An alloy plated steel plate, a stainless steel plate, an aluminum plate, etc. can be used. Examples of the chemical conversion treatment of this metal plate include chromic acid treatment and phosphate treatment. The primer layer 2 is prepared by preparing a coating material composed mainly of an epoxy resin or a polyester resin containing 5 to 70% by weight of strontium chromate as a rust preventive pigment in a non-volatile resin component, rolling the coating composition, baking it, and drying it. Form to a dry thickness of ~ 8 μm. Regarding the mixing ratio of the rust preventive pigment, if it is less than 5% by weight, the corrosion resistance effect is lost, and if it exceeds 70% by weight, the coating property is deteriorated, so it is set to 5 to 70% by weight.

ある。The transparent fluororesin film 6 is adhered to the adhesive layer 5 by passing it between a pair of rolls and pressing the adhesive layer 5 in a high temperature state after the adhesive layer 5 is baked. Examples of the fluororesin film 6 include vinyl fluoride resin, vinylidene fluoride resin, trifluoroethylene chloride resin, trifluoroethylene / ethylene copolymer resin, tetrafluoroethylene / ethylene copolymer resin, tetrafluoroethylene / Hexafluoropropylene copolymer resin, tetrafluoroethylene
Perfluoroalkoxyethylene copolymer resin, tetrafluoroethylene / perfluoroalkyl vinyl ether copolymer resin, tetrafluoroethylene resin, etc. are used. Of these, a tetrafluoride-based fluororesin film is suitable for use because it is excellent in stain resistance, chemical resistance and non-adhesiveness.

When the thickness is less than 5 μm, the original functions of stain resistance and chemical resistance become insufficient, wrinkles easily occur during lamination, and it is difficult to manufacture a uniform thickness. On the other hand, when it exceeds 30 μm, the workability is deteriorated, and it is sufficiently high in view of the functions of stain resistance and chemical resistance, resulting in cost increase.

したとき、とくに有意義である。According to the film-coated metal plate of the present invention, the colored resin coating film layer 3 is formed on the surface of the metal plate 1, and the transparent fluororesin film 6 is bonded onto the colored resin coating film layer 3. Since it is adhered via the agent layer 5, unlike the conventional type in which a fluororesin coating film is formed by coating, the film 6 does not become porous at the time of production and is excellent in stain resistance and chemical resistance. It is also excellent in non-adhesiveness against foods such as soy sauce and sauce. Moreover, when the fluororesin film 6 is made of a tetrafluorinated fluororesin, it is particularly excellent in stain resistance, chemical resistance and non-adhesiveness. Therefore, it is particularly meaningful when applied to a range hood that is easily soiled with oil and an interior material around the kitchen.

きる。The fluororesin film 6 of the present invention is transparent itself, and the colored resin coating film layer 3 is formed through the film 6.
By looking at it, the color is used for decoration. When the printed layer 4 having a wood grain pattern or the like is formed on the colored resin coating layer 3, the pattern of the printed layer 4 is viewed with the color of the colored resin coating layer 3 as the ground color. This is
In the case where the colored film is laminated on the outer surface of the metal plate 1, it is necessary to prepare a large number of colored films of different colors and keep them in stock, which is troublesome in inventory control and the thickness of the colored film is large. It is necessary to mask so that the color of the plate 1 is not transparent, but in the present invention, it is 5 to 30.
It suffices to prepare a transparent fluororesin film 6 having a thin film thickness within the range of μm, and inventory management of the film 6 can be easily performed, which leads to reduction of manufacturing cost as a whole. Since the color change for decoration only needs to change the color pigment of the colored resin coating layer 3, this can be dealt with well.
