Description

  The present invention is a ballpoint pen refill in which a ballpoint pen tip holding a ball rotatably is mounted at the tip of an ink containing cylinder directly or via a chip holder, and the same components are the same type of shaft cylinder Relates to a ballpoint pen refill group.

  Conventionally, as disclosed in Japanese Patent Application Laid-Open No. 10-264576, “Ball Pen Refill”, a ballpoint pen tip that rotatably holds a ball is attached to the tip of an ink containing cylinder directly or via a tip holder, and a ballpoint pen is placed inside the tip. Ballpoint pen refills that contain direct ink are well known.

  In addition, the ballpoint pen refills are developed as a group of ballpoint pen refills arranged on the same type of shaft cylinders, by developing different ball diameters and different ink colors such as black, red, blue, etc. ing.

In this way, ballpoint pen refills of different colors are provided as a group of ballpoint pen refills arranged on the same type of shaft cylinder, so that colors corresponding to the colors of the purpose of use and the paper to be written on are selected and used. . Among them, black is used more frequently and the production volume is much higher than other colors.
JP-A-10-264576

  By the way, even if it is the same hue, the color feeling received by saturation and lightness differs. For example, since red, orange, and yellow are warm colors, black with such a color is warm even if it is black. On the other hand, blue-green, blue, and blue-purple are cold-colored, so black with such a color has a cold and calm feeling. Also, since warm colors are advancing colors that feel closer than they actually are, blacks with such colors are different in distance from blacks with cold colors that are farther than actual colors.

  However, as described above, the ballpoint pen refill group disposed on the same type of cylinder is a group having a plurality of ballpoint refills of different colors such as black, red, and blue, but there is only one type of black. It was.

  The present invention has been made in view of these facts, and provides a ball-point refill group that contains a plurality of black ball-point pen inks in a ball-point refill group disposed in a shaft cylinder of the same type.

  The present invention is a ballpoint pen refill in which a ballpoint pen tip holding a ball rotatably is mounted at the tip of an ink containing cylinder directly or via a chip holder, and the same components are the same type of shaft cylinder In the ballpoint pen refill group, the black ink for the ballpoint pen is accommodated in each ink storage cylinder of the ballpoint pen refill group, and each black ballpoint ink has a color difference.

  The ballpoint pen ink contained in each ink containing cylinder of the ballpoint pen refill group comprises a kind of black ballpoint pen ink composed of a black colorant, the black colorant, and a colored colorant excluding the black colorant. It is another kind of black ballpoint pen ink.

  Further, the other type of ballpoint pen ink comprising the black colorant and the colored colorant excluding the black colorant has a content of the black colorant of A mass%, and the colored colorant excluding the black colorant. When the content of is B mass%, the relationship of 1.0 ≦ A / B ≦ 10.0 is satisfied.

  Furthermore, the other kind of black ballpoint pen ink comprising the black colorant and the colored colorant excluding the black colorant has a saturation in the hue composed of the color of the black colorant and the color of the colorant. It is characterized by being 10% or more and less than 50%.

  Furthermore, another type of ballpoint pen refill containing the black colorant and a colored colorant excluding the black colorant, which contains another type of black ballpoint pen ink, is substantially the same color as the black colorant and the black colorant. It has substantially the same color portion as the colored colorant excluding.

  Furthermore, the ink consumption of the refill for the ballpoint pen is 50 mg to 300 mg / 100 m.

  The present invention was able to provide a ballpoint pen refill group containing a plurality of black ballpoint pen inks in the ballpoint pen refill group disposed on the same type of shaft cylinder.

  The first feature of the present invention is that, in a ballpoint pen refill group arranged in a shaft cylinder of the same type, the ballpoint pen ink contained in each ink containing cylinder of the ballpoint pen refill group is black, and each ballpoint pen ink is It has a color difference.

  Although it can be realized by changing the lightness to have a color difference in black, it contains a kind of ink for a ballpoint pen made of a black colorant, a black colorant, and a colored colorant excluding the black colorant. This is most preferable because black with other colors can be realized. Note that the color of the black colorant and the color of the colorant excluding the black colorant are colors exhibited after dissolution or dispersion in the ballpoint pen ink.

  In addition, about a color difference, it calculates | requires a color difference by measuring other types of ink for ball-point pens with a color difference meter (Tokyo Denshoku Co., Ltd. make, TC-3600), for example, on the basis of a kind of ink for ball-point pens. Can do.

  As the black colorant used in the present invention, a dye and / or a pigment can be used. As the dye, a direct dye, an acid dye, a basic dye, or the like can be used. Examples of the pigment include inorganic, organic and processed pigments. The content of these black colorants is preferably 1% by mass to 20% by mass with respect to the total amount of the ink composition, and more preferably 1% by mass to 10% by mass in consideration of ink aging stability.

  In addition, as the colorant other than the black colorant used in the present invention, a colorant other than black such as blue, red, yellow, and green can be used, and a dye and / or a pigment can be used. As the dye, a direct dye, an acid dye, a basic dye, or the like can be used. Examples of the pigment include inorganic, organic and processed pigments. These dyes and pigments can be used in combination of two or more, the content is less than the black colorant described above, and 0.1% by mass to 5.0% by mass with respect to the total amount of the ink composition Is preferable, and 0.5% by mass to 4.0% by mass is most preferable.

  In addition, it is most preferable to use a dye for the black colorant and the colored colorant excluding the black colorant. This is because the dye has good dissolution stability in ink. Further, even if two or more kinds of dyes are added, the solution is stable and the color tone is good for a long time.

  Specifically, as dyes used in the black colorant, Direct Black 17, 19, 22, 22, 32, 38, 51, 71, 154, 168, 195, Acid Black 1, 2, 24, 26, 31, 52, 107, C.I. I. Basic black 2 etc. can be illustrated.

  Another kind of black ballpoint pen ink consisting of a black colorant and a colored colorant excluding the black colorant is black-colored in a hue consisting of the color of the black colorant and the color of the colored colorant excluding the black colorant. When the saturation of the coloring agent alone is 0% and the saturation of the colored coloring agent alone excluding the black coloring agent is 100%, if the saturation is less than 10%, the coloring of the black coloring agent is strong and the black coloring agent It is difficult to judge the color of the colorant except for the colorant, and if it is 50% or more, the colorant of the colorant excluding the black colorant has a strong color and is difficult to visually recognize black. Preferably, 25% or less is most preferable.

  Further, when the black colorant is A mass% and the colored colorant excluding the black colorant is B mass%, the color tone of the colored colorant excluding the black colorant is A / B <1.0. Is strong and difficult to see in black. When A / B> 10.0, the color of the black colorant is strong, and the color of the colorant other than the black colorant is difficult to judge. Therefore, the relationship between A and B is preferably 1.0 ≦ A / B ≦ 10.0, and most preferably 2.0 ≦ A / B ≦ 5.0.

  In addition, other types of black ballpoint pen inks composed of a black colorant and a colored colorant excluding the black colorant are the colors of the black colorant alone and the color composed of the color of the black colorant and the color of the colorant. When the brightness is 0% and the brightness of white is 100%, if the brightness is greater than 25%, a whitish color is obtained. Therefore, the brightness of each ballpoint pen ink is preferably 25% or less.

  In addition, in consideration of dissolution stability, evaporative drying prevention, etc., water-soluble organic solvents such as glycerin and ethylene glycol, and improvement in lubricity are considered. Salts, pH adjusters such as triethanolamine, humectants such as urea and sorbit, rust inhibitors such as benzotriazole, and antibacterial agents such as 1,2 benzoisothiazolin-3-one can be added. In addition, dispersants can be added as appropriate.

The ballpoint pen refill is mounted directly through the ink containing cylinder 2 and filled with the ballpoint pen ink 6 and the grease-like ink follower 7 obtained by the following ink composition 1 in the ink containing cylinder 2 and fitted with a black tail plug. 1 was produced.

Ink formulation 1
Water 59.5 parts by mass Water-soluble organic solvent (ethylene glycol) 20.0 parts by mass Black colorant (Direct Black 154) 7.0 parts by mass Lubricant (phosphate surfactant) 0.5 parts by mass Lubricant (Fatty acid) 0.5 parts by weight pH adjuster (triethanolamine) 5.0 parts by weight Moisturizer (urea) 5.0 parts by weight Moisturizer (Sorbit) 1.5 parts by weight Antibacterial agent (1,2 benzoisothiazoline -3-one) 0.5 parts by mass Rust inhibitor (benzotriazole) 0.5 parts by mass Shear thinning agent (succinoglycan) 0.1 parts by mass Shear thinning agent (xanthan gum) 0.2 parts by mass Shear thinning agent (cross-linked acrylic acid polymer) 0.2 parts by mass

  Ink formulation 1 is first prepared by heating and stirring a black colorant, water, a water-soluble organic solvent, a lubricant, a moisturizer, a pH adjuster, an antibacterial agent, and a rust inhibitor with a magnet hot stirrer. . Then, while heating the base ink prepared above, after adding a shear thinning agent and thoroughly mixing and stirring until a uniform state using a homogenizer stirrer, filtration using a filter paper, Ballpoint ink 6 is obtained.

  Similarly to the ballpoint pen refill 1, the ballpoint pen refills 11 and 21 have ballpoint pen tips 14 and 24 each having a ball diameter of φ0.7 mm rotatably held at the tip portions of the ink storage cylinders 12 and 22, respectively, 23 is attached. Since the component parts such as the outer diameter and the total length of the ballpoint pen refills 1, 11, and 21 are the same, they are not shown, but they can be disposed on the same type of shaft cylinder body.

  The ballpoint refill 11 directly contains black ballpoint pen ink of ink composition 2, and the ballpoint refill 21 directly accommodates black ballpoint ink of ink composition 3. Each ink formulation, ink consumption, and ink viscosity are as shown in Table 1.

Table 1

  Ink for ballpoint pen 6 is black for black colorant, Ink for ballpoint pen 16 is black for black colorant, yellowish color of colored colorant, Ink for ballpoint pen 26 is black for black colorant In addition, since it becomes a bluish color of the colored colorant, it is a ballpoint pen refill group containing ballpoint pen ink having a color difference.

  still. The ballpoint pen refills 11 and 21 include parts having the same color as the black colorant, such as a black tail plug and a yellow tip holder, and parts having the same color as or similar to the colorant. It is preferable to differentiate, and it is most preferable to apply two colors to individual parts in order to prevent mixing.

  Also, the more ink consumption per 100 m, the easier it is to visually recognize the handwriting. Specifically, the ink consumption per 100 m is 50 mg or more. However, if there is too much ink consumption, new problems such as scratching and penetrability may occur, so the ink consumption per 100 m is 50 mg to 300 mg, preferably 80 mg to 250 mg.

In the present embodiment, for the sake of convenience, water-based ballpoint pen ink imparted with shear thinning is used, but there is no particular limitation such as oil-based ink or water-based ink. Also, the ink viscosity is not particularly limited, but if the viscosity at 20 ° C. and a shear rate of 384 sec −1 (100 rpm) exceeds 100 mPa · s, it is difficult to increase the ink consumption per 100 m. s or less, preferably 70 mPa · s or less. Moreover, since it will be easy to generate | occur | produce from a chip | tip tip if it is less than 10 mPa * s, it is most preferable to set it as 10 mPa * s or more and 100 mPa * s or less.

The ink viscosity can be measured using a Brookfield DV-II viscometer (No. 27 rotor) in an environment of 20 ° C. and a shear rate of 384 sec −1 (100 rpm). Although not shown, it is most preferable to incorporate a coil spring that presses the ball into the chip to suppress ink leakage from the tip of the chip.

  The ballpoint pen refill group arranged on the same type of shaft cylinder of the present invention is not limited to the type of ink and the presence / absence mechanism, so it can be widely used, such as knock type ballpoint pen, cap type ballpoint pen, etc. Like a writing instrument, a plurality can be accommodated in the same shaft tube.

It is a longitudinal cross-sectional view which shows the ball-point pen refill of Example 1. FIG. It is a figure which shows another ball-point pen refill.
