【発明の属する技術分野】
本発明は、カーボンブラックをオフセット印刷インキ中に含まれる印刷インキ用常温固体樹脂との乾式粉砕を行うことで、光沢および着色力が高く、更にインキ生産性をも向上させる印刷インキの製造方法、該製法を用いたオフセット印刷インキに関するものである。
【０００２】
【従来の技術】
通常オフセット印刷インキでは、カーボンブラックを印刷インキ用溶剤及びワニス混合物中に混合、分散することにより印刷物の光沢及び着色力が発現する。
【０００３】
上記の光沢及び着色力等のオフセット印刷インキ特性を発揮するためには、カーボンブラックが印刷インキ用溶剤及びワニス混合物中に充分に分散されていることが要求されるが、そのためには充分な分散時間が必要であり、インキ製造工程に多大な時間と労力を費やすことになる。
【０００４】
【発明が解決するための課題】
本発明の目的は、従来オフセット墨インキで使用されているカーボンブラックで得られていた以上のインキ品位を実現すると同時にインキの生産性を向上させる印刷インキの製造方法およびオフセット印刷インキを提供することにある。
【０００５】
【課題を解決するための手段】
第１の発明は、カーボンブラックに印刷インキ用常温固体樹脂を加えて乾式粉砕した後、得られた粉砕物を印刷インキ用溶剤及びワニス混合物中に混合、分散することにより得られることを特徴とする印刷インキの製造方法である。
【０００６】
第２の発明は、印刷インキ用常温固体樹脂がロジン変性フェノール樹脂、ロジン変性マレイン酸樹脂、石油樹脂、アルキッド樹脂の少なくとも１種あるいは２種以上であることを特徴とする第１発明記載の印刷インキの製造方法である。
【０００７】
第３の発明は、粉砕物を印刷インキ用溶剤及びワニス混合物中に混合、分散する際の温度が６０〜１３０℃であることを特徴とする第１または第２発明記載の印刷インキの製造方法である。
【０００８】
第４の発明は、印刷インキ用常温固体樹脂の添加量がカーボンブラックに対して１〜１００重量％であることを特徴とする第１〜第３発明何れか記載の印刷インキの製造方法である。
【０００９】
第５の発明は、乾式粉砕の温度が８０〜２００℃であることを特徴とする第１〜第４発明何れか記載の印刷インキの製造方法である。
【００１０】
第６の発明は、第１〜第５発明いずれか記載の印刷インキの製造方法を用いたことを特徴とするオフセット印刷インキである。
【００１１】
【発明の実施の形態】
以下、本発明について詳細に説明する。
【００１２】
本発明に用いるカーボンブラックは、粒状、粉体であれば特に形状を問わない。
【００１３】
本発明において、乾式粉砕時にカーボンブラックに添加する印刷インキ用常温固体樹脂としては、ロジン変性フェノール樹脂、ロジン変性マレイン酸樹脂、石油樹脂、アルキッド樹脂などオフセット印刷インキに使用される樹脂であり、常温固体の樹脂である。これらは任意に単独または２種類以上を組み合わせて使用できるが、好ましくはロジン変性フェノール樹脂である。ロジン変性フェノール樹脂は、特に限定されないが、重量平均分子量が１〜１２万のものが好ましい。
【００１４】
印刷インキ用常温固体樹脂量としては、カーボンブラックに対して１〜１００重量％の範囲が好ましい。また、乾式粉砕温度としては８０〜２００℃の範囲である。
【００１５】
カーボンブラックに対する印刷インキ用常温固体樹脂の添加量が多いと、乾式粉砕機内部で樹脂の付着、固着の生じる危険性が高くなる。これは当然のことながら樹脂の軟化点、粉砕温度にも影響されるため、これらの条件を加味しながら最適処理量を決める必要がある。粉砕時間はその装置によってまたは希望とする粉砕粒径に応じて任意に設定できる。
【００１６】
乾式粉砕方法は、ビーズ、金属ボール等の粉砕メディアの内蔵有無に関わらず、実質的に液状物質を介在させないでカーボンブラックを粉砕するものである。粉砕は、粉砕メディアを使用する場合は、粉砕メディア同士の衝撃による粉砕力や破壊力を利用して行われる。乾式粉砕機としては、乾式のアトライター、ボールミル、振動ミルなどを用いることができる。
【００１７】
また、窒素などの不活性ガスを流すことにより乾式粉砕機内部の酸素濃度をコントロールして乾式粉砕を行ってもよい。
【００１８】
また、本発明で得られるカーボンブラック組成物は特開平９−２９１２２２などの粗製銅フタロシアニン組成物とは異なり、乾式粉砕時にカーボンブラック表面が酸化される。
【００１９】
尚、表面酸化されたカーボンブラックがオフセット印刷インキに与える具体的な影響としては、印刷インキ用ワニスとの濡れ性、流動性、貯蔵時の安定性、光沢の向上などが挙げられる。
【００２０】
また、添加した印刷インキ用常温固体樹脂が酸化されることによる具体的な影響としては、オフセット印刷インキの場合、湿し水に対するインキの散りの悪化が挙げられる。これは印刷インキ用常温固体樹脂が酸化されることにより樹脂表面張力が低下するためと考えられ、オフセット印刷インキ適正として好ましくない。
【００２１】
乾式粉砕機内部の酸素濃度は、粉砕機の種類、粉砕温度などの製造条件と、粉砕するカーボンブラック、印刷インキ用常温固体樹脂などの原料により決定する。また、乾式粉砕終了時に低酸素濃度であると、粉塵爆発防止の安全性の面からも有効である。
【００２２】
本発明の印刷インキの製造方法を用いてオフセット印刷インキを製造する場合の印刷インキ用溶剤またはワニス中の溶剤としては、高沸点石油系溶剤、脂肪族炭化水素溶剤、高級アルコール系溶剤などオフセット印刷インキに適した溶剤であれば芳香族を含まない溶剤であっても単独あるいは２種類以上の組み合わせで任意に使用できる。
【００２３】
また、混合・分散時の温度、時間は、６０〜１３０℃で２０〜４８０分が望ましい。
【００２４】
また、同様にオフセット印刷インキを製造する場合の印刷インキワニス用樹脂としては、ロジン変性フェノール樹脂、ロジン変性マレイン酸樹脂、石油樹脂、アルキッド樹脂など印刷インキに適した樹脂、大豆油、桐油、アマニ油など印刷インキに適した乾性油や重合乾性油などを、その他印刷インキ用の添加剤などと共に任意に単独または２種類以上を組み合わせて使用できる。

[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail.
[0012]
The carbon black used in the present invention is not particularly limited as long as it is granular or powder.
[0013]
In the present invention, the room temperature solid resin for printing ink added to carbon black at the time of dry grinding is a resin used for offset printing inks such as rosin modified phenolic resin, rosin modified maleic resin, petroleum resin, alkyd resin, It is a solid resin. These can be used alone or in combination of two or more, but rosin-modified phenolic resins are preferred. The rosin-modified phenol resin is not particularly limited, but preferably has a weight average molecular weight of 1 to 120,000.
[0014]
The amount of room temperature solid resin for printing ink is preferably in the range of 1 to 100% by weight with respect to carbon black. The dry pulverization temperature is in the range of 80 to 200 ° C.
[0015]
If the amount of the room temperature solid resin for printing ink added to the carbon black is large, the risk of resin adhesion and sticking inside the dry grinder increases. As a matter of course, this is also affected by the softening point and pulverization temperature of the resin, so that it is necessary to determine the optimum throughput while taking these conditions into consideration. The pulverization time can be arbitrarily set depending on the apparatus or the desired pulverized particle size.
[0016]
In the dry pulverization method, carbon black is pulverized substantially without a liquid substance interposed, regardless of whether or not a pulverization medium such as beads or metal balls is incorporated. When the pulverization media are used, the pulverization is performed using the pulverization force or the destructive force caused by the impact between the pulverization media. As the dry pulverizer, a dry attritor, a ball mill, a vibration mill, or the like can be used.
[0017]
Further, dry pulverization may be performed by controlling the oxygen concentration inside the dry pulverizer by flowing an inert gas such as nitrogen.
[0018]
In addition, the carbon black composition obtained in the present invention is oxidized on the surface of carbon black during dry pulverization, unlike a crude copper phthalocyanine composition such as JP-A-9-291222.
[0019]
Specific effects of the surface-oxidized carbon black on the offset printing ink include wettability with the printing ink varnish, fluidity, storage stability, and gloss improvement.
[0020]
Moreover, as a specific influence by oxidizing the normal temperature solid resin for printing ink added, in the case of offset printing ink, the deterioration of the scattering of the ink with respect to dampening water is mentioned. This is considered to be because the surface tension of the resin is lowered due to the oxidation of the room temperature solid resin for printing ink, which is not preferable as appropriate for offset printing ink.
[0021]
The oxygen concentration inside the dry pulverizer is determined by the production conditions such as the type of pulverizer and pulverization temperature, and the raw materials such as carbon black to be pulverized and room temperature solid resin for printing ink. In addition, if the oxygen concentration is low at the end of dry pulverization, it is also effective from the viewpoint of safety in preventing dust explosion.
[0022]
As a solvent for printing ink or a solvent in varnish when producing offset printing ink using the method for producing printing ink of the present invention, offset printing such as high boiling point petroleum solvent, aliphatic hydrocarbon solvent, higher alcohol solvent, etc. Solvents that do not contain aromatics can be used alone or in combination of two or more, as long as they are suitable for ink.
[0023]
The mixing and dispersing temperature and time are preferably 60 to 130 ° C. and 20 to 480 minutes.
[0024]
Similarly, as a resin for printing ink varnish when producing offset printing ink, resins suitable for printing ink such as rosin-modified phenol resin, rosin-modified maleic resin, petroleum resin, alkyd resin, soybean oil, tung oil, linseed oil A drying oil or a polymerization drying oil suitable for a printing ink can be used alone or in combination of two or more kinds together with other additives for printing ink.
[0025]
