うものである。[Problems to be Solved by Conventional Techniques and Inventions] Recently, there is a can using a thin tin-plated steel plate for a can, which is not coated with a white coat and is printed with a clear ink for the purpose of designing or reducing the can manufacturing cost. It has increased. In such a can, the surface texture of the thin tin-plated steel sheet greatly affects the surface appearance after printing, and if the surface texture is not appropriate, the appearance deteriorates. In other words, the brightness of the surface after printing is inferior, the image is deteriorated, and the product sales are adversely affected.

Free Sn0.2~1.2g / m 2 on the steel sheet surface, the metal chromium 5 to 25 mg / m 2 as an upper layer, further the metal chromium layer to hydrated chromium oxide 3 to 20 mg / m 2 (as amount of chromium) product Excuse me,
It is a thin tin-plated steel sheet with excellent appearance after printing.

ー処理しないものにも適用は可能である。Among thin tin-plated steel sheets, those mainly based on seam-welded cans require a certain amount or more of unalloyed metal tin (hereinafter referred to as free Sn) from the viewpoint of ensuring weldability. Such a thin tin-plated steel sheet can exhibit sufficient practical performance with or without reflow treatment, but the one subjected to reflow treatment eliminates fine pores in the deposited tin crystal and contributes to corrosion resistance. Iron-tin alloys can be produced, and the overall corrosion resistance tends to be slightly superior. Therefore, although the present invention is intended for the thin tin-plated steel sheet that has been subjected to the reflow treatment, it can be applied to those that are not subjected to the reflow treatment.
鋼板表面に生成せしめるフリーSn0.2〜1.2g/m2で印刷後
の明度を向上することができる。即ち第１図に示すごと

板表面粗度範囲で、そのスクラッチ目を残し表面の鏡面
化を防ぐことができることからＬ値（ハンタ表色系にお
けるＬ値で、本発明においては拡散反射光によるＬ値を
意味する）を高めることができ明度を向上することがで
きる。Free Sn 0.2-1.2 g / m 2 generated on the surface of the steel sheet can improve the brightness after printing. That is, as shown in FIG. 1, in the free Sn in this range, as will be described later, it is possible to leave scratch marks in the steel plate surface roughness range and prevent the surface from being mirror-finished, so that the L value (in the Hunter color system) In the present invention, the L value means the L value due to the diffuse reflection light, and the brightness can be improved.
本発明者らの検討では、目視による明るさは拡散反射光
（鏡面反射を除いたもの）によるＬ値と良い対応があっ
たので、これを明るさの指標とした。具体的には黄色ク
リアー系インキを30mg/dm2印刷焼付し、その後JIS Z872
2に規定されている45゜−０゜方式で受光測色し、Ｌ値
を求めるものである。In the study by the present inventors, the brightness by visual observation had a good correspondence with the L value by diffused reflection light (excluding specular reflection), so this was used as an index of brightness. Specifically, 30 mg / dm 2 of yellow clear ink was printed and then JIS Z872
The L value is obtained by measuring the received light and measuring the color by the 45 ° -0 ° method specified in 2.
フリーSnが1.2g/m2を超えると表面がほとんど鏡面化
し、拡散反射光によるＬ値が低下し、外観が暗くなり好
ましくない。If the free Sn exceeds 1.2 g / m 2 , the surface becomes almost mirror-like and the L value due to diffuse reflected light is lowered, and the appearance becomes dark, which is not preferable.
一方フリーSnが0.2g/m2未満であると溶接缶用素材とし
て最も重要な特性であるシーム溶接性が劣るため好まし
くない。On the other hand, if the free Sn is less than 0.2 g / m 2 , the seam weldability, which is the most important property as a material for welding cans, is deteriorated, which is not preferable.
次に第２図に示すごとく、表面粗度0.1〜0.5Raμｍの範
囲で上記フリーSnによる鏡面化が防止でき、粗度が0.5R
aμｍ超になると、特にリフロー処理後にSnめっき層に
よる素地鋼板被覆が不十分になり耐食性が劣化し好まし
くない。また粗度が0.1Raμｍ未満では表面が容易に鏡
面化し好ましくない。Next, as shown in Fig. 2, in the surface roughness range of 0.1 to 0.5 Raμm, the mirror surface can be prevented by the free Sn and the roughness is 0.5R.
If it exceeds a μm, the coating of the base steel sheet with the Sn plating layer becomes insufficient especially after the reflow treatment, and the corrosion resistance deteriorates, which is not preferable. Further, when the roughness is less than 0.1 Raμm, the surface easily becomes a mirror surface, which is not preferable.
又第３図に示すごとく、フリーSnの上層に生成せしめる
金属クロムは５〜25mg/m2の範囲で、明度を損なわずに
耐食性等クロムめっきとしての機能を発揮することがで
きる。Further, as shown in FIG. 3, the amount of metallic chromium formed on the upper layer of free Sn is in the range of 5 to 25 mg / m 2 , and the function as chromium plating such as corrosion resistance can be exhibited without impairing the brightness.
金属クロムが5mg/m2未満であると塗料密着性や魚肉食品
に対する耐硫化黒変性等が劣り、好ましくない。If the metal chromium content is less than 5 mg / m 2 , the paint adhesion and the blackening resistance to sulfidation of fish meat products are poor, which is not preferable.
更に金属クロム層の上層に耐食性等を向上するためクロ
ム水和酸化物３〜20mg/m2（Cr量として）を生成するも
のである。Furthermore, in order to improve the corrosion resistance and the like on the metallic chromium layer, 3-20 mg / m 2 (as Cr content) of hydrated chromium oxide is produced.
このように鋼板表面粗度が0.1〜0.5Raμｍで、その上層
にフリーSn0.2〜1.2g/m2生成して鏡面化し、その上層に
金属クロム５〜25mg/m2生成せしめて、金属クロムめっ
きとしての耐食性等の機能を付与し更にその上層にクロ
ム水和酸化物を５〜20mg/m2生成し、一層耐食性等を向
上するものである。In this way, the surface roughness of the steel sheet is 0.1 to 0.5 Raμm, free Sn 0.2 to 1.2 g / m 2 is generated in the upper layer to be mirror-finished, and metallic chromium 5 to 25 mg / m 2 is generated in the upper layer to form metallic chromium. A function such as corrosion resistance as plating is imparted, and 5-20 mg / m 2 of hydrated chromium oxide is further formed on the upper layer to further improve the corrosion resistance.

ク印刷においては顕著な効果が得られる。By printing on the surface of such a thin tin-plated steel sheet, the brightness is improved and beautiful printing can be performed. Particularly in metallic printing, a remarkable effect is obtained.
