〈発明が解決しようとする課題〉
しかし、上記したような方法ではそれぞれに欠点がある
。) <Problem to be solved by the invention> However, each of the above methods has drawbacks.
例えば上記した（ａ）の方法によるエツチングでは鋼板
を腐食液により腐食して凹部を形成する方法であるため
、鋼板の厚さ以上の深さを形成することは不可能である
。この為、深い凹部を形成する場合には厚い鋼板を使用
する必要があり、重量増加及び価格上昇の問題を生ずる
ことになる。また、その工程において、マスク材の貼着
力によってはエツチング途中で剥離したり、エツチング
後の除去に手間取ったりする欠点をも有している。For example, in the etching method (a) described above, since the recesses are formed by corroding the steel plate with a corrosive liquid, it is impossible to form a recess that is deeper than the thickness of the steel plate. For this reason, when forming deep recesses, it is necessary to use thick steel plates, resulting in problems of increased weight and price. Furthermore, in this process, depending on the adhesion strength of the mask material, it may peel off during etching, or it may take time to remove it after etching.
次に、上記した（ｂ’）のエンボス加工法では、金型を

いる。Next, in the above-mentioned embossing method (b'), a mold is made and mechanically pressed and deformed to form unevenness, so the manufacturing of the mold is expensive and there are many types of embossing. Unable to handle uneven shapes. Further, there is also the problem that the steel plate is distorted or warped due to deformation, which impairs its appearance.

定される問題をも有している。Further, in the pattern painting method (C), a hammer tone paint, a shrinking paint, etc. are used, but the patterns that can be expressed are severely limited, and the recesses formed are also about 1 m long. Additionally, since they generally have low robustness, they have the problem of being limited to use as decoration.

多く、且つ手間や時間が掛るという問題を有している。Furthermore, the water resistance of adhesives and adhesives is an issue in the method of pasting sheets (dl), the method of gluing tiles (e), and the method of gluing or pasting other molded parts. Moreover, there are many restrictions on the work of gluing and pasting, and there are problems in that it takes time and effort.
従って、上記したような欠点のない凹凸表面を有する被
覆鋼材が嘱望されていた。Therefore, a coated steel material having an uneven surface free from the above-mentioned defects has been desired.
（課題を解決するための手段）
本発明は上記に鑑み提案されたもので、鋼板の表面に光

有する被覆鋼板及びその製造方法に関するものである。(Means for Solving the Problems) The present invention has been proposed in view of the above, and the photocurable resin composition is formed by applying a photocurable resin composition to the surface of a steel plate and partially irradiating it with light. A coated steel sheet having an uneven surface and a method for producing the same, characterized in that a hardened portion and an unhardened portion are formed, and a coating layer is formed on the surface of the steel sheet after the unhardened portion is removed. It is.
まずζ本発明に使用する鋼板には、強度や耐腐食性の高
いステンレス鋼板等が使用されるが、通常塗装に供する
場合と同様に前処理を行うことが望ましい、この前処理
とは、例えば脱脂後サンドブラストまたは塗布形クロメ
ート液で処理した後、エポキシ樹脂系塗料をブライマー
（下塗り剤）として塗布するものである。First, the steel plate used in the present invention is a stainless steel plate with high strength and corrosion resistance, but it is desirable to perform pretreatment in the same way as when applying it to normal painting.This pretreatment includes, for example, After degreasing, sandblasting or coating with a chromate solution, an epoxy resin paint is applied as a primer (undercoat).
また、本発明に使用する光硬化性樹脂組成物としては、
光重合性ビニル化合物を必須成分とし、その他には顔料
、充填剤、揺変性剤、光増感剤（光開始剤）、希釈剤等
を添加してもよい。ここで、光重合性ビニル化合物とは
、分子内に光重合性ビニル基を１以上有するものであ−
リ、通常光重合性ビニル基が１つのものと２つ以上のも
のとを併用して重合後には三次元架橋するように構成す
る。In addition, the photocurable resin composition used in the present invention includes:
The photopolymerizable vinyl compound is an essential component, and pigments, fillers, thixotropic agents, photosensitizers (photoinitiators), diluents, etc. may also be added. Here, the photopolymerizable vinyl compound is one having one or more photopolymerizable vinyl groups in its molecule.
(2) Usually, one photopolymerizable vinyl group and two or more photopolymerizable vinyl groups are used in combination so that three-dimensional crosslinking occurs after polymerization.
なお、上記した光硬化性樹脂組成物に照射する光は、紫
外線若しくは電子線等の放射線でよく、選定した光に応
じて光源及び上記した光硬化性樹脂組成物を調整すれば
よい。Note that the light irradiated onto the photocurable resin composition described above may be radiation such as ultraviolet rays or electron beams, and the light source and the photocurable resin composition described above may be adjusted according to the selected light.
紫外線照射を使用する場合は、照射エネルギーが低いの
で、光硬化性樹脂組成物として光重合性ビニル化合物と
光増感剤とを併用する必要がある。また、塗布膜が厚い
程、顔料や充填剤の混合量が制限されることとなる。こ
れは、顔料や充填剤が光重合性ビニル化合物を隠蔽した
り、光を吸収若しくは反射するためであり、隠蔽性の高
い顔料や金属顔料等を大量に使用する場合は乾燥不良を
生じやすい。When using ultraviolet irradiation, since the irradiation energy is low, it is necessary to use a photopolymerizable vinyl compound and a photosensitizer together as a photocurable resin composition. Furthermore, the thicker the coating film, the more limited the amount of pigments and fillers to be mixed. This is because the pigment or filler hides the photopolymerizable vinyl compound or absorbs or reflects light, and if a large amount of pigments or metal pigments with high hiding properties are used, poor drying tends to occur.
一方、電子線等の放射線を使用して照射する場合は、照
射エネルギーが高く、通常は光増感剤の添加を必要とし
ない。また、上記したような顔料や充填剤の使用につい
ても特に制限されることもな（、乾燥不良を起しに（い
が、照射エネルギーが強すぎて他部材が老化する等の悪
影響を及ぼす虞れがあり、さらには照射装置が大型であ
るという課題を有している。On the other hand, when irradiating with radiation such as an electron beam, the irradiation energy is high and the addition of a photosensitizer is usually not required. In addition, there are no particular restrictions on the use of pigments or fillers as described above (because they may cause poor drying), but there is a risk that the irradiation energy may be too strong and cause adverse effects such as aging of other components. Furthermore, there are problems in that the irradiation device is large.
従って、通常は最も技術的に成熟している紫外線を、水
銀ランプ或いはメタルハライドランプ等を光源として照
射すればよい。Therefore, it is usually sufficient to irradiate ultraviolet rays, which are the most technologically mature, using a mercury lamp, a metal halide lamp, or the like as a light source.
上記した光硬化性樹脂組成物は前記した鋼板の表面にス
プレー装置や刷毛、ローラー等を用いて塗布する。The photocurable resin composition described above is applied to the surface of the steel plate using a spray device, a brush, a roller, or the like.
なお、光硬化性樹脂組成物が高粘度の液体或いはチクソ
トロビック性の高い液体であれば、塗布後の流動性が殆
どなく、凸部の厚い成形に好適なものとなる。Note that if the photocurable resin composition is a liquid with high viscosity or a liquid with high thixotropic properties, it will have almost no fluidity after application and will be suitable for molding thick convex portions.

化部分と未硬化部分とを形成するのであるが、部分的に
光を照射する方法として、例えば陰影を何する光フィル
ターを使用する。In the present invention, after applying a photocurable resin to the surface of a steel plate as described above, light is partially irradiated to form a hardened portion and an uncured portion of the photocurable resin. For example, a light filter is used to create shadows.
このフィルターは、透明な板状材に陰影部分を設けて作

脂組成物の未硬化部分を形成させるために設けられるも
のである。This filter is manufactured by providing a shaded portion on a transparent plate-like material, and this shaded portion is provided to block light and form an uncured portion of the photocurable resin composition.
上記した光フィルターの陰影部分は、写真や印刷、その
他の方法により容易に作製することができ、多種類の陰
影を有する光フィルターを使用することによって多種類
の凹凸形状を作製することができるものである。The shaded areas of the above-mentioned optical filter can be easily created by photography, printing, or other methods, and by using an optical filter with many types of shading, many types of uneven shapes can be created. It is.
従って、上記したように作製した陰影を有する光フィル
ターを通して光硬化性樹脂組成物に光を照射すると、透
明部分で光が照射された硬化部分と、濃色で光が照射さ
れない未硬化部分とを同時に形成することができる。Therefore, when light is irradiated on the photocurable resin composition through the light filter having a shade produced as described above, the cured portion that is transparent and is irradiated with light, and the uncured portion that is dark and is not irradiated with light. can be formed simultaneously.
また、光硬化性樹脂組成物の硬化部分は三次元架橋して
不溶性となっていて、未硬化部分は、前記したように光

Next, a polypropylene film with a thickness of approximately 50 μm with a tile-like pattern drawn with black paint is closely attached to the coated surface and passed through an ultraviolet irradiation device. When the film is peeled off, the area with the pattern painted with black paint is visible. Since it was uncured, it was removed by cleaning with a solvent to obtain a stainless steel plate with an uneven surface. The convex portions of the uneven surface are a yellowish semi-transparent layer, and the concave portions are a white stainless steel plate. The entire surface was coated with Power Flon #3000S I super weather-resistant fluororesin paint (manufactured by Mizutani Paint Co., Ltd.
