  On the other hand, a variety of aqueous coatings using a combination of scaly gel colored particles having a size of 1 to 4 mm and a thickness of 0.1 to 0.2 mm and colored or colored spherical fine particles dispersed in an aqueous medium A composition is provided (Patent Document 2).

JP 7-247450 A

However, Patent Document 1 is not an ink composition that forms a spotted writing line (handwriting). Patent Document 2 discloses a technique for forming a multicolored pattern having different color tones using scaly gel colored particles. However, it can form a writing line (handwriting) of a spotted pattern, and a writing instrument, particularly a ballpoint pen. It is not a color material composition applicable to the above.
Further, a color material composition that forms a clear spotted makeup coating film and a cosmetic applicator including the color material composition have not yet been provided in the cosmetic field.

  An object of the present invention is to provide a color material composition such as ink, drawing material, and cosmetics that can form a writing line (handwriting) or a coating film of a speckled pattern, and is used for a writing instrument, a cosmetic applicator, etc. It is in.

The present invention is a color material composition used in an applicator provided with an outflow passage for the color material composition,
In the color material composition, elastically deformable particles are contained in a dispersed state.

  As the elastically deformable particles, for example, gel particles are preferable, and particles made of agar are particularly preferable. The elastically deformable particles are preferably particles having a diameter in the range of 50 μm to 1000 μm and having a diameter larger than the smallest gap in the outflow channel, but are not limited thereto.

  In addition, an ink composition in which the particles are colored and contains a plurality of color particles is preferable.

  In the present invention, “elastically deformable” means that particles having a diameter larger than the smallest gap in the outflow passage are elastically deformed in the gap portion when passing through the outflow passage. It means that it can be leaked. For example, taking a writing instrument or a cosmetic applicator having a control means such as a ball or a pin for controlling the outflow of the composition as an example, it is constituted between the wall surface of a pen tip or the like loaded with this control means. This means that particles having a diameter the same as or larger than the smallest gap can flow out of the gap while deforming at the gap portion when passing through the gap. Further, for example, a writing container or a cosmetic applicator that is formed of a tube-like container having a color material composition outlet (outflow passage) and squeezes the color material composition out of the outlet (outflow passage). It means that particles having a diameter the same as or larger than the smallest gap among them can flow out of the gap while deforming at the gap portion when passing through the gap (gap).

According to the present invention, even a particle having a diameter larger than the gap can pass through the outflow passage, so that a speckled writing line (handwriting) is formed with a size that can be clearly recognized. be able to.
Therefore, for example, a writing instrument including a pen tip and an ink cylinder containing ink, and a color material containing elastically deformable particles having a diameter of 50 to 1000 μm in a dispersed state is included in the ink cylinder. Housed writing instruments can be employed.
For example, a ballpoint pen in which this ink is contained in an ink cylinder and the ink flows out by rotation of the ball, and even if the gap formed by the ball and the wall surface of the ballpoint pen tip is narrow, the particles are elastic at the portion. The ink composition can be included in the ink composition because it deforms and flows out with the ink flow without stopping the ink flow. is there.

  Further, for example, even if a gap (ink flow path) constituted by a valve body such as a ball to which a resilient force is applied, and the valve body pressed by pressing the valve body and the wall surface of the chip is narrow, Since the particles are elastically deformed at the portion and flow out with the ink flow without stopping the ink flow, particles having a diameter larger than the gap of the size capable of forming a spotted pattern are contained in the ink composition. Can be included.

The present invention is not limited to the above ballpoint pen, and the present invention is a writing instrument including a pen tip having an ink outflow path having an ink outflow control means, and an ink cylinder containing ink,
The ink contains elastically deformable particles in a dispersed state,
A writing instrument may be employed in which the particles include particles having a diameter equal to or larger than the size of the smallest gap in the ink outflow path of the nib. For example, a writing instrument provided with a pin-like material constituting a valve structure as the ink outflow control means.

Further, according to the present invention, for example, a cosmetic applicator composed of a tube-shaped container that is filled with a cosmetic composition and has an outflow hole that forms an outflow passage of the cosmetic composition at the tip,
In the cosmetic composition, particles having a diameter of 50 to 1000 μm that can be elastically deformed are contained in a dispersed state,
The particles can be applied to a cosmetic applicator containing particles having a diameter equal to or larger than the diameter of the outflow hole.

<Elastically deformable particles>
The particles used in the present invention are not particularly limited as long as they are elastically deformable particles. Specific examples of elastically deformable particles include particles (gel particles) such as agar, carrageenan, gellan, calcium alginate, sodium alginate, gelatin, albumin, casein, polyvinyl alcohol, and acetylated polyvinyl alcohol. it can. Of these, agar and gelatin particles are preferred. Moreover, it is preferable that the said particle | grain uses the gel particle of a water-containing state. By using gel particles in a water-containing state, the elastic deformability is improved, and even gel particles with a large particle diameter constituting a spotted pattern are not easily settled in the aqueous composition and are well dispersed. The gel particles can be thinned with drying after writing or after coating, and a smooth writing line or coating film can be formed as a spotted pattern.

  The present particles are preferably contained in an amount of 0.1 to 50% by weight, more preferably 1 to 30% by weight, based on the total amount of the present colorant composition. When the present particles are contained in an amount exceeding 50% by weight based on the total amount of the composition, the blending amount is too large, so that it is difficult for the particles to flow out from the nib or the outflow hole. On the other hand, if the present particles are less than 0.1% by weight with respect to the total amount of the composition, since the blending amount is too small to be visually recognized, it becomes difficult to form a spotted pattern on a writing line or coating film.

The particle diameter of the particles used in the present invention is not particularly limited as long as they are elastically deformable particles. For example, the diameter may be 50 μm or more, preferably 100 μm or more, more preferably 200 μm or more, and elastically deformable particles having a diameter larger than the smallest gap in the outflow path of the coloring material composition are preferable. By employing such particles, it is possible to form a writing line or a coating film having a clearer spot pattern. The upper limit of the particle diameter is not particularly limited, but particles having a diameter of 1000 μm or less are preferable because of the relationship with the outflow path of a writing instrument such as a ballpoint pen having an outflow path of the color material composition and the applicator such as a cosmetic applicator.
In addition, it is difficult to form a spotted pattern with particles having a diameter of less than 50 μm. Particles with a diameter of 1000 μm or more are difficult to flow out from the pen tip or the like. In addition, even if it is a particle | grain with a diameter less than 50 micrometers, when it contains with the particle | grain in the range of 50 micrometers-1000 micrometers in diameter, it can apply as an ink composition of this invention. Particles having a diameter in the range of 200 μm to 1000 μm are preferable for forming a spotted pattern on a writing line or a coating film. Note that particles having a diameter in these ranges can be classified with a mesh or the like.

It is preferable to color the particles. For coloring, for example, a colorant is blended in the gel forming raw material, and after gelation, it is obtained by pulverizing to the predetermined particle size. The colorant is not particularly limited, for example, a base colorant described later is used, but a fluorescent colorant, for example, can also be used.
It is also possible to prepare particles using a plurality of colorants having different colors and to use particles of a plurality of colors in the composition. In this case, a writing line or the like having a spot pattern in which spots of different colors are scattered can be formed.
Preferred gel particles are water-containing gel particles containing a colorant, and more preferred gel particles are a gel particle containing a colorant, a dispersant (pigment dispersant) and water. The gel particles can contain a water-soluble organic solvent such as ethylene glycol and an alkali component such as sodium hydroxide.

<Binder component>
In the present invention, a synthetic resin emulsion can be used to disperse the particles and fix them on the writing line. The synthetic resin emulsion is preferably contained in the color material composition in a solid content of 30 to 70% with respect to the total amount of the composition. Examples of synthetic resin emulsions include acrylic resin emulsions, styrene acrylic resin emulsions, alkyd resin emulsions, and urethane resin emulsions.

Specifically, examples of the acrylic resin emulsion include a trade name “Nicazole FX138Y” (manufactured by Nippon Carbide), a trade name “Nicazole RX242A” (manufactured by Nippon Carbide), and a trade name “Movinyl LDM7520” (Clariant Polymer). For example). Moreover, as a styrene acrylic resin emulsion, a brand name "Boncoat NST100" (made by Dainippon Ink Co., Ltd.) and a brand name "Movinyl 972" (made by Clariant Polymer Co., Ltd.) can be exemplified. Examples of the alkyd resin emulsion include trade name “Watersol CD520” (Dainippon Ink Co., Ltd.), and examples of the urethane resin emulsion include trade name “Superflex 500” (Daiichi Kogyo Seiyaku Co., Ltd.). .
In particular, acrylic emulsions and styrene acrylic emulsions can be suitably used. Two or more kinds of emulsions can be mixed and used.

  The content of the resin emulsion is preferably 30 to 70% by weight in terms of solid content and more preferably 35 to 55% by weight in terms of solid content with respect to the total amount of the color material composition. When the resin emulsion is less than 30% by weight in solid content, fixability of the particles to a writing line (handwriting) or a coating film is lowered. When the resin emulsion exceeds 70% by weight in solid content, the resin particles are excessively present, so that the temporal stability of the color material composition is lowered.

  Moreover, in this invention, in order to disperse | distribute the said particle | grain and to fix it to a writing line, water-soluble resin can be used individually or with the said synthetic resin emulsion. Examples of the water-soluble resin include cellulose resins such as carboxymethyl cellulose, hydroxymethyl cellulose, and methyl cellulose, acrylic resins and styrene acrylic resins (including copolymers), vinyl resins such as polyvinyl alcohol and polyvinyl pyrrolidone, and gum arabic. And dextrin.

  The content of the water-soluble resin is preferably from 0.1 to 50% by weight in terms of the solid content and more preferably from 0.5 to 30% by weight in terms of the solid content based on the total amount of the color material composition. When the water-soluble resin is less than 30% by weight in solid content, the fixability of the particles to a writing line (handwriting) or a coating film is lowered. When the resin emulsion exceeds 70% by weight in solid content, the resin particles are excessively present, so that the temporal stability of the color material composition is lowered.

<Viscosity modifier>
In the present invention, it is preferable to use a viscosity modifier in order to adjust the viscosity of the color material composition (ink composition). For example, polysaccharides such as welan gum, rhamsan gum, alka gum, and xanthan gum can be used as a viscosity modifier (thickener). Alkagam is preferred as the polysaccharide.

  The content of the polysaccharide is preferably 0.05 to 0.5% by weight, more preferably 0.1 to 0.5% by weight, based on the total amount of the color material composition. When the said polysaccharide is less than 0.05 weight% with respect to the coloring material composition whole quantity, the dispersibility of the said particle | grain will deteriorate. When the said polysaccharide exceeds 0.5 weight% with respect to the coloring material composition whole quantity, a coloring material composition becomes high viscosity and it becomes difficult to flow out from outflow paths, such as a nib.

  In the present invention, as a viscosity adjusting agent other than polysaccharides, for example, polyacrylic acids such as polyacrylic acid and cross-linked polyacrylic acid, and celluloses such as carboxymethylcellulose, hydroxymethylrose, and methylcellulose can be used. . In particular, cross-linked polyacrylic acid is preferred.

  The content of the viscosity modifier such as the polyacrylic acid type and the cellulose type is preferably 0.05 to 5% by weight, and more preferably 0.1 to 5% by weight with respect to the total amount of the color material composition. When the viscosity modifier such as polyacrylic acid type or cellulose type is less than 0.05% by weight based on the total amount of the color material composition, the dispersibility of the particles is deteriorated. When the viscosity adjusting agent such as the polyacrylic acid type or the cellulose type exceeds 5% by weight with respect to the total amount of the color material composition, the color material composition becomes highly viscous and hardly flows out from the outflow passage such as a pen tip.

As a preferable color material composition of the present invention,
For the total amount of the color material composition,
a) Particles made of agar with a diameter of 50 to 1000 μm 1 to 50% by weight
b) Acrylic or styrene acrylic synthetic resin emulsion (solid content)
