Description

【0001】
【発明の属する技術分野】
本発明は、オフセット印刷による電極パターンの形成方法に関する。
【0002】
【従来の技術】
従来、微細な電極パターンの形成方法として、ガラス基板上に導電性粉体を含有するパターン形成用ペーストを用いてスクリーン印刷法やフォトリソグラフィー法によりパターンを形成した後、焼成して電極パターンを形成する方法がある。しかし、スクリーン印刷法による電極パターンの形成には、スクリーン印刷版を構成するメッシュ材料の伸びによる印刷精度の限界があり、また、形成したパターンにメッシュ目が生じたりパターンの滲みが発生し、電極パターンのエッジ精度が低いという問題がある。また、フォトリソグラフィー法には、高精度の電極パターンの形成が可能であるものの、製造工程が複雑であり、材料ロスが多く、製造コストの低減に限界があった。
【0003】
このため、工程が簡単で量産性を有するオフセット印刷法を用いることによって微細電極パターンの形成の低コスト化が試みられている。このオフセット印刷法では、導電性粉体を含有する導体インキを凹版或いは平版の印刷版に供給し、印刷版上のインキパターンをブランケットを介して電極被形成物に転移させ、その後、焼成して有機成分を分解、揮発することにより電極パターンが形成される。
【0004】
オフセット印刷法は、スクリーン印刷法に比べて精度の高い電極パターンの形成が可能であり、また、フォトリソグラフィ法に比べてインキ使用量が少ないという利点がある。更にフォトリソグラフィ法では、焼成して形成された電極パターンの幅方向の断面形状は矩形となり、例えば、プラズマディスプレイパネルの電極パターンのように、その上から誘電体層を形成する場合、電極のエッジが誘電体層を突き破って露出してしまうことがおこる可能性があるのに対して、オフセット印刷法で得られた電極パターンの幅方向の断面形状は蒲鉾形なので、前記のような電極のエッジに起因するトラブルはおこらない。
【0005】
【発明が解決しようとする課題】
しかしながら、通常、オフセット印刷によりガラス基板上に約5〜30μm 程度の厚盛り印刷を行うと図1に略図示するように基板1上に形成した印刷パターン2の輪郭からインキがひげ状に飛び出すひげ欠陥3が生じる。これはインキを版に充填するとき、又はブランケットが版からインキを受理するとき又は転移時に、ガラス基板とブランケットとの摩擦によって発生する静電気が凝集破壊面や突起のあるインキ部を引き付けることなどによりおこるものである。
【0006】
本発明の目的は、オフセット印刷により電極パターンを印刷するときに生じるひげ欠陥を解消したオフセット印刷による電極パターンの形成方法を提供することである。
【0007】
【課題を解決するための手段】
本発明者は、ひげ欠陥をなくすべく研究の結果、導電性粉体として少なくとも2種類以上の粒子形状の異なる導電性粉体の混合物を含み、且つ該混合物中に5〜40質量百分率の粒子形状がフレーク状であるフレーク状導電性粉体を含む導体インキを用いることにより、ひげ欠陥は少なくなること、及び上記の導体インキを表面抵抗が1×1011Ω以下になるように表面処理した基板と併用することによりひげ欠陥の発生は劇的に少なくなることを見出し、本発明を完成した。
【0008】
請求項1に記載の発明は、本発明の課題を解決するもので、導電性粉体と焼成除去可能な有機成分を少なくとも含有する導体インキを用いて基板上にオフセット印刷により5〜30μmの厚盛りで電極パターンを印刷した後に焼成する電極パターンの形成方法であって、導電性粉体として少なくとも2種類以上の粒子形状の異なる導電性粉体の混合物を含み、且つ該混合物中に20〜30質量百分率の粒子形状がフレーク状であるフレーク状導電性粉体を含んでおり、フレーク状導電性粉体はマイクロトラック法によるD50値の粒径が2〜15μmの範囲にあり、フレーク状導電性粉体以外の導電性粉体はマイクロトラック法によるD50値の粒径が0.2〜2.0μmの範囲にある導体インキを用いることを特徴とする。
【0011】
請求項に記載の発明は、請求項1に記載のオフセット印刷による電極パターンの形成方法において、基板として、焼成除去が可能な材料により表面抵抗が1×1011Ω/□以下になるように帯電防止処理した基板を用いることを特徴とする。
【0012】
そして、帯電防止処理した基板として基板上に導電性高分子を含む樹脂液を塗布後乾燥して帯電防止層を形成してなるものを用いることが最も好ましい。
【0013】
【発明の実施の形態】
以下本発明のオフセット印刷による電極パターンの形成方法について具体的に説明する。
先ず導電性粉体として少なくとも2種類以上の粒子形状の異なる導電性粉体の混合物を含み、且つ該混合物中に5〜40質量百分率粒子形状がフレーク状であるフレーク状導電性粉体を含む導体インキを作製する。この導体インキを用いてガラス基板上にオフセット印刷によりプラズマディスプレイパネルの電極パターン等の微細パターンを厚盛り印刷した後に焼成する。

ガラス基板に、イオン(カリウム、ナトリウム、塩素等)が含まれていないものであって、焼成後に残カーボンはなくまたはガラス化し、表面電位が1×1011Ω以下の層を形成する液を塗布した後、乾燥して帯電防止層を形成する。具体的には例えば丸菱油化工業(株)製導電性高分子PPY−14(ポリピロールを水系ディスパージョンにしたもの/エポキシ系架橋剤/アクリル系樹脂からなる導電性高分子を含む樹脂液をガラス基板にスピンナーにより塗布後160℃で2分間乾燥して帯電防止層を形成してなるものが適している。その他に例えばコルコート(株)製N103Xのようなシロキサン系帯電防止層、乾燥後プラズマディスプレイパネル(PDP)用下地層(鉛系ガラスフリットを主成分とするカラスペースト、樹脂、セルロース系材料等)でも可であるが上記導電性高分子を含有する帯電防止層が最も効果がある。尚前記導電性高分子を含有する帯電防止層中に含まれる導電性高分子は、焼結後は導電性の機能は低下せしめられるのでガラス基板の絶縁性を損なうものではない。
【0020】

BACKGROUND OF THE INVENTION
The present invention relates to a method for forming an electrode pattern by offset printing.
[0002]
[Prior art]
Conventionally, as a method for forming a fine electrode pattern, a pattern is formed by screen printing or photolithography using a paste for pattern formation containing conductive powder on a glass substrate, and then the electrode pattern is formed by firing. There is a way to do it. However, the formation of the electrode pattern by the screen printing method has a limit of printing accuracy due to the elongation of the mesh material constituting the screen printing plate, and the mesh formed in the formed pattern or the bleeding of the pattern occurs. There is a problem that the edge accuracy of the pattern is low. In addition, although the photolithography method can form an electrode pattern with high accuracy, the manufacturing process is complicated, there are many material losses, and there is a limit to the reduction in manufacturing cost.
[0003]
For this reason, it has been attempted to reduce the cost of forming a fine electrode pattern by using an offset printing method that has a simple process and is mass-productive. In this offset printing method, a conductive ink containing conductive powder is supplied to an intaglio or lithographic printing plate, the ink pattern on the printing plate is transferred to an electrode formation through a blanket, and then fired. An electrode pattern is formed by decomposing and volatilizing organic components.
[0004]
The offset printing method can form an electrode pattern with higher accuracy than the screen printing method, and has an advantage that the amount of ink used is smaller than that of the photolithography method. Further, in the photolithography method, the cross-sectional shape in the width direction of the electrode pattern formed by baking is rectangular. For example, when forming a dielectric layer from the top like the electrode pattern of a plasma display panel, the edge of the electrode May be exposed through the dielectric layer, whereas the cross-sectional shape in the width direction of the electrode pattern obtained by the offset printing method is saddle-shaped. Troubles caused by will not occur.
[0005]
[Problems to be solved by the invention]
However, generally, when thick printing of about 5 to 30 μm is performed on a glass substrate by offset printing, the whiskers in which ink protrudes in a whisker shape from the outline of the printed pattern 2 formed on the substrate 1 as schematically shown in FIG. Defect 3 occurs. This is because when the ink is filled into the plate, or when the blanket receives ink from the plate or at the time of transfer, static electricity generated by friction between the glass substrate and the blanket attracts the cohesive failure surface or the ink part with protrusions. It happens.
[0006]
The objective of this invention is providing the formation method of the electrode pattern by offset printing which eliminated the whisker defect which arises when printing an electrode pattern by offset printing.
[0007]
[Means for Solving the Problems]
As a result of research to eliminate whisker defects, the present inventor includes a mixture of at least two kinds of conductive powders having different particle shapes as the conductive powder, and 5 to 40 mass percent of the particle shape in the mixture. By using a conductor ink containing flaky conductive powder having a flake shape, the whisker defects are reduced, and the above-described conductor ink is surface-treated so that the surface resistance is 1 × 10 11 Ω or less It was found that the occurrence of whisker defects dramatically decreases when used together with the present invention, and the present invention has been completed.
[0008]
The invention described in claim 1 solves the problem of the present invention, and is 5 to 30 μm thick by offset printing on a substrate using a conductive ink containing at least conductive powder and an organic component that can be removed by baking. A method of forming an electrode pattern, which is fired after printing an electrode pattern on a scale, comprising a mixture of at least two types of conductive powders having different particle shapes as the conductive powder, and 20-30 in the mixture The flake-shaped conductive powder contains a flake-shaped conductive powder having a flake-like particle shape with a mass percentage, and the particle size of D50 value by microtrack method is in the range of 2 to 15 μm. Conductive powder other than the conductive powder is characterized by using a conductive ink having a D50 particle size in the range of 0.2 to 2.0 μm by the microtrack method.
[0011]
According to a second aspect of the present invention, in the method for forming an electrode pattern by offset printing according to the first aspect, the substrate has a surface resistance of 1 × 10 11 Ω / □ or less by a material that can be removed by firing. It is use an antistatic-treated substrate, characterized in.
[0012]
And, as a substrate on which antistatic treatment, it is most preferable to use one made by forming an antistatic layer of the resin solution was dried after coating containing a conductive polymer on a substrate.
[0013]

Using this conductive ink, a fine pattern such as an electrode pattern of a plasma display panel is thickly printed on a glass substrate by offset printing, and then fired.
