Definitions
- the present invention relates to an ink composition for an oil-based ballpoint pen, a method for producing the same, and a ballet finole.
- ballpoint pens are desired to have good writing quality, excellent handwriting dryness, no bleeding or lining of the handwriting, high handwriting clarity, chemical stability, and little change over time.
- ⁇ Is set in the range of 10, 00 to 30, 00 OmPas at an ink viscosity of 20 ° C. This is higher than the ink viscosity of an ink for an aqueous ballpoint pen. If the ink viscosity of an oil-based ballpoint pen is high, the ball rotation resistance during writing naturally increases, and the writing quality is extremely heavy and poor. On the other hand, if the ink viscosity is reduced too much, ink leakage occurs and handwriting dryness deteriorates. For this reason, the ink viscosity is set in the above range.
- the ink for oil-based ballpoint pens has a higher ink viscosity than the ink for water-based ballpoint pens, and discharges less ink from the end of the brush. This is because the ink ejection mechanism of an oil-based pole pen is pen-rotated and the ink attached to the ball is transferred to the writing surface to produce handwriting, whereas the water-based ball-point pen The mechanism of the ink discharge differs from the mechanism of the ink discharge, such as handwriting caused by the transfer of the ink to the writing surface by capillary action and penetration by the rotation of the ball of the pen tip. Because it is.
- the present inventors have paid attention to the effectiveness of the water content in a water-based ink composition for an oil-based ballpoint pen.
- Japanese Patent Application Laid-Open No. 2000-256605 proposes an oil-based bollink containing water for the purpose of making it difficult to cause unevenness in drawing line density due to directionality when writing with a ballpoint pen. ing.
- Japanese Patent Application Laid-Open No. 2001-311032 teaches that even if a ballpoint pen is stored for a long period of time, ink viscosity is unlikely to decrease due to moisture absorption, and therefore ink drops during writing and ink leakage from the tip downward are unlikely to occur.
- a water-based oil-based ballpoint paint has been proposed.
- benzyl alcohol and phenyldaricol are used.
- Benzyl alcohol and phenyldaricol are well known as high boiling organic solvents having a vapor pressure of 0.1 mmHg or less.
- the ink composition other than the solvent is Although the dissolution and dispersion of the material could be kept stable, it became clear that a problem would occur when trying to increase the amount of ink discharged from the end of the brush to increase the sharpness of the handwriting. In other words, increasing the amount of ink discharged from the end of the brush When trying to increase the clarity of the marks, the solvent evaporation speed of the ink transferred to the writing surface becomes slow.
- the present inventor has found, after research, that the permeation performance of the ink to the paper surface is controlled by containing water in a certain amount or more.
- the inventor has also found that the water content is effective in promoting the speed of evaporation of the ink solvent in the handwriting, and preventing the handwriting from bleeding and strikethrough.
- the present inventor has found that when only water and an organic solvent having a vapor pressure of 0.1 mmHg or less are used as the solvent, the dissolution stability of the water is not obtained, and the water content is appropriately increased. It was also found that since the amount cannot be increased, the moisture content does not sufficiently control the permeation performance of the ink, promote the handwriting dryness, and suppress the bleeding and strikethrough. .
- the object of the present invention is to demonstrate the effectiveness of the water content for various required characteristics, high clarity of handwriting, excellent handwriting dryness, less lacquer and strikethrough in handwriting, good writing taste, and chemically stable It is an object of the present invention to provide an oil-based ink composition for a ballpoint pen. Disclosure of the invention
- the handwriting dryness in which the solvent in the ink evaporates quickly does not match the conventional oil-based ballpoint pen ink.
- a mechanism of ink ejection, in which ink penetrates the writing surface, is provided. By imparting these characteristics, the ink ejection amount can be increased and the sharpness of the handwriting can be increased without impairing the handwriting dryness. Focusing on the above, the present inventor has arrived at the present invention.
- the ink composition for oil-based ballpoint pens of the present invention comprises: an oil-soluble dye; water as a solvent; and an organic solvent which dissolves water and has a vapor pressure of 0.5 mmHg or more at 20 ° C. Dissolve organic solvent with a vapor pressure of 0.5 mmHg or more at C20.
- An oil-based ballpoint pen ink composition comprising an organic solvent having a vapor pressure of 0.1 mmHg or less at C, wherein said water and an organic solvent that dissolves water and has a vapor pressure of 0.5 mmHg or more at 20 ° C are
- the total of the organic solvent having a vapor pressure at 20 ° C of ⁇ .5 mmHg or more and a vapor pressure of 0.1 mmHg or less at 20 ° C is 20% based on the total mass of the ink composition.
- a water content of 2.0 to 15.0% by mass with respect to the total mass of the ink composition.
- a first feature of the present invention is to provide an ink-based ink composition for a ball-point pen in order to control ink permeation performance on paper, to promote the effect of evaporating the ink solvent in handwriting, and to suppress bleeding and strikethrough on paper. It is to add water actively.
- the water content in the oil-based ballpoint pen ink of the present invention is 2.0 to 15.0% by mass, preferably 3.0 to 10.0% by mass, based on the total amount of the oil-based ballpoint ink of the present invention. If the water content is less than 2.0%, bleeding and strike-through occur on the paper surface, and the effect of suppressing blemishes and strike-through and handwriting drying properties are not sufficient. On the other hand, when the water content is more than 15.0%, the water solubility of the ink is exceeded, which causes poor writing.
- the second feature is that the solvent that dissolves and disperses the ink components is water, an organic solvent that dissolves water and has a vapor pressure of 0.5 mmHg or more at 20 ° C, and a vapor at 20 ° C.
- An organic solvent with a pressure of 0.5 mmHg or more is dissolved and an organic solvent with a vapor pressure at 20 ° C of 0.1 mmHg or less is used. Only a combination of water and an organic solvent that dissolves water and has a vapor pressure of 0.5 mmHg or more at 20 ° C will increase the amount of the solvent that evaporates, resulting in poor writing performance as a ballpoint pen.
- the dissolution stability of an ink component such as a coloring material is lacking.
- an organic solvent having a vapor pressure of 0.5 mmHg or more and an organic solvent having a vapor pressure of 0.5 mmHg or more at 20 ° C are dissolved to have a vapor pressure of 0.1 at 20 ° C.
- the combination of an organic solvent of not more than mmHg alone does not provide the effect of suppressing the permeation of the ink on paper due to the water content. For this reason, after the ink has been loaded on the paper, it is difficult to control the penetration of the ink on the paper, and penetrating or bleeding of the handwriting is likely to occur. In other words, the effect of suppressing the penetration and strikethrough due to the contained water cannot be obtained. Further, the effect of increasing the evaporation speed of the ink solvent of the handwriting due to the contained water cannot be obtained, and an appropriate handwriting drying property cannot be obtained.
- water an organic solvent that dissolves water and has a vapor pressure of 0.5 mmHg or more at 20 ° C

- the total content of these three-component solvents is 20.0 to 75.0% by mass, and preferably 35.0 to 65.0% by mass, based on the total mass of the ink composition. . If the amount is less than 20.0% by mass, the ink composition is insufficiently dissolved and dispersed, and does not function as a solvent.
- Organic solvents that dissolve water and have a vapor pressure of 0.5 mmHg or more at 20 ° C are important solvents for maintaining the stability of water, which is the active ingredient, in water. Become. This organic solvent is organically linked to the water content, and is effective for handwriting drying and paper Even if the ink discharge amount is increased by skillfully exhibiting the penetrating effect, the dryness of the handwriting is good and no strikethrough or bleeding occurs.
- the organic solvent that dissolves water and has a vapor pressure of 0.5 mmHg or more at 20 ° C is less than 3.0% by mass based on the total composition of the ink, the ink solvent evaporation amount of the handwriting will be insufficient. However, it is difficult to obtain a penetrating effect on the paper surface and a stable dissolution of water. If the content is more than 30.0% by mass, the amount of evaporation of the solvent becomes too large, resulting in poor ink stability. If left unattended, writing defects such as poor writing may occur. Therefore, the content is preferably 3.0 to 30.0% by mass.
- the organic solvent which dissolves water and has a vapor pressure of 0.5 mmHg or more at 20 ° C is not particularly limited, and is preferably a dalicol ether or an alcohol in consideration of the stability of dissolution of water.

- the organic solvent having a vapor pressure of 0.5 mmHg or more at 20 ° C was dissolved and the vapor pressure at 20 ° C was 0.1 mmH. It is necessary to employ an organic solvent of less than g.
- the organic solvent having a vapor pressure of 0.5 mmHg or more at 20 ° C. and having a vapor pressure of 0.1 mmHg or less at 20 ° C. is 10.0% based on the total amount of the ink composition.
- the content is less than It is difficult to stably maintain the dissolution and dispersion of the components, and if it exceeds 40.0% by mass, solvent evaporation is slowed down, resulting in reduced handwriting dryness. Further, since the penetration ability to the paper becomes difficult adjustment bleeding handwriting, since sometimes cause strike through, 0 1 relative to the total amount of Inki composition. 0-4 0. 0 wt 0/0, more preferably It is desirable that the content be 20.0 to 30.0% by mass.
- the organic solvent having a vapor pressure of 0.5 mmHg or more at 20 ° C is dissolved and the vapor pressure at 20 ° C is 0.1 mmHg or less.

- oil-soluble dyes Due to this technical background, it is possible to squeeze the maximum amount of addition, and to thoroughly pursue handwriting clarity, the use of oil-soluble dyes is the most effective choice. Furthermore, the adoption of oil-soluble dyes broadens the selection range of solvents, making it easier to adjust handwriting dryness, strikethrough, and bleeding.
- the addition amount of the oil-soluble dye is not particularly limited, but is 5.0 mass ° /. If less than the desired handwriting sharpness When the amount exceeds 50% by mass, the ink fluidity tends to be poor and the ink tends to be unstable over time. ⁇ 50.0% by mass is desirable.
- the ink viscosity of the oil-based ink composition of the present invention is not particularly limited, but when the ink viscosity at 20 ° C is less than 10 OmPas, bleeding or strike-through occurs.
- the lubrication performance under strong writing pressure is low, and the end of the brush is liable to wear, which may cause poor writing.
- the ink viscosity at 20 ° C exceeds 5, OO OmPas, when used as a ballpoint pen, the pole rotation resistance during writing increases, and the writing taste tends to be heavy.
