Definitions
- the present invention relates to an inkjet ink composition for an etching resist, and more particularly to an active energy ray-curable inkjet ink composition for an etching resist.
- an etched metal plate having an uneven shape formed by etching on the surface of a metal plate is used for elevator door materials and the like that require a high-class feeling due to its design.
- an etching metal plate is formed by 1) applying a photosensitive resin to one or both sides of a metal plate to form a resin film, and 2) closely adhering a pattern-formed negative film (also referred to as “resist pattern”) to the metal plate. Exposure to cure the exposed portion of the photosensitive resin film, 3) remove the non-photosensitive portion of the photosensitive resin film by development, and 4) etch the metal with a corrosive solution such as iron perchloride. ) Manufactured by alkali treatment of cured resin film.
- the photosensitive resin also referred to as “etching resist resin”
- the metal plate is pretreated.
- the metal plate is washed and dried after degreasing treatment such as alkali degreasing, solvent degreasing or electrolytic degreasing.
- the metal plate may be further pickled after the degreasing treatment, and then washed and dried.

- the metal plate may be further pickled after the degreasing treatment, and then washed and dried.
- a metal since a metal generally has a thick oxide film on its surface, even if sufficient degreasing treatment is performed, adhesion with an etching resist resin is often insufficient.
- the etching solution tends to enter the interface between the metal surface and the etching resist resin, and the etching in the side surface direction is accelerated, and the side etching tends to increase. Further, if the adhesion is not sufficient, partial peeling of the etching resist film easily occurs, and unexpected corrosion occurs. Therefore, if the adhesiveness is not sufficient, it becomes difficult to precisely process the etched metal plate into a target shape. From the above, the etching resist resin is required to have sufficient adhesion to the metal plate.

Therefore, this method does not require a separate resist pattern and is excellent in workability, and can easily cope with design changes. Therefore, this method is particularly suitable for the production of a small variety of printed wiring boards. Furthermore, since this method can directly draw a resist pattern, a development step at the time of producing the resist pattern is unnecessary, and it is said that the method is excellent in environmental compatibility.

本発明の第1のエッチングレジスト用インクジェットインキ組成物(以下、単に「第1のインキ組成物」ともいう)は、活性エネルギー線により重合可能な重合性モノマーを含む。この重合性モノマーは、全モノマー中に、(1-1)分子内にリン酸エステル基とエチレン性二重結合基を有する重合性リン酸エステル化合物を0.5~13質量%と、(2)分子内に2個以上のエチレン性二重結合基を有し、リン酸エステル基を有さない多官能性モノマーであって、前記エチレン性二重結合基量が4×10-3~8×10-3mol/gである多官能性モノマーを10~75質量%と、(2)分子内に1個のエチレン性二重結合基を有し、リン酸エステル基とカルボキシル基を有さない単官能性モノマーを10~75質量%を含み、25℃における粘度は、3~50mPa・sであることを特徴とする。本発明において記号「~」は、その両端の数値を含む。
重合性リン酸エステル化合物とは、分子内にリン酸エステル基とエチレン性二重結合基を有する化合物である。重合性リン酸エステル化合物は、カルボキシル基を含む化合物に比べ、金属密着性向上に大きな効果がある。そのため、少量でその効果が得られることから、これを含むインキ組成物は、粘度を低くすることができる。よって、重合性リン酸エステル化合物を含む本発明のインキ組成物は、粘度の上昇を伴わずして、耐エッチング液性やアルカリ剥離性が向上する。
分子内に(メタ)アクリロイル基と水酸基を有する化合物の例には以下のものが含まれる。
2-ヒドロキシメチル(メタ)アクリレート、2-ヒドロキシプロピル(メタ)アクリレート、2-ヒドロキシブチル(メタ)アクリレート、4-ヒドロキシブチル(メタ)アクリレート、1,4-シクロヘキサンジメタノールモノ(メタ)アクリレート等のヒドロキシアルキル(メタ)アクリレート。
第1のインキ組成物は、分子内に2個以上のエチレン性二重結合基を有し、リン酸エステル基を有さない多官能性モノマーであって、エチレン性二重結合基量が4×10-3~8×10-3mol/gである多官能性モノマー(以下、「特定多官能性モノマー」ともいう)を、全モノマー中に10~75質量%含む。特定多官能性モノマーの例には、分子内にエチレン性二重結合基を2~6個含有する化合物が含まれる。中でも、特定多官能性モノマーとしては、分子内に2個以上の(メタ)アクリロイル基を含む化合物が好ましい。入手が容易であり、かつ活性エネルギー線により重合しやすいからである。
二種類以上の多官能性モノマーを用いる場合、本発明の特定多官能性モノマーのエチレン性二重結合基量は、次のように求められる。例えば、次のi)~iii)の多官能性モノマーを用いる場合、エチレン性二重結合基量は、式(1)で求められる。
モノマーx:エチレン性二重結合基数Nx(個)、分子量Mx(g/mol)、配合比率x(質量%)
モノマーy:エチレン性二重結合基数Ny(個)、分子量My(g/mol)、配合比率y(質量%)

これに対して、Xが炭素数4以上のアルキレン基であると、カルボニル基とカルボキシル基の距離が遠くなりすぎるため、分子内会合が起こりにくくなる。また、Xが1,2-フェニレン基のような芳香族炭化水素基であると、カルボニル基が結合する芳香環上の2つの炭素間の結合が回転できないため、分子内会合が起こりにくくなる。分子内会合が起こりにくい化合物は、前述のとおり、式(2)で表されるように他の分子と会合して二量化しやすくなる。

第2のインキ組成物は、表面張力が20~40mN/mであることが好ましい。第1のインキ組成物と同様の効果が得られるからである。
本発明のインキ組成物は、混合機、分散機、撹拌機を用いて各成分を分散または溶解して製造される。この混合機、分散機、撹拌機の例には、プロペラ型撹拌機、ディゾルバー、ホモミキサー、ボールミル、サンドミル、超音波分散機、ニーダー、ラインミキサー、プロペラ型撹拌機、ピストン型高圧乳化機、ホモミキサー、超音波式乳化分散機、加圧ノズル式乳化機、高速回転高せん断型撹拌分散機、コロイドミル、およびメディア型分散機が含まれる。メディア型分散機とは、ガラスビーズおよびスチールボール等の媒体を使用して粉砕・分散を行う装置である。その例には、サンドグラインダー、アジテーターミル、ボールミルおよびアトライター等が含まれる。これらの装置は2種以上を組み合わせて用いてもよい。また、混合機、分散機、撹拌機は組み合わせて使用することもできる。
インキ組成物は、孔径3μm以下、さらには1μm以下のフィルターにて濾過されることが好ましい。
本発明のインキ組成物を用いることにより、エッチング金属板が製造できる。エッチング金属板は、本発明の効果を損なわない限り任意に製造してよいが、以下好ましい方法を説明する。
エッチング金属板は、(a)金属板の上に本発明のインキ組成物を吐出する工程と、(b)活性エネルギー線を照射して前記組成物を硬化させる工程と、(c)前工程で得た金属板の表面をエッチングする工程と、(d)エッチングされた金属板をアルカリ液で処理して、前記硬化された組成物を除去する工程、を含む方法で製造されることが好ましい。
本発明においては、活性エネルギー線源として、320~390nmのメタルハライドランプを用いることが好ましい。また、GaN系の紫外LEDや紫外LDは、水銀を使用しないため環境保護の観点から好ましい。紫外LDは小型、高寿命、高効率、かつ低コストであり、光硬化型インクジェット用光源として期待されている。
硬化膜の総膜厚は、2~20μmであることが好ましい。前記膜厚が2μm未満では十分な耐エッチング液性を保持することが困難となる場合がある。逆に前記膜厚が20μmを超えると十分な解像度を得ることが難しくなることがある。本発明においては、活性エネルギー線照射後、必要に応じて硬化膜に熱処理を行なってもよい。熱処理により硬化膜の内部応力緩和等の効果が発現し、金属板と硬化膜の密着性が向上する場合がある。
(d)工程では、エッチングされた金属板をアルカリ液で処理して、前記硬化された組成物を除去する。この工程も金属板を水酸化ナトリウム溶液に浸漬する等の公知の方法で行えばよい。
