法を第２の発明とする２つの発明よりなるものである。The method for producing an aluminum alloy for printing according to the present invention includes (
1) An aluminum alloy containing MB 0.3-g% by weight and the balance consisting of aluminum and impurities is subjected to final cold rolling at a rolling rate of 10% or more to obtain an aluminum alloy plate, and this aluminum alloy plate is treated with a nitric acid-based electrolyte. The first invention is a method for producing an aluminum alloy for printing, which is characterized by subjecting the aluminum alloy to electrolytic surface roughening treatment using an alternating current.
) An aluminum alloy containing 0.3-5% by weight of MB, 1,05-1% by weight of Cu, and the balance consisting of aluminum and impurities is subjected to final cold rolling at a rolling ratio of 10% or more to obtain an aluminum alloy plate. This invention consists of two inventions, the second invention being a method for producing an aluminum alloy for printing, which comprises subjecting this aluminum alloy plate to an electrolytic surface roughening treatment using alternating current in a nitric acid-based electrolyte. .

合および電解粗面化処理法を詳細に説明する。Hereinafter, regarding the method for producing an aluminum alloy for printing according to the present invention, the components and proportions of the aluminum alloy used and the electrolytic surface roughening treatment method will be explained in detail.

二重構造ピントの形成効果は飽和しかつ経済的にも無駄
であると共に圧延板の製造法に種々の問題が発生するこ
とになる。よって、ｈ録含有景は（）、３〜５重景重量
する。The llI record uses an electrolytic cutting process using alternating current in a nitric acid electrolyte to form a deep and extraordinary primary focus and a secondary focus with multiple IL irregularities on the pit surface, that is, a double structure focus. If the M8 content is less than 3% by weight, double structure pits cannot be formed, and if the M8 content exceeds 5% by weight, double structure pits cannot be formed. The forming effect is saturated, it is economically wasteful, and various problems arise in the method of manufacturing rolled plates. Therefore, a scene containing an h record () weighs 3 to 5 double scenes.
Ｃｕは電解粗面化によるエツチング効果を高くするため

有量としては０．１〜０．５重量％である。Cu is an effective element for enhancing the etching effect by electrolytic surface roughening and for adjusting the focus, especially the shape of secondary pits, and such effects are sufficiently obtained when the content is less than 0.05 mm. Also, 1% by weight
If the content exceeds the above range, dissolution due to electrolytic surface roughening will be excessive, which is not preferable. Therefore, the Cu content is 0,05~1
Weight%. The desirable content is 0.1 to 0.5% by weight, taking into account corrosion resistance.
不純物については、通常市販の工業用純アルミニウムに

０．７重量％までは含有されてもよく、Ｓｌは０．３重

有量は０．０５重重景以下とするのが良く、望ましくは
０．０２重量％以下とするのがよい。Regarding impurities, there is no problem as long as they are contained in commercially available industrial pure aluminum, but Fe may be contained up to 0.7% by weight, and Sl exceeds 0.3% by weight. Since unetched areas tend to appear easily during electrolytic surface roughening treatment, the content is set to 0.3% by weight or less. In addition, the content of Ti for refining the foundry area is Al.
- Ti particles and/or Ti-8 particles tend to aggregate, resulting in a non-uniform rough surface due to electrolytic surface roughening treatment, so the Ti content is preferably 0.05 or less, preferably 0. The content is preferably .02% by weight or less.

が困難となる。At this time, it is necessary to set the rolling ratio of the final cold rolling to 10% or more, which means that the aluminum alloy plate for printing requires a great deal of manual handling during the plate-making and printing processes. In soft phases such as 0 materials, σ8, σ0.
Even if the absolute value of 2 etc. is high, especially when the thickness is made thin, problems with λ handling such as buckling may occur, making it difficult to put it to practical use.
なお、この点再現性など確実にこの目的を達しようとす

マットの除去を行なう方法が広く採用されている。However, prior to electrolytic surface roughening, the aluminum alloy plate is subjected to surface treatment to remove rolling oil from the surface and to clean the surface of the aluminum alloy plate, if necessary. Generally, a treatment method is used to remove rolling oil by cleaning the surface of the aluminum alloy plate using a solvent such as trichloride or a surfactant, and the cleaning rate of the aluminum alloy plate surface is 1 to 10%.

がある。The aluminum alloy plate treated under the above conditions was desiccated and then neutralized by immersing it in an aqueous alkali or acid solution at a temperature of room temperature to 80°C for 1 to 50 minutes according to a conventional method, if necessary. Used as a support for post-printing plates. In addition, when using the aluminum alloy plate as a support for printing plates, it is said that if the rough surface of the aluminum alloy plate is further anodized using a conventional method, it will become more hydrophilic than the aluminum alloy base state, making it easier to print and improving printing durability. effective.
