DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a tubular body having a decorative layer according to the present invention will be described with reference to the drawings.

Fig. 1 shows a fishing rod 1 as an example of a tubular body of the present invention. As shown in the drawing, the fishing rod 1 has a rod 3 as a plurality of tubular bodies, specifically, a grip 3a, a first heavy rod 5, a second heavy rod 7 And a supporter 9 having a fishing line fastening hole 9a. In this case, each of the poles 3, 5 and 7 is constituted by an advancing type or a bottle system and is constituted by a tubular body constituting each of the poles 3, 5 and 7 ) Is formed by winding a fiber-reinforced prepreg impregnated with a synthetic resin on the reinforcing fibers (or may be formed of a metal such as steel), and the decorative portions A are formed on the respective poles 3, 5,

The ornamental portion A is formed by inkjet printing as will be described later and has a line shape A1 extending linearly over at least a part (the entire circumference in the present embodiment) in the circumferential direction of the poles 3, 5, (In this embodiment, a plurality of regions adjacent to each other in a lattice shape) extending in a peripheral direction of the poles 3, 5 and 7 (in this embodiment, the entire circumference) A coloring layer having a color formed by superimposing a plurality of coloring materials in a dot shape) A2 and a stripe shape A3. Here, the barrel shape A3 refers to a barrel portion A3 '(for example, extending linearly in the axial direction and having a predetermined width in the circumferential direction) including an area thinner than other portions of the ink, And the density of the tip portion A3 'may change stepwise along the circumferential direction or the axial direction, for example. Alternatively, the tip portion A3 'may be such that the combination of the colors of the ink gradually changes.

As shown in FIG. 3, the decorating portions A, A2 and A3 include a decorative layer 25 formed on a work body 20 constituting each pole 3, 5 and 7. Specifically, the decorative layer 25 includes a first base layer 30 (e.g., having a thickness of 5 to 20 占 퐉) 30 formed on the work body 20, and a first base layer A second underlying layer 31 (e.g., having a thickness of 5 to 20 占 퐉), a colored layer 32 (e.g., having a thickness of 10 to 60 占 퐉) formed on the second base layer 31, And a transparent protective layer 33 (for example, having a thickness of 15 to 25 mu m) formed on the colored layer 32. [

The first base layer 30 is provided for smoothing the outer surface of the work body 20 and is made of synthetic resin such as epoxy, urethane, acrylic, acrylic silicone, silicone, etc., and is sprayed, Painting, brush coating, and the like. The first base layer 30 may be colored by mixing pigments or the like.

The second base layer 31 is for the purpose of concealing the base, adjusting the lightness and color tone of the colored layer 32, and includes a light reflecting layer and a white layer. The light reflection layer is a layer in which a plurality of particles having a light-like property (hereinafter referred to as light-weight particles) are desired in a material having a light-like property, for example, a predetermined synthetic resin (acrylic resin, epoxy resin, vinyl resin or the like) It can be formed by coating with a uniform and uniformly mixed density.

The luminescent particles to be mixed in the predetermined synthetic resin are selected from the group consisting of Al, Cu, Ag, Mg, In, Cr, Si, Ni, Ti, Au, Rh, Pt, It is possible to use materials. In this case, the size of each particle is preferably set to 2 mu m or less, preferably 0.3 mu m to 1 mu m, and the thickness is preferably 1 mu m or less, preferably 0.03 mu m to 0.5 mu m. In other words, if the size and thickness of the particle body are set outside this range, it becomes impossible to uniformly arrange the light-bright particles in the synthetic resin at a desired density and at the same time, the boundary of the light- The uniformity of the appearance of lightness can not be exerted.

Such a method for forming a light-fast particle can be achieved by, for example, depositing or sputtering the metal material on a film-shaped support substrate containing Teflon (registered trademark) or a silicone resin to form a metal layer, And then pulverized. It is preferable that a plurality of the light-fastening particles thus formed are uniformly arranged at a density sufficient to exhibit their lightness and to produce a desired color. Concretely, it is preferable that the density of the light-fastening particles incorporated in the synthetic resin is set so that the number of the light-fastening particles per unit area is 50,000 to 20,000,000 / mm2. According to the light reflecting layer formed in this manner, it becomes possible to present a bright appearance that is uniform and colored with a desired color.

In addition to the above-described configuration, the light reflecting layer may be formed by a single piece of metal such as gold, silver, copper, aluminum, chromium, cobalt, nickel, iron or zinc, , It can be formed by mixing it with a small amount of synthetic resin, diluting it with a large amount of solvent, spraying it by gun spray coating or the like, and then removing (volatilizing) the solvent. In addition, it is possible to form various appearance by changing the size, combination, etc. of particles such as metal pieces and pigments.

Or, in addition to the above-described configuration, the light reflection layer, Cr, Ni, Ti, Al, Ag, the ceramics of the alloys, TiO _2, SiC, etc. of metal, TiN, such as TiCN, CrN, Fe-Cr-Ni, such as Be It can be formed as a main material, and thus it is possible to improve the appearance. The light reflection layer using such a metal or ceramics can be formed by dry plating such as physical vapor deposition such as ion plating, sputtering or vapor deposition, chemical vapor deposition, vacuum deposition, or wet plating. The white layer may be formed by coating a predetermined synthetic resin, or may be formed by inkjet printing. In this case, it is preferable that the undergarment is concealed and the brightness of the colored layer is easily adjusted.

The protective layer 33 formed on the colored layer 32 is made of transparent or semitransparent synthetic resin such as epoxy, urethane, acrylic, or acrylic silicone.

Next, a specific structure and a forming method of the colored layer 32 formed on the second base layer 31 will be described.

4, the colored layer 32 has a plurality of regions 40A and 40B each having a polygonal shape (square in this embodiment), and these regions 40A , And 40B are formed by overlapping a plurality of coloring materials in a dot shape, and dots in each area are printed by an inkjet printer (not shown). The coloring layer 32 may be formed, for example, by adding a coloring material such as a pigment or a dye to a transparent or semitransparent synthetic resin such as epoxy or urethane to contain a curing agent. In this embodiment, An ultraviolet curing type ink which is cured by irradiation with ultraviolet rays which is a curing light ray is used. As the photo-curable ink, an acrylic-based or epoxy-cationic-based ink or the like is used. In particular, an ultraviolet curable ink containing a sensitizer mixed with a polyfunctional monomer and an acrylate oligomer is used. In such an ink, a sensitizer forms a radical and causes a chain reaction of an oligomer and a monomer. The ink may be a thermosetting type, a solvent (water or organic material) drying type, or a two-liquid reaction type.

The print pattern of the present embodiment is a print pattern in which the regions 40A and 40B are formed in a rectangular shape (square shape) having the same size and are adjacent to each other, The droplet is controlled to be ejected. That is, the print head is configured to make the coloring material of cyan, magenta, yellow, and black systems into a liquid droplet shape through a plurality of jet nozzles and to control the color of the material main body 20 (second base layer 31) As shown in FIG.

As shown in Figs. 2 and 4, the coloring materials injected into the respective regions 40A and 40B are controlled so that the densities of the coloring materials of the adjacent portions are different from each other. In the region 40A, (The formation density is large and the concealability is large), and in the region 40B adjacent thereto, the amount of dot to be ejected is smaller than that (formation density is small and concealability is small). That is, in the colored layer 32, the area 40A having a large dot amount to be ejected and the area 40B having a small dot amount to be ejected are alternately arranged, and in the state of being divided by a boundary to be described later, It forms a mesh shape.

Further, the dots formed as described above can be controlled to be injected while overlapping each time the print head is reciprocated along the scanning direction (for example, the axial direction X of the poles (3, 5, 7)) Therefore, the thickness of the region 40A can be increased, and the thickness of the region 40B can be reduced to make the surface irregular (the height can be changed in the adjacent region) in the region 40A. And the appearance that senses the surface irregularities can be made possible.

In the present embodiment, the polygonal regions 40A and 40B are all formed in the same rectangular shape (one side is 0.5 to 10 mm square), and the colored layer 32 And has a plurality of straight-line boundaries 41, 42 between each adjacent region. That is, the boundaries 41 and 42 are formed substantially parallel to each other and intersect with each other in the orthogonal direction to divide the regions 40A and 40B. Thus, a plurality of regions (square regions 40A, 40B) to form a lattice shape.

According to the coloring layer 32 constituted as described above, it is possible to express a mesh shape by the adjacent polygonal areas 40A and 40B. In this case, each of the regions 40A and 40B is formed in the same square shape and has a lattice shape, and the boundaries 41 and 42 are all substantially parallel and cross each other linearly, It can express precise sense like reinforcement fiber. Further, adjacent regions 40A and 40B have different gradations (densities) of the coloring material superimposed in the dot shape, that is, the coloring material, so that natural gradation can be exhibited and a three-dimensional effect can be exhibited.

In addition, when the outer appearance such as the above-mentioned reinforcing fiber is formed by screen printing, positioning and the like are very difficult, and the appearance of a planar appearance tends to be obtained. However, by using inkjet printing, It is possible to easily form a knitted outer appearance.

In this case, the rectangular regions 60a1 and 60b1 in which the coloring material is superimposed in a dot shape are arranged such that the density gradually changes linearly along the axial direction (X direction, Y direction) ) Dots are attached, and they are all formed so as to change in uniform density in the axial direction. The rectangular regions 60a1 and 60a2 and the rectangular regions 60b1 and 60b2 are divided by a plurality of adjacent straight line boundaries 61 and a straight line boundary 62 orthogonal thereto. Thereby forming a shape that can be visually recognized as a mesh shape.
