three-dimensional unit 3 (equivalent to the "base layer" in the technical solution) and a display unit 4 (equivalent to the "decorative layer" in the technical solution). The surface of the three-dimensional display unit 2 is a curved surface such as a hemispherical surface, a dome shape, or a tunnel shape.

[0033] In this embodiment, the surface of the fishing rod body 1 is provided with a first base layer 10, a second base layer 11, and a three-dimensional display portion 2 in order from the radial inner side of the fishing rod body 1. In the three-dimensional display portion 2, the three-dimensional portion 3 is composed of a base layer 12, and the display portion 4 is composed of a decorative layer 13. It should be noted that in this embodiment, the first base layer 10 and the second base layer 11 are provided, but the three-dimensional display portion 2 may be provided directly on the surface of the base material, i.e., the fishing rod body 1, without providing a base layer. In addition, as Figure 3 As shown by the two-dot chain line in the figure, in this embodiment, a top coating layer 14 is provided as a protective layer on the surface of the second base layer 11 and the three-dimensional display part 2 (base layer 12, decorative layer 13), but it is also possible not to provide the top coating layer 14. Furthermore, a coating layer, an adhesive layer, etc. may be provided between the first base layer 10, the second base layer 11, the three-dimensional display part 2, and the top coating layer 14 as needed.

[0034] The first base layer 10 is preferably provided on the entire circumference of the surface of the fishing rod body 1. The thickness of the first base layer 10 may be fixed. The first base layer 10 may be colored or colorless, and may be transparent or opaque. The first base layer 10 includes various coatings, and may be acrylic polyurethane, acrylic melamine, epoxy, ester, etc. In the present embodiment, the first base layer 10 is composed of various coatings, but it may also be composed in the form of a laminated board or the like.

[0035] The second base layer 11 is arranged on the surface of the first base layer 10. The second base layer 11 can constitute a first pattern. The first pattern can be various patterns or texts. It should be noted that the above-mentioned three-dimensional display unit 2 constitutes a second pattern different from the first pattern. The thickness of the second base layer 11 can be fixed. The second base layer 11 is arranged in the area where the first base layer 10 is formed. The second base layer 11 overlaps the first base layer 10 on its surface as a base layer. The formation area of ​​the second base layer 11 is located in the formation area of ​​the first base layer 10. Therefore, the formation area of ​​the second base layer 11 is smaller than the formation area of ​​the first base layer 10. The second base layer 11 covers the entire first base layer 10 or a part thereof. It should be noted that the second base layer 11 can be arranged in one place or in multiple places. In addition, the second base layer 11 can be partially provided with an unprinted portion, i.e., a punching pattern portion. The punching pattern portion can be text or graphics, and the punching pattern portion can be formed in one place or in two or more places on a second base layer 11.

[0036] In the present embodiment, the second substrate layer 11 includes a single-component ink containing a blocked isocyanate. The single-component ink is particularly an ink for inkjet. The second substrate layer 11 can be formed by an inkjet printing device. The single-component ink includes a main agent and a curing agent. The main agent is a compound having active hydrogen, and the curing agent is an isocyanate compound. The single-component ink is a blocked ink, having a blocked isocyanate obtained by masking the isocyanate with a blocking agent. The blocked isocyanate is dissociated from the blocking agent by heating, and the isocyanate group is regenerated. It should be noted that the blocking agent can also be dissociated by light instead of heat.

[0037] The one-component ink may be a one-component polyurethane resin coating composed of a blocked isocyanate and a polyol. The blocked isocyanate is obtained by reacting various isocyanate compounds with various end-capping agents. The raw material for the blocked isocyanate, i.e., the isocyanate compound, may be of various types, for example, diphenylmethane diisocyanate (MDI), methyl isocyanate (MIC), hexamethylene diisocyanate (HDI), toluene diisocyanate (TDI), isophorone diisocyanate (IPDI), etc.

[0038] The end-capping agent may be of various types, including alcohols, ε-caprolactam, phenols, oximes, active methylene compounds, etc. In addition, the polyol may be of various types, for example, it may be acrylate polyol, polyester polyol, polycarbonate polyol, etc.

[0039] It should be noted that the single-component ink includes a solvent, a dye or a pigment, and a dispersant. In addition, in addition to the blocked isocyanate, various isocyanates that are not covered by the end-capping agent may also be contained. However, in the case of containing the uncovered isocyanate, the isocyanate is less than the blocked isocyanate. It should be noted that in the present embodiment, the second base layer 11 is formed by inkjet printing and is formed by inkjet printing, but it can also be formed in the same manner as the first base layer 10 by attaching a laminate, etc.

[0040] In this embodiment, the three-dimensional display unit 2 is disposed on the surface of the second base layer 11. Specifically, the base layer 12 of the three-dimensional display unit 2 is disposed in the formation area of ​​the second base layer 11 and covers at least a portion of the second base layer 11. The base layer 12 is transparent and can be colorless and transparent or colored and transparent. The surface of the base layer 12 is a curved surface such as a hemispherical surface, a dome shape, or a tunnel shape.

[0041] The base layer 12 can be made of, for example, Figure 4The inkjet printer is formed by an inkjet printer as shown. The inkjet printer includes: an ink cartridge 20 that stores ink coating; and a print head 21 that applies the ink coating supplied from the ink cartridge 20 to an object. Basic colored inks are cyan, magenta, yellow and black inks. However, white or silver, etc. can also be used as needed. The print head 21 is configured with a plurality of ejection nozzles that supply cyan, magenta, yellow and black inks as ink droplets. Each ejection nozzle is provided with a plurality of ejection holes. In addition, the inkjet printer includes a heating medium. The heating medium receives operation information from a control means not shown in the figure, quickly heats the ink and causes it to dropletize and eject through bubbles. This method is called a thermal foaming method. However, a piezoelectric method can also be used. Furthermore, the inkjet printer includes an ultraviolet irradiation device 22. The fishing rod body 1 is mounted on the spindle 23. By rotating the spindle 23 around the axis, the fishing rod body 1 rotates together with the spindle 23. Then, the print head 21 is moved along the axis of the mandrel 23. The coating method can be a multi-path method. In the multi-path method, the print head 21 does not coat in one stroke, but moves to the same part multiple times to coat. The number of paths is arbitrary.

[0042] The UV ink droplets are ejected from the ejection nozzle and irradiated with ultraviolet light from the ultraviolet irradiation device 22, so that the ink is hardened and fixed. The height, extension and shape of the base layer 12 can be adjusted by adjusting the viscosity of the UV ink, the time from the attachment of the ejected ink droplets to the ultraviolet irradiation, and the amount of ultraviolet light. At this time, since the UV ink droplets are ejected, the Figure 2 As shown in the first outer edge 12a and the second outer edge 13a, a continuous circle is formed with unclear outline. It should be noted that Figure 2 This is an exaggerated diagram and is somewhat different from the actual one. UV ink can be a photopolymerizable type, containing a resin that is hardened by ultraviolet rays. The ultraviolet curing resin can be various free radical polymerization resins, or various oligomers or monomers. Oligomers can include epoxy acrylates, polyurethane acrylates, and polyether acrylates. Photoinitiators can also be of various types, including benzophenone series, benzoin series, acetophenone series, thioxanthone series, acylphosphine oxide series, etc. It should be noted that UV inks include defoaming agents, etc. in addition to these photopolymerizable oligomers and photoinitiators.

[0043] like Figure 2As shown, the base layer 12 is divided into two parts: a covering part 121 and a peripheral part 122. The covering part 121 is a part covered by the decorative layer 13. The peripheral part 122 is a part not covered by the decorative layer 13, which is provided at the periphery of the covering part 121 and is equivalent to the peripheral part of the base layer 12. Among the base layer 12, only the covering part 121 is covered by the decorative layer 13. The decorative layer 13 is formed in a narrower range than the base layer 12. The covering part 121 is entirely covered by the decorative layer 13. The peripheral part 122 is a part extending outward from the decorative layer 13. The peripheral part 122 is an area between the second outer edge 13a of the decorative layer 13 and the first outer edge 12a of the base layer 12, and is divided by the second outer edge 13a of the decorative layer 13 and the first outer edge 12a of the base layer 12. The peripheral part 122 is formed around the covering part 121. The peripheral part 122 is a edging part for edging the decorative layer 13. The outer edge of the peripheral portion 122 is the first outer edge 12 a of the base layer 12 .

[0044] Since the ink droplets of UV ink are ejected from the inkjet printer, Figure 3 As shown, the thickness of the base layer 12 is not constant. The thickness of the coating 121 is thicker than the thickness of the peripheral portion 122. The base layer 12 is a convex shape protruding radially outward from the fishing rod body 1. The thickness of the base layer 12 gradually increases from the first outer edge 12a to the coating 121, that is, from the peripheral portion 122 side to the coating 121 side. The thickness of the base layer 12 is the thickest at its central portion, and gradually decreases from there to the first outer edge 12a. The thickness of the base layer 12 is the thinnest at the first outer edge 12a. The maximum thickness of the base layer 12 is preferably 80 μm or more and 150 μm or less, so that a three-dimensional effect can be obtained. However, in the future, when pattern printing is applied to perform three-dimensional display, the maximum thickness is expected to exceed 150 μm and reach about 300 μm. The maximum thickness of the coating 121 is the maximum thickness of the base layer 12. The maximum thickness of the coating 121 is thicker than the maximum thickness of the peripheral portion 122. The maximum thickness of the peripheral portion 122 is equal to the minimum thickness of the coating 121. The maximum thickness of the base layer 12 is thicker than the thickness of the second base layer 11. The base layer 12 can be provided at the gripping portion of the fishing rod body 1, and the convex shape of the base layer 12 can provide good decorativeness and good gripping power.

[0045] The surface of the base layer 12 is leveled so that it has no corners. That is, after the ink droplets of the UV ink are inked, gloss can be obtained by setting a certain adaptation time (leveling time). By leveling, the surface of the peripheral portion 122 can be constructed to have no corners. The thickness of the base layer 12 can be formed by printing in a multiple overlapping manner using an inkjet printing device. If overlapping is performed, it can be adjusted to any thickness. The maximum thickness of the base layer 12 can be easily adjusted to a preferred range of 80 μm or more and 150 μm or less. In the case of forming the base layer 12 by the above-mentioned inkjet printer, for example, while the fishing rod body 1 is rotated about its central axis, the print head 21 of the inkjet printer is scanned along the central axis direction of the fishing rod body 1. The base layer 12 can be easily formed by printing a prescribed pattern by an inkjet printer and then curing it by ultraviolet irradiation of the ultraviolet irradiation device 22. In this way, the base layer 12 is formed by the inkjet printer, so that the surface of the base layer 12 is leveled and has a smooth surface without corners, and a convex shape with a thickness of 80 μm to 150 μm is obtained.

[0046] like Figure 2 As shown, the first outer edge 12a of the base layer 12 (the outer edge of the peripheral portion 122) is formed with a first waveform portion 12b that swings in the inner and outer directions. The first waveform portion 12b is continuously arranged along the first outer edge 12a of the base layer 12 (the outline of the base layer 12). The first waveform portion 12b is formed by ink droplets of ink that form the base layer 12. The first waveform portion 12b has a swing amount in the inner and outer directions, namely a first swing amount 12c. The first swing amount 12c shows the degree of serration of the first outer edge 12a. It should be noted that the first waveform portion 12b can be regularly arranged along the first outer edge 12a of the base layer 12, or it can be irregularly arranged. The first swing amount 12c can be an average value.

[0047] The decorative layer 13 is disposed on the surface of the base layer 12. In the present embodiment, the inkjet printer described above is used to mainly eject ink droplets of volatile ink from the ejection nozzle and fix them. The decorative layer 13 is disposed in the formation area of ​​the base layer 12 to prevent it from extending outward from the formation area of ​​the base layer 12. The second outer edge 13a of the decorative layer 13 is the outer edge of the formation area of ​​the decorative layer 13, and the first outer edge 12a of the base layer 12 is the outer edge of the formation area of ​​the base layer 12. The second outer edge 13a of the decorative layer 13 is located further inward than the first outer edge 12a of the base layer 12. The surface of the decorative layer 13 is a curved surface such as a hemispherical surface or a dome shape.

[0048] The decorative layer 13 contains a particle component. The particle component includes metal particles. The metal particles use any one of silver, gold, copper, nickel, chromium, platinum, palladium and their alloys or any mixture thereof, preferably including silver. The metal particles can be metal particles precipitated by heating a metal complex, or metal particles that are already in a particle state at room temperature. The metal particles are nanoparticles, and their particle size is, for example, about 1nm to 100nm. The decorative layer 13 preferably contains a volatile ink component. The volatility of the ink forming the decorative layer 13 is higher than the volatility of the ink forming the base layer 12. The decorative layer 13 can be formed by inkjet ink, and it is also preferred to form the decorative layer 13 by applying the ink by an inkjet printer. As an example, a silver metal complex using an amine as a ligand can be used. The silver metal complex can be made fluid by diluting it with alcohol. Since the silver nanoparticles precipitated by heating are melted and connected to each other, the surface density is high and they are tightly connected. Alternatively, the decorative layer 13 can be formed by dispersing and coating metal particles at a thickness of 0.01 μm or more, preferably 0.02 μm or more, and heating at a predetermined temperature so that the metal particles are sintered and the particle interfaces are metal-bonded and integrated. In particular, nanoparticles of silver or its alloy, or a mixture of silver nanoparticles and nanoparticles of other metals, are suitable because they begin to sinter at a relatively low temperature, for example, about 100°C.

[0049] The thickness of the decorative layer 13 may be fixed or gradually increase from the second outer edge 13a of the decorative layer 13 to the central portion of the decorative layer 13. The maximum thickness of the decorative layer 13 is preferably greater than 20 nm and less than 80 nm. The maximum thickness of the decorative layer 13 is thinner than the maximum thickness of the base layer 12. The thickness of the second outer edge 13a of the decorative layer 13 is thinner than the thickness of the outer edge of the covering portion 121 of the base layer 12.

[0050] like Figure 2 As shown, the second outer edge 13a of the decorative layer 13 is formed with a second waveform 13b that swings in the inner and outer directions. The second waveform 13b is continuously arranged along the second outer edge 13a (contour) of the decorative layer 13. The second waveform 13b is formed by ink droplets of ink forming the decorative layer 13. The second waveform 13b has a swing amount in the inner and outer directions, that is, a second swing amount 13c in the inner and outer directions. The second swing amount 13c shows the degree of sawtooth of the second outer edge 13a. It should be noted that the second waveform 13b can be regularly arranged along the second outer edge 13a of the decorative layer 13, or it can be irregularly arranged. The second swing amount 13c can be an average value. The second swing amount 13c is smaller than the first swing amount 12c. The second waveform 13b is a small and fine swing, and the first waveform 12b is a larger and rough swing than the second waveform 13b. It should be noted that a single layer or more than two layers of intermediate layers can be arranged between the base layer 12 and the decorative layer 13.

[0051] The top coating layer 14 is made of transparent or translucent synthetic resin such as epoxy, polyurethane, acrylic, acrylic silicon, etc. The top coating layer 14 preferably covers the entire decorative layer 13 , and preferably covers the entire base layer 12 .

[0052] As described above, the peripheral portion 122 of the base layer 12 extends outward from the outer edge of the decorative layer 13. Therefore, the outer edge, i.e., the outline of the decorative layer 13 is not easily affected by the outer edge of the peripheral portion 122 of the base layer 12, and becomes a clear outline. The first corrugated portion 12b is larger than the second corrugated portion 13b. Therefore, by the outer edge of the decorative layer 13 moving away from the first corrugated portion 12b to the inside, the outer edge of the decorative layer 13 is not easily affected by the first corrugated portion 12b, and the outer edge of the decorative layer 13 can be clearly formed.
