ある。 It is known to utilize chromium to implement hydrophilic surfaces of offset plates. The chromium layer used in this case has the advantage of being excellent in durability and hydrophilicity, and in some cases having a beautiful appearance. In practice, the surface of such a chromium layer can be matte. In order to electrochemically obtain a chromium layer with a matte surface, there are two methods: using an electrolytic bath at a low temperature (for example, 5°C to 8°C), and using an electrolytic bath at room temperature (25°C to 35°C).
Two methods are known: a method using a temperature lower than 0.degree. C.) and a method in which the current is interrupted during the chromium deposition. However, in all known methods, the chromium layer (with bright or matte surface), which serves as the hydrophilic layer of the offset plate, must be thick (more than 1 micron, generally 1.5
It has been proposed to optionally deposit a chromium hydrophilic layer with a thickness of 1 micron or less on the support. However, such a very thin chromium hydrophilic layer does not serve as a durable hydrophilic layer. This is because the extremely thin chromium hydrophilic layer is highly sensitive and porous, presenting a surface with unacceptable properties for offset replication.
本発明の目的は耐久性に富み、オフセツト複製
に好適なオフセツト版を提供せんとするにある。 An object of the present invention is to provide an offset plate that is highly durable and suitable for offset duplication.

クロム層の厚さは１ミクロンよりも薄く、好まし
くは0.5ミクロンよりも薄いことを特徴とする。 The offset plate of the present invention comprises a known bright hydrophilic surface which can be used as its hydrophilic surface and is coated in at least one portion with a matt porous chromium layer, the chromium layer having a thickness of less than 1 micron. Characterized by being thin, preferably thinner than 0.5 micron.

はあるが最終材料表面を艶消しとするために利用
できるためである。 That is, the present invention deposits a very thin layer of matte chrome on a hydrophilic surface that can be used for offset, so that its relative porosity and brittleness are acceptable. The reason is that its lower surface, although hydrophilic, can be used to make the final material surface matte.
本発明を利用して艶消しとなしうる親水性表面

きる。 This is why non-oxidizing steel, tin/nickel alloys,
The chromium itself can be used to mattify the bright or semi-bright surfaces of hard materials such as chromium oxide surfaces (coating steel for certain storage boxes), nickel-phosphorus-tin alloys, and nickel alloys with a thin layer of chromium. can do.

みを艶消しとするだけである。 In some cases, the surface of soft, bright materials such as zinc or tin can be matte. However, in the case of such metals (especially tin), only the surface of a thin layer of tin (ie less than 1 micron thick) deposited on a hard surface becomes matte.

することができる。 To deposit chromium in a matt manner according to the present invention, known electrochemical techniques are utilized, either using a cold bath or by interrupting the electrical current during deposition. However, when depositing chromium on chromium or tin surfaces, room temperature (25
