Abstract

PROBLEM TO BE SOLVED: To obtain a composition which is good in dispersibility and does not clog ball-point pen tubes after a long period of time and does not get pens scratchy even at low temperatures by blending a coloring agent, a pigment derivative having a sulfo group, a dispersant ad benzyl alcohol. SOLUTION: An ink composition contains 3-60 wt.% of a coloring agent, 0.05-10 wt.% of a pigment derivative in which 1-3 sulfo groups are present in a molecule such as copper phthallocyanine, a dispersant such as alkyd resin, 5 wt.% or more of an organic solvent containing benzyl alcohol as an essential component and 20-70 wt.% of a solvent such as ethylene glycol. Moreover, fatty acids, a surfactant, a rust-proofing agent and an antioxidant are blended as needed. Pigments such as carbon black, azo lake-based, benzimidazolone- based, diallylide-based, fused azo-based, quinacridone-based, diketopyrrolopyrrole- based, isoindolinone-based, perylene-based, dioxane-based, anthraquinone-based, quinophthalone-based or phthalocyanine-based pigments are used as the coloring agent.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink composition for an oil-based ballpoint pen, and more particularly, to an ink composition having a fluidity suitable for a writing instrument having a ball at a pen tip, which causes line breaks or fading of a drawn line by writing. The present invention relates to an oil-based ink composition for a ball-point pen, which is difficult to disperse, has excellent dispersion stability, and does not cause clogging even after a long time.

2. Description of the Related Art A ball-point pen comprises a ball, a pen tip including a chip holder, an ink storage tube, a pen shaft, and the like. When writing is performed by filling the ballpoint pen with oil-based ink, the ink flowing out of the chip is transferred or penetrated into a recording medium such as paper by the rotation of the ball of the pen point, thereby creating handwriting and drawing lines. At that time, surplus ink that could not be transferred or penetrated adheres to the outer periphery of the chip holder, causing a so-called bottling phenomenon that a lump of ink drops at the beginning of writing and sometimes during writing, and it is not possible to obtain a clear drawing line Sometimes.

[0003] The oil type ink used in these conventional ballpoint pens is often an ink in which an oil-soluble dye is dissolved in alcohols and / or glycol ethers. There are also pigments using pigments, and most of them are pigments dispersed with a ketone resin or alkyd resin (Japanese Patent Application Laid-Open Nos. 56-143278 and 60-4).

[0004] However, inks using oil-soluble dyes have drawbacks such as dissolution in solvents such as alcohol, fading due to sunlight, etc., and inferior robustness of drawn lines after writing. In addition, inks using pigments
The pigment is dispersed in the dispersant resin, but due to insufficient dispersion, sedimentation of the pigment occurs, etc., making it impossible to write on long-term storage or poor solubility of the dispersant at low temperatures. There is a problem with writing, such as blurring.

It is not clear why the oil-based ink composition for ballpoint pens of the present invention has good fluidity and excellent dispersibility and does not cause clogging at the pen tip. Derivatives and dispersants have improved dissolution stability due to benzyl alcohol, and furthermore, the specific pigment derivative has the effect of strengthening the interaction between the pigment and the dispersant. As a result, the effect of dispersing and preventing sedimentation is exhibited. Therefore, excellent fluidity and dispersion stability, and,
It is presumed that the pigment does not agglomerate or settle even during long-term storage, and that clogging at the pen tip does not occur. In addition, benzyl alcohol contained in the ink composition for oil-based ballpoint pens of the present invention has very good solubility of pigments, pigment derivatives and dispersants at low temperatures, and furthermore, benzyl alcohol itself is liquid even at low temperatures. Even when stored, the dissolution stability of the pigment, the pigment derivative, the dispersant, and the additives is maintained, and therefore, the ink is stable and the fluidity is maintained.

The pigment derivative used in the oil-based ballpoint pen ink composition of the present invention is a pigment derivative having a sulfone group in the molecule, and is preferably a pigment derivative having 1 to 3 sulfone groups in the molecule. By incorporating this pigment derivative, the dispersibility of the pigment is further improved, and a stable oil-based ink composition for a ballpoint pen that does not aggregate or settle even during long-term storage can be obtained. Although the reason for this is not clear, it is considered that the blending of the pigment derivative having a sulfone group has an effect of enhancing the interaction between the dispersant and the pigment. The amount of the pigment derivative is 0.05 to 10% by weight based on the total amount of the oil-based ballpoint pen ink composition,
0.1-5% by weight is preferred. When the content is 0.05% by weight or less, the effect of dispersing the pigment cannot be fully exhibited, and when the content is 10% by weight or more, the dispersion of the pigment is hindered. Examples of the pigment derivative having a sulfone group include derivatives of copper phthalocyanine and azo pigments. Solsperse 5000, Solsperse 12000, Solsperse 22000 (Zenec

As is clear from the results in Table 1, Examples 1 to 4 according to the present invention have excellent fluidity and dispersion stability.
It has been found that this is an oil-based ballpoint pen ink composition which is excellent in long-term storage property and low-temperature storage property. On the other hand, Comparative Examples 1 to 4 are examples in which a pigment derivative having a benzyl alcohol or a sulfone group and a dispersant are not used, and have poor fluidity and dispersibility, poor long-term storage properties, and low temperature. It was found that storage was poor and the desired oil-based ink composition for a ballpoint pen could not be obtained.
