The present invention relates to a water-based glossy ink composition in which a pigment is easily redispersed, which is used by filling in a writing implement such as a brush pen or a coating implement.

[0002]

2. Description of the Related Art Conventionally, in an aqueous ink composition, at least a pearl pigment or a metal powder pigment has been used as a pigment in an ink for obtaining glossy handwriting. Aqueous inks using pearl pigments are disclosed in Japanese Patent Publication No. Hei 5-45633 and Japanese Patent Laid-Open Publication No. Hei 5-117569. Aqueous inks using metal powder pigments are disclosed in Japanese Patent Publication No. Hei 7-35491 and Japanese Patent Laid-Open Publication No. Hei 1-301772.

[0003] Among the above publications, Japanese Patent Publication No. 45633/1993 discloses a opacity imparting pigment selected from titanium oxide and a pearl pigment composed of mica pieces coated with titanium oxide, an alkali-soluble water-soluble resin, a rosin ester emulsion, An aqueous fluorescent pigment ink for a marking pen containing a daylight fluorescent pigment as an essential component is described.

JP-A-5-117569 discloses a pearl pigment having an average particle diameter of 5 to 100 μm in an amount of 5 to 50% by weight based on the total amount of the ink, and a dispersant / fixing agent in an amount of 5 to 30% based on the total amount of the ink. A pearl water-based ink composition is described which contains a dye or a pigment as a colorant in an amount of 0 to 20% by weight based on the total amount of the ink.

On the other hand, Japanese Patent Publication No. 7-35491 discloses that
An aqueous metallic color ink containing an aluminum powder pigment, an amphoteric compound, a resin emulsion and water as essential components is described.

[0006] Japanese Patent Application Laid-Open No. 1-301772 discloses a metal powder pigment composed of brass powder and / or copper powder, a dispersant, water, an aromatic amine having a specific structure as a rust preventive or a derivative thereof. Aqueous metallic pigment inks are described.

By the way, when an aqueous ink using a pearl pigment or a metal powder pigment is used by filling it into a writing implement, it is often used after applying an external force, such as shaking the writing implement a plurality of times immediately before writing. This is because the specific gravity of the pigment is higher than that of an organic pigment generally used for aqueous inks. That is, the pearl pigment and the metal powder pigment easily separate and settle in the ink, and when stored, are divided into a supernatant liquid and a solid content containing the pigment. Therefore, unless an external force such as shaking is applied immediately before use, the pigment concentration in the ink will not be uniform, and handwriting with a uniform concentration cannot be obtained.

[0008]

However, when an aqueous ink using a pearl pigment or a metal powder pigment is left for a long period of time, the pigment concentration in the ink may not be uniform even if the writing implement is shaken. . This is because the pearl pigment and the metal powder pigment are settled and separated, and then the sediment containing the pigment is hardened to form a so-called hard cake, which makes it difficult to re-disperse the ink in the ink.

An object of the present invention is to provide an aqueous gloss ink composition containing a pearl pigment or a metal powder pigment, which does not form a hard cake even when stored for a long period of time.

In the present invention, the term "redispersion" means that a sediment containing a sedimented and separated pigment is applied to an ink by applying an external force such as shaking the writing instrument or the applicator with a writing instrument or an applicator. It shows that it is dispersed again uniformly.

[0011]

According to the present invention, there is provided an aqueous glossy ink composition comprising at least a pigment, a dispersant, a resin and water, wherein the pigment is at least a pearl pigment and / or a metal powder pigment, Contains at least a fatty acid ester of polyoxyethylene diglycerin borate.

Hereinafter, the present invention will be described in detail. As the pigment used in the aqueous glossy ink composition of the present invention, at least a pearl pigment and / or a metal powder pigment are used. This pearl pigment and / or metal powder pigment is used for the purpose of imparting gloss to handwriting. Pearl pigments include natural products such as fish scale foil, basic lead carbonate, bismuth oxychloride, natural mica whose surface is coated with metal oxide, and synthetic mica whose surface is coated with metal oxide. There are synthetic products. In general, from the point of view of availability and safety,
A material in which the surface of natural mica is coated with a metal oxide and a material in which the surface of synthetic mica is coated with a metal oxide are often used. Pearl pigments have a mirror-like luster other than color tone,
It is a pigment that has a pearly luster. The color tone of the pearl pigment mainly depends on the type of the metal oxide coated on the surface. For example, a metal oxide using titanium oxide or aluminum oxide has a white silver color tone.
In the case where iron oxide is used or the case where a titanium oxide layer and an iron oxide layer are provided, the color tone becomes gold, red, or copper due to absorption of a partial wavelength region by the iron oxide layer. In addition, those coated with chromium oxide or cobalt titanate,
The color becomes green. In addition, in the case of pearl pigment, when the metal oxide used for coating is titanium oxide, light in a part of the wavelength region of the incident light is reflected by the thickness of the titanium oxide layer,
In some cases, light in a wavelength region corresponding to a complementary color can be transmitted to give colored handwriting. The specular gloss of the pearl pigment is such that, at each boundary between the metal oxide layer with a high refractive index, the mica layer with a low refractive index, and the medium around the pearl pigment, the incident light is specular due to the difference in the refractive index of each layer. Obtained by reflection. The pearlescent luster of the pearl pigment is the same as that of reflected light from the pearl calcium carbonate layer and protein layer alternately laminated because the boundaries within one pearl pigment are parallel and the reflected light is combined. It is obtained by performing multiple reflections in a typical manner. As a commercially available pearl pigment, Iriodin 100 (particle size: 10 to 60)

In the case of pearl pigments, gloss is produced by regular multiple reflections on parallel surfaces having different refractive indices. Therefore, if the particle diameter is smaller than 5 μm, the gloss becomes weak. Therefore, its particle size is 5μ
The above is preferred.

[0013] Metal powder pigments include aluminum powder, brass powder, stainless steel powder, tin powder, zinc powder, bronze powder, nickel powder, copper powder, gold powder, silver powder, and the like, mixed powders thereof, and alloys of these metals. There is powder. Further, in the reflection on metal, the specular reflectance changes greatly depending on the wavelength, so that the specularly reflected light appears colored. This gives a metallic luster peculiar to each metal. Therefore, when a metal powder pigment is used, the handwriting has a luster peculiar to the metal. That is, the color obtained by the metal powder pigment is almost limited to gold, silver, copper and red. When metal powder pigments are used, aluminum powder pigments are generally used for silver, and copper powder and copper alloy powder pigments are used for gold, copper and red.

Aluminum powder pigments are prepared by stamping a piece of aluminum with a lubricant such as stearic acid in a stamp mill, or by spraying aluminum powder obtained by a spraying method in a drum, a lubricant and a suitable liquid onto a steel ball. It is obtained by a ball mill method of charging and pulverizing together, and a scaly one is preferable. Commercially available aluminum powder pigments include Super Fine No. 2200

The above metal powder pigments can be used alone or in combination of two or more.

Further, since the metal powder pigment has luster having a color peculiar to the metal, when obtaining a gold, copper or glossy red handwriting, the gold and / or copper and / or red color is used. Or a combination of a silver pearl pigment and a gold and / or copper and / or red metal powder pigment. When a silver handwriting is obtained, it can be obtained by a combination of a silver pearl pigment and a silver metal powder pigment. In the case of obtaining a glossy handwriting of another color, a glossy green handwriting can be obtained by combining a green pearl pigment obtained by coating mica with chromium oxide or cobalt titanate and a silver metal powder pigment.

The amount of the pearl pigment and / or metal powder pigment used in the present invention ranges from 1.0 to 40% by weight, preferably from 2.0 to 30% by weight, based on the total amount of the aqueous glossy ink composition. Can be used with

If the particle diameter is larger than 100 μm, the ink may be clogged at the pen tip made of a fiber of a marking pen or a brush pen or a sponge-like communicating porous body, and writing may not be performed.

The dispersant used in the aqueous gloss ink composition of the present invention must contain at least a fatty acid ester of polyoxyethylene diglycerin borate. The purpose is that the pigment contained in the ink does not form a hard cake even after settling during storage, and the settling pigment is easily redispersed by shaking the writing or applicator. This is to make it possible. Specific examples of the fatty acid ester of polyoxyethylene diglycerin borate include Emalbon T-20, T-40, T-60, T-80 and T-160 (all manufactured by Toho Chemical Industry Co., Ltd.) ).

Water-insoluble resins and the like can be mentioned. The water-insoluble resin is used in the form of an aqueous emulsion.

Water is used as the main solvent.

In producing the ink of the present invention, various conventionally known methods can be employed. For example, it can be easily obtained by blending the above respective components and stirring and mixing with a stirrer such as a turbo mixer or a Henschel mixer, or mixing and grinding with a disperser such as a ball mill.

In addition to the above components, various additives conventionally used in aqueous ink compositions can also be used. For example, a water-soluble organic solvent can be used for the purpose of preventing the ink from drying at the pen tip and preventing the ink from freezing at low temperatures. Specifically, glycols such as ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, dipropylene glycol, polyethylene glycol, 1,3-butylene glycol, thiodiethylene glycol, 1,5-pentanediol, and glycerin; Monomethyl ether, diethylene glycol monomethyl ether,

YELLOW BLUE 2G (all manufactured by Toyo Ink Co., Ltd.) and the like. The weight ratio between the silver pearl pigment and / or the silver metal powder pigment and the colorant is as follows.
The colorant is preferably 3.0 or less. Further, since aluminum powder pigments previously colored with a coloring agent are commercially available as colored aluminum powder pigments, they can also be used.

Incidentally, the metallic powder pigment reacts with water and loses its luster. This is because the metal powder pigment is corroded by the reaction with water to produce rust. For this reason, metal powder pigments
In order to impart a rust-preventive effect, the surface is treated with a fatty acid, phosphoric acid or a salt thereof. However, when a metal powder pigment is used in an aqueous ink, the surface treatment alone is not sufficient because it is immersed in water for a long time. Therefore,
Many inventions have been proposed for suppressing the reaction between a metal powder pigment and water. For example, in the case of aluminum powder pigments, JP-A-6-192610 discloses that a perfluoroalkyl phosphate and / or a perfluoroalkyltrimethylammonium salt is used in combination. In addition, Japanese Patent Application Laid-Open No. Hei 8-209053 discloses that N-fatty acid acyl-L-glutamate is added. As for brass powder and / or copper powder pigment, JP-A-1-301772 discloses a method of adding an aromatic amine or a derivative thereof. Further, a method of subjecting an aluminum powder or a brass powder to a plasma treatment is disclosed in JP-A-59-138280. The water-based glossy ink composition of the present invention is used to prevent the metal powder pigment used from reacting with water and losing the luster of the metal powder pigment.
The invention described in the above publication can be adopted.

[0028]

The pigment used in the aqueous glossy ink composition of the present invention has a plate-like shape having a small thickness and a large planar area. When the pigment settles, it is expected to form a layered structure in which the planes of the pigment face each other and are stacked. In this layered structure, since the area of the part where the pigments are in contact with each other is large, it is considered that the resulting contact resistance is also large. Therefore, this structure is in a stable state, and it is considered that it is difficult to break the structure by applying a small external force. However, the dispersant used in the aqueous gloss ink composition of the present invention reduces the contact resistance between pigments caused by the layered structure by adhering to the surface of the pigment used. That is, the presence of the dispersant used in the aqueous glossy ink composition of the present invention between the layered structures formed by the pigments reduces the contact resistance between the pigments. To make it easier to break. Therefore, the dispersant of the present invention has the effect of imparting fluidity to the attached pigment, even after the pigment has settled in the ink, by applying an external force such as shaking to the writing instrument or the applicator filled with the ink. It is considered that the pigment can be redispersed.
