Description

  The present invention relates to a method capable of easily producing an embossed decorative sheet having a concavo-convex pattern by embossing on the surface, and an embossed decorative sheet obtained as a result. In particular, the present invention relates to an embossed decorative sheet and a method for manufacturing the same, which can quickly respond to small-volume production applications such as presentation, trial production, and single-product production.

2. Description of the Related Art Conventionally, embossed decorative sheets provided with a concavo-convex pattern on the surface by embossing have been used for various applications such as housing members, doors, and fixtures. Various methods and structures for producing such embossed decorative sheets are known. Among them, if a typical production method is exemplified, a pattern printing layer is provided on a colored thermoplastic resin film by gravure printing or the like to form a printing film. In addition, a transparent thermoplastic resin film is formed on the surface of the printed film on the pattern printing layer side, and the two films are heated and pressed together to be laminated and bonded, and at the same time, an uneven pattern is formed on the surface of the transparent thermoplastic resin film by embossing. There is a manufacturing method called “doubling embossing method” (for example, Patent Document 1). Alternatively, there is a method of providing a concavo-convex pattern by embossing at the same time that a transparent thermoplastic resin is melt-extruded and coated on the pattern print layer surface of the print film.
If the structure of the embossed decorative sheet obtained by these methods is exemplified, at least a patterned printing layer and a transparent thermoplastic resin film are sequentially laminated on the colored thermoplastic resin film, and further on the surface of the transparent thermoplastic resin film. For example, a concavo-convex pattern is formed. In addition, the embossed decorative sheet surface is further provided with other layers as appropriate, such as further forming a surface resin layer for gloss adjustment by coating or the like, if necessary.

  On the other hand, the ink jet printing method has recently become widespread for printers, and since the ink jet printing method is a plateless printing method, the plate making time can be greatly shortened, and attention is paid to the point that it corresponds to a small lot. Then, adoption of the inkjet printing method is proposed also for the conventional gravure printing uses, such as decorative paper (for example, patent document 2).

Japanese Examined Patent Publication No. 58-14312 Japanese Patent No. 3475912

  By the way, in the case of an embossed decorative sheet, embossing is generally performed continuously on a continuous strip-like transparent thermoplastic resin film using a cylindrical embossing roll in that it is excellent in mass productivity. However, embossing using an embossing roll, which requires a large production, is not suitable when presenting a new design sample, making a prototype, or manufacturing a small-scale product such as an application. Therefore, in the case of such a small-scale production, for example, it is manufactured as follows. In other words, a continuous belt-shaped (web) colored thermoplastic resin film is cut into, for example, a sheet of about 50 cm square, and a multi-color printing is performed with a small sheet-type flat gravure rotary printing press using a solvent ink on the sheet. A printing sheet is prepared, and a transparent thermoplastic film and a flat silicone resin embossing plate having an embossing shape similar to the embossing roll are laminated on the printing sheet and heated at high frequency with a flat pressure press. By cooling after pressurization, an embossed pattern was embossed on the surface of the transparent thermoplastic resin film and both films were laminated and adhered. Further, if necessary, the surface gloss is adjusted by providing a surface resin layer on the surface by spray coating or the like.

  However, embossing using a flat silicone resin embossing plate and a flat pressure press as described above is suitable for small-volume production compared to the case of using an embossing roll. Prompt response was difficult, and it was not a method that could be said to be productive. In particular, as the ink-jet printing method that allows easy single-product production and enables on-demand type as described above has become widespread, the low productivity of embossing has become relatively conspicuous. In addition, recently as a new design sample, an embossed decorative sheet of a large size (for example, a size of about 1 m in width x 2 m in height) is required as much as one door, and an embossed plate made of silicone resin and a flat pressure press. Embossing using a machine was unsuitable.

  That is, the problem of the present invention is that the embossed decorative sheet can be quickly and efficiently dealt with in small-scale production applications such as presentation, trial production, and one-product production, and also can be accommodated in large sizes such as one door. It is to be.

Therefore, in the embossed decorative sheet manufacturing method of the present invention, pre Me, the uneven pattern embossing using an embossing roll provided on the surface of the front side of the transparent thermoplastic resin film, at least a pressure-sensitive adhesive layer on the other rear surface An embossed adhesive film is prepared, and the embossed adhesive film has an easy-adhesion layer made of a two-component curable urethane resin on both sides, and contains a thermosetting resin binder and nitrified cotton on the easy-adhesion layer. Embossing which is adhesively laminated with the pressure-sensitive adhesive layer on the surface of the printed layer produced by providing a patterned printing layer by an inkjet printing method on a base film made of a thermoplastic resin having an ink receiving layer. It was set as the manufacturing method of the decorative sheet .
Desirably, both the transparent thermoplastic resin film and the base film are made of an olefin resin.
Preferably, a film in which a recoatable surface resin layer is further provided on the surface of the transparent thermoplastic resin film is used as the embossed adhesive film.

Further, in the method for producing an embossed decorative sheet, a pattern printing layer is provided on the base film made of the thermoplastic resin by an inkjet printing method, and then cut into a sheet to produce a sheet-like printing film. The leaf-like printing film is bonded and laminated with the pressure-sensitive adhesive layer of the embossed pressure-sensitive adhesive film on the surface on the pattern printing layer side .

By adopting the manufacturing method as described above, since the inkjet printing method is adopted for printing the pattern printing layer, it is not necessary to make a printing plate, so that even a small production such as one-piece production can be handled quickly and efficiently. Moreover, the embossing of the concavo-convex pattern is prepared and prepared in advance as an embossed pressure-sensitive adhesive film using an embossing roll, and the embossed pressure-sensitive adhesive film can be easily bonded with the printing film and the pressure-sensitive adhesive layer. obtained that effect adoption of, even embossed decorative sheet structure in which a concave and convex pattern by embossing, is not impaired. Furthermore, since the embossing of the embossing adhesive film prepared in advance uses an embossing roll for the embossing plate, a large size is easy and productivity is good.
Therefore, the embossed decorative sheet as a whole can be quickly and efficiently handled in small-volume production applications such as for presentations, trial productions, and one-piece production, and can be easily accommodated in large sizes such as one door.

  According to the present invention, it is possible to quickly and efficiently cope with small-volume production applications such as presentation, trial production, and one-product production, and can easily cope with a large size such as one door.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

First, FIG. 1 is a sectional view showing one embodiment of an embossed decorative sheet manufactured Ri by the present invention, another 1 embodiment of an embossed decorative sheet manufactured Ri by the Figure 2 present invention [Figure 2 (C)], and an embossed adhesive film [FIG. 2 (A)] and a printed film [FIG. 2 (B)] used therefor, are sectional views conceptually illustrating the production method according to the present invention.
In these drawings, the meaning of the symbols is 1 for a transparent thermoplastic resin film, 2 for a concavo-convex pattern, 3 for an adhesive layer, 4 for a surface resin layer, 5 for a release film, 6 for a substrate film, and 7 for a pattern. The printed layer, 10 is an embossed adhesive film, 20 is a printed film, and 30 is an embossed decorative sheet. In each figure, the upper side of the drawing is usually the observer side, and the upper surface of the drawing is called the front surface, and the opposite surface is called the back surface.

[Embossed adhesive film]
The embossed adhesive film 10 is a film that is prepared in advance prior to the production of the printed film so that the embossed adhesive film can be completed immediately after the printed film is produced. The embossed adhesive film 10 is provided with a concavo-convex pattern 2 on the front surface of the transparent thermoplastic resin film 1 by embossing, which is also embossed using an embossing roll as an embossed plate, and the transparent thermoplastic resin film. This is a transparent film provided with at least an adhesive layer 3 on the back side. The embossed adhesive film is made transparent so that the pattern print layer can be seen through, and may be colored and transparent. However, from the viewpoint of versatility that can be commonly used for different designs, it is preferable that the coloring is expressed on the pattern print layer side as non-colored transparent. The transparency may be translucent.
In addition, the embossed adhesive film is usually in the form of a continuous strip film, at least at the time of its manufacture, in that it can be continuously embossed by an embossing roll, but basically it is a continuous strip film when laminated with a printed film. However, either a sheet-like film may be used.

  In addition, if the embossed adhesive film is prepared in advance as a film that is commonly used for rough textured designs, such as for grain, stone, and grain, the embossed adhesive film can be quickly applied to a wider design. It is preferable at the point which can respond. Of course, the same grain may be subdivided into a grain pattern, a grain pattern, or the like.

In addition, on the surface of the front surface of the transparent thermoplastic resin film on which the concavo-convex pattern 2 is formed, if a surface property change such as surface gloss adjustment or surface property improvement is necessary, a transparent surface resin layer can be formed by coating or the like. 4 may be provided.
Preferably, the back surface of the pressure-sensitive adhesive layer 3 is further provided with a release film 5 that protects the pressure-sensitive adhesive layer until use and peels off when used.
As the formation method and material of each layer and the uneven pattern constituting such an embossed adhesive film, a conventionally known method or material may be appropriately employed depending on the application as an embossed decorative sheet for building materials or various adhesive films. There is no particular limitation.

The transparent thermoplastic resin film 1 only needs to have transparency more than the pattern printing layer can be seen through, and thus may be colored transparent or translucent. Moreover, as a resin material of a transparent thermoplastic resin film, what is necessary is just an embossing suitability which can form an uneven | corrugated pattern by the embossing using an embossing roll. As such a resin material, for example, an olefin resin, polyester Examples thereof include resins, acrylic resins, polycarbonate resins, styrene resins, and vinyl chloride resins. Especially, an olefin resin is one of the preferable resins in that it is environmentally friendly.
In addition, the thickness of a transparent thermoplastic resin film should just be a thickness according to a use, and there is no restriction | limiting in particular, For example, it is about 20 micrometers-500 micrometers. Moreover, well-known additives, such as a ultraviolet absorber, a coloring agent, a stabilizer, are suitably added in a transparent thermoplastic resin film as needed.
Moreover, as long as the uneven | corrugated pattern can utilize an embossing roll, you may use the thing for this machine at the time of embossing film preparation with respect to the case where a printing film is manufactured with a large-sized gravure rotary printing machine. Then, the embossing roll can be used in common with this machine.

  The concavo-convex pattern 2 is not particularly limited as long as it corresponds to the application. For example, a wood grain conduit pattern, a wood grain annual ring pattern, a cloth pattern, a grain pattern, a joint pattern, a leather pattern, a hairline pattern, a spin pattern, a geometric pattern, a line-shaped groove, a character, a symbol, and a figure.

By using the pressure-sensitive adhesive layer 3 for adhesive lamination with a printing film, the adhesive lamination can be performed at room temperature. It is not impossible to carry out the adhesion lamination with a heat roller by providing a heat-fusion adhesive layer instead of the pressure-sensitive adhesive layer. However, the use of the pressure-sensitive adhesive layer eliminates the need for a heating means, and at the time of bonding. The heat of the embossed film and printing film can be prevented from being heated.
The pressure-sensitive adhesive layer 3 is not particularly limited as long as it is transparent to the extent that the pattern print layer can be seen through, and may be formed by appropriately adopting a conventionally known pressure-sensitive adhesive and a known formation method. For example, as an adhesive, an acrylic adhesive, a rubber adhesive, etc. are mentioned. Moreover, although formation of an adhesive layer can be formed with various coating methods, in the structure which protects the adhesive layer 3 surface with the peeling film 5, it is a transfer method, for example, once by application etc. on the peeling surface of a peeling film. The formed pressure-sensitive adhesive layer may be formed, for example, by laminating the release film on the back side of the transparent thermoplastic resin film.

As the release film 5, a known release film such as a resin film or paper whose surface is made release by a release agent such as silicone or wax or a release resin may be appropriately used. The release film can be either transparent or opaque, but the transparent film can be temporarily placed on the printing film with the embossed adhesive film in the laminated film state without being permanently bonded. Various combinations with concavo-convex patterns can be easily and temporarily evaluated. Therefore, in this respect, the base film of the release film is preferably a transparent resin film, and for example, the transparent thermoplastic resin film can be used.
In addition, lamination | stacking of an adhesive layer and a peeling film is normally performed after forming an uneven | corrugated pattern and a surface resin layer.

The surface resin layer 4 is a transparent resin layer, and is a layer provided to change surface properties such as surface gloss adjustment or improvement of surface properties such as scratch resistance and recoatability (coating suitability). For example, a recoatable surface resin layer (recoat layer) is a preferred example in terms of more versatile applications. Of course, a surface resin layer having two or more surface properties may be used. Such a surface resin layer may be appropriately selected from known ones. For example, the surface resin layer is formed by applying a coating liquid of a resin such as a thermosetting resin such as urethane resin or acrylic resin or an ionizing radiation curable resin. In order to adjust the surface gloss, a matting agent such as silica is added to such a coating solution. The surface resin layer is usually formed on the entire surface by coating or the like after forming the concavo-convex pattern, but may be provided before forming the concavo-convex pattern if it has embossing suitability.
In addition, the recoating property is a known coating method such as spray coating on the surface of the concavo-convex pattern after lamination with the printing film (such as the state of the embossed decorative sheet or after lamination on the adherend) or before lamination. This is because another surface resin layer such as a surface coating film is formed. As such a recoatable surface resin layer, for example, a two-component curable urethane resin or the like is used.
In addition, olefin-based resins are suitable as the resin for transparent thermoplastic resin films, but since adhesion is difficult to be obtained, recoatability with a two-component curable urethane resin or the like as described above is required when coating or the like is applied to the surface. It is preferable to provide a surface resin layer. In addition, when the resin of the transparent thermoplastic resin film is an olefin resin, an ultraviolet absorber is usually added to the film, but this bleed-out can be prevented by the surface resin layer, and the back side can also be prevented by the adhesive layer. Can be secured.
Although the recoatable surface resin layer can be said to be a primer layer, other layers such as such a primer layer may be appropriately provided on a surface or an interlayer requiring adhesion strengthening.

[Printing film]
The printing film 20 is produced by providing the pattern printing layer 7 on the laminated surface side with the embossed adhesive film on the base film 6 made of a thermoplastic resin by an ink jet printing method. If the base film is transparent, the pattern print layer 7 may be formed on the back side opposite to the laminated surface of the embossed adhesive film, but usually the surface on the embossed adhesive film laminated surface side of the base film. Let it be the side. The reason is that a resin film alone as a substrate film is difficult to provide a pattern printing layer that accepts ink-jet ink and has good adhesion, so an ink-receiving layer is usually formed on the printing surface, and this ink-receiving layer contains This is because the filler to be used usually becomes opaque, so that the entire base film becomes opaque. Further, the base film in a general decorative sheet is also opaque because it hides the surface color of the adherend.

  The base film is a film using a resin film because a resin-made embossed decorative sheet is produced, and a thermoplastic resin is used as the resin. The thermoplastic resin is not particularly limited and may be appropriately selected according to the application. Examples thereof include olefin resins, polyester resins, acrylic resins, polycarbonate resins, styrene resins, and vinyl chloride resins. . Especially, an olefin resin is one of the preferable resins in that it is environmentally friendly. Furthermore, it is more preferable to use an olefin resin together with the transparent thermoplastic resin film of the embossed adhesive film. In addition, what is necessary is just to let the thickness of a base film be the thickness according to a use, and there is no restriction | limiting in particular, For example, it is about 20 micrometers-500 micrometers. Moreover, well-known various additives are suitably added in a base film as needed.

  In addition, what is necessary is just to employ | adopt a conventionally well-known thing suitably as a well-known inkjet printing film etc. as an ink receiving layer. For example, if a coating solution in which a filler such as silica or calcium carbonate is dispersed in a resin binder using a thermoplastic resin or a thermosetting resin such as an acrylic resin, a polyester resin, or a urethane resin, is formed. good. By adding the filler, a porous and opaque coating film is usually formed as an ink receiving layer.

  Including the case where an ink receiving layer is provided, the substrate film may be either non-colored or colored, transparent (including translucent) or opaque. However, it is preferable that the embossed decorative sheet is covered with an opaque material in order to conceal the adherend. Further, in a conventional general decorative sheet, the base sheet is usually colored brown or the like when providing a woodgrain pattern print layer, and the base film of the present invention is also colored in this way. You may do it. However, in the present invention, white is preferable in the case of coloring from the viewpoint of versatility in consideration of small-volume production applications. If it is white, it can be used in common with wood grain patterns and stone patterns. Moreover, it is also made white opaque when concealability is required (white transparent is translucent). One specific example of the structure of such a base film is a structure in which a white opaque resin film is laminated with a white opaque resin film. Of course, when the entire base film is opaque, the base film may be transparent as long as the ink receiving layer is opaque and the overall opacity is sufficient.

In addition, the ink-jet ink used in ink-jet printing may be either water-based ink or organic solvent-type ink. However, the organic solvent type is more advantageous in terms of drying properties, but the aqueous solution is more advantageous in terms of the environment.
In addition, when forming a pattern printing layer with an inkjet printing method, a base film may be either a continuous strip film or a sheet-like film. For the printing, a commercially available industrial large-sized ink jet printer may be used. If the print size is small, an ink jet printer for personal computers can be used.
In addition, the base film is loaded into the ink jet printer as a roll of continuous belt-like film, and after printing, the continuous belt-like print film is wound up as a roll, cut into a sheet-like print film on the machine, etc. Also good.

[Lamination of embossed adhesive film and printing film]
In order to laminate both films by adhesive lamination, the films are adhered and laminated by the adhesive layer of the embossed adhesive film. The laminating method is not particularly limited, and it may be laminated by pressing with a laminating roller from one side or pressing with a pair of laminating rollers from both sides with respect to both films laminated with the adhesive layer inside. . At this time, both films supplied to the laminating roller portion may be either a continuous strip film, one is a continuous strip film, the other is a single sheet film, and both are single sheet films.
Note that it is preferable to install a laminating roller in the ink jet printer itself so that ink jet printing and laminating can be continuously performed in-line. Of course, printing and laminating may be performed offline. These may be selected in consideration of available facilities. Of course, laminating may be performed by an apparatus such as a laminator or by manual work.

[Other layers or procedures]
In the present invention, a part of the description has been given above, but various conventionally known layers and procedures may be appropriately added according to the application within the scope of the present invention. For example, a primer layer and a surface coating film. The surface coating film can be formed on the surface of the embossed decorative sheet by a known coating method such as spray coating after the embossed decorative sheet is laminated on another adherend or before the lamination.

[Use]
The use of the embossed decorative sheet according to the present invention is not particularly limited, such as for building materials and other uses, but is particularly suitable for low-volume production such as for presentation, trial production, and one-piece production. For example, doors, partitions and other fittings, walls, floors, ceilings, and other housing parts, kitchen doors, closet doors, and other furniture, furniture, etc. It is a use.

  Hereinafter, the present invention will be described more specifically with reference to examples.

[Example 1]

An embossed adhesive film 10 as shown in the cross-sectional view of FIG. As the transparent thermoplastic resin film 1, a continuous polypropylene transparent film having a thickness of 80 μm was used. After heating the transparent thermoplastic resin film 1 to 120 ° C. on a heating drum, the film temperature just before embossing was 160 ° C. with a heater. The film was cooled after being embossed using an embossing roll, and the concavo-convex pattern 2 expressing the wood grain conduit was continuously embossed on the surface.
Furthermore, the surface resin on which the concavo-convex pattern is formed is easily adhered by corona treatment, and then a two-component curable urethane resin-based surface treatment agent having the following composition is solid-printed on the entire surface by gravure printing to make it low-gloss and recoatable. Layer 4 was provided.

<Surface treatment agent>
Main resin: Acrylic polyol 15 parts by weight Curing agent: HMDI (hexamethylene diisocyanate) 5 parts by weight Matting agent: Silica 4 parts by weight Wax 2 parts by weight Solvent 89 parts by weight

  Next, an acrylic resin-based adhesive is applied to the release surface of the release film 5 made of a transparent polypropylene-based film on the back surface of the transparent thermoplastic resin film on which the concavo-convex pattern and the surface resin layer are formed. The continuous strip-shaped pressure-sensitive adhesive film on which the layer 3 was formed was adhered and laminated on the surface of the pressure-sensitive adhesive layer to prepare a continuous strip-shaped embossed pressure-sensitive adhesive film 10 with the release film 5.

  The embossed concavo-convex pattern includes two types of embossing rolls, a grained grain conduit shape and a grained grain conduit shape, and an embossed adhesive film having a grained concavo-convex pattern; Two types of films of the embossed adhesive film were prepared. These embossed pressure-sensitive adhesive films are intended for common use among wood grain designs with different pattern printing layers, for glazing and board.

(2) Production of printing film:
First, as a base film 6 made of a thermoplastic resin in a continuous belt shape, a continuous belt-shaped polypropylene resin film (thickness 80 μm) colored white and opaque by adding 10% by mass of a colorant (titanium oxide) was prepared. After the corona treatment is applied to the front side and the back side of the resin film, an easy-adhesion layer using a two-component curable urethane resin is formed on the back side, and then a two-component curable urethane resin is formed on the surface. After forming the easy-adhesion layer used, a white opaque ink-receiving layer having the following composition was coated on the entire surface by gravure coating using a diluent (ethyl acetate / methyl isobutyl ketone = mass ratio 1/1). A base film was prepared by processing.

<Ink receiving layer>
Two-part curable urethane-based resin 100 parts by mass Nitrified cotton 20 parts by mass Silica (average particle size 2 μm) 100 parts by mass

Next, on the image processing computer, based on the color separation image data for this machine gravure plate, select the ink color extracted from the color mixture profile data that can reproduce the color tone of each plate, and on the monitor screen After confirming the synthesized image, multicolor printing was performed by an ink jet printing method using the ink color. For printing, after forming a 2 m long pattern printing layer on the ink receiving layer surface of a 1 m wide base film unwound from a roll by inkjet printing, the pattern is cut in the width direction to have a 2 m long pattern. A sheet-like printed film was produced.
Inkjet printing used a large inkjet printer (Roland DG Co., Ltd.), and water-based ink was used as inkjet ink.

(3) Lamination:
Next, the embossed adhesive film is peeled off the release film, and the pressure-sensitive adhesive layer is roll-press laminated at the room temperature on the pattern printed layer surface of the sheet-like printed film, and finally the sheet-like embossed decorative sheet Was made. There are two types of the embossed decorative sheets produced, and the concavo-convex patterns are those of a plate and a grid, and the size of the pattern design is 2 m in length and 1 m in width, respectively.

(4) Production of presentation doors:
