[0003] [Patent Document 1] JP 2017-202592 A Summary of the Invention [Problem to be solved by the invention]

[0004] An object of the present invention is to improve the precision of decoration. [Means for solving the problem]

[0005] The decorative article according to the present invention comprises a substrate, a decorative layer, and a base layer. The decorative layer contains a particle component. The base layer is provided between the substrate and the decorative layer. The base layer has a covering portion and a peripheral portion. The covering portion is covered with the decorative layer. The peripheral portion is provided on the peripheral edge of the covering portion.

[0006] According to this configuration, the peripheral portion of the base layer is not covered by the decorative layer and protrudes outward from the decorative layer, so that the outer edge of the decorative layer is less affected by the outer edge, i.e., the contour, of the base layer, making it easier to form the outer edge of the decorative layer with high accuracy.

[0007] 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 forming the decorative layer, the volatile ink component spreads smoothly around. Therefore, the outer edge of the decorative layer can be easily and finely expressed.

[0008] 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. This configuration provides a decorative layer with high brightness and excellent aesthetics.

[0009] In the decorative article according to the fourth aspect of the third aspect of the present invention, the metal particles contain a silver particle component. With this configuration, a decorative layer with high brightness can be easily obtained.

[0010] In the decorative article of a fifth aspect according to any one of the first to fourth aspects of the present invention, the maximum thickness of the decorative layer is 20 nm or more and 80 nm or less. With this configuration, since the thickness of the decorative layer is thin, the outer edge of the decorative layer can be expressed finely, and the decorativeness is enhanced.

[0011] In a decorative article according to a sixth aspect of the present invention, the thickness of the base layer is greater than the thickness of the decorative layer, and this structure provides a decoration with a three-dimensional effect.

[0012] In the 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 configuration, a decoration with a three-dimensional effect can be obtained.

[0013] In the decorative article according to any one of the first to seventh aspects of the present invention, the maximum thickness of the covering portion is greater than the maximum thickness of the peripheral edge portion. With this configuration, a decoration with a three-dimensional effect can be obtained.

[0014] In a decorative article according to a ninth aspect of the present invention, the base layer contains an ultraviolet curable resin. With this configuration, the base layer can be easily cured, making it easy to create the decoration.

[0015] 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 edges. With this configuration, the outer edge of the decorative layer is smooth, and a good appearance is obtained.

[0016] In the decorative article of the eleventh aspect according to the ninth or tenth aspect of the present invention, the surface of the peripheral portion is leveled so that there are no edges. With this configuration, the outer edge of the base layer is 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 unlikely to be disturbed, and a smooth outer edge of the decorative layer can be obtained.

[0017] The fishing rod according to the present invention also includes a fishing rod body and a three-dimensional display part. The fishing rod body is made of a base material according to any one of the above-mentioned first to eleventh side faces. The three-dimensional display part is applied to the fishing rod body. The three-dimensional display part has a three-dimensional part and a display part. The three-dimensional part is provided on the fishing rod body. The three-dimensional part is made of a base layer according to any one of the above-mentioned first to eleventh side faces. The display part is provided on a part of the three-dimensional part. The display part is made of a decorative layer according to any one of the above-mentioned first to eleventh side faces.

[0018] This configuration provides a highly decorative fishing rod. Effect of the Invention

[0019] As described above, since the peripheral edge of the base layer extends outside the decorative layer, the contour of the decorative layer can be formed sharply, the precision of the decoration is increased, and the decorativeness of the article can be improved.

[Diagram 5] FIG. 11 is a cross-sectional view of a main portion of a conventional decorative article. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] A decorative article according to one embodiment of the present invention will be described below with reference to the drawings. The decorative article (article) in this embodiment is a fishing rod. However, the article is not limited to a fishing rod and may be used for various purposes, such as fishing tackle other than a fishing rod, such as a reel, or a bicycle part.

[0022] FIG. 1 shows the main parts of the fishing rod of this embodiment. The fishing rod comprises a fishing rod main body 1 (corresponding to the "substrate" in the claims) and a three-dimensional display part 2. The fishing rod main body 1 is a so-called blank, and is preferably made of fiber-reinforced resin. The reinforcing fiber is carbon fiber or the like. The fishing rod main body 1 may be hollow or solid. The fishing rod main body 1 is the substrate.

[0023] A three-dimensional display section 2 is provided on the surface of the fishing rod body 1. In this embodiment, the three-dimensional display section 2 is provided only on a part of the entire circumference of the fishing rod body 1, but it may be provided over the entire circumference. Details of the three-dimensional display section 2 are shown in Figs. 2 and 3. The three-dimensional display section 2 has a three-dimensional section 3 (corresponding to the "base layer" in the claims) and a display section 4 (corresponding to the "decorative layer" in the claims). The surface of the three-dimensional display section 2 is a curved surface such as a hemisphere, dome shape, tunnel shape, or the like.

[0024] 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 section 2 in this order from the radially inner side of the fishing rod body 1. In the three-dimensional display section 2, a three-dimensional section 3 is formed from a base layer 12, and a display section 4 is formed from a decorative layer 13. In this embodiment, the first base layer 10 and the second base layer 11 are provided, but the three-dimensional display section 2 may be provided directly on the surface of the fishing rod body 1, which serves as a base material, without providing a base layer. In addition, as shown by the two-dot chain line in FIG. 3, in this embodiment, a top coat layer 14 is provided as a protective layer on the surfaces of the second base layer 11 and the three-dimensional display section 2 (base layer 12, decorative layer 13), but the top coat layer 14 may not be provided. Furthermore, a coating layer, an adhesive layer, or the like may be provided between the first base layer 10, the second base layer 11, the three-dimensional display section 2, and the top coat layer 14, as necessary.

[0025] The first base layer 10 is preferably provided over the entire circumference of the surface of the fishing rod body 1. The thickness of the first base layer 10 may be constant. The first base layer 10 may be colored or colorless, and may be transparent or opaque. The first base layer 10 is made of various types of paint, and may be acrylic urethane, acrylic melamine, epoxy-based, ester-based, or the like. In this embodiment, the first base layer 10 is made of various types of paint, but it may also be made by attaching a laminate sheet or the like.

[0026] The second base layer 11 is provided on the surface of the first base layer 10. The second base layer 11 can form a first pattern. The first pattern may be various designs or characters. The above-mentioned three-dimensional display unit 2 forms a second pattern different from the first pattern. The thickness of the second base layer 11 may be constant. The second base layer 11 is provided in the area where the first base layer 10 is formed. The second base layer 11 is superimposed on the surface of the first base layer 10 as a base layer. The formation area of ​​the second base layer 11 is within 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 whole or a part of the first base layer 10. The second base layer 11 may be provided in one place or in multiple places. Also, the second base layer 11 may be partially provided with a cutout pattern part that is a part that is not printed. The cut-out pattern portion may be a letter or a figure, and may be formed in one place on one second undercoat layer 11, or may be formed in two or more places.

[0027] In this embodiment, the second underlayer 11 is made of a one-liquid ink containing a blocked isocyanate. The one-liquid ink is particularly an ink for inkjet printing. The second underlayer 11 can be formed by an inkjet printing device. The one-liquid ink contains a base agent and a curing agent. The base agent is a compound having active hydrogen, and the curing agent is an isocyanate compound. The one-liquid ink is of a block type, and contains a blocked isocyanate in which the isocyanate is masked with a blocking agent. The blocking agent of the blocked isocyanate is dissociated by heating, and the isocyanate group is regenerated. The blocking agent may be dissociated by light instead of heat.

[0028] The one-liquid ink may be a one-liquid polyurethane resin paint made of a blocked isocyanate and a polyol. The blocked isocyanate is obtained by reacting various isocyanate compounds with various blocking agents. The isocyanate compound, which is the raw material used for the blocked isocyanate, may be various, for example, diphenylmethane diisocyanate (MDI), methyl isocyanate (MIC), hexamethylene diisocyanate (HDI), toluene diisocyanate (TDI), isophorone diisocyanate (IPDI), etc.

[0029] The blocking agent may be of various types, such as alcohols, ε-caprolactam, phenols, oximes, active methylene compounds, etc. The polyol may be of various types, such as acrylic polyol, polyester polyol, polycarbonate polyol, etc.

[0030] The one-component ink contains a solvent, a dye or pigment, and a dispersant. In addition to the blocked isocyanate, various isocyanates that are not masked with a blocking agent may be contained. However, when an unmasked isocyanate is contained, the amount of the isocyanate is less than that of the blocked isocyanate. In this embodiment, the second base layer 11 is formed by inkjet printing using inkjet ink, but it can also be formed by attaching a laminate sheet or the like, like the first base layer 10.

[0031] In this embodiment, the stereoscopic display unit 2 is provided on the surface of the second foundation layer 11. Specifically, the base layer 12 of the stereoscopic display unit 2 is provided within the formation region of the second foundation layer 11, and covers at least a part of the second foundation layer 11. The base layer 12 is transparent, and may 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, a tunnel shape, or the like.

[0032] The base layer 12 can be formed by using an inkjet printer as shown in FIG. 4, for example. The inkjet printer includes a tank 20 that stores ink paint, and a head 21 that applies the ink paint supplied from the tank 20 to an object. The basic color inks are cyan, magenta, yellow, and black inks. However, white, silver, and the like may be used as necessary. The head 20 is provided with a plurality of ejection nozzles that supply the cyan, magenta, yellow, and black inks as droplets. Each ejection nozzle is provided with a large number of ejection holes. The inkjet printer is also provided with a heating medium. The heating medium receives operation information from a control means (not shown), rapidly heats the ink to promote the formation of droplets, and ejects the ink by air bubbles. This method is called a thermal jet method. However, a piezo method may also be adopted. Furthermore, the inkjet printer is provided with an ultraviolet ray irradiation device 22. The fishing rod body 1 is attached to a mandrel 23. The mandrel 23 is rotated around its axis, causing the fishing rod body 1 to rotate together with the mandrel 23. Then, the head 21 is moved along the axis of the mandrel 23. The coating can be performed in a multi-pass manner. In the multi-pass manner, the head 21 does not coat in a single pass, but instead moves to the same location multiple times to coat. The number of passes is arbitrary.

[0033] Droplets of UV ink are discharged from the discharge nozzle, and the ink is cured and fixed by irradiating ultraviolet rays from the ultraviolet irradiator 22. The height, spread, and shape of the base layer 12 can be adjusted by adjusting the viscosity of the UV ink, the time from when the discharged ink droplets are attached until the ultraviolet rays are irradiated, and the amount of ultraviolet light. In this case, since the UV ink droplets are discharged, they become a continuous circle, as shown by the first outer edge 12a and the second outer edge 13a in FIG. 2, and the outline is not sharp. Note that FIG. 2 is an exaggerated illustration, and may differ slightly from the actual situation. The UV ink may be of a photopolymerization type, and contains a resin that is cured by ultraviolet rays. The ultraviolet curing resin may be various types of radical polymerization resins, and may be various types of oligomers or monomers. Examples of oligomers include epoxy acrylate, urethane acrylate, and polyether acrylate. Various types of photopolymerization initiators may also be used, such as benzophenone-based, benzoin-based, acetophenone-based, thioxanthone-based, and acylphosphine oxide-based. In addition to the photopolymerizable oligomer and photopolymerization initiator, the UV ink contains an antifoaming agent.

[0034] As shown in FIG. 2, the base layer 12 is divided into two parts, a covering portion 121 and a peripheral portion 122. The covering portion 121 is a portion covered by the decorative layer 13. The peripheral portion 122 is a portion not covered by the decorative layer 13, provided on the periphery of the covering portion 121, and corresponds to the peripheral portion of the base layer 12. Only the covering portion 121 of the base layer 12 is covered by the decorative layer 13. The decorative layer 13 is formed in an area narrower than the base layer 12. The covering portion 121 is entirely covered by the decorative layer 13. The peripheral portion 122 is a portion protruding outward from the decorative layer 13. The peripheral portion 122 is a region 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 portion 122 is formed around the covering portion 121. The peripheral edge portion 122 is a border portion that borders the decorative layer 13. The outer edge of the peripheral edge portion 122 is the first outer edge 12a of the base layer 12.

[0035] Since droplets of UV ink are ejected from an inkjet printer, the thickness of the base layer 12 is not constant as shown in FIG. 3. The thickness of the covering portion 121 is thicker than the thickness of the peripheral portion 122. The base layer 12 has a convex shape that protrudes radially outward from the fishing rod body 1. The thickness of the base layer 12 gradually increases from the first outer edge 12a toward the covering portion 121, that is, from the peripheral portion 122 side toward the covering portion 121 side. The thickness of the base layer 12 is the thickest at its center portion, and gradually decreases from there toward the first outer edge 12a. The thickness of the base layer 12 is the thinnest at the first outer edge 12a. In general, the maximum thickness of the base layer 12 is preferably 80 μm or more and 150 μm or less, and a three-dimensional effect is obtained. However, in the future, when graphic printing or the like is applied to display three-dimensionally, it is expected that the maximum thickness will exceed 150 μm and reach about 300 μm. The maximum thickness of the covering portion 121 is the maximum thickness of the base layer 12. The maximum thickness of the covering portion 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 covering portion 121. The maximum thickness of the base layer 12 is thicker than the thickness of the second foundation layer 11. The base layer 12 may be provided on the grip portion of the fishing rod body 1, and the convex shape of the base layer 12 provides good decorativeness as well as good gripping force.

[0036] The surface of the base layer 12 is leveled so that there are no edges. That is, after the droplets of the UV ink land, a certain time for blending (leveling time) is provided, and thus gloss can be obtained. By leveling, the surface of the peripheral portion 122 can be configured so that there are no edges. The thickness of the base layer 12 may be formed by printing multiple times by an inkjet printing device. By performing multiple coatings, the thickness can be adjusted arbitrarily. The maximum thickness of the base layer 12 can be easily adjusted to preferably 80 μm or more and 150 μm or less. When the base layer 12 is formed by the above-mentioned inkjet printing machine, for example, the head 21 of the inkjet printing machine is scanned along the central axis direction of the fishing rod body 1 while rotating the fishing rod body 1 around its central axis. The base layer 12 can be easily formed by printing a predetermined pattern by the inkjet printing machine, and then curing it by ultraviolet irradiation by the ultraviolet irradiation device 22. By forming the base layer 12 in this manner using an inkjet printer, the surface of the base layer 12 is leveled, resulting in a smooth surface without edges and a convex shape with a thickness of 80 μm or more and 150 μm or less.

[0037] As shown in FIG. 2, a first wavy portion 12b swaying inward and outward is formed on the first outer edge 12a (the outer edge of the peripheral portion 122) of the base layer 12. The first wavy portion 12b is continuously provided along the first outer edge 12a (the outline of the base layer 12) of the base layer 12. The first wavy portion 12b is formed by droplets of ink forming the base layer 12. The first wavy portion 12b has a first deflection amount 12c which is a deflection amount in the inward and outward direction. The first deflection amount 12c indicates the degree of jaggedness of the first outer edge 12a. The first wavy portion 12b may be provided regularly or irregularly along the first outer edge 12a of the base layer 12. The first deflection amount 12c may be an average value.

[0038] The decorative layer 13 is provided on the surface of the base layer 12. In this embodiment, the above-mentioned inkjet printer is used to eject and fix mainly volatile ink droplets from the ejection nozzle. The decorative layer 13 is provided within the formation region of the base layer 12 so as not to protrude outside the formation region of the base layer 12. The second outer edge 13a of the decorative layer 13 is the outer edge of the formation region of the decorative layer 13, and the first outer edge 12a of the base layer 12 is the outer edge of the formation region of the base layer 12. The second outer edge 13a of the decorative layer 13 is located inside the first outer edge 12a of the base layer 12. The surface of the decorative layer 13 is a curved surface such as a hemisphere or a dome shape.

[0039] The decorative layer 13 contains a particle component. The particle component includes metal particles. The metal particles are any one of silver, gold, copper, nickel, chromium, platinum, palladium, and alloys thereof, or a mixture thereof, and preferably contain silver. The metal particles may be precipitated by heating a metal complex, or may be already in a particle state at room temperature. The metal particles are nanoparticles, and the particle size is, for example, about 1 to 100 nm. The decorative layer 13 preferably contains a volatile ink component. The ink forming the decorative layer 13 is more volatile than the ink forming the base layer 12. The decorative layer 13 can be formed from an ink for inkjet printing, and it is also preferable to form the decorative layer 13 by applying the ink with an inkjet printer. As an example of this, a silver metal complex having an amine as a ligand can be used. The silver metal complex can be made fluid by diluting it with alcohol. The silver nanoparticles precipitated by heating are melted and connected to each other, so that the surface density is high and the connection is tight. Alternatively, metal particles can be dispersed and applied to a thickness of 0.01 μm or more, preferably 0.02 μm or more, and heated at a predetermined temperature to sinter the metal particles and integrate the particle interfaces through metallic bonding to form the decorative layer 13. In particular, nanoparticles made of silver or an alloy thereof, or a mixture of silver nanoparticles and nanoparticles of another metal are suitable because they start to sinter at a relatively low temperature, for example, around 100° C.

[0040] The thickness of the decorative layer 13 may be constant, or may gradually increase from the second outer edge 13a of the decorative layer 13 toward the central portion of the decorative layer 13. The maximum thickness of the decorative layer 13 is preferably 20 nm or more and 80 nm or less. The maximum thickness of the decorative layer 13 is thinner than the maximum thickness of the base layer 12. The thickness of the decorative layer 13 at the second outer edge 13a is thinner than the thickness at the outer edge of the covering portion 121 of the base layer 12.

[0041] As shown in FIG. 2, the second wavy portion 13b swaying in the inward and outward direction is formed on the second outer edge 13a of the decorative layer 13. The second wavy portion 13b is continuously provided along the second outer edge 13a (contour) of the decorative layer 13. The second wavy portion 13b is formed by droplets of ink forming the decorative layer 13. The second wavy portion 13b has a second deflection amount 13c in the inward and outward direction, which is a deflection amount in the inward and outward direction. The second deflection amount 13c indicates the degree of jaggedness of the second outer edge 13a. The second wavy portion 13b may be provided regularly or irregularly along the second outer edge 13a of the decorative layer 13. The second deflection amount 13c may be an average value. The second deflection amount 13c is smaller than the first deflection amount 12c. The second wavy portion 13b is a small and fine deflection, and the first wavy portion 12b is a large and coarse deflection compared to the second wavy portion 13b. Incidentally, a single intermediate layer or two or more intermediate layers may be provided between the base layer 12 and the decorative layer 13 .

[0042] The topcoat layer 14 is made of a transparent or semi-transparent synthetic resin such as epoxy, urethane, acrylic, acrylic silicone, etc. The topcoat layer 14 preferably covers the entire decorative layer 13, and more preferably covers the entire base layer 12.

[0043] As described above, the peripheral portion 122 of the base layer 12 protrudes outward from the outer edge of the decorative layer 13. Therefore, the outer edge, i.e., the contour, of the decorative layer 13 is less affected by the outer edge of the peripheral portion 122 of the base layer 12, and is sharp. The first corrugated portions 12b are larger than the second corrugated portions 13b. Therefore, since the outer edge of the decorative layer 13 is separated inward from the first corrugated portions 12b, the outer edge of the decorative layer 13 is less affected by the first corrugated portions 12b, and the outer edge of the decorative layer 13 can be formed sharp.
