Description

【０００１】
【発明の属する技術分野】
本発明は、新規な塗膜外観が得られる模様形成塗料およびその製造方法に関し、さらに詳しくは、１回の塗装で被塗装物面に糸状模様を形成することの出来る模様形成塗料およびその製造方法に関する。
【０００２】
【従来の技術】
模様形成塗料の１つとして多彩模用塗料が知られている。この多彩模用塗料は、油性または水性の分散媒中に、この分散媒には溶解しない状態で、いくつかの異なった色調の液状着色塗料を、肉眼で識別できる大きさ、例えば０．５〜数ｍｍの大きさの粒子状態で懸濁分散せしめてなるもので、１回の塗装で色調の異なった斑点状、滴状、粒状等の組み合わせからなる、いわゆる色散らし模様の得られる塗料であり、例えば、ＪＩＳ−Ｋ−５６６７に規定されている。
【０００３】
従来の多彩模様塗料は、前記したように色調の異なった斑点状模様の組み合わせによる変化に富んだ模様塗膜を形成することが出来るので、主として建築物の内外壁面等の塗装仕上げに用いられる場合が多い。しかしこのような多彩模様塗料ではあるが、これから得られる塗膜は、それぞれの色調の異なった着色塗料が、粒子状もしくは斑点状に重なりあって形成される模様であり、全体としては画一化された平面的な多彩模様となるに過ぎず、特に近年、より装飾性ないし意匠性の高い塗装仕上げが要求されている建築仕上げ分野においては、その要求を充分に満たしているとは言い難い。
【０００４】
【発明が解決しようとする課題】
したがって、本発明は、従来の多彩模用塗料が画一化的でかつ平面的で変化に乏しい模様しか得られないという欠点を解決しようとするもので、従来の多彩模様塗料に比較してさらに装飾性ないし意匠性の高い模様を形成することの出来る塗料の提供を目的とする。また、本発明は装飾性ないし意匠性の高い模様を形成することの出来る塗料の製造方法の提供を目的とする。
【０００５】
【課題を解決するための手段】
上記課題は、塗料もしくは分散媒中に、塗膜形成成分および着色剤を少なくとも含有する液状着色塗料を、直径が０．２〜１０ｍｍの細孔を通して糸状物とし、かつ該糸状物が前記塗料もしくは分散媒に溶解することなく、安定な状態で混合せしめて成る模様形成塗料を提供することによって達成できる。この模様形成塗料においては、液状着色塗料の糸状物が少なくともその表層部がゲル化層を形成してなるものが好ましい。
【０００６】
本発明における他の課題は、塗膜形成成分および着色剤を少なくとも含有する液状着色塗料を、該液状着色塗料を溶解することなく安定な分散状態を形成し得る塗料もしくは分散媒中に、直径が０．２〜１０ｍｍの細孔を通して糸状物として混入せしめることから成る模様形成塗料の製造方法を提供することによって達成できる。なお、この方法においては、前記液状着色塗料がゲル形成成分を含有し、前記塗料もしくは分散媒が、前記液状着色塗料中に含有せしめたゲル形成成分をゲル化させることの出来るゲル化剤を含有してなるものであるのが好ましく、また、この方法において塗料もしくは分散媒における分散媒が塗膜形成成分を含有してなるものであるのが好ましい。
【０００７】
以上よりなる本発明の模様形成塗料は、基本的には従来の多彩模用塗料と全く同様の材料を用いて作ることが出来、またその製造方法についても同様である。しかし、本発明の模様形成塗料と従来の多彩模用塗料との最も大きな相違は、従来の多彩模用塗料が、塗料中に分散、混合せしめる液状着色塗料を粒子状としているのに対し、本発明ではこれを糸状物とした点である。したがってこのような相違により、それぞれの塗料から得られる模様においても、従来の多彩模用塗料が、単に斑点状ないし粒子状の組み合わせ模様しか得られないのに対し、本発明の模用形成塗料からは新規にしてかつユニークな糸状模様が得られ、意匠性の点で両者に大きな相違がある。特に本発明の模様形成塗料においては、液状着色塗料を糸状物として混合、分散せしめる塗料もしくは分散媒として、従来の多彩模様塗料を用いると、形成される塗膜は、斑点状もしくは粒子状模様の中に糸状模様が混在し、極めて装飾性の高い模用が得られる。
【０００８】
【発明の実施の形態】
以下、本発明の模用形成塗料により得られた塗膜模様を図面に基づいて説明する。図１は、本発明の模様形成塗料において、液状着色塗料を分散媒中に混合、分散せしめてなる塗料から形成された糸状模様であり、図２は液状着色塗料を塗料中（従来の多彩模用塗料中）に混合、分散せしめてなる塗料から形成された糸状模様である。これら図１および図２において、１は糸状模様、２は被塗装材面、３は多彩模用塗料によって形成された斑点状模様である。
【０００９】
本発明の模様形成塗料を得るに際して用いることの出来る材料としては特に限定するものではなく、塗料業界で公知の種々の材料から適宜に選択して用いることが出来る。先にも述べたように従来の多彩模用塗料の構成材料も本発明においては選択範囲内である。
【００１０】
本発明における液状着色塗料は、塗膜形成成分（例えば、ニトロセルロース、アクリル樹脂、塩化ビニル樹脂、酢酸ビニル樹脂、ポリスチレン、アクリロニトリル等の合成樹脂または天然ゴムもしくは合成ゴム等の塗料用バインダー）を、水ないし水性溶媒、もしくは適宜な有機溶媒（例えば、トルエン、キシレン、酢酸エチル、酢酸ブチル、アセトン、メチルエチルケトン、メチルアルコール、ブチルアルコール、プロピルアルコール、ブチルセロソルブ等）に溶解ないしは分散、または、エマルションとした樹脂液に、無機もしくは有機顔料（例えば、二酸化チタン、黄色酸化鉄、ベンガラ、クロムグリーン、紺青、カーボンブラック、ハンザイエロー、レーキレッド、キナクリドンバイオレッド、銅フタロシアニン、炭酸カルシウム、硫酸バリウム、タルク、クレー等）および必要ならば塗料用として公知の種々の添加剤（例えば、分散剤、消泡剤、レベリング剤、増粘剤、造膜助剤、防カビ剤等）を慣用量で混合、分散せしめることによって得られる。
【００１１】
上記液状着色塗料を分散せしめるための塗料もしくは分散媒（以下、分散媒体という）としては、有機溶媒系または水系の何れの分散媒体でも良く、上記液状着色塗料の構成成分と同様な塗膜形成成分、着色剤を含む着色塗料を分散媒体としても良い。また、従来の多彩模用塗料を分散媒体としても良い。なお、上記液状着色塗料自体に塗膜形成性能が備わっているため、分散媒体への塗膜形成成分の添加は、本発明においては必須の要件ではないが、分散媒体への塗膜形成成分の添加は塗膜強度を強くすることが出来、かつ、被塗物への密着強度も強くなるため有効な手段である。
【００１２】
本発明において、分散媒体として着色塗料を用いた場合には、該着色塗料の背景色の中に糸状模様が形成される。したがって着色塗料の色調と糸状模様の色調を変えることによって装飾効果は高まる。また分散媒体として多彩模様塗料を用いた場合には、多彩模様の背景色に糸状模様が組み合わされてさらに装飾性の高いものとなるので、このような着色塗料ないしは多彩模様塗料を分散媒体として用いることは本発明にとっては好ましい。
【００１３】
上記液状着色塗料の糸状物を分散媒体中に安定状態で混合分散させておくためには相互に溶解しないようにする必要がある。一例としては、液状着色塗料を水不溶性有機溶媒系の組成とし、これを水性系分散媒体中に分散させる方法、または、液状着色塗料をゲルもしくはゾル塗料として分散媒体中に分散させる方法、または、液状着色塗料の糸状物をカプセル化して分散させる方法等により行うことが出来る。特に本発明においては、液状着色塗料の糸状物の分散安定性が優れていること、および、製造が比較的容易であることなどから、該糸状物の少なくとも表層部にゲル化層の形成された糸状物とするのが好ましい。
【００１４】
液状着色塗料の糸状物の表層にゲル化層を形成するには、特公昭５１−６１７５号公報に記載されている方法によって行うことが出来る。すなわち、この方法はポリビニルアルコールのような親水性コロイド形成物質と、該コロイド物質を不溶化することの出来るホウ酸塩のような不溶化剤（ゲル化剤）とが作用しあって、一種の三次元的網状構造の形成されるゲル化反応を利用するもので、このゲル化反応を、糸状物の表層部で生じさせることにより、分散媒体中での分散安定性に優れた糸状物とすることが出来る。
【００１５】
より具体的には、液状着色塗料の構成成分の一つである塗膜形成成分を合成樹脂エマルションとし、かつ、着色剤および親水性コロイド形成物質を含有せしめて液状着色塗料とする。一方、分散媒体を水系とすると共に、該分散媒体には前記親水性コロイド形成物質をゲル化させることの出来るゲル化剤を含有せしめ、この分散媒体中に前記液状着色塗料を混入せしめると、混入と同時に糸状物の表層でゲル化反応が生じ、ゲル化層が形成される。
【００１６】
ゲル化層の形成において用いることの出来るコロイド形成物質およびゲル化剤並びにその組み合わせを例示すると下記表１のごときものである。
【００１７】
【表１】

【００１８】
本発明に係わる模様形成塗料の製造方法としては、以上のような構成からなる液状着色塗料および分散媒体を用い、該液状着色塗料を分散媒体中に糸状物として混入せしめることからなる。液状着色塗料を糸状物とするには、液状着色塗料を、細孔を有した治具の中を自由落下方式、あるいはポンプによる圧送方式等によって通過させる方法によるものが好ましい。糸状物となった液状着色塗料は、これを分散媒体中に混入せしめ、次いで適度なせん弾力の付加されるような分散機で分散することにより、糸状物は模様形成に適度な長さに切断され、分散媒体中に混合分散される。糸状物の大きさは本発明において何ら限定されるものではなく、所望する模様となるように、液状着色塗料もしくは分散媒体の粘度、糸状物とする際に用いる治具の細孔径、該細孔を通す際の圧力、分散媒中に混入せしめた後の分散条件を変えることによって適宜とすることが出来る。
【００１９】
具体例としては、液状着色塗料を糸状物とする際に用いる治具の細孔の大きさは直径０．２〜１０ｍｍとするのが好ましく、特に０．５〜３ｍｍの範囲であるのが好ましい。その細孔の大きさが０．２ｍｍより小さいと糸状物が細くなり過ぎ明瞭な糸状模様の現出が難しく、また、液状着色塗料を押し出す時間が長くなり生産性が悪くなる。また、１０ｍｍを超えると形成される糸状模様が太くなり過ぎ、高意匠性を得るのが難しくなる。
【００２０】
液状着色塗料の粘度は１０〜４００ｄＰａ．ｓの範囲とするのが好ましく、特に５０〜３００ｄＰａ．ｓの範囲であるのが好ましい。その粘度が１０ｄＰａ．ｓより低いと、細孔を通した際に出てくる液状着色塗料の糸状物が細すぎるため、本発明の目的とする糸状模様がはっきりと分かる塗膜が得難くなり、また、柔らかくなり、切れやすくなるため、糸状物としての形状を保持するのが難しくなる。その粘度が４００ｄＰａ．ｓより高くなると液状着色塗料を細孔より押し出す時間が長くなり生産性が悪くなる他、塗布した際の糸状物のフロー性が悪くなり、平滑性に優れた模様塗膜の形成が難しくなる。
【００２１】
液状着色塗料を細孔を通して糸状物とし、これを分散媒体中に安定に分散するためには、塗料業界で一般的に用いられる円盤型の分散羽根を備えたディゾルバー型の分散機などを用いることにより達成できる。
【００２２】
本発明の模様形成塗料において、液状着色塗料は、該模様形成塗料中に５〜８０重量％含まれることが好ましい。液状着色塗料が５重量％より少ないと、形成される模用塗料中の糸状物の量が少なすぎて、塗装により得られる模様塗膜中の糸状模様がわずかに存在したものとなり装飾性の乏しいものとなる。また、液状着色塗料が８０重量％以上となるると、形成される模様塗膜中の糸状模様の量が多くなりすぎ、糸状模様の重なり合いが生じ、糸状模様としては判別しにくく、装飾性の乏しいものとなる。
【００２３】
以上のようにして得られた模様形成塗料は、塗料業界で公知の各種塗装方法、例えば刷毛、スプレー、ローラー、カーテンフローコーター等の塗装法により種々の基材面に塗布し、糸状模様が形成される。特に本発明の模様形成塗料によって最も効果的な糸状模様が得られる塗装方法としてはスプレー塗装が好ましい。
【００２４】
本発明の模様形成塗料は、コンクリート板、石綿セメント板、ハードボード、石膏ボード、石綿パーライト板、ケイ酸カルシュウム板等の建築用ボード類、ＡＢＳ樹脂、スチレン樹脂、アクリル樹脂、塩化ビニル樹脂、メラミン樹脂、ポリエステル樹脂等のプラスチック類、鉄板、アルミ板、ブリキ板、トタン板等の金属類、木材、合成木材ガラス、セラミック等広範囲な材料に塗装することが出来る。
【００２５】
本発明の模様形成塗料は、上記種々の基材面に直接塗装しても良いが、これら基材面に予め装飾塗装を施した後に塗装しても良い。このようにすると装飾塗装面が背景色となり、これに本発明による糸状模様が重なりあって極めて装飾性の高い模様が形成される。この場合の装飾塗装は通常の着色塗料でも良く、また、従来の多彩模用塗料であっても良い。更に、また、背景色と糸状模様の色調を変える方法、糸状物の色調を２つまたはそれ以上の複数色とし、これを混合する方法、あるいはこれらを適宜に組み合わせることによって、さらに複雑でかつ変化に富んだ高い装飾性ないし意匠性を有する模用の形成が可能となる。

BACKGROUND OF THE INVENTION
The present invention relates to a pattern-forming paint capable of providing a novel coating film appearance and a method for producing the same, and more particularly, a pattern-forming paint capable of forming a thread-like pattern on the surface of an object to be coated by a single coating and a method for producing the same. About.
[0002]
[Prior art]
A variety of paints are known as one of pattern forming paints. This versatile paint is a size that can distinguish several colored liquid paints with the naked eye in an oily or aqueous dispersion medium in a state in which it is not dissolved in the dispersion medium, for example, 0.5 to It is a paint that can be dispersed and dispersed in the state of particles of several mm in size, and it is a paint that can be used to obtain a so-called dispersal pattern consisting of a combination of spots, drops, granules, etc., with different colors in a single coating. For example, it is defined in JIS-K-5667.
[0003]
Conventional multicolor pattern paint can form a pattern paint film with various changes by combining spotted patterns with different colors as described above. There are many. However, although it is such a colorful pattern paint, the coating film obtained from this is a pattern formed by overlapping colored paints of different colors in the form of particles or spots, and the whole is unified. In particular, in the field of architectural finishing, which has recently been demanding a paint finish with higher decorativeness or design, it is difficult to say that the requirement is sufficiently satisfied.
[0004]
[Problems to be solved by the invention]
Therefore, the present invention is intended to solve the disadvantage that the conventional multicolored paint can obtain only a uniform, flat and poorly changing pattern. It aims at providing the coating material which can form a pattern with high decorativeness or design. Moreover, this invention aims at provision of the manufacturing method of the coating material which can form a pattern with high decorating property or design property.
[0005]
[Means for Solving the Problems]
The above-mentioned problem is that a liquid colored paint containing at least a coating film forming component and a colorant in a paint or a dispersion medium is made into a thread through a pore having a diameter of 0.2 to 10 mm , and the thread is said paint or This can be achieved by providing a pattern-forming paint that is mixed in a stable state without dissolving in the dispersion medium. In this pattern forming coating material, it is preferable that the thread-like material of the liquid coloring coating material has at least a surface layer portion forming a gelled layer.
[0006]
Other object of the present invention, the liquid colored coating containing at least a film forming component and a colorant, in the coating or dispersion medium to form a stable dispersion state without dissolving the liquid colored coating, diameter This can be achieved by providing a method for producing a pattern-forming paint comprising mixing through a 0.2 to 10 mm pore as a thread. In this method, the liquid color paint contains a gel-forming component, and the paint or dispersion medium contains a gelling agent that can gel the gel-formation component contained in the liquid color paint. In this method, it is preferable that the dispersion medium in the paint or dispersion medium contains a coating film forming component.
[0007]
The pattern-forming paint of the present invention as described above can be basically produced using the same material as the conventional multicolor paint, and the production method thereof is also the same. However, the biggest difference between the pattern-forming paint of the present invention and the conventional multicolor paint is that the conventional multicolor paint is in the form of particles in the liquid color paint that is dispersed and mixed in the paint. In the present invention, this is a thread. Therefore, due to such differences, the conventional various pattern paints can be obtained only in the form of spots or particles in combination with the patterns obtained from the respective paints. Has a new and unique thread-like pattern, and there is a great difference between them in terms of design. In particular, in the pattern forming paint of the present invention, when a conventional multicolored paint is used as a paint or dispersion medium in which a liquid colored paint is mixed and dispersed as a filamentous material, the coating film formed has a spotted or particulate pattern. A string-like pattern is mixed inside, and an imitation with extremely high decorativeness can be obtained.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the coating film pattern obtained with the imitation forming paint of the present invention will be described with reference to the drawings. FIG. 1 shows a thread-like pattern formed from a paint obtained by mixing and dispersing a liquid colored paint in a dispersion medium in the pattern forming paint of the present invention, and FIG. 2 shows a liquid colored paint in the paint (a variety of conventional patterns). It is a thread-like pattern formed from a paint mixed and dispersed in the paint for use. 1 and 2, reference numeral 1 denotes a thread-like pattern, 2 denotes a surface of a material to be coated, and 3 denotes a spot-like pattern formed by a variety of paints.
[0009]
The material that can be used for obtaining the pattern-forming paint of the present invention is not particularly limited, and can be appropriately selected from various materials known in the paint industry. As described above, the constituent materials of the conventional multicolor paint are also within the selection range in the present invention.
[0010]
The liquid colored paint in the present invention is a coating film forming component (for example, a synthetic resin such as nitrocellulose, acrylic resin, vinyl chloride resin, vinyl acetate resin, polystyrene, acrylonitrile, or a binder for paint such as natural rubber or synthetic rubber), Resin dissolved or dispersed in water or an aqueous solvent or an appropriate organic solvent (for example, toluene, xylene, ethyl acetate, butyl acetate, acetone, methyl ethyl ketone, methyl alcohol, butyl alcohol, propyl alcohol, butyl cellosolve, etc.) or an emulsion In the liquid, inorganic or organic pigments (for example, titanium dioxide, yellow iron oxide, bengara, chrome green, bitumen, carbon black, Hansa yellow, lake red, quinacridone bio red, copper phthalocyanine, calcium carbonate, Barium, talc, clay, etc.) and various known additives for paints (for example, dispersants, antifoaming agents, leveling agents, thickeners, film-forming aids, antifungal agents, etc.) are commonly used. It is obtained by mixing and dispersing in quantities.
[0011]
The paint or dispersion medium (hereinafter referred to as the dispersion medium) for dispersing the liquid colored paint may be either an organic solvent-based or water-based dispersion medium, and a coating film forming component similar to the constituent of the liquid colored paint. Further, a colored paint containing a colorant may be used as the dispersion medium. In addition, a variety of conventional paints may be used as the dispersion medium. In addition, since the above-mentioned liquid colored coating material itself has a coating film forming performance, the addition of the coating film forming component to the dispersion medium is not an essential requirement in the present invention, but the coating film forming component to the dispersion medium is not necessary. The addition is an effective means because it can increase the strength of the coating film and also increases the strength of adhesion to the object.
[0012]
In the present invention, when a colored paint is used as the dispersion medium, a thread-like pattern is formed in the background color of the colored paint. Therefore, the decoration effect is enhanced by changing the color tone of the colored paint and the color tone of the thread-like pattern. In addition, when a multicolored pattern paint is used as a dispersion medium, a threadlike pattern is combined with the background color of the multicolored pattern to further enhance the decoration. Therefore, such a colored paint or a multicolored pattern paint is used as the dispersion medium. This is preferred for the present invention.
[0013]
In order to stably mix and disperse the above-mentioned liquid colored paint filaments in the dispersion medium, it is necessary not to dissolve them. As an example, the liquid coloring paint has a water-insoluble organic solvent-based composition and is dispersed in an aqueous dispersion medium, or the liquid coloring paint is dispersed in a dispersion medium as a gel or sol paint, or It can be performed by a method of encapsulating and dispersing a thread-like material of a liquid coloring paint. In particular, in the present invention, a gelled layer is formed on at least the surface layer of the filamentous material because the dispersion stability of the filamentous material of the liquid coloring paint is excellent and the production is relatively easy. A filamentous material is preferred.
[0014]
Forming the gelled layer on the surface layer of the liquid colored paint thread can be carried out by the method described in Japanese Patent Publication No. 51-6175. That is, in this method, a hydrophilic colloid-forming substance such as polyvinyl alcohol and an insolubilizing agent (gelling agent) such as a borate capable of insolubilizing the colloidal substance act to form a kind of three-dimensional The gelation reaction that forms a mechanical network structure is used, and by generating this gelation reaction at the surface layer portion of the filamentous material, a filamentous material having excellent dispersion stability in the dispersion medium can be obtained. I can do it.
[0015]
More specifically, the coating film forming component, which is one of the components of the liquid colored paint, is a synthetic resin emulsion, and a colorant and a hydrophilic colloid-forming substance are contained to form a liquid colored paint. On the other hand, when the dispersion medium is water-based, the dispersion medium contains a gelling agent capable of gelling the hydrophilic colloid-forming substance, and the liquid coloring paint is mixed into the dispersion medium. At the same time, a gelation reaction occurs in the surface layer of the filamentous material, and a gelled layer is formed.
[0016]
Examples of colloid-forming substances, gelling agents and combinations thereof that can be used in the formation of the gelled layer are shown in Table 1 below.
[0017]
[Table 1]

[0018]
As a method for producing a pattern-forming paint according to the present invention, a liquid colored paint and a dispersion medium having the above-described structure are used, and the liquid colored paint is mixed as a thread into the dispersion medium. In order to make the liquid coloring paint into a filamentous material, it is preferable to use a method in which the liquid coloring paint is passed through a jig having pores by a free drop method or a pumping method using a pump. The liquid colored paint in the form of a thread-like material is mixed in a dispersion medium, and then dispersed with a dispersing machine to which an appropriate elasticity is applied, whereby the thread-like material is cut to an appropriate length for pattern formation. And mixed and dispersed in a dispersion medium. The size of the filamentous material is not limited at all in the present invention. The viscosity of the liquid colored paint or dispersion medium, the pore diameter of the jig used for forming the filamentous material, and the pore so as to obtain a desired pattern The pressure can be appropriately determined by changing the pressure at the time of passing through and the dispersion conditions after mixing in the dispersion medium.
[0019]
As a specific example, the size of the pores of the jig used when the liquid coloring paint is used as a filamentous material is preferably 0.2 to 10 mm in diameter, and particularly preferably in the range of 0.5 to 3 mm. . If the size of the pores is smaller than 0.2 mm, the thread-like material becomes too thin and it is difficult to reveal a clear thread-like pattern, and the time for extruding the liquid colored paint becomes longer, resulting in poor productivity. On the other hand, if it exceeds 10 mm, the thread pattern formed becomes too thick, and it becomes difficult to obtain high designability.
[0020]
The viscosity of the liquid coloring paint is 10 to 400 dPa.s. s in the range of 50 to 300 dPa.s. The range of s is preferable. Its viscosity is 10 dPa.s. If it is lower than s, since the thread-like material of the liquid colored paint that comes out when passing through the pores is too thin, it becomes difficult to obtain a coating film that clearly shows the target thread-like pattern of the present invention, and it becomes soft. Since it becomes easy to cut | disconnect, it becomes difficult to hold | maintain the shape as a filament. Its viscosity is 400 dPa.s. If it is higher than s, the time for extruding the liquid colored paint from the pores becomes longer and the productivity becomes worse, and the flowability of the filamentous material when applied becomes worse, and it becomes difficult to form a pattern coating film with excellent smoothness.
[0021]
Use a dissolver type disperser equipped with disk-shaped dispersion blades commonly used in the paint industry in order to make the liquid colored paint into a thread through the pores and stably disperse it in the dispersion medium. Can be achieved.
[0022]
In the pattern forming paint of the present invention, the liquid colored paint is preferably contained in the pattern forming paint in an amount of 5 to 80% by weight. When the amount of the liquid coloring paint is less than 5% by weight, the amount of the thread-like material in the pattern paint to be formed is too small, and there is a slight amount of the thread-like pattern in the pattern coating film obtained by painting, resulting in poor decoration. It will be a thing. Further, when the liquid coloring paint is 80% by weight or more, the amount of the thread-like pattern in the pattern coating film to be formed becomes too large, resulting in an overlap of the thread-like patterns, which is difficult to distinguish as a thread-like pattern, and has a decorative property. It will be scarce.
[0023]
The pattern-forming paint obtained as described above is applied to various substrate surfaces by various painting methods known in the paint industry, such as brushes, sprays, rollers, curtain flow coaters, etc. Is done. In particular, spray coating is preferred as the coating method for obtaining the most effective thread-like pattern with the pattern forming paint of the present invention.
[0024]
The pattern-forming paint of the present invention includes concrete boards, asbestos cement boards, hard boards, gypsum boards, asbestos perlite boards, calcium silicate boards and other building boards, ABS resins, styrene resins, acrylic resins, vinyl chloride resins, melamines. It can be applied to a wide range of materials such as plastics such as resin and polyester resin, metals such as iron plate, aluminum plate, tin plate and tin plate, wood, synthetic wood glass and ceramic.
[0025]
The pattern-forming paint of the present invention may be applied directly to the above-mentioned various substrate surfaces, but may also be applied after applying decorative coating to these substrate surfaces in advance. In this way, the decorative painted surface becomes the background color, and the thread-like pattern according to the present invention is overlapped with this to form a very decorative pattern. In this case, the decorative coating may be a normal colored paint or a conventional multicolor paint. Furthermore, the method of changing the color tone of the background color and the thread-like pattern, the method of changing the color tone of the thread-like material into two or more colors, and mixing them, or combining them as appropriate, are further complicated and varied. It is possible to form a pattern having a high decorativeness or design.
