作業的困難を伴うものであつ１こ。In the past, aluminum plates were generally used as supports for lithographic printing plates, but as aluminum plates have become extremely expensive in recent years, attempts have been made to use them repeatedly. However, the aluminum plate is soft and deforms when handled, so it is difficult to use it repeatedly.

のである。In the case of an aluminum plate, the image-receiving layer, such as a photosensitive layer, has excellent adhesion, hydrophilicity, water retention, and corrosion resistance. Oxidation treatment? However, the plate-making process is complicated and the cost is high. Based on the L-5 findings, the metal layer interface of a galvanized steel sheet made from iron-zinc metal has characteristics similar to the surface of an aluminum sheet that has been anodized after graining. This associative zinc is
Next, the above-mentioned drawbacks were solved by applying it to steel plates (4).

ート系化成皮膜に向上させろ。When zinc or its agglomerates are subsequently heat-treated by hot-dip plating or electroplating on a steel plate, heat diffusion occurs between the metal plating layer and the steel cable base, and the plating layer becomes iron-zinc bound up to the interface. Be it. This adhesion plating layer is dense, has a surface roughness of an appropriate thickness, has high hardness, and although it is inert, it contains iron.
Synthetic resins such as polyvinyl alcohol have a good affinity for (・. Therefore, corrosion resistance is 7 times less (・) and has performance equivalent to or better than that of anodized aluminum plates, and is suitable for graining and anodizing. In addition, since it is a steel plate in terms of strength, it is more susceptible to deformation than an aluminum plate.
・There is a problem with corrosion, so this invention should be improved to a chromate-based chemical conversion coating.
以下本発明の詳細な説明する。The present invention will be explained in detail below.

The plating layer 2 is alloyed by thermal diffusion, and its surface roughness is dense as shown in Figure 2 (al). , lightly rolled with a roll, etc., and removed as shown in Figure 2 (bl) to reduce the surface roughness to 4 to 7.
It is preferable that the surface be 1 mm. If a very dense surface is required, graining may be applied.

However, there is no problem (・For example, if the plating is done by hot-dip plating, it will contain about 0.05 to 0.50% aluminum1, and if it is electroplated, it will contain aluminum, cobalt, nickel, titanium, etc.). Although it may contain several percent of corrosion resistance improving elements, there is no problem as a support even if these elements are contained.

・I prefer things.・The chromate film has good adhesion to resin and has hygroscopicity (7), so it has good affinity with water and excellent water retention (.Therefore, adhesion is required after plate making. This is convenient for the painted scarlet area and the non-printed area that requires water retention.

The interface between the second and second layers is anodized after graining, and has performance equivalent to or better than that of aluminum plates. Therefore, the price is lower than that of aluminum plates, and it is also easy to handle (- less likely to deform). Because of this, it can be used repeatedly, resulting in a significant cost reduction.Also, since graining and anodic oxide coating are not required during plate making, costs are also reduced from this perspective.
