Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a field in which a fine pattern needs to be printed, and more specifically to a technique for printing a wiring pattern or the like in the production of electric parts, electronic parts and the like.

[0002] In addition, the present invention also provides a useful technique in the case where it is necessary to increase the thickness of the ink in the case where it is necessary for the printing quality to be particularly high even in ordinary printing.

[0003]

2. Description of the Related Art With the progress of electronic technology, the size of devices has become smaller and smaller, and it has been required to miniaturize wiring patterns, and photolithography is mainly used as a solution to this problem. However, there is a strong demand for development of other methods in order to reduce the price. There is also a demand for a pattern forming method with higher accuracy than the conventional technique.

As a new manufacturing method other than photolithography, there is a technique in which ink is cured in an intaglio cell, and the cured ink is peeled off and transferred to the surface of a substrate to which an adhesive has been applied, which is disclosed in JP-A-3-150376. , JP-A-3
-280416 gazette etc. are disclosed.

[0005]

However, there is a problem that the ink cured in the cell may be difficult to peel off from the plate. That is, Japanese Patent Laid-Open No. 3-150376
In the technique of the publication, when a copper plating pattern is formed on a stainless steel plate, the adhesive force between them is so low that it is peeled off by the pressure of washing water. However, in the case of a stainless steel plate-electrodeposition resin or a metal plate other than stainless steel-metal plating pattern, it was extremely difficult to peel and transfer to the adhesive side.

On the other hand, the example of Japanese Patent Laid-Open No. 3-280416 discloses a combination of a copper intaglio plate and an epoxy acrylic ink, but in this case as well, when the ink is completely cured, it can be peeled from the plate. There was a problem that it would be extremely difficult.

As a measure for allowing the ink cured in the intaglio cells to be easily peeled off and transferred to the side of the object to be printed, it is conceivable to arrange a silicone resin or Teflon resin in the intaglio cells. . However, according to a study by the present inventors, it has been difficult to supply the ink into the cell when a normal silicone resin or Teflon resin having excellent releasability is arranged. For example, when trying to supply ink to such an intaglio using an inking roll,
No ink was transferred into the cell and remained on the inking roll. Further, even if the ink was supplied by the doctor ring, the ink once inside the cell adhered to the blade edge of the doctor and was pulled out as the doctor moved, and the inside of the cell became empty.

Therefore, it is possible to find an intaglio plate which can be supplied with ink by an inking roll or a doctor and which allows the hardened ink to be easily released from the mold, a manufacturing method thereof, and a printing method using the intaglio plate. It was a challenge.

[0009]

As a means for solving the problems of the prior art, the present invention provides an intaglio plate in which at least the bottom surface of the cell is formed of a cured ink releasing resin,

Further, the present invention provides an intaglio plate in which the plate surface surrounding the cell is formed of an ink repellent resin.

In the present invention, the cured ink releasable resin has the property of first receiving a liquid (pre-cured) ink, that is, the ink is prepared by a usual method (roll inking, doctor ring, etc.). Secondly, it means a resin having a property of being able to be placed, and secondly, a property of lowering adhesive strength so that the ink can be released from the mold when cured in the plate.

For example, a normal linseed oil-based offset ink is mounted in an uncured state on polyethylene, which is a type of polyolefin resin. That is, inking is possible. However, when the ink is hardened and becomes solid, it easily peels off. For example, when a cellophane tape is stuck on the ink and peeled off, the solid ink is easily peeled off from the polyethylene film. That is, the mold is released.

There are combinations of types of cured ink releasable resin and ink, and there are combinations that provide high releasability, that is, combinations that are excellent in releasability, and vice versa. In the present invention, a combination of an ink-cured ink releasing resin which is easily released by the adhesive strength of the adhesive is targeted.

Polyolefin resins, modified polyolefin resins, polyethylene oxide resins and melamine resins show liquid affinity in the liquid state in contrast to linseed oil type and acrylic type which are generally used as cured inks. But,
When the ink cures, it exhibits releasability. Such characteristics are generally expressed by the combination of the resin and the ink component, but theoretically, the surface tension of the liquid ink is lower than the surface tension of the resin, and wetting occurs, Moreover, it is considered that the surface tension of the cured ink is higher than the surface tension of the corresponding resin, and that no chemical bond is generated between the two. However, at present, this idea does not go beyond the scope of estimation, and in practice, various combinations need to be specifically examined.

The test results of the polyolefin resin, modified polyolefin resin, polyethylene oxide resin, melamine resin, and hydrolyzable silicone resin of the present invention show that among the curable inks, the resin component is linseed oil-based or acrylic-based. As a result, it has been found that it has the above-mentioned characteristic "cured ink releasability". However, the content of the present invention is not limited to this, and is intended for a combination of an ink that exhibits the releasing property of the cured ink, a resin, and an adhesive (adhesive). The adhesive force between the adhesive and the ink needs to be higher than the adhesive force between the cured ink and the resin on the plate surface.

Further, ink capable of accelerating curing is supplied to a cell of an intaglio plate formed by disposing a cured ink releasing resin on at least the bottom surface of the cell and cured in the cell, and the surface of the plate and the material to be printed are cured. After making close contact with the pressure-sensitive adhesive provided on the surface, the pressure-sensitive adhesive is cured or the printing material and the intaglio are separated with the same hardness, and the ink cured in the cell has the adhesive force of the cured adhesive or is not cured. It is intended to provide a printing method using an intaglio plate that is transferred to an object to be printed by the adhesive force of an adhesive.

An ink capable of accelerating curing is supplied to an intaglio cell formed by disposing a cured ink release resin on at least the bottom surface of the cell to cure the ink in the cell, and an adhesive ink is cured. The surface of the plate and the pressure-sensitive adhesive provided on the surface of the substrate to be printed or on the surface of the substrate to be printed are superposed, and the pressure-sensitive adhesive is brought into close contact with the substrate to be printed. Separate the printed matter from the intaglio,
It is intended to provide a printing method using an intaglio plate that transfers an ink cured in a cell and an adhesive to a material to be printed.

Further, the intaglio plate is a uncured ink-repellent resin layer disposed on the upper surface of an intaglio plate, and a cured ink releasable resin layer is peeled off on a convex part of a mother die substrate having a convex part on one surface. A printing method that is formed by arranging the molds so that the cured ink releasable resin layer of the mold is put together and the ink-repellent resin layer is cured, and then the master substrate is removed. Is provided,

A cured ink releasable resin layer is provided on one surface of the intaglio substrate, and a photocurable silicone resin layer is provided thereon.
After pattern-exposing this photocurable silicone resin layer to cure the required portion, the uncured portion is removed, and the ink repellent resin is constituted by the photocurable silicone resin layer,
To provide a printing method formed by exposing a cured ink release resin layer disposed in a lower layer,

A cured ink releasable resin layer is provided on one surface of the intaglio substrate, a photocurable pressure sensitive adhesive layer is provided thereon, and a silicone resin layer is further provided on the photocurable pressure sensitive adhesive layer. After pattern exposure from the silicone resin layer to cure the required portion of the photocurable pressure-sensitive adhesive layer, the uncured portion of the photocurable pressure-sensitive adhesive layer is removed together with the silicone resin of the surface layer portion,
To provide a printing method in which an ink repellent resin is composed of a silicone resin layer and a cured ink release resin layer disposed in a lower layer is exposed.

The present invention provides a printing method in which a liquid of a hardened ink releasing resin supplied to a concave portion of an intaglio plate is solidified to form a hardened ink releasing resin to be disposed on at least a bottom surface of a cell.

After the uncured cured ink releasing resin is brought into close contact with the plate surface of the negative intaglio plate having the concavo-convex portions formed in reverse, the negative intaglio plate is removed to remove the cured ink releasing resin. To provide a printing method formed by disposing an ink-repellent resin on the end surface of a convex portion,

A cured ink releasable silicone resin layer is provided on one side of the intaglio substrate, the cured ink is wet-cured and a metal bonding primer is applied on the cured ink resin layer, and an ultraviolet-curable silicone resin layer is further applied on the primer. The UV-curable silicone resin layer is pattern-exposed to cure the required portion, and then the uncured portion is removed, and the ink-repellent resin is composed of the UV-curable silicone resin layer and is disposed on the lower layer. The present invention provides a printing method formed by exposing the cured ink releasable silicone resin layer.

In the above means for solving, in order for the ink to adhere to the surface of the cured ink releasable resin, the adhesive force must be larger than the cohesive force of the ink itself. Also, in order for the cured ink to be released from the plate and transferred to the adhesive, the adhesive force (cured ink vs. cured ink release resin) <adhesive force (cured ink vs. adhesive) <aggregation The relationship of force (adhesive) and adhesive force (adhesive vs. transfer target) must be established, and it is necessary to confirm that this relational expression is satisfied when selecting each material.

[0025]

Since the intaglio plate having at least the bottom surface of the cell formed by the cured ink releasing resin is used, the ink can be supplied to the cell and the ink which is supplied and hardened in the cell adheres to the inside of the cell. Never. Therefore, after the surface of the material to be printed and the surface of the plate are brought into close contact with each other, when the pressure-sensitive adhesive is cured or the surface of the material to be printed is separated from the surface of the plate with the same hardness, the ink cured in the cells is It is taken up by the adhesive placed on the surface and is all transferred to the side of the printed material.

When the ink is transferred from the intaglio to the side of the printing material, the ink is hardened and does not drip.
Not only is the shape transferred well, but it is possible to obtain a pattern with a thickness that could not be obtained by overlay printing in a single printing.

In an intaglio plate having a plate surface formed of an ink repellent resin, ink is filled only in the cells,
Not only is inking easy, but there is no risk of soiling, so it has excellent operability.

【Example】

(Embodiment 1) An embodiment in which the present invention is applied to etching of a copper layer to obtain a printed circuit board having a required circuit pattern will be described as a first embodiment with reference to FIGS. 1 and 2. .

First, a method of manufacturing the intaglio plate 1 used for printing will be described. For example, a film resist is formed on one surface of an intaglio plate substrate 2 made of a stainless steel plate having a plate thickness of 0.3 mm and 600 mm by a conventionally known method. Negative photoresist (for example, Liston 101 manufactured by DuPont)
0, film thickness 25 μm) at a predetermined temperature and pressure, and the photoresist thus adhered is irradiated with ultraviolet rays in a desired pattern, the unexposed portion is removed by development, and the exposed photoresist 4 is patterned. First, the intaglio substrate 21 that remained on one side like a plate was obtained (step A1).

Next, the intaglio substrate 21 obtained in step A1 is dipped in a nickel plating solution (not shown), the nickel plate is connected to the anode, the intaglio substrate 21 is connected to the cathode, and the nickel plating layer 5 is formed.
In the concave portion surrounded by the photoresist 4,
For example, the intaglio substrate 22 was formed to a thickness of 9.5 μm, then washed with water and dried to obtain an intaglio substrate 22 (step A2). Incidentally, a portion not requiring plating, for example, a side surface or a back surface of the intaglio substrate 21 was masked (not shown) and immersed in a plating solution so that nickel plating was not formed at an unnecessary portion.

The intaglio substrate 22 obtained in step A2 is dipped in a predetermined stripping solution of naphthoquinone diazide (not shown) to remove the photoresist 4, washed with water and dried to form only the nickel plating layer 5 on one surface in a pattern. An intaglio board 23 was obtained (step A3).

Further, the surface of the intaglio substrate 23 obtained in step A3 is spin-coated by a conventionally known method with a primer 6 for metal adhesion (for example, ME-121 manufactured by Toshiba Silicone Co., Ltd.) according to a predetermined method, and then dried. A room temperature curable silicone rubber 7 which is curable at room temperature by adding a specified amount of a curing agent to a silicone rubber (for example, TSE-3450 manufactured by Toshiba Silicone Co., Ltd.) in the concave portion formed by the nickel plating layer 5.
Are treated by the doctor 8 and filled, and left in a room for a predetermined time (for example, 48 hours) to be cured, and then the intaglio substrate 24
Was obtained (step A4).

Then, a suitable tape having an adhesive force on the surface of the intaglio substrate 24 obtained in step A4, for example, cellophane tape 9 is used.
Was attached and peeled off, the nickel plating layer 5 adhered to the cellophane tape 9 was peeled off from the intaglio substrate 2 to obtain an intaglio substrate 25 having a room temperature curable silicone rubber 7 formed on one side in a pattern (step A5).

Furthermore, on the surface of the intaglio substrate 25 obtained in step A5, a chlorinated polyolefin (for example, Sanyo Kokusaku Pulp Co., Ltd. Super Clone 8), which is one of the cured ink releasing resins, is formed.
The film thickness after drying the toluene diluted solution of 22) is, for example, 4 μm.
m is spray-coated, and the solidified chlorinated polyolefin is heated and melted at, for example, 120 ° C. to enhance the adhesion to the substrate surface, and the chlorinated polyolefin on the room temperature curable silicone rubber 7 is pre-processed A5. Similarly, the cell surface surrounding the cell 11 is composed of room temperature curable silicone rubber 7 and the cell bottom surface is formed of a cured ink release resin of chlorinated polyolefin 10 by sticking a cellophane tape or the like and peeling it off. An intaglio plate 1 was prepared (step A6).

An example of use of the intaglio plate 1 prepared as described above will be described below. First, an ultraviolet curing ink (for example, FD-black manufactured by Toyo Ink Co., Ltd.) is applied to the cell 11 by an inking roll or the like not shown. The ink 12 in the cell was cured by supplying it and irradiating it with ultraviolet rays (step A).
7).

On the other hand, a copper layer 14 as an etching target layer is formed on one surface of the substrate 13 to be printed, which is made of glass or polymer resin.
To be printed 1 prepared by coating with a thickness of 10 μm, for example
For example, a positive photoresist 4a (for example, OFPR800 manufactured by Tokyo Ohka Co., Ltd.) and an acrylic adhesive 16 (for example, DA672 manufactured by Diabond Industry Co., Ltd.) were sequentially laminated on the surface of No. 5 to prepare for printing (step. A8).

Then, the intaglio 1 and the material to be printed 15 prepared as described above are placed so as to face each other so that the cured ink 12 and the pressure sensitive adhesive 16 are in contact with each other and pressure-bonded thereto, and then the intaglio 1 and the material to be printed 15 are placed. When the ink was separated, the ink 12 that had hardened in the cells 11 was taken up by the adhesive 16 and was all transferred to the side of the printing material 15 (step A9).

The surface of the material 15 to which the ink 12 is transferred is irradiated with ultraviolet rays to expose the photoresist 4a, which is not shielded by the ink 12, with the ultraviolet rays that have passed through the adhesive 16, and then the ink 12 and the adhesive are applied. 16 is removed by a solvent such as toluene (not shown), and the exposed portion of the photoresist is removed by immersing it in a developing solution to remove the unexposed portion of the photoresist 4a on the copper layer 14 as the layer to be etched. Could be formed in a pattern (step A10).

After the unexposed portion of the photoresist 4a on the copper layer 14 is left in a pattern, the surface of the material to be printed 15 is sprayed with an unillustrated iron solution to etch and remove the exposed portion of the copper layer 14. By washing with water, drying, and removing the photoresist 4a with a stripping solution, a printed product 17 having a desired circuit pattern formed by the copper layer 14 on one surface of the substrate 13 for printing was obtained. (Step A11). The line width was 30 μm at the minimum, but it was clearly formed.

(Embodiment 2) An embodiment in which the present invention is applied to the formation of barrier ribs of a plasma display panel will be described below as a second embodiment.

The partition wall of the plasma display panel is installed between two glass substrates 31 facing each other as indicated by reference numeral 30 in FIG. In addition, the discharge area is limited, and the material is glass containing a black pigment,
Currently, it is mainly formed by screen printing.

In the figure, 32 is a surface mask, 33 is a transparent electrode, 34 is a phosphor, 35 is a nickel cathode, 36 is a dielectric, 37 is a third electrode, and 31 is an upper plate and 31 is a lower plate. Indicates the back plate.

The ink for forming the partition walls 30 is generally composed of glass powder, a black pigment, a binder resin (mainly an acrylic resin) that completely burns when fired, and a solvent. In order to obtain the required thickness (about 120 μm), it was necessary to perform overprinting several times or more.

In Example 2, as the intaglio substrate, a normal amber material having a thickness of 0.3 mm and a length of 450 mm was used. The reason for using the amber material is to reduce the coefficient of thermal expansion and improve the printing accuracy.

The production method and printing procedure of the intaglio plate in the second embodiment mostly overlap with those of the first embodiment shown in FIGS. 1 and 2. Therefore, the following description will be made with reference to FIGS. Part. Further, the same functional portions as those explained in FIGS. 1 and 2 are designated by the same reference numerals in FIG. 3 to facilitate understanding.

In the second embodiment, a nickel plating layer 5 having a required pattern is formed on one surface of the intaglio substrate 2 by using a dry film for plating (not shown) (for example, custom-made Rio Dry DFS manufactured by Toyo Ink Co., Ltd., film thickness 150 μm). Then, the dry film was removed to prepare an intaglio substrate 23 having a nickel-plated portion as a protrusion (step B1).

Then, the primer 6 is spray-coated on the entire surface of the intaglio substrate 23 according to a predetermined method and then dried, and a wet curable silicone resin 18 (which is one of the cured ink releasable resins) is formed thereon. For example, Toshiba Silicone XS66-A6847) has a film thickness of about 5 after curing.
It was spray-coated so as to have a thickness of μm, and was humidified and cured to obtain an intaglio plate 1 having a plate depth of 130 μm (step B2).

As the ink used for printing, a catalyst-curable acrylic resin (for example, Acryfix manufactured by Marumoto Kogyo Co., Ltd.) is used as a binder component, and glass powder / black pigment is used to the same extent as the screen ink used for this purpose. Just before use, a prescribed amount of a prescribed curing catalyst was added and stirred, and the cells 11 of the intaglio 1 were filled with a doctor ring and left in a room for a prescribed time to cure the ink 12 (step B3). ).

Intaglio 1 in which ink 12 is cured in cell 11
And a glass substrate 31 as a material to be printed on the surface of which an acrylic adhesive 16 to which a curing agent has been applied are aligned and faced to each other. When peeled off, all the ink 12 cured in the cell 11 was taken by the adhesive 16 and transferred to the glass substrate 31 side (step B4).

The glass substrate 31 on which the ink 12 is transferred is
As in the prior art, for example, 50
When heated at 0 ° C. for 70 minutes, the adhesive 16 burns,
The solid matter obtained by burning the non-combustible component of the ink 12 remained in close contact with the surface of the glass substrate 31, and the partition wall 30 having a line width of 80 μm and a height of 120 μm was formed by one printing (step B5).

Further, the intaglio can be formed according to the process shown in FIG. That is, a glass substrate 31 is spin-coated with a water-soluble resin 51 such as polyvinyl alcohol so that the dry film thickness is, for example, 20 μm, and a positive type photoresist for thick film for a printing substrate (for example, , AZ4903 manufactured by Hoechst Japan Co., Ltd. is spin-coated so that the dry film thickness is, for example, 8 μm, and this is irradiated with ultraviolet rays in a required pattern, immersed in a mixed developing solution of xylene and isopropyl alcohol, and exposed. The photoresist in the exposed portion is removed, and the master substrate 41 having a desired pattern on one surface is first formed by leaving the photoresist 4 in the unexposed portion (step C1).

Next, a small amount of water is used as dampening water and the mother substrate 4 is used.
1 and then the cured ink releasable resin ink containing the silane coupling material is supplied by the inking roller to form a layer of the cured ink releasable resin ink 43 on the pattern of the photoresist 4. , This is hardened and mold making master 4
4 is created (step C2).

Here, the hardened ink releasing resin ink means the ink in which the hardened ink releasing resin is dissolved in a solvent or made into an emulsion state so that it can be inked by an inking roller. Further, as a method for curing, various methods suitable for a cured ink release resin such as ultraviolet curing, heat melting coagulation and two-component curing are used.

Since the surface of the water-soluble resin 51 is hydrophilic and the photoresist 4 is water repellent, a small amount of water on the master substrate 41 is placed only on the surface portion of the water-soluble resin 51. When the cured ink release resin ink 43 is supplied in this state, the cured ink release resin ink 43 adheres only to the water-repellent photoresist 4 portion. In other words, it has the same mechanism as the ink supply to the offset printing plate.

Next, a glass intaglio substrate 2 having a thickness of 5 mm
A primer 6 for metal adhesion (for example, ME-121 manufactured by Toshiba Silicone Co., Ltd.) is applied to the surface of the above, and a thickness of 1 m is applied on the primer.
A frame 45 of 140 mm square is made from four stainless steel sheets each having a width of 20 mm and a width of 20 mm, and a mixture of silicone rubber (for example, TSE-3466 manufactured by Toshiba Silicone Co., Ltd.) to which 10% of a predetermined curing agent is added and mixed is injected. A mold making master 44 was placed on the mold, and left for a predetermined time to cure the room temperature curable silicone rubber 7 and mold it (step C3).

The frame 45 is removed, and the room temperature curable silicone rubber 7 is modeled and dipped in an alkaline aqueous developer (eg, AZ400K manufactured by Hoechst Japan) to dissolve the water-soluble resin 51 for a sufficient time. Then, the glass substrate 31 is removed, and when the immersion is continued, the photoresist 4 is removed, and the UV curable ink 43 that has been inked and hardened in the photoresist 4 is surrounded by the room temperature curable silicone rubber 7 and formed into a cell. The intaglio 1 provided on the bottom surface of the cell 11 and provided with the cured ink releasing resin layer was formed on the bottom surface of the cell 11 (step C4). The intaglio plate 1 thus formed had no jagged edges around the pattern having a line width of 5 μm and was suitable for printing a fine pattern.

Further, as shown in FIG. 6, a cured ink releasing resin 52 formed on one surface of the intaglio substrate 2 to have a uniform thickness.
The intaglio 1 may be prepared by forming a convex portion of the ink-repellent resin 53 in a desired pattern on the above. The intaglio plate having this structure can be easily produced by forming the ink-repellent resin 53 with a photocurable silicone resin or the like.

That is, the ink-repellent resin 53 is first formed on the cured ink releasable resin 52 by, for example, spin coating to form a uniform film thickness, and the ink-repellent resin 53 is not pattern-exposed. When the cured portion is removed, the cured ink releasing resin 52 disposed in the lower layer is exposed, the plate surface is the ink repellent resin 53, and the bottom surface of the cell 11 is the cured ink releasing resin 5.
An intaglio that is 2 is formed.

Further, as shown in FIG. 7, a cured ink releasing resin 52 formed on one surface of the intaglio substrate 2 to have a uniform thickness.
It is also possible to form a convex portion by a laminated portion of the pressure sensitive adhesive 16 and the ink repellent resin 53 on the above in a desired pattern to form the intaglio 1.

The intaglio plate 1 having this structure has a uniform film formed by spin-coating a cured ink releasable resin 52 with, for example, a photocurable adhesive and an ink repellent resin such as a silicone resin. After stacking thickly, the photo-curable adhesive is pattern-exposed on the ink-repellent resin to partially cure the adhesive, and then immersed in the required solvent to allow the solvent to penetrate into the ink-repellent resin. , If the ink repellent resin is rubbed and developed, and the ink repellent resin on it is removed together with the dissolved adhesive,
The cured ink release resin 52 disposed in the lower layer is exposed,
An intaglio plate is formed in which the plate surface is the ink repellent resin 53 and the bottom surface of the cell 11 is the cured ink release resin 52.

Further, as shown in FIG. 8, a convex portion 54 is formed in a required pattern on one surface of the intaglio substrate 2 by a convex portion forming material made of metal or photoresist and formed on the upper surface of the convex portion. A layer of an ink repellent resin 53 made of a silicone resin, a Teflon resin, or the like is formed, and a cured ink release resin 5 is formed in a concave portion 55 surrounded by the convex portion 54.
It is also possible to dispose 2 to form the intaglio 1. In addition, the intaglio plate having this configuration may be configured without the ink-repellent resin 53.

The intaglio plate 1 having this structure is formed by a method in which the liquid in which the cured ink releasing resin 52 is melted is supplied to the recess 55 and then solidified. As a method of supplying the liquid only to the concave portion 55, there is a method of supplying the liquid by using a roll inking or a doctor ring after the convex forming material 54 is made liquid repellent in addition to the doctor ring.

As a method for making the convex portion 54 liquid-repellent,
There is a method of disposing a solution-repellent resin layer such as a silicone resin or a Teflon resin on the convex portion, or using a hydrophilic metal such as chromium (trimetal intaglio), or forming a hydrophilic resin layer. As a method of providing the hydrophilic resin layer on the convex portion 54, the concave portion 5
There is a method in which the ink is supplied to No. 5 by doctoring, the solution of the hydrophilic resin is then supplied to the entire surface, and the solution is solidified, and then the ink in the recess 55 is dissolved with a solvent that does not dissolve the hydrophilic ink. Solution-repellent resins such as silicone resins and Teflon resins can be similarly formed. As a method for solidifying, a method of polymerizing a resin may be adopted.

Further, as shown in FIG. 9, a cured ink releasing resin 52 is provided on one surface of the intaglio substrate 2 via a layer of adhesive or pressure sensitive adhesive 16, and a convex portion 54 and a concave portion 55 are formed on this surface. It is also possible to form a desired pattern and form a layer of ink-repellent resin 53 such as silicone resin or Teflon resin on the convex portion 54 to form the intaglio 1. In addition, the intaglio plate having this configuration may be configured without the ink-repellent resin 53, the intaglio substrate 2, and the adhesive 16.

The intaglio having this structure is formed by pattern etching.
First, a negative intaglio in which the irregularities are reversed by pattern plating, photoresist patterning, etc. is formed, and a cured ink release resin that is made flowable by heat melting, solvent dissolution, etc. is placed in the concave of the negative intaglio. Pouring and solidifying,
It is also possible to form the recesses 55 to be the cells 11 by the cured ink release resin 52 by pressing a heated cured ink release resin into a negative intaglio plate in a plastically workable state.

The ink-repellent resin 53 made of silicone resin, Teflon resin or the like is provided on the end surface of the convex portion 54 to form the intaglio 1.

As a method of disposing the ink-repellent resin 53 made of silicone resin, Teflon resin or the like on the end surface of the convex portion 54 made of the cured ink releasing resin 52, the intaglio 1 shown in FIG. The preparation procedure is used.

By the way, as the cured ink releasable resin 52 disposed on at least the bottom surface of the cell 11, a printing oil-based ink such as a polyolefin resin, a modified polyolefin resin, a polyethylene oxide resin, a melamine resin, or a hydrosetting silicone resin is used. Can accept and
A resin that allows the cured ink to be peeled off relatively easily is appropriately selected and used.

[0069]

As described above, in the intaglio plate of the present invention, since at least the bottom surface of the cell is formed by the cured ink releasing resin, even if the ink supplied to the cell is cured in the cell, the ink remains There is no close contact with the cell. Therefore, after the surface of the substrate to be printed and the plate surface are adhered to each other, if the surface of the substrate to be printed and the plate surface are separated, the ink that has been cured in the cells is taken up by the adhesive on the surface of the substrate to be printed. All is transferred to the side of the printing material.

When the ink is transferred from the intaglio to the side of the printing material, the ink is hardened and does not drip, so that a fine pattern can be formed in a good shape, and it can be obtained conventionally unless overprinting. It became possible to obtain a pattern with such a thickness as never before by printing once.

In an intaglio plate having the plate surface made of an ink repellent resin, ink is filled only in the cells, so that inking is easy and there is no fear of causing scumming. There is a feature that is said to be excellent.
