Description

本発明は、潜像形成用組成物に関する。詳しくは親液部と撥液部とを形成可能な硬化塗膜を提供するための潜像形成用組成物に関する。 The present invention relates to a composition for forming a latent image. More specifically, the present invention relates to a composition for forming a latent image for providing a cured coating film capable of forming a parent liquid portion and a liquid repellent portion.

液晶ディスプレイ、携帯電話、タブレット等のモバイル情報機器、デジタルカメラ、有機ELディスプレイ、有機EL照明、センサー等の電子機器においては、小型化、薄型化に加え、さらなる高性能化が求められている。
これら電子機器の配線部位の形成には、光硬化性組成物の膜(レジスト前駆体膜)を用いる方法と用いない方法とがある。
光硬化性組成物を用いる方法には、光硬化性組成物の膜(レジスト前駆体膜)を絶縁性基材上に設ける場合と、銅箔等を全面に具備する基材上に設ける場合とがある。
前者の場合、光硬化性組成物の膜(レジスト前駆体膜)を絶縁性基材上に設けた後、パターン露光し、次いで未露光部をアルカリ水溶液等で除去し、前記除去部(硬化したレジストの設けられていない部分)に導電性材料を蒸着等して配線部位を形成する。配線部位形成後、必要に応じて硬化したレジストを除去したり、あるいはさらに熱硬化したりする。
後者の場合、光硬化性組成物の膜(レジスト前駆体膜)を銅箔等上に設けた後、パターン露光し、次いで未露光部をアルカリ水溶液等で除去した後、前記除去部(硬化したレジストの設けられていない部分)の銅箔等をエッチングで除去し、エッチング後、露光部に形成されていたレジスト部を除去することにより、露光パターンに応じた配線部位を形成する。
Mobile information devices such as liquid crystal displays, mobile phones and tablets, and electronic devices such as digital cameras, organic EL displays, organic EL lighting and sensors are required to have higher performance in addition to being smaller and thinner.
There are a method using a film (resist precursor film) of a photocurable composition and a method not using it to form a wiring portion of these electronic devices.
The method using the photocurable composition includes a case where a film of the photocurable composition (resist precursor film) is provided on an insulating base material and a case where a film of the photocurable composition is provided on a base material having a copper foil or the like on the entire surface. There is.
In the former case, a film of the photocurable composition (resist precursor film) is provided on the insulating base material, and then pattern exposure is performed, and then the unexposed portion is removed with an alkaline aqueous solution or the like, and the removed portion (cured) is removed. A wiring portion is formed by depositing a conductive material on the portion where the resist is not provided). After forming the wiring portion, the cured resist is removed or further thermosetting, if necessary.
In the latter case, a film of the photocurable composition (resist precursor film) is provided on a copper foil or the like, then pattern-exposed, and then the unexposed portion is removed with an alkaline aqueous solution or the like, and then the removed portion (cured). The copper foil or the like (the portion where the resist is not provided) is removed by etching, and after etching, the resist portion formed in the exposed portion is removed to form a wiring portion according to the exposure pattern.

一方、光硬化性組成物の膜(レジスト前駆体膜)を用いない方法の一種である印刷法は、基材に配線部位を直接印刷する方法であり、プリンテッドエレクトロニクス技術とも称され、サブトラクティブ法に比して大幅な工程の簡略化・大面積化・低コスト化が期待され、近年注目を集めている。 On the other hand, the printing method, which is a kind of method that does not use a film (resist precursor film) of a photocurable composition, is a method of directly printing a wiring portion on a substrate, which is also called printed electronics technology and is a subtractive method. It is expected to greatly simplify the process, increase the area, and reduce the cost compared to the method, and has been attracting attention in recent years.

インクジェットやスクリーン印刷、グラビア印刷、グラビアオフセット印刷等の従来印刷法は、基材上に直接所望パターンの配線を形成できることから、配線印刷技術の候補として挙げられてきた。しかし、高精細で複雑なパターン配線を形成するにあたり、印刷に使用するパターン形成材料が流動する結果、これらの濡れ広がりやにじみが生じるため、従来手法による微細パターンの形成には限界があった。 Conventional printing methods such as inkjet, screen printing, gravure printing, and gravure offset printing have been listed as candidates for wiring printing technology because they can form wiring of a desired pattern directly on a substrate. However, when forming a high-definition and complicated pattern wiring, as a result of the pattern forming material used for printing flowing, these wet spreads and bleeding occur, so that there is a limit to the formation of a fine pattern by the conventional method.

特許文献1には、塗膜の所定部分に放射線照射を行い、親液部と撥液部を有する基材を製造し、放射線照射部に形成された親液部に導電膜形成用の膜形成材料を塗布し、加熱して、パターンを形成する方法が記載されている(請求項1、10、図1〜5)。
特許文献2には、親水性感光樹脂層上に光を照射し、表面を変質させた後、変質した部位をフッ素化合物からなる液体または気体にさらすことにより光照射部位のみを撥液化し、親水性部(前記撥水化されたエッジ周辺部により区画されたパターン形状領域内)にインキ液を配置するパターン形成方法が記載されている(請求項1、図1)。
In Patent Document 1, a predetermined portion of the coating film is irradiated with radiation to produce a base material having a parent liquid portion and a liquid repellent portion, and a film for forming a conductive film is formed on the parent liquid portion formed in the radiation irradiation portion. A method of applying a material and heating to form a pattern is described (claims 1, 10, FIGS. 1 to 5).
According to Patent Document 2, the hydrophilic photosensitive resin layer is irradiated with light to alter the surface, and then the altered portion is exposed to a liquid or gas composed of a fluorine compound to make only the light-irradiated portion liquid-repellent and hydrophilic. A pattern forming method for arranging an ink liquid in a sex portion (inside a pattern shape region defined by the water-repellent edge peripheral portion) is described (claim 1, FIG. 1).

特開2016−087602号公報Japanese Unexamined Patent Publication No. 2016-087602 特開2014−004512号公報Japanese Unexamined Patent Publication No. 2014-004512

特許文献1記載の方法の場合、パターン形成材料の広がりやにじみを防ぐために、高い撥液能を有する塗膜を用い、放射線未照射部には高い撥液性を残し、放射線照射部を親液性とするためには、[A]アセタール結合を有する基またはケイ素原子を含む基から選ばれる少なくとも一つの基を有する重合体の利用が必要である。しかし、前記重合体[A]の製造は、多くの複雑な工程が必要である。さらに、前記アセタール結合を有する基が、フッ素原子を有する酸解離性基である場合、放射線照射部を親液性とする際、フッ素ガス及びフッ素系溶媒が発生するという懸念があった。 In the case of the method described in Patent Document 1, in order to prevent the pattern forming material from spreading and bleeding, a coating film having high liquid repellency is used, high liquid repellency is left in the non-irradiated portion, and the irradiated portion is a parent solution. In order to obtain the property, it is necessary to utilize a polymer having at least one group selected from the group having the [A] acetal bond or the group containing a silicon atom. However, the production of the polymer [A] requires many complicated steps. Further, when the group having an acetal bond is an acid dissociable group having a fluorine atom, there is a concern that fluorine gas and a fluorine-based solvent will be generated when the irradiation portion is made lyophilized.

また、特許文献2記載の方法は、プロセスが煩雑で時間を要する。さらに、光照射後にフッ素化合物からなる液体または気体による撥水化処理を必須とするので、前記処理剤のための特別な排気設備が必要となる。しかも、撥水化の程度は十分ではない。 Further, the method described in Patent Document 2 has a complicated process and takes time. Further, since water repellent treatment with a liquid or gas made of a fluorine compound is essential after light irradiation, special exhaust equipment for the treatment agent is required. Moreover, the degree of water repellency is not sufficient.

本発明の目的は、簡易な工程で、硬化塗膜形成後にフッ素系処理を行わずに、活性エネルギー線の照射のみで所望の部分の表面性状を親液性から撥液性へと変わり得る潜像形成用組成物を提供することにある。
また、本発明の目的は、上記潜像形成用組成物を用いて、基材上に親液部と撥液部とを有する潜像を形成し、該潜像上の親液部にインキを付着させ、高精細なパターンを形成することにある。
An object of the present invention is a latent process that can change the surface texture of a desired portion from liquid-repellent to liquid-repellent by simply irradiating with active energy rays without performing fluorine-based treatment after forming a cured coating film. The purpose is to provide an image-forming composition.
Further, an object of the present invention is to form a latent image having a parent liquid portion and a liquid repellent portion on a substrate by using the above-mentioned latent image forming composition, and apply ink to the parent liquid portion on the latent image. The purpose is to adhere and form a high-definition pattern.

本発明者は、前記課題を解決すべく鋭意検討した結果、基材上に親液性感光樹脂層を形成し、この親液性感光樹脂層に活性エネルギー線を選択的に照射して、照射部を撥液性に変じ、非照射部にインキ材料を付着させるという、簡単なプロセスで精度よくパターンを形成できることを見出し、以下の本発明に至った。

本発明で用いるカルボン酸の有機塩(C)は光の照射によって脱炭酸し、その結果、3つの遊離体を生成する。
スキームで示すと以下のスキーム1(ケトプロフェン類)、スキーム2(キサントン酢酸類)、スキーム3(チオキサントン酢酸類)及びスキーム4(ニトロフェニル酢酸類)のとおりである。
詳細なメカニズムは不明であるが、脱炭酸工程によって有機塩中に存在していた親液性発現に大きく寄与していると考えられるカルボキシレートアニオン(−COO)部位が失われ、中性化されたことにより、親液性が喪失したと考えられる。そのため、脱炭酸後は潜在していたフッ素系化合物の作用が結果として大きく働き、撥インキ性を発現するようになったものと考察している。

The schemes are as follows: Scheme 1 (ketoprofen), Scheme 2 (xanthone acetic acid), Scheme 3 (thioxanthone acetic acid) and Scheme 4 (nitrophenylacetic acid).
Although detailed mechanism is unknown, carboxylate anion is thought to contribute significantly to the lyophilic expression was present in the organic salt by decarboxylation step (-COO -) site is lost, neutralized It is probable that the positivity was lost due to this. Therefore, it is considered that the latent action of the fluorine-based compound after decarboxylation works greatly as a result, and the ink repellency is exhibited.

[Pattern formation method]
The pattern forming method of the present invention will be described in detail below.
At the same time, the laminate of the present invention, the method for producing the laminate, and the method for producing a latent image will be described.
The pattern forming method of the present invention includes the following [step 1], [step 2], and [step 3].
[Step 1]
As shown in FIG. 1, the cured coating film 2 can be formed by applying the above-mentioned latent image forming composition of the present invention to at least one surface of the base material 1 and heat-curing it. Alternatively, the latent image forming composition of the present invention is applied onto a peelable sheet to form an uncured thin film latent image forming composition, and then the uncured thin film latent image forming composition is formed. Can also be heat-cured to form a cured coating film 2 after being transferred onto the substrate 1. Since the cured coating film 2 has a high affinity with the ink described later, it is also referred to as a proinkable photosensitive resin layer.
Examples of the method of applying the latent image forming composition of the present invention to the base material 1 or the peelable sheet include spray coating, roll coating, spin coating, dipping and the like.
The film thickness of the ink-friendly photosensitive resin layer is preferably about 0.1 μm to 50 μm. From the viewpoint of thickness uniformity, the film thickness is preferably in the above range.

ここで用いられる基材としては、ガラス、ポリエチレンテレフタレート、ポリエチレンナフタレート、ポリカーボネートなどからなるフィルムが挙げられる。 Examples of the base material used here include films made of glass, polyethylene terephthalate, polyethylene naphthalate, polycarbonate and the like.

[工程2]

部分的に活性エネルギー線4を照射する方法としては、活性エネルギー線4を透過しないパターンを具備するマスクを用い、マスク越しに全面に照射(露光)する方法や、マスクを用いずに活性エネルギー線4により硬化塗膜上にパターンを直に描画する方法なども挙げられる。
露光に用いられる活性エネルギー線としては、紫外線、電子線、X線、放射線、高周波などを挙げることができ、紫外線が経済的に最も好ましい。紫外線の光源としては、紫外線レーザ、水銀ランプ、キセノンレーザ、メタルハライドランプなどが挙げられる。
[Step 2]
In step 2, as shown in FIG. 2, the cured coating film of the latent image forming composition of the present invention formed on the substrate is partially irradiated with the active energy rays 4 to change the properties of the irradiated portion 3. This is a step of changing the ink repellency to form a latent image 2 corresponding to a non-irradiated portion.
As a method of partially irradiating the active energy ray 4, a mask having a pattern that does not transmit the active energy ray 4 is used, and the entire surface is irradiated (exposed) through the mask, or the active energy ray is not used. A method of directly drawing a pattern on the cured coating film according to No. 4 can also be mentioned.
Examples of the active energy beam used for exposure include ultraviolet rays, electron beams, X-rays, radiation, and high frequencies, and ultraviolet rays are most economically preferable. Examples of the ultraviolet light source include an ultraviolet laser, a mercury lamp, a xenon laser, and a metal halide lamp.

工程(3)は、図3に示すように、前記表面が撥インキ化された照射部以外の領域に後述するインキを付着させ、潜像を現像し、パターンを可視化したり、パターンに応じた機能を発現したりする工程である。
[Step 3]
In the step (3), as shown in FIG. 3, the ink described later is adhered to a region other than the irradiation portion whose surface is ink-repellent, a latent image is developed, the pattern is visualized, and the pattern is adapted. It is a process of expressing a function.

<インキ>
潜像を可視化する際に用いられるインキについて説明する。
インキは特に限定されるものではないが、例えば、導電性インキ、磁性インキ等のように主に機能発現を目的とするインキの他、顔料や染料を含む着色性インキのように主に可視化を目的とするインキが挙げられる。

これらの中でも、導電性インキが好ましく、特に導電性と塗工性の観点から金属粒子を分散したインキが好ましい。
前記導電性インキとしては、一般的な導電性材料を用いることができるが、基材に合成樹脂性のフィルム(プラスチックフィルム)を用いる場合には、低温プロセスを適用するので比較的低温(例えば、150度以下)で硬化するインキがよい。
<Ink>

An ink that cures at 150 degrees or less is preferable.

インキの付着方法(印刷方法)としては特に限定されず、ディップ法、スプレー法、ロールコート法、スピンコート法、スリットダイ塗布法、バー塗布法、フレキソ印刷、オフセット印刷、インクジェット印刷、ディスペンス法等の適宜の方法を採用することができる。 The ink adhesion method (printing method) is not particularly limited, and the dip method, spray method, roll coating method, spin coating method, slit die coating method, bar coating method, flexographic printing, offset printing, inkjet printing, dispensing method, etc. Appropriate method can be adopted.
