Description

【0001】
【発明の属する技術分野】
本発明は油性ボールペン又はボールペンレフィールに関し、特に、油性ボールペン又はボールペンレフィール中のインキ収容管に存在するインキ残量を外部より正確に読め取れるようにした油性ボールペン又はボールペンレフィールに関する。
【0002】
【従来技術】
油性ボールペンには先端にボールを保持するステンレス製又は、銅合金製チップを圧入してなるインキ収容管(ボールペンレフィールとも言う)に、基材となる溶剤、筆跡を残すための着色剤、滲みや粘度を調製するための樹脂、ペン先の余剰インキが紙面をよごしてしまう、いわゆるボテ泣きを防止するために、インキに弾性要素を与える曳糸性付与剤等を含有した油性インキを収納し、これをボールペンの軸筒に内蔵する簡易な構造のものが用いられている。そして、油性インキの粘度は水性ボールペンの粘度と比較して、非常に高く、滑らかであり、複写伝票などの高筆圧筆記においても優れた耐久性を有し、比較的に安価であるので広く使用されている。
【0003】
しかし、油性ボールペンに用いられている着色剤は、一般的に発色の良い染料と耐光堅牢性の良い染料とを併用している。発色の良い染料は耐光堅牢性が弱く、それだけでは公文書に用いることはできない。また、耐光堅牢性の良い染料は発色性が弱く、それだけでは油性ボールペンインキの着色剤としては用いることはできない。従って、2種以上の染料を使用することは、お互いに相溶性の問題を生じる場合があり、また、染料の骨格内に重金属であるクロムを含んでいるため、クロムが排出され環境問題が生じてしまう恐れもある。よって、いまだ満足できる性能が得られていないというのが現状である。
【0004】
そこで、この欠点を解消すべく着色剤として顔料を用いたものが提案されており、例えば特許文献1または特許文献2を挙げることができる。これらは主溶剤としてアルコール類或いはグリコール類及びグリコールモノエーテル類等が用いられている。具体的には、2−フェノキシエタノールやベンジルアルコールなどの従来の油性ボールペンインキに使用されている溶媒やジエチレングリコールやグリセリンなどの水溶性有機溶剤である。
【特許文献1】
特開2000−212496
【特許文献2】
特開2000−123102
【0005】
しかしながら、これらの溶媒を主溶媒に用いた場合には経時的に安定ではなく、ボールペンにした場合、チップ先端部分にインキが固まり書けなくなってしまう場合も考えられる。
また、これらの主溶媒をインキに用いると経時的に吸水することによりインキの物性が大きく変化し粘度低下によるインキの垂れ下がりや、チップの腐蝕などの問題が生じた。
よって、顔料を使用し、優れた油性ボールペンインキ組成物は得られていない。
【0006】
一方、近年印刷インキ業界においては、揮発性有機成分(VOC)の観点から不揮発性の植物油、特に大豆油を用いたインキが環境対応インキとして使用されてきている。一般的な大豆油インキは、アメリカ大豆油協会の承認を得てSOYシールを貼ることができるインキとして知られている。
印刷インキに大豆油を用いた例として特許文献3や特許文献4などが上げられる。しかし、これらの特許文献に記載されている大豆油を使用した環境対応インキはオフセット印刷や枚葉印刷等の印刷に適したインキであり、このまま或いは希釈しただけではボールペンインキとしては使用できないのが現状である。
【特許文献3】
特開2000−290576号
【特許文献4】
特開2001−279147号
【0007】
ところで、油性ボールペンにおいて、インキの残量を外部からの透視によって確認できるようにすることは油性ボールペンとして重要な特性の1つである。一般のインキ収容管内壁やボールペンインキ組成物においては、インキ収容管内壁とインキの境界面を作り透明又は半透明のインキ収容管内のインキ残量が確認できるようにシリコンオイルが添加されている。しかし、植物油または植物油誘導体を基油として用いた油性ボールペンインキ組成物の場合、一般のシリコンオイルではインキとインキ収容管内壁の境界面が形成されずインキ残量が確認できない問題が明らかになった。また、特許文献5では脂肪酸アマイドワックスを含有してなるインキをボールペンまたはボールペンレフィールインキのインキ収容部に収容した場合、収容部の内壁面を脂肪酸アマイドワックスと相溶しないオイルで処理する方法することが記載されている。

【発明が解決しようとする課題】
本発明の目的は、油性ボールペンにおいて、インキ収容管に存在するインキ残量を外部より正確に読め取れるようにした油性ボールペン又はボールペンレフィールを提供することであり、特に、環境にやさしい植物油または植物油誘導体を基油として用いたインキ組成物の場合でも透明又は半透明のインキ収容管中のインキ残量が視認できるボールペン又はボールペンレフィールを提供することである。

BACKGROUND OF THE INVENTION
The present invention relates to an oil-based ballpoint pen or a ballpoint pen refill, and more particularly to an oily ballpoint pen or a ballpoint pen refill that enables the remaining amount of ink present in an ink receiving tube in the oil-based ballpoint pen or the ballpoint pen refill to be accurately read from the outside.
[0002]
[Prior art]
Oil-based ballpoint pens are made of stainless steel or copper alloy tips that hold the ball at the tip, and ink storage tubes (also called ballpoint pen refills) are made into base materials, coloring agents for leaving handwriting, bleeding, In order to prevent the so-called crying, the resin for adjusting the viscosity, the surplus ink at the nib squeezes the paper surface, and contains oil-based ink containing a spinnability imparting agent that gives the ink an elastic element, The thing of the simple structure which incorporates this in the axial cylinder of a ball-point pen is used. The viscosity of oil-based inks is very high and smooth compared to that of water-based ballpoint pens, and it has excellent durability even in high writing pressure writing such as copy slips, and is relatively inexpensive so it is widely used. in use.
[0003]
However, the colorant used in oil-based ballpoint pens generally uses a dye having good color development and a dye having good light fastness. Dyes with good coloring have poor light fastness and cannot be used for official documents by themselves. In addition, dyes with good light fastness have poor color development and cannot be used as colorants for oil-based ballpoint pen inks alone. Therefore, the use of two or more dyes may cause compatibility problems with each other, and since chromium, which is a heavy metal, is contained in the skeleton of the dye, chromium is discharged, causing environmental problems. There is also a risk. Therefore, the current situation is that satisfactory performance has not yet been obtained.
[0004]
Therefore, in order to eliminate this defect, a pigment using a pigment as a colorant has been proposed. For example, Patent Document 1 or Patent Document 2 can be cited. In these, alcohols or glycols and glycol monoethers are used as main solvents. Specifically, it is a solvent used in conventional oil-based ballpoint pen inks such as 2-phenoxyethanol and benzyl alcohol, and a water-soluble organic solvent such as diethylene glycol and glycerin.
[Patent Document 1]
JP2000-212696
[Patent Document 2]
JP 2000-123102 A
[0005]
However, when these solvents are used as the main solvent, they are not stable over time, and when a ballpoint pen is used, there is a possibility that the ink is hardened and cannot be written on the tip portion of the chip.
In addition, when these main solvents are used in the ink, the physical properties of the ink are greatly changed by absorbing water over time, causing problems such as ink sag due to viscosity reduction and chip corrosion.
Therefore, an excellent oil-based ballpoint pen ink composition using a pigment has not been obtained.
[0006]
On the other hand, in recent years, in the printing ink industry, from the viewpoint of volatile organic components (VOC), inks using non-volatile vegetable oils, particularly soybean oil, have been used as environmentally friendly inks. Common soybean oil ink is known as an ink that can be applied with an SOY seal with the approval of the American Soybean Oil Association.
Examples of using soybean oil for printing ink include Patent Document 3 and Patent Document 4. However, environmentally friendly inks using soybean oil described in these patent documents are inks suitable for printing such as offset printing and sheet-fed printing, and cannot be used as ballpoint pen inks as they are or after being diluted. Currently.
[Patent Document 3]
JP 2000-290576 [Patent Document 4]
JP 2001-279147 A
By the way, in an oil-based ballpoint pen, it is one of the important characteristics as an oil-based ballpoint pen to make it possible to confirm the remaining amount of ink by external perspective. In a general ink containing tube inner wall or a ballpoint pen ink composition, silicon oil is added so as to form an interface between the ink containing tube inner wall and the ink and to check the remaining amount of ink in the transparent or translucent ink containing tube. However, in the case of oil-based ballpoint pen ink compositions using vegetable oil or vegetable oil derivatives as the base oil, the problem that the remaining amount of ink cannot be confirmed because the interface between the ink and the inner wall of the ink containing tube is not formed with ordinary silicone oil. . Moreover, in patent document 5, when the ink containing a fatty acid amide wax is accommodated in the ink accommodating part of a ball-point pen or a ball-point refill ink, the inner wall surface of a accommodating part is processed with the oil which is not compatible with fatty acid amide wax. Is described.

Japanese Patent Laid-Open No. 11-20371
[Problems to be solved by the invention]
An object of the present invention is to provide an oil-based ballpoint pen or a ballpoint pen refill that can accurately read the remaining amount of ink present in the ink storage tube from the outside in an oil-based ballpoint pen, and in particular, an environmentally friendly vegetable oil or vegetable oil derivative. It is to provide a ballpoint pen or a ballpoint pen refill in which the remaining amount of ink in a transparent or translucent ink containing tube can be visually recognized even in the case of an ink composition using as a base oil.
[0009]
[Means for solving the problems]
The gist of the invention of the present application is that a ballpoint pen or ballpoint pen refill is characterized in that a fluorine-modified silicone oil or a silicone-modified fluorine resin is interposed on the contact surface between the ink containing tube inner wall of the ballpoint pen or ballpoint pen refill and the oil-based ballpoint pen ink composition. It is.
That is, in the present invention, fluorine-modified silicone oil or silicone-modified fluororesin is present on the contact surface between the inner wall of the ink-holding tube of the ballpoint pen or ballpoint pen refill and the oil-based ballpoint pen ink composition. Alternatively, it may be present on the inner wall of the ink storage tube of the ballpoint pen refill by means such as coating, or the ink storage tube itself may be molded with a fluorine-modified silicone oil or a resin composition containing a silicone-modified fluorine resin, or an ink composition It may be present in the object. In particular, when the base oil of this ink composition is soybean oil of vegetable oil, it is preferable because a boundary surface showing the remaining amount of ink can be formed regardless of the environment-friendly ink.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in detail below.
The solvent used in the oil-based ballpoint pen ink composition in the present invention may be any solvent as long as it is used in ordinary oil-based ink compositions, but is preferably a vegetable oil or a vegetable oil derivative.
Specifically, vegetable oils include dry oils such as cucumber nut oil, safflower oil, soybean oil, evening primrose oil, sunflower oil, grape seed oil, rosehip oil, almond oil, sesame oil, corn oil, rapeseed oil, cottonseed oil, etc. Semi-drying oils and non-drying oils such as avocado oil, olive oil, sasanqua oil, castor oil, camellia oil, peanut oil and the like can be mentioned. These solvents may be used alone or in combination of two or more. Soybean oil is particularly preferable from the viewpoint of VOC.
Examples of vegetable oil derivatives include unsaturated fatty acids such as oleic acid, linoleic acid and undecylenic acid, alcohols such as lauryl alcohol and behenyl alcohol, and esters such as ethyl oleate and ethyl linoleate. These solvents may be used alone or in combination of two or more.
Two or more vegetable oils and vegetable oil derivatives may be used in combination.
[0011]
A wide range of pigments can be used for the oil-based ballpoint pen ink composition in the present invention. As examples of suitable pigments, general colorant pigments such as phthalocyanine blue, benzine yellow, and carbon black can be used. In addition, a dispersed pigment base in which a pigment is dispersed in a vegetable oil or a vegetable oil derivative can also be used.
[0012]
As the resin used in the oil-based ballpoint pen ink composition in the present invention, a wide range of resins can be used as long as they are soluble and compatible with a solvent. These are important for preventing ink bleeding and adjusting the viscosity.
Specifically, Superester A-100 (manufactured by Arakawa Chemical Co., Ltd.), Harrier Star DS-90 (manufactured by Harima Chemical Co., Ltd.), Harrier Star NL (manufactured by Harima Chemical Co., Ltd.), Harrier Modified rosin ester resins such as Star P (manufactured by Harima Kasei Co., Ltd.), alkylated pyrrolidones such as AGRIMER AL10LC, ANTARON V-216, ANTARON V-220 (both manufactured by ASP Japan Co., Ltd.), LIR410, Examples thereof include liquid rubber having a molecular weight of about 10,000 or less such as UC-1 (both Kuraray Co., Ltd.), and other polymerized vegetable oils such as oligomeric esters and blown castor oil.
[0013]
Specific examples of the fluorine-modified silicone oil or silicone-modified fluororesin used in the present invention are added to the oil-based ballpoint pen ink composition, or kneaded into the resin for forming the inner wall of the ink container or forming the ink container. Is mentioned.
That is, FL100, X-22-819, X-22-820, X-22-821 (both manufactured by Shin-Etsu Silicone Co., Ltd.), FQF501 (manufactured by Toshiba Silicone Co., Ltd.), FS1265 (Toray Industries, Inc.) Fluorine-modified silicone oil such as Dow Corning Silicone Co., Ltd., and silicone-modified fluorine resin such as ZX-010B (Fuji Kasei Kogyo Co., Ltd.).
In addition, the oil-based ballpoint pen ink composition may include antiseptics such as antiseptics, benzotriazoles and various chelating agents, antifoaming agents composed of anionic or nonionic surfactants, and spinnability improvers. Various additives such as these can be added as appropriate.
[0014]
The method for producing the ink composition used in the present invention is as follows. When the pigment is used as the colorant or when the pigment and the dye are used in combination, the ink component is subjected to a dispersion treatment using a known dispersing machine such as a roll mill, a ball mill, a bead mill, or a sand mill. In this way, an ink intermediate can be obtained. This step is not necessary when using a dispersed pigment base in which a pigment is dispersed. Thereafter, the ink can be obtained by adding the additive and the resin in this order and stirring and mixing the ink components to dissolve them. If necessary, heating is performed at the time of mixing or a mixture is obtained, and then coarse particles are removed by filtration or centrifugal treatment to finally obtain an ink.
[0015]
Next, it is not necessary to use a special method as a method of applying and treating the inner wall of the ink containing portion, for example, using a paint in which the above-described fluorine-modified silicone oil or silicone-modified fluorine-based resin is dissolved or suspended. What is necessary is just to apply | coat to the inner wall surface of an oil-based ink accommodating part. In addition, when the ink container is present in the ink container itself, the ink container may be formed by adding fluorine-modified silicone oil or silicone-modified fluororesin to the synthetic resin composition forming the ink container.
[0016]
