Definitions
- the present invention relates to an ink-jet ink receiving layer suitable for obtaining a pattern-like printed pattern from ink-jet ink ejected by an ink-jet apparatus, and more specifically, an ultraviolet curable resin composition coated on a non-absorbent substrate is selected.
- the present invention relates to an ink-jet ink receiving layer in which a good pattern-like printed pattern can be obtained by irradiating a target ultraviolet ray and discharging the ink-jet ink to an unirradiated ultraviolet ray portion.
- Ink jet methods represented by ink jet printers are not only used as conventional output means for paper media, but in recent years, for example, forming each pixel in a color filter and producing a printed wiring board by discharging conductive ink, etc. Then, the use in the field of electronic devices such as semiconductor devices is also increasing. This is due to the fact that the inkjet method is superior in controlling the amount of droplets discharged from the nozzle and the discharge position, and its use is expected to expand in various fields in the future. .
- a receiving layer may be used to encourage the ink ejected from an inkjet printer or the like to be adsorbed and fixed to the support medium (base material), and on the printing surface of commercially available paper for inkjet printers or overhead projector sheets for inkjet printers.
- this ink jet receiving layer (ink jet ink receiving layer) is formed, whereby a clear printed matter with less blur can be produced (for example, see Patent Document 1).
- the inkjet method is not limited to consumer inkjet printers, but is also being applied to industrial applications.
- a technique for manufacturing a color filter for a display device as disclosed in Patent Document 2 a matrix-shaped light-shielding layer is formed on an ink-jet receiving layer, and a patterned colored layer is formed between the matrix-shaped light-shielding layers by an ink-jet method.
- the ink jet receiving layer plays an important role in forming the patterned colored layer, such as fixing the colored layer forming ink and preventing the ink from diffusing outside the target lattice.
- Patent Document 3 introduces a technique for preventing color mixture between pixels. That is, an ink jet receiving layer is made of an ultraviolet curable resin, and only the ink jet receiving layer existing on the matrix-shaped light shielding layer is exposed and cured using a pattern mask to increase the thickness of the light shielding layer in a pseudo manner. It prevents diffusion of the forming ink. However, even if an attempt is made to fill more colored layer forming ink to improve the color characteristics, it is not possible to fill ink that exceeds the capacity of the ink jet receiving layer.
- an ink jet receiving layer is particularly used to form a fine pattern.
- Patent document 4 etc. are mentioned as an example, and the inkjet receiving layer in this case controls the wettability of the substrate surface. That is, the substrate surface provided with the receiving layer is irradiated with deep ultraviolet rays to control the wettability of the substrate surface, and the conductive ink is ejected to the wettable portion by the ink jet device to form the wiring.
- this technique has to irradiate a considerable amount of deep ultraviolet rays (wavelength of about 300 nm or less), which is difficult for mass production. Also in this case, it is difficult to increase the discharge amount of the conductive ink for the purpose of achieving good conductivity.
- the inkjet receptive layer formed on the dedicated paper / sheet for the inkjet printer contains polyvinyl alcohol, polyester, polyurethane, an acrylic resin emulsion or the like as a binder component, and is composed of inorganic particles such as silica.
- the majority for example, see Patent Document 1 and Patent Document 2).
- Patent Document 1 and Patent Document 2 when these receiving layers require water resistance, it is difficult to apply them to electronic components from the viewpoint of reliability.
- an ink jet receiving layer formed of a photo-curing resin as described in Patent Document 5 can be cited.
- application of the present technology to electronic parts is difficult because electronic parts are required to have higher heat resistance than the printing / printing field.
- an object of the present invention is to provide an ink-jet ink receiving layer suitable for producing electronic devices such as color filters and wiring boards.
- the present inventors selectively irradiate a predetermined ultraviolet curable resin composition coated on a non-absorbent substrate with ultraviolet rays, and perform inkjet on unirradiated portions.
- the present inventors have found that a good pattern-like printed pattern can be obtained even when the amount of ink is increased by discharging ink, and the present invention has been completed. That is, the gist of the present invention is as follows.

本発明における紫外線硬化樹脂組成物には、表面調整剤としてフッ素原子を有する化合物を配合すると良い。これに用いる化合物として、例えば、DIC社製のメガファックシリーズやディフェンサシリーズ、AGCセイミケミカル社製のサーフロンシリーズ、ネオス社製のフタージェントシリーズ、ダイキン社製のオプツールシリーズなどが挙げられる。これらの化合物は、二種類以上混合して使用すると異物などが発生する可能性が高く、単独での使用が望ましい。本化合物群を添加した紫外線硬化樹脂組成物より形成されたインクジェット受容層は、フッ素原子の働きにより表面が撥液化される。そのため、インクジェット印刷すると未添加の場合と比較して紫外線照射部分と未照射部分の境界線がよりクリア(鮮明)となる。
本発明の受容層を形成するための紫外線硬化樹脂組成物において、必要に応じて上記(A)~(E)以外の成分を添加してもかまわない。その他の成分として、染料や顔料などの色材、ポリエステル樹脂やポリウレタン樹脂、アクリル樹脂、エポキシ樹脂などの光反応性のないバインダー樹脂、アルミナやマイカ、シリカのような充填剤、レベリング剤や消泡剤、可塑剤、カップリング剤、硬化剤、紫外線吸収剤、光安定剤、酸化防止剤、蛍光増白剤などの添加剤を適宜含有しても良い。
本発明における非吸収性基材とは、ポリエチレンやポリプロピレン、ポリエチレンテレフタレート、ポリカーボネート、ポリイミド、フッ素樹脂、シリコーン樹脂などの有機基材や、ガラスやシリコンウエハー、鉄板、銅箔などの無機基材、ITO(インジウムスズ酸化物)などの薄膜がポリエチレンテレフタレートフィルム上などに形成された複合基材などが挙げられる。本基材は作成する電子デバイスなどの特性や紫外線硬化樹脂組成物の塗工方法によって選ばれるものであって、紙や布の様に紫外線硬化樹脂組成物の溶剤を吸収するものではない。
紫外線硬化樹脂組成物の塗工方法には特に制限はなく、公知の方法、例えば、スピンコート法、ディップコート法、バーコート法、ブレードコート法、エアナイフコート法、ロールコート法、スクリーン印刷法などの何れの方法も採用することができ、塗工する基材、塗工厚に応じて適宜選択される。塗工厚は、乾燥膜厚に換算して1.0~100μmが望ましい。さらに望ましくは5.0~50μmである。塗工厚が乾燥膜厚に換算して1μm未満の場合、作成したインクジェット受容層が所望の性能を発揮しないおそれがある。また、インクジェット受容層の性能上、乾燥膜厚に換算して100μmを超える厚みまでは必要とされない。
紫外線硬化樹脂組成物の乾燥方法には、オーブン、ホットプレート等による加熱、真空乾燥又はこれらの組み合わせることによって行われる。本発明における乾燥方法は、紫外線硬化樹脂組成物中の(A)溶剤の種類や基材の種類によって適宜選択される。ただし、乾燥温度としては45~120℃が望ましい。45℃未満の場合、乾燥膜中に溶剤が残留してしまう可能性があり、120℃超の場合、組成物中の活性基が失活してしまう可能性がある。乾燥時間としては、例えば1~10分間程度行わればよい。
本発明において用いる紫外線とは、主に250nmから400nmの波長を含む電磁波である。本発明で使用する紫外線光源としては、高圧水銀灯やメタルハライドランプ、UV-LEDランプなどが挙げられるが、特に制限はない。次に、これら光源を用いて紫外線を紫外線硬化樹脂組成物の乾燥塗膜に選択的に照射する。ここで使用する選択的に紫外線照射を行うとは、例えば、配線形成を目的とした場合、導電性インクにより導電膜を形成しない部分、すなわち、回路配線パターンの非導電部分に対して紫外線照射を行うことであり、例えばカラーフィルターの作成を目的とした場合、着色用インクにより色画素を形成しない部分、すなわち、マトリックスパターンの隔壁部分(ブラックマトリックスが形成される部分)に紫外線照射を行うことである。選択的紫外線照射の方法としては、レンズなどを用いて紫外線を集光させこれにより直接的に行う方法やフォトマスクなどを用いる方法などが挙げられる。露光量は10~5000mJ/cm2が望ましい。10mJ/cm2未満の場合、紫外線照射の影響が小さくインク受容層の溶剤吸収量にほとんど差が無く、反対に5000mJ/cm2超の場合、露光時間が長くなり生産性が悪くなる。
微細化顔料(ピグメントブルー15:6)を顔料親和性官能基を有する高分子量体(高分子分散剤)の共存下、ジエチレングリコールモノエチルエーテルアセテートを溶剤としてビーズミル中で分散を行い、青色分散液を調製した。この分散液をもとに表1に示す組成となるように各成分を混合し、混合溶液を1μmマイクロフィルターによって加圧ろ過を行い、インクジェットインクを調製した。
