Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ink for writing instruments, and more specifically, when applied with a brush He (including drawing) on a writing object having solvent permeability,
This invention relates to a triple color ink that allows triple handwriting to be obtained. BACKGROUND ART Writing instruments using so-called edging ink, which is a mixture of metal powder pigment and fine particle pigment or dye, have been known. Also, in recent years 1
A triple color ink (Japanese Patent Application Laid-open No. 5.9/1962/6271) consisting of two types of pigments and a dye having different particle sizes has become known. However, since the triple color ink uses two types of pigments with different particle sizes, the particle size of the large particle size pigment must be increased, and as a result, when used in writing instruments, it is difficult to clog the pen tip. There was a problem that it was easy to occur.

As a result of intensive research, the inventors of the present invention came up with a technical approach to creating a triple color ink using a combination of two types of pigments and one type of dye.

The present invention has been completed by solving the above-mentioned problems through a technical approach to triple color ink using a combination of one type of pigment and two types of dye. That is, the present invention provides an organic solvent system consisting of a metal powder pigment, an oil-soluble dye, and an organic solvent that is incompatible with water; The gist of this paper is a triple color ink that is characterized by the following.

The ink of the present invention has the above structure.

An organic solvent system in which metal powder pigments are dispersed and oil-soluble dyes dissolved, and an aqueous system in which water-soluble dyes are dissolved are mixed and dispersed.
When writing on a writing material that has soluble permeability, the organic solvent system has high permeability, so it penetrates and diffuses over a relatively wide area on the surface of the writing material. Create a handwriting with an outline of oil-soluble dye. At the same time, since water-based systems have lower permeability than organic solvent-based systems, they permeate and diffuse into a relatively narrow area on the surface of the object to be written. Form the contour.

Therefore, the handwriting that is formed has an outline of a water-soluble dye centered on the metal powder pigment, and furthermore, an outline of an oil-soluble dye.

The triple colored handwriting is 1-), and it is thought that this structure allows the use of metal powder pigments with relatively small particle diameters and prevents clogging of the pen tip.

Next, each component of the present invention will be explained.

The components that make up the organic solvent system are metal powder; top material;

These are oil-soluble dyes and organic solvents that are incompatible with water.

Metal powder pigments include brass powder and aluminum powder.

Examples include copper powder, and colored versions of these can also be used, and the amount used is 10 to 4 times the total amount of ink.

Examples include CI 5olvent Black 5, which can be used singly or in a mixture of two or more, and the amount used is preferably 2 to 20 voids based on the total amount of ink.

Examples of organic solvents that are incompatible with water include aromatic hydrocarbon solvents such as toluene and quinoa, aliphatic hydrocarbon solvents such as n-hexane and n-hebutane, and esters such as butyl acetate and amyl vinegar. These include solvents, which can be used alone or in combination of two or more, and the amount used is preferably 40 to 7041j 17L% based on the total amount of ink.

Next, the components that make up water slag are water-soluble dyes and water.
