Description
【発明の詳細な説明】
(発明の技術分野)
本発明は、ジエツト印刷用インク組成物に係
り、さらに詳しくいえば、紙、金属、プラスチツ
ク、ガラス、ゴム等に有効に用いられる耐候性の
すぐれたジエツト印刷用インク組成物に関するも
のである。
(先行技術)
ジエツト印刷方式において、貯蔵槽内のジエツ
ト印刷用インクは、圧縮空気又はポンプなどによ
り加圧され、フイルター及び圧力調節器の連結さ
れたパイプを通り、そして直径20〜300μmのオリ
フイスを有する1個又は数個のインク噴射装置に
至り、該装置を通過する際に、磁気的又は電気的
に作動する振動子によつて微粒子となり、その微
粒子の連続的な流れとなる。次に該微粒子は被記
録体に向う間に、電気的文字発生器からビデオ信
号あるいは静電気的偏向系によつて制御され、移
動している被記録体上に文字等を形成する。
上記の方法において、記録の一様化を保持する
ためには、インクを一定形状の微粒子とし、かつ
該微粒子が前記制御系の作用に鋭敏に感応しなけ
ればならない。そのためには、インクの物性とし
て粘度、比重、比抵抗、表面張力などの値が微妙
な影響を及ぼすから、これらの値には厳しい条件
が課せられている。
また、往年のジエツト印刷の対象被記録体はほ
とんどが紙であつたから、使用されるインクは、
溶剤が水系であつた。近来は金属、プラスチツク
などの工業製品へのマーキングとして有機溶剤ベ
ースのものが開発され始めた(特開昭52−41007
号公報、特開昭52−64302号公報、特開昭52−
96106号公報など参照)。
インクジエツト記録方式に適応して広汎な対象
物体上に迅速な記録をなし得るためのインクに対
する条件は、インク液独立粒子形成性に影響する
ものとして、粘度が5cP以下、比重が1.0±0.2該
粒子の信号応答性に関係するものとして電導度が
0.5×10-3S/cm以上、記録のにじみ防止に必要な
ものとして表面張力が20〜60dyn/cmなどの物性
値を有することが望ましい。そしてさらに、優れ
た接着性、乾燥性ならびに耐水性を具備すること
が求められる。何故ならば、記録乾燥後、製品相
互間あるいは水その他の物体との接触、摩擦等に
よつて、該記録が乱れ、汚染し、あるいは抹消さ
れるようであつてはならないからである。また該
インクから着色剤やビヒクルの不揮発性成分など
が晶出すると、インク流路内にあるオリフイス部
などで円滑な流れを阻害するのでこうしたものが
析出してはならない。
既存のインクにおいても上記のような点に考慮
が払われたとはいえ、インクの着色に水溶性又
は、油溶性染料が用いられているので、色材に限
りがあり、耐候性の点において満足されていな
い。
(発明の目的)

【表】Detailed Description of the Invention (Technical Field of the Invention) The present invention relates to an ink composition for jet printing, and more specifically, an ink composition with excellent weather resistance that can be effectively used for paper, metal, plastic, glass, rubber, etc. The present invention relates to an ink composition for jet printing. (Prior Art) In the jet printing method, jet printing ink in a storage tank is pressurized by compressed air or a pump, passes through a pipe connected to a filter and a pressure regulator, and passes through an orifice with a diameter of 20 to 300 μm. As it passes through the ink ejection device, it is turned into fine particles by a magnetically or electrically actuated vibrator, resulting in a continuous flow of the fine particles. Next, while the particles are moving towards the recording medium, they are controlled by a video signal from an electric character generator or by an electrostatic deflection system to form characters or the like on the moving recording medium. In the above method, in order to maintain uniform recording, the ink must be made into fine particles of a certain shape, and the fine particles must be sensitive to the action of the control system. To this end, strict conditions are imposed on the physical properties of the ink, such as viscosity, specific gravity, specific resistance, and surface tension, since these values have subtle effects. In addition, since most of the recording media used in jet printing in the past were paper, the ink used was
The solvent was water-based. Recently, organic solvent-based markings have begun to be developed for industrial products such as metals and plastics (Japanese Patent Laid-Open No. 52-41007).
Publication No. 1986-64302, Japanese Patent Application Laid-Open No. 1982-64302
(See Publication No. 96106, etc.) In order to be able to quickly record on a wide range of target objects by adapting to the inkjet recording method, the conditions for the ink that affect the ability to form independent particles of the ink liquid include a viscosity of 5 cP or less and a specific gravity of 1.0±0.2 particles. Conductivity is related to the signal response of
It is desirable that the material has a physical property value of 0.5×10 −3 S/cm or more, and a surface tension of 20 to 60 dyn/cm, which is necessary for preventing bleeding of records. Furthermore, it is required to have excellent adhesion, drying properties, and water resistance. This is because, after the record has dried, the record must not be disturbed, contaminated, or erased by contact between products or with water or other objects, friction, or the like. Furthermore, if the colorant or non-volatile components of the vehicle crystallize from the ink, they will interfere with smooth flow at orifices in the ink flow path, so these should not be precipitated. Although consideration has been given to the above points in existing inks, since water-soluble or oil-soluble dyes are used for coloring the inks, there is a limit to the number of coloring materials available, and the weather resistance is not satisfactory. It has not been. (Objective of the Invention) An object of the present invention is to provide an ink that satisfies the above-mentioned required properties, can be used regardless of the material of the recording medium, and has excellent weather resistance. It is something. (Structure of the Invention) The present invention is characterized in that in an ink containing (a) a solvent, (b) a conductivity imparting agent, (c) a surfactant, and (d) a colorant as essential components, the colorant is A jet printing ink composition that is a polymer-bound dye. The constituent components of the ink of the present invention will be explained in more detail below. (Solvent) First, as a solvent, water, alcohol, ketone, ester, ether, aromatic hydrocarbon solvent, aliphatic hydrocarbon solvent, which dissolve each component in the ink described below, may be used alone or in combination. used. Examples of alcohol solvents include methanol, ethanol, isopropyl alcohol, n-propyl alcohol, n-butyl alcohol, sec-butyl alcohol, tert-butyl alcohol, n-amyl alcohol, isoamyl alcohol, etc.
Examples of ketone solvents include acetone, methyl ethyl ketone, 2-pentanone, 3-pentanone, methyl isobutyl ketone, 2-hexanone, 2-heptanone, 4-heptanone, diisobutyl ketone,
Cyclohexanone, etc., and ester solvents such as ethyl acetate, butyl acetate,
Acetic acid n-propyl ester, acetic acid isopropyl ester, acetic acid isobutyl ester, etc. are used as ether solvents such as dioxane, tetrahydrofuran, ethylene glycol diethyl ether, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, ethylene glycol monobutyl ether, etc. Isopropyl ether, etc., aromatic hydrocarbon solvents such as toluene, xylene, aliphatic hydrocarbon solvents such as n-hexane, 2
-Methylpentane, n-heptane, n-octane, etc. can be mentioned. (Conductivity imparting agent) The conductivity imparting agent is an ionizable salt for imparting conductivity to the ink, such as ammonium, alkali metal and alkaline earth metal halides, nitrates, nitrites, and sulfates. , acetate, thiocyanate, propionate, benzoate, per 100 parts by weight of said solvent.
By adding 0.2 to 4 parts by weight, preferably 0.5 to 2 parts by weight, the required level of conductivity is 0.5×10 -3 S/
It is possible to achieve values of cm or more. (Surfactant) A surfactant can be added as a surface tension adjusting agent for the ink. When a mixture of solvents with different evaporation rates is used, the effect of adding a surfactant is to form a thin film on the ink surface, suppressing the evaporation of the solvent, preventing the occurrence of convection due to evaporation, and achieving uniform recording. It also works. The surfactant is used in an amount of 0.005 to 2 parts by weight, preferably 0.01 to 2 parts by weight, per 100 parts by weight of the solvent.
The addition of 1 part by weight shows the effect that the purpose can be fully achieved. If the amount added is smaller than the above, there will be no effect on the surface tension, and if it is used in a large amount, the drying properties of the ink will be extremely impaired. Usable surfactants include silicone surfactants, fluorine surfactants, reaction products of ethylene glycol and propylene glycol, ester or ether types of polyethylene glycol, alkylphenol types, sorbitan ester types, polyoxy Examples include nonionic surfactants such as ethylene sorbitan ester type, titanium surfactants such as polyhydroxytitanium stearate (Orgatics TPHS manufactured by Matsumoto Pharmaceutical Co., Ltd.), and acetylene surfactants. The ink composition to which a surfactant is added forms a fine dot-shaped film on the printing material. (Polymer-Bound Dye) The colorant that can be used in the present invention is a polymer-bonded dye, unlike conventional water-soluble or oil-soluble dyes. An example is polymer-bound copper phthalocyanine. This can be obtained in a nearly amorphous state by chemically bonding a long molecular chain of a polymer to copper phthalocyanine. Acrylic polymers are useful and well known as long molecular chain polymers, and Seikagen Resin manufactured by Dainichiseika Kagyo Co., Ltd. is commercially available as a polymer-bonded dye. Since the polymer-bound dye itself contains a polymer, it can also serve as a binder.
Therefore, in the ink of the present invention, there is no need to add a separate binder. Other dyes can also be added for complementary colors. Regarding polymer-bonded dyes, an explanation ("Polymer-bonded dyes" by Shojiro Horiguchi) was published on pages 316 to 321 of Volume 20, No. 4 (1977) of the magazine "Chemistry and Industry". There is. (Binder) As described above, the ink of the present invention can be constructed without adding a separate binder, but a binder can also be added if desired. The binder may be any binder as long as it is soluble in the solvent, and acts as a film-forming component of the ink. Suitable examples include low molecular weight polystyrene,
Modified xylene resin, modified mesitylene resin, alkylphenol resin, rosin resin, modified rosin resin, cashew resin, modified cashew resin, polyvinylphenol resin, terpene resin, phenolic resin, epoxy resin, polyester resin, vinyl acetate resin, polyvinyl butyral Examples include resin, polyvinyl alcohol resin, modified acrylic resin, shellac resin, glyptal resin, ester gum, and modified cellulose. The appropriate molecular weight of these is several thousand to several tens of thousands. The desired dot formation, adhesion, and drying properties can be obtained by appropriately selecting the polarity of the surface of the recording medium and the resin and surfactant used as the ink vehicle. It is necessary to carefully consider the compatibility between the ink and the ink and select an appropriate composition. The amount of binder added depends on the molecular weight, but is about 1 to 8% by weight, preferably about 2 to 6% by weight, based on the mixed solution.
Weight%. (Effect of the invention) The ink composition for jet printing according to the invention has the following properties:
Since it has the following effects, it is extremely useful industrially. (1) Can be used as ink for printing on paper, metal, plastic, glass, rubber, etc. (2) Compared to conventional jet printing inks,
Since the ink according to the present invention has much better weather resistance, it is an extremely suitable ink for printing on articles that will be used outdoors for a long period of time. (Embodiments) The following examples are intended to illustrate embodiments of the present invention and to make the present invention easier to understand, and are not intended to limit the present invention in any way.

The jet printing ink compositions of 5) and 1 Comparative Example (Experiment No. 6) were prepared and passed through a filter with a pore size of 2 μm to examine their properties. Each ink was tested for printing on a metal plate using a P-610 Hitachi IJ printer (manufactured by Hitachi, Ltd.). All inks were ejected as independent fine particles, and clear records were obtained. These test pieces were continuously subjected to weather resistance tests outdoors for 6 months.
There was almost no difference in color density, and the results were very good. On the other hand, in Experiment 6, color fading was observed after about 50 hours, indicating that the ink had poorer weather resistance than the ink of the present invention. 【table】
