Description
本発明は、連続気泡を有する多孔質印字体を用いる浸透印に使用され、ダイレクトメール等の印刷物に印刷されている住所や名前等の印刷文字を判読不可能にするための浸透印用油性インキに関する。 The present invention is an oil-based ink for penetrating seals that is used for penetrating stamps using a porous printed body having open cells and for making printed characters such as addresses and names printed on printed matter such as direct mail unreadable. About.
ダイレクトメールや各種引き落としの明細書等には、住所や名前やカード番号など他人に知られたくないプライバシーに関する情報が印刷されている。
このようなダイレクトメール等を廃棄する際は、シュレッダー等で裁断する、或いは、プライバシー情報箇所を手で不規則に破く必要があった。
そこで、隠したいプライバシー情報箇所を容易かつ確実に消去隠蔽できる手段として、本出願人はリモネンを配合した油性インキを提案している。
Information related to privacy that you do not want others to know, such as your address, name, and card number, is printed on your direct mail and various debit details.
When discarding such direct mail or the like, it was necessary to cut with a shredder or the like, or to manually break the privacy information portion.
Therefore, the present applicant has proposed an oil-based ink containing limonene as means for easily and surely erasing and concealing the privacy information portion desired to be hidden.
しかし、特開２００５−２３２３９２号発明の油性インキは、リモネンの柑橘系のきつい臭いがあり、人により好き嫌いがあった。また、溶剤としてグリコール系溶剤を用いているので、溶剤の揮発によってインキ粘度が変化し、浸透印の多孔質印字体中で目詰まりすることがあった。 However, the oil-based ink of the invention of Japanese Patent Application Laid-Open No. 2005-232392 has a limonene citrus-based odor and was liking and disliked by people. Further, since a glycol-based solvent is used as the solvent, the ink viscosity changes due to the volatilization of the solvent, and clogging may occur in the porous printed body of the penetrating mark.
リシノール酸メチルと、着色剤と、前記リシノール酸メチルに可溶な樹脂と、酸化防止剤を配合してなる浸透印用油性インキを内蔵した浸透印を用いてプライバシー情報箇所に捺印し、前記リシノール酸メチルが印刷トナー文字を固定している樹脂を溶解し、また、前記着色剤が剥離した印刷文字の着色剤と混合して、前記プライバシー情報箇所を判別不能にする方法。
前記浸透印用油性インキに、粘度調整剤としてメタノール、エタノール、ｎ−プロパノール、ｉ−プロパノール、ｎ−ブタノール、ｉ−ブタノールから選ばれる単独または２種以上の低級アルコールを更に配合した浸透印用油性インキを用いた請求項１に記載のプライバシー情報箇所を判別不能にする方法。
Using a penetrating seal containing a penetrating oil-based ink containing a mixture of methyl ricinoleate, a colorant, a resin soluble in the methyl ricinoleate, and an antioxidant, the privacy information is printed on the privacy information section. A method in which methyl acid dissolves a resin fixing printed toner characters and mixes with a colorant of a printed character from which the colorant has been peeled to make the privacy information portion indistinguishable.
Osmotic oil for osmotic printing, further comprising a single or two or more lower alcohols selected from methanol, ethanol, n-propanol, i-propanol, n-butanol and i-butanol as viscosity modifiers. The method of making the privacy information location of Claim 1 using ink indistinguishable.
本発明インキを内蔵した浸透印を用いてダイレクトメールや各種引き落としの明細書等のプライバシー情報箇所に捺印すると、リシノール酸メチルが印刷トナー文字を固定している樹脂を溶解し、印刷文字の着色剤が紙面から剥離して、プライバシー情報箇所が確実に消去できた。
また、本発明インキの着色剤が、剥離した印刷文字の着色剤と混合するので、プライバシー情報箇所は判別不能となり、確実にプライバシーを守ることができた。
When printing on privacy information such as direct mail and various withdrawal details using the penetrating seal with ink of the present invention, methyl ricinoleate dissolves the resin fixing the printed toner character, and the colorant for the printed character Peeled off from the page, and the privacy information part could be erased securely.
In addition, since the colorant of the ink of the present invention is mixed with the colorant of the peeled printed characters, the privacy information location is indistinguishable, and privacy can be reliably protected.
以下、本発明を詳細に説明する。
本発明に用いる主溶剤としては、リシノール酸メチルを用いる。リシノール酸エチル、リシノール酸ブチル、ステアリン酸メチルなど、他の高級脂肪酸と低級アルコールとのエステルは、印刷トナー文字を固定している樹脂を溶解することができないので用いることができない。本発明インキに対するリシノール酸メチルの配合比はインキ組成中５０〜９９重量％、好ましくは７０〜９０重量％である。
また、使用状況や環境等に適合させるため、粘度調整剤としてメタノール、エタノール、ｎ−プロパノール、ｉ−プロパノール、ｎ−ブタノール、ｉ−ブタノールなどの低級アルコールを補助溶剤として更に配合することができる。低級アルコールを本発明インキに使用する際は、得られるインキが適当な粘度となるように上記の溶剤を単独または２種以上用いることができ、その配合比はインキ組成中１〜３０重量％程度であり、好ましくは５〜２０重量％である。
Hereinafter, the present invention will be described in detail.
As the main solvent used in the present invention, methyl ricinoleate is used. Esters of other higher fatty acids and lower alcohols such as ethyl ricinoleate, butyl ricinoleate, and methyl stearate cannot be used because they cannot dissolve the resin fixing the printed toner characters. The blending ratio of methyl ricinoleate to the ink of the present invention is 50 to 99% by weight, preferably 70 to 90% by weight in the ink composition.
Moreover, in order to adapt to a use condition, an environment, etc., lower alcohols, such as methanol, ethanol, n-propanol, i-propanol, n-butanol, i-butanol, can be further mix | blended as a cosolvent as a viscosity modifier. When a lower alcohol is used in the ink of the present invention, the above solvents can be used alone or in combination of two or more so that the resulting ink has an appropriate viscosity, and the blending ratio is about 1 to 30% by weight in the ink composition. And preferably 5 to 20% by weight.
着色剤としては、特に制限されることなく従来公知の有機顔料及び無機顔料、従来公知の油溶性染料を特に制限されることなく使用することができる。
顔料としては、例えば、縮合アゾ系、フタロシアニン系、キナクリドン系、アンスラキノン系、ジオキサジン系、インジゴ・チオインジゴ系、ベリノン・ベリレン系、イソインドレノン系、アゾメチレンアゾ系、ジケトピロロピロール系などの有機顔料や、カーボンブラック、マイカ、チタン白、パール顔料、酸化鉄・アルミニウム粉・真鍮等金属顔料などの無機顔料を用いることができる。これらの顔料は通常、ニトロセルロース、エチルセルロース、塩化ビニル／酢酸ビニルコポリマー、ロジンエステルなどの公知の樹脂などに練り込んで加工顔料としておくと、溶剤と混合する際に容易に分散するので便利である。また、既に分散剤中に顔料を練り込んである市販の加工顔料として、ＭＩＣＲＯＬＩＴＨ Ｂｌａｃｋ Ｃ−Ａ、ＭＩＣＲＯＬＩＴＨ Ｓｃａｒｌｅｔ Ｒ−Ａ、ＭＩＣＲＯＬＩＴＨ Ｙｅｌｌｏｗ ２Ｒ−Ａ、ＭＩＣＲＯＬＩＴＨ Ｒｅｄ ４Ｃ−Ｋ、ＭＩＣＲＯＬＩＴＨ Ｂｌｕｅ ４Ｇ−Ｔ（以上、チバ・スペシャリティ・ケミカルズ株式会社製）などを用いてもよい。これらの顔料は色合いを勘案しながら単独又は混合して使用でき、インキ全量に対し１〜３０重量％の顔料分が使用できる。
染料としては、モノアゾ系、ジスアゾ系、金属錯塩型モノアゾ系、アントラキノン系、フタロシアニン系、トリアリルメタン系などを例示することができる。これらの油溶性染料は色合いを勘案しながら単独又は混合して使用でき、インキ全量に対し１〜３０重量％を使用することができる。

本発明を得るには、上記物質を適量選択して、撹拌機にて常温以上１００℃以下で約２時間混合分散して製造する。本発明では、粘度を自由に設定することができるが、特に、１００〜１０００ｍＰａ・ｓ（２５℃）に調整することが好ましい。この範囲以上では印影が乾燥するまでに時間がかかりすぎ、これ以下ではにじみを防止することが困難だからである。本発明の最も好ましい粘度の範囲は、２００〜２０００ｍＰａ・ｓ（２５℃）である。
以下、本発明を実施例を用いて説明するが、もちろん以下の実施例に限定されるものではない。
In order to obtain the present invention, an appropriate amount of the above-mentioned substances are selected and mixed and dispersed for about 2 hours at room temperature to 100 ° C. with a stirrer. In this invention, although a viscosity can be set freely, it is preferable to adjust to 100-1000 mPa * s (25 degreeC) especially. This is because it takes too much time for the seal impression to dry above this range, and it is difficult to prevent bleeding below this range. The most preferable viscosity range of the present invention is 200 to 2000 mPa · s (25 ° C.).
