Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative material used as an interior / exterior material for construction, a surface material for furniture, a surface material for kitchen, etc., and a method for producing the same.

[0002]

2. Description of the Related Art In recent years, people's sensibilities have become nature-oriented, and there is a tendency for the warmth and ease of natural wood to be demanded.
Conventionally, as a method of obtaining interior and exterior materials for construction, furniture surface materials, kitchen surface materials, etc., sealer coating on wood, etc.,
There is a method of finishing the coating after performing a surface treatment such as polishing. In addition, there is a method of obtaining a decorative plywood by pasting a paper on which wood grain or the like is printed on the surface of a base plate. In addition, there is a method of obtaining a decorative plywood by pasting a vinyl chloride sheet on which wood grain or the like is printed on the surface of a base plate. Further, using a transfer material in which a transfer layer including a release layer, a pattern layer, an adhesive layer and the like is formed on a base sheet, the transfer layer is heated and pressed to bring the transfer layer into close contact with the transfer target, and then the base sheet is peeled off. , There is a method by thermal transfer in which only the transfer layer is transferred to the surface of the transfer target object for decoration.

[0003]

However, each of the above methods has the following drawbacks. That is, the coating method has many steps and requires skill. In addition, since wood is a natural product, it is becoming difficult to obtain high quality wood that has beautiful wood grain in all parts, and the quality of the wood varies widely.

The method of adhering paper is not particularly durable because the paper is particularly vulnerable to humidity and peels off. Also,
The decorated surface is cheesy. In particular, when expressing wood grain, no matter how precisely the wood grain is printed, since it is printed on paper, it is planar and lacks the texture of wood. Furthermore, the unevenness of the wood grain conduit can be expressed only by the difference in gloss between the conduit portion and other portions.

The method of adhering a vinyl chloride sheet has a problem in disaster prevention because it produces a toxic gas at the time of fire. Also, the decorated surface is cheesy. Especially when expressing wood grain, no matter how precisely the wood grain is printed, it is printed on the vinyl chloride sheet,
It is flat and lacks the texture of wood. The unevenness of the conduit is embossed on the PVC sheet, so it is unnatural and unnatural compared to natural wood.

The thermal transfer method does not have heat resistance because it uses a hot melt adhesive. Further, since it does not cut into the unevenness of the transferred material, the adhesion is weak and the pattern may peel off.

Therefore, it is an object of the present invention to provide a decorative material having an expression close to that of natural wood and a method for producing the same, in which the above drawbacks are eliminated.

[0008]

In order to achieve the above object, the decorative material and the method for producing the same of the present invention are configured as follows.

That is, in the decorative material of the present invention, a transfer layer having a pattern layer or the like is formed on a transferred body having an uneven surface, and the transfer layer is made to follow the uneven surface of the transferred body by a temporary solubilizing agent. Configured as described.

In the above invention, the pattern layer may be composed of a transparent colorant. Further, the pattern layer may be composed of a masking colorant. Further, the temporary solubilizer may be composed of a solvent and a resin.

Further, in the method for producing a decorative material of the present invention, a transfer material having a transfer layer having a pattern layer or the like formed on a base sheet is adhered to an object to be transferred having an uneven surface through an adhesive, and then, The substrate sheet of transfer material was peeled off, and then the transfer layer was coated with a temporary solubilizer.

In the above invention, the pattern layer may be composed of a transparent colorant. Further, the pattern layer may be composed of a masking colorant. Further, the temporary solubilizer may be composed of a solvent and a resin.

The present invention will be described in more detail with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of each step of the method for manufacturing a decorative material of the present invention. FIG. 2 is a sectional view showing an embodiment of the transfer material used in the present invention. In the figure,
1 is a base sheet, 2 is a release layer, 3 is a release layer, 4 is a pattern layer, 5 is a transfer material, 6 is an adhesive, 7 is a temporary solubilizing agent, 8
Is a transfer target, and 9 is a decorative material.

In the decorative material 9 of the present invention, a transfer layer having the pattern layer 4 and the like is formed on the transferred body 8 having an uneven surface, and the transfer layer is temporarily solubilized by the solubilizing agent 7 to form the uneven surface of the transferred body 8. Is made to follow. Further, according to the manufacturing method of the decorative material 9 of the present invention, the transfer material 5 in which the transfer layer having the pattern layer 4 and the like is formed on the base sheet 1 is adhered to the transferred material 8 having the uneven surface via the adhesive 6. Then, the base sheet 1 of the transfer material 5 is peeled off, and then the temporary solubilizing agent 7 is applied to the transfer layer.

First, the transfer material 5 is prepared. The transfer material 5 is
In general, the base sheet 1 has a transfer layer including a pattern layer 4 and the like (see FIG. 2).

The base sheet 1 is made of polypropylene resin, polyethylene resin, polyamide resin,
Resin sheet such as polyester resin, acrylic resin, polyvinyl chloride resin, metal foil such as aluminum foil and copper foil, glassine paper, coated paper, cellulosic sheet such as cellophane, or a composite of each of the above ,
What is used as a base sheet of an ordinary transfer material can be used.

When the transfer layer can be easily peeled from the base sheet 1, the transfer layer may be directly provided on the base sheet 1. In order to improve the releasability of the transfer layer from the base sheet 1, the release layer 2 is provided before the transfer layer is provided on the base sheet 1.
May be entirely formed. The release layer 2 is released from the transfer layer together with the base sheet 1 when the body sheet is peeled off after the transfer. Examples of the material of the release layer 2 include melamine resin-based release agents, silicone resin-based release agents, fluororesin-based release agents, cellulose derivative-based release agents, urea resin-based release agents, polyolefin resin-based release agents. Paraffin-based release agents and complex release agents of these may be used. Examples of the method for forming the release layer 2 include a coating method such as a roll coating method and a spray coating method, and a printing method such as a gravure printing method and a screen printing method.

The release layer 3 is provided on the base sheet 1 if necessary.
Alternatively, it is entirely or partially formed on the release layer 2. The peeling layer 3 is a layer that becomes the outermost surface of the transferred body 8 by peeling from the base sheet 1 or the release layer 2 when the base sheet 1 is peeled after transfer. As the material of the release layer 3, acrylic resin, polyester resin, polyvinyl chloride resin,
Cellulose resin, rubber resin, polyurethane resin,
In addition to polyvinyl acetate-based resins, it is preferable to use copolymers such as vinyl chloride-vinyl acetate copolymer-based resins and ethylene-vinyl acetate copolymer-based resins. When abrasion resistance is required after transfer, the release layer 3 may be kneaded with an anti-wear agent such as polyethylene wax. In the release layer 3,
By incorporating an ultraviolet absorber, an antistatic agent, an antifouling agent, etc., each effect can be exhibited. The release layer 3 may be colored or uncolored. As a method for forming the release layer 3, there are a coating method such as a gravure coating method, a roll coating method, and a comma coating method, and a printing method such as a gravure printing method and a screen printing method.

The pattern layer 4 is a layer for forming a pattern on the surface of the transferred body 8. The pattern layer 4 is formed on the base sheet 1 or the release layer 3. The decorative material 9 only needs to have the pattern transferred, and the release layer 3 can be omitted when the surface strength is not a problem. As the material of the pattern layer 4, a resin such as a polyvinyl resin, a polyamide resin, a polyester resin, an acrylic resin, a polyurethane resin, a polyvinyl acetal resin, a polyester urethane resin, a cellulose ester resin, or an alkyd resin is used as a binder. It is advisable to use a colored ink containing a pigment or dye of an appropriate color as a colorant. As a method of forming the pattern layer 4, a normal printing method such as an offset printing method, a gravure printing method, or a screen printing method may be used. Especially for multicolor printing and gradation expression,
Offset printing and gravure printing are suitable. Further, in the case of a single color, a coating method such as a gravure coating method, a roll coating method or a comma coating method can be adopted. The pattern layer 4 can express a grain by including a grain layer and a base layer. The wood grain layer is a layer that expresses the wood grain itself, and may be composed of a single color to several colors. The base layer is entirely monochromatic, and the transferred body 8 is entirely colored. The pattern layer 4 may be made of a transparent colorant. The transparent colorant may be composed of a transparent pigment, a transparent dye, a resin and a solvent. The pattern layer 4 may be composed of a masking colorant. The hiding colorant may be composed of a pigment such as titanium oxide, iron oxide or carbon black, a resin and a solvent.

The transferred material 8 has an uneven surface, and specifically, various natural woods, particle boards, laminated special plywood, core special plywood, single-ply overlay plywood, MDF, etc. may be used. . The veneer overlay plywood is a veneer with a decorative veneer made of natural wood attached to the surface of the base plate. Further, the transferred body 8 is not limited to wood, and may be plastic or metal that has been subjected to texture processing, hairline processing, or the like.

The adhesive 6 is usually applied to the transferred body 8 (see FIGS. 1a and 1b). Depending on the case, it may be applied to the transfer material 5, or may be applied to both the transfer material 5 and the transfer target 8. The adhesive 6 needs to have adhesiveness to both the transferred body 8 and the pattern layer 4 of the transfer material 5. Also, the adhesive 6
Is a solvent type or an oil-emulsified aqueous emulsion type (O / W
Type) is preferred. While solvent-type adhesives have excellent drying properties, they must be environmentally friendly. While the O / W type adhesive is easy to handle, moisture is likely to remain on the transferred body 8, and it is necessary to secure the drying property. Whether to select a solvent type adhesive or an O / W type adhesive may be determined in consideration of equipment and workability. As the adhesive 6, an acrylic resin, an ethylene vinyl acetate copolymer resin, a polyamide resin, an ethylene butyl alcohol resin, a vinyl acetate resin, a urethane resin, or a modified resin thereof can be used. Since the adhesive 6 is usually applied to the transferred body 8 in a liquid state, it easily fits into the material of the transferred body 8 and high adhesive strength can be expected. If a cross-linking type adhesive is selected as the adhesive 6, more excellent durability can be obtained. As a method for applying the adhesive 6, a brush coating method, or a coating method such as a gravure coating method, a roll coating method, a flow coating method, a spray coating method, a comma coating method, a printing method such as a gravure printing method, a screen printing method, or the like. There is. If desired, the adhesive 6 may be dried (see Figure 1c).

Next, the transfer material 5 and the transferred material 8 are overlapped and pressed to bond the pattern layer 4 of the transfer material 5 and the transferred material 8 (see FIG. 1d). If the adhesive 6 is viscous, it can be bonded only by applying pressure. Moreover, it heats as needed.
The purpose of heating is to activate the adhesive 6 layer. A multi-stage press machine or a roll press machine may be used to apply pressure. With a multi-stage press or roll press, heating can be performed simultaneously with pressurization.

Next, the base sheet 1 is removed, and a transfer layer is formed on the surface of the transferred body 8. When the base sheet 1 is peeled off, peeling occurs at the boundary surface between the base sheet 1 and the release layer 3. Only the transfer layer remains on the surface of the transferred body 8, and a pattern can be formed. The transcript thus obtained is
Although the transfer layer is formed so as to cover the transfer target 8, it cannot be said that the transfer layer 8 is adhered sufficiently along the uneven shape of the transfer target 8. Therefore, not only the adhesion is poor, but also the cosmetic material 9
However, it lacks in texture.

Finally, the temporary solubilizing agent 7 is applied from above the transfer layer.
(See FIGS. 1e-g). The temporary solubilizer 7 is
It is necessary that the transfer layer including the pattern layer 4 and the like can be dissolved. Examples of the temporary solubilizer 7 include hydrocarbons such as toluene and xylene, alcohols such as methanol and ethanol, ketones such as MEK and MIBK, esters such as ethyl acetate and butyl acetate, methyl cellulose and butyl cellulose. It is appropriately selected from ethers and the like according to the resin constituting the transfer layer. The temporary solubilizing agent 7 temporarily dissolves the transfer layer including the pattern layer 4 or the like, so that the transfer layer 8 can be adhered to and follow fine irregularities of the transferred body 8. When the transferred material 8 is wood or the like, the degree of unevenness of the surface is large, and therefore the transfer layer cannot be sufficiently adhered to the concave and convex portions due to pressure and heating by transfer, but it is a temporary solubilizing agent. Adhesion can be achieved by applying 7. Further, even if the transfer target 8 has a smooth surface, the surface still has fine irregularities when viewed microscopically, and the degree of adhesion is further increased by the action of the temporary solubilizing agent 7. Can be increased. Alternatively, the temporary solubilizer 7 may be composed of a solvent and a resin. As the resin, acrylic resin,
Urethane resin, polyester resin, etc. can be used. By doing so, the overcoat can be simultaneously formed in the step of using the temporary solubilizing agent 7. As the method for applying the temporary solubilizing agent 7, a brush coating method, a coating method such as a gravure coating method, a roll coating method, a spray coating method, a comma coating method, a flow coating method, a gravure printing method, a screen printing method, etc. There is a printing method. Further, an ultraviolet absorber, an antistatic agent, a dye-proofing agent, an antibacterial agent, an antifungal agent, etc. can be added to the temporary solubilizer 7. If necessary, the temporary solubilizer 7 is dried (see FIG. 1f).

The decorative plywood thus manufactured can be used as an interior / exterior material for construction, a surface material for furniture, a surface material for kitchen, and the like. Further, it can be used after being subjected to post-processing such as urethane coating.
