Description of the Related Art Conventional writing instruments are roughly classified into liquid writing instruments such as marking pens and ballpoint pens, and solid writing instruments such as pencils and crayons, which have their respective advantages and disadvantages. While a liquid writing instrument is excellent in drawing properties, it may cause writing defects due to changes over time such as evaporation of a solvent, aggregation and precipitation of a pigment, and requires a more complicated mechanism than a solid writing instrument. Further, the solid writing instrument does not cause writing defects due to changes over time like the above-mentioned liquid writing instrument,
It has disadvantages such as rough drawn lines and poor adhesion to writing objects. Further, in order to improve the respective disadvantages of both the liquid and solid writing instruments, various writing instruments have been proposed in which gelling agents are used and the characteristics such as drawability are utilized. For example, JP-A-54-81925, JP-B-54-23618, JP-B-55-18474 and JP-B-64-4.
In Japanese Patent No. 551, inks for crayon and ballpoint pen using benzylidene sorbitols are proposed. In addition, Japanese Examined Patent Publication No. 64-8673 and Japanese Patent Publication No. 1-

０重量％を超えるとゲル強度が低下するためである。In the present invention, two kinds of mixed solvents are used as the organic solvent. That is, the mixed solvent contains at least one of an aliphatic lower alcohol as a main solvent and an aprotic polar solvent as an auxiliary solvent. The aliphatic lower alcohol, which is the main solvent of the mixed solvent of the present invention, has a relatively low boiling point and a high vapor pressure, and can impart quick-drying properties to a solid material. On the other hand, the aprotic polar solvent as the auxiliary solvent has high solubility of the benzylidene sorbitols as the above gel component, and a high-strength gel can be easily obtained.
It is difficult to form a high-strength gel due to its solubility, boiling point, etc. only with the main solvent, and the drying property is low and the inconvenience after writing cannot be solved only with the auxiliary solvent. As the organic solvent in the present invention, two kinds of different solvents are used as described above, and by the synergistic effect of both, a solid substance having an appropriate strength can be obtained, and at the same time, the obtained solid substance can be quickly dried by a solid writing instrument. And it can give the smooth writing feeling and delicate drawing of liquid writing instruments. The aliphatic lower alcohol constituting the main solvent of the present invention is preferably a C 1 -C 3 aliphatic alcohol, and is methanol, ethanol, propanol or isopropanol, and one or more of these can be used. Of these, due to problems such as toxicity and vapor pressure,
It is particularly preferable to use ethanol. The amount of this main solvent in the solid material is 30 to 90% by weight based on the total amount of all components.
And preferably 50 to 70% by weight. 30% by weight
If it is less than 90% by weight, the feeling of writing is heavy and the drawn line becomes rough, and if it exceeds 90% by weight, the solid writing instrument becomes poor in strength and density. Further, the aprotic polar solvent constituting the auxiliary solvent of the present invention is N-methyl-2-pyrrolidone, dimethyl sulfoxide, ethylene carbonate, propylene carbonate, 1,3-dimethyl-2-imidazolidinone, etc. One or two or more of the above can be arbitrarily selected. The compounding amount of this auxiliary solvent in the solid matter is
It is 1 to 30% by weight, preferably 3 to 20% by weight, based on the total amount of all components. If it is less than 1% by weight, its performance is not exhibited and 3
This is because if it exceeds 0% by weight, the gel strength decreases.

とができる。In the present invention, in addition to the gelling component and the organic solvent component described above, a predetermined resin component and a coloring component can be further added to form a solid writing instrument according to a desired use, shape and the like. Known pigments and dyes can be used as the coloring component. The blending amount varies depending on the type of pigment or dye, but is preferably 50% by weight or less with respect to the total amount of the solid components. This is to make the gel formation smoothly. Usually, 5 to 40% by weight is added. Further, as the resin component, vinyl resins, cellulose resins, phenol resins, ketone resins and other resins generally added to writing instruments,
It is preferable to add 1 or 2 or more of those soluble in the main solvent. The content of the resin component is preferably 40% by weight or less, and usually 10 to 40% by weight, based on the total amount of the components of the solid material. This is to obtain good strength and adhesion.
In addition to the above components, the solid writing instrument of the present invention may contain a gelling aid, a film-forming agent, a viscosity adjusting agent, an evaporation inhibitor, an extender and the like added to ordinary writing instruments such as lubricants. . In the present invention, the above-mentioned respective components are mixed, heated and dissolved, and then cooled in a predetermined container to be gelled to obtain a solid substance. The solid material can be changed in hardness by adjusting the gelation rate, and the solid material can be used as a solid writing instrument without changing the strength of the obtained solid material or in a container with a predetermined cap. can do.
