Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative material having a pattern that can be seen or hidden depending on the viewing angle.

[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 any of the conventional decorative materials, the pattern of the pattern layer formed by printing is always the same even when viewed from any angle. Therefore, an object of the present invention is to provide a decorative material having a pattern that can be seen or hidden depending on the viewing angle, and that can also express a novel design.

[0004]

In order to solve the above-mentioned problems, in the decorative material of the present invention, a flat pattern layer and a colorless transparent layer or a raised pattern layer having the same appearance as the surroundings are formed on a substrate. The raised pattern layer is not seen from the front, but the raised pattern layer is seen obliquely by a contour having a step. A flat pattern layer formed by ordinary gravure printing or the like can be viewed from the front or from any angle. However, since the raised picture layer is colorless and transparent or has the same appearance as the surroundings, it cannot be seen from any angle as long as it is flat like the flat picture layer. However, since the raised pattern layer is a layer that is thickened and raised to such an extent that the layer thickness can be visually recognized, when viewed obliquely, the contour having the step forms the pattern shape formed by the contour of the raised pattern layer. Will be able to see the picture.

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 which shows the example of various forms of the decorative material of this invention.

[Outline] First, some of various forms of the decorative material of the present invention are illustrated in the cross-sectional view of FIG. FIG.
(A) shows a decorative material D having a configuration in which a flat pattern layer 1 on a base material B and a raised pattern layer 2 which is colorless and transparent or has the same appearance as the surroundings are formed in a pattern. FIG. 1B is a view similar to FIG.
With respect to the configuration of (A), a base coat layer 3 for representing a base color or the like is formed on one entire surface of a base material B, and a flat pattern layer 1 and a raised pattern layer are formed on the base coat layer 3. 2 shows a decorative material D having a configuration in which No. 2 is formed. Further, FIG.
In contrast to the configuration of (A), after the flat pattern layer 1 is formed on the base material B, a flat transparent resin layer 4 serving as a protective layer for the flat pattern layer is formed on the entire surface. A decorative material D having a configuration in which a raised picture layer 2 is formed on a layer 4 is shown.

[0007] In order to make the raised pattern layer transparent and colorless or to have the same appearance as the surroundings, the raised pattern layer appears to have a continuous appearance inside and outside the stepped outline when viewed from the front. . Such a raised picture layer is usually preferably colorless and transparent because it is easy to form. However, the raised pattern layer may have the same appearance as the surroundings. For example, colored opaque or colored transparent,
If the color tone is the same as the surroundings, the raised pattern layer cannot be distinguished from the surroundings. Also, if the surface texture (matte feeling, glossy feeling) is the same as the surroundings, it cannot be distinguished from the surroundings. That is, the above-mentioned appearance refers to color tone, texture, and the like. Normally, a picture layer functions as a picture layer by changing appearance differences such as color tone difference and texture difference from the surroundings discontinuously inside and outside the contour of the layer. However, the above-mentioned raised picture layer has only a contour element as its picture as a discriminating element from the surroundings. Of course, if it is the same as the surroundings (the same appearance), the color tone and the texture may be included as components for representing the picture, but these are not elements for distinguishing from the surroundings. The embossed pattern layer can have various modes as described above, but the embossed pattern layer which is colorless, transparent and glossy (the periphery is glossy) is easy to form, and is viewed from the front or slightly obliquely. This is a preferred embodiment in that it can be hardly identified.

In this manner, the raised picture layer cannot be identified because there is no discontinuous difference in the appearance such as color tone and texture when viewed from the front in the contour portion. However, when viewed obliquely, the pattern formed by the contour of the raised picture layer portion can be distinguished by the step on the outer peripheral portion of the raised picture layer. As a result, the decorative material of the present invention enables a novel design expression that has been impossible in the past. For example,
Hidden patterns can be added. In addition, when viewed from an extremely close distance (for example, 5 cm), the step is easily seen even from the front, but there is usually no practical problem since the cosmetic material is used on the premise that it is viewed farther away. . Even when viewed from such a short distance, a change in the appearance of the raised picture layer can be obtained when viewed from the front and obliquely.

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. The material of the base material is, for example, a metal material such as iron, aluminum, and copper; an inorganic material such as pottery, porcelain, glass, and enamel;
Wood materials such as veneers and plywood made of various tree species such as cedar, cypress and oak, particle board, acrylic resins such as polymethyl methacrylate, polyolefin resins such as polypropylene, resin materials such as ABS resin, phenol resin and polyester resin Or, 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. The thickness of the base material is 10 μm to 1 cm depending on the application.
To the extent, it 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, or a copper plate, or zinc, tin, lead, aluminum, copper,
One plated with one or more of chromium, nickel and the like 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 3 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 base coat layer can be understood as all solid layers in the flat pattern layer.

(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 5 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.

[Flat pattern layer] The flat pattern layer 1 is a normal pattern layer formed by printing or the like. The thickness of the layer is thinner than the raised pattern layer. The picture layer has such a thickness that the step on the outer periphery of the picture layer cannot be recognized. The flat pattern layer is a pattern layer that can be seen from any angle and gives a base pattern of a decorative material. In addition, as a decorative material, the case where the pattern is only the raised pattern layer without the flat pattern layer can be considered, but the design is poor if there is no pattern that is always visible. The flat pattern layer may be transparent or opaque.
Further, the flat pattern layer may be matte (has fine irregularities and is not smooth) or may be glossy.

Further, at least a part of the flat pattern layer may overlap with the raised pattern layer. However, in the case of overlapping, usually, it is preferable to form the flat pattern layer under the raised color pattern layer which is colorless and transparent. This is because, when a flat pattern layer is formed by printing, a flat surface before the formation of the raised pattern layer is easier to form than a surface having a height difference due to the raised pattern layer. Further, if the flat pattern layer is formed so as to cover the step portion, even if it is viewed from the front, if the viewing position is slightly shifted, the step portion of the raised pattern layer is easily recognized. In addition, if the appearance of the raised pattern layer is not affected by the flat pattern layer formed on the raised pattern layer so as to cover the step portion of the raised pattern layer, a flat pattern layer is formed on the step portion. It may be formed. If the appearance of the raised picture layer is not obstructed, the flat pattern layer may be formed on the raised pattern layer inside the step of the raised pattern layer (inside the outline of the raised pattern layer). .

The method for forming the flat pattern layer is not particularly limited, and printing means such as gravure printing, silk screen printing, offset printing, and gravure offset printing, or known forming means such as hand drawing using a brush, a roller, a 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 flat pattern 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 are appropriately added to the vehicle as needed.

[Mounted Picture Layer] The raised picture layer 2 is a picture layer which is colorless and transparent or has the same appearance as the surroundings and is thickened and raised. In the raised picture layer, when viewed obliquely, the pattern can be distinguished by the step of the contour of the layer, but when viewed from the front (of course, it may be slightly off the front), the step becomes extremely difficult to distinguish. Is a picture layer in which the picture by the layer cannot be determined.
The raised pattern layer is, for example, a thick and transparent resin layer. The raised pattern layer may be a colored layer. This is because it is sufficient if there is a difference in color tone between the raised pattern layer portion and the other portions, that is, outside and inside the contour line portion of the raised pattern layer. Also, the texture such as the matte feeling and the glossy feeling may be any as long as there is no difference along the contour line. Therefore,
In addition to forming the raised picture layer as a transparent resin layer having a thickness, the layer can be appropriately selected according to color transparent, colorless opaque, colored opaque, and the like, and the surrounding color tone. However, a raised pattern layer as a colorless and transparent resin layer having a pattern corresponding to the pattern is one of the preferable embodiments in that it does not require color adjustment or the like to match the surrounding color tone and the like and can be easily formed.

Such a raised pattern layer is formed by adding an ink containing a known additive such as an extender, a coloring agent, and a thixotropic agent to a vehicle containing a resin as a binder, if necessary. It can be formed by printing with. As the binder resin, a thermoplastic resin such as an acrylic resin,
Alternatively, a curable resin such as a polyurethane resin may be used, but a thermosetting resin such as a polyester resin, an aminoalkyd resin, a thermosetting acrylic resin, or a silicone resin is preferable in terms of durability and the like. Since the raised pattern layer is the outermost layer, the raised pattern layer may further include various additives such as a lubricant, a lubricant, an ultraviolet absorber, and a light stabilizer, if necessary. Is also good.

The printing method of such a raised pattern layer is as follows.
There is no particular limitation as long as it can be printed thickly, but silk screen printing or the like is preferred. Silk screen printing is also convenient when forming a raised pattern layer in a spot-like manner, and compared to gravure printing or gravure offset printing, etc., because plate production is easy and suitable for multi-kind small quantity printing,
The flat pattern layer is printed by gravure printing, gravure offset printing, or the like, so that a decorative material in which only the raised pattern layer is replaced with various patterns can be easily manufactured, and there is an advantage that a low-cost decorative material can be obtained. The formation of the raised pattern layer is not limited to the printing method, and may be hand drawing using a brush or the like. The thickness of the raised picture layer is not particularly limited, but is appropriately set depending on the effect. For example, it is about 5 to 20 μm. The embossed pattern layer can also serve as a surface protective layer of the decorative material, together with a transparent resin layer described later.

[Combination of raised pattern layer and flat pattern layer pattern] The pattern of the raised pattern layer and the pattern of the flat pattern layer are not particularly limited, and may be a pattern according to the use and design. . In addition, the pattern of the raised pattern layer and the pattern of the flat pattern layer may or may not be synchronized in position. Further, the pattern of the raised pattern layer and the pattern of the flat pattern layer may be combined to form a certain pattern, or unrelated patterns may be combined as both patterns. For example, the pattern of the raised pattern layer is a large pattern, and the pattern of the flat pattern layer is a small pattern. Also, at this time, the base coat layer described above may further provide a base color of the entire surface. As a specific example, for example, the flat pattern layer is a cloud pattern or a grain pattern, and the pattern of the raised pattern layer is
Flowers, birds, fugetsu, polka dots, etc., and the pattern of the raised pattern layer are made larger than the pattern of the flat pattern layer.

[Transparent Resin Layer] Before forming the raised pattern layer, the transparent resin layer 4 protects the flat pattern layer, and provides a feeling of painting, a high glossiness, a matte feeling, etc. in portions other than the raised pattern layer. For the purpose of imparting a function such as imparting a design feeling of the above, it may be appropriately provided as necessary. Of course, the transparent resin layer is a transparent clear layer. The transparency may be colored and transparent. 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
It is formed by coating or printing with 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 determined according to the application, required physical properties, and the like, and is, for example, about 2 to 30 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. In addition, if the transparent resin layer is provided thinner than the thickness of the raised picture layer so that the height difference of the contour of the raised pattern layer does not obscure the diagonal steps of the contour of the raised pattern layer from being oblique, May be provided. In this case, the transparent resin layer becomes a top coat layer or an overprint layer.

[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.
