Description

  The present invention relates to a decorative seal having both thinness and flexibility, and a method for manufacturing a decorative seal. More specifically, the present invention relates to a base material (base paper or base film) by inkjet printing that forms an image with an ultraviolet curable ink. Etc.), and by applying three types of UV curable inks with different functionality on the release sheet in a layered manner, it has both thinness and flexibility, which is particularly useful as a nail seal for nails. The present invention relates to a decorative seal and a method for manufacturing a decorative seal that can be easily produced.

  In recent years, manicures that have been colored by conventional brush painting have evolved, and nail art that gives favorite colors and patterns to nails and the like has become widespread. In addition, it has been widely practiced to individually decorate mobile phones, multifunction mobile phones, and products such as stationery, furniture, and home appliances according to user preferences. As means for imparting a coloring or pattern by a method other than manicure for painting a nail or the like, which has been a target for a long time, the following are common. A method of sticking a decorative seal in which a decorative layer is formed by printing on a base film or the like provided with an adhesive layer to an object such as a nail (see Patent Document 1, etc.) or offset printing on a support sheet Then, a transparent layer, a pattern layer, and a white layer are laminated in that order, and a transfer seal provided with an adhesive layer thereon is used, and the adhesive layer side is placed on the object and rubbed from above the support sheet. There is a method of transferring a picture by peeling a sheet (see Patent Document 2). In addition, with the aim of providing a nail seal that can be applied well to nails (curved surfaces), a transparent top is formed through a base layer formed by applying a specific aqueous resin liquid on the adhesive layer. There is also a proposal for a nail seal in which an adhesive layer and a top layer are integrated with each other via a base layer by providing a layer (see Patent Document 3). In particular, for nail seals, for example, a structure that enables three-dimensional decoration (see Patent Document 4), and further, as a method of manufacturing an artificial nail having a three-dimensional shape, an artificial nail material is used with an inkjet printer. Proposals have also been made for printing patterns (see Patent Document 5), and various decorative forms have been realized.

Japanese Patent No. 4953396 JP 2004-337601 A Japanese Patent No. 4324241 JP 2007-068621 A Japanese Patent No. 49435592

  However, contrary to the trend of three-dimensional decoration with seals as described above, it is of course possible to use it for decoration of various products. In particular, nail seals are used daily instead of the conventional manicure for brush painting. On the other hand, it should be a thin decorative seal that does not feel as thick as possible so that the functionality of the product and the movement of the fingertips are not impaired by decoration. It is desired. On the other hand, many of the conventional decorative seals have a configuration in which printing is performed on a resin film (base material) to which the above-mentioned adhesive is pasted. Even if the material is used, the thickness and hardness of the base film is inevitable, difficult to stick along the nail curve, especially when sticking to large areas, and after that the seal surface There has been a problem that it is difficult to coat the topcoat solution for protection. Above all, the wrinkles that occur at the time of sticking greatly impair the design, so there is a situation where it is necessary to make a partial seal instead of a large area seal that covers the entire nail. Development of a large-area decorative seal that is less likely to cause wrinkles is desired. Conventional seals with a pattern on the pressure-sensitive adhesive layer also require a function as a base material, so the pressure-sensitive adhesive layer needs to be thick, and the purpose of reducing the thickness of the decorative seal can be achieved. It wasn't. In addition, the sheet having a structure for transferring a pattern to an object such as a conventional nail can be thinner than the type of printing on a base material, but the stack of seals is required to enable transfer. In addition to the complexity of the structure, it is difficult to transfer all thin patterns to the curved surface of the nail in a good state using a transfer sticker, and there are many cases where the transfer fails. It would be extremely useful if a decorative sheet capable of forming a thin pattern on an object such as a nail with a simple structure and simple operation was developed.

  Therefore, the object of the present invention is not a method for transferring a picture, and the thickness of the picture part of the sticker is a decorative seal having a simple layer structure without using a base material that causes the thickness to increase. Providing a decorative thin sticker that is durable and has an unprecedented thickness that can be used to form patterns and colors with a simple operation while being large in area. Furthermore, it is providing the manufacturing method of the decorative seal | sticker which can obtain the said outstanding decorative seal | sticker simply.

  The above object is achieved by the present invention described below. That is, the present invention comprises an adhesive primer layer printed with an ultraviolet curable primer ink formed by printing on a release sheet, and formed by printing on the primer layer, at least A pattern layer (including multiple layers) consisting of UV curable color ink and UV curable white ink used as required, and a clear coat layer printed with UV curable clear ink A decorative seal is provided.

  The following is mentioned as a preferable form of the decorative seal of the present invention. The clear coat layer is provided in a wider range than the range in which the primer layer is provided, and the thickness of the clear coat layer in the wide range portion is 20 μm or more; The thickness of the portion where the primer layer, the pattern layer, and the clear coat layer are laminated is 40 μm or less.

  Another embodiment of the present invention is an ink jet printer that forms an image with an ultraviolet curable ink, wherein an adhesive primer layer is printed on a release sheet using an ultraviolet curable primer ink, and the primer layer On top of this, a desired pattern is printed using at least an ultraviolet curable color ink and, if necessary, an ultraviolet curable white ink, and a pattern layer (including a case where it is formed in multiple layers), and an ultraviolet curable type The present invention provides a method for producing a decorative seal, wherein a clear coat layer is formed by printing using a clear ink.

  As a preferred embodiment of the method for producing a decorative seal of the present invention, the ultraviolet curable primer ink is a compound selected from an acrylate oligomer, an acrylate monomer, and an oxetane cationic polymerization type monomer, a photopolymerization initiator and an adhesive. It can be added with a property-imparting agent, and when the seal obtained by printing with the ink jet printer is peeled off from the release sheet, the formed primer layer can impart adhesiveness to the seal. It is done.

  According to the present invention described above, the thickness of the pattern portion of the seal can be extremely reduced while it is not a system for transferring a pattern and is a decorative seal having a simple layer configuration without using a base material. It is possible to provide a durable and thin decorative seal that can be used to form a pattern or color with a simple operation even if it is a large-area seal. The method makes it possible to provide an excellent decorative seal as described above. According to its preferred form, it is a very thin decorative sticker with a large area, but it is also easy to handle, and when used for decoration such as nails, it can be easily and in good condition with no wrinkles on its surface. It can be integrated, and after applying the seal, the operation when applying the top coat solution to improve the durability of the seal surface with a brush can be easily performed. The imparted coloring and pattern can be easily made to have a high durability as well as being excellent in design without wrinkles.

More specifically, the following effects can be obtained.
(A) The primer layer, the ink pattern layer and the clear coat layer constituting the decorative seal of the present invention are each formed by printing directly on the release sheet with an ink jet recording apparatus. For this reason, the thickness is extremely thin, which is kept to a minimum that has never been achieved. For example, in the case of a nail seal, the thickness of the portion where the primer layer, the pattern layer, and the clear coat layer, which are the portions that decorate the nails, is 40 μm or less, and if desired, an extremely thin seal of about 25 μm It is also possible to do.
(B) Since the decorative seal of the present invention does not require a base material as in the prior art, it is obviously thinner by the amount of the base material than a seal of the type that required a conventional base material (film or the like). It becomes a flexible seal. For this reason, in use, a series of operations of applying a seal and coating the applied seal surface with a topcoat solution can be easily performed in a good state and excellent in usability.
(C) Since the decorative seal of the present invention has both thinness and flexibility, it is difficult for the wrinkles at the time of sticking with the curved surface of the nail to be moved. Nail seals that could only be applied can be applied to the entire surface of the nail, and as a result, decorations that represent more diverse designs can be realized.
(D) By using the decorative sticker of the present invention, it is possible to easily apply a very thin sticker with various design patterns and various colors on the entire surface of the nail in a good state. There is no need to paint a base color or draw art as it was done, and the decorative seal of the present invention can be used as a nail seal so that the base color and the art on it can be done in one step. This makes it possible to easily decorate nails with excellent design.
(E) The decorative seal of the present invention can be easily manufactured in the same manner as normal printing using an ink jet printer that forms an image with an ultraviolet curable ink. As a result, the width of the design of the decorative seal obtained can be remarkably varied. Furthermore, since the thickness of the ink layer to be formed can be freely controlled in ink jet printing, the portion that becomes the handle of the decorative seal with a thick layer can be easily and simultaneously with the formation of the pattern layer or continuously. Can be formed. Furthermore, for example, it is easy to form the thickness of the portion that becomes the edge of the pattern layer by ink-jet printing, and the strength of the edge portion can be improved if configured in this way. The operation when the decorative seal of the present invention is peeled off is used more smoothly.

It is a figure which shows an example of the decorative sticker of this invention. It is typical AA sectional drawing of the seal | sticker of FIG. It is typical BB sectional drawing of the seal | sticker of FIG. It is the figure which showed typically an example of operation in the case of decorating a nail | claw using the seal | sticker of FIG.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings, taking a nail seal as a preferred example of the seal of the present invention. As a procedure for producing the decorative seal of the present invention used for the decoration of the nail shown in FIGS. 1 and 2, for example, it can be easily produced as follows.

Each layer is directly printed on the release sheet (1) in the following order using an ultraviolet curable ink jet printer and each ultraviolet curable ink having a function for forming each layer.
First, it is necessary to print and form the primer layer (2) on the release sheet (1) with an ultraviolet curable primer ink. In the seal illustrated in FIGS. 1 and 2, the pattern layer is further printed on the formed primer layer (2) using an ultraviolet curable color ink and, if necessary, an ultraviolet curable white ink. (3) is formed. The pattern layer (3) may be a multilayer composed of a plurality of layers. For example, when a pattern formed with various color inks has a clear design, it is formed on the bottom layer of the plurality of pattern layers. A white undercoat layer formed using white ink is formed, and a pattern is formed thereon with color ink to form a multilayer.

  In the seal illustrated in FIGS. 1 and 2, the decorative seal of the present invention is manufactured by subsequently printing on the surface using an ultraviolet curable clear ink to form a hard clear coat layer (4). To do. By forming the hard clear coat layer (4) in the laminated structure, for example, it is possible to prevent seal warpage or wrinkles that may be caused by the white ink used for forming the pattern layer (3). Moreover, since the clear coat layer (4) is hard, the effect of preventing scratches can be obtained by printing on the entire uppermost portion. However, the clear coat layer does not necessarily have to be formed on the uppermost portion. For example, the clear coat layer (4) may be under or between the picture layers (3) (not shown). Although the strength is somewhat lower than when it is formed on the uppermost part, the hard clear coat layer (4) is formed in the laminated structure constituting the decorative seal of the present invention. It can be a decorative seal that can be used.

  In a preferred embodiment of the present invention, by performing printing as described below, the decorative seal structure can be formed with a so-called handle portion, which is applied from a release paper during use. The operability when peeling off the seal portion can be improved. Specifically, when the clear coat layer (4) is formed by printing using the above-described clear ink, for example, as shown in FIG. 1, from the range where at least the primer layer (2) is provided. Further, a clear coat layer (4) is provided over a wide range, and as shown in FIG. 3 (A), the thickness of the clear coat layer (4) in the wide range portion is the thickness of the primer layer (2). And the thickness of the pattern layer (3) are preferably formed so as to function as a handle. Further, as another method for forming the handle, it can be easily formed as shown in FIG. Also in this case, as shown in FIG. 1, it is the same as the above case that the clear coat layer (4) is provided over a range wider than the range where the primer layer (2) is provided. As shown in (B), the range in which not only the clear coat layer (4) but also the pattern layer (3) is provided is made wider than the range in which the primer layer (2) is provided. In this case, as shown in FIG. 3B, by increasing the thickness of the pattern layer (3) by at least the thickness of the primer layer (2), this portion of the pattern layer (3 ) And the clear coat layer (4) form a portion having a sufficient thickness to function as a handle. As another method for forming the handle, it can be easily formed as shown in FIG. Also in this case, as shown in FIG. 1, it is the same as described above that the clear coat layer (4) is provided over at least a range wider than the range where the primer layer (2) is provided. As shown in (2), by further increasing the thickness of the clear coat layer (4) that becomes the handle, a portion having a sufficient thickness to function as the handle is formed.

  In the above, the specific method for adjusting the thickness of the layer necessary for forming a part that becomes a handle thicker than the other part uses the above-described ultraviolet curable ink jet printer, and the printing conditions thereof If it adjusts, it can form easily. In other words, in the same manner as in the case of forming a dark image, an area portion that needs to be thickened can be very easily and similarly to normal image formation by increasing the number of dots of ink applied to the area. It can be formed by the operation. In this way, the ink can be formed by controlling the amount of ink in the printing area, similarly to recording an image of a light and shade part using the same ink as that for forming other parts. Another method is to increase the concentration of the ink used to form the area that needs to be thicker to the maximum, and to increase the concentration compared to the ink used to form other regions of the layer. It can be easily formed by using.

  When the decorative seal of the present invention is used for nail decoration as a nail seal, it is preferable to do the following (see FIG. 4). First, it is preferable that the nail is pretreated with a gel or a base coat. Then, a nail seal having a desired pattern and color is selected, the handle portion formed as described above is picked and peeled off, and the nail seal primer layer (2) is peeled off on the nail that has been ground. Adhere so that the side is the surface of the nail. Thereafter, the above-mentioned handle portion is taken, and further, an excess portion having a nail seal larger than the nail is cut off with scissors. Then, after firmly sticking the seal to the surface of the nail, the seal surface is coated with a top gel or a top coat solution. If it does in this way, the decoration to the nail | claw with stronger design nature with a topcoat etc. will be attained.

Next, the material for forming each layer constituting the decorative seal of the present invention will be described.
(Peeling sheet)
There is no particular limitation, and commercially available release paper (including synthetic resin films) in general can be used. For example, an inexpensive type in which paper is coated with a silicone release agent can be suitably used.

(Primer layer)
UV curable ink for inkjet that is compatible with commercially available UV curable inkjet printers can be used, but in the present invention, when the decorative seal is peeled off from the release sheet, the primer layer has adhesiveness Therefore, it is necessary to use an adhesive type ink among commercially available products. In order to give such a layer formed by printing, the ink used is, for example, an acrylate oligomer or an acrylate monomer, or an oxetane cationic polymerization type monomer such as 2-ethylhexyl oxetane, An ultraviolet curable ink or the like to which a photopolymerization initiator, a tackifier or the like is added can be used. For example, a thickness of the primer layer of about 10 to 15 μm is sufficient.

(Picture layer)
An ultraviolet curable ink for ink jet (hereinafter referred to as UV ink) suitable for an ink jet printer commercially available from each company can be used. Examples of the forming component include those containing a monomer or oligomer having an acrylate group as a resin of the binder, a polymerization initiator, and a pigment. In UV curable ink jet printing using UV ink, any commercially available UV ink can be used, but non-aqueous UV ink is preferred. The non-aqueous UV ink used in the present invention is not particularly limited, and is newly prepared by dispersing a pigment in a commercially available non-aqueous UV ink, or a photopolymerization composition combining a photopolymerization monomer alone or a photopolymerization oligomer. Any non-aqueous UV ink can be used. Further, it is particularly preferable to use a material containing urethane acrylate as a binder resin forming material. This is because urethane acrylate is soft and easily follows a curved surface such as a nail. The thickness of the pattern layer formed with these inks is, for example, about 2 to 20 μm, although it varies depending on the type of the pattern and whether or not the white layer is formed as a pattern base with white ink. Furthermore, the white layer can be formed in a range wider than the range in which the pattern is provided, and this can be a part of the handle described later.

(Clear coat layer)
Of the ultraviolet curable inks for inkjet that are compatible with the commercially available ultraviolet curable inkjet printers, any of the highly transparent inks that are commercially available for topcoats can be used. For example, what contains the monomer or oligomer which has an acrylate group as resin of a binder, and a polymerization initiator is mentioned. In particular, when the applied seal surface is used as a decorative seal that is not coated with a top gel or a top coat solution, the clear coat layer that constitutes the decorative seal has a hardness or the like. It is preferable to use an ink that has a substrate-like property. Further, the scratch resistance of the seal can be made sufficient by printing the clear coat layer on the top of the decorative seal. The thickness of the clear coat layer in the case of printing on the uppermost part is sufficient, for example, about 1 to 5 μm. The ink used for forming the clear coat layer, when the handle portion is formed, has a thickness of the handle portion of 20 μm or more, for example, about 25 μm to 40 μm. It was confirmed.

EXAMPLES Next, although an Example and a comparative example are given and this invention is demonstrated further in detail, this invention is not limited to these Examples.
An inkjet printer UJF-3042HG manufactured by Mimaki Engineering Co., Ltd., which is a UV inkjet printer, was used, and WG-80 manufactured by Lintec Corporation was used as the release paper (1). And by the following procedure, it printed directly on this release paper with the said UV inkjet printer, and produced the nail seal. Here, the film thickness was measured by a digital film thickness meter manufactured by Mitutoyo Corporation: Micrometer MDC-25M.

[Example 1]
First, on the release paper (1), PR-100 (manufactured by Mimaki Engineering Co., Ltd.) is used as a UV primer ink, and the primer layer (2 ) Was formed. The thickness of the primer layer was measured to be about 15 μm. Next, LF-140W (manufactured by Mimaki Engineering Co., Ltd., UV curable ink cartridge) is used as the white ink on the formed primer layer (2), and each color of LF-140 [manufactured by Mimaki Engineering Co., Ltd.] as the color ink. , UV curable ink cartridge] was used to print a flower pattern (pattern layer (3)). When the film thickness of the pattern layer was measured, it was about 2 to 6 μm.

  Next, using LH-100Cl (manufactured by Mimaki Engineering Co., Ltd., UV curable ink cartridge clear) as a clear ink, a nail-shaped portion formed with a primer layer (2) and a pattern layer (3), The clear coat layer (4) was formed by printing as follows on the part to be the handle. That is, the nail-shaped portion had a halftone dot of 5%, the handle portion had a halftone dot of 100%, continuous printing was performed twice, and a clear coat layer (4) was formed on the entire seal surface. When the film thickness of the clear coat layer was measured, it was 1 to 2 μm at the nail-shaped portion and about 25 μm at the handle portion. As described above, a nail seal having a large area that can cover the entire nail with the configuration shown in FIGS. 1 and 3A by printing the portion to be a handle with clear ink having the maximum density. Was made. As shown in FIG. 2 (A), the decorative sticker for the flower pattern formed on the release paper (1) as described above has an adhesive primer layer, a pattern (pattern layer), and a clear coat. The layers were integrated, and the thickness of the nail seal was about 25 μm, which was confirmed to be much thinner than the conventional nail seal of the same kind (80 μm or more).

[Example 2]
In Example 1, one layer before printing the floral pattern, using the same white ink as used in Example 1, and using the same range as the primer layer (2) formed on the release paper (1), a halftone dot of 50% A nail seal of this example was prepared in the same manner as in Example 1 except that a white layer (film thickness of about 12 μm) was formed by printing (see FIG. 2B). In the obtained nail seal, the thickness of the nail-shaped portion was about 37 μm, and a clearer pattern was obtained.

Example 3
In Example 2, the range of the white layer formed with the white ink before printing the floral pattern was printed at the same range as the primer layer, and subsequently the portion to be held with a halftone dot of 50%. A seal was prepared in the same manner as in Example 2 except that a white layer (film thickness of about 12 μm) was formed (see FIG. 3B). The nail seal had a nail thickness of about 37 μm and a handle thickness of about 37 μm.

[ Reference Example 4]
In Example 2, except that the clear coat layer (4) formed using the clear ink was formed by printing between the white layer formed before printing the floral pattern and the floral pattern printing. A seal was prepared in the same manner as in Example 2 (not shown). The thickness of the nail portion of the nail seal was about 32 μm.

[Comparative Example 1]
A nail seal was prepared in the same manner as in Example 3 except that the clear coat layer was not formed in Example 3. The thickness of the nail-shaped portion of the nail seal was about 35 μm, and the thickness of the portion to be the handle was about 12 μm.

(Evaluation)
The flower pattern nail seals produced in Examples 1 to 3, Reference Example 4 and Comparative Example 1 were used and evaluated as follows. Specifically, the flower pattern nail seal was peeled off from the release paper and applied to the nail that had been pretreated with gel. At that time, all of Examples 1 to 3 and Reference Example 4 were able to easily peel off the seal from the release paper. And when the state which stuck each seal | sticker of Examples 1-3 and Reference Example 4 to the nail | claw was observed visually, the nail art excellent in the design property which does not have a wrinkle as an external appearance was able to be produced over the whole nail | claw. Moreover, when the seal | sticker stuck on the nail | claw was scratched strongly with the nail | claw, although the nail seal | sticker of the reference example 4 was scratched, the nail seal | sticker of Examples 1-3 was also able to endure the nail | claw scratch. However, with the seal produced in Comparative Example 1, the seal was greatly curled and rounded when peeled off from the release paper, and could not be applied to the nail in a good state.

  The decorative sticker of the present invention can be easily manufactured in the same manner as normal printing using an ink jet printer that forms an image with an ultraviolet curable ink. Or a desired photographic image. As a result, the width of the design of the decorative seal obtained is remarkably diverse and diverse. Furthermore, when manufactured using ink jet printing, the thickness of the layer to be formed can be freely controlled, so that the formation of a thick handle part of the decorative seal can be simplified. If the portion that becomes the edge of the pattern layer is formed thicker, the strength of the edge portion can be easily improved without affecting the pattern, so that a decorative seal with a smoother peeling operation can be obtained. The decorative seal provided by the present invention is suitable for nails. However, as described above, a variety of various seals can be easily produced. Therefore, the present invention is not limited to this, and other uses include mobile phones and the like. It is useful as a decoration for products such as equipment, stationery, furniture, and home appliances. And by simply sticking the decorative sticker provided by the present invention to these items as appropriate, the design can be improved, and these products are products with unique designs that more closely match the needs of users. At the same time, since the thickness of the seal is thin, and a seal having an appropriate shape with a desired large area can be obtained easily, it is expected to be used as a beautiful protective sheet for the products listed above.
