As described above, stain resistance in order to make metal plate etc. improves etc., is studying and include in metal sheet surface formation
The film of inorganic material.However, being easy to produce interference fringe if being formed in metal sheet surface than relatively thin film.Another party
Face, if increasing the thickness of film, the design of metal plate is easy impaired.In addition, for previous coated metal plate, for
The considerations of to the viewpoint of stain resistance etc., with uniform thickness and is flecklessly formed with film on a metal plate.
In contrast, present inventors found that, by discontinuously forming film, it is not likely to produce interference fringe, and send out
It is existing, if it is substantially comprising with composition formula K2O·xSiO2The film for the composition that (3.5≤x < 6.8) indicate, even if not connecting then
It is continuous, it can also obtain sufficient stain resistance.
Even if the film for covered metal plate is discontinuous, the mechanism of stain resistance is also embodied, it is contemplated that be as follows.It is right
In the film comprising above-mentioned composition, potassium is in the micro dissolution in surface.Moreover, potassium ion is hydrated with the moisture in atmosphere, inhale
Draw the moisture in atmosphere.As a result, the not only forming region of film, the even region between film, i.e. metal plate exposing
Region is also covered by thin moisture film.Therefore, dirty even if being attached with the greases such as sebum or oil-based ink in coating metal plate surface
Dirt also becomes the state floated on moisture film, can easily remove dirt by wiping etc..
In addition, in general, if dirt is attached to after coating metal plate surface through after a period of time, a part of dirt at
Divide and infiltrated sometimes into film or metal plate, the removing of dirt becomes difficult.In contrast, for the coating gold in the present invention
