Description

【０００１】
【発明の属する技術分野】
本発明は、プラスチックや金属、木材、ガラス、セラミックス等で成る基材の表面に塗装を施して、その塗装面（塗膜表面）の色やテクスチャーで外観を美麗化した表面加飾品とその加飾方法に関する。
【０００２】
【従来の技術】
塗装は、一般に、防錆、防腐、耐候性向上などの保護効果と、表面硬度や耐熱性の向上あるいは電気絶縁性や導電性の付与などの物性・機能性の改良効果と、塗装面のもつ色やテクスチャー（肌合い）で外観を美麗化する装飾効果とを主たる目的として行われ、特に、金属製品や木材製品にとっては、その表面に所望の色やテクスチャーを付ける最も重要な加飾法の一つである。
【０００３】
一方、成形材料そのものを所望の色に着色し、成形金型で凹凸等のテクスチャーを付けることができるプラスチック製品にとっては、塗装は、本来あまり必要のないものとされており、装飾目的の塗装も、金属製品や木材製品が必要とする表面の仕上げ（外観の美麗化）としてではなく、模様やマークなどを印刷する代替手段としての塗装が主であった。
【０００４】
しかし、最近は、プラスチック製品の利用範囲が著しく拡大し、家電製品やＯＡ機器等の電子機器類のみならず、自動車の内装部品や外装部品などにも、軽量化や成形性の良さによるコストダウンが図れるプラスチック成形品が多用されており、これに伴って、外観の美麗化という装飾効果だけを目的としたプラスチック製品の塗装需要が著しく増大している。
【０００５】
特に、自動車の内装部品に関しては、車内に快適な居住空間を創造する外観品質と、ユーザーの個性化指向を満足させる斬新性とを兼ね備えた高級感ある加飾塗装が求められている。
【０００６】
【発明が解決しようとする課題】
しかしながら、塗装の場合は、使用する塗料の種類や色数が限られ、塗料の塗り方にも制約があるため、印刷のように多数の色やモチーフを組み合わせて複雑な図柄を構成することなどはできず、塗膜に従来にない斬新で高級感のある色やテクスチャーを付与するのは容易ではない。
【０００７】
殊に、塗装機で塗料を噴霧する機械塗装の場合は、スチップル塗装の如く刷毛やロールで塗膜を波立たせて立体感を付与することもできず、テクスチャーのバリエーションが限られている。
【０００８】
また、建物の天井や壁等であれば、スチップル塗装は勿論、セメントの粉末に粗目の石灰粉や珪石粉等の骨材が混入されたセメントリシン塗料等を口径３〜５mmのモルタルガンで吹きつけて凹凸を付ける砂まき塗装なども行えるが、これらの塗装は、塗膜のテクスチャーが粗雑すぎて、自動車や家電製品、電子機器等の工業製品の表面仕上げには全く適用できない。
【０００９】
なお、工業製品の表面にテクスチャーを付ける塗装手段としては、シリコン樹脂が配合された塗料をスプレーガンで吹きつけてハンマーで叩いたような立体模様を平面の状態で現出させるハンマートーン塗装や、中塗り塗膜にクラッキングエナメルを吹きつけてその塗膜にひび割れを生じさせるクラッキング塗装や、塗膜の表面に細かい縮み皺を生じさせるチリメン塗装等があるが、チリメン塗装は、古くから顕微鏡その他の光学機械や金属製ロッカー等の表面仕上げに用いられており、また、ハンマートーン塗装も、工作機械等の表面仕上げとしてありふれたもので、斬新性に欠けると同時に、高級感も欠いている。
【００１０】
また、その他には、アルミ粉やアルミフレーク等の光輝材を配合した塗料で金属感のある輝きを現出させるメタリック塗装や、パール液を配合した塗料で真珠もしくは虹色の輝きを現出させるパール塗装もあるが、塗膜全体が一様に金属光沢や真珠光沢を放つだけの単調なテクスチャーは、斬新性に欠け、工業製品によっては却って高級感を損なうおそれがある。
【００１１】
そこで本発明は、鱗片状の光輝材が顔料として配合されたメタリック塗料やパール塗料等の光輝性塗料を使用し、従来のメタリック塗装やパール塗装とは異なる手法によって、斬新で且つ高級感があり、工業製品の表面仕上げにも最適な色とテクスチャーを付与することを技術的課題としている。
【００１２】
【課題を解決するための手段】
上記の課題を解決するために、本発明は、表面の一部もしくは全体が鱗片状の光輝材を顔料とする光輝性塗料の塗膜で加飾された表面加飾品であって、溶剤の希釈比が相対的に大きい光輝性塗料を粗粒化した低粘度塗料粒子と、溶剤の希釈比が相対的に小さい光輝性塗料を粗粒化した高粘度塗料粒子が、互いに入り混じった状態で塗着されて、前記低粘度塗料粒子が乾燥固化して成る明輝部と、前記高粘度塗料粒子が乾燥固化して成る暗輝部とが混在した斑模様を現出する塗膜が形成され、当該塗膜の上に、任意の図柄を呈するインキ模様が印刷されていることを特徴とする。
【００１３】
本発明の表面加飾品は、その表面に入り混じって塗着された光輝性塗料の低粘度塗料粒子と高粘度塗料粒子が、溶剤の蒸発により体積が収縮して乾燥固化する過程において、溶剤の希釈比が大きい低粘度塗料粒子は、体積収縮率が大きいために、その体積収縮作用で、塗料粒子中に含まれた鱗片状の光輝材が塗着面と平行な向きになるように流動せられて、鱗のように水平に並んだ状態となるので、光の反射率が大きく、塗着面の隠蔽力も大きいので、キラキラと明るく輝いた明輝部となる。
【００１４】
一方、溶剤の希釈比が小さい高粘度塗料粒子は、体積収縮率が小さいために、体積収縮の際に鱗片状の光輝材が流動する度合いも小さく、塗着面と平行な向きになるものが少ないので、光の反射率と塗着面の隠蔽力が小さく、暗い輝きの暗輝部となる。
【００１５】
これにより、光輝性塗料の低粘度塗料粒子と高粘度塗料粒子が入り混じって塗着された塗膜は、明輝部と暗輝部が混在した斬新な斑模様を現出すると同時に、明輝部と暗輝部の輝き度合いや光の反射具合が、観る角度によって各々微妙に変化し、その変化と明暗のコントラストとが相まって、見掛けの凹凸感を平面の状態で現出し、外観に深みや高級感を醸し出す。
【００１６】
更に、その塗膜の上に、任意の図柄を呈するインキ模様が印刷されることにより、当該インキ模様と、明輝部と暗輝部が混在した斑模様で成る地模様とが重なり合った合成模様が現出し、より一層深みや高級感のある外観を呈する。
【００１７】
【発明の実施の形態】
以下、本発明の実施形態を図面によって具体的に説明する。
図１は本発明による表面加飾品の一例を示す断面図、図２は表面加飾品の表面に形成した光輝性塗料の塗膜の外観を示す平面図、図３は光輝性塗料の塗装方法の一例を示す概略図、図４は光輝性塗料の塗膜の上に印刷されるインキ模様の一例を示す平面図、図５はそのインキ模様が印刷された表面加飾品の外観を示す平面図、図６はインキ模様の変更例を示す平面図、図７はそのインキ模様が印刷された表面加飾品の外観を示す平面図、図８は表面加飾品の変形例を示す断面図である。
【００１８】
本発明の表面加飾品は、例えば図１に示すように、プラスチックや金属等の塗装可能な材料で成る基材１の表面に、素地着色塗料でベースコート２が施され、そのベースコート２の上に、鱗片状の光輝材３を顔料とする光輝性塗料の塗膜４が形成され、当該塗膜４の上に、水圧転写によって、任意の図柄を呈するインキ模様５が印刷され、更にその上から、無色透明もしくは着色透明のクリア塗料によって表面保護層となるクリアコート６が施されている。
【００１９】
塗膜４を形成する光輝性塗料は、溶剤の希釈比が大小異なるものを少なくとも二以上調製して、例えば図３の如く、溶剤の希釈比が相対的に大きい光輝性塗料を塗装機７Ａで粗粒化すると同時に、溶剤の希釈比が相対的に小さい光輝性塗料を塗装機７Ｂで粗粒化して、塗装機７Ａで粗粒化した低粘度塗料粒子８と、塗装機７Ｂで粗粒化した高粘度塗料粒子９とをベースコート２が施された基材１の表面に対して互いに入り混じった状態で塗着させる。
【００２０】
これにより、塗膜４は、低粘度塗料粒子８が乾燥固化して成る明輝部Ｘと、高粘度塗料粒子９が乾燥固化して成る暗輝部Ｙとが混在した斑模様１０を現出するものとなっている。
【００２１】
すなわち、基材１の表面に塗着された低粘度塗料粒子８は、溶剤の希釈比が大きいために、溶剤の蒸発に伴う体積収縮作用によって、鱗片状の光輝材３が、塗着面と平行な向きになるように流動せられ、基材１の表面に水平に並んで、キラキラと明るく輝く明輝部Ｘとなる。
【００２２】
一方、高粘度塗料粒子９は、溶剤の希釈比が小さく、体積収縮率が小さいために、光輝材３が流動する度合いも小さく、塗着面と平行な向きになる光輝材３が少ないので、暗くて輝きの少ない暗輝部Ｙとなり、この暗輝部Ｙと明輝部Ｘとが互いに入り混じって、図２の如く明暗のコントラストを成した斬新な斑模様１０を現出する塗膜４が形成される。
【００２３】
また、斑模様１０を構成する明輝部Ｘと暗輝部Ｙは、明暗のコントラストと、観る角度によって各々の輝き度合いや光の反射具合が微妙に変化する視覚効果とが相まって、見掛けの凹凸感を平面の状態で現出し、外観全体に深みや高級感を醸し出す。
【００２４】
なお、明輝部Ｘと暗輝部Ｙとの明暗のコントラストで斑模様１０を現出させるには、塗装機７Ａで粗粒化させる光輝性塗料と、塗装機７Ｂで粗粒化させる光輝性塗料との間における不揮発分の含量差（ΔＮＶ）が、粗粒化時に５〜８重量％、基材１の表面に対する塗着時に１０〜２０重量％になる程度まで、溶剤の希釈比に差を設けることが望ましく、その差が小さいと、明暗のコントラストが弱化して斑模様１０が消失する傾向を示す。
【００２５】
光輝性塗料には、無着色シルバーや、有色のシルバーグレイ、ゴールド、ブルー、レッド、イエロー、バイオレット等々があるが、単色もしくは混色の同色塗料で溶剤の希釈比が大きいものと小さいものを調製しても良いし、例えば、溶剤の希釈比が大きいシルバーと溶剤の希釈比が小さいゴールドとの２色を調製する場合でも良い。
【００２６】
また、光輝性塗料に配合する光輝材３は、アルミ粉、アルミ箔を細断したアルミフレーク、真空蒸着箔を細断した蒸着フレーク等のメタリック顔料に限らず、雲母片に二酸化チタンをコートした雲母チタン等のパール顔料であっても良い。
【００２７】
また、一般のメタリック塗装に使用する塗料の光輝材含量（ＰＷＣ）は、塗料全量の１０重量％前後であるが、少なくとも１重量％以上であれば、メタリック感を出すことができるし、２０重量％以下ならば、塗膜性能も損なわないので、塗装機７Ａ，７Ｂで粗粒化する各光輝性塗料の光輝材３の含量を塗料全量の１〜２０重量％の範囲内で幅広く調製することによって、塗膜４が現出する斑模様１０の色調バリエーションを著しく増やすことができる。
【００２８】
なお、二以上の光輝性塗料を同時に粗粒化する手段としては、図３の如く二以上の塗装機を用いるものに限らず、一つの塗装機に二以上の塗料噴霧ノズルもしくは塗料供給ノズルを併設するものでも良い。
【００２９】
光輝性塗料の粗粒化の程度は、その粗粒化時における塗料粒子８，９の平均粒径が５０〜５００μｍになるようにするのが好ましく、５０μｍ以下の粒径になると、肉眼では斑模様の印象が消失し、また、５００μｍ以上の粒径では、塗膜４の品質低下が問題となる。
【００３０】
次に、光輝性塗料の塗膜４の上に水圧転写によって印刷するインキ模様５は、例えば図４に示す黒色の杉綾図柄ｔや、図６に示す赤，青，黄色の雲形図柄ｓ₁，ｓ₂，ｓ₃と緑色の草の葉図柄p を呈するもので、図４の如き杉綾図柄ｔを呈するインキ模様５をシルバーグレイ単色の光輝性塗料で成る図２の塗膜４の上に印刷すると、そのインキ模様５と塗膜４の斑模様１０とが重なり合って、図５のような合成模様が現出する。
【００３１】
図５の合成模様は、インキ模様５の杉綾図柄ｔと塗膜４のシルバーグレイの地色とが相まって、英国の伝統的な織物地であるツイードに似た端正で落ち着きのある外観を呈すると同時に、これに、塗膜４が現出する斑模様１０の明暗のコントラストや輝きの変化などの視覚効果が加わって、深みや立体感のある上品で高級感あふれた外観を呈する。
【００３２】
また、図６の如き着色図柄ｓ₁，ｓ₂，ｓ₃及びp を呈するインキ模様５を無着色シルバーもしくはシルバーグレイの光輝性塗料で成る図２の塗膜４の上に印刷して、図７のような合成模様を現出させた表面加飾品は、基材の表面に巻いた銀箔を焼き付けて成る銀箔地の上に、着彩用の釉薬を盛りつけて焼成させた銀箔多色盛りの七宝焼と見紛うばかりの華麗な外観を呈する。
【００３３】
すなわち、銀色の斑模様１０を現出する塗膜４の質感や色合いが、七宝焼の銀箔地に似ており、また、その塗膜４の上に着色図柄ｓ₁，ｓ₂，ｓ₃及びp のインキ模様５を印刷した様が、銀箔地の上に着彩用の釉薬を盛りつけて焼成した様に非常に良く似ているので、図７の表面加飾品は、銀箔多色盛りの七宝焼製品に酷似した外観を呈する。したがって、本発明によれば、高価で量産が難しい七宝焼製品の代替品となり得る高級な表面加飾品を安価で量産できるという優れた効果がある。
【００３４】
なお、図１の表面加飾品は、光輝性塗料の塗膜４の表面に、インキ模様５が直接印刷されているが、本発明はこれに限らず、例えば図８に示すように、塗膜４の表面に、無色透明又は着色透明なクリア塗料の塗膜１１を形成してその上からインキ模様５を印刷する場合であっても良い。
【００３５】
この場合は、塗膜４が現出する斑模様１０とその上に印刷されるインキ模様５との間に透明な塗膜１１が介在することにより、両模様１０及び５が重なり合って形成される合成模様の深みや立体感が一層増大されるという効果がある。
【００３６】
【発明の効果】
本発明によれば、鱗片状の光輝材を顔料とする光輝性塗料で、光輝材が明るく輝く明輝部と、光輝材の輝きが暗い暗輝部とが混在した斑模様を現出させると同時に、その斑模様と任意の図柄を呈するインキ模様とが重なり合った深みのある合成模様を現出させて、各種製品の表面に斬新で高級感のある色やテクスチャーを付与することができるという大変優れた効果がある。

BACKGROUND OF THE INVENTION
The present invention is a surface decoration product in which the surface of a base material made of plastic, metal, wood, glass, ceramics, etc. is coated, and the appearance is beautiful with the color and texture of the painted surface (coating surface), and its coating. It relates to the decoration method.
[0002]
[Prior art]
Coating generally has protective effects such as rust prevention, anticorrosion, and weather resistance improvement, improvement of surface hardness and heat resistance, or improvement of physical properties and functions such as imparting electrical insulation and conductivity, and the paint surface has The main purpose is to decorate the appearance with color and texture (texture). Especially for metal products and wood products, it is one of the most important decoration methods to add desired color and texture to the surface. One.
[0003]
On the other hand, for plastic products in which the molding material itself can be colored to the desired color and textured, such as irregularities, can be applied with a molding die, painting is essentially not necessary. Rather than as a surface finish required for metal and wood products (beautification of the appearance), painting was mainly used as an alternative means of printing patterns and marks.
[0004]
Recently, however, the range of use of plastic products has significantly increased, and not only electronic equipment such as home appliances and office automation equipment, but also interior and exterior parts of automobiles have been reduced in weight and improved in formability. Accordingly, the demand for coating plastic products for the purpose of only the decorative effect of beautifying the appearance has increased remarkably.
[0005]
In particular, for interior parts of automobiles, there is a demand for high-quality decorative painting that combines appearance quality that creates a comfortable living space in the vehicle and novelty that satisfies the individualization orientation of users.
[0006]
[Problems to be solved by the invention]
However, in the case of painting, the type and number of paints used are limited, and there are restrictions on how to paint, so that a complex design can be created by combining many colors and motifs as in printing. It is not easy to impart a novel and high-class color and texture to the coating film.
[0007]
In particular, in the case of mechanical coating in which paint is sprayed by a coating machine, it is impossible to impart a three-dimensional effect by undulating the coating film with a brush or a roll, as in the case of spicule coating, and the variation in texture is limited.
[0008]
For building ceilings and walls, spray cereal paint with coarse lime powder or silica powder mixed with cement powder, as well as spicule paint, with a mortar gun of 3 to 5 mm in diameter. However, these coatings are not applicable to the surface finishing of industrial products such as automobiles, home appliances, and electronic devices because the texture of the coating film is too rough.
[0009]
In addition, as a painting means to add texture to the surface of industrial products, hammer tone painting that makes a three-dimensional pattern appear in a flat state by spraying a paint containing silicon resin with a spray gun and hitting it with a hammer, There are cracking paint that sprays cracking enamel on the intermediate coating film and causes cracks in the coating film, and chirimene paint that causes fine shrinkage on the surface of the coating film. It is used for surface finishing of optical machines and metal lockers, and hammer tone coating is also common as surface finishing for machine tools and the like, and lacks novelty and lacks luxury.
[0010]
In addition, metallic paints that show a metallic shine with paints containing glitter materials such as aluminum powder and aluminum flakes, and pearls or rainbows with a paint containing pearl liquid. There is pearl coating, but the monotonous texture that gives the entire coating a uniform metallic luster or pearl luster lacks novelty and may impair the sense of quality depending on the industrial product.
[0011]
Therefore, the present invention uses a glitter paint such as a metallic paint or a pearl paint in which a scaly glitter material is blended as a pigment, and has a novel and high-class feeling by a method different from the conventional metallic paint or pearl paint. The technical challenge is to provide the optimal color and texture for the surface finish of industrial products.
[0012]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention is a surface decoration product in which a part or the whole of the surface is decorated with a coating film of a glittering paint using a scaly glittering material as a pigment, and the dilution of a solvent The low-viscosity paint particles obtained by roughening the glossy paint having a relatively large ratio and the high-viscosity paint particles obtained by coarsening the bright paint having a relatively low solvent dilution ratio are mixed with each other. And a coating film is formed that shows a spotted pattern in which the bright part formed by drying and solidifying the low-viscosity paint particles and the dark part formed by drying and solidifying the high-viscosity paint particles are formed. An ink pattern exhibiting an arbitrary pattern is printed on the coating film.
[0013]
In the process of decorating the surface of the present invention, the low-viscosity paint particles and the high-viscosity paint particles of the glitter paint that are mixed and applied to the surface of the surface decorate in the process of shrinking the volume by evaporation of the solvent and drying and solidifying. Since the low-viscosity paint particles with a large dilution ratio have a large volume shrinkage rate, the volume shrinkage action causes the scaly glittering material contained in the paint particles to flow in a direction parallel to the coating surface. Since it is in a state of being arranged horizontally like scales, the reflectance of light is large and the concealing power of the coating surface is also large, so that the bright and bright bright part is formed.
[0014]
On the other hand, high-viscosity paint particles with a small solvent dilution ratio have a small volume shrinkage rate, so that the scale-like glittering material does not flow at the time of volume shrinkage, and is in a direction parallel to the coating surface. Since there are few, the reflectance of light and the concealment power of a coating surface are small, and it becomes a dark brilliant dark part.
[0015]
As a result, the paint film coated with a mixture of low-viscosity paint particles and high-viscosity paint particles of glitter paint shows a novel spotted pattern with a mixture of bright and dark areas, and at the same time, The brightness of the dark area and the light reflection change slightly depending on the viewing angle, and the change and contrast of light and darkness combine to reveal an apparent unevenness in a flat state. Brew.
[0016]
Furthermore, by printing an ink pattern having an arbitrary pattern on the coating film, a composite pattern in which the ink pattern and a ground pattern composed of a spotted pattern in which bright and dark parts are mixed is overlapped. Appears to have a deeper and more luxurious appearance.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be specifically described below with reference to the drawings.
FIG. 1 is a cross-sectional view showing an example of a surface decorative article according to the present invention, FIG. 2 is a plan view showing the appearance of a coating film of glitter paint formed on the surface of the surface decoration article, and FIG. FIG. 4 is a schematic view showing an example, FIG. 4 is a plan view showing an example of an ink pattern printed on a coating film of a glittering paint, and FIG. 5 is a plan view showing the appearance of a surface decorative article on which the ink pattern is printed, FIG. 6 is a plan view showing a modified example of the ink pattern, FIG. 7 is a plan view showing the appearance of the surface decorative product on which the ink pattern is printed, and FIG. 8 is a cross-sectional view showing a modified example of the surface decorated product.
[0018]
For example, as shown in FIG. 1, the surface decoration product of the present invention is provided with a base coat 2 made of a base-colored paint on the surface of a base material 1 made of a paintable material such as plastic or metal. A coating film 4 of glittering paint using a scaly glittering material 3 as a pigment is formed, and an ink pattern 5 having an arbitrary pattern is printed on the coating film 4 by hydraulic transfer, and further from above A clear coat 6 serving as a surface protective layer is applied with a clear colorless or colored clear paint.
[0019]
At least two glitter paints for forming the coating film 4 having different solvent dilution ratios are prepared. For example, as shown in FIG. 3, a glitter paint having a relatively large solvent dilution ratio is applied to the coating machine 7A. At the same time as the coarsening, the low-viscosity paint particles 8 coarsened by the coating machine 7A and the coarse coating by the coating machine 7B are obtained by roughening the glitter paint having a relatively small solvent dilution ratio and the coating machine 7B. The high-viscosity paint particles 9 thus applied are applied to the surface of the base material 1 on which the base coat 2 has been applied in a mixed state.
[0020]
As a result, the coating film 4 reveals a spotted pattern 10 in which a bright portion X formed by drying and solidifying the low viscosity paint particles 8 and a dark portion Y formed by drying and solidifying the high viscosity paint particles 9 are mixed. It has become a thing.
[0021]
That is, since the low-viscosity paint particles 8 applied to the surface of the substrate 1 have a large solvent dilution ratio, the scaly glittering material 3 is separated from the applied surface by the volume contraction effect accompanying the evaporation of the solvent. It is made to flow so that it may become a parallel direction, and it becomes the bright part X which shines brightly brilliantly along with the surface of the base material 1.
[0022]
On the other hand, since the high-viscosity paint particles 9 have a small solvent dilution ratio and a small volume shrinkage, the degree of flow of the glittering material 3 is small, and the glittering material 3 that is oriented parallel to the coating surface is small. The coating 4 is a dark and low-brilliant dark portion Y, and the dark portion Y and the bright portion X are intermingled with each other, and a novel spotted pattern 10 having a bright and dark contrast as shown in FIG. 2 appears. It is formed.
[0023]
In addition, the bright and dark portions X and Y that make up the mottled pattern 10 are combined with the contrast of light and dark and the visual effect of subtle changes in the degree of brightness and the degree of light reflection depending on the viewing angle. Appears in a flat state, creating a depth and luxury to the entire exterior.
[0024]
In order to make the spotted pattern 10 appear with the contrast of brightness between the bright part X and the dark part Y, the bright paint coarsened by the coating machine 7A and the bright paint coarsened by the coating machine 7B. The difference in the solvent dilution ratio is such that the difference in content of non-volatile components (ΔNV) between 5 and 8 is 5-8% by weight when coarsened and 10-20% by weight when applied to the surface of the substrate 1. If the difference is small, the contrast between light and dark becomes weak and the mottle pattern 10 tends to disappear.
[0025]
Bright paints include uncolored silver, colored silver gray, gold, blue, red, yellow, violet, etc., but they can be prepared in the same or a single color or mixed color paint with a large and small solvent dilution ratio. Alternatively, for example, two colors of silver having a large solvent dilution ratio and gold having a small solvent dilution ratio may be prepared.
[0026]
Further, the glittering material 3 to be blended in the glittering paint is not limited to metallic pigments such as aluminum powder, aluminum flakes obtained by chopping aluminum foil, and vaporized flakes obtained by chopping vacuum deposited foil, and mica pieces are coated with titanium dioxide. Pearl pigments such as titanium mica may be used.
[0027]
Further, the glittering material content (PWC) of the paint used for general metallic coating is about 10% by weight of the total amount of the paint, but if it is at least 1% by weight, a metallic feeling can be obtained, and 20% by weight. % Or less, the coating film performance is not impaired, so the content of the glitter material 3 of each glittering paint coarsened by the coating machines 7A and 7B should be widely prepared within the range of 1 to 20% by weight of the total paint. By this, the color tone variation of the spotted pattern 10 on which the coating film 4 appears can be remarkably increased.
[0028]
The means for simultaneously coarsening two or more glittering paints is not limited to using two or more coating machines as shown in FIG. 3, but two or more paint spray nozzles or paint supply nozzles are provided in one coating machine. It may be a side effect.
[0029]
The degree of coarsening of the glitter paint is such that the average particle diameter of the paint particles 8 and 9 at the time of the coarsening is preferably 50 to 500 μm. The impression of the pattern disappears, and when the particle size is 500 μm or more, the quality of the coating film 4 is degraded.
[0030]
Next, the ink pattern 5 to be printed on the coating film 4 of glitter paint by hydraulic transfer is, for example, the black cypress pattern t shown in FIG. 4 or the red, blue, and yellow cloud pattern s ₁ shown in FIG. An ink pattern 5 having a s ₂ , s ₃ and green grass leaf pattern p and having a herringbone pattern t as shown in FIG. 4 is printed on the coating film 4 of FIG. Then, the ink pattern 5 and the spotted pattern 10 of the coating film 4 overlap each other, and a composite pattern as shown in FIG. 5 appears.
[0031]
The composite pattern in FIG. 5 is a combination of the Sugaya pattern t of the ink pattern 5 and the silver-gray background color of the coating film 4 and exhibits a neat and calm appearance similar to Tweed, a traditional English fabric. At the same time, a visual effect such as contrast of light and darkness and a change in brightness of the spotted pattern 10 on which the coating film 4 appears is added to give an elegant and luxurious appearance with depth and stereoscopic effect.
[0032]
Also, an ink pattern 5 having colored patterns s ₁ , s ₂ , s _3, and p as shown in FIG. 6 is printed on the coating film 4 of FIG. 2 made of an uncolored silver or silver gray glitter paint. The surface decorations that show a synthetic pattern like 7 are silver foil multi-colored assorted with a glaze for coloring on a silver foil ground by baking a silver foil wound around the surface of the base material. It has a brilliant appearance that is often mistaken for Cloisonne ware.
[0033]
That is, the texture and color of the coating film 4 that reveals the silver spotted pattern 10 are similar to the cloisonne baked silver foil, and the colored pattern s ₁ , s ₂ , s ₃ and p are formed on the coating film 4. The ink pattern 5 is very similar to the case where the glaze for coloring is placed on the silver foil and baked, so the surface decoration in Fig. 7 is a cloisonne ware product with multicolored silver foil. Appears very similar to. Therefore, according to the present invention, there is an excellent effect that it is possible to mass-produce high-quality surface decoration products that can be used as substitutes for cloisonne ware products that are expensive and difficult to mass-produce.
[0034]
In addition, although the ink pattern 5 is directly printed on the surface of the coating film 4 of the glitter paint, the surface decoration product of FIG. 1 is not limited to this, and for example, as shown in FIG. The surface of 4 may be formed by forming a clear transparent or colored transparent paint film 11 and printing the ink pattern 5 thereon.
[0035]
In this case, both the patterns 10 and 5 are formed so as to overlap each other because the transparent coating film 11 is interposed between the spotted pattern 10 where the coating film 4 appears and the ink pattern 5 printed thereon. There is an effect that the depth of the composite pattern and the three-dimensional effect are further increased.

【The invention's effect】
According to the present invention, it is a glittering paint using a scaly glitter material as a pigment, and at the same time, a spotted pattern in which a bright portion where the glitter material is bright and a dark portion where the glitter of the glitter material is dark appears. It is very excellent that it can show a deep synthetic pattern where the spotted pattern and the ink pattern with an arbitrary pattern overlap each other, and give the surface of various products a novel and high-class color and texture. There is an effect.
