Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer film having a wood grain pattern and a wood grain decorative material, and more particularly to a measure for designing a house interior material.

[0002]

2. Description of the Related Art Conventionally, as interior materials for homes, design products having a wood texture have been preferred. For example, doors, doors of system kitchens, furniture, etc. are cut from natural wood into a predetermined shape or sliced into thin pieces. The veneer is made as a material, or is imitated as if it is made of natural wood, using materials other than these.

These manufacturing methods are roughly classified as follows.

As shown in FIG. 5, a transparent coating material such as polyurethane is applied to the surface of a base material a made of a plate made of natural wood to form a resin layer b. The uneven shape d is formed on the surface of the resin layer b corresponding to the uneven shape c of the conduit that is inherently provided.

As shown in FIG. 6, a medium density fiberboard (MDF) not made of natural wood, a particle board which is a processed product of natural wood, or the like is used as a base material a, and a film having a wood grain pattern e is used. A printed layer f of paper or the like is attached to the base material a via an adhesive layer h, and a transparent resin layer i is further laminated thereon, and then the irregular shape j of the conduit is embossed on the transparent resin layer i. To do.

As shown in FIG. 7, a transfer film p is prepared in which a release layer m, a print layer n having a grain pattern e, and a hot melt adhesive layer o are sequentially laminated on one surface of a support k made of a film, The hot-melt adhesive layer o of the transfer film p is formed on the medium density fiberboard (MD
F) or a particle board made of particle board or the like is pressed against the surface of the base material a, and in this state, the support k is separated from the other layers with the release layer m as a boundary, whereby a hot melt adhesive is applied to the surface of the base material a. Layer o and printed layer n are laminated.

[0007]

However, in the wood grain tone decorative material obtained by the above-mentioned manufacturing method, although there is no problem in terms of wood tone because genuine natural wood is used as the base material a, it is not Since coating is performed on the surface of the material a, there is a problem that it takes time and labor for coating to reduce workability, and paint mist scatters in the workplace during coating to deteriorate the working environment.

In the woodgrain decorative material obtained by the above-mentioned manufacturing method, the woodgrain pattern e can be provided by the woodgrain pattern e of the print layer f and the uneven shape j of the transparent resin layer i.
After all, the wood grain pattern e and the uneven shape j are imitations, and since the outermost layer is a resin, the texture is far from natural wood and cannot match that of natural wood. Unevenness, graininess, shiny feeling and fibrous feeling cannot be expressed. Further, the transparent resin layer i is soft and has a low surface hardness and scratch resistance because the embossing is required to obtain the uneven shape j on the surface.

Also in the woodgrain decorative material obtained by the above-mentioned manufacturing method, the grain pattern e of the transferred print layer n is imitated in the same manner as in the above case, and the natural grain of wood which is genuine in the grain feeling is There is a big gap.

The present invention has been made in view of the above points, and an object thereof is to create an atmosphere comparable to a wood grain decorative material made of genuine natural wood that is a processed product. The purpose is to efficiently obtain woodgrain decorative materials.

[0011]

In order to achieve the above object, the present invention allows a conduit of a base material made of genuine natural wood to be seen through a grain pattern of a printed layer, and further the hardness of an outermost layer. It is characterized by being raised.

That is, the first and second solving means of the present invention relate to a transfer film having a wood grain pattern, and the first solving means is a release layer, a resin hard film on one surface of a support made of a film. The invention is characterized in that a coat layer, a see-through print layer having a grain pattern and a hot melt adhesive layer are sequentially laminated.

The above-mentioned support is a base film used as a support for ordinary transfer films, and is, for example, a thermoplastic resin film such as polyvinyl chloride or polyester.

The peeling layer is for facilitating peeling of the base film (support) from the other remaining layers as the transfer layer at the time of transfer by a vacuum press or the like, for example, an acrylic resin. Resins such as hydrocarbon resins and olefin chloride resins, and waxes such as paraffin wax and synthetic wax are used.

The above resin hard coat layer is generally formed by a hard coat treatment agent which is spray-coated for imparting scratch resistance as a final finish in high-quality furniture made of natural wood. Resin, acrylic resin, urethane resin, mixed type of these, silicone resin, etc. are used.

The above print layer is for applying makeup to an object to be transferred, and comprises a vinyl chloride / vinyl acetate copolymer,
A thermoplastic resin such as polyamide, polyacryl, polyurethane, polyvinyl acetate, polyester, polyvinyl urethane, or chlorinated rubber is used as a binder, and a material containing a dye or pigment of an appropriate color as a coloring material is used.

The print layer has a wood grain pattern, and is transparent so that the transfer target can be seen through the print layer after transfer.

The hot melt adhesive layer is for adhering each layer including the print layer to the transfer object under the vacuum pressing condition at the time of transfer, and it depends on the material of the transfer object, but the acrylic resin or the styrene resin. ,polyamide,
Chlorinated polyolefin, chlorinated ethylene vinyl acetate copolymer, cyclized rubber, coumarone indene resin and the like are used. As the processing method, a commonly used printing method such as a gravure printing method or a screen printing method or a roll coater method can be adopted.

Then, as shown in FIG. 3, the hot melt adhesive layer 5 of the transfer film A (see FIG. 1) by the first solution means is pressed against the surface of the base material 7, and in this state, the support 1 is peeled off. By peeling from the other layers at the boundary of 2, a woodgrain decorative material is obtained in which the hot-melt adhesive layer 5, the print layer 4, and the resin hard coat layer 3 are sequentially laminated on the surface of the base material 7. In FIG. 3, the peeling layer 2 remains in the outermost layer of this wood grain decorative material. The surface of the obtained woodgrain decorative material (the surface of the peeling layer 2) has an uneven shape 2a corresponding to the uneven shape 9a of the conduit on the surface of the veneer 9.

A wood grain decorative material is obtained in which the melt adhesive layer 5, the print layer 4, the color transparent layer 6 and the resin hard coat layer 3 are sequentially laminated. Also in FIG. 4, the peeling layer 2 remains in the outermost layer of the wood grain decorative material. On the surface of the obtained woodgrain decorative material (the surface of the release layer 2), the uneven shape 2a is formed corresponding to the uneven shape 9a of the conduit on the surface of the veneer 9.

According to the first to fourth means of the present invention having the above-mentioned constitution, the uneven shape of the natural wood conduit on the surface of the base material can be seen through the printed layer, and this can be combined with the grain pattern of the printed layer. The fiber feeling, the shiny feeling, and the texture of the wood are excellent. Further, the resin hard-coded layer constituting the transfer layer eliminates the need for spray painting which is troublesome and which deteriorates the working environment, and improves the surface hardness to improve scratch resistance.
