Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transferring and printing a predetermined pattern on a mesh sheet such as gauze or gauze.

Conventional technology As a method of attaching characters and patterns to book covers, plastic containers, home appliances, leather, cloth, etc., after metal is vapor-deposited on a film such as polyester film, heat-melt adhesive is applied to the vapor-deposited surface. A method of hot-stamping a foil using a metal-deposited film coated with an agent is widely used.

Also, recently, as a method of forming a color pattern on a through-hole cloth, a heat-sensitive adhesive is applied to an arbitrary pattern on the transfer film surface of a transfer foil in which a transfer film is laminated on the upper surface of a base material sheet via a release agent layer. Alternatively, a partially coated pattern may be used, and a perforated cloth and a release sheet may be sequentially stacked on the transfer film side of the transfer foil. A method has been proposed in which the transfer foil and the release sheet are separated from the through-hole cloth after they are adhered to each other only. (See Japanese Patent Publication No. 59-44431) Problems to be Solved by the Invention However, in the method of hot stamping by the hot stamping method described above, when the object is a mesh-like sheet such as gauze or gauze, the foil is There is a problem in that the wire is only adhered only to the line portions constituting the mesh, so that the mesh is peeled off at the hole portion.

On the other hand, in the method disclosed in Japanese Patent Publication No. 59-44431, there is an advantage that the transferred pattern or pattern does not peel off even if the object is a mesh sheet, but the mesh sheet has a pattern. When transferring a pattern or pattern, it is required to use a fine pattern or pattern so that the transfer material does not block the mesh eyes and impair the texture, but depending on this method, a fine pattern or pattern However, it was not always satisfactory in terms of sharpness of patterns and patterns obtained by transfer.

The present invention has been made to solve such conventional problems.

Means for Solving the Problems In the transfer printing method of the present invention, a laminated sheet (4) having a constitution in which a transfer layer (3) is laminated on a support layer (1) via a release agent layer (2). The mesh sheet (5) is superposed on the transfer layer (3) side surface of the mesh sheet (5).
The adhesive (7) is imprinted onto the transfer layer (3) through a screen (6) so as to reach the transfer layer (3), and after the completion of the adhesion, the mesh-like sheet (5) is pulled out of the laminated sheet (4). The transfer layer (3) corresponding to the pattern is transferred onto one surface of the mesh-like sheet (5) by peeling it off.

Further, the transfer printing method of the present invention prepares two laminated sheets (4) having a structure in which a transfer layer (3) is laminated on a support layer (1) with a release agent layer (2) interposed therebetween, and 1 A mesh-like sheet (5) on the transfer layer (3) side surface of a single laminated sheet (4)
And the adhesive sheet (7) is imprinted on the mesh sheet (5) through the screen (6) so as to reach the transfer layer (3) through the screen (6), and then the adhesive sheet (7) is printed. The other laminated sheet (4) from the insertion side is the mesh sheet (5) with the transfer layer (3) side.
And the upper and lower laminated sheets (4) and (4) are peeled off from the mesh-like sheet (5) after the completion of the adhesion, and the upper and lower sides of the mesh-like sheet (5) according to the pattern are overlapped. The transfer layers (3) and (3) are transferred.

By finding such a specific method, the above conventional problems have been completely solved.

Hereinafter, the method of the present invention will be described in detail.

1 and 2 are schematic cross-sectional views showing an example in which the transfer printing method of the present invention is performed to transfer a pattern to one side of a mesh-like sheet, and FIG. 1 is a state before a transfer operation. 2 shows the state after the transfer operation.

FIG. 3 is a schematic cross-sectional view showing an example in which the transfer printing method of the present invention is carried out to transfer a pattern to both surfaces of a mesh-like sheet.

I. Laminated sheet (4) In the present invention, as shown in FIG. 1, a laminated sheet having a constitution in which a transfer layer (3) is laminated on a support layer (1) via a release agent layer (2). (4) is used.

Support Layer (1) As the support layer (1), various films such as a polyester film, a biaxially oriented polypropylene film and a cellulosic film are used.

Release Agent Layer (2) The release agent layer (2) provided on the surface of the support layer (1) is
The coating layer is composed of a silicone release agent, a fluororesin release agent, a long chain alkyl acrylate, an alkyl vinyl ether, an alkyl acrylamide, a copolymer of an alkyl allyl ester, or the like.

Transfer layer (3) As the transfer layer (3) laminated on the support layer (1) via the release agent layer (2), the anchor coat is arranged in the order of closer to the release agent layer (2). A layer (3a), a thin metal layer (3b) and a cover resin layer (3c) are preferably used.

Here, the thin metal layer (3b) is preferably a layer formed by a vacuum thin film forming method, that is, vacuum deposition, ion plating, sputtering or the like. Examples of the metal include aluminum, gold, silver, cuprous, nickel, chromium, titanium, stainless steel, iron, cobalt, molybdenum, rhodium, palladium, indium, tin, tantalum, platinum, and the like. Used in the form of alloys or mixtures. As the thin metal layer (3b), a foil produced by rolling a metal can be used as the case may be.

The anchor coat layer (3a) is composed of a coating layer of various thermoplastic resins or thermosetting resins such as acrylic resin, epoxy resin, vinyl chloride-vinyl acetate copolymer, and this layer (3a) is a thin metal layer. It is also a layer that traps metal vapor when the layer (3b) is formed and a layer that protects the metal thin layer (3b) after transfer. Further, if a transparent resin is used for forming the layer (3a), the transfer pattern has a gloss of metal itself, and if a colored resin is used for forming the layer (3a), a layer is also provided with metal coloring.

The cover resin layer (3c) is a layer that protects the thin metal layer (3b), and is made of the same resin coating layer as the anchor coat layer (3a). This layer (3c) does not need to be colored, but it can be colored.

As the transfer layer (3), the one having the cover resin layer (3c) omitted from the above-mentioned structure can be used. Also,
The transfer layer (3) may be composed of only the colored resin layer without using the thin metal layer (3b).

B. Transfer Operation (Single-sided Transfer) In the present invention, as shown in FIG. 1, the mesh sheet (5) is laid on the surface of the above-mentioned laminated sheet (4) on the transfer layer (3) side.

As the mesh sheet (5), various materials such as gauze, gauze, woven fabric, non-woven fabric and net are used. The material of the mesh sheet is not particularly limited, and synthetic fibers (acrylic fiber, nylon fiber, polyester fiber, urethane fiber, polyolefin fiber, polyvinylidene chloride fiber, vinyl alcohol fiber, etc.), cellulosic fiber , Recycled fibers, natural fibers, inorganic fibers (metal fibers, glass fibers, whiskers, etc.), carbon fibers and the like are used.

After the mesh sheet (5) is laid on the surface of the laminated sheet (4) on the transfer layer (3) side, the mesh sheet (5) is formed.
The adhesive (7) is imprinted onto the transfer layer (3) from above through a screen (6) in a predetermined pattern.

As the screen (6), polyester, nylon,
A plate made of a flat mesh made of silk, stainless steel, or the like is used, but a cylindrical screen plate can also be used.

As the adhesive agent (7), in addition to a normal solution or dispersion type adhesive agent capable of adhering by volatilization of volatile components, a thermosetting type adhesive agent, a room temperature curing type adhesive agent, and a photocuring type adhesive agent A tacky adhesive, or a hot melt adhesive that melts by heating to exert an adhesive force is used.

Imprinting of the adhesive (7) is performed by placing the adhesive (7) on the screen (6) and then operating a squeegee.
When performing rotary screen printing using the cylindrical screen (6), the squeegee is built in the cylinder, so it is only necessary to rotate the rotary screen. In the latter rotary screen method, the plate is released at the same time as printing, so that the adhesive (7) can be printed uniformly on the mesh sheet (5), and high-speed printing is possible because it is printing by rotary motion. Since the adhesive is inside the cylindrical screen (7), the solvent is less volatile and dust is less likely to enter, which is advantageous in that the characteristics of the adhesive (7) can be kept constant. .

When the adhesive (7) is imprinted, the adhesive (7) passes through the mesh sheet (5) and reaches the transfer layer (3) of the transfer sheet (4). Is completed, only the contact portion of the transfer layer (3) with the adhesive (7), that is, the pattern portion is firmly adhered to the mesh sheet (5).

Then, after the adhesion is completed, the laminated sheet (4) is peeled off from the mesh sheet (5) as shown in FIG. 2, and the transfer layer (3) corresponding to the pattern is formed on one surface of the mesh sheet (5). Is transferred to obtain the desired product.

C. Transfer Operation (Double-sided Transfer) When performing double-sided transfer, two sheets of the above laminated sheet (4) are prepared, and one of them is used in the same manner as described above, and the surface of the laminated sheet (4) on the transfer layer (3) side The mesh-like sheet (5) is superposed on the sheet, and the adhesive (7) is imprinted on the mesh-like sheet (5) through the screen (6) so as to reach the transfer layer (3) in a predetermined pattern.

Further, another laminated sheet (4) is superposed from the imprinted side of the adhesive (7) so that the transfer layer (3) side faces the mesh-like sheet (5) and pressure-bonded.

In this case, as the adhesive (7), an adhesive of a type that can be adhered by volatilization of volatile matter may be used, but since the patterns of the upper and lower transfer layers (3) and (3) may be displaced during pressure bonding, it is hot. It is more practical to imprint a melt type adhesive (7) and then dry it, then stack another laminated sheet (4) from the imprinted side, heat and melt, and then cool to achieve adhesion. is there.

After completion of the adhesion, as shown in FIG. 3, the upper and lower laminated sheets (4) and (4) are peeled off from the mesh sheet (5) to form the pattern on both sides of the mesh sheet (5). The corresponding upper and lower transfer layers (3) and (3) are transferred to obtain the intended product.

Action The adhesive (7) is imprinted on the mesh sheet (5) placed on the transfer sheet (4) according to the method of the present invention in a predetermined pattern through the screen (6).
Reaches the transfer layer (3) of the transfer sheet (4) through the eyes of the mesh sheet (5). Therefore, if the adhesion is completed in this state, the transfer layer (3) and the adhesive (7) Only the contact portion, that is, the pattern portion, is firmly adhered to the mesh sheet (5).

Then, when this state is reached, the mesh sheet (5)
When the laminated sheet (4) is peeled from the sheet, the transfer layer (3) corresponding to the pattern is transferred to the mesh sheet (5).

EXAMPLES Next, the transfer printing method of the present invention will be further described with reference to examples.

Example 1 A support layer (1) made of a polyester film having a thickness of 12 μm was coated with a silicone release agent to form a release agent layer (2), and a colored acrylic resin emulsion was further coated thereon. To form an anchor coat layer (3a). This anchor coat layer (3
a) Aluminum was vacuum-deposited on the surface to form a thin metal layer (3b), and a non-colored acrylic resin emulsion was coated on the thin metal layer (3b) to form a cover resin layer (3c). Thereby, the support layer (1)

A laminated sheet (4) having a structure in which a transfer layer (3) consisting of / metal thin layer (3b) / cover resin layer (3c) was laminated was obtained.

As shown in FIG. 1, a polyester fiber mesh sheet (5) is laid on the transfer layer (3) side surface of the laminated sheet (4) obtained above, and the mesh sheet (5) is placed on the mesh sheet (5). After closely contacting the screen (6), an acrylic adhesive (7) was imprinted on the screen (6) with a squeegee through the screen (6) and naturally dried.

When the laminated sheet (4) was gently peeled off from the mesh sheet (5) after drying, as shown in FIG. 2, only the transfer layer (3) at the adhesive (7) adhering portion was the mesh sheet (5). ) Strongly transferred and adhered to one surface.

The transfer pattern on the mesh sheet (5) was extremely beautiful, and no defects were found even in the details of the pattern.

Example 2 In Example 1, transfer printing was performed using the flat screen (6), but in this Example, transfer printing was performed using the rotary screen (6).

That is, supply of the laminated sheet (4), supply of the mesh sheet (5), lamination of the mesh sheet (5) on the laminated sheet (4), imprinting of the adhesive (7) with the rotary screen (6), Drying with hot air by passing through a drier, laminated sheet (4) from mesh-like sheet (5) after drying
Was peeled off, and the transfer-printed mesh sheet (5) and the laminated sheet (4) were continuously wound up.

The transfer operation was smooth, and the target product could be manufactured with extremely high productivity.

Example 3 The adhesive (7) was imprinted in the same manner as in Example 1 except that an acrylic hot-melt type adhesive was used as the adhesive (7), and was naturally dried.

Next, another laminated sheet (4) is placed on the imprinted side of the adhesive (7) so that the transfer layer (3) side faces the mesh-like sheet (5), and the adhesive is applied by heating and pressing. After melting (7), it was cooled to room temperature.

After the bonding is completed, the upper and lower laminated sheets (4) are gently peeled off from the mesh-like sheet (5), and as shown in FIG. 3, the transfer layers (3) and (3) at the adhesive (7) -attached portion are shown. Only the film firmly adhered to both sides of the mesh sheet (5).

The transfer pattern on the mesh sheet (5) was extremely beautiful, and no defects were found even in the details of the pattern.

EFFECTS OF THE INVENTION According to the method of the present invention, the transferred pattern does not peel off even though the object is a mesh sheet.

Moreover, even fine patterns can be reproduced and transferred to the mesh sheet without missing even the smallest details.
The pattern can be made more delicate than in the conventional method. Further, since the meshes are less likely to be blocked due to the delicate pattern, the change in the texture of the mesh-like sheet due to the transfer is further reduced.

In addition, the method of the present invention has a relatively simple process, and thus is preferable in terms of productivity.
