The dimensional ratios in the drawings shown below are different from actual ones for the convenience of the description.

First Embodiment
FIG. 1 is a schematic cross-sectional view of a joint tape according to a first embodiment of the present invention. FIG. 2: is a schematic cross section which shows the joint part processed by the processing method of the joint part using the tape for joints of this embodiment, and its vicinity.
In the joint tape 10 of the present embodiment, a plurality of wall materials 41 are juxtaposed, a coating 43 (decorative layer) of the first paint is provided on the surface 41 a of each of the plurality of wall materials 41, and adjacent walls In the structure 40 in which the joint material 47 is filled in the joint portion 45 between the members 41 and the joint material 47 is exposed, the tape is stuck on the joint material 47.

<Structure>
The structure 40 includes a plurality of wall materials 41 juxtaposed. As such a structure 40, the outer wall, inner wall, etc. of a building are mentioned, for example.
It does not specifically limit as the wall material 41, The thing according to the structure 40 can be selected suitably, For example, an outer wall board etc. are mentioned.
Examples of the material of the wall material 41 include ceramic-based siding, lightweight cellular concrete, and the like.

A joint 45 is provided between the adjacent wall members 41. The joint 45 is a gap between the adjacent wall members 41.
In the present embodiment, the wall material 41 has a surface 41 a on which the coating 43 of the first paint is provided, and a side surface 41 b extending from both side edges of the surface 41 a to the back surface of the wall material 41. Adjacent wall members 41 are disposed on a base (not shown) with the side surfaces 41 b separated from each other, and joint portions 45 are formed by the side surfaces 41 b of the respective wall members 41.

  The joint portion 45 is filled with the joint material 47. The joint material 47 is used to improve the waterproofness, airtightness and the like of the structure 40. The joint material 47 is not particularly limited, and can be appropriately selected from well-known joint materials such as caulking materials and sealing materials.

The coating film 43 of the first paint is provided on the surface 41 a of the wall material 41.
On the other hand, the joint material 47 is exposed. That is, when the structure 40 is viewed from the front side (the coating 43 side of the first paint), the joint material 47 is visually recognized. Therefore, the coating film 43 of the first paint is not provided on the joint material 47.
Such a structure 40 typically uses the wall material 41 coated with the first paint on the surface 41 a in advance in a factory or the like when a plurality of wall materials 41 are juxtaposed at the site where the structure 40 is constructed. Thereafter, the joint portion 45 between the wall members 41 is constructed by filling the joint member 47.

The coating 43 of the first paint is a decorative layer, and usually has some pattern (pattern).
As a pattern, the scattering pattern etc. which are formed from a multi-colored paint, for example are mentioned.
As the first paint, a coating film having a desired pattern may be formed, and the first paint can be appropriately selected from paints conventionally used for decorating wall materials and the like.
The first paint usually contains a resin component. As the resin component, for example, two or more of acrylic resin, acrylic silicone resin, polyvinyl acetate, polystyrene, acrylonitrile polymer, Baoba (branched fatty acid vinyl ester) polymer, natural or synthetic rubber, and monomers forming these resins And the like. These resins may be in the form of resin emulsions.

As the coating 43 of the first coating, a coating of single color or multicolored pattern including one or two or more colors of gel-like colored particles in which the coloring coating is wrapped by a gelation film (hereinafter also referred to as “pattern coating”. Is preferred. The patterned coating film has a complex pattern in which fine gel-like colored particles are intricately incorporated, and the surface has fine irregularities and is excellent in design.
The patterned coating film containing gel-like colored particles in one color is a coating film of a single color, and the patterned coating film containing two or more colors of gel-like coloring particles is a coating film of multiple colors (that is, multicolored patterns).
The patterned coating is formed of a paint containing gel-like colored particles in one or more colors.
The patterned coating will be described in detail later.

  The mass per unit area of the coating 43 of the first paint is not particularly limited.

<Joint tape>
The joint tape 10 of the present embodiment includes a substrate 1 and a coating 3 of a second paint provided on the substrate 1.

(Base material)
The substrate 1 is used to give strength to the joint tape 10.
The material of the base material 1 is not particularly limited as long as the coating film 3 of the second paint can adhere thereto. Preferred examples include cellophane, nylon, polyester resin, acrylic resin and the like. Among these, acrylic resins are preferable in terms of weather resistance.
The thickness of the substrate 1 is not particularly limited.

(Coating of second paint)
The appearance of the coating 3 of the second paint is substantially the same as the appearance of the coating 43 of the first paint. For example, when the coating 43 of the first paint has a handle, the coating 3 of the second paint has a handle substantially the same as the handle. Therefore, the joint tape 10 has an appearance substantially the same as the appearance of the coating 43 of the first paint.
The “substantially the same” indicates that they are identical or approximate. The term “approximated” means that the joint tape 10 and the coating film 43 of the first paint, when visually observing the joint area treated by the joint tape treatment method using the joint tape 10 and the vicinity thereof. Show that the appearance differs within the range in which there is no discomfort due to the difference in appearance.

As the second paint, it is sufficient if it can form a coating having an appearance substantially the same as the appearance of the coating 43 of the first paint, and as in the first paint, it is conventionally used for decorating wall materials It can be selected as appropriate from among the existing paints.
The second paint usually contains a resin component as well as the first paint. Examples of the resin component include the same as those described above.
The second paint may be the same paint as the first paint or may be a paint different from the first paint as long as the appearance of the formed coating is substantially the same. For example, it is the same paint as the first paint, or the component contributing to the formation of the handle (for example, the above-mentioned gel-like colored particles) is the same, and the content of the component is the same. It is preferable that the paint be similar.

  When the coating 43 of the first coating is a patterned coating, the coating 3 of the second coating is also preferably a patterned coating. Conventional cosmetic tapes are generally printed on a substrate. As described above, the pattern coating film has a complex pattern in which fine gel-like colored particles are intricately intermingled, and since there are fine irregularities on the surface, the appearance of the pattern coating film is substantially identical to that of the pattern coating in printing. It is difficult to reproduce the appearance. Therefore, when the joint portion is treated with the conventional cosmetic tape, it is easy to give a sense of discomfort. By making the coating film 3 of the second paint into a patterned coating film, the effect of reducing discomfort when the joint portion is treated is large.

When the coating 43 of the first coating and the coating 3 of the second coating are both pattern coatings, gel-like colored particles of one or more colors contained in the coating 3 of the second coating are: It is preferable that it is the same as the gel-like colored particle contained in the coating film 43 of a 1st coating material. When the gel-like colored particles are two or more colors, it is preferable that the ratio of each gel-like colored particle is also the same.
The difference in the content of gel-like colored particles between the coating 43 of the first paint and the coating 3 of the second paint is preferably as small as possible in terms of appearance, and may be 0% by mass. The content of gel-like colored particles is the ratio of the mass of gel-like colored particles to the total mass of the coating.

  The mass per unit area of the coating film 3 of the second paint is not particularly limited, but if the appearance is sufficient, it is preferable that the coating film is thin enough to open a hole and make an opening. If the coating film has an opening, air stagnation is difficult to occur at the time of sticking. Even if the hole is open, there is no problem because the adhesive is used to close the resin component similar to the first paint used at the time of application.

(Elasticity of joint tape)
The joint tape 10 preferably has stretchability. In the joint portion 45, the width of the joint portion 45 may be temporarily expanded due to an earthquake, temperature change, or the like, and the joint material 47 may be expanded. If the joint tape 10 stuck on the joint material 47 has stretchability, the joint tape 10 follows when the joint material 47 is stretched, and both sides of the joint tape 10 and the wall material It can suppress that the joint material 47 is exposed between the side edges of the surface 41 a of the surface 41 a, and can keep only the generation of a narrow gap even if it is exposed. Further, when the width of the joint portion 45 is returned to the original, the width of the joint tape 10 is restored to the original, so that it is possible to maintain a good appearance without wrinkles and the like.

(Method for manufacturing joint tape)
The joint tape 10 is obtained by applying a second paint on the substrate 1.
The coating of the second paint can be performed by a known method. For example, the second paint may be applied on the substrate 1 and dried.
The application method is not particularly limited, and for example, known application methods such as a brush, a trowel, a roller, and a spray can be used. Drying may be normal temperature drying or heat drying.

<Method of processing joints>
The method of treating the joint portion 45 using the joint tape 10 has a step of sticking the joint tape 10 on the joint material 47 filled in the joint portion 45.
Since the joint tape 10 has an appearance substantially the same as the appearance of the decorative layer 43 on the surface of the wall material 41, the joint tape 10 is stuck on the joint material 47, so that the wall material 41 is not coated. It is possible to add a feeling of incongruent decoration with the decorative layer 43 at the joint portion between them.

In the present embodiment, the bonding of the joint tape 10 onto the joint material 47 is performed via the adhesive layer 50.
The adhesive layer 50 usually contains a resin component. The resin component contained in the adhesive layer 50 is preferably the same type of resin as the resin component contained in the coating 3 of the second paint. For example, when the resin component contained in the coating film 3 of a 2nd coating material is an acrylic resin, it is preferable that the resin component contained in the contact bonding layer 50 is also an acrylic resin.

<Function effect>
In the present embodiment, by using the joint tape 10, it is possible to add a decoration without discomfort to the joint 45 between the wall materials 41 already decorated without painting.
That is, since the joint tape 10 has substantially the same appearance as the decorative layer 43 provided on the surface of the wall material 41, the joint tape 10 is attached to the joint material 47 without painting. The appearance of the joint 45 can be made substantially the same as the appearance of the decorative layer 43.
