Description

Image transfer method to balloon, balloon

The present invention relates to an image transfer method for transferring and printing an image of any design, photograph, character, etc. on the surface of a balloon generally used for toys, event ornaments, display ornaments, etc. Concerning the transferred balloon.

Techniques such as water transfer, thermal transfer, sublimation transfer, and dry transfer are known as transfer printing for transferring an image to a transfer object. In particular, dry transfer, in which an adhesive is applied to the back surface of an image layer temporarily attached to a base sheet and then the image layer is transferred to the surface of a transfer object by pressing and adhered, the edges remain on the image during transfer. Therefore, it appears to be printed directly on the transfer object, and there is a feature that no post-processing by a cutting plotter or the like is required.

As such a transfer sheet for dry transfer and a method for producing the same, a prior art (hereinafter referred to as “prior art”) such as a dry transfer paper described in Patent Document 1 and a method for producing the same is proposed. According to such a prior art, since the adhesive is not applied to the region other than the image layer, there is an advantage that the transfer object is not contaminated. However, since the prior art includes a process in which the image layer is converted into a light shielding image and then the photosensitive material is modified and cured by an exposure process, the image layer naturally has to shield light, and the color of the image And the color tone must be constrained. In addition, the process of light irradiation to the photosensitive material, the process of removing the uncured photosensitive material with a solvent after the light irradiation, etc. are required, which not only makes the manufacturing process complicated and expensive, but also uses a solvent etc. It has the problem of the environmental load by doing.
Japanese Laid-Open Patent Publication No. 6-210963

The inventor of the present application has been working on simplification of such dry transfer technology, and has developed, manufactured and sold a product “smart paper (trade name)” described in Non-Patent Document 1. This is because a mirror image is printed on a PET (polyethylene terephthalate) base material sheet that has been releasable on the surface by toner printing to form an image layer on the image layer. After applying acrylic glue and drying, the base sheet is brought into close contact with the transfer object and pressed, and when the base sheet is peeled off, only the image layer is adhered to the transfer object as a normal image and transferred. To be completed. The smart paper not only has a very simple process, but also does not use a solvent or the like, and therefore does not cause a problem of environmental load. In addition, since no water is used and no heat is applied during transfer, there are a wide range of materials that can be applied to metal, glass, synthetic resin, paper, wood, leather, fiber (cloth), and ceramics. Furthermore, since the image layer is transferred after being temporarily attached to a flexible substrate sheet, it can also be transferred to solid objects and curved surfaces that cannot be passed directly through the printer, reducing the cost of dry transfer, expanding the application range, This has the effect of simplifying and improving work efficiency.
Explanation of "smart paper" (applicant website page) URL: http://ing-global.net/smartpaper/index.html?id=movie

The present inventor further developed the smart paper, provided an image layer between the upper transfer film and the lower adhesive layer, and the transfer film has releasability from the image layer. A plurality of image transfer sheets characterized by having easy adhesion to the adhesive layer have been developed and patent applications have been filed (Japanese Patent Application Nos. 2016-106167 and 2016-123461: "Invention"). Since the image transfer sheets according to the inventions of the application do not need to form a glue layer by applying glue to a transfer object or remove glue protruding from the image after transfer, unlike smart paper, The work cost and work load can be reduced, and the finish can be homogenized. However, including the above-described invention of the present inventor, the conventional technique of transferring an image layer formed by toner printing with a glue layer has a problem to be solved when applied to a transfer object whose surface expands and contracts. .

Balloons have been popular as toys and ornaments for many years, but in recent years they have been increasingly used for events such as event ornaments, display ornaments, and promotional novelties. Accordingly, there is an increasing demand for so-called “arrange balloons” that print images of arbitrary designs, photographs, characters, and the like on the surface of the balloons. In particular, for applications such as promotional novelties and gifts, together with conventional rubber balloons and balloons made of resin films such as vinyl chloride, polyester, nylon, etc., the edges of sheets coated with these resin films by aluminum deposition are bonded together. Formed so-called “foil material” balloons (generally also called “mylar balloons”) are in widespread use. Since rubber balloons have a certain level of air permeability and are likely to wither over time, balloons that are floated with helium in particular are often made of a resin film with little air permeability. It has become.

Since rubber balloons have a very large material expansion ratio before and after expansion, silk printing using highly elastic ink is generally used for image printing. Silk printing is clear and can print an image that can follow the expansion of the balloon. However, since plate-making costs are required, there is an economic problem in the case of small lot printing, and it is not suitable for multicolor printing or photo printing. Also, when performing dry transfer printing using an image transfer sheet, the transfer operation must be performed with the rubber balloon inflated at least to some extent, which has problems in terms of labor and finishing. On the other hand, various printing methods can be applied to a balloon in which a resin film is bonded (hereinafter referred to as “bonded balloon”) in an original fabric state or a state before expansion. The sex issue is similar. In addition, some balloons made of resin film are integrally formed without bonding materials, but for the description of the present invention, they will be referred to as “bonded balloons” for the sake of convenience.

In addition to this, there is another method for manufacturing an arrangement balloon in a small lot, in which an image made of a cutting film is pasted on the balloon. However, the production and pasting of pasted images with a cutting film is not only labor-intensive and costly, but is basically applicable only to inflated balloons. When deflated, the balloon itself is deformed and the attached cutting film is easily peeled off.

Furthermore, since the balloon is a commodity that is required to be lightweight, helium is often injected and floated in the air. Therefore, when printing an image, the ink to be used must be lightweight. This is because if the weight of the ink is large, the balloon does not easily float, and the balloon in a floating state may be inclined due to the weight of the ink due to printing on one side. In addition, balloon materials such as rubber and resin films are extremely thin and vulnerable to heat, and in the case of foil materials, the surface may be damaged by moisture. Therefore, transfer printing such as silk printing, gravure printing, thermal transfer, and water transfer, in which the image layer is heavy, is not suitable for image printing on a balloon. On the other hand, toner printing is a printing method in which an image layer is formed with light toner particles without using a solvent, and thus can be said to be particularly suitable for image printing on a balloon made of vinyl chloride or a foil material.

FIG. 1 is a schematic diagram showing a general bonded balloon, and the balloon body B is formed by bonding the edges of two vinyl chloride sheets or aluminum vapor-deposited films cut into an arbitrary shape from a raw material by heat welding. Thus, the check valve V is provided, and the pump P is inserted into the check valve V, and air is injected to expand it. Such a balloon is not as elastic as a rubber balloon, and the surface thereof is smoother. Therefore, as shown in FIG. 2, in addition to printing a rich and detailed image by toner printing, it is possible to print a photograph.

Conventionally, in order to produce an arrangement balloon by adding an image to a bonding balloon by toner printing, the toner is printed on a raw material with a printing machine and then cut and bonded by thermal welding. It was. For this reason, not only is there a restriction on the size of an image that can be printed at once, but when a large arrangement balloon is manufactured, an image covering a wide area of the balloon surface may be divided into front and back materials and printed. However, at the time of completion, there is a problem in that a joining line generated by bonding by heat welding divides the image and a white line is generated in the image.

In addition, the bonded balloon has a smaller expansion and contraction of the material itself than the rubber balloon, but the surface expands into a curved surface by injecting air or gas. At this time, the image layer composed of toner particles adhered to the surface of the flat original fabric has a problem of causing cracks such as “penetration” generated in the glaze layer of the ceramic. Cracks not only make the printed image look dirty but also make the image layer easy to peel off, reducing the commercial value of the balloon, and particularly when printing a human face photo, there is a problem that the impression becomes worse due to cracks. It was.

Such cracks are unavoidable as long as the image layer is formed by toner printing as long as the expansion rate of the image layer cannot follow the expansion of the surface of the material due to the expansion of the balloon. Even with a technique for adhering an image layer to an object to be transferred with a glue layer as in the case of smart paper or the invention of the application, it was difficult to prevent cracking of the image layer.

The present invention has been devised to solve the above-described problems of the prior art, and image transfer for transferring an image of any design, photograph, character, etc. formed by toner printing on a balloon, particularly a bonded balloon. A method that suppresses deterioration in the quality of a transferred image caused by cracking of an image layer when a balloon is inflated, and prevents a bonding line of a balloon material from dividing the image and generating a white line in the image. It is an object to provide a transfer method.

In order to solve the above-mentioned problems, the invention described in claim 1 of the present invention is an image transfer method for transferring an image printed by a toner printer to the surface of a balloon, and applying a paste to the balloon surface. A first step of forming an adhesive layer, and a second step of pressing the image layer side of an image transfer sheet formed by toner printing on a substrate having releasability with respect to the image layer to the adhesive layer; It comprises a third step of crushing the surface of the substrate with a vibrator to crush the image layer and a fourth step of peeling the substrate from the image layer. That is, the image transfer method according to claim 1 is the image transfer method in which the above-described smart paper is applied to the balloon balloon before being expanded, and the image layer is crushed by rubbing the surface of the substrate with a vibrator. Three steps are added.

In view of the fact that cracks are inevitably generated in the image layer when the balloon is inflated, the inventor of the present application has come up with the idea of reversal not to prevent cracks but to make them inconspicuous even if cracks occur. In other words, cracks are conspicuous because the crack density is coarse, such as the penetration of a glaze layer in ceramics, and if the crack density is so small that it is difficult to distinguish visually, the quality of the visual image layer is improved. We focused on. Therefore, by adding a step of crushing the bond between the toner particles by applying vibration to the image layer pressure-transferred on the balloon surface by a vibrator, the density of cracks generated during expansion is reduced.

Next, an invention described in claim 2 of the present invention is an image transfer method for transferring an image printed by a toner printer to the surface of a balloon, and a substrate having releasability with respect to an image layer; A first step of pressing the adhesive layer side of the image transfer sheet consisting of an adhesive layer made of glue and an image layer provided between the substrate and the adhesive layer to the balloon surface; and rubbing the substrate surface with a vibrator And a second step of crushing the image layer and a third step of peeling the substrate from the image layer.

The image transfer method according to claim 2 is the image transfer method to which the image transfer sheet according to the invention of the present application filed by the inventor of the present application is applied. Similarly, the image layer is crushed by rubbing the substrate surface with a vibrator. The process is added. When the image transfer sheet having the configuration according to claim 2 is used when finally transferring the image to the transfer object, the step of applying the paste on the surface of the balloon in advance to form the glue layer can be omitted. In addition, as described above, the image layer is formed by toner printing because the image transfer to the balloon requires a reduction in weight. Therefore, the glue layer itself needs to be formed as thin and uniform as possible. In that respect, the thickness of the glue layer is made thinner and more uniform by applying an image transfer sheet with a glue layer formed on the back side of the image layer in advance than smart paper, which requires a manual glue application process. Since it is possible, it is more preferable.

In any of the image transfer methods according to

claims

1 and 2, the base material provided with the image layer may be pressure-bonded to the balloon through a cold laminator, that is, a laminator without heating. Conventionally, the image layer side of the base material is positioned and brought into contact with the surface of the balloon, and then the surface is rubbed from above with a valen for printing, etc., but the balloon covered with the base material is placed on the metal plate. By passing the cold laminator in a state where it is placed on the laminator, the laminator roller can be uniformly pressed. Thereby, the quality of the transferred image can be improved, and the productivity is also improved.

Next, the invention described in claim 3 of the present invention is the image transfer method to the balloon according to any one of

claims

1 or 2, wherein the image layer is a clear toner layer in order from the substrate side, It has a two-layer structure of a foil layer.

Clear toner is literally a transparent toner and is generally used to cause gloss on the printed surface. By making the image layer into a two-layer structure of a clear toner layer and a foil layer in order from the substrate side, the foil layer under the clear toner layer on the surface appears to be transmitted, so depending on the type of foil, gold, silver, copper, An image of a texture such as aluminum can be transferred to the balloon. As the foil, a ready-made foil film obtained by vapor-depositing a metal component on a transparent resin film can be used in place of the gold foil used in traditional crafts. The image layer having such a two-layer structure can be formed by the following method. That is, first, a reverse image is printed on a base material with a clear toner, and a laminator that can be heated at 110 ° C. to 140 ° C. with the base material is attached to the surface on which the foil film is deposited. Pass through. Since the clear toner is generally melted at around 125 ° C. to fuse the foil, when the foil film is peeled off from the substrate after cooling, the foil adheres to the shape of the image. On the other hand, the foil is not adhered to the portion outside the image without the clear toner, and is peeled off while remaining on the foil film. Through the above process, an image layer having a two-layer structure of a clear toner layer and a foil layer is formed.

By the way, it is possible to directly print an image with a metallic toner on a substrate without using a foil film, but the toner printer that can use the metallic toner is limited and the metallic toner itself is expensive. Also, the finish of the image of the foil film is much higher than that of the metallic toner.

The invention described in claim 4 of the present invention is the image transfer method to the balloon according to any one of

claims

1 or 2, wherein the image layer comprises a clear toner layer and a colored toner layer in order from the substrate side. And having a three-layer structure of a foil layer.

The image layer has a three-layer structure of a clear toner layer, a colored toner layer, and a foil layer in order from the base material side, so that the color tone of the foil made of a ready-made foil film can be variously changed. The colored toner layer can be provided by printing an image with a light-colored colored toner so that the colored toner layer overlaps the image formed by the clear toner layer, and the method of providing the foil layer is the same as that of the invention described in claim 3. Ready-made foil films are limited to single color such as gold, silver, copper, and aluminum, but it is possible to add gradations and patterns to metallic images by printing a colored toner layer. It becomes.

Next, an invention described in claim 5 of the present invention is the image transfer method to the balloon according to any one of claims 1 to 4, wherein the composition of the paste is made of vinyl acetate / acrylate. It is characterized by adding 10 to 35% of an aqueous acrylic emulsion to a polymer emulsion. The addition of the aqueous acrylic emulsion has the effect of improving the elasticity of the glue layer during curing without greatly reducing the adhesive strength of the glue.

As described above, it is desirable that the adhesive layer be as thin and uniform as possible. Further, the adhesive used has an adhesive force that prevents the image layer from being easily peeled off by fixing the image layer to the surface of the balloon. When the balloon is inflated after it has solidified over time, it is required to retain elasticity corresponding to the expansion of the surface. This is because even if the image layer has been finely crushed in advance by vibration of the vibrator, if the glue layer itself is cracked or unevenly stretched, the image layer may still be cracked at a density that is easily visible. Here, the elasticity of the glue layer can be realized by modifying the glue with additives, but the toner particles are made by mixing a plastic resin with a pigment, wax, a charge control material, etc. Oil-based additives cannot be used because they are soluble.

As a result of repeated trial and error on the composition of the paste by the present inventor, it is possible to obtain a suitable result by adding an aqueous acrylic emulsion to the vinyl acetate / acrylic acid ester copolymer emulsion at a weight ratio of 10 to 35%. found. Vinyl acetate / acrylic acid ester copolymer emulsion is a common component of so-called “emulsion glue” used for wallpaper with glue. On the other hand, the acrylic emulsion is emulsified using an acrylic resin as a dispersoid and water as a dispersion medium, and is a general component of a water-based undercoating paint used for adjusting the foundation of a building wall material. In the trial of the present inventor, it has been confirmed that when the weight ratio of the aqueous acrylic emulsion is less than about 10%, the adhesive layer has insufficient flexibility, and when it exceeds approximately 35%, the adhesive force of the adhesive layer is insufficient.

In addition, since the paste according to the present invention has appropriate elasticity, it can be repaired afterwards even when a cracked portion of the image layer is noticed when the balloon is inflated. That is, the balloon is once evacuated and deflated, and the image layer is crushed by applying vibration with a vibrator again from above on a place where the crack of the image is conspicuous. Thereby, a crack can be made inconspicuous and an image layer does not peel easily.

Finally, the invention described in claim 6 of the present invention is a balloon in which an image is transferred by the image transfer method of any one of claims 1 to 5.

The image transfer method according to the present invention has the following effects. That is,
(1) Since the image is adhered to the balloon surface by the glue layer, the durability of the image is higher than the method of printing the image directly on the balloon or the original fabric of the balloon with a toner printer, and the color is fine and clear. Image transfer is possible. Further, even when the balloon is deflated, the image is not easily peeled off.
(2) Since the image can be transferred so as to straddle the bonding line of the material peculiar to the bonded balloon, a white line that divides the image is not generated when the balloon is inflated. Therefore, large images can be transferred with high quality, and image transfer to a large balloon can be performed at low cost.
(3) Since the density of cracks generated in the image layer when the balloon is inflated can be reduced, the quality of the transferred image can be improved, and it is particularly suitable for transfer of photographs.
(4) Since the image layer has a two-layer structure of a clear toner layer and a foil layer in order from the substrate side, a high-quality metallic tone image can be transferred at a low cost. Furthermore, if the image layer has a three-layer structure of a clear toner layer, a colored toner layer, and a foil layer, gradation and a pattern can be easily added to a metallic tone image, and the expressiveness of the image transferred to the balloon can be improved.

(First embodiment)
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 3 is a schematic cross-sectional view showing the steps of an image transfer method to a balloon according to the first embodiment of the present invention using the smart paper described in claim 1. In the first step (1), the glue layer 13 is formed at a position where the image on the surface of the balloon B is transferred, in a range slightly larger than the image. The glue used for the glue layer 13 is obtained by adding 10 to 35% of an acrylic emulsion aqueous paint to a glue of vinyl acetate / acrylate copolymer emulsion. Also, the paste should be applied as thin and as uniform as possible. Next, in the second step (2), the smart paper 10 is adhered to the glue layer 13 and the image layer 12 is adhered by rubbing and pressing from the surface with valen or the like for printing, or through a cold laminator as described above. To do. The smart paper 10 is obtained by printing a mirror image on the back surface of the substrate 11 with a toner printer to form an image layer 12. Next, in the third step (3), the image layer 12 is crushed by applying vibration while uniformly rubbing the portion of the image layer 12 using the vibrator V. Finally, in the fourth step (4), the base material 11 of the smart paper 10 is slowly peeled off. At this time, since the base material 11 has releasability with respect to the image layer 12, the paste layer 13 in a portion protruding from the image layer 12 is removed from the surface of the balloon B while adhering to the base material 11. No. 12 remains and image transfer is completed.

(Second Embodiment)
FIG. 4 is a schematic cross-sectional view showing steps of an image transfer method to a balloon according to a second embodiment of the present invention using the image transfer sheet according to claim 2. In the first step (1), the image transfer sheet 20 is affixed at a position where the image on the surface of the balloon B is transferred. The image transfer sheet 20 includes a base material 21 having releasability with respect to an image layer, a paste layer 23 made of a paste, and an image layer 22 provided between the base material and the paste layer. As in the first embodiment, the glue used for the glue layer 23 is obtained by adding 10 to 35% by weight of an acrylic emulsion aqueous paint to the glue of the vinyl acetate / acrylate copolymer emulsion. After pasting, the image layer 22 is adhered to the surface of the balloon B by rubbing and pressing from the surface with valen for printing, or by passing through a cold laminator as described above, as in the first embodiment. In addition, the image transfer sheet 20 is a sheet with a paste (on which a reverse image is printed on a surface of a base material 21 by a toner printer and a paste layer is provided on the surface of a sheet-like separator (not shown)). The adhesive layer surface (not shown) can be applied, and then the separator can be peeled off to prepare in advance. Next, in the second step (2), as in the first embodiment, the image layer 22 is crushed by applying vibrations while equally rubbing the portion of the image layer 22 using the vibrator V. Finally, in the third step (3), similarly to the first embodiment, the base material 21 of the smart paper 10 is slowly peeled off. At this time, the base material 21 has releasability with respect to the image layer 22, while it has easy adhesiveness with respect to the paste, so that the portion of the paste layer 23 that protrudes from the image layer 22 adheres to the base material 21. While being removed from the surface of the balloon B, the image layer 22 remains and the image transfer is completed.

5 and 6 are comparative photographs showing the effect of improving the quality of the transferred image onto the balloon B by the image transfer method according to the second embodiment. The photographs 5A and 6A show the state of the image in which the second step of crushing the image layer 22 with a vibrator is omitted in image transfer using the image transfer sheet 20 and the balloon B after transfer is inflated. On the other hand, the photographs 5B and 6B show the state of the image when the second step is performed. As can be seen from the comparative photograph, the image when the second step is omitted is cracked with a coarse density in the shape of a ceramic intrusion on one side, and in particular, the crack can be easily seen from a distance of 1 m or more in the dark portion. It becomes a conspicuous state. On the other hand, the image when the second step is carried out has a very small crack density, and the quality is clearly improved.

FIG. 7 is a continuous view showing a manufacturing process of an image layer according to the fourth aspect of the present invention. (1) First, a desired image is printed as a reverse image on the surface of the base material by the toner printer P on the base material S with the clear toner to provide the clear toner layer c1. (2) Next, the color toner layer c2 is provided by printing the image with the color toner so as to overlap the clear toner layer c1. At this time, the color of the colored toner is not limited, but it is preferable to use a light color toner, and it may be printed as an image having a gradation or a pattern. (3) Next, a foil film M is placed on the image. The foil film M is formed by depositing a metal component on the back surface of the transparent resin film f to form a foil layer m, and various commercial products such as a gold foil tone, a silver foil tone, a copper foil tone, and an aluminum tone depending on the type of the metal component. Can be used. (5) Next, the printed substrate S covered with the foil film M is passed through a laminator L and heated by pressure. The temperature of the laminator L is preferably 110 ° C to 140 ° C. (6) By passing the laminator L, the foil film M is pressure-bonded onto the substrate S, and the clear toner layer c1 and the colored toner layer c2 are melted by heat so that the foil layer m is adhered only to the image portion. . (7) Finally, when the foil film M is peeled off from the substrate S, the foil layer m is transferred only to the image portion, and the portion outside the image is removed while remaining on the transparent resin film f. Through the above steps, an image layer having a three-layer structure of the clear toner layer c1, the colored toner layer c2, and the foil layer m is formed on the substrate S. Note that, by omitting the colored toner layer c <b> 2 in the above steps, an image layer having a two-layer structure according to claim 3 is formed.

FIG. 8 is a cross-sectional view showing a second step of the first embodiment in which an image transfer sheet having an image layer formed by the above step is pressure-bonded to a glue layer on the balloon surface. FIG. 9 is a cross-sectional view showing a second step of the second embodiment in which a glued image transfer sheet having an image layer formed by the above-described step is pressure-bonded to the balloon surface. In any transfer method, an image having a three-layer structure is adhered and transferred onto the balloon surface in the order of the foil layer m, the colored toner layer c2, and the clear toner layer c1 from the bottom. As a result, it is possible to freely change the color tone of the image of the metallic texture by the foil and add a gradation or a pattern depending on the color of the colored toner, thereby greatly expanding the expressive power of the transferred image. Further, since the surface of the transferred image is protected by the clear toner layer c1, the durability can be enhanced.

The specific configuration of the image transfer method according to the present invention has been described above. However, the present invention is not limited to the above embodiment, and can be improved or modified within the scope of the technical idea of the present invention. They belong to the technical scope of the present invention.

According to the present invention, an image that can be printed by a toner printer can be transferred to a balloon, particularly a balloon made of foil material, which has recently become popular, with high quality. In addition, by applying an image layer having a two-layer structure or a three-layer structure including a foil layer, it is possible to transfer an image having a rich metallic tone. There is an increasing demand for arrangement balloons for printing arbitrary original images in small lots, such as promotional novelties, event decorations, display decorations, party goods, souvenirs, etc. Has great applicability in that it can be realized at low cost and with high quality. In addition, the image transfer method according to the present invention is more suitable when the surface of the transfer object is softer than when the surface of the transfer object is hard. Therefore, a soft resin, to which image transfer by toner printing could not be applied conventionally due to the problem of image cracking The applicability is great in that it can be applied to products and the like.
