Description
本発明は、ラジカル重合性インク組成物に関する。 The present invention relates to a radical polymerizable ink composition.
オフセットインキ、グラビアインキ、フレキソインキ、シルクスクリーンインキ等の印刷インキ分野やインキジェット記録用インキ分野においては、近年、希釈・溶解用の有機溶剤等の非重合性溶剤を実質的に含有せず、VOC(揮発性有機物質)を出さないという環境調和性の点でもメリットがある活性エネルギー線硬化性インクが注目されている。 In the printing ink field such as offset ink, gravure ink, flexo ink, silk screen ink and ink jet recording ink field, in recent years, it does not substantially contain non-polymerizable solvents such as organic solvents for dilution and dissolution, Active energy ray-curable inks that are advantageous in terms of environmental harmony that do not emit VOC (volatile organic substances) are drawing attention.
活性エネルギー線硬化性インクは、着色剤である顔料と活性エネルギー線重合性化合物、必要に応じて活性エネルギー線感受性重合開始剤を加え、印刷に適する粘度に調整される。この活性エネルギー線硬化性インクの硬化性は、光重合開始剤の感度に大きく依存する。さらに、重合開始剤もしくは重合開始剤由来の成分は、硬化後の臭気の原因となってしまうので過剰に用いることは望ましくない。従って、より少ない重合開始剤の添加で充分な硬化特性を達成できる重合開始剤が求められている。 The active energy ray curable ink is adjusted to a viscosity suitable for printing by adding a pigment as a colorant, an active energy ray polymerizable compound, and an active energy ray sensitive polymerization initiator as required. The curability of this active energy ray-curable ink greatly depends on the sensitivity of the photopolymerization initiator. Furthermore, since a polymerization initiator or a component derived from a polymerization initiator causes odor after curing, it is not desirable to use it excessively. Accordingly, there is a need for a polymerization initiator that can achieve sufficient curing characteristics with the addition of a smaller amount of polymerization initiator.
下記特許文献1には、活性エネルギー線硬化型インキに光重合開始剤としてα−アミノアルキルフェノン化合物を用いることが提案されている。また下記特許文献2には、インク組成物に光重合開始剤としてベンゾフェノンを用いることが提案されている。
しかし、下記特許文献に記載の光重合開始剤は低揮発性、低臭気性が十分でなく、硬化後の臭気の原因となっていた。
Patent Document 1 below proposes that an α-aminoalkylphenone compound is used as a photopolymerization initiator in an active energy ray-curable ink. Patent Document 2 below proposes using benzophenone as a photopolymerization initiator in the ink composition.
However, the photopolymerization initiators described in the following patent documents are insufficient in low volatility and low odor, and cause odor after curing.
解決しようとする問題点は、満足できる低臭気性を有する重合開始剤を用いたラジカル重合性インクがこれまでなかったということである。 The problem to be solved is that there has been no radical polymerizable ink using a polymerization initiator having a satisfactory low odor.
従って、本発明の目的は、安定性に優れ、低臭気性であり、365nm等の近紫外光を効率よく吸収し活性化される高感度の重合開始剤として有用な化合物を重合開始剤として用いたラジカル重合性インク組成物を提供することにある。 Accordingly, the object of the present invention is to use a compound useful as a polymerization initiator that is excellent in stability, has low odor, and is useful as a highly sensitive polymerization initiator that efficiently absorbs and activates near ultraviolet light such as 365 nm. Another object of the present invention is to provide a radically polymerizable ink composition.

上記硬化性の評価と同様にして作製した試料を、JIS D 0202の試験方法に従い、塗膜に基盤目状にクロスカットを入れ、次いでセロハンテープによってピーリングテストを行い、基盤目の剥離の状態を目視により評価した。全く剥離が認められなかったものをA、剥離が認められたものをBとした。
<硬化塗膜の臭気評価>
上記硬化性の評価と同様にして作製した試料を細断し、ガラス瓶に入れ、密栓をし、60℃のオーブンで1時間加熱した後、オーブンから取り出し放冷した。取り出しから1時間後に蓋を開けた直後に、5人に臭気性を相対的に判断してもらい、A(良好)〜C(不良)の3段階で評価した。尚、良好とは臭気が弱く、不良とは臭気が強い状態を言う。
<Curing property>
The radical polymerizable ink compositions obtained in Examples 1 to 7 and Comparative Examples 1 to 3 were applied to an easily adhered PET film having a thickness of about 6 μm using a bar coater # 20. A sample was prepared by irradiating the film with light of an 80 W / cm high-pressure mercury lamp using a light irradiation device with a belt conveyor. The presence or absence of tack was confirmed while touching the surface of the coating film with a finger. The distance from the ramp to the belt conveyor was 10 cm, and the line speed of the belt conveyor was 8 m / min.
○: There is no tack.
×: There is a tack.
<Adhesion>
In accordance with the test method of JIS D 0202, a sample prepared in the same manner as in the evaluation of the curability is subjected to a cross cut in a substrate pattern, and then a peeling test is performed with a cellophane tape to determine the state of peeling of the substrate eye. Visual evaluation was made. A case where no peeling was observed was designated as A, and a case where peeling was observed was designated as B.
<Odor evaluation of cured coating film>
A sample prepared in the same manner as in the evaluation of the curability was chopped, put into a glass bottle, sealed, heated in an oven at 60 ° C. for 1 hour, then taken out of the oven and allowed to cool. Immediately after opening the lid 1 hour after removal, 5 people were asked to make a relative judgment on odor, and the evaluation was made in three stages: A (good) to C (poor). “Good” means a weak odor, and “bad” means a strong odor.
実施例1〜7のラジカル重合性インク組成物No.1〜No.7から得られた塗膜は、硬化性、密着性に優れるものであり、低臭気であった。
Radical polymerizable ink compositions Nos. 1 to 7 in Examples 1 to 7 1-No. The coating film obtained from No. 7 was excellent in curability and adhesion, and had a low odor.
Claims (7)
A printed matter obtained by printing using the polymerizable ink according to claim 2 and curing the printed ink using an active energy ray.
