DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wallpaper with an adhesive, and more particularly to a wallpaper with an adhesive, which can prevent the swelling of the wallpaper when the wallpaper is adhered to the base via the adhesive layer. About technology.

[0002]

2. Description of the Related Art As a wall material (wallpaper) to be applied to a wall surface of a room, a wallpaper with an adhesive is provided. However, when the adhesive-attached wallpaper is adhered to a base such as a wall surface or a top surface via the adhesive layer, a swollen portion occurs in the wallpaper,
This may cause poor adhesion and may easily cause peeling or impair the appearance. Although the cause is not clear, it is considered that air is present between the wallpaper and the ground. As for the wallpaper, as an air (gas) bleeding technique, for example, Japanese Patent Publication No. 55-11455
No. 7, JP-A No. 7-133, discloses that, for a paper provided with an elastic foam on various paper board materials, when an uneven pattern is provided on the foam by pressing of a forming roll, the air in the recess is compressed and the escape port is closed. And, since the uneven pattern is disturbed, a technique of preventing the disorder of the uneven pattern by penetrating the elastic foam from the paper board material and opening countless fine holes to drive out the air at the time of pressing. It has been disclosed. That is, the purpose of the through-hole installation in the art is to prevent disturbance of the pattern when forming a deep uneven pattern in the elastic foam. According to the publication, the through hole improves the workability by, for example, allowing the moisture in the adhesive to rapidly penetrate into the paper board when the wallpaper is attached via the adhesive. is there. That is, the wallpaper in this technology does not have an adhesive, and is later applied and adhered to a wall surface or a paper board material by an adhesive, and is different from a wallpaper with an adhesive having an adhesive layer from the beginning. Further, the wallpaper with the adhesive is used after being pasted once and then peeled off and then re-applied, whereas the wallpaper in the art is intended for complete adhesion. Also, Tokiko Sho 60
JP-A-39544 discloses that after forming a synthetic resin foam layer by foaming a synthetic foamed resin on the upper surface of a base material, the foamed layer is cooled, and the foamed layer and the base material are penetrated by a piercing device. A method for producing a highly foamed sheet with holes is disclosed. This technology is described in Japanese Patent Publication No. 55-114557.
By providing the gas vent holes using the same technology as that of Japanese Patent Application Laid-Open Publication No. H10-110, a highly foamed foam layer with a clear concavo-convex pattern can be obtained. In this publication, it is described that since the heating is performed again for embossing after the formation of the gas vent hole, no trace remains on the foam layer of the finally obtained sheet due to welding. I have. Therefore, the technology disclosed in the publication also discloses that the installation of the gas vent hole is to prevent the pattern from being disturbed when forming a deep uneven pattern, and the gas vent hole is necessary for gas release during foaming. Finally, Japanese Patent Publication No. 60-39544 discloses a decorative sheet having a decorative layer made of a foam on a base material having a peel-up property. There is described a decorative sheet having holes in which the surface of the decorative layer is open but holes are suppressed in the middle of the substrate. According to the publication, when forming a through-hole in the thickness direction as in the publication, the adhesive to be applied to the outer surface of the base material penetrates to the inside of the sheet. It is said that the heel-up property of the sheet is hindered, so that the sheet is not penetrated to the outer surface of the base material, but is stopped halfway and has a peel-up property. In addition, the sheet according to the publication also has the above-mentioned halfway holes in order to increase the expansion ratio of the decorative layer.

SUMMARY OF THE INVENTION An object of the present invention is to provide a technique for solving the above-mentioned drawbacks of the prior art in the construction or use of a wallpaper with an adhesive. Another object of the present invention is to provide a technique capable of preventing the swelling of the wallpaper when the wallpaper with the adhesive is adhered to the base via the adhesive layer. Therefore, even if the present invention relates to the same air bleeding, the problem to be solved is different from the above-mentioned technology in the above-mentioned publication. The above and other objects and novel features of the present invention will become apparent from the description of the present specification and the accompanying drawings.

[0004]

The claims of the present invention are as follows. (Claim 1) In a wallpaper with an adhesive having an adhesive layer capable of adhering to a base on one side of a base material layer and a decorative layer on the other side of the base material layer, A wallpaper with an adhesive, wherein a plurality of through holes are provided in a thickness direction of the wallpaper to prevent swelling of the wallpaper when the wallpaper is adhered via the adhesive layer. (Claim 2) The wallpaper with an adhesive according to claim 1 sequentially passes through the adhesive layer by coating, a base material layer, a synthetic resin paste layer having a pattern, and the pattern. A top coat layer which prevents the transfer of the constituent components from the paste layer and has a release property between the pressure-sensitive adhesive of the pressure-sensitive adhesive layer and the pressure-sensitive adhesive of the pressure-sensitive adhesive layer; Is a roll-type dry-type adhesive that does not require the interposition of an adhesion-preventing member such as a release paper or a plastic film that prevents the adhesive from adhering to the wallpaper surface, and that does not require water wetting. The wallpaper with an adhesive according to claim 1, which is a wallpaper with the adhesive. (Claim 3) In a wallpaper with a pressure-sensitive adhesive having a pressure-sensitive adhesive layer, after laminating the pressure-sensitive adhesive layer, from the outer surface of the pressure-sensitive adhesive layer to the surface of the wallpaper, and sticking the wallpaper to the base via the pressure-sensitive adhesive layer. A method for producing a wallpaper with an adhesive, characterized by forming a plurality of through holes penetrating in the thickness direction thereof in order to prevent the swelling of the wallpaper.

[0005] As described in the above-mentioned publication, a conventional wallpaper is simply configured as a wallpaper provided with a decorative layer on various base materials. When the wallpaper is applied, an adhesive is applied to the surface of the wallpaper or to the base. Although a form of applying and sticking is adopted, wallpaper with an adhesive has come to be proposed due to a demand for shortening the construction time and the like. It is necessary that the wallpaper with the adhesive be one in which the adhesive is applied to one surface of the wallpaper. In such a case, the exposed pressure-sensitive adhesive adheres to the surrounding objects, and the pressure-sensitive adhesive adheres to the wallpaper surface. Therefore, it is necessary to prevent this in some way. For one, a release paper is interposed between the pressure-sensitive adhesive and the surface of the wallpaper, so that when the wallpaper is used, the release paper is peeled off and the wallpaper is attached to the base. Incidentally, a plastic film may be interposed as the adhesion preventing material. On the other hand, without interposing an adhesion preventing material such as release paper as described above, apply an adhesive that exerts adhesive force when wet with water, and when using it, moisten it with water and moisten it and attach it to the wall surface There is also provided a wet type of adhesive-backed wallpaper. The adhesive-backed wallpaper provided with a plurality of through-holes in the thickness direction of the wallpaper of the present invention can be applied to an adhesive-backed wallpaper or a water-wetted-type adhesive-backed wallpaper in which an adhesion preventing material such as release paper is interposed. However, in the case of wallpaper with an adhesive in which an anti-adhesive material such as release paper is interposed, it takes time and effort to peel off the release paper, and once pasted, the wallpaper was pasted even if it was reattached. It is difficult to peel off from the wall surface, and if you try to forcibly peel it, there is a disadvantage that the material of the wall surface will also peel off.
It has the disadvantage of increasing the cost of the wall material. In addition, in the manufacture of the product itself, a transfer method is used in which an adhesive is applied to the release paper side and transferred to the base material side. There is a disadvantage that special equipment is required. On the other hand, the water-wetting type also has a drawback such that it takes time and effort to use it when it is constructed by wet-wetting each time with water and attaching to a wall surface.

Next, the details of the present invention are described as follows. The method does not require the intervention of an adhesion preventing member such as a release paper or a plastic film for preventing the adhesion between the adhesive and the wallpaper surface, which does not have the above-mentioned disadvantages. A description will be given together with a roll-type dry type pressure-sensitive adhesive wallpaper which does not require wetting and an adhesive-type wallpaper.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1A is a sectional view of a wallpaper with an adhesive showing the above embodiment of the present invention, and FIG. 1B is a process explanatory view showing the embodiment of the present invention. (C) is an explanatory view showing the state of swelling of the wallpaper with adhesive, and (D) is a side view of the wallpaper with adhesive showing an example of the present invention.

As shown in FIG. 1 (A), a wallpaper 1 with an adhesive comprises an adhesive layer 2, a base material layer 3, a synthetic resin paste layer 4, a pattern layer 5, and a top coat layer in this order. 6 is provided. Further, the adhesive-attached wallpaper 1 is provided with a plurality of through holes 7 in the thickness direction in order to prevent the wallpaper from swelling. In this embodiment, the synthetic resin paste layer 4
An example is shown in which a wallpaper decoration layer is constituted by the pattern layer 5 and the pattern layer 5. Examples of the base material constituting the base layer 3 include:
Examples include aluminum hydroxide paper, flame retardant paper, and plain paper.
There are various types of pressure-sensitive adhesives constituting the pressure-sensitive adhesive layer 2, but from the above-mentioned purpose, an initial pressure-sensitive adhesive force capable of being applied by a coating method instead of a transfer method and capable of reapplying wallpaper. It is preferable to use an acrylic resin-based pressure-sensitive adhesive because it can be coated by a coating method and has an initial adhesive strength that allows wallpaper to be re-applied. Examples of the acrylic resin-based adhesive include:
An emulsion-type pressure-sensitive adhesive containing an acrylic resin as a main component is used. By coating the pressure-sensitive adhesive, the wallpaper can be used without requiring water wetting (hereinafter referred to as a dry type). The adhesive type mainly comprises a rubber elastomer such as polyacrylate, natural rubber, SBR (styrene / butadiene rubber), polyisobutylene, butyl rubber, NBR (nitrile / butadiene rubber), polyvinylalkyl ether, etc. Is generally used, but for the above purpose, it is preferable to use the above-mentioned pressure-sensitive adhesive containing an acrylic resin as a main component.
The following can be appropriately added to the pressure-sensitive adhesive. Tackifier: Rosin, rosin ester and other rosin derivatives, polyterpene resin, oil-soluble phenol resin, petroleum hydrocarbon resin, etc. Filler: zinc oxide, titanium oxide, calcium carbonate,
Clays, various pigments (colorants), etc. Softeners: mineral oil, liquid polybutene, lanolin, etc. In addition, various additives such as antioxidants may be added. The synthetic resin paste layer 4 may be made of various synthetic resin pastes such as vinyl chloride resin, acrylic resin, and ethylene / vinyl acetate copolymer. The synthetic resin paste contains a synthetic resin as a main component, a plasticizer, a stabilizer, a filler, and the like. It may be colored by a coloring agent. A blowing agent such as azodicarbonamide may be added. Synthetic resin paper
The strike layer 4 has a pattern layer 5 as wallpaper.
Print printing or squeezing is performed on the surface. Print printing can be performed in various printing formats, and a pattern can be printed by printing using gravure printing, screen printing, or the like. The printing may be not only one color but also several colors of overprinting. An uneven pattern or the like can be formed by squeezing using a squeezing roll or the like. The top coat layer 6 penetrates the picture pattern and prevents the transfer of its constituents, such as a plasticizer, from the paste layer 4, for example, a vinyl chloride resin paste. Between them. Examples of the topcoat agent constituting the topcoat layer 6 include acrylic resin-based, vinyl chloride-acrylic copolymer-based, silicone-acrylic copolymer-based, and polyurethane-based surface treatment agents. The top coat agent has a synthetic resin as a main component, a solvent and an additive. It may be colored by a coloring agent. A coating film is formed by top coating. As described above, since the pressure-sensitive adhesive layer 2 is provided with the dry-type pressure-sensitive adhesive layer 2 and the top-coat layer 6 has a release property from the pressure-sensitive adhesive layer 2, the pressure-sensitive adhesive layer 2 and the top-coat layer 6 Can be easily peeled off without the need for the interposition of a release paper adhesion preventing member.

According to the manufacturing method, for example, as shown in FIG. 1B, first, a synthetic resin paste 4
0, and dried to form a synthetic resin paste layer, a pattern layer is formed on the paste layer by, for example, printing or squeezing 50, and a top coat is formed on the surface of the paste layer. The adhesive 60 is coated to form a top coat layer, and then the adhesive 20 is coated on the opposite surface of the substrate 30 to laminate the adhesive layer. The adhesive-backed wallpaper having the holes 7 is wound up. After laminating the pressure-sensitive adhesive layer, winding may be performed without performing perforation 70, and then perforation 70 may be performed. The perforation 70 can be performed by, for example, a needle cloth roll. Perforated 70
Is provided with a large number of fine holes from the outer surface of the pressure-sensitive adhesive layer 2 to the surface of the wallpaper 1 so as to penetrate in the thickness direction. The obtained wallpaper 1 with an adhesive is rolled up as shown in FIG. 1 (D). Therefore, there is no need for the interposition of an adhesion preventing member such as a release paper or a plastic film for preventing the adhesion between the pressure-sensitive adhesive and the wallpaper surface, in which the pressure-sensitive adhesive layer 2 and the top coat layer 6 are in direct contact with each other, and the water is wet. This is a roll-type dry type pressure-sensitive adhesive wallpaper which does not require the adhesive. The pressure-sensitive adhesive wallpaper 1 may have any appropriate width.
However, the pressure-sensitive adhesive-equipped wallpaper having the through-holes 7 of the present invention is more effective in preventing swelling as the width is wider. That is,
When the width is relatively small, the swelling phenomenon is not so large, but as the width increases, the swelling phenomenon becomes more conspicuous.

[0010]

The present invention will be further described below with reference to examples.

Example 1 A polyvinyl chloride paste having the following composition (parts in the composition ratio is parts by weight; the same applies hereinafter) was applied to the surface of yellow flame retardant paper for vinyl wallpaper. Formulation: Polyvinyl chloride paste resin 100 parts DOP (dioctyl phthalate) 40 parts Calcium carbonate 30 parts Stabilizer 4 parts Then, a pattern is printed on the surface of the foamable polyvinyl chloride paste using a printing ink having the following composition.

Although the invention made by the present inventor has been specifically described based on the embodiments, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the gist of the invention. Needless to say,

[0013]

The effects obtained by the representative ones of the inventions disclosed in the present application will be briefly described as follows. That is, according to the present invention, it is possible to provide a technique capable of preventing (1) swelling of the wallpaper with the adhesive when the wallpaper is adhered to the base via the adhesive layer. Further, according to the above embodiment, there are the following advantages. (2) In the wallpaper with the adhesive, the adhesive layer and the top coat layer can be easily peeled off. The adhesive layer and the top coat layer are easily separated from each other without the necessity of intervening an anti-adhesion member such as a release paper or a plastic film for preventing the adhesion between the adhesive and the wallpaper surface as in the conventional example. Can be. (3) When installing the wallpaper, the time required for peeling off the anti-adhesion material such as the release paper or the plastic film as in the conventional example is not required, so that the installation time can be shortened. That is, it is possible to directly apply wallpaper while peeling off the adhesive layer and the top coat layer, thereby facilitating the construction and significantly reducing the construction time. (4) In addition, when the wallpaper is installed, it does not require water wetting as in the conventional example, so that it does not require much trouble when used.
The construction time can be reduced. (5) In the conventional example, when the release paper is interposed as described above, the adhesive layer has an adhesive force enough to interpose the release paper, so that the release paper is once attached to the wall surface. Later, even if you try to re-paste, there is a disadvantage that it is difficult to peel off, and if you try to forcibly peel off, there is also a disadvantage that the material of the wall is peeled off, but according to the present invention, the paste of the wallpaper Since it is composed of a pressure-sensitive adhesive layer having an initial adhesive strength that can be repaired, it can be re-applied after pasting once. (6) According to the present invention, the top coat layer not only has an easy release property from the pressure-sensitive adhesive layer as described above, but also the top coat layer has a lower synthetic resin. Pe
For example, when the synthetic resin paste layer is a vinyl chloride resin paste containing a plasticizer, the transfer of the plasticizer can be prevented because the transfer of the constituent components migrating from the paste layer can be prevented. By blocking, it is possible to suppress stickiness and the like on the wallpaper surface. (7) According to the present invention, since there is no need for the interposition of an adhesion-preventing member such as a release paper or a plastic film for preventing the adhesion between the pressure-sensitive adhesive and the wallpaper surface as in the conventional example, such The process can be omitted, and the production cost and the wallpaper cost can be reduced because no release paper or plastic film is required. (8) According to the present invention, since the formation of the pressure-sensitive adhesive layer is performed by a coating method, no special equipment such as a conventional transfer method is required, which is advantageous in terms of cost, and is advantageous in manufacturing. However, unlike the conventional example, it is not necessary to take a complicated step of applying the adhesive at one end to the release paper side and transferring it to the base material side. (9) According to the present invention, a wallpaper with an adhesive wound in a roll is obtained. As described above, the adhesive layer and the top coat of the wallpaper with the adhesive wound in the roll are obtained. While peeling off the layer, the layer can be cut and pasted to an appropriate length, and the construction is easy. (10) The top coat layer of the present invention is clear, and the pattern layer of the synthetic resin paste layer under the top coat layer is raised, so that the aesthetic appearance as wallpaper can be enhanced.
