[0005]

SUMMARY OF THE INVENTION The present invention provides an iris color pigment by combining a specific back pigment, that is, a layer containing the iris color pigment of the present invention, with a specific back surface. The present inventors have obtained a completely unpredictable new finding that the color of the pigment-containing layer changes in accordance with the change in the direction of incident light and the direction in which the light is viewed. Was.

That is, the present invention relates to a building material comprising a back layer and a variable iris layer laminated in this order on at least a part of a substrate, wherein the color of the back layer is light, and The variable iris color layer comprises at least an iris color pigment as a component thereof, and the direction of light incident on the variable iris color layer on the back layer or the variable iris color on the back layer is changed. Depending on the change in the direction of the observation means for optically observing the colored layer, the variable iris layer is observed to have a predetermined glossy color or to be observed in a state in which the glossy color has substantially disappeared. A variable iris color building material, and a building material in which a variable iris color layer is laminated on at least a part of the base material, wherein the variable iris color layer is in contact with the variable iris color layer of the base material. The color of the portion is a glossy light color, and the variable iris color layer is At least the iris Iropa as forming component -
Change in the direction of light incident on the variable iris layer on the substrate, or the direction of observation means for optically observing the variable iris layer on the substrate. The variable iris color layer is observed to have a predetermined glossy color or the glossy color is observed to be substantially extinguished according to the change of the variable iris color building material. About.

As described above, the present invention is most characterized by combining a specific back surface with a variable iris color layer containing a specific iris color pigment. By taking a specific configuration, the color of the layer changes according to the change in the direction of the incident light or the viewing direction, thereby providing a decorative material having a dynamic design. It is something to offer.

Hereinafter, the present invention will be described in more detail.

As the base material of the building material of the present invention, it is needless to say that all conventionally known materials used for this kind of application including various kinds of papers and synthetic resin sheets can be applied. Rather, it should be understood that a wider range is included than the narrow substrate used in the past.

That is, the base material of the present invention is formed, for example, on one surface of paper or a synthetic resin sheet (the surface on which a variable iris color layer or the like to be described later is laminated) by further adding vinyl chloride sheet or PET. Laminated synthetic resin sheets such as sheets, and vinyl chloride paper which may contain a foaming substance (volume expanding component)
A coating layer or a foamed layer formed by coating an aqueous solution of a stsol or synthetic resin, or an adhesive layer or an adhesive layer containing an adhesive substance or an adhesive substance on the other surface. It includes those provided, as well as those provided with a release sheet for preventing those layers from being inadvertently stuck to other substances before actual use.

Next, the back layer in the building material of the present invention is:
This layer is formed by lamination on the entire surface or on a portion of the base material, and is a layer to be present below the variable iris color layer on the base material.

As will become clear from the detailed description of the variable iris layer described later, the back layer has a basic function of causing the glossy color of the variable iris layer to appear or disappear. In order to achieve the above, it is necessary to have a light color.

The "light color" in the present invention, as will be described later, not only excludes pure black, but it is difficult and impossible to define / limit the color density with a constant numerical value. This means that the variable iris layer described later is included in the "light color" of the present invention as long as it has a function of showing or eliminating its glossy color. For example, beige color,
Examples include cream color, light gray, light red, light blue, light green, and light purple, but even if the light color is further lighter or conversely recognized as dark, the variable rainbow As long as the coloring layer exhibits the above function, it corresponds to the light color in the present invention.

Such a back layer is selected from, for example, white or extender pigments such as titanium oxide and barium sulfate, general dyes, white pearl pigments, silver pearl pigments, aluminum powder, silver powder and the like. Each of these is used alone or in combination of two or more, for example, a known aqueous or oily ink composition containing a synthetic resin, or a paste sol containing a coloring component. can do.

As the above-mentioned synthetic resin, those which are glossy and excellent in transparency after lamination are preferable, and examples thereof include vinyl chloride resin, ethylene-vinyl acetate copolymer resin and ethylene-acrylate ester copolymer. Polymer resins, acrylate resins, chlorsulfonated polyester resins, chlorinated polyolefin resins, saturated polyester resins, polyamide resins, polyurethane resins, isocyanate resins, styrene-butadiene rubber, nitrile-butadiene rubber, and the like. Yes, but not limited to.

A method of forming a back layer on a substrate using an aqueous or oily ink composition containing these synthetic resins and the above-mentioned coloring components, or a paste sol, is known in the art. Any of them can be adopted and is not limited at all. Examples include knife coating, air-knife coating, gravure coating, reverse coating, roll coating, bar coating, and spray coating. Law,
Various coating methods, such as a flat screen method and a rotary screen method, and a printing method are exemplified.

The white pearl pigment or the silver pearl pigment mentioned as the above-mentioned coloring component is a so-called pearl pigment which is a pigment other than the iris pearl pigment described later in the present invention.
When these are used as one of the coloring components, the color of the back layer becomes almost the same as the state when the glossy color of the variable iris layer disappears, and therefore, it is mentioned as a particularly preferred embodiment. be able to.

If aluminum powder or silver powder is used as one of the coloring components, even if the base material is colored dark or a pattern is provided in advance, These can be efficiently concealed, exhibiting a preferable light color as the whole back layer, and also have excellent glossiness, and thus can be cited as an example of a preferred embodiment. Further, the back layer of the present invention can be formed by laminating two or more layers, and in this case, any one of a white pearl pigment and a silver pearl pigment is used as the upper layer located on the variable iris color layer side. When at least one of the coloring components is used, and on the other hand, as a lower layer located on the side of the base material, at least one of aluminum powder and silver powder is used as the coloring component, the respective coloring components have the above-described properties. Since preferred effects are expressed as a synergistic effect, it is a particularly preferred embodiment.

Next, the variable iris layer of the present invention will be described.

The variable iris layer contains at least an iris pearl pigment as a constituent thereof, and is laminated on the back layer provided on the base material or has a glossy base material color. If it is a certain light color, it is provided directly on it. The most important feature of the present invention resides in the combination of the variable-color iris layer and a specific back surface such as a back layer.

The iris pearl pigments referred to in the present invention mean a group of pigments having the following specific properties in a series of so-called pearl pigments obtained by coating flake particles such as mica with titanium oxide or the like. I do.

That is, when the color of a layer containing the pigment in a transparent medium is a specific black color such as yellow, red, purple, blue, or green when the base provided in contact with the layer is pure black. It exhibits a color, but when the base is pure white, its glossy color is extremely lightened or disappears. This property is probably related to the thickness of the coating layer coated on mica or the like.

The variable iris color layer contains an iris pearl pigment having such properties as at least a constituent component thereof, and can be combined with a specific back surface such as a back surface layer (in other words, such a specific back surface layer). By being present on the back surface), a very specific property that is unprecedented is exhibited.

That is, a change in the direction of light incident on the variable iris color layer, or a change in the direction of the observation means (for example, the human eye, a camera, a video camera, etc.) for optically observing the variable iris color layer. Depending on the change, the variable iris color layer is observed to have a predetermined glossy color (the above-described glossy color when the base is black), or the glossy color is substantially disappeared (extremely light color). (Including the case where it is converted into a compound).

Such a change in gloss color may be caused only by a change in the direction of incident light with respect to the variable iris color layer, or may be caused only by a change in the direction of the observation means with respect to the variable iris color layer. Or, of course, it is caused by both changes. For this reason, the color and the pattern may be different between a case where the user looks directly at the camera and a case where the user sees the mirror. The glossy color of the variable iris layer also exhibits the above-described changes depending on the presence or absence of incident light or the change in the intensity of each incident light when a plurality of lights are incident.

However, the detailed mechanism of why such a specific color change is exhibited only when the variable iris color layer is combined with a specific back surface has not yet been elucidated. .

The variable iris layer is made of a transparent (preferably colorless and transparent) resin such as various synthetic resins by using the iris pearl pigments described above alone or in combination of two or more.
It can be formed by being dispersed in a medium. Specifically, examples thereof include an aqueous or oily ink composition containing the iris pearl pigment as described above and a synthetic resin, or various paste sols. As the synthetic resin used here, for example, various synthetic resins used for forming the back layer can be suitably used.

In the present invention, as the specific back surface combined with the variable iris color layer, when the base material itself is a glossy light color, the base material itself constitutes the back surface together with the back surface layer. What can be done is as described above.

In this case, "light color" means the same content as the "light color" in the back layer.

As an example of such a base material, for example, the base material itself is colored by the same kind as the coloring component constituting the back layer, or the base material itself is inherently In the case where the color has a light color, it corresponds to the state as it is. Alternatively, the surface on the side on which the variable iris color layer is provided on the substrate is formed by metal deposition by a known metal deposition method, or is formed by coating a synthetic resin as described above by a known coating method. And the like.

Further, these substrates may be subjected to a calendar treatment so that the surface on the side on which the variable iris color layer is provided has a smooth and glossy state. Thus, when the surface on the base material is smooth and glossy, the change in the color of the variable iris layer becomes more conspicuous as described above, and this is a preferred embodiment of the present invention.

The building material of the present invention basically has the structure as described above. In order to further enhance the design effect, the following embodiments can be mentioned.

First, when the variable iris color layer is provided in a pattern on the specific back surface as described above, the color changes in the pattern. In addition, the variable iris color layer having substantially the same color as that of the variable iris color layer is laminated on the upper and lower arbitrary portions of the variable iris color layer, or the variable iris color layer is formed to be partially thick, so that the variable iris color layer is formed. When observed in a state having a predetermined gloss color, the pattern due to the laminated portion or the thick portion is hardly recognized. On the other hand, when observed in a state in which the gloss color has disappeared, the laminated Since the parts and the like appear in the shape of a design pattern (as if they are raised), it is possible to configure a variety of design patterns.

As coloring components, ordinary dyes and pigments, fluorescent pigments, luminous pigments, thermochromic dyes,
The coloring layer is further formed by an ink composition or paste sol having the same formulation as that for forming the variable iris color layer and the back layer except that a conventionally known coloring agent such as a photochromic dye is included. When provided, the coloring effect of the colored layers is separately added together with the color change by the variable iris color layer, so that a further variation can be added to the design effect.

On the other hand, as a coloring component in such a colored layer, by using the coloring component used for forming the back layer together with or in place of the coloring agent as described above, If the color is laminated on an arbitrary portion on the variable iris color layer as being substantially the same as the specific back surface, when the variable iris color layer is observed in a state having a predetermined glossy color, the coloring layer becomes a design pattern The color of the colored layer and the color of the specific back surface are substantially the same, so that the glossy color of the variable iris color layer has disappeared. When it is observed, the design by the colored layer can be eliminated at the same time, and a surprising design effect is provided.

In each layer of the variable iris color building material of the present invention, a fragrance and an insect repellent may be used, if necessary, as long as the color (gloss color) changing function of the variable iris color layer of the present invention is not impaired. , Repellents, antibacterial agents, deodorants, heat-expandable capsules, adsorbents, ultraviolet absorbers, antioxidants, optical brighteners, surfactants, defoamers, fungicides, deodorants, waterproofers , Water repellent, flame retardant, humectant, heat insulator, glass beads, retroreflective agent,
Any agent such as a thermosetting resin, a crosslinking agent, a catalyst, a plasticizer, a stabilizer, and a lubricant may be added.

The variable iris building material of the present invention has a laminated structure as described above. However, even if an additional layer other than this is provided, the variable iris building material of the present invention can be used. It does not deviate from the gist, and may be subjected to heat foaming treatment or embossing treatment.

Examples of such additional layers include a primer layer provided between the substrate and the back layer or the variable iris layer, and a protective layer provided on the back layer or the variable iris layer. However, the present invention is not limited thereto.

Specific applications of the building materials targeted by the present invention include, for example, wallpaper and other wall covering materials, flooring materials (floor materials), sealing materials (ceiling materials), decorative boards for furniture and interior goods, Examples include vehicle interior materials, but are not limited thereto.
