題があった。Hitherto, as a typical interior decoration material such as wallpaper, a material having a structure in which a resin layer such as a polyvinyl chloride resin layer is formed on a base material has been used. However, the decorative material having such a configuration has poor moisture absorption and desorption properties, and it is not possible to converge the change in humidity inside the building to a lesser degree with respect to changes in temperature and humidity in the outside world. Rather, the change in indoor humidity greatly increases as compared with a decorative material that is itself made of a material having moisture absorption and release properties, such as traditional wall clay and wood (particularly paulownia wood). In particular, if the humidity fluctuates in the direction of increasing humidity, not only does the discomfort index increase, but also condensation occurs on the surface of the decorative material and, if the wall is hollow, inside the hollow, causing mold and corrosion and rust on the building material. There was a problem that would occur.

It is characterized by comprising a moisture-absorbing / releasing resin layer 1 in which a void is formed in at least a part of the periphery of the moisture-absorbing / desorbing material particles by axial stretching or biaxial stretching. Then, as shown in FIG. 2, a configuration in which the hygroscopic resin layer 1 is laminated on the base material 2 may be employed. Further, as shown in FIG. 3, the voids in the moisture-absorbing and releasing resin layer 1 may be cellular foams communicating with each other.

At room temperature (the temperature at which the interior decoration material is used, that is, the normal indoor environment temperature. Since the temperature rises due to sunlight coming in through windows, the temperature is higher than the ambient temperature, usually up to about 80 ° C.)

Examples include polyethylene, polypropylene, polyolefin resins such as ethylene-propylene-butene 1 copolymer, and polyvinyl chloride. Among these resins, the resin itself has a certain degree of moisture absorption / desorption properties, is well compatible with the moisture absorption / desorption material particles, and has good dispersibility of the moisture absorption / desorption material particles, so that the amount of addition can be increased. For this reason, it is preferable to use an ethylene / vinyl acetate copolymer or a saponified product thereof.
Note that a mixed resin of an ethylene / vinyl acetate copolymer and an acrylic resin can also be used.

することがないため、より好ましい方法である。When the decorative material has a single-layer structure of a moisture-absorbing / releasing resin layer, these resins are formed into a film by an inflation method, a calender method, an extrusion method, a casting method, and the like, and a stretched layer is used. When the decorative material is a laminate of a base material and a moisture-absorbing and releasing resin layer, a film is formed in advance, and the stretched layer is bonded and laminated to the base material with an adhesive or heat fusion. In any case, the film-forming methods such as the inflation method and the calendering method, in which the heated molten resin containing no water is cooled and solidified to form a film, have more active water and organic components than the casting method using a coating method. The resin component and the moisture-absorbing / desorbing material particles are separated and settled before being adsorbed by the moisture-absorbing / desorbing material particles such as white clay or solidified in a paint (liquid) state, and the effect of the moisture absorbing / desorbing resin layer is reduced. This is a more preferable method because it is not performed.

６０Å程度のものが吸放湿効果の点で良好である。As the moisture absorbing / releasing material, a material composed of solid particles is used. As the material, various known materials can be used. For example, inorganic materials such as activated clay (montmorillonite), ettringite, tobermorite, shells such as scallop, or organic materials such as saponified graft copolymer of starch and acrylonitrile, cross-linked polyvinyl alcohol, rice hull, wood flour, etc. Is used. The amount of the moisture absorbing and releasing material particles is about 5 to 200 parts by weight based on 100 parts by weight of the resin. Among these, activated clay (montmorillonite) is particularly preferred as the moisture absorbing and releasing material. Activated clay particles do not dissolve in or swell with water, and do not deteriorate or mold during prolonged exposure to air, and can repeat the cycle of moisture absorption and desorption. . The particle size of the activated clay used is about 0.1 to 100 μm. Further, in order to maintain the relative humidity at 40 to 60% RH, the average pore diameter is 10 to 10%.
Those having an angle of about 60 ° are good in terms of the moisture absorption / release effect.

等の方法による。As shown in FIGS. 1 and 2, the moisture absorbing / releasing resin layer may have a structure in which voids (or bubbles) between the resin and the moisture absorbing / releasing material formed inside by stretching are mutually independent. 3
As shown in the above, a cellular structure having a passage in which a number of internal voids communicate with each other may be used. In any case, the thickness of the moisture absorbing / releasing resin layer is usually about 50 to 300 μm. In any structure, those having a large number of voids opened on the surface have good air permeability, and therefore have good moisture absorption / release properties. That is, in such a structure, the moisture absorbing / releasing material particles are efficiently brought into contact with the outside air. In order to form a cellular structure as shown in FIG. 3, it is necessary to add a known thermal decomposition type foaming agent such as azodicarbonamide and heat-foam the formed moisture-absorbing / desorbing resin layer, and then stretch it. Alternatively, a method is used in which voids around the hygroscopic particles generated by stretching are interconnected.

てもよい。[0010] The voids opening to the surface are voids communicating from the inside of the resin layer to the surface of the resin layer. It is preferable that such a plurality of voids communicate with each other and the communicating voids are distributed to the inside of the resin layer because the moisture absorption / release effect is good. Voids may communicate from the front surface to the back surface of the resin layer. In this case, particularly when the base material is a moisture-absorbing and releasing material such as paper, moisture absorption and desorption between the substrate and the outside air can also be used. Needless to say, a void that is not opened on the surface may exist in parallel with a void that is opened on the surface.

を構成する樹脂で構成される。The void around the moisture-absorbing / desorbing material particles only needs to be formed at least partially around the moisture-absorbing / desorbing material particles. The diameter of the void body is usually in the range of about 1 to 1000 μm.
The void body may be directly opened on the surface of the resin layer, or may be connected to the surface of the resin layer by a passage.
The diameter of the passage is also in the same range as the diameter of the cavity body.
The shape of the void body may be a sphere, a spheroid, a polyhedron, or other various shapes. The cavity body and the wall surface of the passage are made of a resin constituting a resin layer.

ら延伸倍率は１．５〜３．０倍が好ましい。The voids in the moisture-absorbing / releasing resin layer are formed by a method of uniaxially or biaxially stretching the moisture-absorbing / releasing resin layer formed in advance by the above-described method. Due to the shearing stress between the resin and the moisture-absorbing / desorbing material particles dispersed in the moisture-absorbing / desorbing resin, the interface is separated, and a part of the moisture-absorbing / desorbing material particles is exposed on the surface. And the structure as shown in FIG. Although the degree of stretching, the moisture absorption / release material is exposed on the film surface, and good moisture absorption / desorption performance is obtained, the film strength decreases, stretching unevenness, the stretch ratio is determined from the content of the moisture absorption / release material per unit volume. 1.5 to 3.0 times is preferable.

May penetrate. In some cases, the back surface may be moistened, warped, corroded, or moldy or rusted due to moisture permeating the back surface. Therefore, when it is necessary to prevent this phenomenon, polyethylene, polypropylene,
It is preferable to form a moisture-proof / water-proof layer such as polyvinylidene chloride and silica-deposited polyethylene terephthalate. FIG. 4 shows an example of an interior decorative material in which a moisture-proof / water-proof layer 3 of this type is formed on the back surface of a base material 2. The thickness of the moisture-proof / waterproof layer 3 is about 30 to 100 μm, and is formed by bonding with an adhesive such as a two-component curable urethane resin or by applying by a melt extrusion method (extrusion coating method) or the like. .

As the decorative layer, for example, there are a picture print layer provided by a known ink and printing method, a metal thin film layer of aluminum or the like. In this case, it is preferable to provide a part instead of the entire surface. In addition, a decorative effect can be obtained by adding a known dye or pigment to the inside of the resin layer and coloring the resin layer within a range that does not impair the moisture absorption / release properties. Alternatively, the surface of the resin layer may be embossed with a concavo-convex pattern, or the embossed concave portions may be filled with a coloring ink by a wiping method and colored.
