DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative material such as a decorative plate, and more particularly to a decorative material in which a pattern can be seen in darkness.

[0002]

2. Description of the Related Art Conventionally, decorative materials such as decorative plates and decorative sheets obtained by printing a pattern on a substrate such as a resin plate, a wooden plate, a metal plate or the like, or a base material such as a resin sheet have been used. Used in applications. For example, as a decorative plate used for a refrigerator or the like, a decorative steel plate or the like in which a pattern is printed by gravure offset printing or the like on an iron plate whose surface is plated is used.

[0003]

However, in the case of conventional cosmetic materials, since the pattern of the printed pattern layer is formed on the assumption that the pattern is viewed in a bright place, the light is turned off. In darkness such as time and night, pictures cannot be seen. Therefore, an object of the present invention is to provide a cosmetic material that allows a design to be seen in darkness and also allows a novel design expression.

[0004]

Means for Solving the Problems In order to solve the above problems,
The decorative material of the present invention has a configuration in which a luminous pattern layer having luminous properties is formed on a substrate. As a result, even if it becomes dark, the luminous pattern layer emits light by the energy accumulated during the previous bright period, and the pattern can be seen in the dark. In addition, the decorative material of the present invention has a configuration in which the luminous pattern layer has a light diffusing property with respect to the above configuration. As a result, the phosphorescent picture layer appears matte when it is brighter. Therefore,
The luminous pattern layer can express a design that emits light when it is dark, and a matte design when it is bright. Therefore, it is possible to make a novel decorative plate that can express different designs depending on the brightness.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the decorative material of the present invention will be described with reference to the drawings. 1 and 2
It is sectional drawing of the various forms of the cosmetics of this invention.

[Summary] First, FIG. 1 is a sectional view showing some of the embodiments of the decorative material of the present invention.
Shows a decorative material D in which a phosphorescent picture layer 1 is formed in a pattern on a base material B. The luminous pattern layer 1 has at least luminous properties and may also have light diffusing properties. FIG. 1 (B) shows a base coat layer 2 on the entire surface of one side of the base material B to indicate the base color and the like.
Is formed, and the decorative material D in which the luminous pattern layer 1 as described above is formed on the base coat layer is shown. FIG.
A decorative material D having a configuration in which a non-luminous pattern layer 3 having no luminous property is formed on a substrate B together with a luminous pattern layer 1 is shown. FIG. 1 (D) shows the structure of FIG.
Further, a decorative material D having a configuration in which a transparent resin layer 4 is formed on the entire surface is shown. In a configuration in which the luminous pattern layer is not exposed as shown in FIG. 1D, the luminous pattern layer is usually not light diffusing. In the decorative material of the present invention, the pattern may be a pattern composed of only the luminous pattern layer, but usually, the non-luminous pattern layer 3 is also used as a pattern that cannot be seen when it is dark but is visible when it is bright. It is preferable in that it further enriches. The non-phosphorescent picture layer 3 may be formed of, for example, a conventionally known ordinary material. In order to make the phosphorescent pattern layer phosphorescent, a phosphorescent pigment may be contained in the layer. Further, in order to make the luminous pattern layer light diffusive, a light diffusing agent such as silica may be contained.
In addition, when the luminous pigment used has a light diffusing property, the addition of the light diffusing agent can be omitted. That is, the phosphorescent pigment layer may be a phosphorescent pigment layer containing only the phosphorescent pigment or at least the phosphorescent pigment and the light diffusing agent in the binder resin. Then, the luminous pattern layer can be viewed as a luminous pattern when dark, allowing a novel design expression. Furthermore, if the light-storing picture layer is made to be light diffusive, the light-storing picture layer will appear as a matte (matte) picture when it is bright, allowing a more novel design expression.

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

[Substrate] The substrate B is not particularly limited. It may be colored or uncolored, either. of course,
The coloring may be a color originally possessed by the base material itself. Further, it may be transparent (transparent coloring or transparent non-coloring) or opaque. However, since the decorative material of the present invention is used by making use of a pattern that can be seen in a dark place, even if the front side (space) of the decorative material becomes dark, at that time (that is, the luminous pattern layer emits light). On the other hand, if the back side is to be used in a place where the back side is bright, you can use an opaque material that blocks light from the back side (of course, the transparency as a cosmetic material) Is required). In this case, even when the base material is transparent, when the base coat layer 2 is formed between the base material B and the luminous pattern layer 1 as shown in FIG. 1B, the base coat layer may be opaque.

Materials for the base material include, for example, metal materials such as iron, aluminum and copper; inorganic materials such as pottery, porcelain, glass and enamel; and veneers and plywood made of various tree species such as cedar, cypress and oak;
Wood materials such as particle board, acrylic resins such as polymethyl methacrylate, polyolefin resins such as polypropylene, resin materials such as ABS resin, phenol resin and polyester resin, and fibrous materials such as paper and nonwoven fabric. The form of the base material may be a sheet form in addition to the plate material. Substrate thickness is 10μm depending on application
It is about 1 cm, but may be outside this range. In the case of a metal material, a sheet material such as a mild steel plate, an electroformed iron foil, an aluminum plate, a copper plate or the like, or a material obtained by plating one or more of zinc, tin, lead, aluminum, copper, chromium, nickel, etc. Etc. can be used. Examples of the two or more types of plating include alloy plating of iron and zinc, alloy plating of aluminum and zinc, and the like.

(Base coat layer) The base material may be provided with a base coat layer 2 as needed. The base coat layer is a base treatment layer used for giving a base color and smoothing fine irregularities on the base material surface. The base coat layer may be formed by a conventionally known material and a forming method (a coating method or a printing method). For example, printing methods such as gravure printing, silk screen printing, offset printing, gravure offset printing, roll coating, spray coating,
This is a coating method such as flow coating. The resin used for the base coat layer is not particularly limited, and a resin according to the intended use may be used. For example, if a thermosetting resin such as a polyester resin, an acrylic resin, or an epoxy resin is used, the durability is good. When the base color is given by the base coat layer, the pattern is recognized only by the matte feeling in the light-storing picture layer when it is bright, but when it is difficult to be recognized by the color tone difference from the surroundings, the base coat layer is used. Is preferably the same as the color tone of the phosphorescent pattern layer when it is bright.

(Primer layer) In order to improve the adhesion between the base coat layer and the substrate, a primer layer may be provided between these two layers (see reference numeral 4 in FIG. 2). The primer layer may be formed by a conventionally known material and a forming method (a coating method or a printing method) as in the case of the base coat. The resin used for the base coat layer is not particularly limited, and a resin according to the intended use may be used. For example, if a thermosetting resin such as a polyester resin, an acrylic resin, or an epoxy resin is used, the durability is good.

[Phosphorescent Picture Layer] The phosphorescent picture layer 1 is a layer having at least a luminous property and further having a light diffusing property in accordance with an intended design expression or the like. As a layer containing in the binder resin,
What is necessary is just to form by a well-known printing method etc. The pattern represented by the phosphorescent pattern layer is not particularly limited. The light-storing picture layer may be a single layer or a multi-layer in which a plurality of layers are overlapped, and may be a single color or a multi-color, similarly to a conventionally known ordinary picture layer. In the case of a single layer, it is usually formed in a pattern to represent a picture. In the case of a multilayer, at least one layer is usually formed in a pattern to represent a picture. In the case of multiple layers, the layers usually partially overlap each other. In multicolor, a combination of layers with different emission colors, a combination of layers with different tones when bright,
Alternatively, a combination of both of them is used. In multicolor,
The layers of different colors do not overlap each other and are separated and independent as a single layer, or a multilayer that overlaps. Further, the entire surface of the base material may be covered with the luminous pattern layer. However, in this case, since the single light-storing picture layer is an all-solid layer, a negative pattern of the non-storing picture layer can be seen when it is dark, such as by providing a non-storing picture layer that covers a part of the light-storing picture layer. It is good to do.

A pigment or the like may be used. In this system, the traditional ZnS:
The longer the stimulating light is compared to Cu, the longer the stimulating time
The higher the afterglow luminance is obtained, the higher the brightness.

The light diffusing agent is a matting agent (matting agent) that roughens the surface of the luminous pattern layer to diffuse light to form a matte surface (matte surface). Examples thereof include silica, alumina, and calcium carbonate. Particles such as precipitated barium sulfate may be used. These particles have a particle size of, for example, about 0.5 to 30 μm.

The luminous pattern layer is printed with an ink (or coating liquid) obtained by appropriately adding a luminous pigment and, if necessary, various additives such as a light diffusing agent to a vehicle using a resin as a binder resin. (Or coating). As the resin of the ink binder, a thermoplastic resin such as an acrylic resin or a curable resin such as a polyurethane resin may be used. However, in terms of durability and the like, a polyester resin, an aminoalkyd resin, and a thermosetting acrylic resin are used. And the like are preferred. The luminous picture layer is conventionally known as a chromatic or achromatic colorant in order to adjust a bright color tone (for example, white or pale yellow) by the luminous pigment itself or to obtain a desired color tone. May be used in combination.

The content of the luminous pigment in the luminous pattern layer may be increased or decreased depending on the desired effect. For example, the luminous pigment is 5 to 20 parts by weight per 100 parts by weight of the binder resin.
It is good to use in the range of 0 parts by weight. If the amount of the luminous pigment is less than this range, the effect cannot be sufficiently obtained. Conversely, if the amount exceeds this range, ink suitability and printability (or coating liquid suitability, coating suitability) are reduced, and cost is high. Become. On the other hand, when the amount is too large, the mode in which the color tone and the pattern of the base material under the phosphorescent picture layer can be seen through cannot be seen through.
When a light diffusing agent is also contained in the luminous pattern layer, the content thereof may be increased or decreased according to the degree of the matting effect and the intended matting effect of the luminous pigment to be contained. For example, the light diffusing agent is used in the range of 0.1 to 5 parts by weight per 100 parts by weight of the binder resin.

As a method of forming such a luminous pattern layer by printing, known printing means such as gravure printing, silk screen printing, offset printing, gravure offset printing, or hand drawing with a brush, roll coat, spray coat, etc. May be used. In the case of a solid layer on the entire surface, known coating means such as roll coating, spray coating, flow coating and the like may be used. Above all, silk screen printing is preferable in that the phosphorescent pattern layer can be formed thick, and thus the luminous luminance can be increased while retaining a sufficient phosphorescent pigment.
In addition, silk screen printing makes it easy to form a luminous pattern layer in a spot-like manner. Moreover, compared to gravure printing or gravure offset printing, etc., plate production is easy and suitable for multi-kind small-quantity printing, so the non-phosphorescent pattern layer described later is printed by gravure printing or gravure offset printing, etc.
There is an advantage that a decorative material in which only the phosphorescent pattern layer is replaced with various patterns can be easily manufactured, and a low-cost decorative material can be obtained.
The thickness of the luminous pattern layer is not particularly limited, but is appropriately set depending on the effect. For example, it is about 3 to 100 μm. Further, the thickness varies depending on the content of the luminous pigment even when the same effect is obtained.

[Non-luminous picture layer] The non-luminous picture layer is a pattern layer having no luminous property. The non-phosphorescent picture layer expresses a picture that can be seen when bright. In the decorative material of the present invention, as illustrated in FIG. 1 (C), the non-luminous pattern layer 3 may be used in combination. If a pattern with a non-phosphorescent pattern layer is used together with a pattern with a phosphorescent pattern layer, more complex and rich design expression can be achieved. The non-phosphorescent picture layer may be transparent or opaque. Further, the non-phosphorescent picture layer may be matt or glossy. At least a part of the non-phosphorescent picture layer may overlap with the phosphorescent picture layer. However, usually, since the luminous pattern layer becomes opaque due to the luminous pigment or the like contained in the luminous pattern layer, when overlapping, the non-luminous pattern layer is formed so as to overlap the luminous pattern layer. Of course, a non-phosphorescent picture layer may be formed below the opaque phosphorescent picture layer if it does not hinder the overall picture expression.
Alternatively, it may be formed as a layer above and below the phosphorescent picture layer. In the case where the non-luminous pattern layer is formed on the non-luminous pattern layer for the purpose of concealing at least a part of the luminous pattern layer, the non-luminous pattern layer is opaque. A non-phosphorescent picture layer is superimposed on at least a part of the phosphorescent picture layer, but when utilizing the light emission from the lower phosphorescent picture layer, the non-phosphorescent picture layer is at least as transparent as the light emission from the phosphorescent picture layer can be seen. And In order to make the non-phosphorescent picture layer transparent, in addition to making the layer itself a transparent layer, the layer may be scattered (for example, in a halftone dot shape) to make it seem transparent. When at least a part of the phosphorescent picture layer is concealed by the non-phosphorescent picture layer, the reverse pattern (negative pattern) of the non-phosphorescent picture layer can be used as the light emitting pattern of the phosphorescent picture layer. The non-luminous picture layer is also used as a layer representing a pattern by the luminous picture layer which is visible when dark.

The method for forming the non-phosphorescent picture layer is not particularly limited, and printing means such as gravure printing, silk screen printing, offset printing, gravure offset printing, or known forming means such as hand drawing with a brush, roller, spray, or the like. But it is good. The binder resin constituting the vehicle of the ink or the coating liquid used for forming the non-phosphorescent picture layer may be a thermoplastic resin such as an acrylic resin, or a curable resin such as a polyurethane resin. Thermosetting resins such as a series resin, an aminoalkyd resin, and a thermosetting acrylic resin are preferable. In addition, conventionally known coloring agents such as pigments and dyes, and other various additives such as extender pigments and light diffusing agents are appropriately added to the vehicle as needed.

[Pattern of Luminescent Picture Layer and Pattern of Non-Luminous Picture Layer] As described above, the decorative material of the present invention may be composed of only the pattern formed by the luminous pattern layer. May be used together. It is preferable to use a non-luminous pattern layer in combination with the luminous pattern layer in that a more complex and highly designed decorative material can be obtained depending on the patterns of both layers. Luminescent picture layer pattern,
There is no particular limitation on the pattern of the non-phosphorescent picture layer alone and in the case of combining the non-luminous picture layer, and the pattern may be a pattern according to the application or design. Further, the pattern of the light-storing picture layer and the pattern of the non-storing picture layer may or may not be coordinated. Further, a pattern of the light-storing pattern layer and a pattern of the non-storing pattern layer may be combined to form a certain pattern, or unrelated patterns may be combined as both patterns. For example, a large pattern is given by the pattern of the phosphorescent picture layer, and a small pattern is given by a non-phosphorescent picture layer which is placed on the phosphorescent picture layer when overlapping. At this time,
Further, the base coat layer described above may be used to give the entire background color. As a specific example, for example, the non-phosphorescent picture layer is a cloud pattern or a grain pattern, and the pattern of the phosphorescent picture layer is a flower, a bird,
The pattern of the luminous pattern layer, such as Fengetsu and polka dots, is made larger than the pattern of the non-luminous pattern layer. Then, the non-phosphorescent pattern layer expressing a small pattern, at least in a portion overlapping the phosphorescent pattern layer, the non-luminous pattern layer is scattered independently and independently, so that the phosphorescent pattern layer is exposed from between. And so on.

In the case where the luminous pattern layer has a light diffusing property,
In contrast to the matte pattern (matte pattern) of the phosphorescent picture layer, the non-phosphorescent picture layer may be a matte pattern, a gross pattern (a glossy pattern) or any type. Combine according to the application. For example, the base coat layer may be a solid pattern on the entire surface, but it is preferable that the base coat layer is glossy in order to make the mat pattern formed by the luminous picture layer stand out, and that a gloss mat pattern is used as a whole. However, it is also possible that the base coat layer is matte as in the case of the phosphorescent picture layer, and the entire surface is based on a matte tone. By making a difference between the bright colors of these two layers, the pattern of the phosphorescent pattern layer is recognized. In this case, when a non-luminous pattern layer is provided, there is also a design expression that makes it glossy.

[Transparent Resin Layer] A transparent resin layer 4 is formed on the luminous pattern layer or the non-luminous pattern layer as a protective layer or the like for protecting the luminous pattern layer and especially the non-luminous pattern layer. Is also good. Of course, the transparent resin layer is a transparent clear layer.
The transparency may be colored and transparent. Usually, the transparent resin layer is formed on the entire surface. That is, the transparent resin layer is also called a top coat layer or an overprint layer. When a transparent resin layer is formed on the luminous pattern layer, the luminous pattern layer is not exposed to the surface. For this reason, the phosphorescent pattern layer does not have to be light diffusing. Also,
In addition to the protective function, the transparent resin layer is also used to provide functions such as design feeling such as painting feeling, high gloss feeling, matte feeling etc.
It is provided as appropriate as needed.

The transparent resin layer is not particularly limited, and may be provided by a conventionally known material and a forming method according to required physical properties, applications, and the like. The transparent resin layer is formed by applying or printing a resin liquid. As the resin used for the transparent resin layer, a thermoplastic resin such as an acrylic resin or a curable resin such as a polyurethane resin may be used. However, in terms of surface physical properties and durability, a polyester resin, an amino alkyd resin, and a thermosetting resin are used. Thermosetting resins such as hydrophilic acrylic resins and silicone resins are preferred. The resin liquid (ink or coating liquid) may be formed as a solvent-free or solvent-diluted solution by a known forming method such as a printing method such as gravure offset printing and a coating method such as roll coating and curtain flow coating. The thickness may be appropriately set according to the application, required physical properties, and the like.
It is about μm. Various additives such as a filler, an extender, a coloring agent, a lubricant, a lubricant, an ultraviolet absorber, and a light stabilizer are appropriately added to the resin liquid as needed.

[Use of Cosmetic Material] The use of the cosmetic material is not particularly limited. For example, building interior materials such as walls, ceilings, floors, etc., exterior materials such as entrance doors, surface materials for home appliances such as refrigerators, air conditioners and heaters, surface materials for housing equipment such as unit baths and kitchens, and interior materials for elevators , Partition surface materials, vehicle interior materials such as automobiles, trains, aircraft, and ships. In particular, since the decorative material of the present invention has a pattern that can be seen even in the dark, it is used, for example, as a decorative steel plate on the surface of a refrigerator, and when the light is off at night, as a mark indicating the location of the refrigerator, using a phosphorescent pattern layer. There is. It is also suitable for applications such as emergency exits and evacuation routes, even in the event of a power outage. Further, if the light-storing picture layer is made to have a light diffusing property, when it is bright, it is possible to express a sense of design by a pattern of matte feeling.

[0025]

EXAMPLES The present invention will be described more specifically with reference to the following examples.

A decorative material D having the structure shown in FIG. 2 was manufactured as follows. As the base material B, a plated steel plate (0.45 mm thick) in which an alloy plate of iron and zinc was applied to an iron plate was prepared. Then, a primer coating composed of a thermosetting polyester resin was roll-coated on the entire surface of one side, and then cured by heating to form a primer layer 5. Next, on the primer layer, a gray colored ink composed of a thermosetting polyester resin, after gravure offset printing,
Heat-curing was performed to form a gray and glossy base coat layer 2 (which is also a solid non-luminous pattern layer on the entire surface).

Next, on the base coat layer 2, a thermosetting polyester resin is used as a vehicle binder resin, and a yellow-green emitting ZnS: Cu is used as a luminous pigment for 100 parts by weight of the resin. An ink containing 10 parts by weight of powder was prepared, and the ink was silk-screen printed and then heat-cured to form a phosphorescent pattern layer 1 having a pattern representing a one-point bird pattern on a part of the surface. .

Next, the vehicle binder resin is a thermosetting polyester resin, which is subjected to gravure offset printing using an ink obtained by adding a coloring pigment thereto, followed by heat curing to obtain a luminous pattern layer. The transparent non-luminous pattern layer 3 having a pink overall color tone having a cloud pattern smaller than the pattern pattern (a pattern like a cleavage plane of granite) was formed. In addition,
The non-phosphorescent picture layer 3 was formed as a layer that partially overlaps the phosphorescent picture layer 1. Further, after a curtain flow coat of a colorless and transparent coating liquid composed of a thermosetting polyester resin on the entire surface, the composition is heat-cured to form a transparent resin layer as a protective layer. Material D was obtained. Incidentally, in the decorative material D of the present invention shown in FIG. 2, the primer layer 5 and the base coat layer 2 are formed on the entire surface of the base material B, and the pattern-like luminous pattern layer 1 is further formed on the base coat layer 2. In this configuration, a transparent non-luminous pattern layer 3 is formed so as to cover a part of the luminous pattern layer 1, and a transparent resin layer 4 as a protective layer is further formed on the entire surface.

In the obtained decorative material, the pattern of the non-luminous pattern layer and the colored base coat layer can be seen when bright, and the pattern of the luminous pattern layer which shines in the dark (by light energy absorbed when bright). It is a novel design expression that can only be seen in the past, which can not be expressed conventionally.

[0030]

According to the decorative material of the present invention, the light-storing picture layer having the light-storing property makes it possible to realize a design expression that can be seen as a picture illuminated when dark. As a result, a novel design expression that has never existed before becomes possible. For example, a decorative steel plate for a refrigerator can be used as a design or the like indicating the location of the refrigerator when the lamp is turned off. Furthermore, if the luminous pattern layer is made to be light diffusing, it can be seen as a matte (matte surface) pattern when bright.
Design expression becomes possible. As a result, a more novel design expression becomes possible.
