Description
本発明は、オフセット印刷等に利用することができる印刷用湿し水組成物に関するものである。 The present invention relates to a fountain solution for printing that can be used for offset printing and the like.
オフセット印刷に用いられる印刷版は、画線部と非画線部とが同一平面上に形成されている。そして、画線部は親油性（疎水性）であり、油性インキに対して受理性が高く、水に対して受容性がないように処理されており、一方、非画線部は親水性（疎油性）であり、 水に対して受理性が高く油性インキに対して受容性がないように処理されている。 A printing plate used for offset printing has an image portion and a non-image portion formed on the same plane. And the image area is oleophilic (hydrophobic) and is treated so as to be highly receptive to oil-based ink and not receptive to water, while the non-image area is hydrophilic ( It is treated so that it is highly receptive to water and not receptive to oil-based inks.
このような処理が施された印刷版を用いたオフセット印刷においては、まず印刷版上に湿し水を供給し、親水性の非画線部に均一で薄い水の膜を形成させることが必要である。この薄い水の膜は、油性インキを反発して非画線部への油性インキの付着を防止できるため、非画線部ではこの水膜を完全に形成させることが重要である。印刷版上の非画線部を湿し水で覆った後、更に、油性インキを親油性の画線部のみに転移させ、この印刷版上に形成されたインキ画像は、ブランケット、次いで被印刷体に転移して印刷物が得られる。 In offset printing using a printing plate subjected to such treatment, it is necessary to first supply dampening water onto the printing plate to form a uniform and thin water film on the hydrophilic non-image area. It is. Since this thin water film can repel oil-based ink and prevent the oil-based ink from adhering to the non-image area, it is important to completely form this water film in the non-image area. After the non-image area on the printing plate is covered with fountain solution, the oil-based ink is further transferred only to the oleophilic image area, and the ink image formed on the printing plate is blanket and then printed Transfer to the body to obtain printed matter.
ここで、使用される湿し水は、最も簡単には水であってもよい。しかし、水のみでは、湿し水としての機能を充分満足するものではなく、例えば、湿し水の供給量が少なくなると、インキは容易に非画線部に転移するようになる。そこで、通常、この様な印刷不良を改善するためには、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、且つ局部的に異なる湿し水供給量の差を少なくすることが必要であり、そのために粘度調節剤、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ている。 Here, the fountain solution used may be water most simply. However, the water alone does not sufficiently satisfy the function as the fountain solution. For example, when the supply amount of the fountain solution is reduced, the ink is easily transferred to the non-image area. Therefore, normally, in order to improve such printing defects, the viscosity, pH value and emulsification characteristics for printing ink should be optimized, and the difference in the amount of dampening solution supplied locally should be reduced. Therefore, a viscosity modifier, a hydrophilic agent, a buffering agent, a solubilizing agent, a wetting agent, an antifoaming agent and the like are added and blended.
このような、従来のオフセット印刷に使用される印刷用湿し水組成物では、印刷物に汚れを発生させないように、湿し水の供給量を調整することが非常に困難という問題を有することから、この点を改善するために、イソプロピルアルコールを１〜２０質量％含有する印刷用湿し水組成物も提案されている（例えば、特許文献１参照）。 In such a fountain solution composition used for conventional offset printing, there is a problem that it is very difficult to adjust the supply amount of the fountain solution so as not to cause stains on the printed matter. In order to improve this point, a fountain solution for printing containing 1 to 20% by mass of isopropyl alcohol has also been proposed (for example, see Patent Document 1).
しかしながら、このイソプロピルアルコールは消防法における危険物に該当し、また、労働安全衛生法の有機溶剤中毒予防規則でも規制されており、消防や作業環境といった面で好ましくない。そこで、イソプロピルアルコールの含有量を有機溶剤中毒予防規則の規制値以下（印刷用湿し水組成物中５％質量未満）にまで低減させた印刷用湿し水組成物、更には、イソプロピルアルコールを全く含有しない印刷用湿し水組成物が望まれており、種々の印刷用湿し水組成物の提案がなされている（例えば、特許文献２、特許文献３参照）。 However, this isopropyl alcohol corresponds to a dangerous substance in the Fire Service Law, and is also regulated by the organic solvent poisoning prevention regulations of the Industrial Safety and Health Law, which is not preferable in terms of fire fighting and work environment. Therefore, a fountain solution for printing in which the content of isopropyl alcohol is reduced below the regulation value of the organic solvent poisoning prevention regulations (less than 5% by mass in the fountain solution for printing), and further isopropyl alcohol is added. A fountain solution for printing that does not contain at all is desired, and various fountain solution compositions for printing have been proposed (see, for example, Patent Document 2 and Patent Document 3).
ところが、イソプロピルアルコールは湿し水に良好な性能を付与できる材料であるため、それを減量あるいは除いた湿し水で、従来のオフセット印刷に使用される印刷用湿し水組成物と同じ性能を付与することは困難であり、湿し水供給量の調整を容易にするために、さらに改良する余地があった。 However, since isopropyl alcohol is a material that can impart good performance to dampening water, the dampening water obtained by reducing or eliminating it has the same performance as the conventional dampening water composition used for offset printing. It is difficult to apply, and there is room for further improvement in order to facilitate adjustment of the dampening water supply amount.
本発明の課題は、湿し水からイソプロピルアルコールを減量あるいは除去することにより消防上及び安全衛生面での問題を解決し、印刷作業における湿し水供給量の調整を容易にし、且つ経時での乳化率の低減及び乳化インキ流動性の向上が図れ、印刷物の汚れ、印刷物の濃度変化、ローラーストリップ等の発生をなくすことができる印刷用湿し水組成物を提供することである。 The object of the present invention is to solve the problems on fire fighting and safety and hygiene by reducing or removing isopropyl alcohol from the fountain solution, facilitating adjustment of the dampening water supply amount in the printing operation, and over time. It is an object to provide a fountain solution for printing that can reduce the emulsification rate and improve the fluidity of the emulsified ink and can eliminate the occurrence of stains on the printed matter, changes in the concentration of the printed matter, roller strips, and the like.
本発明者らは、上記課題を解決するため研究を重ねた結果、特定のポリ（オキシエチレン）セチルエーテルを含有させることにより、上記目的を容易に解決できることを見出し、本発明を完成させたものである。本発明の印刷用湿し水組成物を利用すると、イソプロピルアルコールを印刷用湿し水組成物全質量のうち５質量％未満しか使用しない場合、または、未使用の場合においても性能が格段に向上し、上記課題を見事に解決することができることとなる。 As a result of repeated studies to solve the above problems, the present inventors have found that the above object can be easily solved by including a specific poly (oxyethylene) cetyl ether, and have completed the present invention. It is. When the fountain solution for printing of the present invention is used, the performance is greatly improved even when isopropyl alcohol is used less than 5% by mass of the total mass of the fountain solution for printing or when it is not used. Thus, the above problem can be solved brilliantly.

If it is less than 0.0003 mass%, the desired effect may not be sufficiently obtained during printing. The upper limit is 0.1% by mass, preferably 0.08% by mass, and particularly preferably 0.015% by mass. If it exceeds 0.1% by mass, over-emulsification in the ink and a roller strip phenomenon tend to occur.

通常、印刷用湿し水組成物は、製造時に水中に各種含有成分を多量に添加して濃縮状態（高濃度状態）とし、印刷時には希釈されて利用される。そこで、このような場合において上記のポリ（オキシエチレン）セチルエーテルを含有させるには、（Ａ）予め他の成分と共に、濃縮状態の湿し水を作成する時にポリ（オキシエチレン）セチルエーテルを添加する方法、（Ｂ）濃縮状態の液体の作成時、及び、希釈時又は希釈後の両方で湿し水にポリ（オキシエチレン）セチルエーテルを添加する方法、（Ｃ）濃縮状態の印刷用湿し水の作成時にはポリ（オキシエチレン）セチルエーテルは添加せず、希釈時や希釈後に添加する方法等が挙げられるが、最終的な印刷用湿し水組成物に、化学式（１）で表されるポリ（オキシエチレン）セチルエーテルを印刷用湿し水組成物の全質量に基づいて０．０００３質量％以上、０．１質量％以下の範囲となるように含有させることができる方法であればどんな方法でも好適に用いることができる。 Usually, a fountain solution for printing is used in a concentrated state (high concentration state) by adding a large amount of various components in water at the time of manufacture, and diluted at the time of printing. Therefore, in such a case, in order to contain the above poly (oxyethylene) cetyl ether, (A) In addition to the other components, poly (oxyethylene) cetyl ether is added when preparing the fountain solution in a concentrated state.
