Description

本発明は、外周面に装飾(模様)を施した管状体に関する。   The present invention relates to a tubular body having a decoration (pattern) on an outer peripheral surface.

通常、管状体である釣竿の外周面には様々な装飾が施されており、光輝性を有する外観を形成することがある。このような光輝性を有する外観は、例えば、表面に金属(アルミニウム、金、銀など)の蒸着層を形成することにより、或いは、顔料として光輝性を有する装飾粒子(金属箔、パール粒子など)を混入した塗料を、塗装、インクジェット印刷、スクリーン印刷等によって形成することが可能である。この場合、上記のような蒸着や、光輝性を有する粒子を含有した塗料では、光輝性が強すぎて外観が均一になってしまうことから、例えば、特許文献1に開示されているように、光輝性を抑制することが行われている。すなわち、光輝性を有する粒子に加え、遮光性のある粒子を混入することにより、反射光を弱めることができ、光輝色をある程度抑制した外観にすることが可能となる。   Usually, various decorations are given to the outer peripheral surface of the fishing rod which is a tubular body, and the appearance which has brilliancy may be formed. The appearance having such brilliancy is, for example, by forming a vapor deposition layer of metal (aluminum, gold, silver, etc.) on the surface, or decorative particles having brilliancy as a pigment (metal foil, pearl particles, etc.) It is possible to form the coating material mixed with by coating, ink jet printing, screen printing or the like. In this case, in the paint containing the above-described vapor deposition and particles having glitter, since the appearance becomes uniform because the glitter is too strong, for example, as disclosed in Patent Document 1, It is performed to suppress the glitter. That is, in addition to particles having glitter, mixing light-shielding particles can weaken the reflected light and make it possible to achieve an appearance in which the glitter color is suppressed to some extent.

特開2008−86241号JP 2008-86241 A

しかし、上記した従来技術では、光輝性のある粒子の中に遮光性のある粒子がランダムに分散することから、全体として光輝色を抑えた外観が得られるに過ぎず、また、アクセントのある外観とはならない。すなわち、上記した従来の管状体の外観模様は、光輝性のある粒子が遮光性のある粒子と共に深さ方向に亘って均一に分散した状態になることから、深みのある立体感に欠けるという問題がある。また、表面に何らかのアクセントを形成するに際しては、印刷等で表現しようとしても、それは平面的になってしまい、アクセント部分で深みのある(立体感のある)外観にはならない。   However, in the above-described conventional technology, since the light-shielding particles are randomly dispersed in the glittering particles, the appearance with only the glitter color being suppressed as a whole is obtained, and the accented appearance is obtained. It will not be. In other words, the appearance pattern of the conventional tubular body described above is a problem that the three-dimensional effect with the depth is lacking because the glittering particles are uniformly dispersed in the depth direction together with the light-shielding particles. There is. In addition, when an accent is formed on the surface, even if it is expressed by printing or the like, it becomes planar and does not have a deep (stereoscopic) appearance at the accent portion.

本発明は、上記した問題に着目してなされたものであり、外観にアクセントがある光輝性の模様を有し、かつ、そのアクセント部分で立体的で深みのある外観が得られる管状体を提供することを目的とする。   The present invention has been made by paying attention to the above-mentioned problems, and provides a tubular body having a lustrous pattern with an accent on the appearance and a three-dimensional and deep appearance at the accent portion. The purpose is to do.

上記した目的を達成するために、本発明に係る管状体は、繊維強化樹脂材によって表面にピッチ幅が0.5mm〜5.0mm、深さが20μm〜200μmの連続した凹凸部が形成され、前記凹凸部の表面に、顔料として平均径が60μm以下の偏光パール粒子を分散させた光輝性のある塗装を形成し、前記凹凸部に分散される偏光パール粒子を、凸部の表面領域よりも凹部内領域に多数分散させたことを特徴とする。   In order to achieve the above-described object, the tubular body according to the present invention has a continuous concavo-convex portion having a pitch width of 0.5 mm to 5.0 mm and a depth of 20 μm to 200 μm formed on the surface by a fiber reinforced resin material, On the surface of the concavo-convex portion, a brilliant coating in which polarized pearl particles having an average diameter of 60 μm or less are dispersed as a pigment is formed, and the polarized pearl particles dispersed in the concavo-convex portion are formed more than the surface region of the convex portion. It is characterized in that a large number are dispersed in the region in the recess.

上記した構成の管状体は、繊維強化樹脂材で形成され、その表面に、ピッチ幅が0.5mm〜5.0mm、深さが20μm〜200μmの連続した凹凸部が形成されている。このような大きさで連続的な凹凸部を表面に形成することで、外観は、連続した筋状の模様のアクセントが形成されることとなり、凹凸部が形成されていない表面とは印象が異なる(外観模様として区別化が図れる)外観を得ることが可能となる。また、このような筋状の模様において、顔料として平均径が60μm以下の偏光パール粒子を、凸部の表面領域よりも凹部内領域に多数分散させた(深い部分に沢山の偏光パール粒子が存在する)ことから、異なる方向で発色が異なる特性を有する偏光パール粒子からの反射光が、凹部の深いところでは明るい状態(光輝性が高く見る方向で色合いが変わる外観)となり、かつ凸部の高い位置では暗い状態(光輝性が低く見る方向で色合いが変わる外観)となる。すなわち、筋状の模様(アクセント模様)による凹凸感が外観として把握でき、また、凸部と凹部との境界部分が立体的となって(深みがある)、外観が向上した管状体となる。   The tubular body having the above-described configuration is formed of a fiber reinforced resin material, and a continuous uneven portion having a pitch width of 0.5 mm to 5.0 mm and a depth of 20 μm to 200 μm is formed on the surface thereof. By forming continuous irregularities on the surface in such a size, the appearance will be accented with a continuous streak pattern, and the impression will be different from the surface where the irregularities are not formed It is possible to obtain an appearance (which can be differentiated as an appearance pattern). Further, in such a streak pattern, a large number of polarized pearl particles having an average diameter of 60 μm or less as a pigment were dispersed in the recessed area rather than the surface area of the projected part (a large number of polarized pearl particles exist in the deep part). Therefore, the reflected light from the polarized pearl particles having different color development properties in different directions becomes bright in the deep part of the concave part (appearance that changes its color depending on the viewing direction with high glitter) and has a high convex part. The position is dark (appearance is low in brightness and changes in color in the viewing direction). That is, the unevenness due to the streak pattern (accent pattern) can be grasped as the appearance, and the boundary portion between the convex portion and the concave portion becomes three-dimensional (has a depth), and the tubular body has an improved appearance.

なお、本発明において、顔料として偏光パール粒子を用いたのは、光輝性がある通常の金属箔では、光の反射が均一になる傾向が強いとともに同様な色調の反射光となり、見る方向が変わっても大きな外観変化が得られず、他の外観模様との区別化が十分に図れないことによる。すなわち、偏光パール粒子を用いれば、光輝性のあるパール光沢が得られるとともに、見る方向によって色調の変化が得られ、外観が著しく向上できるようになる。また、上記した大きさの粒子径を、上記した大きさの凹凸部の表面に、凹部内が多くなるように分散させることで、凹凸部によるアクセント(縞模様)を際立たせることができ、かつ凹部部分で深みのある立体的な外観が得られるようになる。   In the present invention, the use of polarized pearl particles as the pigment is that the normal metallic foil with glitter has a strong tendency to make the light reflection uniform and the reflected light has the same color tone, and the viewing direction changes. However, a large change in appearance cannot be obtained, and it cannot be sufficiently distinguished from other appearance patterns. That is, if the polarized pearl particles are used, a lustrous pearly luster can be obtained, a change in color tone can be obtained depending on the viewing direction, and the appearance can be remarkably improved. Further, by dispersing the particle size of the above-described size on the surface of the concavo-convex portion of the above-described size so that the inside of the concavo-convex portion is increased, the accent (stripe pattern) due to the concavo-convex portion can be emphasized, and A deep three-dimensional appearance can be obtained at the recessed portion.

本発明によれば、外観にアクセントがある光輝性の模様を有し、かつ、そのアクセント部分で立体的で深みのある外観が得られる管状体が得られる。   ADVANTAGE OF THE INVENTION According to this invention, the tubular body which has a lustrous pattern with an accent in an external appearance, and the three-dimensional and deep external appearance is obtained in the accent part is obtained.

以下、図面を参照しながら、本発明に係る装飾層を備えた管状体の一実施形態について説明する。   Hereinafter, an embodiment of a tubular body provided with a decorative layer according to the present invention will be described with reference to the drawings.

図1に示すように、本発明は、管状体として釣竿に適用することが可能である。図示のように、釣竿1は、複数の管状体としての竿杆、具体的には、グリップ3aを有する元竿3と、中竿5と、穂先竿7とによって構成される。この場合、各竿杆3,5,7は、振出し式または並継ぎ式に構成されており、各竿杆3,5,7を構成する管状体本体(素材本体10;図4参照)は、公知のように、強化繊維に合成樹脂を含浸した繊維強化プリプレグをマンドルに巻回し、加熱・焼成・脱芯など常法に従って形成されている。また、各竿杆3,5,7の表面は、後述するような凹凸状態にされて模様20が形成されている。
以下、竿杆(元竿)3を例示して、竿杆表面に形成される模様20について説明する。
As shown in FIG. 1, the present invention can be applied to a fishing rod as a tubular body. As shown in the figure, the fishing rod 1 is composed of a plurality of rods as tubular bodies, specifically, a main rod 3 having a grip 3a, a middle rod 5, and a tip rod 7. In this case, each of the flanges 3, 5, and 7 is configured as a swing-out type or a splicing type. As is well known, a fiber reinforced prepreg in which a reinforcing fiber is impregnated with a synthetic resin is wound around a mandrel, and is formed according to a conventional method such as heating, firing, and decentering. Further, the surface of each of the ridges 3, 5, and 7 is formed in a concavo-convex state as will be described later, and a pattern 20 is formed.
Hereinafter, the pattern 20 formed on the surface of the heel will be described by exemplifying the heel (general heel) 3.

竿杆3の表面(素材本体10の表面10a)には、ピッチ幅Wが0.5mm〜2.0mm、深さHが20μm〜200μmの連続した凹凸部21が形成されている。本実施形態では、凹凸部21は、軸長方向に沿って連続的に形成されており、図4に示すように、前記ピッチ幅Wは、凹凸部21が連続した方向に沿って断面視した際、隣接する凸部21aの中心位置同士の距離によって定義され、前記深さDについては、表面10aに対する凸部21aの高さによって定義される。このため、竿杆3の表面は、連続形成される凹凸部によって、軸長方向に沿って輪帯状の縞模様が連続的に形成されるようになる。   On the surface of the bowl 3 (surface 10a of the material main body 10), a continuous uneven portion 21 having a pitch width W of 0.5 mm to 2.0 mm and a depth H of 20 μm to 200 μm is formed. In the present embodiment, the concavo-convex portion 21 is continuously formed along the axial length direction, and as shown in FIG. 4, the pitch width W is viewed in cross-section along the direction in which the concavo-convex portion 21 is continuous. At this time, it is defined by the distance between the center positions of the adjacent convex portions 21a, and the depth D is defined by the height of the convex portion 21a with respect to the surface 10a. For this reason, a ring-shaped striped pattern is continuously formed on the surface of the flange 3 along the axial length direction by the uneven portions that are continuously formed.

このような凹凸部21は、例えば、竿杆(管状体)成形時に、マンドレルに巻回されるプリプレグシートによって形成することが可能である。具体的には、例えば、図2に示すように、多数の繊維を束状にすることで構成された強化繊維12a,12b,12cを3軸方向に編成したプリプレグシート12を表面に巻回することで形成することが可能である。この場合、各繊維の径は、直径が3〜10μmとしたものが用いられており、このようなプリプレグシート12を最外層に巻回することにより、容易に上記したピッチ幅W、深さDの凹凸部21を竿杆表面に形成することが可能となる。   Such a concavo-convex portion 21 can be formed by, for example, a prepreg sheet wound around a mandrel when forming a ridge (tubular body). Specifically, for example, as shown in FIG. 2, a prepreg sheet 12 in which reinforcing fibers 12a, 12b, and 12c configured by bundling a large number of fibers are knitted in three axial directions is wound around the surface. Can be formed. In this case, the diameter of each fiber is 3 to 10 μm, and the above-described pitch width W and depth D can be easily obtained by winding such a prepreg sheet 12 around the outermost layer. It becomes possible to form the uneven portion 21 on the heel surface.

上記したプリプレグシート12をマンドレルに巻回するに際しては、1つの平行状態にある強化繊維(図では強化繊維12aとなる)を軸長方向Xに対して直交するY方向に沿うように巻回することで、図4に示すような凹凸部21を軸長方向に沿って形成することが可能となる。すなわち、編成された強化繊維の隣接する強化繊維12a間に、重なった強化繊維12b,12cが入り込むことによって、1つの凸部21aが形成されるようになる。   When the above-described prepreg sheet 12 is wound around a mandrel, one reinforcing fiber (in the figure, the reinforcing fiber 12a) in a parallel state is wound along the Y direction orthogonal to the axial length direction X. Thus, the uneven portion 21 as shown in FIG. 4 can be formed along the axial length direction. In other words, the overlapping reinforcing fibers 12b and 12c enter between the adjacent reinforcing fibers 12a of the knitted reinforcing fibers so that one convex portion 21a is formed.

本発明において、管状体の表面に形成される凹凸部21に関し、ピッチ幅Wを0.5mm〜5.0mmとし、かつ、深さHを20μm〜200μmに特定したのは、上記したような3軸プリプレグシート12を最外層となるように巻回した場合、容易に連続した凹凸部を形成することができるとともに、そのように形成される凹凸部21は、竿杆表面に形成されるアクセント(軸長方向に沿った連続的な縞模様となる)として、一般的な外観模様と区別化でき、外観的にも良い印象が与えることができることに基づく。また、後述するような大きさの偏光パール粒子を顔料として用いた場合に、凹凸部の大きさとの関係で立体的になった縞模様となり、好ましい外観が得られたことによる。   In the present invention, regarding the uneven portion 21 formed on the surface of the tubular body, the pitch width W is set to 0.5 mm to 5.0 mm and the depth H is specified to 20 μm to 200 μm as described above 3 When the shaft prepreg sheet 12 is wound so as to be the outermost layer, a continuous concavo-convex portion can be easily formed, and the concavo-convex portion 21 formed as such is an accent ( This is based on the fact that it can be distinguished from a general appearance pattern and can give a good impression in terms of appearance as a continuous stripe pattern along the axial length direction). In addition, when polarized pearl particles having a size as described later are used as a pigment, a three-dimensional striped pattern is obtained in relation to the size of the concavo-convex portion, and a preferable appearance is obtained.

なお、凹凸部21については、上記したような構成のプリプレグシート12を巻回する以外にも、例えば、表面に緊締テープを密巻きし、剥離することによって形成しても良いし、表面を研磨することで形成しても良い。   In addition to winding the prepreg sheet 12 having the above-described configuration, the concavo-convex portion 21 may be formed, for example, by tightly winding a fastening tape on the surface and peeling it, or polishing the surface. You may form by doing.

上記したように形成された凹凸部21に対しては塗装が施される。この塗装に用いられる塗料30は、所定の合成樹脂(例えばアクリル系樹脂、エポキシ系樹脂、ウレタン系樹脂、ビニール系樹脂等)31に、所望の大きさの偏光パール顔料(粒子)32を均一に混入したもので構成され、これにより光輝性のある外観にできるとともに、見た方向で色調が変わる(単色ではない)外観にすることが可能となる。   The uneven portion 21 formed as described above is painted. The coating material 30 used for this coating is a predetermined synthetic resin (for example, an acrylic resin, an epoxy resin, a urethane resin, a vinyl resin, etc.) 31 and a polarizing pearl pigment (particle) 32 of a desired size is uniformly applied. It is made up of mixed materials, and this makes it possible to have a lustrous appearance, and to change the color tone in the direction seen (not a single color).

混入される偏光パール顔料32は、図3に概略で示すように、コア部材32aとして雲母(マイカ)が用いられ、その表面に、雲母に対して屈折率が高い酸化チタン、酸化鉄などの金属酸化物32b,32cを複数層、被着することで構成される。すなわち、偏光パール顔料は、コア部材32aに対して複数の高屈折率の外面被膜層32b,32cが重ねて被着されることから、単なる金属箔やパール顔料と比較すると、入射光、反射光の屈折する領域が増え、この結果、層間の境界部分での光干渉効果が高まって、光の当たり具合や見る位置によって、メタリック調の光沢を発現しつつ見る方向によって異なる色彩の外観が得られる。   As schematically shown in FIG. 3, the mixed polarized pearl pigment 32 uses mica (mica) as the core member 32a, and has a metal such as titanium oxide or iron oxide having a high refractive index with respect to mica on the surface. It is configured by depositing a plurality of layers of oxides 32b and 32c. That is, the polarized pearl pigment has a plurality of high-refractive-index outer surface coating layers 32b and 32c applied to the core member 32a so that it is incident light and reflected light as compared with a simple metal foil or pearl pigment. As a result, the light interference effect at the boundary between layers increases, and the appearance of a color that varies depending on the viewing direction can be obtained while exhibiting a metallic luster depending on the light hitting position and the viewing position. .

上記のような偏光パール顔料32は、所定の合成樹脂に所望の密度で混入されるが、その大きさ(最大となる径L)を考慮した場合、分散される偏光パール顔料の平均径が、60μm以下のものが用いられる。これは、混入される偏光パール顔料の平均径が、60μmよりも大きくなってしまうと、偏光パール粒子が合成樹脂中に所望の密度で、均一に分散できなくなってしまい、凹凸部21に塗布した際、偏光パール粒子が密集する領域や存在しない領域が点在する傾向となり、凸部領域と凹部領域において、以下のように相対的に凹部内の密度が高い状態にならず、深みのある外観が得られなくなってしまうからである。   The polarized pearl pigment 32 as described above is mixed in a predetermined synthetic resin at a desired density. However, when considering the size (maximum diameter L), the average diameter of the dispersed pearl pigment to be dispersed is The thing of 60 micrometers or less is used. This is because when the average diameter of the mixed polarized pearl pigment becomes larger than 60 μm, the polarized pearl particles cannot be uniformly dispersed at a desired density in the synthetic resin, and are applied to the uneven portion 21. At the time, the areas where the polarized pearl particles are densely populated or the areas where the pearl particles are not present tend to be scattered, and in the convex region and the concave region, the density in the concave portion is not relatively high as described below, and the appearance is deep. It is because it becomes impossible to obtain.

上記したような塗料30は、凹凸部21の表面に対して、その凹凸部に分散される偏光パール粒子32の割合が、凸部21aの表面領域よりも凹部21b内の領域に多数分散するように塗装される。具体的に、このような状態については、凹凸部21が形成されている方向に沿ってシゴキ塗装を施すことにより形成することが可能である。すなわち、上記したような径の顔料を含んだ塗料によれば、軸方向にしごくように凹凸部に付着させることで、偏光パール顔料は、凹部21bに多数入りこむことができ、図4に示すように、凹凸部21の深い部分(凹部の領域)では、頂部の領域と比較して、相対的に沢山の偏光パール粒子32が存在するように被着することが可能となる。   In the coating material 30 as described above, the ratio of the polarized pearl particles 32 dispersed in the concavo-convex portion to the surface of the concavo-convex portion 21 is more dispersed in the region in the concave portion 21b than in the surface region of the convex portion 21a. Painted on. Specifically, such a state can be formed by applying a squeeze coating along the direction in which the uneven portion 21 is formed. That is, according to the paint containing the pigment having the diameter as described above, a large number of polarized pearl pigments can penetrate into the concave portion 21b by adhering to the concave and convex portions in the axial direction, as shown in FIG. In addition, it is possible to deposit so that a relatively large number of polarized pearl particles 32 are present in the deep part of the concavo-convex part 21 (recessed part region) compared to the top region.

凹凸部21に対してこのような塗装を施すことで、異なる方向から見た際、発色が異なる特性を有する偏光パール粒子32からの反射光が、凹部21bの深いところでは明るい(薄い)状態になるとともに、凸部21aの高い位置では暗い(濃い)状態となり、凹部21bの領域では、明るい状態で色彩変化を多くすることができるようになる。また、凹凸部によって形成される筋状の模様(アクセント模様)による凹凸感が外観として把握できるようになり、凸部21aから凹部21bに至る境界領域が立体的となって(深みがある)、外観の向上が図れるようになる。   By applying such a coating to the concavo-convex portion 21, the reflected light from the polarized pearl particles 32 having different color development properties when viewed from different directions is bright (thin) in the deep portion of the concave portion 21b. In addition, a dark (dark) state is obtained at a high position of the convex portion 21a, and a color change can be increased in a bright state in the region of the concave portion 21b. In addition, the impression of unevenness due to the streaky pattern (accent pattern) formed by the uneven portions can be grasped as the appearance, and the boundary region from the convex portion 21a to the concave portion 21b becomes three-dimensional (there is depth). Appearance can be improved.

ここで、図5を参照して、上記したように形成される外観模様について説明する。
(a)は、上記した構成で得られる管状体の表面を撮影したものであり、(b)は、比較対象として、同じ塗料を、凹凸部を形成していない表面に同様なシゴキ塗装によって被着した状態の管状体の表面を撮影したものである。なお、両写真において写り込んでいるドット状の白色部分は、撮影時のフラッシュによって偏光パール顔料部分で瞬間的に反射した領域であり、実際に目視した際には、このようなドット状の白色は認識することはできない。
Here, the appearance pattern formed as described above will be described with reference to FIG.
(A) is a photograph of the surface of a tubular body obtained with the above-described configuration. It is a photograph of the surface of the tubular body worn. In addition, the dot-like white part that is reflected in both photographs is the area that is instantaneously reflected by the polarized pearl pigment part by the flash at the time of shooting. Can not recognize.

管状体表面に、上記したような連続的な凹凸部21が形成されていることで、凹部の深いところでは、多数の偏光パール顔料が密集して反射がランダムな状態となって明るい状態(光輝性がある薄い色;写真では薄い赤色部分)となる。また、凸部の高い位置では、少ない量の偏光パール粒子が分散(図5(b)に示すような状態で分散)しており、この領域では光輝性が低くなって暗い状態(光輝性がある濃い色;写真では黒に近い赤色部分)となる。すなわち、凸部の高い位置から低い位置(凹部)に移行するに当たり、光輝性が低い状態から高い状態に変化することから、色調が変化する縞状になったアクセント模様が得られるようになる。また、凹部には多数の偏光パール粒子が存在しているため、見る角度による色調の変化も大きくなる。   By forming the continuous uneven portion 21 as described above on the surface of the tubular body, in the deep portion of the recess, a large number of polarized pearl pigments are concentrated and the reflection is in a random state (brightness) Light color; light red part in the photo). In addition, a small amount of polarized pearl particles is dispersed (dispersed in a state as shown in FIG. 5B) at a high position of the convex portion. In this region, the glitter is low and the glitter (the glitter is low). Some dark colors; red in the picture are close to black). That is, when shifting from a high position of the convex portion to a low position (concave portion), the glittering property changes from a low state to a high state, so that a striped accent pattern with a changing color tone can be obtained. In addition, since a large number of polarized pearl particles are present in the concave portion, the color tone changes greatly depending on the viewing angle.

これに対して、凹凸部が形成されていない表面に、同様な塗料を同様な方法で被着しても、図5(b)に示すように、単に、全体的に光輝性のある反射光が得られるに留まり、アクセント模様による色調の変化は得られず、深みのある立体的な外観も得ることはできない。   On the other hand, even if the same paint is applied to the surface on which the uneven portion is not formed by the same method, as shown in FIG. However, it is not possible to obtain a deep three-dimensional appearance.

また、上記のような偏光パール粒子32を含んだ塗装の表面には、保護層を形成することが好ましい。このような保護層は、例えば、エポキシ、ウレタン、アクリル、アクリルシリコン、シリコン等の合成樹脂を吹き付け、シゴキ、刷毛塗り等によって被着することができ、塗装表面を平滑化することができるようになる。また、保護層は、顔料等を混入して着色したものであっても良い。   Moreover, it is preferable to form a protective layer on the surface of the coating containing the polarized pearl particles 32 as described above. Such a protective layer can be applied, for example, by spraying synthetic resin such as epoxy, urethane, acrylic, acrylic silicon, silicon, squeeze, brushing, etc., so that the painted surface can be smoothed. Become. Further, the protective layer may be colored by mixing a pigment or the like.

さらに、上記した保護層については、図4に示すように複数層形成しても良い(保護層40,41)。このように、保護層を複数層形成することで、層間の境界部分で屈折率の変化が得られ、さらに外観に変化を持たせることが可能となる。   Further, the protective layer described above may be formed in a plurality of layers as shown in FIG. 4 (protective layers 40 and 41). In this way, by forming a plurality of protective layers, a change in refractive index can be obtained at the boundary between the layers, and the appearance can be further changed.

以上、本発明の実施形態について説明したが、本発明は、上記した実施形態に限定されることはなく、その要旨を逸脱しない範囲で種々変形して実施することが可能である。   As mentioned above, although embodiment of this invention was described, this invention is not limited to above-described embodiment, It is possible to implement in various deformation | transformation in the range which does not deviate from the summary.

上記した塗料は、顔料である偏光パール粒子のコア部材を雲母としているが、単に光輝性のある外観するのであれば、コア部材としてアルミニウム、金、銀などを用いて金属光沢の光輝性にすることも可能である。また、管状体の表面に形成される凹凸部については軸長方向に沿って連続的に形成したが、周方向に亘って連続するように形成しても良く、そのような凹凸部は、管状体の一部に形成しても良い。   The coating material described above uses mica as the core member of the polarized pearl particles, which are pigments, but if it only has a brilliant appearance, it is made to have a metallic luster by using aluminum, gold, silver or the like as the core member. It is also possible. Moreover, although the uneven | corrugated | grooved part formed in the surface of a tubular body was formed continuously along the axial length direction, you may form so that it may continue over the circumferential direction, and such an uneven | corrugated | grooved part is tubular. It may be formed on a part of the body.
