親油性物質が表面に存在しない。(Prior art) Silicone rubber transfer bodies (especially RTV type) can be cured at low temperatures below 40°C, the rubber hardness can be freely changed over a wide hardness range from 1° to 80°, and it has extremely high Condensation silicone rubber is increasingly being used as a transfer material due to its solvent resistance, but its surface is covered with a non-oleophilic low molecular weight component, making it difficult for ink to adhere to it. If this is insufficient, in order to improve the wettability of the surface to the ink, the non-oleophilic low molecular weight components on the rubber surface can be removed by performing several dozen run-in printings or by performing an appropriate surface treatment. By the way, since addition type silicone rubber is cured by a radical reaction, there is no non-oleophilic substance present on the surface.

一般的な方法である。For this reason, the ink can be easily transferred from the plate onto the silicone rubber, but since the affinity between the addition-type silicone rubber surface and the ink is too high, in order to transfer from the addition-type silicone oil to the subject, it is necessary to A common method is to disperse and use silicone oil of about 100 centipoise.

) The method of adding silicone gel is described in JP-A-52-4311 (Printing ink transfer material and its manufacturing method). Gel is added, and the hardness is extremely low (less than 1), which improves the transferability of the ink to the transfer body, and the non-reactive silicone oil oozes onto the surface of the transfer body. , the transferability of the ink to the printing material is approximately 100χ.

Since non-reactive silicone oil is added, it gradually leaches onto the rubber surface, forming a non-oleophilic thin film.

転写は不完全であり、はとんど転写しない。For this reason, when condensation type silicone rubber is generally used for printing ink transfer materials, it is necessary to perform several dozen run-in printings or appropriate surface treatment to remove non-oleophilic substances on the surface before use. . For example, ■Patent filed by Hitachi, "Transfer body for transfer method printing" (Japanese Patent Laid-Open No. 50-15
No. 5100), a transfer body that has been cast and hardened is immersed in a gas discharge containing fluorine such as CF for several seconds or more,
The oily low-molecular-weight silicon compound on the surface of the transfer body is removed as fluoride by fluorine radicals generated by electric discharge, or the transfer method is immersed in a mixed acid solution containing chromic acid for several seconds or more to perform transfer 2. A surface treatment method is described that improves the ink transfer properties of a silicone rubber transfer body by decomposing and removing an oily low-molecular-weight silicon compound on the body surface. Indeed, this treatment method provides good ink transfer properties for commercially available oil-based and water-based inks over a wide range of silicone rubber hardness from 1° to 80°, and also improves the solvent resistance and chemical resistance that are characteristic of silicone rubber. without sacrificing sex,
It appears to be an excellent surface treatment method that provides transfer resistance that can withstand almost all solvents and chemicals used in printing. However, the curing caused by these treatments remains on the rubber surface, and non-oleophilic substances remain inside and gradually leach out to the surface.As a result, the shape of the ink transfer from the printing plate to the condensation type silicone rubber changes over time. It changes. Also,
In the case of addition-type silicone rubber, the curing mechanism is a radical addition reaction, so there are no non-oleophilic low molecular weight substances in the cured silicone rubber, and the shape of the ink transfer from the plate is good, but addition-type silicone rubber The transfer of the ink from the ink to the printing medium is incomplete and rarely transfers.

ある。従って付加型シリコーンゴムも縮合型シリコーン
ゴムと同様な現象が起るため、版から付加型シリコーン
ゴムへのインキの転移形状も経時的に変化する。Therefore, it is generally necessary to add about 20 to 30% by weight of a non-reactive silicone oil having a viscosity of about 30 to 100 centipoise to increase the ink releasability and transferability. Therefore, the same phenomenon as that of condensation type silicone rubber occurs with addition type silicone rubber, and the shape of the transfer of ink from the printing plate to addition type silicone rubber also changes over time.

It is a printing ink transfer body.

を添加する必要がない。By adding an addition silicone gel in which one of the inert terminal groups of a non-reactive silicone oil is replaced with an active group to an addition silicone rubber that does not contain a non-oleophilic substance, appropriate ink releasability can be achieved. Apply the mold to the silicone rubber surface. Further, the rubber structure to which the addition-type silicone gel is added has a dense structure, and requires no or a small amount of a rubber reinforcing filler such as silica powder, and there is no need to add non-reactive silicone oil.

５０°（ＪＩＳ Ｃ）が得られる。Addition-type silicone rubber originally has good affinity with ink, so it lacks transferability to the printing medium. It is possible to balance the ink transferability to the mold silicone rubber and the ink transferability from the addition type silicone rubber to the printing substrate, and if the concentration of the non-oleophilic substance on the rubber surface does not change, it is possible to transfer the ink from the plate to the addition type silicone rubber. Neither the shape of the transfer of ink to the silicone rubber nor the shape of the transfer from the additive type silicone rubber to the printing material changes over time. Therefore, as non-lipophilic substances, non-reactive silicone oils such as dimethylpolysiloxane, methylphenylpolysiloxane, and hydroxymethylpolysiloxane are used, with one of the inert end groups substituted with an active group such as a vinyl group or an aquatic group. , by using addition-type silicone gel,
After the silicone rubber is cured, the addition-type silicone gel is also incorporated into the structure of the addition-type silicone rubber, making it impossible for the gel to migrate from the interior to the surface. The concentration of silicone gel does not change. The appropriate amount of addition type silicone gel added is 15 to 30% by weight, and when using addition type silicone rubber with a rubber hardness of 65° (JIS C), the rubber hardness is 57° to 57°.
50° (JIS C) is obtained.

刷ができる。Furthermore, by using a rubber with a rubber hardness of about 20° (JIS C), which is even lower in hardness, singly or in combination, an addition-type silicone rubber with a rubber hardness of 57° to 10° (JIS C) can be obtained, and the film thickness can be reduced. It can also be used for thick film printing of about 5 μM. The addition-type silicone rubber printing ink □ transfer body obtained in this way does not require any leveling printing or surface treatment before use, and there is no change over time in the transferability of the ink during printing. Stable printing is possible until a physical change occurs on the surface.

Printing was performed on a glass substrate using test plates with various combinations of patterns of mm+ and plate depth of 0.01-1. At this time, in the transfer material created without adding silicone gel, most of the pattern remained on the rubber and was not transferred onto the glass substrate, whereas in the above transfer material with silicone gel added, the pattern was completely transferred to the glass substrate. Transfer was performed on the substrate, and no deterioration of the transferred shape was observed even after continuous printing.

For this reason, there is no need to add unstable silicone oil to the silicone rubber, and therefore there is no surface change over time such as silicone oil seeping onto the rubber surface, and stable printing is maintained until physical deterioration of the surface occurs. can be done. In addition, compared to condensation type silicone rubber, addition type silicone rubber has a smaller amount of reinforcing filler added inside, and there is no protrusion on the rubber surface due to aggregation of these fillers, so it can be used for shallow concave plates. (For example, 5
Even when a diameter of 7 μm is used, there are very few pinholes. Furthermore, since the additive silicone rubber has a high affinity with ink, the printing pressure can be lowered and the dimensional accuracy of the printed pattern has also been improved.
