Description

ワニス、オフセット印刷インキ組成物およびオフセット印刷物の製造方法Varnish, offset printing ink composition and method for producing offset printed matter
　本発明は、ワニス、オフセット印刷インキ組成物およびオフセット印刷物の製造方法に関する。 The present invention relates to a varnish, an offset printing ink composition, and a method for producing an offset printed matter.
　オフセット印刷の分野において、環境への負荷を小さくしようとするため、これまで石油系溶剤中の芳香族成分含有率が１重量％未満のアロマフリー溶剤を用いたインキや、揮発性の石油系溶剤を含有しないＮｏｎ－ＶＯＣインキが開発・実用化されてきた。
　近年では、環境配慮型製品として生物由来資源を用いたバイオマスマーク（一般社団法人日本有機資源協会）をオフセット印刷インキでも採用しており、地球温暖化の観点からも、高沸点石油系ではなくバイオマス由来、例えば植物油由来の高沸点溶剤をより多く含有しているインキのニーズが今まで以上に高まっている。これは、持続可能でよりよい世界を目指すという国際的な目標とも合致する。 In the field of offset printing, in order to reduce the burden on the environment, inks using aroma-free solvents containing less than 1% by weight of aromatic components in petroleum-based solvents, and volatile petroleum-based solvents have been used. Non-VOC inks containing no have been developed and put into practical use.
In recent years, the Biomass Mark (Japan Organic Resources Association), which uses biological resources as an environmentally friendly product, has also been adopted for offset printing inks. There is an ever-increasing need for inks containing more high-boiling solvents of origin, such as from vegetable oils. This is also in line with the international goal of striving for a sustainable and better world.
　例えば、特許文献１にはバイオマス由来の脂肪酸エステルを用いたＮｏｎ－ＶＯＣオフセット印刷インキ組成物が提案されている。また、特許文献２には、イソパラフィン類を５０重量％超と、ナフテン類を４０重量％以下とを含む、バイオマス変換由来の生成物に由来した炭化水素系流体が提案され、その炭化水素系流体を、「コールドセット型」新聞用紙オフセットインキ組成物の成分として用いることができるとしている。 For example, Patent Document 1 proposes a Non-VOC offset printing ink composition using a biomass-derived fatty acid ester. Further, Patent Document 2 proposes a hydrocarbon-based fluid derived from products derived from biomass conversion, containing more than 50% by weight of isoparaffins and 40% by weight or less of naphthenes. can be used as a component of a "coldset" newsprint offset ink composition.
特開２０１６－２０４５５７号公報JP 2016-204557 A 特表２０１２－５２０３７０号公報Japanese Patent Publication No. 2012-520370
　しかしながら、特許文献１は、脂肪酸エステルをバイオマス由来としただけで、ＡＦソルベント７号といった石油系高沸点溶剤は従来のオフセット印刷インキと同程度使用されている。特許文献２は、「バイオマス変換由来の生成物に由来した炭化水素系流体」とあるのみで、炭化水素系流体（「石油系高沸点溶剤」と同義と思われる。）に関する「バイオマス変換」について何の説明も、示唆もない。 However, in Patent Document 1, only the fatty acid ester is derived from biomass, and a petroleum-based high-boiling solvent such as AF Solvent No. 7 is used to the same extent as conventional offset printing inks. Patent Document 2 only mentions "a hydrocarbon-based fluid derived from a product derived from biomass conversion", and is about "biomass conversion" regarding a hydrocarbon-based fluid (which seems to be synonymous with "petroleum-based high-boiling-point solvent"). No explanation, no hint.
　オフセット印刷インキでは、普通、石油系高沸点溶剤をインキ全体に対し２０～４５質量％もの量を使用している。オフセット印刷は、一般書籍、新聞などの多量に印刷することの多い印刷物に使用されているため、この石油系高沸点溶剤をバイオマス由来とすることができれば、環境への大きな負荷軽減に繋がる。 In offset printing inks, petroleum-based high-boiling solvents are normally used in an amount of 20 to 45% by mass based on the total amount of ink. Offset printing is used for printed materials that are often printed in large quantities, such as general books and newspapers.
　本発明は、バイオマス由来の溶剤を用いながら石油系溶剤を用いた場合と同等以上の性能を示すワニス、オフセット印刷インキ組成物およびオフセット印刷物の製造方法を提供することを目的とする。
　また、本発明は、石油系溶剤の代わりにバイオマス由来の溶剤を用いることにより、環境負荷を低減した、オフセット印刷インキ組成物およびそれを用いた印刷物の製造方法を提供することを目的とする。 An object of the present invention is to provide a varnish, an offset printing ink composition, and a method for producing an offset printed matter that exhibit performance equal to or greater than that obtained when using a petroleum-based solvent while using a biomass-derived solvent.
Another object of the present invention is to provide an offset printing ink composition with reduced environmental load by using a biomass-derived solvent instead of a petroleum-based solvent, and a method for producing a printed matter using the same.
　本発明者らは、鋭意検討した結果、高沸点溶剤としてバイオマス由来の炭化水素系溶剤を使用することにより、前記課題を解決できることを見出し、本発明を完成した。 As a result of intensive studies, the present inventors found that the above problems could be solved by using a biomass-derived hydrocarbon-based solvent as a high boiling point solvent, and completed the present invention.

＜ワニス＞
　本実施形態に係るワニスは、オフセット印刷インキ組成物に用いられるワニスであって、バイオマス由来で沸点２００℃以上の炭化水素系溶剤を含有する。 <Varnish>
The varnish according to the present embodiment is a varnish used in an offset printing ink composition, and contains a biomass-derived hydrocarbon-based solvent having a boiling point of 200° C. or higher.
　本実施形態に係るバイオマス由来の炭化水素系溶剤としては、例えば、米国Ｎｏｖｖｉ　ＬＬＣ社がバイオマスから製造したα－オレフィンのＮｏｖａＳｏｌｖ　１６０を例示できる。ＮｏｖａＳｏｌｖ　１６０は、１－ヘキサデセン　（含有比率：９５～９９質量％）と、１－オクタデセン（含有比率：１～５質量％）と、を含む混合物である。 As a biomass-derived hydrocarbon-based solvent according to the present embodiment, for example, the α-olefin NovaSolv 160 manufactured from biomass by Novvi LLC in the United States can be exemplified. NovaSolv 160 is a mixture containing 1-hexadecene (content ratio: 95-99% by mass) and 1-octadecene (content ratio: 1-5% by mass).

　本実施形態に係るオフセット印刷インキ組成物においては、前記オフセット印刷インキ組成物１００質量部に対するバイオマス由来で沸点２００℃以上の炭化水素系溶剤の含有量が、機上安定性を向上させる観点から、好ましくは５質量部以上、より好ましくは１０質量部以上、さらに好ましくは１５質量部以上、さらに好ましくは２０質量部以上、さらに好ましくは２５質量部以上、さらに好ましくは３０質量部以上である。
　なお、機上安定性が向上した状態というのは、例えば、下記の＜方法１＞により評価される、タック値がピーク値をむかえるまでに要する時間が長い状態を指す。 In the offset printing ink composition according to the present embodiment, the content of the biomass-derived hydrocarbon solvent having a boiling point of 200° C. or higher with respect to 100 parts by mass of the offset printing ink composition is, from the viewpoint of improving on-press stability, It is preferably 5 parts by mass or more, more preferably 10 parts by mass or more, still more preferably 15 parts by mass or more, still more preferably 20 parts by mass or more, still more preferably 25 parts by mass or more, still more preferably 30 parts by mass or more.
The state in which on-board stability is improved refers to a state in which the time required for the tack value to reach a peak value is long, as evaluated by <Method 1> below, for example.
　本実施形態に係るオフセット印刷インキ組成物においては、下記の＜方法１＞により評価されるタック値がピーク値をむかえるまでに要する時間が、好ましくは２６分間以上、より好ましくは２９分間以上、さらに好ましくは３５分以上、さらに好ましくは４０分以上、さらに好ましくは４５分以上、さらに好ましくは５０分以上である。 In the offset printing ink composition according to the present embodiment, the time required for the tack value evaluated by <Method 1> below to reach a peak value is preferably 26 minutes or longer, more preferably 29 minutes or longer, and It is preferably 35 minutes or longer, more preferably 40 minutes or longer, still more preferably 45 minutes or longer, and still more preferably 50 minutes or longer.
　＜方法１＞
　本実施形態に係るオフセット印刷インキ組成物を、インキ量１．３１ｃｃ、室温２５℃、ローラー温度３５℃、回転数１２００ｒｐｍの条件下で、デジタルインコメーターを回転させ、タック値がピーク値をむかえるまでに要する時間を測定する。 <Method 1>
The offset printing ink composition according to the present embodiment is rotated with a digital incometer under the conditions of an ink amount of 1.31 cc, a room temperature of 25° C., a roller temperature of 35° C., and a rotation speed of 1200 rpm until the tack value reaches a peak value. Measure the time required for
　上記の＜方法１＞による評価について補足すると、上記の＜方法１＞の条件でデジタルインコメーターを回転させると、回転開始とともにタック値が上昇し、ある時点でピーク値をむかえ、その後下降する。このように一度ピーク値をむかえたタック値が下降するのは、ピーク値をむかえた時点で、インコメーターローラー上でインキ剥げが起こっているためである。そのため、タック値がピーク値をむかえるまでに要した時間は、インキ剥げが起こるまでに要した時間であるとみなせる。
　すなわち、タック値がピーク値をむかえるまでに要した時間が長いほど、インキ剥げが起こるまでに要した時間が長い、つまり、機上安定性が高いとみなすことができる。 Supplementing the evaluation by <Method 1> above, when the digital incomometer is rotated under the conditions of <Method 1> above, the tack value increases with the start of rotation, reaches a peak value at a certain point, and then decreases. The reason why the tack value once reaches the peak value and then decreases is that the ink has peeled off on the ink meter roller at the time when the peak value is reached. Therefore, the time required for the tack value to reach the peak value can be regarded as the time required for ink peeling.
That is, the longer the time required for the tack value to reach the peak value, the longer the time required for ink peeling, that is, the higher the on-press stability.
