Description

本発明は、グラビア印刷用凹版、粘着剤の塗布用凹版、レジスト材料の転写塗布用凹版、カラー液晶表示装置に用いるカラーフィルタ等の精細パターンを形成するための凹版などの凹版及びその製造方法に関する。   The present invention relates to an intaglio such as an intaglio for gravure printing, an intaglio for application of an adhesive, an intaglio for transfer application of a resist material, an intaglio for forming a fine pattern such as a color filter used in a color liquid crystal display device, and a method for producing the same. .

従来、グラビア印刷用凹版、粘着剤の塗布用凹版、レジスト材料の転写塗布用凹版、カラー液晶表示装置に用いるカラーフィルタ等の精細パターンを形成するための凹版などの凹版は、印刷用インク、粘着剤等を保持する凹部が形成されている。このような凹版は、通常、鉄等の金属製のロール状或いは板状の基材上にエッチングが容易な金属銅を電気めっきし、その上に感光性樹脂を塗布後レーザ露光により直接潜像を形成し、不要部分の樹脂を除去して(現像して)エッチングレジストパターンを形成し、次いで、エッチングを行い、さらに樹脂を剥離する方法により作製されている。このようにして得られた凹版は、耐刷性向上の目的で表面に例えば電気ニッケルめっきあるいは電気クロムめっきが施こされることが多い(以上、特許文献1、2参照)。   Conventional intaglios such as intaglios for gravure printing, intaglios for application of adhesives, intaglios for transfer application of resist materials, intaglios for forming fine patterns such as color filters used in color liquid crystal display devices, printing inks, adhesives A recess for holding the agent and the like is formed. Such an intaglio is usually formed by electroplating metal copper, which is easy to etch, on a roll or plate made of a metal such as iron, and after applying a photosensitive resin thereon, a direct latent image is obtained by laser exposure. Is formed by removing (developing) unnecessary portion of the resin to form an etching resist pattern, then performing etching, and further peeling the resin. The surface of the intaglio plate thus obtained is often subjected to, for example, electro nickel plating or electro chrome plating for the purpose of improving printing durability (see Patent Documents 1 and 2 above).

従来、前記凹版は、前述のように工程が長いという問題があり、またエッチング工程を有しているため、また、さらに、電気クロムめっきをする場合には、高精度な形状付与が困難であり、凹部の均一な形状、凹部エッジの真直性、凹部深さの精度を得るのが困難であった。
また、最近では、エッチング後の電気クロムめっきの代替として、無機材料である酸化ケイ素層、窒化チタン層、或いはダイヤモンドライクカーボン(DLC)層等が適用されているが、高精度は形状付与が困難な金属のエッチングを要することは変わらない。
Conventionally, the intaglio has a problem that the process is long as described above, and also has an etching process. Further, when electrochromic plating is performed, it is difficult to give a highly accurate shape. It was difficult to obtain a uniform shape of the recess, straightness of the recess edge, and accuracy of the recess depth.
Recently, as an alternative to electrochrome plating after etching, silicon oxide layers, titanium nitride layers, diamond-like carbon (DLC) layers, etc., which are inorganic materials, have been applied. It still does not change the need for metal etching.

本発明は、このような問題点に鑑み、凹部の均一な形状、凹部エッジの真直性、凹部深さの精度が得やすく、さらに、耐久性に優れる凹版を提供するものであり、さらに、このような凹版の製造方法、特に、高精度は形状付与が困難な金属のエッチングを不要とし、また、電気クロムめっきを不要とし、生産効率の良い凹版の製造方法を提供するものである。   In view of such a problem, the present invention provides an intaglio which is easy to obtain the uniform shape of the recess, the straightness of the recess edge, and the accuracy of the recess depth, and is excellent in durability. A method of manufacturing such an intaglio plate, in particular, an etching method for producing an intaglio plate with high production efficiency, which eliminates the need for metal etching that is difficult to impart a shape with high accuracy and eliminates the need for electrochrome plating.

本発明における凹版は、凹部の均一な形状、凹部エッジの真直性、凹部深さの精度が達成しやすく、これは、該凹版の製造に際し、高精度困難な基材のエッチングを不要とし、高精度困難な電気クロムめっきを不要であることも一因している。したがって、本発明に係る凹版を用いることにより、より均一で、より精密かつより正確な転写塗布が可能である。
本発明における凹版は、基材上に凸状のパターンを形成し、膜を形成後に、凸状のパターンを除去することにより凹部を作製することができるため、その製造が容易で、生産性に富む。
本発明における凹版は、グラビア印刷用凹版、粘着剤塗布用凹版に有用である。本発明における凹版は、さらに、レジストの転写塗布用凹版、カラー液晶表示装置に用いるカラーフィルタの精細パターンを形成するためのカラーフィルタ用インクのガラス基板等の基板への転写塗布用凹版などに有用であり、これらは、精密電子部品等の微細な構造物の製造工程において有用に用いることができる。

The intaglio in the present invention easily achieves a uniform shape of the recess, straightness of the recess edge, and accuracy of the recess depth, which eliminates the need for high precision and difficult etching of the base material in the manufacture of the intaglio. This is partly because electrochromic plating, which is difficult to be accurate, is unnecessary. Therefore, by using the intaglio according to the present invention, more uniform, more precise and more accurate transfer coating is possible.
Since the intaglio in the present invention can form a concave pattern by forming a convex pattern on the substrate and removing the convex pattern after forming the film, its manufacture is easy and productivity is improved. Rich.
The intaglio in the present invention is useful for gravure intaglio and pressure sensitive adhesive intaglio. The intaglio in the present invention is further useful as an intaglio for resist transfer coating, an intaglio for transfer coating on a substrate such as a glass substrate of color filter ink for forming a fine pattern of a color filter used in a color liquid crystal display device, and the like. These can be usefully used in the manufacturing process of fine structures such as precision electronic components.
Furthermore, the surface of the intaglio plate is made of diamond-like carbon or an inorganic material, resulting in excellent wear resistance. When a film made of diamond-like carbon or an inorganic material is formed on the surface of the intaglio plate, the adhesion to the substrate is excellent, and its peeling resistance is excellent. Excellent in properties. The adhesion between the substrate and the film can be improved by the intermediate layer, and thereby the life of the intaglio can be further increased for repeated use.

本発明に係る凹版の製造方法によれば、工程数が少なく、特に、開口方向に向かって幅広の凹部を容易に作製することができるため、それを生産効率よく製造することができる。   According to the method for producing an intaglio according to the present invention, the number of steps is small, and in particular, since a wide concave portion can be easily produced in the opening direction, it can be produced with high production efficiency.

本発明の一例を図面を用いて説明する。
図1は、本発明の凹版の一例を示す一部斜視図である。図2は、図1のA−A断面図を示す。図2の(a)は凹部の側面が平滑に平面的であるが、(b)は凹部の側面になだらかな凹凸がある場合を示す。凹版1は、ベースとなる基材2の上にダイヤモンドライクカーボン(以下、「DLC」と略す)の膜(本発明おいて、「膜」には、「層」という概念も含ませる)3が積層されており、DLC膜3に凹部4が形成されており、凹部4の底部は、凹版用基材2が露出している。
この例において、凹部4が溝状に形成されているが、目的に応じて、適宜の形状が形成される。凹部4の平面形状は、正三角形、二等辺三角形、直角三角形などの三角形、正方形、長方形、ひし形、平行四辺形、台形などの四角形、(正)六角形、(正)八角形、(正)十二角形、(正)二十角形などの(正)n角形(nは3以上の整数)、円、だ円、星型などがあり、目的に応じてその形状が選択される。このような形状は、組合せて使用できる。また、凹部の分布密度は、目的応じて適宜決定される。
基材2と膜3の間には、膜3の接着性の改善等を目的として、中間層(図示せず)が積層されていてもよい。または、凹部4は、その幅が、開口方向に向かって全体として幅広になっている。図面のよう勾配αで一定に幅広になっている必要は必ずしもない。印刷インクの転写に問題がなければ、凹部は、開口方向に向かって幅が狭くなっている部分があってもよいが、このような部分がない方が良く、凹部は開口方向に向かって狭まっておらず全体として広がっていることが好ましい。
An example of the present invention will be described with reference to the drawings.
FIG. 1 is a partial perspective view showing an example of the intaglio of the present invention. FIG. 2 is a cross-sectional view taken along the line AA in FIG. FIG. 2A shows a case where the side surface of the recess is smooth and planar, while FIG. 2B shows a case where the side surface of the recess has gentle irregularities. The intaglio 1 has a diamond-like carbon (hereinafter abbreviated as “DLC”) film 3 (in the present invention, “film” includes the concept of “layer”) 3 on a base material 2 serving as a base. The concave portions 4 are formed in the DLC film 3, and the intaglio substrate 2 is exposed at the bottom of the concave portions 4.
In this example, the recess 4 is formed in a groove shape, but an appropriate shape is formed according to the purpose. The planar shape of the concave portion 4 is a triangle such as a regular triangle, an isosceles triangle, a right triangle, a square, a rectangle, a rhombus, a parallelogram, a trapezoid or other quadrangle, a (positive) hexagon, (positive) octagon, (positive) There are (positive) n-gons (n is an integer greater than or equal to 3) such as a dodecagon and (positive) icosahedron, a circle, an ellipse, and a star, and the shape is selected according to the purpose. Such shapes can be used in combination. Further, the distribution density of the recesses is appropriately determined according to the purpose.
An intermediate layer (not shown) may be laminated between the substrate 2 and the film 3 for the purpose of improving the adhesiveness of the film 3 or the like. Alternatively, the recess 4 is wide as a whole in the opening direction. It is not always necessary that the width is constant and wide at the gradient α as shown in the drawing. If there is no problem in printing ink transfer, the concave portion may have a portion whose width becomes narrower in the opening direction, but it is better not to have such a portion, and the concave portion narrows in the opening direction. It is preferable that it spreads as a whole.

凹部の側面は、必ずしも平滑に平面的ではない。この場合には、図2(b)に示すように、前記の勾配αは、凹部の高さhと凹部の側面の幅s(水平方向で凹部の側面の幅方向に測定する)を求め、

Figure 2008254331
によってαを決定する。
αは、角度で30度以上90度未満が好ましく、30度以上60度以下が特に好ましい。これにより、印刷インク、粘着剤、レジスト用材料、カラーフィルタ用インク等の転写物が、容易に転写される。 The side surface of the recess is not necessarily smooth and flat. In this case, as shown in FIG. 2 (b), the gradient α obtains the height h of the recess and the width s of the side surface of the recess (measured in the width direction of the side surface of the recess in the horizontal direction)
Figure 2008254331
Determines α.
α is preferably 30 ° or more and less than 90 °, and particularly preferably 30 ° or more and 60 ° or less. Thereby, transfer materials, such as printing ink, an adhesive, a resist material, and color filter ink, are easily transferred.

また、膜の厚さは、0.1μm以上100μm以下の範囲であることが好ましい。膜が厚すぎると、膜を形成する時間が長くなり、作業効率が低下しやすくなる。また、膜が薄すぎるとインク、粘着剤その他の転写物の保持量が減り、印刷むら、塗布むら等が起こり転写にむらが出来やすくなる。膜の厚さは、5〜30μmであることが特に好ましい。   The thickness of the film is preferably in the range of 0.1 μm to 100 μm. If the film is too thick, it takes a long time to form the film and the working efficiency tends to decrease. On the other hand, if the film is too thin, the amount of ink, pressure-sensitive adhesive or other transferred material is reduced, resulting in uneven printing, uneven coating, and uneven transfer. The thickness of the film is particularly preferably 5 to 30 μm.

ここで、凹部の大きさは、使用応じて適宜決定されるが、平面形状として、四角形での一片の長さが、5〜1000μm、特に幅50〜300μmが望ましい。その他の形状の物は、このような四角形と同様の面積になるような大きさが好ましい。
凹部の間隔も目的に応じて適宜使用されるが、転写物を印刷対象(紙など)等の転写基材に均一に塗布する場合や粘着剤を塗布対象(プラスチックフィルムなど)等の転写基材に均一に塗布する場合、その箇所の対応した凹版における凹部の間隔は、1〜30μm、特に幅5〜20μmが望ましい。
転写物を凹部に均一に充填する場合に使用されるブレード又はスキージの移動方向は、凹部を隔てる相対的に凸部に引っかかりにくい方向が適宜選ばれるが、例えば、凹部の平面図形が四角形のような図形であれば、その辺に対してブレード又はスキージの移動方向が45〜60度になるようにすることが好ましい。
Here, the size of the recess is appropriately determined depending on the use, but as a planar shape, the length of a square piece is preferably 5 to 1000 μm, and particularly preferably 50 to 300 μm in width. Other shaped objects are preferably sized so as to have the same area as such a square.
The interval between the recesses is also appropriately used according to the purpose. However, when the transfer product is uniformly applied to a transfer substrate such as paper (paper) or the like, or the transfer substrate such as adhesive (plastic film or the like) is applied. When the coating is uniformly applied, the interval between the concave portions in the corresponding intaglio at the location is preferably 1 to 30 μm, particularly preferably 5 to 20 μm in width.
The moving direction of the blade or squeegee used for uniformly filling the concave portion with the transferred material is appropriately selected such that it is relatively difficult to catch the convex portion separating the concave portion. If it is a simple figure, it is preferable that the moving direction of the blade or squeegee is 45 to 60 degrees with respect to the side.

上記の凹版用基材の形状としては、シート状、プレート状、ロール状等がある。ロール状の場合は、ロール状それ自体とシート状、プレート状のものを回転体(ロール)に取り付けたものであってもよい。   Examples of the shape of the intaglio substrate include a sheet shape, a plate shape, and a roll shape. In the case of a roll, the roll itself, a sheet, or a plate may be attached to a rotating body (roll).

本発明における凹版用基材に用いられる材料は、鉄、アルミニウム、ステンレス鋼、クロムまたはニッケルめっきされた鉄、チタン、チタンをライニングした材料、ニッケルなどの材料からなることが特に好ましい。   The material used for the intaglio substrate in the present invention is particularly preferably made of iron, aluminum, stainless steel, chromium or nickel plated iron, titanium, titanium-lined material, nickel or the like.

As a method for forming a DLC thin film, dry deposition such as a vacuum deposition method, a sputtering method, an ion plating method, an arc discharge method, a physical vapor deposition method such as an ionization deposition method, a chemical vapor deposition method such as a plasma CVD method, etc. Although a method can be adopted, a plasma CVD method using a high frequency or pulse discharge in which the film formation temperature can be controlled from room temperature is particularly preferable.
In order to form the DLC thin film by the plasma CVD method, a hydrocarbon-based gas is preferably used as a carbon source as a raw material. For example, alkane gases such as methane, ethane, propane, butane, pentane, hexane, alkene gases such as ethylene, propylene, butene, pentene, alkadiene gases such as pentadiene, butadiene, acetylene, methylacetylene, etc. Alkyne gases, aromatic hydrocarbon gases such as benzene, toluene, xylene, indene, naphthalene and phenanthrene, cycloalkane gases such as cyclopropane and cyclohexane, cycloalkene gases such as cyclopentene and cyclohexene, methanol And alcohol gases such as ethanol, ketone gases such as acetone and methyl ethyl ketone, and aldehyde gases such as methanal and ethanal. The said gas may be used independently and may use 2 or more types together.

Further, these source gases may contain a rare gas. The rare gas is a gas composed of an element belonging to Group 0 of the periodic table, and examples thereof include helium, argon, neon, and xenon. These rare gases may be used alone or in combination of two or more.

膜は、その全体を、上述した絶縁性のDLC薄膜によって形成してもよいが、当該DLC薄膜の、金属板等の凹版用基材に対する密着性を向上させて、膜の耐久性をさらに向上させるためには、この両者の間に、Ti、Cr、W、Siもしくはそれらの窒化物又は炭化物から選ばれる一種以上の成分又はその他よりなる中間層を介挿することが好ましい。
上記SiまたはSiCの薄膜は、例えば、ステンレス鋼などの金属との密着性に優れる上、その上に積層する絶縁性のDLC薄との界面においてSiCを形成して、当該DLC膜の密着性を向上させる効果を有している。
中間層は、前記したようなドライコーティング法により形成させることができる。
中間層の厚みは、1μm以下であることが好ましく、生産性を考慮すると0.5μm以下であることが更に好ましい。1μm以上コーティングするには、コーティング時間が長くなると共に、コーティング膜の内部応力が大きくなるため適さない。
The film may be entirely formed of the insulating DLC thin film described above, but the adhesion of the DLC thin film to an intaglio substrate such as a metal plate is improved to further improve the durability of the film. In order to achieve this, it is preferable to insert an intermediate layer composed of at least one component selected from Ti, Cr, W, Si, nitrides or carbides thereof, or the like, between the two.
The Si or SiC thin film has excellent adhesion to, for example, a metal such as stainless steel, and forms SiC at the interface with the insulating DLC thin film laminated thereon, thereby improving the adhesion of the DLC film. Has the effect of improving.
The intermediate layer can be formed by the dry coating method as described above.
The thickness of the intermediate layer is preferably 1 μm or less, and more preferably 0.5 μm or less in consideration of productivity. A coating of 1 μm or more is not suitable because the coating time becomes long and the internal stress of the coating film increases.

膜をAl、SiOのような無機材料で形成する場合にも、スパッタリング法、イオンプレーティング法といった物理的気相成長法やプラズマCVDといった化学気相成長法を用いることができる。例えばスパッタリング法で形成する場合には、ターゲットをSiまたはAlにして反応性ガスとして酸素、窒素などの導入することでSiO、Siなどの酸化物、窒化物を成膜することができる。また、イオンプレーティング法を用いる場合にはSiやAlを原料とし、電子ビームをこれらに照射することで蒸発させ、基板に成膜することができる。その際に、酸素、窒素、アセチレンといった反応性ガスを導入することで酸化物、窒化物、炭化物を成膜することができる。
また、CVD法で成膜する場合には金属塩化物、金属水素化物、有機金属化合物などのような化合物ガスを原料とし、それらの化学反応を利用して成膜することでできる。酸化シリコンのCVDは、例えばTEOS、オゾンを用いたプラズマCVDで行える。窒化シリコンのCVDは、例えばアンモニアとシランを用いたプラズマCVDで行える。
Even when the film is formed of an inorganic material such as Al 2 O 3 or SiO 2 , a physical vapor deposition method such as a sputtering method or an ion plating method or a chemical vapor deposition method such as plasma CVD can be used. For example, in the case of forming by sputtering, an oxide or nitride such as SiO 2 or Si 3 N 4 can be formed by introducing Si or Al as a target and introducing oxygen, nitrogen or the like as a reactive gas. it can. In the case of using the ion plating method, Si or Al can be used as a raw material, and an electron beam can be irradiated to evaporate to form a film on the substrate. At that time, an oxide, nitride, or carbide film can be formed by introducing a reactive gas such as oxygen, nitrogen, or acetylene.
In the case of forming a film by the CVD method, the film can be formed by using a chemical gas such as a metal chloride, a metal hydride, an organometallic compound, etc. as a raw material. The CVD of silicon oxide can be performed by plasma CVD using, for example, TEOS or ozone. The CVD of silicon nitride can be performed by plasma CVD using ammonia and silane, for example.

上記の凹部は、凹部に貯留された転写物が転写されたときに転写基材上で一定の模様(均一で一様な膜を含む)になるような潜像が描かれるように多数の凹部からなるものであることが好ましい。
The method for producing an intaglio plate in the present invention includes a step of forming a film on the surface of the intaglio substrate so that a recess is formed.
This step is a step (A) of forming a removable convex pattern on the surface of the intaglio substrate,
(B) including a step of forming a film on the surface of the intaglio substrate on which a removable convex pattern is formed, and (C) a step of removing the convex pattern.
The above-mentioned concave portions have a large number of concave portions so that a latent image is drawn on the transfer base material when the transferred material stored in the concave portions is transferred. It is preferable that it consists of.

上記(A)凹版用基材の表面に、除去可能な凸状のパターンを形成する工程は、フォトリソグラフ法を利用して、レジストパターンを形成する方法を利用することができる。
この方法は、

The step of forming a removable convex pattern on the surface of the (A) intaglio substrate can utilize a method of forming a resist pattern using a photolithographic method.
This method
(A-1) a step of forming a photosensitive resist layer on the intaglio substrate,
(A-2) exposing the photosensitive resist layer to a desired latent image (latent image pattern) composed of a concave portion for holding ink with laser light or ultraviolet rays through a mask; and (a-3) photosensitivity after exposure. A step of developing the resist layer.

また、上記(A)凹版用基材の表面に、除去可能な凸状のパターンを形成する工程は、
(b−1)凹版用基材の上に樹脂層を形成する工程、
(b−2)樹脂層をレーザ光により昇華させ、インクを保持する凹部からなる所望の潜像(潜像パターン)を形成する工程

In addition, the step of forming a removable convex pattern on the surface of the (A) intaglio substrate,
(B-1) forming a resin layer on the intaglio substrate,
(B-2) including a step of sublimating the resin layer with a laser beam to form a desired latent image (latent image pattern) including a concave portion for holding ink.

感光性レジストとしては、よく知られたネガ型レジスト(光が照射された部分が硬化する)を使用することができる。また、感光性レジストとしてはポジ型レジストを用いることができる。   As the photosensitive resist, a well-known negative resist (a portion irradiated with light is cured) can be used. Further, a positive resist can be used as the photosensitive resist.

具体的方法として、凹版用基材上にドライフィルムレジスト(感光性樹脂層)をラミネートし、又は液状レジストを塗布した後に、レーザ光露光またはマスクを装着して紫外線露光することにより、凸状パターンとして残存させる部分を硬化状態に、不要部を現像可能状態とし、不要部を現像して除去することにより形成することができる。また、凸状パターンは、凹版用基材に液状レジストを塗布した後に溶剤を乾燥するかあるいは仮硬化させた後、レーザ光露光またはマスクを装着して露光することにより、凸状パターンとして残存させる部分を硬化状態に、不要部を現像可能状態とし、不要部を現像して除去することにより形成することもできる。液状レジストは、スプレー、ディスペンサー、ディッピング、ロール、スピンコート等により塗布できる。   As a specific method, a convex film pattern is formed by laminating a dry film resist (photosensitive resin layer) on a base for intaglio, or applying a liquid resist, and then exposing to laser light or wearing a mask and exposing to ultraviolet rays. The remaining portion can be cured, the unnecessary portion can be developed, and the unnecessary portion can be developed and removed. In addition, the convex pattern is left as a convex pattern by applying a liquid resist to the intaglio substrate and then drying or pre-curing the solvent, followed by laser light exposure or wearing a mask and exposing. It can also be formed by setting the part in a cured state, making the unnecessary part developable, and developing and removing the unnecessary part. The liquid resist can be applied by spraying, dispenser, dipping, roll, spin coating or the like.

上記において、光硬化性樹脂にマスクを介して又は介さずして活性エネルギー線を照射することでパターニングできればその態様は問わない。
導電性基材のサイズが大きい場合などはドライフィルムレジストを用いる方法が生産性の観点からは好ましく、凹版用基材がロールなどの場合は、液状レジストを塗布した後にマスクを介さずにレーザ光などで直接に露光する方法が好ましい。
ここで、凹版用基材の全面にあらかじめDLC又は無機材料の層を形成し、これを改めて凹版用基材として使用することができる。これにより、凹部の底部もDLC又は無機材料で覆われることになり、特に耐薬品性の向上が図れる。
In the above, as long as patterning can be performed by irradiating the photocurable resin with active energy rays with or without a mask, the mode is not limited.
When the size of the conductive substrate is large, a method using a dry film resist is preferable from the viewpoint of productivity, and when the intaglio substrate is a roll or the like, laser light is applied without applying a mask after applying the liquid resist. For example, a direct exposure method is preferable.
Here, a layer of DLC or an inorganic material is formed in advance on the entire surface of the intaglio substrate, and this can be used again as the intaglio substrate. Thereby, the bottom part of a recessed part will also be covered with DLC or an inorganic material, and especially a chemical-resistant improvement can be aimed at.

本発明における凹版の製造方法の一例を図面を用いて説明する。
図3は、凹版の製造方法を示す工程の一例を断面図で示したものである。
An example of a method for producing an intaglio plate according to the present invention will be described with reference to the drawings.
FIG. 3 is a sectional view showing an example of a process showing a method for manufacturing an intaglio.

凹版用基材2の上に感光性レジスト層(感光性樹脂層)5形成されている(図3(a))。この積層物の感光性レジスト層(感光性樹脂層)5に対し、フォトリソグラフ法を適用して感光性レジスト層5をパターン化する(図3(b))。パターン化は、パターンが形成されたフォトマスクを感光性レジスト層5の上に載置し、露光した後、現像して感光性レジスト層5の不要部を除去して凸状パターン6を残すことにより行われる。凸状パターンは、凹版用基材2上の凹部4に対応するよう考慮される。   A photosensitive resist layer (photosensitive resin layer) 5 is formed on the intaglio substrate 2 (FIG. 3A). The photosensitive resist layer 5 is patterned by applying a photolithographic method to the photosensitive resist layer (photosensitive resin layer) 5 of the laminate (FIG. 3B). For patterning, a photomask on which a pattern is formed is placed on the photosensitive resist layer 5, exposed, and then developed to remove unnecessary portions of the photosensitive resist layer 5 to leave the convex pattern 6. Is done. The convex pattern is considered to correspond to the concave portion 4 on the intaglio substrate 2.

この時、凸状パターン6の断面形状において、凸状パターン幅の最大値dは、凸状パターンと凹版用基材2に接する幅dと等しいか大きくしなければならない。これは、形成される密着性の良い膜の凹部幅はdによって決定されるからである。ここで、凸状パターン6の断面形状で、凸状パターン幅の最大値dが凸状パターンと凹版用基材2に接する幅dと等しいか大きくする方法としては、凸状パターン6の現像時にオーバ現像とするか、形状がアンダカットとなる特性を有するレジストを使用すれば良い。dは凸部の上部で実現されていることが好ましい。
除去可能な凸部のパターン形状は、凹部の形状に対応づけられる。平面形状として、四角形での一片の長さが、3〜1000μm、特に幅50〜300μmが望ましい。その他の形状の物は、このような四角形と同様の面積になるような大きさが好ましい。凸部の間隔も目的に応じて適宜使用されるが、転写物を印刷対象、粘着剤塗布の対象などの転写基材に均一に塗布する場合、その箇所の対応した凸部の間隔は、1〜30μm、特に幅5〜20μmが望ましい。
At this time, in the cross-sectional shape of the convex pattern 6, the maximum value d 1 of the convex pattern width must be equal to or larger than the width d 0 in contact with the convex pattern and the intaglio substrate 2. This is because the recess width of the film having good adhesion is determined by d 1 . Here, as a method for increasing the width d 0 of the convex pattern width in contact with the convex pattern and the intaglio substrate 2 in the sectional shape of the convex pattern 6, the convex pattern width maximum value d 1 is as follows. It is sufficient to use a resist having a characteristic of over-development during development or having an undercut shape. d 1 is preferably is realized at the top of the convex portion.
The pattern shape of the removable convex portion is associated with the shape of the concave portion. As the planar shape, the length of a square piece is preferably 3 to 1000 μm, and particularly preferably 50 to 300 μm in width. Other shaped objects are preferably sized so as to have the same area as such a square. The interval between the convex portions is also appropriately used according to the purpose. However, when the transfer product is uniformly applied to a transfer substrate such as a printing target or an adhesive application target, the interval between the corresponding convex portions is 1 A width of ˜30 μm, particularly a width of 5 to 20 μm is desirable.

ついで、凸状パターン6を有する凹版用基材2の表面に膜7を形成する(図3(c))。膜の形成方法は、前記したとおりである。
さらに、膜7が付いている状態で、凸状パターンを除去する(図3(d))。
膜の付着しているレジストの除去には、市販のレジスト剥離液や無機、有機アルカリ、有機溶剤などを用いることができる。また、パターンを形成するのに使用したレジストに対応する専用の剥離液があれば、それを用いることもできる。
剥離の方法としては、例えば薬液に浸漬することでレジストを膨潤、破壊あるいは溶解させた後これを除去することが可能である。液をレジストに十分含浸させるために超音波、加熱、撹拌等の手法を併用しても良い。また、剥離を促進するためにシャワー、噴流等で液をあてることもできるし、柔らかい布や綿棒などでこすることもできる。
また、膜の耐熱性が十分高い場合には高温で焼成してレジストを炭化させて除去することもできるし、レーザを照射して焼き飛ばす、といった方法も利用できる。
剥離液としては、例えば、3%NaOH溶液を用い、剥離法としてシャワーや浸漬が適用できる。
Next, a film 7 is formed on the surface of the intaglio substrate 2 having the convex pattern 6 (FIG. 3C). The method for forming the film is as described above.
Further, the convex pattern is removed with the film 7 attached (FIG. 3D).
A commercially available resist stripping solution, inorganic, organic alkali, organic solvent, or the like can be used to remove the resist to which the film is attached. In addition, if there is a dedicated stripping solution corresponding to the resist used to form the pattern, it can be used.
As a peeling method, for example, it is possible to remove the resist after it has been swelled, broken or dissolved by immersion in a chemical solution. In order to sufficiently impregnate the resist with the solution, techniques such as ultrasonic waves, heating, and stirring may be used in combination. In addition, the liquid can be applied with a shower, a jet or the like in order to promote peeling, and can be rubbed with a soft cloth or cotton swab.
In addition, when the heat resistance of the film is sufficiently high, a method of baking at a high temperature to carbonize the resist and removing it, or irradiating with a laser to burn off can be used.
As the stripping solution, for example, a 3% NaOH solution is used, and showering or dipping can be applied as the stripping method.

凹版用基材2上に形成される膜と、凸状パターン6の側面に形成される膜とでは、性質が異なる。すなわち、硬度が、前者の方が後者より大きい。このため、凸部パターンを除去するとき、膜は、この境界で分離され、その結果、凹部の側面の傾斜角αは、角度で30度以上90度未満が好ましく、30度以上60度以下が特に好ましく、DLC膜をプラズマCVDで作製する場合、ほぼ45〜60度に制御することが容易になる。すなわち、凹部4は、開口方向に向かって幅広になるように形成される。
凹版用基材2上に形成される膜と、凸状パターン6の側面に形成される膜とでは、性質が異なる。これは、膜の形成において、凹版用基材はレジストの影にならないので、凹版用基材上の膜は性質が均一である。これに対し、凸状パターンの側面への膜の形成は、凸状パターンの側面が凹版用基材上の膜厚方向に対し角度を有しているため、形成される膜(特にDLC膜)は、凹版用基材上の膜と同じ特性(例えば、同じ硬度)の膜が得られない。このような異質な膜の接触面においては、膜の成長に伴い膜の境界面が形成され、しかも、その境界面は膜の成長面であることから、滑らかである。このため、凸部パターンを除去するとき、膜(特にDLC膜)は、この境界で容易に分離される。さらに、この境界面、即ち、凹部側面となる傾斜角αは、凹版用基材上の膜厚方向に対し凸部パターンの側面で膜の成長が遅れるため、結果として、境界面の傾斜角は、上記のように制御される。
The film formed on the intaglio substrate 2 and the film formed on the side surface of the convex pattern 6 have different properties. That is, the hardness of the former is greater than the latter. For this reason, when the convex pattern is removed, the film is separated at this boundary. As a result, the inclination angle α of the side surface of the concave is preferably 30 degrees or more and less than 90 degrees, and preferably 30 degrees or more and 60 degrees or less. It is particularly preferable that when the DLC film is formed by plasma CVD, it becomes easy to control at approximately 45 to 60 degrees. That is, the concave portion 4 is formed so as to become wider toward the opening direction.
The film formed on the intaglio substrate 2 and the film formed on the side surface of the convex pattern 6 have different properties. This is because in the formation of the film, the intaglio substrate does not become a shadow of the resist, so the film on the intaglio substrate is uniform in nature. On the other hand, the film is formed on the side surface of the convex pattern because the side surface of the convex pattern has an angle with respect to the film thickness direction on the intaglio substrate. Cannot obtain a film having the same characteristics (for example, the same hardness) as the film on the intaglio substrate. In such a heterogeneous film contact surface, a film boundary surface is formed as the film grows, and since the boundary surface is a film growth surface, it is smooth. For this reason, when removing the convex pattern, the film (particularly the DLC film) is easily separated at this boundary. Further, the inclination angle α which becomes the boundary surface, that is, the side surface of the concave portion is that the growth of the film is delayed on the side surface of the convex portion pattern with respect to the film thickness direction on the intaglio substrate. , Controlled as described above.

本発明において凹版用基材上に形成された膜の硬度は、10〜40GPaであることが好ましい。硬度が10GPa未満の膜は軟質であり、凹版の繰り返し使用における耐久性が低くなる。硬度が40GPa以上では、凹版を折り曲げ等の加工をした際に基材の変形に追随できなくなり、膜にひびや割れが発生するので好ましくない。より好ましくは12〜30GPaである。
これに対して、凸部パターンの側面に形成される膜の硬度は1〜15GPaであることが好ましい。凸部パターンの側面に形成される膜は、少なくとも凹版用基材上に形成される膜の硬度よりも低くなるように形成することが好ましい。そうすることにより両者間に境界面が形成され、後の膜の付着した凸部パターンを剥離する工程を経た後に、幅広な凹部が形成されることになる。凸部パターンの側面に形成される膜の硬度は1〜10GPaであることがより好ましい。
膜の硬度は、ナノインデンテーション法を用いて測定することができる。ナノインデンテーション法とは、先端形状がダイヤモンドチップから成る正三角錐(バーコビッチ型)の圧子を薄膜や材料の表面に押込み、そのときの圧子にかかる荷重と圧子の下の射影面積から硬度を求める。ナノインデンテーション法による測定として、ナノインデンターという装置が市販されている。凹版用基材上に形成された膜の硬度はそのまま凹版用基材上から圧子を押し込んで測定することができる。また、凸部パターンの側面に形成される膜の硬度を測定するためには、膜を形成後に、凸部パターンを有する凹版用基材の一部を切り取って樹脂で注型し、断面から凸部パターンの側面に形成された膜に圧子を押し込んで測定することができる。通常ナノインデンテーション法では圧子に1〜100mNの微少荷重をかけて硬度測定を行うが、本発明では3mNの荷重で10秒間負荷をかけて測定した値を硬度の値として記載している。
このようにして、凹版1を作製することができる。
In the present invention, the hardness of the film formed on the intaglio substrate is preferably 10 to 40 GPa. A film having a hardness of less than 10 GPa is soft and has a low durability in repeated use of the intaglio. When the hardness is 40 GPa or more, it is not preferable because when the intaglio is processed such as bending, it cannot follow the deformation of the base material, and the film is cracked or cracked. More preferably, it is 12-30 GPa.
On the other hand, the hardness of the film formed on the side surface of the convex pattern is preferably 1 to 15 GPa. The film formed on the side surface of the convex pattern is preferably formed so as to be at least lower in hardness than the film formed on the intaglio substrate. By doing so, a boundary surface is formed between the two, and a wide concave portion is formed after a process of peeling the convex pattern to which the film is attached later. The hardness of the film formed on the side surface of the convex pattern is more preferably 1 to 10 GPa.
The hardness of the film can be measured using a nanoindentation method. In the nanoindentation method, a regular triangular pyramid (Berkovic type) indenter with a diamond tip is pressed into the surface of a thin film or material, and the hardness is obtained from the load applied to the indenter and the projected area under the indenter. As a measurement by the nanoindentation method, a device called a nanoindenter is commercially available. The hardness of the film formed on the intaglio substrate can be measured by pushing the indenter directly onto the intaglio substrate. In addition, in order to measure the hardness of the film formed on the side surface of the convex pattern, after forming the film, a part of the intaglio substrate having the convex pattern is cut out and cast with a resin, and the convex part is projected from the cross section. Measurement can be performed by pressing an indenter into the film formed on the side surface of the part pattern. Normally, in the nanoindentation method, the hardness is measured by applying a minute load of 1 to 100 mN to the indenter, but in the present invention, the value measured by applying a load of 3 mN for 10 seconds is described as the hardness value.
In this way, the intaglio 1 can be produced.

図4は、中間層を有する凹版とその前駆体の断面図を示す。
凸状パターン6が形成された凹版用基材2の表面に、膜7を形成する前に、中間層8を形成することが好ましい(図4(c′))。中間層としては、前記したものが使用でき、その形成方法も前記したとおりである。この例において、得られる凹版は、凹部4の底部は、凹版用基材2が露出しており、それ以外では、中間層8の上に膜7が形成されている(図4(d′))。
FIG. 4 shows a sectional view of an intaglio having an intermediate layer and its precursor.
Before forming the film 7 on the surface of the intaglio substrate 2 on which the convex pattern 6 is formed, it is preferable to form the intermediate layer 8 (FIG. 4 (c ′)). As the intermediate layer, those described above can be used, and the formation method is also as described above. In this example, the intaglio plate obtained is such that the intaglio substrate 2 is exposed at the bottom of the recess 4, and a film 7 is formed on the intermediate layer 8 in other cases (FIG. 4D). ).

本発明の凹版を用いてグラビア印刷や粘着剤塗布する場合は、グラビアロール周面に印刷インクや粘着剤を塗布し、ドクターブレードによりグラビアロール周面を摺擦し、凹部以外の凸部のインクや粘着剤を掻き落として、グラビアロールに用紙等の転写基材を圧着し、凹部に貯留したインクや粘着剤を転写基材に転写することにより行うことができる。このような方法は、転写基材が可とう性のものに適している。転写物はレジストであってもよい。
ガラス基板等の基材へのカラーフィルタ用のインク又は着色レジストの転写塗布や銅張積層板等の基材にレジストの転写塗布を行う場合は、凹版の凹部にカラーフィルタ用のインク又は着色レジストあるいはレジストを適正量貯留し、それをスタンプやロールといった転写機器に写し取って、さらに、ガラス基板、銅張積層板等の基材に転写する方法により行うことができる。このような方法は、特に、転写基材が剛直なものに適している。このような方法は、有機ELや無機EL等の発光物質を含む印刷インクの基材への転写塗布にも利用することができる。
When applying gravure printing or pressure-sensitive adhesive using the intaglio plate of the present invention, apply printing ink or pressure-sensitive adhesive on the surface of the gravure roll, rub the surface of the gravure roll with a doctor blade, and ink on the convex portions other than the concave portions. Or the adhesive is scraped off, a transfer substrate such as paper is pressure-bonded to the gravure roll, and the ink or adhesive stored in the recesses is transferred to the transfer substrate. Such a method is suitable for a flexible transfer substrate. The transferred material may be a resist.
When performing transfer coating of color filter ink or colored resist onto a substrate such as a glass substrate or transfer of resist onto a substrate such as a copper-clad laminate, the color filter ink or colored resist is formed in the concave portion of the intaglio plate. Alternatively, an appropriate amount of resist can be stored, transferred to a transfer device such as a stamp or a roll, and further transferred to a substrate such as a glass substrate or a copper clad laminate. Such a method is particularly suitable for a rigid transfer substrate.
