図ったものとされている。2. Description of the Related Art A resin film-coated metal plate in which a resin film is laminated on the surface of a metal plate is used as a so-called decorative metal plate when a good appearance such as outer panel of home electric appliances, furniture, interior plate of building is required. It is mainly used for. A general resin film-coated metal plate of this type is a PVC resin film-coated steel plate (so-called PVC steel plate) laminated with a polyvinyl chloride (PVC) resin film on which an appropriate pattern is printed. As a resin film-covered metal plate, as shown in FIG. 5, a galvanized steel plate 1 is subjected to a chemical conversion treatment, and then a colored primer layer 2 with a colored primer paint and an overcoating paint 3 on the colored primer layer 2 are both rolled. A colored layer 4 is formed by coating with a coater and baking, and an ultraviolet curable coating 5 is coated on the entire surface of the colored layer 4 with a roll coater, and then a transparent polyester film 6 is coated on the ultraviolet curable coating. 5 and press it with the upper and lower rolls, and then irradiate with an ultraviolet irradiation lamp to pass the transparent polyester film 6 through the ultraviolet curable paint to give a purple color. Irradiating the line, the resin film-coated metal plate which is formed by performing an adhesion simultaneously with curing and transparent polyester resin film 6 of the coating film 5 of the ultraviolet curable coating has been disclosed (see Japanese Patent Laid-Open No. 3-38336). This resin film-covered metal plate is said to have a smooth coated surface in order to improve the appearance of the coating so as to improve the image clarity, that is, the specular gloss.

There are restrictions in various respects because it uses. For example, since it is necessary to transmit ultraviolet rays, the color tone of the transparent resin film that can be used is naturally limited.
Further, since the transparent resin film needs to transmit ultraviolet rays evenly, it is not preferable to print the transparent resin film. Further, the ultraviolet curable paint is optimally transparent or translucent, and in this case, the colored layer 4 needs to be visible through the coating film 5 of the ultraviolet curable paint. There are also restrictions in terms. From this, any color tone requested by the customer,
It is difficult to provide the appearance and pattern.

ての外観，模様柄の多様性をさらに得ることができる。A polyester resin film or the like is used as the transparent resin film which is adhesively laminated on the coated metal plate. As this transparent resin film, a so-called back-printed film having an arbitrary pattern printed on the back surface can be used. As a result, it is possible to further obtain a variety of appearances and patterns as a resin film-covered metal plate.

下変動を吸収して安定した外観を得るようにする。Lamination of the coated metal plate and the transparent resin film is carried out by passing between the pressed upper and lower rolls. In this case, a heating metal roll with a mirror-like surface (heat roll) as the upper roll that contacts the transparent resin film
It is desirable to use a rubber roll lined with silicone rubber as the lower roll that contacts the back surface of the metal plate. When a metal roll is used for both the upper and lower rolls, it is difficult to control the gap between the upper and lower rolls or the rolling force due to variations in the thickness of the metal plate, and it is difficult to obtain a uniform appearance. Therefore, as described above, a heat-resistant rubber lining roll that is generally used for laminating PVC resin films is used as the lower roll so as to absorb fluctuations in the rolling and obtain a stable appearance.

できる。The heating temperature of the heat roll is maintained at a constant temperature in the range from the heat distortion temperature of the transparent resin film to the melting point. Below the heat distortion temperature of the transparent resin film, the ironing effect of the heat roll is weakened, the smoothness and gloss of the surface of the transparent resin film cannot be obtained, and the image clarity is deteriorated. Even if the transparent resin film is printed, if it is a back print, the heat roll can improve the clarity of the transparent resin film without damaging the printed pattern.

鮮映性が低下する。The rolling force of the upper and lower rolls is 5 to 10 kg / c.
m 2 is desirable. If the rolling force is 10 Kg / cm 2 or more, the transparent resin film sticks out from the left and right ends of the metal plate and impairs the appearance, and after cooling, the transparent resin film-covered metal plate warps, impairing the product shape. If the rolling force is 5 Kg / cm 2 or less, the rolling effect on the transparent resin film is insufficient, the surface of the film becomes uneven, and smoothness cannot be obtained, resulting in poor image clarity.

生じ鮮映性が劣化するので，不適当である。Immediately after the metal plate having the transparent resin film adhered and laminated passes between the upper and lower rolls, cooling water is jetted from the back surface side of the metal plate to quench it. By quenching, the surface smoothness of the transparent resin film due to the reduction of the heat roll can be fixed as it is. If cooling water is sprayed on the surface of the transparent resin film to cool it, unevenness occurs on the film surface and the image clarity deteriorates, which is not suitable.

In addition, immediately after passing through the upper and lower rolls, cooling water is sprayed from the back surface side of the metal plate to rapidly cool it, and the final product is obtained while maintaining the smooth state of the transparent resin film, and high image clarity is secured.
