本発明は、シリコーンブランケットの表面の略全面に形成したインキ層を、表面に所定のインキパターンに対応した凹部を有する版の前記表面に接触させて前記凹部以外のインキ層を前記版の表面に転写させることで前記シリコーンブランケットの表面から選択的に除去して、前記シリコーンブランケットの表面に前記凹部に対応したインキパターンを形成したのち、前記インキパターンを被印刷体の表面に印刷する反転印刷法に用いるインキであって、バインダ樹脂、着色剤、および溶剤を含み、前記溶剤が、n−ペンタン、n−ヘキサン、n−へプタン、およびイソプロピルアルコールからなる群より選ばれた少なくとも1種の低張力溶剤を50質量%以下の割合で含有しているとともに、前記低張力溶剤100gに対する23℃での溶解度が10g以下であるフッ素系界面活性剤を、インキの総量中の0.01質量%以上、10質量%以下の割合で含有していることを特徴とするインキである。 In the present invention, an ink layer formed on substantially the entire surface of a silicone blanket is brought into contact with the surface of a plate having a recess corresponding to a predetermined ink pattern on the surface, so that an ink layer other than the recess is formed on the surface of the plate. A reversal printing method in which the ink pattern corresponding to the concave portion is formed on the surface of the silicone blanket after being selectively removed from the surface of the silicone blanket by transferring, and then the ink pattern is printed on the surface of the substrate. Ink used in the method, comprising a binder resin, a colorant, and a solvent, wherein the solvent is at least one kind selected from the group consisting of n-pentane, n-hexane, n-heptane, and isopropyl alcohol. It contains a tension solvent at a ratio of 50% by mass or less, and dissolves at 23 ° C. with respect to 100 g of the low tension solvent. An ink comprising a fluorine-based surfactant having a solubility of 10 g or less in a proportion of 0.01% by mass or more and 10% by mass or less in the total amount of the ink.
本発明のインキは、印刷用ブランケットとしてシリコーンブランケットを用いた反転印刷法に用いるものであって、バインダ樹脂、着色剤、および溶剤を含み、前記溶剤が、n−ペンタン、n−ヘキサン、n−へプタン、およびイソプロピルアルコールからなる群より選ばれた少なくとも1種の低張力溶剤を50質量%以下の割合で含有しているとともに、前記低張力溶剤100gに対する23℃での溶解度が10g以下であるフッ素系界面活性剤を、インキの総量中の0.01質量%以上、10質量%以下の割合で含有することを特徴としている。 The ink of the present invention is used in a reversal printing method using a silicone blanket as a printing blanket, and includes a binder resin, a colorant, and a solvent, and the solvent includes n-pentane, n-hexane, n- It contains at least one low-tension solvent selected from the group consisting of heptane and isopropyl alcohol at a ratio of 50% by mass or less, and has a solubility at 23 ° C. in 100 g of the low-tension solvent of 10 g or less. It is characterized by containing a fluorine-based surfactant in a proportion of 0.01% by mass or more and 10% by mass or less in the total amount of ink.
本発明において、低張力溶剤としては、n−ペンタン(16.0mN/m)、n−ヘキサン(18.4mN/m)、n−へプタン(19.6mN/m)、およびイソプロピルアルコール(20.8mN/m)からなる群より選ばれた少なくとも1種を用いる。なおカッコ内の数値は、温度25℃の環境下、英弘精機(株)製の動的表面張力計シータt60を用いて、最大泡圧法によって測定した、各低張力溶剤の表面張力である。
前記少なくとも1種の低張力溶剤を用いることにより、インキの表面張力を低下させて濡れ性を向上することができる。したがって、シリコーンブランケットの表面の略全面にインキを塗布してインキ層を形成する際にはじき等を生じにくくして、前記はじき等が原因となってインキ層にムラやピンホール等が生じるのを防止できる。
In the present invention, low-tension solvents include n-pentane (16.0 mN / m), n-hexane (18.4 mN / m), n-heptane (19.6 mN / m), and isopropyl alcohol (20. At least one selected from the group consisting of 8 mN / m) is used. The numerical value in parentheses is the surface tension of each low-tensile solvent measured by the maximum bubble pressure method using a dynamic surface tension meter Theta t60 manufactured by Eihiro Seiki Co., Ltd. under an environment of a temperature of 25 ° C.
By using the at least one low-strength solvent, the surface tension of the ink can be reduced to improve the wettability . Therefore, hardly cissing or the like when forming an ink layer by applying the ink on substantially the entire surface of the surface of the silicone blanket, the said cissing like unevenness and pinholes in the ink layer causes there is arising Can be prevented .
また低張力溶剤の含有割合や、あるいは組み合わせる他の溶剤の種類等にもよるが、シリコーンブランケットの表面に対するインキの濡れ性が高くなりすぎるのを防止して、インキパターンを、前記シリコーンブランケットの表面から基板の表面に良好に転写させることができ、転写されたインキパターンの形状に乱れを生じるのを防止できる。 The content and the low tension solvent, or combined depending on the kind of other solvents, to prevent the that too high wettability of the ink to the surface of the silicone blanket, the ink pattern, of the silicone blanket Ki de be satisfactorily transferred from the surface to the surface of the substrate, it is possible to prevent the disturbed in the shape of the transferred ink patterns.
またインキの、スリットダイコータ等に対する濡れ性を抑制して、特にスリットの付近に付着しにくくでき、付着したインキが乾燥してバインダ樹脂等が異物として析出してスリットを部分的に塞ぐことによる、インキ層に縦スジを生じたり、前記縦スジによるインキパターンの乱れを生じたりする問題が生じるのを防止できる。 The ink, by suppressing wettability to a slit die coater or the like, in particular can not easily adhere to the vicinity of the slit, due to closing the slit partially binder resin adhered ink is dried is precipitated as foreign, It is possible to prevent the occurrence of problems such as vertical stripes in the ink layer and disturbance of the ink pattern due to the vertical stripes .
低張力溶剤の含有割合が、溶剤の総量の50質量%以下に限定されるのは、下記の理由による。 The reason why the content ratio of the low- tension solvent is limited to 50% by mass or less of the total amount of the solvent is as follows.
n−Hex:ノルマルヘキサン
S−611:サーフロンS−611
S−651:サーフロンS−651
F−444:メガファックF−444
n-Hex: n-hexane
S -611: Surflon S-611
S-651: Surflon S-651
F-444: Mega Fuck F-444
表1、表2の実施例1〜4、比較例3、4の結果より、低張力溶剤100gに対する溶解度が10g以下である実質的に溶剤不溶性のフッ素系界面活性剤を用いることにより、シリコーンブランケットの表面に対して適度の濡れ性と離型性とを兼ね備え、前記シリコーンブランケットの表面に縦スジやムラ、ピンホール等のない厚みが均一なインキ層を形成するとともに、基板等の被印刷体の表面に厚みが均一なインキパターンを形成でき、しかも安全性の問題等も生じにくい反転印刷法用のインキが得られることが判った。 From the results of Examples 1 to 4 and Comparative Examples 3 and 4 in Tables 1 and 2, a silicone blanket was obtained by using a substantially solvent-insoluble fluorosurfactant having a solubility in 100 g of a low-tension solvent of 10 g or less. It has moderate wettability and releasability with respect to the surface of the silicone blanket, and forms an ink layer with a uniform thickness without vertical stripes, unevenness, pinholes, etc. on the surface of the silicone blanket, and a substrate such as a substrate It was found that an ink for a reversal printing method can be obtained, in which an ink pattern with a uniform thickness can be formed on the surface of the ink, and which is less likely to cause safety problems.
