Abstract
Description
本発明は、活性エネルギー線条件下で良好な硬化性を有し、食品包装用向けパッケージ用途のための低毒性・低マイグレーション等安全性を保持する活性エネルギー線硬化型組成物、並びにその組成物を用いたインキとその印刷物や紙パッケージ、飲料容器に関する。 The present invention relates to an active energy ray-curable composition that has good curability under active energy ray conditions and retains safety such as low toxicity and low migration for package use for food packaging, and the composition thereof The present invention relates to an ink using the ink, its printed matter, a paper package and a beverage container.
紫外線照射条件下や電子線照射条件下で硬化する印刷インキは、その瞬間乾燥の特性の利便性から、紙器等の食品包装向けパッケージ印刷を中心に広く使用されている。
近年、食品包装において、インキ中の化学物質が内容食品へ移行（マイグレーション）する問題が懸念されており、例えば電子線（ＥＢ）硬化型インキの場合はインキ成分中の未反応モノマーが、紫外線（ＵＶ）硬化型インキの場合はインキ成分中の未反応光重合開始剤が、印刷面から裏移り（ブロッキング）し内容食品へ溶出することによるマイグレーションが問題となっている。
Printing inks that cure under ultraviolet irradiation conditions or electron beam irradiation conditions are widely used mainly for package printing for food packaging such as paper containers because of the convenience of instantaneous drying characteristics.
In recent years, in food packaging, there is a concern that the chemical substances in the ink migrate to the content food. For example, in the case of electron beam (EB) curable ink, unreacted monomer in the ink component is ultraviolet ( In the case of UV) curable ink, there is a problem of migration due to unreacted photopolymerization initiators in the ink components being offset (blocked) from the printed surface and eluted into the food.
例えば、流動パラフィンを用いた耐ブロッキング性に優れるオフセット印刷用インキ組成物が提案されているが、活性エネルギー線硬化型インキではなく一般の酸化重合型枚葉オフセットインキであり、食品包材向けでもない為、低マイグレーションを考慮したものとは言えない（例えば、特許文献１参照）。
また、常温で液体である特定のパラフィン又はポリオレフィンを添加した不揮発分５０％の活性エネルギー線硬化性組成物が提案されているが、スマートフォン、携帯端末、パソコン等のタッチスクリーンパネル向けに、硬化皮膜の透明性、指滑り性、耐傷付き性の改善を目的としたコーティングニスであり、低マイグレーションを考慮したものとは言えない（例えば、特許文献２参照）。一方でマイグレーションリスクを低減すべく、従来の高分子量の重合開始剤や、硬化反応性に優れるモノマー・オリゴマーを用い、低マイグレーションインキとして設計する手法が一般的とされているが、食品の安全性への要求が強まるに従い、更なるマイグレーションの抑制・低減を可能とするインキ製品が要望されている。
For example, although an ink composition for offset printing that uses liquid paraffin and has excellent blocking resistance has been proposed, it is a general oxidation polymerization type sheet-fed offset ink, not an active energy ray curable ink, and is also suitable for food packaging materials. Therefore, it cannot be said that low migration is taken into consideration (for example, see Patent Document 1).
In addition, an active energy ray-curable composition with a non-volatile content of 50%, which contains a specific paraffin or polyolefin that is liquid at room temperature, has been proposed, but it is a cured film for touch screen panels such as smartphones, portable terminals, and personal computers. The coating varnish is intended to improve the transparency, finger slipperiness, and scratch resistance, and it cannot be said that low migration is taken into consideration (for example, see Patent Document 2). On the other hand, in order to reduce migration risk, conventional high molecular weight polymerization initiators and monomers / oligomers with excellent curing reactivity are commonly used to design as low migration inks, but food safety As the demand for the ink becomes stronger, there is a demand for an ink product that can further suppress or reduce migration.
本発明の課題は、良好な硬化性、食品包装用途のための低毒性、低マイグレーション性を兼ね備えた活性エネルギー線硬化型組成物を提供することにある。 An object of the present invention is to provide an active energy ray-curable composition having good curability, low toxicity for food packaging use, and low migration.
本発明者らは、常温において液体でかつ特定の粘度を持つ炭化水素ワックスを適量と、モノマー、及び光重合開始剤を適宜組合せ採用することで、上記課題を達成できることを見出し、本発明に至った。 The present inventors have found that the above-mentioned problems can be achieved by appropriately adopting a suitable amount of a hydrocarbon wax that is liquid at normal temperature and having a specific viscosity, a monomer, and a photopolymerization initiator, leading to the present invention. It was.
即ち、炭化水素ワックス、モノマー、及び光重合開始剤を含有する活性エネルギー線硬化型組成物であって、前記炭化水素ワックスが２５℃において液体であり、粘度が３００〜４０００ミリパスカル秒（ｍＰａ・ｓ）の範囲であり、且つ炭化水素ワックスの含有量が活性エネルギー線硬化型組成物中の不揮発成分１００重量％に対して０．１〜５重量％であることを特徴とする活性エネルギー線硬化型組成物を提供するものである。 That is, an active energy ray-curable composition containing a hydrocarbon wax, a monomer, and a photopolymerization initiator, wherein the hydrocarbon wax is liquid at 25 ° C. and has a viscosity of 300 to 4000 millipascal seconds (mPa · s), and the content of the hydrocarbon wax is 0.1 to 5% by weight with respect to 100% by weight of the non-volatile component in the active energy ray curable composition.

本発明は、更に光重合開始剤の数平均分子量が３２０〜１５００の範囲であり、且つ光重合開始剤の含有量が活性エネルギー線硬化型組成物中の不揮発成分１００重量％に対して４〜３０重量％である請求項１又は２に記載の活性エネルギー線硬化型組成物に関する。 In the present invention, the number average molecular weight of the photopolymerization initiator is in the range of 320 to 1500, and the content of the photopolymerization initiator is 4 to 100% by weight with respect to 100% by weight of the nonvolatile component in the active energy ray-curable composition.

The present invention relates to a curable composition.
本発明は、更に前記活性エネルギー線硬化型組成物を用いた活性エネルギー線硬化型オフセット印刷インキに関する。 The present invention further relates to an active energy ray-curable offset printing ink using the active energy ray-curable composition.
本発明は、更に前記活性エネルギー線硬化型オフセット印刷インキを用いてポリエチレンラミネート紙に印刷し成形された飲料容器をも提供する。 The present invention also provides a beverage container formed by printing on polyethylene laminated paper using the active energy ray-curable offset printing ink.
発明の硬化性と低マイグレーション性能を両立する活性エネルギー線硬化型組成物を用いることで、より化学物質のマイグレーション量が少なく、安全性に優れる食品包装を提供することができる。 By using the active energy ray-curable composition that achieves both curability and low migration performance, it is possible to provide a food packaging with less chemical migration and excellent safety.
本発明は、炭化水素ワックス、モノマー、及び光重合開始剤を含有する活性エネルギー線硬化型組成物であって、前記炭化水素ワックスが２５℃において液体であり、粘度が３００〜４０００ミリパスカル秒（ｍＰａ・ｓ）の範囲であり、且つ炭化水素ワックスの含有量が活性エネルギー線硬化型組成物中の不揮発成分１００重量％に対して０．１〜５重量％であることを特徴とする活性エネルギー線硬化型組成物を提供することで目的とする本発明の効果を奏するものである。 The present invention relates to an active energy ray-curable composition comprising a hydrocarbon wax, a monomer, and a photopolymerization initiator, wherein the hydrocarbon wax is liquid at 25 ° C. and has a viscosity of 300 to 4000 millipascal seconds ( mPa · s) and the content of the hydrocarbon wax is 0.1 to 5% by weight with respect to 100% by weight of the non-volatile component in the active energy ray-curable composition. By providing a wire curable composition, the intended effect of the present invention is achieved.
本発明の活性エネルギー線硬化型組成物で使用する炭化水素ワックスとしては、２５℃においてその性情は液体であり、その粘度は３００〜４０００ミリパスカル秒（ｍＰａ・ｓ）の範囲であり、その含有量は活性エネルギー線硬化型組成物中の不揮発成分１００重量％に対して０．１〜５重量％である。
本発明の活性エネルギー線硬化型組成物で使用する前記液状の炭化水素ワックスは直鎖状、分岐状、環状等の分子構造を有し、また飽和炭化水素、不飽和炭化水素等の混合物から構成されるが特に限定されるものではなく、前述の性状を満たすものを適宜用いることができるが、主成分の沸点が４００℃以上であることが、組成物中のＶＯＣ（揮発性有機化合物）量を抑制する点において好ましい。
The hydrocarbon wax used in the active energy ray-curable composition of the present invention has a liquid nature at 25 ° C., and its viscosity is in the range of 300 to 4000 millipascal seconds (mPa · s). The amount is 0.1 to 5% by weight based on 100% by weight of the nonvolatile component in the active energy ray-curable composition.
The liquid hydrocarbon wax used in the active energy ray curable composition of the present invention has a linear, branched, cyclic, etc. molecular structure, and is composed of a mixture of saturated hydrocarbon, unsaturated hydrocarbon, etc. However, it is not particularly limited, and those satisfying the above-mentioned properties can be used as appropriate. However, the boiling point of the main component is 400 ° C. or more, and the amount of VOC (volatile organic compound) in the composition It is preferable at the point which suppresses.
前記液状の炭化水素ワックスは、硬化時にインキ塗膜上面に薄膜を形成し、未反応モノマーや未反応光重合開始剤の成分移行を抑制するものと推察される。一方で、固体ワックスを例に挙げれば、固体ワックスは「点」として塗膜中に点在するため、成分移行を抑制する効果が得られない。
前記液状の炭化水素ワックスについて、粘度が３００（ｍＰａ・ｓ）を下回ると、硬化性および低マイグレーション性能が低下する傾向にあり、粘度が４０００（ｍＰａ・ｓ）を超えると、活性エネルギー線硬化型組成物に含まれるモノマーや樹脂との相溶性が低下し、組成物の流動性が低下する傾向にある。また、液状の炭化水素ワックスの添加量について、まったく添加しないと耐スクラッチ性が保持できず、マイグレーションも抑制できない傾向にあり、活性エネルギー線硬化型組成物中の不揮発成分１００重量％に対して５重量％を超えると硬化塗膜が軟化し、低マイグレーション性能および硬化性が悪化する傾向にある。
It is surmised that the liquid hydrocarbon wax forms a thin film on the upper surface of the ink coating during curing, and suppresses component migration of unreacted monomers and unreacted photopolymerization initiators. On the other hand, if a solid wax is mentioned as an example, since the solid wax is scattered as "spots" in the coating film, the effect of suppressing component migration cannot be obtained.
When the viscosity of the liquid hydrocarbon wax is less than 300 (mPa · s), the curability and the low migration performance tend to be lowered, and when the viscosity exceeds 4000 (mPa · s), the active energy ray curable type is used. Compatibility with monomers and resins contained in the composition tends to decrease, and the fluidity of the composition tends to decrease. In addition, with respect to the amount of liquid hydrocarbon wax added, scratch resistance cannot be maintained unless migration is added at all, and migration tends not to be suppressed, and is 5% with respect to 100% by weight of the nonvolatile component in the active energy ray-curable composition. When it exceeds wt%, the cured coating film is softened and the low migration performance and curability tend to deteriorate.
また、前記炭化水素ワックスの数平均分子量は１２００〜２００００の範囲が好ましく、より好ましくは１５００〜１００００の範囲であり、更に好ましくは１８００〜５０００の範囲である。数平均分子量が１２００を下回ると、硬化性および低マイグレーション性能が低下する傾向にあり、数平均分子量が２００００を上回ると、活性エネルギー線硬化型組成物に含まれるモノマーや樹脂との相溶性が低下し、組成物の流動性が低下する傾向にある。 The number average molecular weight of the hydrocarbon wax is preferably in the range of 1200 to 20000, more preferably in the range of 1500 to 10000, and still more preferably in the range of 1800 to 5000. When the number average molecular weight is less than 1200, the curability and low migration performance tend to be lowered. When the number average molecular weight is more than 20000, the compatibility with the monomer or resin contained in the active energy ray-curable composition is lowered. However, the fluidity of the composition tends to decrease.

前記光重合開始剤のうち、数平均分子量が３２０〜１５００の範囲にある光重合開始剤を用いることが、より良好な低マイグレーション性と硬化性を得る点においてより好ましい。数平均分子量３２０〜１５００の範囲にある光重合開始剤の具体例として、α−アミノアルキルフェノン系光重合開始剤としては、２−ベンジル−２−ジメチルアミノ−１−（４−モルフォリノフェニル）−ブタノン−１（数平均分子量：３６６．５）、２−（ジメチルアミノ）−２−（４−メチル−ベンジル）−１−（４−モルフォリン−４−イル−フェニル）−ブタン−１−オン（数平均分子量：３８０．５）等を、アシルフォスフィンオキサイド系光重合開始剤としては、ビス（２、４、６−トリメチルベンゾイル）−フェニルフォスフィンオキサイド（数平均分子量４１８．５）、２，４，６−トリメチルベンゾイル−ジフェニルフォスフィンオキサイド（数平均分子量３４８．０）等を、α−ヒドロキシケトン系光重合開始剤としては、２−ヒドロキシ−１−{４−[４−（２-ヒドロキシ−２−メチル−プロピオニル）−ベンジル]−フェニル}−２−メチル−プロパン−１−オン（数平均分子量：３４０．４）、オリゴ（２−ヒドロキシ−２−メチル−１−[４−（１−メチルビニル）フェニル]プロパノン）（数平均分子量：４２４．５７）、２−ヒドロキシ−１−{４−〔４−(２−ヒドロキシ−２−メチルプロピオニル)フェノキシ〕フェニル}−２−メチルプロパノン（数平均分子量：３４２．３９）等を挙げることができ、これらはどれか１つ以上含まれればよく、複数組み合わせて用いてもよい。中でも、２−ベンジル−２−ジメチルアミノ−１−（４−モルフォリノフェニル）−ブタノン−１、２−ヒドロキシ−１−{４−[４−（２-ヒドロキシ−２−メチル−プロピオニル）−ベンジル]−フェニル}−２−メチル−プロパン−１−オンの組合せがより好ましい。 Among the photopolymerization initiators, it is more preferable to use a photopolymerization initiator having a number average molecular weight in the range of 320 to 1500 in terms of obtaining better low migration properties and curability. As a specific example of a photopolymerization initiator having a number average molecular weight in the range of 320 to 1,500, an α-aminoalkylphenone photopolymerization initiator includes 2-benzyl-2-dimethylamino-1- (4-morpholinophenyl). -Butanone-1 (number average molecular weight: 366.5), 2- (dimethylamino) -2- (4-methyl-benzyl) -1- (4-morpholin-4-yl-phenyl) -butane-1- ON (number average molecular weight: 380.5) and the like, as acylphosphine oxide photopolymerization initiator, bis (2,4,6-trimethylbenzoyl) -phenylphosphine oxide (number average molecular weight 418.5), 2,4,6-trimethylbenzoyl-diphenylphosphine oxide (number average molecular weight 348.0) or the like as an α-hydroxyketone photopolymerization initiator Is 2-hydroxy-1- {4- [4- (2-hydroxy-2-methyl-propionyl) -benzyl] -phenyl} -2-methyl-propan-1-one (number average molecular weight: 340.4) , Oligo (2-hydroxy-2-methyl-1- [4- (1-methylvinyl) phenyl] propanone) (number average molecular weight: 424.57), 2-hydroxy-1- {4- [4- (2 -Hydroxy-2-methylpropionyl) phenoxy] phenyl} -2-methylpropanone (number average molecular weight: 342.39) and the like, and any one or more of these may be included and used in combination.

前記数平均分子量が３２０〜１５００の範囲にある光重合開始剤の使用量は、本発明の活性エネルギー線硬化型組成物中の不揮発成分１００重量％に対して４〜３０重量％の範囲にあることが好ましい。４重量％未満の使用量では良好な硬化性を得ることが困難であり、３０重量％を超える添加量では、開始剤量が過剰となり、保存安定性の低下（開始剤成分の析出）や低マイグレーション性能の低下をもたらすことから好ましくない。 The usage-amount of the photoinitiator which has the said number average molecular weights in the range of 320-1500 exists in the range of 4-30 weight% with respect to 100 weight% of non-volatile components in the active energy ray hardening-type composition of this invention. It is preferable. When the amount used is less than 4% by weight, it is difficult to obtain good curability. When the amount added exceeds 30% by weight, the amount of initiator becomes excessive, resulting in a decrease in storage stability (deposition of initiator components) and a low amount. This is not preferable because it causes a decrease in migration performance.
前記α−ヒドロキシケトン系光重合開始剤の他、特許第２５１４８０４号に記載される、開始剤分子に重合性基を導入したフェニルケトン系組成物群も硬化性と低マイグレーション性を付与する目的で利用できる。例えば具体的には、この組成物群のうち４−（２−アクリロイルオキシエトキシ）フェニル−（２−ヒドロキシ−２−プロピル）ケトンが「ダロキュアＺＬＩ３３３１」の名称で過去にメルク社（現ＢＡＳＦ社）より販売されており、本発明において利用することができる。またα−ヒドロキシケトン系光重合開始剤を高分子量化し重合性基を導入した組成物（数平均分子量約１１００）が「イルガキュアＬＥＸ２０１」の名称でＢＡＳＦ社より販売されており、低マイグレーション性能に優れており同様に本発明において好適に利用することができる。 In addition to the α-hydroxyketone photopolymerization initiator, the phenylketone composition group described in Japanese Patent No. 2514804, in which a polymerizable group is introduced into the initiator molecule, also provides curability and low migration properties.

Further, as a means for improving curability, an aromatic tertiary amine compound having a number average molecular weight in the range of 320 to 1500 may be added as a sensitizer.

For example, catalogs, posters, flyers, CD jackets, direct mails, brochures, cosmetics and beverages, pharmaceuticals High quality paper, coated paper, art paper, imitation paper, thin paper, cardboard paper, various synthetic papers, polyester resin, acrylic resin, vinyl chloride resin, vinylidene chloride resin, used for printing packages such as toys and equipment Polyvinyl alcohol, polyethylene, polypropylene, polyacrylonitrile, ethylene vinyl acetate copolymer, ethylene vinyl alcohol copolymer, ethylene methacrylic acid copolymer, nylon, polylactic acid, polycarbonate film or sheet, cellophane, aluminum foil, etc. It can be mentioned various substrates that have been used as a printing substrate from come. Among them, a film laminate base material represented by polyethylene laminated paper (milk carton paper) is widely used in beverage containers, and is caused by the ink component being set off when the printed material is stacked or stored in a wound state. Although it is important to suppress migration to the contents, it is possible to impart excellent low migration performance by using the active energy ray-curable composition of the present invention.
また、本発明の活性エネルギー線硬化性組成物の利用方法としては、例えば、平版オフセット印刷、凸版印刷、グラビア印刷、グラビアオフセット印刷、フレキソ印刷、スクリーン印刷等の各種印刷インキおよびコーティングニス等が挙げられる。 Examples of the method for using the active energy ray-curable composition of the present invention include various printing inks such as lithographic offset printing, relief printing, gravure printing, gravure offset printing, flexographic printing, and screen printing, and coating varnishes.

When the coating thickness of the varnish is less than 1 micrometer, good gloss cannot be obtained, and when it exceeds 8 micrometers, unevenness (swimming) of the varnish surface is likely to occur, and ultraviolet energy given from the ultraviolet irradiation lamp is reduced. Since a large amount of varnish layer is consumed, it is not preferable to use UV curable offset ink as the base because the ink layer is liable to be hardened.
本発明の活性エネルギー線硬化型組成物を用いた紫外線硬化型オフセット印刷インキの製造は、従来の紫外線硬化型オフセットインキと同様に、前記炭化水素ワックス、モノマー、光重合開始剤、増感剤、予め合成した樹脂ワニス、重合禁止剤ベース、その他添加剤等を配合してミキサー等で撹拌混合し、三本ロールミル、ビーズミル等の分散機を用いて練肉することで製造される。 The production of the ultraviolet curable offset printing ink using the active energy ray curable composition of the present invention is the same as the conventional ultraviolet curable offset ink, the hydrocarbon wax, monomer, photopolymerization initiator, sensitizer, It is manufactured by blending a resin varnish synthesized in advance, a polymerization inhibitor base, other additives, etc., stirring and mixing with a mixer, etc., and kneading using a dispersing machine such as a three-roll mill or bead mill.

[Method for producing ink composition]
Various ultraviolet curable ink compositions were obtained by kneading the inks of Examples 1 to 7 in Table 1 and Comparative Examples 1 to 9 in Table 2 with a three-roll mill.
In addition, 33% by weight of urethane acrylate varnish 1, 14% by weight of carbon black (raben 1060Ultra) as a color material, 4% by weight of phthalocyanine blue and 2.5% by weight of dioxazine violet as complementary color components (total color material 20.5%) %), 1% by weight of talc (high filler # 5000PJ) as a viscosity modifier, and 1.5% by weight of the polymerization inhibitor base 1 were commonly added to all examples. Incidentally, phthalocyanine blue and dioxazine violet, which are complementary color components, are blended in a small amount for the purpose of counteracting the yellowness of carbon black itself and further enhancing the jetness of the ink. Such hue adjustment of the ink is called “complementary color”, and is a widely known technique.
〔印刷物の製造方法〕

[Method for producing printed matter]
The UV curable offset black ink obtained in this way is uniformly applied to the RI tester rubber roll and metal roll using a simple color developing machine (RI tester, manufactured by Toyoe Seiko Co., Ltd.) and black ink 0.10 ml. And uniformly applied to the surface of milk carton paper (polyethylene laminated paper, Tetra Rex, Tetra Pak) with a black ink density of 1.6 to 1.8 (measured with X-Rite SpectroEye densitometer) The color was developed as shown to produce printed matter. The RI tester is a test machine that develops ink on paper or film, and can adjust the amount of ink transferred and the printing pressure.
〔ＵＶランプ光源による乾燥方法〕
インキ塗布後の印刷物にＵＶ照射を行い、インキ皮膜を硬化乾燥させた。水冷メタルハライドランプ（出力１００Ｗ／ｃｍ１灯）およびベルトコンベアを搭載したＵＶ照射装置（アイグラフィックス社製、コールドミラー付属）を使用し、印刷物をコンベア上に載せ、ランプ直下（照射距離１１ｃｍ）を５０ｍ／分の速度で通過させた。各条件における紫外線照射量は紫外線積算光量系（ウシオ電機社製ＵＮＩＭＥＴＥＲ ＵＩＴ−１５０−Ａ／受光機ＵＶＤ−Ｃ３６５）を用いて測定した。
[Drying method using UV lamp light source]
The printed matter after the ink application was irradiated with UV, and the ink film was cured and dried. Using a UV irradiation device equipped with a water-cooled metal halide lamp (output: 100 W / cm1 lamp) and a belt conveyor (made by Eye Graphics Co., Ltd., with a cold mirror), the printed matter is placed on the conveyor, and directly under the lamp (irradiation distance: 11 cm) is 50 m. Per minute. The ultraviolet irradiation amount in each condition was measured using an ultraviolet integrated light quantity system (UNIMETER UIT-150-A / light receiving device UVD-C365 manufactured by USHIO INC.).
〔印刷物の評価方法１：硬化性〕
硬化性は、照射直後に爪スクラッチ法による耐スクラッチ性について、印刷物表面の傷付きの程度を目視評価した。
○：爪による傷付きは見られない。
△：爪による傷付きが僅かにみられる。
×：爪による傷付きが見られる。
[Evaluation Method of Printed Material 1: Curability]
As for the curability, the degree of scratching on the surface of the printed material was visually evaluated for scratch resistance by the nail scratch method immediately after irradiation.
○: No damage by nails is observed.
(Triangle | delta): The damage by a nail | claw is seen slightly.
X: Scratches by nails are observed.
〔印刷物の評価方法２：低マイグレーション性〕
前記印刷物を作製した直後に、紫外線硬化型オフセット墨インキを塗布した印刷面に対してポリ塩化ビニリデン製ラップフィルム（旭化成ケミカルズ社製）を貼り合わせ、２５℃、圧力１００ｋｇ／ｃｍ２の条件にて２４時間プレス処理を実施した。これにより墨インキ中の未反応の光重合開始剤およびモノマー等の低分子量成分がラップフィルム層へ移行（マイグレーション）する。プレス処理後、ラップフィルムを印刷物から剥がし、ラップフィルムの吸光度測定を実施することで、ラップフィルムにマイグレーションしたインキ成分を定量した。日本分光製紫外可視分光光度計ＪＡＳＣＯ Ｖ−５７０を用い、波長２００〜５００ｎｍの範囲において吸光度測定を実施した。
光重合開始剤はその分子構造により各々異なる紫外線吸収特性を有しており、例として２−ベンジル−２−ジメチルアミノ−１−（４−モルフォリノフェニル）−ブタノン−１は波長３２０ｎｍ近辺に紫外線吸収ピークを有しており、同様に２−ヒドロキシ−１−{４−[４−（２-ヒドロキシ−２−メチル−プロピオニル）−ベンジル]−フェニル}−２−メチル−プロパン−１−オンは波長２６０ｎｍ近辺に、２−メチル−１−[４−（メチルチオ）フェニル]−２−モルフォリノプロパン−１−オンは波長３００ｎｍ近辺に、１−ヒドロキシ−シクロヘキシル−フェニル−ケトンは波長２４０ｎｍ近辺に紫外線吸収ピークを有しているため、各波長における吸光度値を記録することで、各開始剤のマイグレーション量の大小を比較することが可能となる。
また波長２１０ｎｍ近辺では様々な光重合開始剤やアクリレートモノマー等の化合物の紫外線吸収ピークが重なり高い吸光度値を示すことから、波長２１０ｎｍの吸光度値を記録し比較することでも、低マイグレーション性能の優劣を判断することが可能となる。
吸光度の数値が低いほど、インキ成分の移行は少なく、低マイグレーション性能は優れていると判定することができる。
[Evaluation method 2 for printed matter: low migration]
Immediately after producing the printed matter, a polyvinylidene chloride wrap film (Asahi Kasei Chemicals Co., Ltd.) was bonded to the printed surface coated with UV-curable offset black ink, and the conditions were 25 ° C. and pressure 100 kg / cm 2 . A press treatment was performed for 24 hours. Thereby, low molecular weight components such as unreacted photopolymerization initiator and monomer in the black ink migrate (migrate) to the wrap film layer. After the press treatment, the wrap film was peeled off from the printed material, and the absorbance of the wrap film was measured to quantify the ink components migrated to the wrap film. Absorbance measurement was performed in a wavelength range of 200 to 500 nm using JASCO's UV-visible spectrophotometer JASCO V-570.
Photopolymerization initiators have different ultraviolet absorption characteristics depending on their molecular structures. For example, 2-benzyl-2-dimethylamino-1- (4-morpholinophenyl) -butanone-1 is ultraviolet light at a wavelength of about 320 nm. Similarly, 2-hydroxy-1- {4- [4- (2-hydroxy-2-methyl-propionyl) -benzyl] -phenyl} -2-methyl-propan-1-one has an absorption peak. In the vicinity of a wavelength of 260 nm, 2-methyl-1- [4- (methylthio) phenyl] -2-morpholinopropan-1-one is ultraviolet light in the vicinity of a wavelength of 300 nm, and 1-hydroxy-cyclohexyl-phenyl-ketone is in the vicinity of a wavelength of 240 nm. Because it has an absorption peak, it is possible to compare the amount of migration of each initiator by recording the absorbance value at each wavelength. It becomes.
In addition, the ultraviolet absorption peaks of various photopolymerization initiators and acrylate monomers and other compounds overlap and show a high absorbance value in the vicinity of the wavelength of 210 nm. Therefore, even by recording and comparing the absorbance value at the wavelength of 210 nm, the superiority or inferiority of the low migration performance can be obtained. It becomes possible to judge.
It can be determined that the lower the numerical value of absorbance, the less the migration of the ink component, and the lower the migration performance.
