Abstract
Description
本発明は平版印刷に用いられる湿し水組成物、及びそれを用いた印刷物の製造方法に関する。 The present invention relates to a fountain solution composition used for lithographic printing and a method for producing a printed matter using the composition.
凹凸のない平面状の印刷版を用い、水と油が反発する性質を利用して油性インキを印刷する平版（オフセット）印刷方式は、商業、雑誌、書籍、新聞などの印刷用途で主流となっている。この印刷方式で用いられる、平面状の印刷版は、親油化処理された樹脂層からなる画線部と、親水化処理された非画線部とからなり、印刷時に、湿し水組成物または湿し水濃縮組成物（エッチ液）と呼ばれる水性成分が印刷版面に供給され、前記非画線部が均一な薄い水膜で保護される。その後、親油性である油性インキを供給すると、湿し水組成物と油性インキの反発が起き、画線部のみにインキを転移させることができる。その結果、平面状の印刷版でありながら、高精細な印刷物が得られる。 The lithographic (offset) printing method, which uses a flat printing plate with no unevenness and uses the repulsive property of water and oil to print oil-based ink, has become the mainstream for printing applications such as commerce, magazines, books, and newspapers. ing. The flat printing plate used in this printing method is composed of an image-forming part composed of a resin layer subjected to lipophilicity treatment and a non-image-forming part subjected to hydrophilization treatment. Alternatively, an aqueous component called a fountain solution concentrated composition (etching solution) is supplied to the printing plate surface to protect the non-image area with a uniform thin water film. After that, when the lipophilic oil-based ink is supplied, repulsion between the dampening water composition and the oil-based ink occurs, and the ink can be transferred only to the image area. As a result, a high-definition printed matter can be obtained even though it is a flat printing plate.
このときに使用される湿し水組成物は水そのものであってもよいが、その場合、前記湿し水組成物に要求される性能を充分に満たすことは難しい。よって一般的には、湿し水組成物として、酸及びその塩類、塩基及びその塩類、界面活性剤、湿潤性水溶性樹脂といった各種添加剤を水に配合し、粘度、表面張力、及びｐＨを調整して使用される。また湿し水濃縮組成物を製造した場合は、その濃度に応じて水で希釈して使用される。 The dampening water composition used at this time may be water itself, but in that case, it is difficult to sufficiently satisfy the performance required for the dampening water composition. Therefore, generally, as a fountain solution composition, various additives such as an acid and its salts, a base and its salts, a surfactant, and a wettable water-soluble resin are mixed with water to adjust the viscosity, surface tension, and pH. Used after adjusting. When a fountain solution concentrated composition is produced, it is diluted with water according to its concentration before use.
一方で、実印刷時の印刷版面上では、湿し水組成物と油性インキとが接触する箇所において、両者の乳化現象の発生は避けられない。長時間、印刷諸適性に優れた、トラブルレスな印刷を実現するためには、湿し水組成物の観点からも、平版インキ組成物に対して適切な乳化特性を付与する必要があり、広い水幅で好適な乳化状態を維持できることが好ましい。 On the other hand, on the printing plate surface during actual printing, the occurrence of the emulsification phenomenon between the dampening water composition and the oil-based ink is inevitable. In order to achieve trouble-free printing with excellent printing suitability for a long time, it is necessary to impart appropriate emulsifying properties to the lithographic ink composition from the viewpoint of the fountain solution composition as well. It is preferable that a suitable emulsified state can be maintained in the water width.
また一般に新聞輪転機等では、印刷機上の湿し水装置からスプレー噴射等により、湿し水組成物を細かい霧状にしてノズルより吹きかけ、水棒ローラーへと供給する。このようなスプレー方式では、ローラー、ノズル、ベアリング、配管、版、電磁弁などの印刷機あるいは付属の金属部品が、長時間、湿し水組成物と接触することになる。その結果、ニッケルメッキ鋼、クロムメッキ鋼、銅、アルミニウム、ステンレスなどからなる前記金属部品は、湿し水組成物により腐食され易い。湿し水組成物による腐食により損傷した部品は、定期的に交換しなければならない。 Further, generally, in a newspaper rotary press or the like, the dampening water composition is sprayed from a dampening water device on a printing machine to form a fine mist, which is sprayed from a nozzle and supplied to a water bar roller. In such a spray method, a printing machine such as rollers, nozzles, bearings, piping, plates, solenoid valves, or attached metal parts come into contact with the fountain solution composition for a long time. As a result, the metal parts made of nickel-plated steel, chrome-plated steel, copper, aluminum, stainless steel, etc. are easily corroded by the fountain solution composition. Parts damaged by corrosion from the fountain solution composition must be replaced on a regular basis.
このような背景のもと、一般的に使用される湿し水組成物はｐＨ５．０前後と酸性のものである（特許文献１参照）。また酸性の湿し水組成物には、整面作用が高いという特徴がある。水溶性の高分子であるアラビアゴム、及び、リン酸及びその塩類などが配合されており、前記アラビアゴムに含まれるアラビノースが、リン酸の作用でアラビン酸となり、非画線部に強固な親水化層を形成することで、整面作用が高まるためである。しかしながらアラビアゴムは腐敗しやすく、スプレー方式の給水機構ではノズル詰まりなどが発生しやすい。また酸性の湿し水組成物は、金属酸化・腐食による錆が発生しやすいといった問題点もある。 Under such a background, the fountain solution composition that is generally used has an acidic pH of around 5.0 (see Patent Document 1). The acidic fountain solution composition is also characterized by a high leveling effect. Gum arabic, which is a water-soluble polymer, and phosphoric acid and its salts are compounded, and the arabinose contained in the gum arabic turns into arabic acid by the action of phosphoric acid, giving a strong hydrophilicity to non-image areas. This is because the surface-arranging action is enhanced by forming the chemical conversion layer. However, gum arabic tends to rot and nozzle clogging is likely to occur in the spray type water supply mechanism. In addition, the acidic dampening water composition has a problem that rust easily occurs due to metal oxidation and corrosion.
一方、アルカリ性の湿し水組成物は、酸性の湿し水組成物と比べて、腐敗しにくく、金属の防錆性にも優れる傾向がある。しかしながら、アラビン酸の形態をとれないことから、整面効果の高いアラビアゴムが使用できない。そこで一般には、アラビアゴムの代わりに、リン酸塩、ケイ酸塩、炭酸塩などを主成分として、さらに界面活性剤、グリコール、水溶性高分子化合物が配合されるものの、整面効果は十分なものとはいえない。整面効果を高めるために、前記成分の種類や量を調整すると、今度は防錆性が悪化する、という問題が生じてしまう。 On the other hand, the alkaline dampening water composition tends to be less likely to rot and has excellent rust preventive properties for metals, as compared with the acidic dampening water composition. However, gum arabic acid, which has a high leveling effect, cannot be used because it cannot take the form of arabic acid. Therefore, generally, instead of gum arabic, a phosphate, a silicate, a carbonate, etc. are contained as a main component, and further a surfactant, glycol, and a water-soluble polymer compound are mixed, but the surface-adjusting effect is sufficient. Not a thing. If the types and amounts of the above components are adjusted in order to enhance the surface leveling effect, then there arises a problem that the rust prevention property deteriorates.
過去にもアルカリ性の湿し水組成物に関しては検討が行われており、例えば特許文献２には、１，２−ベンズイソチアゾリン−３−オンを含有する、ｐＨ１０〜１３．５の印刷用湿し水濃縮液が記載されている。しかしながら評価結果は後述するが、本発明者が評価したところ、１，２−ベンズイソチアゾリン−３−オンを含むだけでは、湿し水組成物の防腐性が十分なものとはならないことが判明した。 Alkaline fountain solution compositions have been studied in the past, and, for example, Patent Document 2 discloses a fountain solution containing 1,2-benzisothiazolin-3-one and having a pH of 10 to 13.5. A water concentrate is described. However, although the evaluation results will be described later, when the present inventor evaluated, it was found that the preservative property of the fountain solution composition was not sufficient only by including 1,2-benzisothiazolin-3-one. ..
また特許文献３には、リンゴ酸金属塩を含有し、かつ、アンモニア、アンモニウム化合物、亜硝酸化合物、硝酸化合物を含有しない平版印刷用湿し水組成物が開示されている。しかしながらそれらの湿し水組成物は、整面性、汚れ耐性、濃度変動耐性などの印刷諸適性が十分なものとはいえなかった。またそもそも特許文献３には、湿し水組成物のｐＨが９以上であると、印刷版の画線が溶解してしまう可能性があるとの記載もある。 Patent Document 3 discloses a fountain solution composition for lithographic printing containing a malic acid metal salt and containing no ammonia, ammonium compound, nitrite compound or nitric acid compound. However, these fountain solution compositions cannot be said to have sufficient printing suitability such as surface smoothness, stain resistance, and density fluctuation resistance. In the first place, Patent Document 3 also describes that if the pH of the fountain solution composition is 9 or more, the image lines of the printing plate may be dissolved.
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り、その目的は、印刷機及び付属設備の金属類に対する腐食が少なく（防錆性に優れる）、平版印刷時の印刷諸適性、すなわち、整面性、汚れ耐性、及び濃度変動耐性に優れ、さらには長期間保存ないし使用しても腐敗することのない（防腐性に優れる）、平版印刷用の湿し水組成物を提供することである。 The present invention has been made in order to solve the problems of the prior art, and its object is to reduce corrosion of the printing machine and auxiliary equipment to metals (excellent in rust prevention), A fountain solution composition for lithographic printing, which has excellent printing suitability, namely surface smoothness, stain resistance, and concentration fluctuation resistance, and does not rot even after long-term storage or use (excellent antiseptic property).

まず、本発明の平版印刷用湿し水組成物を構成する硝酸塩類に関して述べる。
硝酸塩類は、整面剤として機能する上、金属類、特にアルミニウムに対する防錆の観点からも好適に選択されるものである。
本発明では、硝酸塩類として、硝酸塩、亜硝酸塩、亜硝酸化合物からなる群より選択される１種以上が使用できる。

上記の中でも、印刷版への影響が少なく、整面性等の印刷諸適性に優れた平版印刷用湿し水組成物が得られる点から、硝酸ナトリウム、硝酸カリウム、硝酸アンモニウムが好ましい。中でも、硝酸アンモニウムを平版印刷用湿し水組成物に添加すると、印刷停止した後に印刷を再開した際、アルミニウム基板である印刷版の酸化が抑えられ、印刷物に点状の汚れ（酸化汚れ）の発生を防止できることから、本発明では特に好ましく選択される。
これらの硝酸塩類は、単独で使用してもよいし、２種以上を併用してもよい。
First, the nitrates constituting the fountain solution composition for lithographic printing of the present invention will be described.
The nitrates are preferably selected from the viewpoint of preventing corrosion on metals, especially aluminum, in addition to functioning as a surface-adjusting agent.
In the present invention, as the nitrates, one or more selected from the group consisting of nitrates, nitrites, and nitrite compounds can be used.
Specific examples of the nitrate include sodium nitrate, potassium nitrate, ammonium nitrate, magnesium nitrate, calcium nitrate, beryllium nitrate, aluminum nitrate, zinc nitrate, zirconium nitrate, nickel nitrate, manganese nitrate, chromium nitrate and the like.
Specific examples of the nitrite include potassium nitrite, sodium nitrite, lithium nitrite, barium nitrite, silver nitrite and the like, and specific examples of the nitrite compound include nitrite ester and the like.
Among the above, sodium nitrate, potassium nitrate, and ammonium nitrate are preferable from the viewpoint of obtaining a fountain solution composition for lithographic printing that has little influence on the printing plate and has excellent printing suitability such as surface smoothness. Among them, when ammonium nitrate is added to the dampening water composition for lithographic printing, when printing is resumed after printing is stopped, oxidation of the printing plate that is the aluminum substrate is suppressed, and dot-like stains (oxidized stains) are generated on the printed matter. This is particularly preferable in the present invention because it can prevent
These nitrates may be used alone or in combination of two or more.
次に、本発明の平版印刷用湿し水組成物を構成する防腐剤について説明する。
一般に防腐剤とは、湿し水組成物の保存中ないし使用中に、細菌、カビ及び酵母の発生・増殖を抑え、腐敗及び印刷諸適性の劣化を防止するものである。
本発明では、防腐剤として含窒素六員環化合物を使用する。含窒素六員環化合物は、少量の添加であっても防腐効果が長期に渡って得られる。また含窒素六員環化合物は、銅及び銅合金の防錆効果を有する。すなわち、アルミニウム等に対する防錆性を有する硝酸塩類と、銅錆耐性を有する防腐剤である含窒素六員環化合物を併用することで初めて、印刷上のトラブルの元となる様々な種類の錆を抑制することができ、例えば、銅錆によるスプレーノズルの詰まりや、印刷版の錆による紙面汚れが防止できる。その結果、整面剤としても機能する硝酸塩類の効果もあって、印刷諸適性に優れ、長期に渡って安定した平版印刷が実現できる湿し水組成物となる。さらに、長期間保存ないし使用しても腐敗することがない平版印刷用湿し水組成物となる。
Next, the preservative constituting the fountain solution composition for lithographic printing of the present invention will be described.
In general, a preservative is one that suppresses the generation and growth of bacteria, mold and yeast during storage or use of a fountain solution composition, and prevents spoilage and deterioration of printing suitability.
In the present invention, a nitrogen-containing 6-membered ring compound is used as a preservative. The nitrogen-containing 6-membered ring compound has a long-term antiseptic effect even if added in a small amount. Further, the nitrogen-containing 6-membered ring compound has an anticorrosive effect on copper and copper alloys. That is, it is possible to remove various types of rust that cause printing problems for the first time by using nitrates having anticorrosive properties against aluminum and the like and a nitrogen-containing six-membered ring compound that is an antiseptic having copper rust resistance. For example, it is possible to prevent clogging of the spray nozzle due to copper rust and stain of the paper surface due to rust on the printing plate. As a result, the fountain solution composition is excellent in various printing properties and can realize stable lithographic printing for a long period of time due to the effect of nitrates which also function as a surface-adjusting agent. Furthermore, it is a fountain solution composition for lithographic printing that does not decompose even after long-term storage or use.
含窒素六員環化合物としては、トリアジン系化合物、ピリチオン系化合物、ピリジン系化合物（ピリチオン系化合物を除く）、オキサチアジン系化合物などがある。そして、より好ましい態様として、経時安定性の悪化もなく、本発明の湿し水組成物の防腐効果が長期に渡って得られるという点で、トリアジン系化合物及び／またはピリチオン系化合物を使用することが好ましく、トリアジン系化合物を使用することが特に好ましい。

Examples of the nitrogen-containing six-membered ring compound include triazine compounds, pyrithione compounds, pyridine compounds (excluding pyrithione compounds), and oxathiazine compounds. And, as a more preferred embodiment, the use of a triazine-based compound and/or a pyrithione-based compound in that the antiseptic effect of the fountain solution composition of the present invention can be obtained over a long period without deterioration of stability over time Is preferable, and it is particularly preferable to use a triazine compound.
Specific examples of such triazine compounds include n-caprinoguanamine, 5-ethylhexylaminoguanamine, 2,4-bis(N,N'-dipropylamino)-6-chloro-1,3,3. 5-triazine, 2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine, 2,4-diethyl-6-octylamino-1,3,5-triazine, hexahydro-1,3 , 5-triethyl-S-triazine, and hexahydro-1,3,5-trisubstituted-S-triazine compounds such as hexahydro-1,3,5-tris(2-hydroxyethyl)-S-triazine.
Further, more specific examples of the pyrithione compound include sodium pyrithione, zinc pyrithione, copper pyrithione, and pyrithione chitosan.

The range is more preferably 0.01% by mass to 0.03% by mass. Within the above range, the antiseptic effect is sufficiently exerted, so that the dampening solution composition can be prevented from spoiling in the pipe in the dampening water apparatus and in the filter. It is also preferable in that it can be stored in dampening water for a long period of time, and deterioration of stain resistance and surface-adjusting effect due to generation of bacteria and mold can be prevented.
本発明の平版印刷用湿し水組成物は、上記の材料に加えて、硝酸塩類以外の無機酸及びその塩を用いることができる。

また塩としてはリチウム塩、ナトリウム塩、マグネシウム塩、カリウム塩、カルシウム塩、アンモニウム塩等が挙げられる。
中でも、リチウム、ナトリウム、カリウムなどのアルカリ金属塩や、アンモニウム塩は、マグネシウムやカルシウム等の２価の陽イオンに比べて不溶性の塩を形成しにくく、印刷機上のローラーにグレーズが堆積しにくくなるため、ローラーの不感脂化による転移不良やローラー剥げといったトラブルを抑制でき、印刷諸適性に優れた平版印刷用湿し水組成物が得られるため、好ましい。
In the fountain solution composition for lithographic printing of the present invention, an inorganic acid other than nitrates and salts thereof can be used in addition to the above materials.
Examples of the inorganic acid include phosphoric acid, picolinic acid, polyphosphoric acid (tripolyphosphoric acid, hexametaphosphoric acid, etc.), silicic acid, metasilicic acid, sulfurous acid, sulfuric acid, carbonic acid and bicarbonate.
Examples of the salt include lithium salt, sodium salt, magnesium salt, potassium salt, calcium salt, ammonium salt and the like.
Among them, alkali metal salts such as lithium, sodium and potassium, and ammonium salts are less likely to form insoluble salts than divalent cations such as magnesium and calcium, and glazes are less likely to be deposited on the rollers of the printing machine. Therefore, troubles such as poor transfer and roller peeling due to desensitization of the roller can be suppressed, and a fountain solution for lithographic printing having excellent printing suitability can be obtained, which is preferable.
また、無機酸及びその塩のなかでも、リン酸塩は汚れ防止剤として機能し、硝酸塩と組み合わせて使用することで、整面性に特に優れた湿し水組成物となる。そのため、本発明ではリン酸塩を含むことが好ましい。
本発明で好ましく使用できるリン酸塩の具体例として、オルトリン酸塩、ピロリン酸塩、ポリリン酸（トリポリリン酸、テトラリン酸など）塩、メタリン酸塩、ウルトラリン酸塩などのリン酸塩が挙げられる。さらに具体的には、第一リン酸〜第三リン酸のナトリウム塩、カリウム塩、またはアンモニウム塩；トリポリリン酸ナトリウムやヘキサメタリン酸ナトリウムなどの、ポリリン酸のナトリウム塩、カリウム塩、またはアンモニウム塩；酸性ピロリン酸やメタリン酸のナトリウム塩、カリウム塩、またはアンモニウム塩などが挙げられる。上記の中でも、特にヘキサメタリン酸ナトリウムが好ましく使用できる。
In addition, among inorganic acids and salts thereof, phosphate functions as a stain inhibitor, and when used in combination with nitrate, a fountain solution composition having particularly excellent surface smoothing properties is obtained. Therefore, in the present invention, it is preferable to include a phosphate.
Specific examples of the phosphate that can be preferably used in the present invention include orthophosphate, pyrophosphate, polyphosphoric acid (tripolyphosphoric acid, tetraphosphoric acid, etc.) salts, metaphosphate, and ultraphosphate. .. More specifically, sodium, potassium, or ammonium salts of primary phosphoric acid to tertiary phosphoric acid; sodium, potassium, or ammonium salts of polyphosphoric acid such as sodium tripolyphosphate or sodium hexametaphosphate; acidic; Examples thereof include sodium salts, potassium salts, ammonium salts and the like of pyrophosphoric acid and metaphosphoric acid. Among the above, sodium hexametaphosphate is particularly preferably used.
リン酸塩を含む、上記の無機酸及びその塩は、単独、もしくは複数配合することが可能である、また、目標のｐＨとするためには、例えば、上記化合物の種類や配合量を調整することで、容易に操作可能である。好適な含有量としては、平版印刷湿し水組成物中の含窒素六員環化合物に対して、１．０質量倍〜８．０質量倍量である。より好ましくは１．０質量倍量〜４．０質量倍量の範囲である。１．０質量倍量以上であると、整面効果が優れることから印刷時の汚れ耐性が良好であり、一方、８．０質量倍量以下であれば、インキのローラー転移性の劣化が発生しにくくなることから、濃度変動耐性の点において好ましい。 The above-mentioned inorganic acids and salts thereof, including phosphates, can be blended alone or in combination, and in order to attain a target pH, for example, the type and blending amount of the above-mentioned compounds are adjusted. Therefore, it can be easily operated. The preferable content is 1.0 to 8.0 times the mass of the nitrogen-containing 6-membered ring compound in the lithographic printing fountain solution composition. More preferably, it is in the range of 1.0 mass times to 4.0 mass times. When the amount is 1.0 mass times or more, the surface smoothing effect is excellent, and thus the stain resistance during printing is good. On the other hand, when the amount is 8.0 mass times or less, deterioration of the ink roller transfer property occurs. Since it is difficult to do so, it is preferable in terms of resistance to concentration fluctuation.
さらに本発明の平版印刷用湿し水組成物は、有機酸のアミン塩、及び／または、アルカノールアミンを含むことが好ましい。これらを本発明の湿し水組成物に添加することで、鉄及び銅に対する錆耐性に優れた湿し水組成物となる。

これらのアミン塩は単独でもしくは２種以上併用してもよい。

These amine salts may be used alone or in combination of two or more.
上記、有機酸のアミン塩、及び／または、アルカノールアミンの好適な含有量としては、平版印刷湿し水組成物中に対して、０．００１質量％〜０．０２質量％である。より好ましくは０．００２質量％〜０．０１５質量％の範囲である。 The preferable content of the amine salt of the organic acid and/or the alkanolamine is 0.001% by mass to 0.02% by mass with respect to the lithographic printing fountain solution composition.
