JP4005011B2 - Manufacturing method for body-attached decorative sheet - Google Patents

Description

The present invention relates to a method for producing a body-attached decorative body using a screen mold and a structure of a body-attached decorative body. Preferable examples to which the present invention is applied include nail art applied to nails or artificial nails, and body seals applied to skin.

It has been practiced to attach decorative bodies to the body such as nails and skin, but conventionally, decorative bodies are attached to objects by using transfer stickers and transfer sheets equipped with decorative bodies. I was doing it. Such a transfer seal or transfer sheet is manufactured as a printed matter printed by roll-to-roll.

However, the designs on these stickers are flat and have poor design because they do not give the texture, volume, and three-dimensionality of the designs, and are far from nail art that is actually drawn with a brush on nails or skin. is there. Moreover, when the sticking surface is three-dimensional or the shape of the sticking surface changes, the conventional seal lacks a feeling of fitting to nails, skin, and the like. In addition, when applying a sticker to the body such as nails and skin, it is necessary to have good water resistance and high fastness, because hands are washed, sweated and showered. Is done. There is a strong desire to provide a body-attached decorative body that satisfies such requirements, and the present applicant has achieved this by printing using a screen mold. Here, conventional techniques using a screen type include the following.

Japanese Patent Application Laid-Open No. 2001-1000063 relates to an adhesive seal capable of coloring, which discloses a method of creating an adhesive seal capable of coloring using screen printing. Specifically, an adhesive layer made of an ultraviolet curable adhesive is formed on a release paper by a printing technique such as screen printing, and a colored support layer made of an ultraviolet curable ink is formed thereon. Form an adhesive seal. The adhesive seal is affixed to the surface of a board made of wood, glass, metal or synthetic resin, or a box, container, figurine or the like made of those materials. However, ultraviolet curable ink has a low viscosity (about 120 poise), and such an ink cannot form a thick layer. Further, the ultraviolet curable adhesive has skin irritation, is not suitable for direct application to the body, and is inferior in water resistance. The ultraviolet curable adhesive does not cure unless it is irradiated with ultraviolet rays, so that the adhesive is not cured at the time of printing and does not cause problems during screen printing.

Japanese Patent Application Laid-Open No. 2003-183985 discloses a method for creating a transfer sheet using screen printing. First, a hot melt is silk screen printed on a support film. After the hot melt adhesive is dried, the foamed resin is silk screen printed thereon and dried. The transfer sheet is transferred to fabric, paper, vinyl, and leather by heating with a heat press. However, since the hot melt adhesive exhibits adhesiveness when heated to 100 ° C. or higher, the hot melt adhesive cannot be applied to the body. Hot melt adhesives are conventionally used for silk screen printing, and there is no difficulty in forming a hot melt adhesive layer by silk screen. Furthermore, since the hot melt adhesive does not have an effective adhesive property at normal temperature, the hot melt layer does not become sticky at the normal temperature due to the stickiness of the hot melt layer. Moreover, with the passage of time, peeling is likely to occur between the hot melt adhesive layer and the support film.

The pressure-sensitive adhesive means a material that can be attached to an adherend and peeled off at room temperature (room temperature) only by pressing with a pressure of about a finger pressure. Formation of the pressure-sensitive adhesive layer using the pressure-sensitive adhesive is usually performed by a roll coater or spray coating, and the pressure-sensitive adhesive layer is not formed using a screen plate. Because the adhesive (except UV curable type) has a short pot life (pot life), the adhesive is dried and solidified on the surface of the screen plate, or the adhesive on the screen plate is clogged with the adhesive. Because it ends up. However, as a result of intensive studies by the present applicant, it has been found that an adhesive layer can be formed using a screen plate even with an adhesive. In the present invention, the term “natural dry pressure-sensitive adhesive” means a pressure-sensitive adhesive whose drying proceeds at room temperature (normal temperature). The naturally-drying pressure-sensitive adhesive does not include an ultraviolet curable pressure-sensitive adhesive or a hot melt adhesive. In the present specification, the air-drying pressure-sensitive adhesive may be subjected to heat treatment or hot air treatment when drying the pressure-sensitive adhesive, as long as drying proceeds at room temperature and the viscosity of the pressure-sensitive adhesive increases. Also included are advantageous adhesives, or adhesives that begin to cure upon mixing of the two liquids. The pressure-sensitive adhesive preferably includes an acrylic pressure-sensitive adhesive, a silicone-based pressure-sensitive adhesive, a urethane-based pressure-sensitive adhesive, a rubber-based pressure-sensitive adhesive, and a vinyl ether-based pressure-sensitive adhesive. When the main body layer or the buffer layer is made of a printing agent containing a silicone resin, it is advantageous to employ a silicone adhesive as the adhesive layer. The pressure-sensitive adhesive includes a two-component pressure-sensitive adhesive, a one-component pressure-sensitive adhesive, a room temperature-drying pressure-sensitive adhesive, a heat-drying pressure-sensitive adhesive, a room temperature / heat-drying pressure-sensitive adhesive, a two-component room temperature-curing pressure-sensitive adhesive, and the like. The pressure-sensitive adhesive employed in the present invention is preferably a low skin irritation pressure-sensitive adhesive. The low skin irritation adhesive is an adhesive having low skin irritation, and the UV curable adhesive is not included in the low skin irritation adhesive because it has high skin irritation. Skin irritation includes physical irritation (stress on the skin at the time of peeling, stress on the skin during application), and chemical irritation (chemical irritation by components, etc.). Whether the skin irritation is low is determined by a skin irritation test (for example, a patch test). The low skin irritation adhesive can be used as a medical adhesive. Medical adhesives include acrylic adhesives, rubber adhesives, silicone adhesives, vinyl ether adhesives, and urethane adhesives. The screen plate mesh for the adhesive layer is preferably 80 or less, more preferably 50 or less. In order to allow the adhesive to pass through the watermark portion, the coarser the mesh of the watermark portion, the easier it is to remove. The thickness of the adhesive layer is preferably 80 μm to 200 μm. In general, it is considered that the adhesive strength increases as the thickness of the adhesive layer increases, the adhesive strength is insufficient when the film thickness is too thin, and there is a possibility that stress is applied to the skin when the film thickness is too thick. A release coating made of a silicone release agent or the like is applied to at least the screen portion of the watermark portion of the adhesive layer screen plate. More preferably, the release coating is applied to the entire surface of the screen ridge, thereby improving the working efficiency at the time of washing the plate.

The aqueous stretchable resin contained in the printing agent for the main body layer or the buffer layer is a urethane resin, an acrylic resin, a silicone resin (silicone rubber), an acrylic urethane, or any other mixed resin. The printing agent may contain a thickener, a drying retarder and the like as an auxiliary agent.

The mesh of the screen plate for the buffer layer is 120 or less, preferably 80 or less, more preferably 50 or less (for example, 36 to 50). The printing agent for the buffer layer has a viscosity of 50000 centipoise or less at room temperature.

The evaporation drying treatment of the main body layer preferably includes a first heat treatment step (preliminary drying treatment) and a second heat treatment step at a higher temperature than the first heat treatment step. The first heat treatment step (preliminary drying treatment) is preferably at a temperature of 50 ° C to 120 ° C, and the second heat treatment step is preferably a temperature of 120 ° C to 200 ° C.

The step of forming the decorative body may include a step of forming a negative ion generation layer. The negative ion generation layer is formed by printing a printing agent mixed with a negative ion generation substance using a screen plate. A negative ion generation layer may be formed by mixing a negative ion generation material in at least one of the printing agent of the adhesive layer, buffer layer, main body layer, and top layer, or printing in which a negative ion generation material is mixed. You may form a negative ion production | generation layer separately from an adhesion layer, this buffer layer, this main body layer, this main body layer, and this top layer using an agent.

The main body layer has a larger area than the adhesive layer, and the main body layer is mixed with a foaming agent, so that the part of the main body layer that protrudes from the adhesive layer is removed by the evaporation drying process with heat treatment. It may be deformed so as to peel from the release surface to give a three-dimensional effect.

ADVANTAGE OF THE INVENTION According to this invention, the sheet | seat with a sticking decoration body which is thick, has a three-dimensional effect, and is excellent in design can be provided. When the film thickness of the main body layer is 80 μm or more, a stereoscopic effect appears in the decorative body visually. The water-based stretchable resin employed in the present invention can form a thick layer and has elasticity, water resistance and fastness after drying and effect.

ADVANTAGE OF THE INVENTION According to this invention, the sheet | seat with a sticking decoration body advantageous to sticking to a body can be provided. That is, it is possible to form a decorative body having no adverse effects on the body and having water resistance and fastness. In addition, since the main body layer is formed of a stretchable resin, it can cope with non-planar (curved surface) nails and skin (the curved surface changes in the skin).

In the case where the buffer layer is formed on the adhesive layer, the decorative body can be satisfactorily formed even when the screen plate is used and laminated on the adhesive layer provided on the release surface. Excellent workability.

In a decorative body having a negative ion generation layer, since the decorative body is attached to the body, a negative ion effect (stress reduction, healing, etc.) is given to the wearer.

The textile printing using the silk screen which is the premise of the present invention will be described. First, the screen type | mold for forming the shape and design of the decoration body to stick is prepared. The screen mold is made of a wooden or metal (for example, aluminum) square frame with a synthetic fiber such as polyester, nylon, or tetron, or a silk screen made of silk or stainless steel. A watermark is formed on the screen with the emulsion coated in a predetermined shape. The silk screen printing method puts ink on the surface part in the frame of the screen mold, presses and moves the squeegee, and the ink passes through the watermark part formed on the surface part, and the surface to be printed under the plate To be printed.

The watermark portion is formed from a large number of wrinkles, and whether printing is performed satisfactorily is affected by properties such as the viscosity of the ink used, printing pressure by a squeegee, and mesh (weave density). The mesh is the mesh density of the cocoon and is the number of yarns woven between 1 inch. If the viscosity of the ink is high, it is difficult for the ink to pass through the watermark portion, and a higher printing pressure is required. If the viscosity of the ink is low, the ink can easily pass through the watermark portion, and printing can be performed with a smaller printing pressure. Further, when the viscosity of the ink is low, the ink spreads horizontally on the surface to be printed, and it becomes difficult to form a thick film. In the case of using a low-viscosity ink, generally, a high-mesh screen plate is used (printing is beautiful). In the silk screen printing method, in principle, a screen type of one color and one type is created. Also in the present invention, when a pattern is composed of a plurality of colors, a plurality of patterns for forming a pattern in advance are used. It is necessary to prepare a screen type.

First, a basic configuration for forming a decorative body using a silk screen will be described. 1 and 2, the buffer layer described later is not provided, but of course, a step of providing a buffer layer may be included. The decorative body 1 shown in FIG. 1 has a planar star-like overall shape, and is formed on the planar-view star-shaped adhesive layer 3 and the adhesive layer 3 formed on the upper surface of the release sheet 2. A star-shaped first main body layer 4 and a smaller star-shaped second main body layer 5 formed on the first main body layer 4 are shown. Is formed. In order to form such a decorative body on the release sheet, three screen molds S1, S2, and S3 are prepared. The screen mold S1 is an adhesive layer forming screen mold having a watermark M1 corresponding to the overall shape of a star-shaped decorative body. The screen mold S2 is a main body layer forming screen mold having a watermark portion M2 corresponding to the shape of the first main body layer 4 of the star-shaped decorative body. The screen mold S3 is a main body layer forming screen mold having a watermark portion M3 corresponding to the shape of the second main body layer 5 of the star-shaped decorative body. The watermark section is composed of a cocoon mesh (not shown).

The release sheet 1 is detachably fixed on the base 6, the screen mold S1 is positioned on the sheet 1, the adhesive is put in the frame of the screen mold S1, and the adhesive is printed with a squeegee (not shown). Then, the adhesive layer 3 is formed on the sheet 1 (a). Next, the screen mold S1 is removed, the screen mold S2 (the shape of the watermark is the same as S1) is positioned at a predetermined position on the sheet 2, and the body layer forming printing agent is placed in the frame of the screen mold S2. The body layer printing agent is printed with a squeegee (not shown) to form the first body layer 4 on the adhesive layer 3 (b). The screen mold S2 is removed, the screen mold S3 is positioned at a predetermined position on the sheet 2, the main body layer forming printing agent is placed in the frame of the screen mold S3, and the main body layer printing agent is printed with a squeegee (not shown). Then, the second main body layer 5 is formed on the first main body layer 4 (c). In this way, the three-dimensional decorative body 1 in which the adhesive layer 3 and the large and small main body layers 4 and 5 are laminated is formed on the sheet 2 by printing using the screen molds S1, S2, and S3 in order. . The colors of the printing agents used for printing by the screen molds S2 and S3 may be the same color or different colors, and are appropriately selected so as to correspond to a desired decorative design.

FIG. 2 shows a decorative body having another pattern / shape. A screen mold S10 having a watermark portion M10 having a shape corresponding to substantially the entire shape of the flower-shaped decorative body 1, a screen mold S20 having a watermark portion M20 having a shape corresponding to the shape of the circular central portion 40, and the periphery of the central portion 40 Three screen molds, that is, a screen mold S30 having a watermark portion M30 corresponding to the shape of a plurality of circular peripheral portions 50 provided in FIG. The release sheet 2 is detachably fixed on the base 6, the screen mold S10 is positioned on the sheet 2, and an adhesive is printed to form the adhesive layer 3 on the sheet 2 (a). Next, the screen mold S10 is removed, the screen mold S20 is positioned at a predetermined position on the sheet 2, and the central portion 40 is formed on the adhesive layer 3 (b). The screen mold S20 is removed, the screen mold S30 is positioned at a predetermined position on the sheet 2, and five peripheral portions 50 are formed on the adhesive layer 3 (c). The screen molds S20 and S30 have different thicknesses, so that the central portion 40 and the peripheral portion 50 to be printed have different thicknesses. Further, a foaming agent is mixed in the printing agent for the main body layer constituting the central portion 40 and the peripheral portion 50, and after the main body layer is formed, the main body layer is foamed by performing a heat treatment ( d). In this way, printing is performed sequentially using the screen molds S10, S20, and S30, and further heat treatment is performed, whereby the three-dimensional decorative body 1 including the adhesive layer 3, the central portion 40, and the peripheral portion 50 is formed. The The colors of the printing agents used for printing by the screen molds S20 and S30 may be the same color or different from each other, and are appropriately selected so as to correspond to a desired decorative design. In FIG. 2, when the main body layers 40 and 50 are multicolored, it is necessary to prepare a multicolor printing agent mixed with a foaming agent. On the other hand, the main body layer is formed on the first main body layer and the first main body layer made of a transparent resin mixed with a foaming agent, and does not include the foaming agent, and the second is mixed with a predetermined pigment. You may comprise from a main body layer. Referring to FIG. 2, using a mold corresponding to the overall shape of the decorative body, a transparent resin mixed with a foaming agent is printed on the adhesive layer to form the first main body layer. On the first body layer, a second body layer is formed by printing a resin mixed with individual pigments corresponding to the design of the decorative body. And you may comprise a three-dimensional decoration body by expanding a 1st main body layer by heat processing. By doing this, it is sufficient to prepare one type of printing agent mixed with a foaming agent, and there is no influence even when the foaming agent-containing resin is discolored during foaming. 2 differs from that shown in FIG. 1 in that the adhesive layer and the main body layer have the same overall shape in FIG. 1, whereas in FIG. The adhesive layer is slightly larger, and the main body layer is integrated through the adhesive layer. Since the adhesive layer is made of a transparent resin, there is no problem in design even if the adhesive layer protrudes from the main body layer.

FIG. 3 is a diagram illustrating a screen mold (an example corresponding to the overall shape of the decorative body). The screen mold S is a rectangular frame 7 and a surface portion 8 stretched in the frame 7. The surface portion 8 is formed by applying an emulsion over substantially the entire surface of the screen wrinkle to block the space of the screen wrinkle and removing a predetermined portion of the film to expose the air gap of the screen wrinkle. And a plurality of watermark portions M. In the present invention, preferably, the entire surface of the emulsion film is coated with a urethane resin. Preferably, at least the watermark portion M is coated with a lubricant, and more preferably, the entire surface portion 8 is coated with a lubricant. In a preferred example, the decorative body targeted by the present invention is affixed to an artificial nail or a nail, and when the decorative body is relatively small as described above, as illustrated in FIG. The screen type is formed with a watermark portion M having a large number of the same type and / or different shape (illustrated in the case of the same shape, not shown in the figure). Only the watermark is shown.)

In the screen mold S, an alignment protrusion 9 is formed to extend, and at the time of printing, the protrusion 9 is brought into contact with a point 10 (indicated by a dotted line) provided on the base side, whereby the screen mold S Perform positioning. That is, the respective screen molds are positioned with respect to the release sheet fixed on the base (projection piece 9 on the screen mold side and point 10 on the base side) and printing is performed, so that each layer does not shift. The decorative body can be formed by being laminated. At the time of printing, the release sheet is always fixed on the base, and each screen mold is positioned and set with respect to the fixed release sheet. Then, by using a screen mold having a mold corresponding to a large number of decorative bodies as shown in FIG. 3, one sheet having a large number of decorative bodies can be formed as shown in FIG. good. In FIG. 4, it has the sticking decoration body which consists of the release sheet 2 and the some decoration body 1 (it consists of the adhesion layer 2, the 1st main body layer 4, and the 2nd main body layer 5) provided on the release surface. A sheet is described.

A first embodiment of the present invention will be described. Produce multiple screen molds according to the design of nails, artificial nails or decorative objects to be attached to the skin. The screen mold includes a screen mold for forming an adhesive layer, a screen mold for forming a buffer layer, one or a plurality of screen molds for forming a main body layer, and a screen mold for forming a top layer.

First, an adhesive is applied to the upper surface of the base 6. A release sheet 3 such as release PET or release paper is detachably fixed on the base 6 via the adhesive. A release agent (for example, silicone) is applied to the surface of the release sheet 3. Further, since an adhesive is applied to the upper surface of the base 6, the release sheet 2 is constituted by a double-sided release sheet so that the release sheet 2 is detachably fixed on the base 6. It has become.

The pressure-sensitive adhesive layer 3 is formed by printing the pressure-sensitive adhesive on the release sheet 2 detachably fixed on the base using a pressure-sensitive adhesive layer forming screen mold having a watermark corresponding to the overall shape of the decorative body. The pressure-sensitive adhesive forming the pressure-sensitive adhesive layer 3 is a two-component curable acrylic pressure-sensitive adhesive (curing agent: isocyanate, viscosity adjustment: ethyl acetate). The two-component curable acrylic pressure-sensitive adhesive here is a room temperature curable type (the curing can be accelerated by heating). Here, there is no technical idea of printing a room temperature drying or room temperature curable adhesive using a screen plate. Room temperature drying type or room temperature curing type adhesives are dried and cured naturally during printing, so the adhesive begins to cure immediately after the adhesive is put on the surface of the screen plate. Viscosity becomes too high and printing cannot be performed immediately. That is, the pot life as a printing agent is short. As drying and curing of the printing agent for the adhesive layer proceeds, the state of sticky and sticking, which is a characteristic of the adhesive, starts immediately. Therefore, it is very difficult to adjust the printing pressure, and the pressure-sensitive adhesive blocks the watermark portion of the screen ridge. Therefore, it was considered technically impossible to apply through a screen plate. Actually, the current processing method is still transferred to the transfer object, and the punching die is used as a punching die.

Therefore, we considered the following. First, it was adopted that a release sheet was attached to the base and attached and printed through a screen mold to prevent the sheet from shifting during printing due to adhesion of the adhesive layer. Next, an oil-based aqueous emulsion was used as a screen mold for forming an adhesive layer, and the surface portion was constituted, and a urethane resin was applied as a coating agent on both surfaces of the surface portion. A screen plate is produced that prevents the intrusion of ethyl acetate, which is the source of the adhesive layer between the aluminum frame and the heel. The coating of the urethane resin also has an effect of reinforcing the screen-type surface portion (particularly, the watermark portion), and prevents the plate from being damaged. Specifically, at the time of printing, the lower layer is a release sheet having no flexibility like a cloth, and a stronger force is applied to the plate at the time of printing, so that reinforcement of the plate is advantageous. At the time of washing the plate, first, it is advantageous to increase the washing frequency of the plate, and it is necessary to wash with a stronger force in order to remove the adhesive. The plate having a urethane coating on the surface portion is advantageous not only for the pressure-sensitive adhesive layer-forming plate but also for the buffer layer-forming plate, the main body layer-forming plate, and the top layer-forming plate.

Although it is advantageous to always replenish with a new pressure-sensitive adhesive in order to delay the start of curing of the pressure-sensitive adhesive, it is not constant because the curing speed varies depending on the temperature and humidity in the atmosphere. Therefore, even if the adhesive is printed through the screen plate by coating the front and back of the screen plate with a silicone lubricant (solution) so that the adhesive does not get entangled in the screen plate of the screen plate, it will stick to the screen plate. We have created a state that does not involve the watermark and watermark. The lubricant is preferably applied to the entire face of the plate. By doing so, the plate can be washed well.

The thickness of the adhesive layer is preferably 50 μm to 400 μm, and more preferably 100 μm to 200 μm. When the film of the adhesive layer is too thin, a problem occurs in the adhesive force. Further, since the pressure-sensitive adhesive is dried and cured on the surface portion of the plate due to its pot life, it becomes difficult to form a thick film due to poor removal from the watermark portion provided on the surface portion of the plate. Moreover, when the adhesive force of an adhesion layer is too strong, when peeling from a body, there exists a possibility of giving stress to skin etc. As the pressure-sensitive adhesive, in addition to the acrylic pressure-sensitive adhesive, for example, a urethane-based pressure-sensitive adhesive or a silicone-based pressure-sensitive adhesive can be employed. Preferably, the pressure-sensitive adhesive is a medical pressure-sensitive adhesive that satisfies the criteria of a patch test (skin test).

The screen-type screen cage for forming the adhesive layer is made of polyester or nylon. The mesh (weave density) of the plate is 120 or less, preferably 80 or less, more preferably 50 or less, for example, 36 to 50. The thickness of the ridge is preferably 50 denier when the mesh density is 50 or less, and 20 denier when the mesh density is 50 to 120. The emulsion thickness of the plate is preferably 150 μm to 250 μm.

The pressure-sensitive adhesive is formed by printing once or twice with a squeegee, and preferably forms a pressure-sensitive adhesive layer having a thickness of 150 μm to 200 μm. The adhesive layer is dried and cured by natural drying, hot air drying, or heat drying. Examples include a drying process using a far-red heater for 1 minute to 10 minutes, or a buffering process using a dryer and natural drying for 2 minutes to 30 minutes. The drying time may vary depending on the thickness of the adhesive layer and indoor conditions (temperature, humidity, etc.).

As the second layer, using a screen mold corresponding to the overall shape of the decorative body (that is, having a watermark portion having the same shape as that of the adhesive layer), the buffer layer printing agent is printed on the adhesive layer to form the adhesive layer. A buffer layer K is formed so as to cover the surface. The area and shape of the buffer layer K may be substantially the same as the area and shape of the adhesive layer, and may not be completely the same. For example, when the printing agent for the buffer layer is formed from a transparent resin, there is no problem even if the buffer layer K slightly protrudes from the adhesive layer.

The purpose of providing the buffer layer K will be described. Printing and laminating a resin using a screen mold on the adhesive layer on the release sheet has the following problems. After the adhesive is printed to form the adhesive layer, the adhesive layer is naturally dried and cured. Then, the surface of the pressure-sensitive adhesive layer exhibits stickiness (the pressure-sensitive adhesive is inherently cured and stickiness comes out). On the other hand, since the back surface of the pressure-sensitive adhesive layer directly adheres to the release surface of the release sheet, the pressure-sensitive adhesive layer easily peels off from the release sheet when a force in the direction in which the surface of the pressure-sensitive adhesive layer adheres to and lifts up acts. Become. Here, when the main body layer is printed directly on the adhesive layer, the resin for the main body layer on the screen mold begins to dry with the passage of time, and there is a phenomenon that the watermark cannot be removed unless the printing pressure is increased. When the printing pressure is increased, a phenomenon occurs in which the screen-type wrinkles press the adhesive layer, and pressure is applied, causing the adhesive layer to adhere to the back of the plate. In some cases, the adhesive layer is peeled off from the release sheet. End up. Although it is possible to prevent adhesion by changing the resin on the screen mold in a short time or adjusting the printing pressure, it is extremely advantageous to form a buffer layer in consideration of work efficiency. It is.

In order to solve this, a screen type corresponding to the overall shape of the decorative body (that is, having a watermark portion that can form a layer having the same size and shape as the adhesive layer corresponding to the overall shape of the decorative body) The screen layer is used to form a buffer layer K that covers the entire surface of the adhesive layer. The resin forming the buffer layer K has a viscosity equal to or lower than that of the resin of the main body layer at the time of printing, and preferably has a viscosity lower than that of the resin of the main body layer. The low viscosity of the printing agent means that printing with a lower printing pressure is possible, and printing can be performed without applying pressure to the adhesive layer. Since printing can be performed without applying pressure to the adhesive layer, the adhesive layer is prevented from adhering to the screen mold. The buffer layer K covers the entire surface of the adhesive layer, so that the main body layer is not directly printed on the adhesive layer.

By providing the buffer layer, the thickness of the decorative body is increased correspondingly, and the interlayer adhesion between the buffer layer and the main body layer is good. Therefore, the buffer layer also has an effect of increasing the strength of the decorative body. In addition, the printing agent contains auxiliary agents such as water and a thickener as a solvent, and the viscosity adjustment of the printing agent is often adjusted by the amount of the thickener, and the amount of the thickener is large. If the viscosity is high and the amount of the thickener is small, the viscosity becomes low. If the amount of the thickener is small, the concentration of the urethane resin increases and the hardness increases when the printing agent is dried to evaporate water.

The printing agent for the buffer layer contains an aqueous urethane resin, a drying retarder, and a thickener, and the viscosity at normal temperature is 50000 cps or less, preferably 10,000 cps or more, and more preferably 20000 cps to 50000 cps. When the viscosity of the printing agent is higher than 50000 cps, the pressure during printing of the printing agent is increased and the plate and the adhesive layer may adhere. If the viscosity of the printing agent is less than 10,000 cps, it is likely to be repelled on the adhesive layer 3. In addition, when the buffer layer is provided with an effect of reinforcing the decorative body, it is desirable that the viscosity of the printing agent is 20000 cps or more so that the buffer layer has a thickness. Instead of the urethane resin, an acrylic resin or a urethane acrylic mixed resin can be used. The thickness of the buffer layer is 50 μ to 200 μ, preferably 50 μ to 100 μ.

The screen-type bag for forming the buffer layer is made of polyester or nylon. The mesh (woven density) is 120 or less, preferably 80 or less, more preferably 50 or less (for example, 36 to 50). The thickness of the ridge is preferably 50 denier when the mesh density is 50 or less, and 20 denier when the mesh density is 50 to 120. The emulsion thickness of the plate is 50 μm to 250 μm, preferably 50 μm to 100 μm.

The buffer layer is formed by printing once or twice using a screen plate. After printing the buffer layer, the buffer layer is dried. Drying is natural drying, hot air drying, or heat drying. The printing agent for forming the buffer layer is transparent in a preferred example, but may be colored.

Next, the body layers 4 and 5 are formed by printing the body layer printing agent on the buffer layer K by using the body layer forming screen mold corresponding to each part of the decorative body. A multicolor printing agent is prepared by mixing a pigment into the main body layer printing agent. The main body layer is printed in multiple colors according to the number of colors of the pattern, and is usually formed using a plurality of screen molds. Further, a three-dimensional pattern may be expressed by mixing a foaming agent or the like into the main body layer printing agent and foaming the foaming agent by applying heat. Although two main body layers 4 and 5 are illustrated in FIG. 5, the number of main body layers is one or more and is not limited to two.

The printing agent for the main body layer contains an aqueous urethane resin, a drying retarder, and a thickener, and the viscosity at room temperature is 30000 cps to 200000 cps, preferably 50000 cps to 150,000 cps. When the viscosity of the printing agent is smaller than 30000 cps, it is difficult to form a film having a desired thickness. When the viscosity of the printing agent is larger than 200000 cps, the printing agent is clogged in the watermark portion and does not pass through the watermark portion. If the viscosity of the printing agent is less than 50000 cps, multiple times of printing are required to form a film having a desired thickness, and the workability is inferior. If the viscosity of the printing agent is more than 150,000 cps, the printing agent has a good watermark. It may not pass through and lacks practicality. Instead of the urethane resin, an acrylic resin or a urethane acrylic mixed resin can be used. The thickness of the main body layer is 80 μm or more, and preferably 80 μm to 600 μm.

By mixing the foaming agent in the printing agent of the main body layer, the main body layer can be raised by a subsequent heat treatment. When the foaming agent is mixed, the thickness of the main body layer of the final product (after foaming) is 100 μm to 5 cm, preferably 100 μm to 1 cm.

The screen-type screen cage for forming the main body layer is made of polyester or nylon. The mesh (woven density) is 150 μm or less, preferably 24 μm to 150 μm, and more preferably 36 to 120. The thickness of the ridge is preferably 50 denier when the mesh density is 50 or less, and 20 denier when the mesh density is 50 to 150. The emulsion thickness of the plate is 50 μm to 600 μm, preferably 50 μm to 400 μm.

A top layer (protective layer) T is formed by printing a top layer printing agent using a screen mold corresponding to the overall shape of the decorative body. The printing agent for the top layer preferably contains an aqueous stretch resin having solvent resistance (particularly acetone used for nail polish) and / or water resistance after drying and curing. The printing agent used for the top layer T is preferably transparent. Further, a decorative piece of lame piece may be mixed into the top layer T. The top layer T is not necessarily essential when used as a material to be attached to the body instead of the nail. Therefore, after the step of forming the main body layer, the step of printing the solvent-resistant stretchable resin using a screen mold selected corresponding to the overall shape of the decorative body is optional.

The printing agent for the top layer T includes an aqueous urethane resin, a drying retarder, and a thickener, and the viscosity at normal temperature is preferably 30000 cps to 200000 cps, and more preferably 50000 cps to 150,000 cps. Instead of the urethane resin, an acrylic resin or a urethane acrylic mixed resin can be used. The thickness of the top layer is preferably 50 μm to 200 μm.

The top layer forming screen type ridge is made of polyester or nylon. The mesh density (weave density) is 150 μm or less, preferably 36 μm to 150 μm, and more preferably 36 to 100. The thickness of the ridge is preferably 50 denier when the mesh density is 50 or less, and 20 denier when the mesh density is 50 to 150. The emulsion thickness of the plate is from 50 μm to 200 μm.

The evaporative drying process of the decorative body (particularly the main body layer) will be described. By drying and curing the water-based stretchable resin constituting the decorative body, the decorative body is given elasticity, water resistance, and fastness. After the printing, the release sheet on which the decorative body is formed is removed from the base. The release sheet has a release surface on both sides, and is attached to the adhesive on the base via the release surface on the back, and can be easily peeled off from the base.

First, a first drying process (preliminary drying) is performed. The temperature and treatment time of the preliminary drying vary depending on the season and the outside temperature, but in a preferable range, drying is performed at a temperature range of 50 ° C. to 120 ° C. (more preferably 70 ° C. to 100 ° C.) for 5 minutes to 30 minutes. Perform processing.

Next, a second drying process is performed. The temperature of the second drying treatment is preferably in the range of 120 ° C. to 200 ° C. (more preferably 120 ° C. to 150 ° C.), and the treatment time is 1 minute to 5 minutes. In the preferred example, the drying processing means is a far-red heater, but the means is not limited to this. When a foaming agent is used for the main body layer, it is desirable to perform the second drying process a plurality of times or extend the processing time, although it depends on the thickness of the main body layer.

In particular, when a foaming agent is mixed in the main body layer, the foamed surface tends to become uneven if the main body layer retains moisture, and therefore, two-stage drying of the first drying process and the second drying process is preferable. . The evaporation drying process is not necessarily limited to one performed in two stages. For example, the decorative body can be dried by adjusting the time between 50 ° C. and 200 ° C. according to the selected temperature. The body layer can be naturally dried if it takes a long time, but it takes a long time to dry, which is not practical. Furthermore, the moisture contained in the printing agent evaporates even when it is naturally dried at room temperature, but some auxiliary agents (for example, drying retarders) contained in the printing agent do not evaporate due to natural drying. The evaporative drying process advantageously includes a heat treatment higher than room temperature.

Thus, the sheet | seat which has the decoration body comprised from the adhesion layer 3, the buffer layer K, the main body layers 4 and 5, and the protective layer T so that attachment or detachment is possible is formed. The decorative body can be peeled off from the release sheet 2 and applied to an artificial nail or a real nail and enjoyed as a fashion. Since the decorative body is attached on the release sheet via a pressure-sensitive adhesive (adhesive at room temperature), it can be put on the distribution process as a sheet having a decorative body, and stored and sold as a sheet. Can do.

Example 2 relates to a body-attached decorative body that generates negative ions. The process of forming the decorative body is substantially the process described in Example 1, and relates to the base, release sheet, adhesive layer, buffer layer, body layer, top layer, etc. described in Example 1. Since a specific configuration can be used for the description of the second embodiment, details are omitted. As shown in FIG. 6, the decorative sheet is formed on the release sheet 2, the adhesive layer 3 formed on the release sheet 2, the buffer layer K formed on the adhesive layer 3, and the buffer layer K. The negative ion generation layer I, the main body layer 4 formed on the negative ion generation layer I, and the top layer T formed on the main body layer 4, and the decorative body includes the adhesive layer 3 and the buffer layer K And a negative ion generation layer I, a main body layer 4 and a top layer T.

A method for producing such a decorative sheet will be described. First, an adhesive is applied to the surface of the base 6. Next, the double-sided release sheet 2 is detachably fixed on the adhesive surface of the base 6. Next, the self-curing and drying type pressure-sensitive adhesive is printed on the release sheet 2 to form the pressure-sensitive adhesive layer 3. Next, a buffer layer printing agent is printed on the adhesive layer 3 to form the buffer layer K. Next, a printing agent mixed with a substance that generates negative ions is printed on the buffer layer K to form the negative ion generation layer I. Next, a main body layer printing agent is printed on the negative ion generation layer I to form the main body layer 4. A top layer T is formed on the main body layer 4.

The negative ion generation layer is attached so as to cover the upper surface of the buffer layer K, for example, by printing using a plate having a watermark having a shape corresponding to the overall shape of the decorative body. The negative ion generation layer does not necessarily have a shape corresponding to the overall shape of the decorative body. The printing agent for the negative ion generation layer is similar to the printing agent for the main body layer, the buffer layer, or the top layer, and is a printing agent containing an aqueous stretchable resin (for example, a transparent aqueous urethane resin). is there. The negative ion generating substance is a powder having such a size that it can pass through the stencil of the screen plate, and has a diameter of, for example, 500 μm or less. Depending on the selected soot clean mesh, an appropriately sized powder is selected, and the larger the mesh, the smaller the selected powder size. The negative ion generating substance is mixed in a proportion of 0.5 to 10% by weight with respect to the printing agent, for example.

The negative ion product mixed in the printing agent is a fine powder such as ore that generates negative ions, such as rare earth ore, tourmaline, igneous rock, barley stone, kiyoishi, amber, black Carbon, garnet, coral stone, thoron, diatomaceous earth, turkey, monazite, bustness stone davidite, blannelite, senurite, nymphite, linca uranium, carnotite, tsuyamunite, matachamunite, francesvilleite, tallstone, Coffin stones, Samarsky stones, thorium stones, tro rubber stones, monazite and the like are included.

The negative ion generation layer I is not limited to the one provided between the buffer layer K and the main body layer 4. One or more of the adhesive, the buffer layer printing agent, the main body layer printing agent, and the top layer printing agent may be mixed with a negative ion generating substance. It becomes an ion generation buffer layer, a negative ion generation main body layer, and a negative ion generation top layer. Further, a negative ion generation layer may be provided between the main body layer 4 and the top layer T. In one example, only the top layer constitutes the negative ion generation layer. A plurality of negative ion generation layers may be formed. In a preferred embodiment, a negative ion generation layer I is provided between the buffer layer K and the main body layer 4, and a negative ion generation material is also mixed into the top layer T. That is, in this, the adhesive layer on the release sheet, the buffer layer on the adhesive layer, the negative ion generation layer on the buffer layer, the main body layer on the negative ion generation layer, and the negative ion generation top layer on the main body layer A decorative body is formed. In addition, since the adhesive which is naturally dried and cured has a short usable time, it is not advantageous to mix a negative ion generating substance into the adhesive.

The decorative body-equipped sheet having a three-dimensional effect will be described with reference to FIG. The process of forming the decorative body is substantially the process described in Example 1, and relates to the base, release sheet, adhesive layer, buffer layer, body layer, top layer, etc. described in Example 1. Since a specific configuration can be used for the description of the third embodiment, details are omitted.

A release sheet 2 is detachably fixed on a base (not shown). The adhesive layer 30 is formed by printing an adhesive on the release sheet using a screen mold. The adhesive layer 30 has an area smaller than the overall shape of the decorative body, and a screen mold corresponding to the adhesive layer 30 having such a small area is prepared in advance.

As the second layer, a buffer layer (not shown) having the same area (the same shape) as the pressure-sensitive adhesive layer 30 is printed on the pressure-sensitive adhesive layer 30 by using the same screen mold as the pressure-sensitive adhesive layer 30. And the upper surface of the adhesive layer 30 is covered. For the advantages of providing the buffer layer, the above description can be referred to, but the buffer layer is not always necessary. This is because the main body layer 400 has a larger area than the adhesive layer 30 and the main body layer 400 is printed so as to enclose the adhesive layer 30. Since the main body layer 400 is usually formed by printing a plurality of times, the adhesive layer 30 is enclosed by the first main body layer printing, and the plate does not directly contact the adhesive layer 30 during subsequent printing.

Next, the main body layer 400 made of urethane resin and / or acrylic resin is formed on the buffer layer using a screen mold corresponding to the decorative body. As is apparent from FIG. 7, the area of the main body layer 400 has a larger area than the adhesive layer 30 and the buffer layer, and has a portion 401 protruding from the adhesive layer 30. The main body layer 400 having an area larger than that of the adhesive layer 30 is formed by using a screen plate having a watermark portion having an area larger than the watermark portion of the screen plate for the adhesive layer using the main body layer printing agent. When a layer is formed or a main body layer is formed using a plurality of screen plates, a main body layer having an area larger than that of the adhesive layer may be obtained as a result. Although the conceptual diagram is shown in the left diagram of the figure, the protruding portion 401 actually adheres on the release sheet 2 as shown in the right diagram. A foaming agent is mixed in the main body layer 400. Although a foaming agent is a thermally expansible microcapsule in a suitable example, the foaming agent used for this invention is not limited to this, It selects from other foaming agents suitably.

On the main body layer, a top layer is formed by printing a urethane resin made of, for example, a solvent resistant (particularly acetone used for nail polish) using a screen mold. The area of the top layer is smaller than the area of the main body layer 400, and in one preferred example, has an area that is substantially the same as or slightly larger than the adhesive layer 30 and the buffer layer. The top layer is not necessarily essential, and the step of forming the top layer after the step of forming the main body layer is optional, but the top layer increases the strength of the product by holding the center of the decorative body, or It has a design effect that expresses a pattern such as an imitation).

Next, the decorative body is subjected to heat treatment. By the heat treatment step, the portion of the main body layer protruding from the adhesive layer 30 and the top layer (only the adhesive layer 30 when there is no top layer) is warped to become a petal (see FIG. 7). The heat treatment step is performed at 130 to 150 ° C. for about 10 to 180 seconds, for example. The means for the heat treatment is not limited, and examples thereof include a heat press and a far red heater. The main body layer is deformed by the heat treatment because the foaming agent is mixed in the main body layer, and the protruding part is attached on the release surface of the release sheet. In the main body layer, the part where the adhesive layer 30 is provided below the main body layer is fixed with an adhesive and foams as a whole. On the other hand, in the main body layer, the portion that is not fixed to the pressure-sensitive adhesive is attached on the release sheet, and is deformed into a concave shape or the like by applying heat. Thus, a sheet having a decorative body composed of an adhesive layer, a buffer layer, a three-dimensional body layer, and a top layer is formed.

Although one main body layer is shown in FIGS. 7A and 7B, the main body layer may be composed of a plurality of layers. In particular, when the pattern has multiple colors, a plurality of main body layers are formed by performing multicolor printing according to the number of colors of the pattern. FIG. 7C shows the multicolor print after the heat treatment. Here, a state in which three independent main body layers are warped is shown. A foaming agent is mixed in the layers constituting the main body layer, and there is a risk that the main body layers positioned above and below are in close contact with each other during heating. Therefore, desirably, release coating is applied to at least one of the opposing surfaces of each layer constituting the main body layer. Or you may comprise the kind of resin which comprises the upper and lower adjacent layer from resin from which a property mutually differs.

The deformation of the portion of the main body layer that protrudes from the adhesive layer 30 is warping in one preferred embodiment, but the deformation of the protrusion portion of the main body layer is not limited to the warping. The deformation mode of the protruding portion of the main body layer is variable depending on conditions such as the area ratio between the adhesive layer and the main body layer, the size of the top layer, the thickness of the main body layer, heat treatment conditions, etc. A three-dimensional effect can be given to a decorative body because a main body layer deform | transforms three-dimensionally from a planar state. Further, the order of forming the adhesive layer and the main body layer may be reversed, and the main body layer may be formed first and the adhesive layer may be formed later as in the process of Example 4 shown in FIG. Moreover, the process of forming the negative ion production | generation layer described in 2nd Example may be included.

Another embodiment will be described with reference to FIG. The thing of Example 4 has the characteristics in the manufacturing process of a decorative body. About the formation means of each layer, the means substantially described in Example 1 is used, and the base, release sheet, adhesive layer, buffer layer, main body layer, top layer described in Example 1, Since the specific structure regarding a drying process etc. can be used for description of Example 4, it abbreviate | omits for details. The configurations of the second and third embodiments can be combined with the fourth embodiment.

The manufacturing method of Example 4 includes the following steps: a first release sheet 2 having a release surface is detachably fixed on a base; a screen mold corresponding to the design of the decorative body is used for the design. A main body layer 4A is formed by printing a stretchable resin having a corresponding color on the release sheet 2; an adhesive is printed on the main body layer 4A using a screen mold corresponding to the substantially entire shape of the decorative body. The second release sheet 20 is fixed on the adhesive layer 3 so as to be peelable. The second release sheet 20 is pressed against the first release sheet 2, the decorative body is transferred to the second release sheet 20, the first release sheet 2 is removed, and the decorative body and the second release sheet are removed. The sheet | seat with a sticking decoration body comprised from the type | mold sheet | seat 20 is obtained (FIG. 8 (A)). Or it is good also as a sheet | seat with a sticking decoration body which clamped the decoration body between the two release sheets 2 and 20, without peeling the release sheet 20 (FIG.8 (B)).

First, a screen mold is produced according to the design of the decorative body. The screen mold to be manufactured includes a screen mold having a watermark portion having a shape corresponding to substantially the entire shape of the decorative body, and, when the decorative body is composed of a plurality of different colors, a portion corresponding to each color. Includes a screen mold with a shape watermark. Further, in Example 4, the decorative body forming process is reversed compared to the other examples, and the screen mold used in Example 4 corresponds to the pattern opposite to the pattern that is actually desired to be configured as the final product. . Note that this is not a limitation as long as the pattern can be reversed.

The release sheet 2 is detachably fixed on the base. The main body layer 4A made of the main body layer printing agent is formed on the release sheet using a predetermined screen mold. FIG. 8 shows three main body layers. The main body layer is printed in multiple colors according to the number of colors of the pattern, and is often composed of a plurality of layers.

Next, the pressure-sensitive adhesive layer 3 is formed by printing a pressure-sensitive adhesive on the main body layer 4A using a screen mold corresponding to the overall shape of the decorative body. A decorative body having the adhesive layer 3 and the main body layer 4A is formed. Since the pressure-sensitive adhesive layer 3 is usually composed of a transparent adhesive, there is no problem even if the pressure-sensitive adhesive layer protrudes somewhat from the main body layer. The buffer layer K may be formed by printing a urethane resin on the adhesive layer between the adhesive layer 3 and the main body layer 4A using a screen mold corresponding to the overall shape of the decorative body. In this case, a decorative body having the adhesive layer 3, the buffer layer K, and the main body layer 4A is formed. A second release sheet 20 is attached to the adhesive layer 3. If the release sheet having the decorative body is peeled off from the base, the decorative body sandwiched between the two release sheets 2 and 20 is obtained.

Before or after the release sheet 2 is peeled from the base, the two release sheets 2 and 20 are pressed against each other, the decorative body is transferred to the second release sheet 20, and the first release sheet 2 is removed (FIG. 8 ( A)). Examples of the pressure contact means for transferring the decorative body include a normal temperature press, a heating press, and a laminator. For example, when a foaming agent is mixed in the resin of the main body layer (including Example 3), heat treatment can be performed after removing the release sheet 2. It is preferable not to transfer the decorative body to the second release sheet 20 when the pattern constituting the decorative body is not integral but separated. The position of the handle separated by the release sheet 2 can be held. That is, the state in which the decorative body is sandwiched between the release sheet 2 and the release sheet 20 is maintained (FIG. 8B). The second release sheet 20 is a protective film that prevents the adhesive layer from adhering to the other. When the decorative body is applied to the nail, first, the release sheet 20 is peeled off and attached to the nail, and then the release sheet 2 fixing the handle is peeled off. 8A may be performed in the state shown in the upper view of FIG. 8A (before being copied to the second release sheet 20), or may be performed in the state shown in the lower view of FIG. You can do this later.
