Description

本発明は、書籍、チラシ、カタログ等の印刷物に使用されるオフセット印刷インキ(以下、「インキ」と略す。)に関するものであり、特に、添加剤によって乳化適性を微調整されたインキに関するものであり、更に詳しくは水有り印刷において発生する湿し水に係る印刷トラブルを低減して印刷紙面の品質を改善し、印刷の作業効率を向上させ、印刷作業環境を向上させる為のインキに関するものである。   The present invention relates to an offset printing ink (hereinafter abbreviated as “ink”) used for printed matter such as books, leaflets, and catalogs, and particularly relates to an ink whose emulsification ability is finely adjusted by an additive. Yes, more specifically, it relates to ink for reducing printing trouble related to dampening water generated in printing with water, improving the quality of printing paper, improving printing work efficiency, and improving the printing work environment. is there.

オフセット水有り印刷では、インキがインキ壷から複数のローラーを経由して版面に供給され、湿し水が水舟から複数のローラーを経由して版面に供給される。版面の画線部は親油性であるのでインキが受理され、版面の非画線部は親水性であるので湿し水で被覆される事により、紙面に画像が再現される。供給されるインキ量と供給される湿し水量が不均衡な場合、印刷トラブルが発生する事がある。例を挙げると、版面の非画線部において湿し水が不足すると非画線残りと一般的に称するパイリング現象が発生する。また、湿し水が過剰に供給されると、水棒絡み、水目、濃度変動、フライング等の印刷トラブルが誘発される。これらの印刷トラブルを防止し、優れた印刷紙面を再現する為には、印刷機上でのインキと湿し水の乳化状態を制御し、水幅(印刷機あるいは紙面に対して湿し水に起因するトラブルが発生しない水上がり量の幅)を拡大する印刷インキの処方設計が必要である。近年、オフセット印刷機の性能向上に伴う高速印刷化が益々進行すると共に、印刷用紙の古紙利用比率が上昇しているので、インキと湿し水の需給バランスが変化し、最適かつ安定した乳化状態を保持する事が困難になっている。   In printing with offset water, ink is supplied from the ink fountain to the plate surface via a plurality of rollers, and dampening water is supplied from the water boat to the plate surface via a plurality of rollers. Since the image area on the printing plate is oleophilic, ink is accepted, and since the non-image area on the printing plate is hydrophilic, the image is reproduced on the paper surface by coating with dampening water. If the amount of ink supplied and the amount of dampening water supplied are imbalanced, printing trouble may occur. For example, if dampening water is insufficient in the non-image area of the printing plate, a piling phenomenon generally referred to as non-image area remains. Further, when dampening water is supplied excessively, printing troubles such as water rod entanglement, water eyes, density fluctuation, and flying are induced. In order to prevent these printing troubles and to reproduce an excellent printing paper surface, the emulsification state of the ink and the dampening water on the printing machine is controlled, and the water width (the dampening water is applied to the printing machine or the paper surface). It is necessary to design a prescription for printing ink that expands the range of the amount of rising water that does not cause trouble. In recent years, with the progress of high-speed printing accompanying the improvement in the performance of offset printing presses, the ratio of waste paper used for printing paper has increased, so the supply and demand balance of ink and fountain solution has changed, and an optimal and stable emulsification state It is difficult to hold.

従来から存在する乳化抑制剤あるいは乳化促進剤は、非天然物由来のものが多く、分子中に炭素原子を4から15個包含するジオールを用いたり(特開2000−290576)、ダイマー酸と炭素数2〜6のジオールから得られる数平均分子量700〜3000のポリエステルジオールを用いている(特開平9−143416)。の近年志向されている環境配慮の観点からは、天然物に由来する物質への代替が求められている。従来から存在する乳化抑制剤あるいは乳化促進剤は、少量の添加で効果が顕著に発現し、乳化適性の精密な制御を困難にしている。
特開2000−290576号公報 特開平9−143416号公報
Conventional emulsification inhibitors or emulsification accelerators are often derived from non-natural products, such as using diols containing 4 to 15 carbon atoms in the molecule (Japanese Patent Laid-Open No. 2000-290576), dimer acid and carbon. A polyester diol having a number average molecular weight of 700 to 3000 obtained from a diol having a number of 2 to 6 is used (Japanese Patent Laid-Open No. 9-143416). From the viewpoint of environmental consideration, which has recently been aimed at, there is a need for substitution for substances derived from natural products. Conventionally existing emulsification inhibitors or emulsification accelerators are remarkably effective when added in a small amount, making precise control of emulsification suitability difficult.
JP 2000-290576 A JP-A-9-143416

本発明は、このような従来の技術における問題点を解決する為になされたものであり、その課題とするところは、インキの乳化適性を如何に微調整し、かつ天然由来物質を使用し、乳化に係る問題を解消した良好な印刷物を得る事が出来るインキを提供する事である。   The present invention has been made to solve such problems in the prior art, and the subject is how to finely adjust the emulsification suitability of the ink and use a naturally derived substance, An object of the present invention is to provide an ink capable of obtaining a good printed matter that solves the problems associated with emulsification.

即ち本発明は、顔料5〜30重量%、バインダー樹脂20〜50重量%、植物油類1〜40重量%、溶剤1〜45重量%、長鎖ジオール0.05〜5重量%及び/または変性植物油0.1〜5重量%からなるオフセット印刷インキ組成物に関する。 That is, the present invention comprises 5 to 30% by weight pigment, 20 to 50% by weight binder resin, 1 to 40% by weight vegetable oil, 1 to 45% by weight solvent, 0.05 to 5% by weight long chain diol and / or modified vegetable oil. The present invention relates to an offset printing ink composition comprising 0.1 to 5% by weight.

また本発明は、長鎖ジオールがヒマシ油に由来する事を特徴とする上記オフセット印刷インキ組成物に関する。   The present invention also relates to the offset printing ink composition, wherein the long-chain diol is derived from castor oil.

さらに本発明は、変性植物油が、大豆油に由来するモノグリセリド及び/またはジグリセリドである事を特徴とする上記オフセット印刷インキ組成物に関する。   Furthermore, the present invention relates to the offset printing ink composition, wherein the modified vegetable oil is monoglyceride and / or diglyceride derived from soybean oil.

本発明によって、オフセット印刷インキ組成物の乳化性状を微調整する事が容易となり、湿し水に関する印刷不具合を低減する事が可能となる。   According to the present invention, it becomes easy to finely adjust the emulsification property of the offset printing ink composition, and it is possible to reduce printing defects related to dampening water.

従来使用されている乳化抑制剤は、炭素数が6〜13のジオールが通常であり、石油に由来している。本発明の乳化抑制剤は、炭素数が16〜18である長鎖の骨格を有し、ヒマシ油に由来する長鎖ジオールである。長鎖ジオールの添加量は印刷インキ組成物の全量に対して0.05から5重量%が好ましく、更に好ましくは0.1〜2重量%である。0.05重量%未満の添加量では、充分な乳化抑制効果を発揮せず、5重量%を超過する添加量では、印刷インキが湿し水を過剰に反撥し、ローラー上を転移する印刷インキ表面に表出した湿し水が、印刷インキのローラー間の円滑な転移を阻害する。   Conventionally used emulsification inhibitors are usually diols having 6 to 13 carbon atoms and are derived from petroleum. The emulsification inhibitor of the present invention is a long-chain diol having a long-chain skeleton having 16 to 18 carbon atoms and derived from castor oil. The addition amount of the long-chain diol is preferably 0.05 to 5% by weight, more preferably 0.1 to 2% by weight, based on the total amount of the printing ink composition. If the addition amount is less than 0.05% by weight, the effect of suppressing the emulsification is not sufficiently exhibited. If the addition amount exceeds 5% by weight, the printing ink is dampened with water and excessively repels water, and the printing ink is transferred on the roller. The fountain solution exposed on the surface inhibits the smooth transfer between the printing ink rollers.

従来使用されている乳化促進剤は、ポリオキシプロピレンモノブチルエーテルの如く合成物質である事が通常である。本発明の乳化促進剤は、大豆油に由来するモノグリセリド及び/またはジグリセリドである変性植物油である。変性植物油の添加量は印刷インキ組成物の全量に対して0.05から5重量%が好ましく、更に好ましくは0.1〜2重量%である。0.05重量%未満の添加量では、充分な乳化促進効果を発揮せず、5重量%を超過する添加量では、印刷インキと湿し水の界面張力が低下し、地汚れを誘発する。   Conventionally used emulsification accelerators are usually synthetic substances such as polyoxypropylene monobutyl ether. The emulsification accelerator of the present invention is a modified vegetable oil that is a monoglyceride and / or diglyceride derived from soybean oil. The amount of the modified vegetable oil added is preferably 0.05 to 5% by weight, more preferably 0.1 to 2% by weight, based on the total amount of the printing ink composition. When the addition amount is less than 0.05% by weight, sufficient emulsification promoting effect is not exhibited, and when the addition amount exceeds 5% by weight, the interfacial tension of the printing ink and the dampening water is lowered, and background staining is induced.

また、本発明において、前記長鎖ジオールと前記変性植物油を各々単独で使用しても好ましいが、併用は乳化適性を微調整する上で更に好ましい。   In the present invention, the long-chain diol and the modified vegetable oil are preferably used alone, but the combined use is more preferable for finely adjusting the emulsification ability.

本発明におけるインキは、顔料5〜30重量%、バインダー樹脂20〜50重量%、植物油類1〜40重量%、溶剤1〜45重量%、長鎖ジオール0.05〜5重量%及び/または変性植物油0.05〜5重量%からなっている。インキの種類としては、オフセット輪転印刷機用インキ、枚葉印刷機用インキが主なものであるが、これに限定されるものではない。 The ink in the present invention comprises 5 to 30% by weight of pigment, 20 to 50% by weight of binder resin, 1 to 40% by weight of vegetable oil, 1 to 45% by weight of solvent, 0.05 to 5% by weight of long chain diol and / or modified. It consists of 0.05-5% by weight of vegetable oil. The main types of ink are offset rotary printing press ink and sheet-fed printing press ink, but are not limited thereto.

Among triglycerides of glycerin and fatty acids, at least one fatty acid is a fatty acid having at least one carbon-carbon unsaturated bond, and those triglycerides. Examples include fatty acid monoesters obtained by ester reaction with saturated or unsaturated alcohols, or fatty acid monoesters obtained by direct ester reaction between fatty acids of vegetable oil and monoalcohols, and ethers.

植物油として代表的ものは、アサ実油、アマニ油、エノ油、オイチシカ油、オリーブ油、カカオ油、カポック油、カヤ油、カラシ油、キョウニン油、キリ油、ククイ油、クルミ油、ケシ油、ゴマ油、サフラワー油、ダイコン種油、大豆油、大風子油、ツバキ油、トウモロコシ油、ナタネ油、ニガー油、ヌカ油、パーム油、ヒマシ油、ヒマワリ油、ブドウ種子油、ヘントウ油、松種子油、綿実油、ヤシ油、落花生油、脱水ヒマシ油などが挙げられる。   Typical vegetable oils are: Asa seed oil, flaxseed oil, eno oil, psyllium oil, olive oil, cacao oil, kapok oil, kaya oil, mustard oil, kyounin oil, kiri oil, kukui oil, walnut oil, poppy oil, sesame oil , Safflower oil, Japanese radish seed oil, soybean oil, daikon oil, camellia oil, corn oil, rapeseed oil, niger oil, nuka oil, palm oil, castor oil, sunflower oil, grape seed oil, gentian oil, pine seed oil Cottonseed oil, palm oil, peanut oil, dehydrated castor oil, and the like.

本発明で使用される溶剤は芳香族炭化水素の含有量が1重量%以下の原油由来の溶剤(石油系溶剤)である。この石油系溶剤はアニリン点が70〜110℃、沸点が230℃以上の石油溶剤が適当である。アニリン点が70℃未満の場合には樹脂を溶解させる能力が高すぎる為インキの粘度が低くなりすぎ地汚れ耐性が充分でなくなる。またアニリン点が110℃を超える場合には樹脂の溶解性が乏しい為、インキの流動性が劣り、その結果光沢、着肉性が悪い印刷物しか得ることができず好ましくない。沸点が230℃未満の場合には印刷機上でのインキ中溶剤の放出量が多くなり、インキの流動性の劣化により、ローラー、版、ブランケットへのインキの堆積が起こり易くなる為、好ましくない。
The solvent used in the present invention is a crude oil-derived solvent (petroleum solvent) having an aromatic hydrocarbon content of 1% by weight or less. As the petroleum solvent, a petroleum solvent having an aniline point of 70 to 110 ° C. and a boiling point of 230 ° C. or more is suitable. When the aniline point is less than 70 ° C., the ability to dissolve the resin is too high, and the viscosity of the ink becomes too low, resulting in insufficient scumming resistance. On the other hand, when the aniline point exceeds 110 ° C., the resin is poorly soluble, so that the fluidity of the ink is inferior, and as a result, only a printed matter with poor gloss and inking properties can be obtained. When the boiling point is less than 230 ° C., the amount of the solvent in the ink discharged on the printing machine is increased, and the ink is liable to accumulate on the rollers, plates and blankets due to the deterioration of the fluidity of the ink. .

[実施例]次に、本発明を実施例に基づいて説明する。例中、「部」は「重量部」を「%」は「重量%」を示す。尚、本発明の主旨と適用範囲を逸脱しない限り、以下の実施例は本発明を限定するものではない。 [Examples] Next, the present invention will be described based on examples. In the examples, “part” indicates “part by weight” and “%” indicates “% by weight”. The following examples do not limit the present invention without departing from the spirit and scope of the present invention.

One part of (ALCH) was heated and stirred at 190 ° C. for 1 hour to obtain a varnish for offset printing ink.

(オフセット印刷インキ組成物の製造例)オフセット印刷インキ用のワニス70部に、紅顔料(東洋インキ製造(株)製リオノールレッド 6B 4234−P−)17部、マイクロクリスタリン系ワックスコンパウンド(森村ケミカル(株)製MC−T2コンパウンド)3部、石油系溶剤(新日本石油(株)製AFソルベント7)10部を加え、常法に従い三本ロールを用いてオフセット印刷インキ組成物を得た。 (Example of production of offset printing ink composition) 70 parts of varnish for offset printing ink, 17 parts of red pigment (Toyo Ink Mfg. Co., Ltd. Lionol Red 6B 4234-P-), microcrystalline wax compound (Morimura Chemical) 3 parts of MC-T2 Compound (manufactured by Co., Ltd.) and 10 parts of petroleum solvent (AF Solvent 7 manufactured by Nippon Oil Co., Ltd.) were added, and an offset printing ink composition was obtained using a three roll according to a conventional method.

前記オフセット印刷インキ組成物に、表1の配合割合になるよう長鎖ジオール及び/または変性大豆油を添加して混合し、実施例1〜6のオフセット印刷インキ組成物を得た。 The offset printing ink compositions of Examples 1 to 6 were obtained by adding and mixing the long-chain diol and / or modified soybean oil so as to have the blending ratio shown in Table 1 to the offset printing ink composition.

前記オフセット印刷インキ組成物を、そのまま比較例1とした。 The offset printing ink composition was used as Comparative Example 1 as it was.

前記オフセット印刷インキ組成物に、従来使用の乳化抑制剤2,4−ジエチル−1,5−ペンタンジオールを添加して混合し、比較例2を得た。 Comparative Example 2 was obtained by adding and mixing the conventionally used emulsification inhibitor 2,4-diethyl-1,5-pentanediol to the offset printing ink composition.

前記オフセット印刷インキ組成物に、従来使用の乳化促進剤ポリオキシプロピレンモノブチルエーテルを添加して混合し、比較例3を得た。 Comparative Example 3 was obtained by adding and mixing the conventionally used emulsification accelerator polyoxypropylene monobutyl ether to the offset printing ink composition.

(性能評価試験)前記実施例及び比較例のオフセット印刷インキ組成物の性能評価結果を表2に示す。オフセット印刷インキ組成物の乳化適性を評価する為に、オフセット印刷インキ組成物の最大含水率を測定した。測定方法としては、一定量のインキと一定量の精製水をハイスピードミキサーにて撹拌して混合し、インキ内部に取り込まれなかった過剰な精製水を除去した上で、乳化したインキの含水率をカール・フィッシャー水分計にて測定した。インキ性能の中で、インキ内部に湿し水を受容できる許容量(最大含水率)を微調整する事が、印刷における水幅を制御する事に繋がる。従来型乳化抑制剤を使用した比較例2あるいは従来型乳化促進剤を使用した比較例3では、少量の添加でインキの最大乳化率が顕著に変化する。実施例にて使用した乳化抑制剤あるいは乳化促進剤では、効果が緩和である為、添加量を微調整する事が容易になる。 (Performance Evaluation Test) Table 2 shows the performance evaluation results of the offset printing ink compositions of the above examples and comparative examples. In order to evaluate the emulsification suitability of the offset printing ink composition, the maximum water content of the offset printing ink composition was measured. As a measuring method, a certain amount of ink and a certain amount of purified water are mixed by stirring with a high-speed mixer, and after removing excess purified water that has not been taken into the ink, the water content of the emulsified ink Was measured with a Karl Fischer moisture meter. In the ink performance, fine adjustment of the permissible amount (maximum water content) that can receive dampening water inside the ink leads to control of the water width in printing. In Comparative Example 2 using a conventional emulsification inhibitor or Comparative Example 3 using a conventional emulsification accelerator, the maximum emulsification rate of the ink changes significantly with a small amount of addition. Since the effect of the emulsification inhibitor or emulsification accelerator used in the examples is moderate, it is easy to finely adjust the addition amount.
