From such a viewpoint, a method of internally adding and retaining a moisture-absorbing filler to a porous material as a room humidity adjusting material is known. However, when this is used as an indoor interior panel, not only does the filler fall off when the panel is transported or mounted, but if a wet cloth is used to wipe off the dirt, the dirty moisture once absorbed by the cloth will be lost again. There was a drawback that the material was sucked and stains were formed. Some dew-prevention wallpapers and the like have a dew-prevention function, but when applied as a wallpaper material, a great effect could not be expected.

ましくない。As the anodic oxide film of aluminum to be filled with the above-mentioned functional substance, the pore diameter of the porous anodic oxide film formed by ordinary anodic oxidation treatment is generally about 50 n.
m or less, and it is difficult to fill most of the functional materials, so it is necessary to use aluminum having a porous anodic oxide film having a large pore diameter. Various methods are known as a method of forming such a porous anodic oxide film having a large pore diameter.First, in one method, aluminum is converted into, for example, sulfuric acid, phosphoric acid, oxalic acid, malonic acid, One or two of a mineral acid such as maleic acid and / or an organic acid
More than one kind of acid aqueous solution, for example, phosphoric acid 5-30 W / V%,
Anodizing is performed at a high voltage in an electrolytic bath containing 3 to 40 W / V% of oxalic acid to form a porous anodic oxide film having a diameter larger than a normal pore size on the surface of the aluminum. Generally DC
When anodic oxidation is performed at a high voltage of 150 V to 220 V, an anodic oxide film having a pore diameter of usually 120 nm or more is obtained, so that most of the functional substance can be deposited and filled in the pores. That is, if the voltage of the anodic oxidation treatment is less than 150 V, it is not preferable because it is difficult to obtain pores large enough to precipitate and fill the functional substance. On the other hand, if the voltage exceeds 220 V, the physical properties such as the strength of the anodic oxide film are reduced. It is not preferable because it has an adverse effect.

Further, in order to shorten the time required for the process of enlarging the pores of the film, the immersion and the alternating current electrolysis are alternately repeated at short intervals in an aqueous solution of phosphoric acid of 3 to 10 W / V%, so that the film thickness is reduced. The hole enlargement process can be performed in a relatively short time.

For example, an aqueous dispersion bath is prepared by expressing polarity on the surface of the functional substance particles (eg, adsorbing a surfactant on the particle surface) and dispersing 10 to 30% of the functional substance particles in an aqueous solution. In this bath, an electrophoresis method may be adopted in which a DC electrolysis (voltage: 30 to 200 V) is performed using the aluminum porous body as an anode and the pores of the anodic oxide film are filled with functional substance particles. As the electrophoresis method, a DC voltage scanning method in which a DC voltage is scanned from a low voltage to a high voltage at a constant step-up rate for a predetermined time, a DC constant voltage method in which electrolysis is performed at a constant voltage for a predetermined time, and the like can be adopted.
