FIG. 13 is a longitudinal sectional view showing a state immediately after ink dispensing in the method for producing a penetration mark according to the present invention. The inks 15a to 15c immediately after dispensing are filled in the filling port 1a under the influence of the surface tension where the area divided by the filling port 11a is relatively narrow.
The ink tends to be unbalanced on the wall surface of 1a, and tends to gather at the central portion instead of the entire area where the area divided by the filling port 11a is relatively wide. However, in a state where the inks 15a to 15c penetrate to the diffusion sheet 12, the inks 15a to 15c
Is diffused by the capillary action in the diffusion sheet 12 and penetrates into the stamp material 13. The region obtained by the diffusion by the capillary action is formed by pressing the filling member 11 against the stamp material 13 or by making the diffusion sheet 12 and the filling member By adhering and welding the contact points with the fiber 11, the fibers or the porous structure are uniformly diffused to a place where the fiber or the porous structure is closed or slightly closed.

The arrangement is the same as the area divided by a, and a plurality of types of inks 15a to 15c can be filled into one stamping material 13 in a desired arrangement. In addition, by selecting a member so that the capillary force of the diffusion sheet 12 is weaker than the capillary force of the stamp 13, the ink permeates from the diffusion sheet 12 to the stamp 13 smoothly, and It is possible to reduce the residual amount of ink and shorten the permeation time.

The ink used in the present invention may be either a pigment or a dye as a coloring material. However, in the case where long-term color mixing of a plurality of types of ink filled in a manufactured stamp is to be suppressed. It is preferable to use a pigment as a main component, and the dye is preferably added as a complementary color. However, when the emphasis is not placed on the effect of suppressing color mixing, the dye can be used alone. In the present invention, as the pigment and the dye used as the ink, it is possible to use the pigment and the dye usually used for a writing instrument. In the present invention, the same vehicle is used even when a plurality of types of inks are used.

As the pigment, inorganic or organic pigments such as titanium oxide, carbon black, phthalocyanine, azo, anthraquinone and quinacridone may be used as they are, or those pigments may be used as resins or surfactants. A processed pigment whose surface has been modified by, for example, may be used.

The dye may be a basic dye, an acid dye, a direct dye, or a solubilized or microencapsulated dye. For example, “Varifast Black # 1802” manufactured by Orient Chemical Co., Ltd.
"Varifast Black # 1805", "Varifast Black # 3820", "Varifast Violet #
1701, "Varifast Yellow AUM", and "Varifast Yellow # 3104", "Spiron Violet C-RH", "Spiron Black CMHspecial", and "Spiron Yellow C-GNH" manufactured by Hodogaya Chemical Co., Ltd. , "Spiron Orange GRH", "Spiron Red BEH", auramine, rhodamine, and the like.

The amount of the ink added is not particularly limited, and may be an amount depending on the solubility or dispersing power of the ink or an amount suitable for a desired hue or density. However, this amount is deeply related to the imprint density and the ink ejection amount. If the addition amount is too large, the imprint density increases, but the ejection amount decreases and the life of the penetrating mark is shortened. Conversely, if the amount of addition is small, the life of the seal is prolonged, but the color development of the imprint is not good. Normally,
The range is preferably 3 to 20% by weight based on the total amount of the ink.

The vehicle used to prepare the ink is composed of one dispersion resin and one or more solvents. Here, as the dispersion resin, a polyvinyl butyral resin or an ethyl cellulose resin can be adopted. Examples of the solvent include glycols such as octylene glycol, polyalkylene glycols such as polyethylene glycol and polypropylene glycol, glycol ethers such as diethylene glycol monobutyl ether, and fatty acid esters such as ethylene glycol monoricinoleate and propylene glycol monoricinoleate. , Fatty acid methyl ester of castor oil, polyoxyethylene glycol monoether oleate, polyoxypropylene glycol monoether, and the like can be used. If necessary, components other than those described above, for example, a resin, a surfactant, a preservative, and a dispersing aid may be appropriately added.

In the present invention, the solvent constituting the vehicle is 0.1 mmH from the viewpoint of volatility at room temperature.
It preferably has a vapor pressure of not more than g / 25 ° C., thereby exhibiting good printing performance. The viscosity of the ink mixture comprising the vehicle and the ink is 30 to 2
500 mPa. It is desirable to be within the range of s for the following reason. That is, the ink mixture having a viscosity within the above range shows good results in the printing body holding performance and the ink non-mixability. When it is lower than the above range, the ink filling time is fast, but the ink ejection amount at the time of stamping is large, and the bleeding of the imprint becomes large, so that a clear imprint cannot be obtained. Also,
If it is higher than the above range, it becomes difficult to fill the ink, the ink follow-up property at the time of continuous printing becomes poor, and the tack becomes large at the time of printing, and the ink stringing phenomenon occurs.

Examples of the material used for the stamping material having a continuous porous structure according to the present invention include sponge rubber having a porosity of 30 to 80% and a spring hardness of 20 to 65. As the sponge rubber, acrylic rubber, nitrile rubber, butyl rubber, acrylonitrile / butadiene rubber, ethylene / propylene rubber, ethylene / butylene rubber, vinyl chloride rubber, EPDM (ethylene / propylene / diene copolymer) and the like can be used.
