Description
本発明はオフセット印刷用インキ組成物に関する。更に詳しくは印刷時には、版面の親油性部分に良好に転移し、親水性部分に転移することが防止され、印刷後は速やかに乾燥することにより、白抜けやカスレ、汚れがなく、保存や後加工も容易な印刷物が得られるオフセット印刷用インキ組成物に関する。 The present invention relates to an ink composition for offset printing. More specifically, during printing, it is well transferred to the oleophilic part of the plate surface and prevented from transferring to the hydrophilic part. After printing, it is dried quickly, so that there are no white spots, smudges, or stains. The present invention relates to an ink composition for offset printing from which a printed material that can be easily processed is obtained.
オフセット印刷は、油性インキが水と反発する性質を利用して、凹凸のない印刷版で印刷することを特徴とした印刷方式である。オフセット印刷版上には親油性の画像部と、親水性の非画像部が形成されている。そして、印刷版に油性インキが供給される前に、湿し水と呼ばれる水性成分が供給され、親水性の非画像部が湿し水で湿潤された状態となっている。その後、油性インキを供給し、親油性の画像部にインキを付着させ、湿し水で湿潤された親水性の非画像部には、油と水との反発からインキを付着させないことにより画像を形成する。 Offset printing is a printing method characterized in that oil-based ink is printed on a printing plate without irregularities by utilizing the property of repelling water. On the offset printing plate, an oleophilic image portion and a hydrophilic non-image portion are formed. Then, before the oil-based ink is supplied to the printing plate, an aqueous component called dampening water is supplied, and the hydrophilic non-image area is wetted with dampening water. After that, oil-based ink is supplied, the ink is adhered to the oleophilic image area, and the hydrophilic non-image area wetted with the fountain solution is not adhered to the hydrophilic non-image area by repelling the oil and water. Form.
従って、オフセット印刷用インキには、基本的な性能として、親油性の画像部に確実に付着し、親水性の非画像部には一切付着しないという両方の性能が要求される。ここで、前者の性能が不足すれば、印刷紙面の本来インキが付着している部分にいわゆる白抜けやカスレを生じる。また、後者の性能が不足すれば印刷紙面の余分なところにもインキが付着して汚れが生じる。オフセット印刷は、特に美粧性が要求される分野で利用される印刷方式であり、上記の白抜け、カスレ、あるいは汚れが少しでも発生すると、目的とする印刷物が得られないことになる。 Accordingly, the ink for offset printing is required to have both of the basic performances of reliably adhering to the oleophilic image area and not adhering to the hydrophilic non-image area at all. Here, if the former performance is insufficient, so-called white spots and blurring occur on the portion of the printing paper surface where the original ink is adhered. In addition, if the latter performance is insufficient, the ink adheres to an excess portion of the printing paper surface and stains occur. Offset printing is a printing method used particularly in the field where cosmetics are required. If the above-described white spots, blurring, or smudges occur even slightly, the intended printed matter cannot be obtained.
更に、美粧印刷物が得られなくなる要因として、印刷紙面の乾燥不良がある。例えば、印刷後、印刷物は巻き取りや積み重ねの状態で保管される。このとき、印刷紙面が乾燥していないと、印刷面と接触している印刷用紙の裏面にインキがとられて印刷物がかすれてしまう。また、裏面に付着したインキが更に印刷面に移行すると、印刷面の汚れとなる。また、オフセット印刷用インキは高粘度であるために、ブロッキング等が発生しやすく、紙剥けの原因ともなる。
加えて、印刷物を重ねて裁断する後加工工程がある場合は、裁断機の刃のあたる部分に力が集中するため、ブロッキングや紙剥けはより起こりやすくなる。Furthermore, a factor that makes it impossible to obtain a cosmetic print is a drying failure of the printing paper surface. For example, after printing, the printed material is stored in a wound or stacked state. At this time, if the printing paper surface is not dry, ink is taken on the back surface of the printing paper that is in contact with the printing surface, and the printed matter is faded. Further, when the ink adhered to the back surface further moves to the printing surface, the printing surface becomes dirty. Further, since the offset printing ink has a high viscosity, blocking or the like is likely to occur, which may cause paper peeling.
In addition, when there is a post-processing step in which the printed material is overlapped and cut, the force concentrates on the portion corresponding to the blade of the cutting machine, so that blocking and paper peeling are more likely to occur.
そこで、印刷後における印刷物の保管や加工等の観点からは、印刷紙面が速やかに乾燥することが望ましい。オフセット印刷の乾燥の方式は、インキの溶剤を熱風等で揮発させることで乾燥する蒸発乾燥方式や、インキの溶剤を用紙に浸透させることで乾燥する浸透乾燥方式が存在する。また他に、インキ中に存在するアマニ油等の不飽和化合物を酸化重合により表面硬化させることで乾燥する酸化重合方式も存在する。 Therefore, from the viewpoint of storage and processing of printed matter after printing, it is desirable that the printed paper surface be quickly dried. There are two types of offset printing drying methods, an evaporation drying method in which the ink solvent is volatilized with hot air or the like, and an infiltration drying method in which the ink solvent is allowed to penetrate into the paper. In addition, there is an oxidative polymerization method in which an unsaturated compound such as linseed oil present in the ink is dried by surface curing by oxidative polymerization.
これらの乾燥方式のうち酸化重合方式においては、乾燥速度を高めるために補助剤として硬化促進剤（ドライヤー）が添加される。一般にドライヤーとしては、マンガン、コバルト等の金属石鹸が使用され、添加量を増加することにより、乾燥速度を向上させることが可能である。しかし、これらの金属石鹸では、一般にオクチル酸等の脂肪酸、ナフテン酸等の酸が、金属イオン封鎖剤として使用されているため、大量に添加するとこれらの酸の含有量も必然的に増加する。 Among these drying methods, in the oxidative polymerization method, a curing accelerator (dryer) is added as an auxiliary agent in order to increase the drying rate. Generally, a metal soap such as manganese or cobalt is used as the dryer, and the drying rate can be improved by increasing the amount of addition. However, in these metal soaps, since fatty acids such as octyl acid and acids such as naphthenic acid are generally used as sequestering agents, the content of these acids inevitably increases when added in large amounts.
特に、このドライヤー中に含まれるオクチル酸等の脂肪酸は、親油基である長鎖アルキル基と、親水基であるカルボキシル基とを併せ持つため、印刷版の親水性、親油性のどちらの部分とも吸着が可能である。これらの酸が、前記印刷版上の非画像部（親水性）に吸着すると、吸着部の表面で配向している長鎖アルキル基によって、もともと親水性であったはずの印刷版の非画像部が親油化されてしまうことになる。その結果として、印刷版の非画像部には水ではなくインキが付着するようになって、印刷紙面の汚れを生じることになる。従って、ドライヤーとして金属石鹸を使用する場合には、少ないときは乾燥不良となる。一方、使用量が多いときは、乾燥性は向上しても、版面の親水性部分の親油性化により印刷時に汚れが発生する。このため、ドライヤーの使用量が制限され、目的とする乾燥性が充分に得られない場合が有った。 In particular, fatty acids such as octylic acid contained in this dryer have both a long-chain alkyl group, which is a lipophilic group, and a carboxyl group, which is a hydrophilic group. Adsorption is possible. When these acids are adsorbed to the non-image area (hydrophilic) on the printing plate, the non-image area of the printing plate that should have been originally hydrophilic by the long-chain alkyl group oriented on the surface of the adsorption area Will be made oleophilic. As a result, the ink adheres to the non-image area of the printing plate instead of water, and the printing paper surface is stained. Therefore, when metal soap is used as a dryer, if it is small, it becomes poorly dried. On the other hand, when the amount used is large, even if the drying property is improved, stains occur during printing due to the lipophilicity of the hydrophilic portion of the plate surface. For this reason, the use amount of the dryer is limited, and the desired drying property may not be obtained sufficiently.
印刷紙面の汚れを軽減するために、従来、ロジンのアルキレンオキシド付加物を用いる（例えば、特許文献１参照）、炭素原子の総数が４以上である未置換又は置換されたアルキレンオキサイド単位を有し、平均分子量が４００以上の化合物を用いる（例えば、特許文献２参照）、アルキレンオキシド単位を有し、ＨＬＢ値が３〜１３の化合物を用いる（例えば、特許文献３参照）等の方法により、インキと湿し水との乳化調整を行う方法が開示されている。この方法は、油性成分と水性成分との界面での反発の度合いを、印刷条件に合わせて最適とするものである。確かに、印刷版の非画像部により多くの水を供給するために、上記の乳化状態を調整することは汚れを軽減するのに有効である。しかしながら、前記の通り、そもそも印刷版の非画像部が親油化してしまった状態では、これらの方法を利用してもほとんど効果は無いものであった。 In order to reduce stains on the printed paper, conventionally, an alkylene oxide adduct of rosin is used (see, for example, Patent Document 1), which has an unsubstituted or substituted alkylene oxide unit having a total number of carbon atoms of 4 or more. By using a compound having an average molecular weight of 400 or more (for example, see Patent Document 2), using a compound having an alkylene oxide unit and having an HLB value of 3 to 13 (for example, see Patent Document 3) Discloses a method for adjusting emulsification between water and fountain solution. This method optimizes the degree of repulsion at the interface between the oily component and the aqueous component in accordance with the printing conditions. Certainly, in order to supply more water to the non-image area of the printing plate, adjusting the above emulsified state is effective in reducing dirt. However, as described above, in the first place, when the non-image part of the printing plate has been made oleophilic, even if these methods are used, there is almost no effect.
また、印刷用インキ組成物にアスコルビン酸を添加する発明が開示されている（例えば、特許文献４参照）。しかし、これはアスコルビン酸の持つ酸化防止作用に着目して、もっぱらアスコルビン酸を印刷インキの酸化防止剤として添加しているにすぎない。また、アスコルビン酸を使用していることに起因して、印刷物の非画像部（無地部）に汚れが生じるという問題もある。 Moreover, the invention which adds ascorbic acid to a printing ink composition is disclosed (for example, refer patent document 4). However, this pays attention to the antioxidant action of ascorbic acid, and only ascorbic acid is added as an antioxidant for printing ink. In addition, there is also a problem that the non-image portion (solid portion) of the printed matter is stained due to the use of ascorbic acid.
このようにオフセット印刷の分野では、ドライヤーにより乾燥性を向上させる方法を用いながら、印刷紙面の汚れを防止する材料、技術が切望されている。
本発明は、このような従来技術の課題を解決するためになされたものである。即ち、印刷紙面の充分な乾燥性を有しつつ、印刷紙面の汚れのトラブルの軽減を図ることが出来るオフセット印刷用インキ組成物を提供することを目的とする。このような目的は、オフセット印刷用インキ組成物の乾燥性を向上するのに充分な量の金属石鹸をドライヤーとして添加した場合であっても、金属石鹸に含まれる脂肪酸等の酸の印刷版上の非画像部への付着を防止することで非画像部が親油化するのを防止することによって達成することができる。 The present invention has been made to solve such problems of the prior art. That is, an object of the present invention is to provide an ink composition for offset printing, which can reduce the problem of stains on the printing paper surface while having sufficient drying properties on the printing paper surface. Even if such a purpose is to add a sufficient amount of metal soap as a dryer to improve the drying property of the ink composition for offset printing, it can be used on the printing plate of acids such as fatty acids contained in the metal soap. This can be achieved by preventing the non-image portion from becoming lipophilic by preventing the non-image portion from adhering to the non-image portion.
本発明者らは前記の課題を解決するために鋭意検討した。その結果、金属石鹸をドライヤーとして含有するオフセット印刷用インキ組成物に対して、酸又は酸の塩を添加する方法が有効であることを見出し、本発明を完成するに至った。 The present inventors diligently studied to solve the above problems.

以下、本発明のオフセット印刷用インキ組成物（以下、単に「インキ組成物」ともいう）について更に詳細に説明する。
上記の通り、本発明はインキ組成物に対して、無機ないし有機の酸及び／又はこれらの酸の塩を添加して、金属石鹸型ドライヤーを添加することに伴う印刷紙面の汚れを取り除くことを目的とするものである。Hereinafter, the ink composition for offset printing of the present invention (hereinafter, also simply referred to as “ink composition”) will be described in more detail.
As described above, the present invention adds an inorganic or organic acid and / or a salt of these acids to the ink composition to remove stains on the printing paper surface due to the addition of a metal soap dryer. It is the purpose.
本発明のインキ組成物を構成する酸やその塩〔成分（Ｅ）〕は、（ｉ）親水性の非画像部に吸着した時に、吸着面が湿し水で湿潤される性質を有するものである。また更に、本発明のインキ組成物は、（ｉｉ）湿し水とインキ組成物とが混和された際に、時間の経過とともに当該湿し水を着色させない性質を有するものである。 The acid or salt thereof (component (E)) constituting the ink composition of the present invention has the property that (i) the adsorption surface is moistened with dampening water when adsorbed on a hydrophilic non-image area. is there. Furthermore, the ink composition of the present invention has a property that (ii) when the dampening water and the ink composition are mixed, the dampening water is not colored over time.
本発明で使用される酸及び／又は酸の塩は、上記（ｉ）の性質を有していることにより、以下に述べる作用効果が発揮され、印刷紙面の汚れが防止されると推察される。
オフセット印刷中において、インキ組成物は、親油性の画像部だけでなく、湿し水で湿潤された状態となっている親水性の非画像部にも接触することになる。そしてこの接触時に、インキ組成物中に含まれる金属石鹸型ドライヤー（オクチル酸金属塩等）に由来する長鎖脂肪酸等の酸（金属封鎖剤）が非画像部に供給された湿し水に溶出する。そのため、特に循環型の湿し水供給装置を利用している印刷方式では、徐々に湿し水中の長鎖脂肪酸等の酸の濃度が高くなる。Since the acid and / or acid salt used in the present invention has the property (i) above, it is presumed that the following effects are exhibited and the printing paper surface is prevented from being stained. .
During offset printing, the ink composition comes into contact with not only the oleophilic image area but also the hydrophilic non-image area wetted with the fountain solution. At the time of this contact, an acid such as a long chain fatty acid (metal sequestering agent) derived from a metal soap dryer (such as a metal salt of octylic acid) contained in the ink composition is eluted in the dampening water supplied to the non-image area. To do. Therefore, particularly in a printing method using a circulation type dampening water supply device, the concentration of acids such as long chain fatty acids in the dampening water gradually increases.
印刷時において、版面に供給された湿し水は、絶えず蒸発するため、非画像部の水膜が薄くなり、かなりの乾燥状態まで進むことになる。このような状態で、金属封鎖剤として長鎖脂肪酸が使用された場合、湿し水に溶出した長鎖脂肪酸のカルボキシル基が非画像部にイオン的に吸着し、その外側に長鎖炭化水素基（長鎖アルキル基等）配向する。このため、非画像部における吸着部（長鎖化水素基の配向部位）については、表面が親水性から親油性に変化する。従来のインキ組成物には、この吸着を阻害する材料が含まれていないため、親油化が継続して進むことにより、非画像部にインキ組成物が付着し、その結果、印刷紙面の汚れが生じていた。 At the time of printing, the fountain solution supplied to the printing plate constantly evaporates, so the water film in the non-image area becomes thin and proceeds to a considerably dry state. In such a state, when a long-chain fatty acid is used as a metal sequestering agent, the carboxyl group of the long-chain fatty acid eluted in the fountain solution is ionically adsorbed on the non-image area, and a long-chain hydrocarbon group is formed on the outside. Oriented (long chain alkyl group, etc.). For this reason, about the adsorption | suction part (orientation site | part of a long-chain hydrogen group) in a non-image part, the surface changes from hydrophilicity to lipophilicity. Since the conventional ink composition does not contain any material that inhibits this adsorption, the ink composition adheres to the non-image area as the oleophilic process continues, resulting in smudges on the printing paper surface. Has occurred.
これに対して、本発明で使用される酸及び／又は酸の塩は、親水性の非画像部に吸着した時に、吸着面が湿し水で湿潤される性質を有している。この性質は、酸及び／又は酸の塩が溶解した溶液等を用いて、オフセット印刷版上の非画像部に、酸及び／又は酸の塩をイオン的に吸着させた時に、その吸着面（非画像部における酸及び／又は酸の塩が吸着している部位）が、更に供給される湿し水によって湿潤され、親水性の状態となる性質を意味する。 On the other hand, the acid and / or acid salt used in the present invention has a property that the adsorption surface is moistened with dampening water when adsorbed on the hydrophilic non-image area. This property is obtained when the acid and / or salt of the acid is ionically adsorbed on the non-image area on the offset printing plate using a solution in which the acid and / or acid salt is dissolved. This means that the portion of the non-image area where the acid and / or acid salt is adsorbed) is further wetted by the supplied dampening water and becomes hydrophilic.
このような性質を有する酸及び／又は酸の塩は親水性が高い。このため、この成分と、長鎖脂肪酸を金属封鎖剤とする金属石鹸型ドライヤーとを含むインキ組成物が非画像部に供給された湿し水と接触すると、この酸及び／又は酸の塩が長鎖脂肪酸に先立って溶出する。その結果、非画像部の水膜が乾燥状態になった際に、上記酸及び／又は酸の塩が長鎖脂肪酸より先に非画像部に吸着する。また、上記酸及び／又は酸の塩は、親水性の非画像部との吸着性が長鎖脂肪酸より高いため、先に長鎖脂肪酸が吸着しても、その長鎖脂肪酸が高い親水性を有する酸及び／又は酸の塩に置き換わることも考えられる。 Acids and / or acid salts having such properties are highly hydrophilic. For this reason, when an ink composition containing this component and a metal soap type dryer using a long-chain fatty acid as a metal sequestering agent comes into contact with the fountain solution supplied to the non-image area, the acid and / or acid salt is formed. Elutes prior to long chain fatty acids. As a result, when the water film in the non-image area is in a dry state, the acid and / or acid salt is adsorbed to the non-image area prior to the long-chain fatty acid. In addition, since the acid and / or salt of the acid has higher adsorptivity with the hydrophilic non-image part than the long chain fatty acid, even if the long chain fatty acid is adsorbed first, the long chain fatty acid has high hydrophilicity. It is also conceivable to replace the acid and / or salt of the acid with it.
このように、たとえ、非画像部の水膜が乾燥状態になっても、高い親水性を有する酸及び／又は酸の塩が版面の非画像部に吸着し、長鎖脂肪酸の吸着が阻害されているため、非画像部全体の親水性が維持される。これにより、酸及び／又は酸の塩の吸着部位を含む非画像部全体が、更に供給された湿し水によって湿潤され、親水性の状態となる。従って、インキ組成物の付着が防止され、その結果、印刷紙面の汚れを防止することができる。 In this way, even when the water film of the non-image area is in a dry state, the acid and / or acid salt having high hydrophilicity is adsorbed on the non-image area of the plate surface, and the adsorption of long chain fatty acids is inhibited. Therefore, the hydrophilicity of the entire non-image part is maintained. Thereby, the whole non-image part including the adsorption site of the acid and / or the salt of the acid is further wetted by the supplied fountain solution and becomes hydrophilic. Therefore, adhesion of the ink composition is prevented, and as a result, the printing paper surface can be prevented from being stained.
また、本発明で使用される酸及び／又は酸の塩は、上記（ｉｉ）の性質を有しているため、以下に述べる作用効果が発揮され、印刷紙面の汚れが防止されると推察される。
ところで上記特許文献４に開示されている印刷用インキ組成物は、アスコルビン酸を酸化防止剤として添加するものである。しかし、酸としてアスコルビン酸を使用すると、以下の理由により本発明の目的を達成することが出来ない。In addition, since the acid and / or acid salt used in the present invention has the property (ii), it is presumed that the following effects are exhibited and stains on the printing paper surface are prevented. The
By the way, the ink composition for printing currently disclosed by the said patent document 4 adds ascorbic acid as antioxidant. However, when ascorbic acid is used as the acid, the object of the present invention cannot be achieved for the following reasons.
インキ組成物に添加されたアスコルビン酸は、湿し水と接触した場合に湿し水に溶出し、なおかつ溶出したアスコルビン酸は空気酸化によって黒色に着色する。版面の非画像部に付着した湿し水は、最終的に印刷物の非画像部（無地部）に転移する。よって、上記のように湿し水が着色していると、無地部が全く意図しない色に着色（汚損）することになる。本発明は、もともと、ドライヤーの添加に伴って発生する非画像部へのインキの付着の防止、すなわち、無地部の汚損を防止することを目的とするものである。このため、湿し水で汚損される（例えば、アスコルビン酸を利用した場合は無地部が黒ずんだようになり、印刷物の見栄えを極端に悪くする）と本発明の効果は喪失する。
従って、酸及び／又は酸の塩が上記（ｉ）の性質を有していても、それだけでは、このような問題まで解消できず、印刷紙面に汚れが生じてしまう。Ascorbic acid added to the ink composition is eluted into the dampening water when it comes into contact with the dampening water, and the eluted ascorbic acid is colored black by air oxidation. The fountain solution adhering to the non-image area of the printing plate finally transfers to the non-image area (plain area) of the printed material. Therefore, when the fountain solution is colored as described above, the solid color portion is colored (stained) in an unintended color. An object of the present invention is to prevent ink from adhering to a non-image area, which is generated with the addition of a drier, that is, to prevent soiling of a plain area. For this reason, the effect of the present invention is lost when it is fouled with fountain solution (for example, when ascorbic acid is used, the plain portion becomes dark and the appearance of the printed matter is extremely deteriorated).
Therefore, even if the acid and / or the salt of the acid has the above-mentioned property (i), such a problem cannot be solved by itself, and the printing paper surface is stained.
本発明で使用される酸及び／又は酸の塩は、湿し水とインキ組成物とが混和された際に、時間の経過とともに当該湿し水を着色させない性質を有している。この性質は、オフセット印刷において、使用される湿し水と、上記酸及び／又は酸の塩を含む本発明のオフセット印刷用インキ組成物とを混和した際に、時間の経過によって、混和された湿し水が、酸及び／又は酸の塩に起因して着色されることがない性質を意味する。 The acid and / or salt of the acid used in the present invention has a property of preventing the fountain solution from being colored over time when the fountain solution and the ink composition are mixed. This property was mixed with the lapse of time when the dampening water used in offset printing and the ink composition for offset printing of the present invention containing the acid and / or salt of the acid were mixed. It means the property that the fountain solution is not colored due to the acid and / or the salt of the acid.
上述したとおり、上記酸及び／又は酸の塩は、オフセット印刷の際、インキ組成物と非画像部の湿し水との接触により、湿し水中に溶出し、版面の非画像部に付着する。そして、付着した酸及び／又は酸の塩は、印刷物の無地部に転移することになるが、上記（ｉｉ）の性質を有していると、湿し水が着色されることがない。このため、湿し水が印刷物の無地部に転移した際にも、無地部が汚損されることを防止することができる。即ち、本発明は、このような湿し水の着色の起こる要因を排除するために、湿し水とインキ組成物とが混和された際に、時間の経過とともに湿し水が着色することがないことを必須要件とするものである。従って、アスコルビン酸を含有したインキ組成物は本発明のインキ組成物には該当しない。なお、上記特許文献４にはアスコルビン酸が金属石鹸型ドライヤーの使用によって生じる汚れを防止する旨の記載は一切無い。 As described above, the acid and / or the salt of the acid is eluted in the fountain solution and adheres to the non-image area of the printing plate by the contact between the ink composition and the fountain solution of the non-image area during offset printing. . And the adhering acid and / or acid salt will be transferred to the plain part of the printed matter, but the dampening solution will not be colored if it has the property (ii). For this reason, even when dampening water transfers to the plain part of printed matter, it can prevent that a plain part is soiled. That is, according to the present invention, when the dampening water and the ink composition are mixed, the dampening water may be colored with the passage of time in order to eliminate the cause of the coloring of the dampening water. It is an essential requirement not to exist. Therefore, the ink composition containing ascorbic acid does not correspond to the ink composition of the present invention. In addition, the above Patent Document 4 has no description that ascorbic acid prevents contamination caused by the use of a metal soap type dryer.
上記酸及び／又は酸の塩において、上記（ｉ）の性質を有するとの要件は、以下の方法１により判断できる。
（方法１）
実際に印刷で使用する版の非画像部に、酸及び／又は酸の塩５ｇをその酸及び／又は酸の塩を溶解できる適度な溶媒９５ｇに溶解させて得られた溶液を、噴霧装置やコーター等の手段で塗工し（塗工量２０ｇ／ｍ２）、室温で乾燥させて酸及び／又は酸の塩を吸着させる。次いで、実際に印刷で使用する湿し水を噴霧装置やコーター等の手段で供給した時の非画像部の状態から判断できる（非画像部における湿し水の供給量１０ｇ／ｍ２）。この時、非画像部が湿し水の連続した破れの無い皮膜で覆われている状態ならば、当該酸及び／又は酸の塩は上記（ｉ）の性質を有すると判断できる。一方、湿し水の皮膜に破れを生じて、連続した皮膜となっていない場合には、当該酸及び／又は酸の塩は上記（ｉ）の性質を有さないと判断される。The requirement that the acid and / or the salt of the acid have the property (i) can be determined by the following method 1.
(Method 1)
A solution obtained by dissolving 5 g of acid and / or salt of acid in 95 g of an appropriate solvent capable of dissolving the acid and / or salt of acid in a non-image portion of a plate actually used in printing is used as a spray device or Coating is performed by means such as a coater (coating amount 20 g / m 2 ), and drying is performed at room temperature to adsorb the acid and / or acid salt. Next, it can be judged from the state of the non-image area when the dampening water actually used for printing is supplied by means of a spraying device or a coater (a supply amount of dampening water in the non-image area is 10 g / m 2 ). At this time, if the non-image area is covered with a continuous film without damaging water, it can be determined that the acid and / or the salt of the acid has the property (i). On the other hand, when the film of the fountain solution is torn and does not form a continuous film, it is determined that the acid and / or salt of the acid does not have the property (i).
また、上記酸及び／又は酸の塩において、上記（ｉｉ）の性質を有するとの要件は、以下の方法２により判断できる。

酸及び／又は酸の塩を含有させた本発明のインキ組成物５０ｇと、実際に印刷で使用する湿し水１００ｇとを、デューク乳化試験機（Ｄｕｋｅ乳化試験機：ＩＮＫ−ＷＡＴＥＲ ＥＭＵＬＳＩＦＩＣＡＴＩＯＮ ＴＥＳＴＥＲ， ＤＵＫＥ ＣＵＳＴＯＭ ＳＹＳＴＥＭＳ ＩＮＣ． ＭＯＤＥＬ Ｄ−１０Ｅ）に仕込んだ後、３０分間混合し、容器に残った湿し水を別容器にて室温で２週間経過させた後の湿し水の着色の有無から判断できる。すなわち、湿し水が混合直後の色調から変化していれば、湿し水は着色していると判断される。一方、混合直後の色調から変化が無ければ着色していないと判断される。混合直後の色調から変化する場合には、多くの場合、無色透明であった溶液が褐色や黒褐色を呈する程度まで変化するので、目視にて容易に判定できる。The requirement that the acid and / or the salt of the acid have the property (ii) can be determined by the following method 2.
(Method 2)
50 g of the ink composition of the present invention containing an acid and / or an acid salt and 100 g of dampening water actually used for printing were added to a Duke emulsification tester (INK-WATER EMULSIFITION TESTER, DUKE). CUSTOM SYSTEMS INC. MODEL D-10E), mixed for 30 minutes, and can be judged from the presence or absence of coloring of the dampening water after 2 weeks of dampening water remaining in the container at room temperature. . That is, if the fountain solution has changed from the color tone immediately after mixing, it is determined that the fountain solution is colored. On the other hand, if there is no change from the color tone immediately after mixing, it is determined that the color is not colored. In the case of changing from the color tone immediately after mixing, in many cases, the solution, which has been colorless and transparent, changes to such an extent that it exhibits brown or black-brown color.
なお、上記酸及び／又は酸の塩が上記（ｉ）、（ｉｉ）の性質を有するかどうかの判断は、上述した方法以外に、実際に印刷を行って確認することも可能である。 In addition, the judgment whether the said acid and / or the salt of an acid have the property of said (i) and (ii) can also be confirmed by actually printing other than the method mentioned above.
上記（ｉ）、（ｉｉ）の性質を有するか否かについて、上記方法１、２による判断は、オフセット印刷において、実際に使用する湿し水を用いて行われる。実際に印刷に使用する湿し水を用いて酸及び／又は酸の塩が（ｉ）及び（ｉｉ）の性質を有することが確認された場合、その酸及び／又は酸の塩を含むインキ組成物を用いてオフセット印刷を行うと、印刷紙面の汚れを充分に防止することができる。 Whether or not it has the properties (i) and (ii) is determined by the dampening water that is actually used in the offset printing. When it is confirmed that the acid and / or the salt of the acid have the properties (i) and (ii) using the dampening water actually used for printing, the ink composition containing the acid and / or the salt of the acid When offset printing is performed using an object, it is possible to sufficiently prevent stains on the printing paper surface.
上記湿し水としては特に限定されず、従来からオフセット印刷に使用されている公知のものを使用することができる。最も簡単には水であってもよい。しかし、水のみでは、印刷不良が生じ、湿し水としての機能が充分満足されない。このため、通常、湿し水の粘度、ｐＨ値や印刷インキに対する乳化特性を最適にし、かつ、局部的に異なる水量の差によって生じる欠陥を防止する目的で、湿し水としては、粘度調節親水性化剤、緩衝剤、溶解助剤、湿潤剤、消泡剤等が添加配合されたものが使用されている。 The fountain solution is not particularly limited, and known ones conventionally used for offset printing can be used. The simplest is water. However, with water alone, defective printing occurs, and the function as a fountain solution is not fully satisfied. Therefore, for the purpose of optimizing the viscosity, pH value and emulsification characteristics for printing ink, and preventing defects caused by locally different amounts of water, the dampening water is generally used as a viscosity-adjusting hydrophilic agent. A material containing a compounding agent, buffering agent, solubilizing agent, wetting agent, antifoaming agent and the like is used.
上記酸及び／又は酸の塩としては、上記（ｉ）及び（ｉｉ）の性質を有するものであれば特に限定されず、例えば、オキソ酸と呼ばれる無機酸又は有機酸やその塩がこのような性質を有する成分として例示される。上記オキソ酸とは、酸素酸ともいいプロトンとして解離し得る水素が酸素原子に結合した酸である。 The acid and / or acid salt is not particularly limited as long as it has the above properties (i) and (ii), and examples thereof include inorganic acids or organic acids called oxo acids and salts thereof.

In the organic acid, when the number of carbons increases and the lipophilicity increases, the effect of preventing soiling tends to gradually decrease. In particular, in the case of a monovalent carboxylic acid, when the number of carbon atoms is 8 or more, the antifouling effect is significantly reduced. Therefore, the organic acid is preferably a compound having less than 8 carbon atoms, more preferably a compound having 6 or less carbon atoms, still more preferably a compound having 3 to 6 carbon atoms, and particularly preferably citric acid.
