あるので、化成処理条件が限定されている。In recent years, with the increasing quality of home appliances, audio equipment, kitchen equipment, interior building materials, etc., there has been an increasing demand for painted steel sheets with good design, especially sharpness. Therefore, nine different types of research have been conducted, and in order to obtain a coated steel plate with high image clarity,
! J-1686, JP-A-63-60224 discloses a method for smoothing the surface of a steel plate to be painted. To do this, the surface roughness of the steel plate, Ra, must be set to 0.2μ.
It must be less than m. The surface roughness of the steel plate is 0.2 μm.
In order to achieve the following, adjustment is performed using rolling rolls, but in order to obtain uniform smoothness, rolling rolls must be replaced more frequently, which worsens economic efficiency. On the other hand, if the surface of the T14 plate is made smooth, a sufficient anchoring effect of the paint cannot be obtained during painting.
Paint adhesion tends to decrease, and the scrunch resistance of the paint film is poor. In order to improve paint adhesion, chemical conversion treatments such as chromate treatment and phosphate treatment as pre-painting treatments tend to etch the steel plate surface and impede its smoothness, so chemical conversion treatment conditions are limited. .

Therefore, there is a need for an improved method for producing a resin-coated metal sheet that does not impair paint adhesion, is economical, and has high image clarity, rather than the known method from the surface of the steel sheet.

A in FIG. 1 is the outermost layer of the resin-coated metal plate, which is a transparent thermoplastic or thermosetting resin film having a thickness of 5 to 1100 Ij. When the thickness of the film is less than 5 μm, the image clarity is poor and it is difficult to handle the film during coating. When the thickness exceeds 100 μm, the effect on image sharpness is saturated, resulting in poor economic efficiency. In order to improve the scratch resistance during molding and handling of resin-coated metal plates, the surface layer of the outermost layer A of the film in Figure 1 is coated with silicone-based, fluorine-based, acrylic-based, or melamine-based baking molds or ultraviolet rays. The irradiation type paint can be coated to a thickness of 1 to 5 μm.

が含まれる。On the other hand, when it becomes soft to 7B or less, it is effective in improving image clarity, but when it is made into a resin-coated metal plate, the moldability deteriorates. Furthermore, when the I'X depth of the thermoplastic resin is less than 5 μm, the image clarity deteriorates, and when it exceeds 50 μm, the effect tends to be saturated, the economy is poor, and the moldability tends to be poor. The thermoplastic resin layer may be colored with a pigment, or may be formed from either a paint or a film. If a paint system is used, it is applied to the film of FIG. 1A and dried. In the case of a film, it may be laminated on the surface of the film shown in FIG. 1A by extrusion molding as shown in FIG. 1C, or it may be dry or hot laminated using an adhesive. The paint or film in Figure 1C includes polyethylene polypropylene, polystyrene polyvinyl chloride, polyvinyl acetate, polyacrylate, polymethacrylate, polyvinylchloride polyacrylconitrile, polyether, polycarbonate, polyester, and polyurethane resins.
