- talons having a colorant, an organic solvent, a resin, and a gelling agent as main components are well known.
- dibenzylidene sorbitol, tribenzylidene sorbitol or a derivative thereof, a gelling agent, a resin component, and a colorant are dissolved or dispersed in an organic solvent, and then cooled and solidified.
- Tarayon is known (see Patent Document 1).
- the gelling agent when producing talyon using a benzylidene sorbitol-based compound as described above as a gelling agent, the gelling agent is heated and gelled in an organic solvent in which a resin component is dispersed and dissolved.
- the raw material solution obtained by dissolving the agent is poured into a molding vessel, cooled and solidified to obtain a talon of the required shape.
- the viscosity of the raw material solution is too high, Since it is difficult to inject the solution into the molding container, it is necessary to use a resin having a relatively low molecular weight as the resin component, including the case of using the polyvinyl propylar resin. I helped.
- a low molecular weight component is used as the resin component, the obtained talon is inferior in writing because it has a low gel hardness and easily breaks upon writing.

- At least one selected from the group consisting of mononobutinoate and dipropylene glycol monomethyl ether is preferably used.
- the amount of the organic solvent in the talon is usually 20 to 80% by weight, preferably 30 based on the weight of the force talon appropriately determined in relation to components such as a colorant. 65 is in the range of weight 0/0. If the amount of the organic solvent is too large, it may be difficult to gel the required components together at the time of the production of the crane. On the other hand, if the amount of organic solvent is too small, it will be difficult to dissolve the required components in the production of talon, and a uniform gel may not be formed.

- the above exemplified gelling agents may be used alone or in combination of two or more.
- the content of the gelling agent is usually in the range of 2 to 20% by weight, preferably in the range of 3 to 10% by weight, based on the weight of the talon.
- the gelling agent is too much, the gel hardness of the talon to be obtained is too high, and the colorability and the like deteriorates at the time of writing.
- the gelling agent is too small, In the production of talon, it becomes difficult to gel each component together.
- the taleon according to the present invention contains a colorant, and thereby, handwriting of various colors can be formed on the writing surface.
- a dye is also used as the colorant, but a pigment is preferably used.
- a pigment may be an organic pigment or an inorganic pigment.
- pigments that can be used include phthalocyanine pigments such as copper phthalocyanine blue, selenium, azo, quinacridone, anthraquinone, dioxazine, indigo, thioindigo, perinone, perylene, indolenone, and azoazomethine.
- titanium oxide contains carbon black.
- inorganic pigments such as iron oxide, petal, acid chrome, calcium carbonate, clay, talc, etc., fluorescent pigments, colored wax particles, metal powder pigments such as aluminum powder, So-called pearl pigments are also used.
- Various extender pigments are also used as necessary.
- the colorant that can be used in the present invention is not limited thereto.
- the amount of the colorant in the talon is usually in the range of 2 to 50% by weight, based on the weight of the talon. If the amount of colorant in the talon is less than 2% by weight, the talon obtained will not have sufficient color development. However, when the amount of the colorant exceeds 50% by weight, the relative proportion of the other components other than the colorant is too low in the resulting talon, so that the roles to be played by each cannot be fully demonstrated. I can't get a good taleon. Further, when producing talon, the viscosity of the raw material solution described above is too high, making it difficult to inject it into a molding container. The optimum amount of colorant in a taléon is somewhat different depending on the type of colorant, usually in the range of 3-40% by weight. It is a circle.
- the rosin component is generally formed when writing on the writing surface with the obtained talon and plays the role of putting the components together in the production of talon.
- a resin component a combination of a film-forming resin and an adhesive resin is preferably used, but if necessary, a film-forming resin may be used alone.
- the film-forming resin is specifically for increasing the hardness of the talon and for strengthening the handwriting formed on the writing surface.
- polyvinyl butyral resin has excellent pigment dispersibility, and is used to impart moderate hardness and desirable writing quality to the obtained talon.
- the average degree of polymerization is used.
- a combination of less than 350 polybutyral resin and an average degree of polymerization of 350 or more polyvinyl butyral resin is used.
- the proportion of polybutyral resin having an average degree of polymerization of less than 350 is usually in the range of 20-95% by weight, preferably 40-80% by weight, most preferably 50-75%.
- the proportion of polybutyral resin having an average degree of polymerization of 350 or more is usually 5 to 80% by weight, preferably 20 to 60% by weight, most preferably 25 to It is in the range of 50% by weight.
- the adhesive resin is specifically for enhancing the adhesion of the handwriting by the taleon to the writing surface, and is not particularly limited as long as it has such properties.
- ketone resin, xylene resin, polyamide resin, acrylic resin, maleic resin, terpene phenol resin, alkylphenol resin, etc. are used.
- rosin esters and hydrogenated rosin esters are used in the same manner as adhesive resin.

- acrylic resin examples include thermoplastic polyacrylic acid esters. These adhesive resins can be used alone or in combination of two or more.
- the ratio of the film-forming resin and the adhesive resin is related to other components. Force determined appropriately Usually, the weight ratio of film-forming resin: resin-forming resin film forming resin is about 1: 0.1 to 5, preferably about 1: 0.2 to 3.
- the content of the film-forming resin and the adhesive resin is usually in the range of 3 to 40% by weight, preferably 6 to 35 in terms of the total amount of both. It is in the range of% by weight.
- the ratio of rosin is too high, the gel hardness of the resulting talon is too high, and the colorability and writing quality are poor.
- the ratio of rosin is too small, the components are combined into a gel. And the obtained talon does not have sufficient fixability and strength.
- the talon according to the present invention includes various antifungal agents, fillers, leveling agents, viscosity modifiers, structural viscosity imparting agents, drying property imparting agents, and the like as necessary. Conventionally, it is known as an additive in taleon, and may contain any appropriate ones. It also contains plasticizers such as jetyl phthalate, dibutyl phthalate, dioctyl phthalate, epoxyhexahydro 2-ethylhexyl phthalate, 2-ethylhexyl sebacate, tricresyl phosphate as appropriate. .
- Te Contact ⁇ the present invention the gel hardness of Tareyon, the organic solvent used, a gelling agent, the force due to kind and amount of such ⁇ usually, 5 ⁇ 50KgZcm 2 mm, preferably, 7 ⁇ 30KgZcm 2 This is the range.
- the components according to the present invention can be obtained by uniformly mixing the above-described components and gelling them together. For example, for example, a combination of the polybutyl butyral resin is added to an organic solvent and dissolved, and a colorant is added to the resulting solution. After sufficiently dispersing, if necessary, a gelling agent is added thereto under heating, and these are dissolved and dispersed. Finally, the uniform raw material solution thus obtained has a desired shape. If it is poured into a forming container, cooled, and solidified, a talon having such a shape can be obtained.
