Definitions
- the present invention relates to a method for producing a flexographic printing plate and a flexographic printing plate.
- a general photosensitive resin plate for flexographic printing is produced through exposure / development and post-exposure steps as described in Patent Documents 1 to 3, for example.
- the printing method using the photosensitive resin plate for flexographic printing is to supply ink to the convex surface of the uneven resin plate with an ink supply roll or the like, and then contact the resin plate with the substrate to be printed. In this method, the ink on the surface is transferred to the substrate.
- ink often adheres to the shoulder portion of the convex portion of the resin plate or ink enters the concave portion (hereinafter referred to as plate surface contamination) often occurs during printing over a long period of time. As a result, a portion that is not an original pattern may be printed, resulting in a decrease in print quality.
- flexographic printing has been applied to high-definition printing, and halftone printing with a high number of lines is actively performed in order to produce gradations of color and density.
- the interval between the halftone dots becomes smaller, the ink is more likely to be clogged between the halftone dots of the printing plate. If the ink accumulates above a certain level in the valleys of the printing plate, these transfer to the substrate and cause dot entanglement, resulting in a significant reduction in print quality.
- flexographic printing is one of the features that can be applied to various types of inks such as water-based ink, alcohol-based ink, solvent-based ink, and UV ink.
- inks such as water-based ink, alcohol-based ink, solvent-based ink, and UV ink.

This method includes silicon in the resin composition, and exhibits an excellent sustained effect as compared with a method in which a silicone solution is brought into contact with the plate surface.
- the organosilicon compound is distributed throughout the printing plate composition, and the amount of silicone present on the printing plate surface is small. For this reason, it cannot be said that the essential ink clogging prevention effect is sufficient.
- the adhesiveness of a resin layer and a base film may be reduced, and a serious defect that the base film and the resin layer are peeled off during printing may occur.

表面張力は、ぬれ張力試験用混合液(関東化学株式会社製)を用いて評価を行った。20℃、60RH%の雰囲気下で、22.6mN/m、25.4mN/m、27.3mN/m、30mN/m,31mN/m,32mN/m、33mN/m、34mN/m、35mN/m、36mN/m、37mN/m,38mN/m,39mN/m、40mN/mの各ぬれ張力試験用混合液を印刷版上に2滴たらし、綿棒で塗り広げた時の液の濡れ広がり方を目視で評価した。液がはじいた混合液の数値を表面張力とした。表面張力が低いほど、インクをはじく性質が高く、印刷時のインク詰りを防ぐ効果が高い。
インキ絡みは、フレキソ印刷機FPR302(エム・シーケー社製)を用い、800LPIのアニロックスを用いて行った。インキは溶剤インキ(商品名:ブライトフレックス(DIC株式会社製))を用いて行った。被印刷体にはコート紙(商品名:パールコート 王子製紙製)を用いた。印刷速度は50m/分で行った。上記条件で、まず50m印刷を行い印刷サンプルを採取した。引き続き950m印刷を行い、合計1000m印刷した後のサンプルを得た。評価する網点は、125,150,175,200LPIで1,5,10,20%の網点でインキ絡みを評価した。インキ絡みが皆無の場合“A”、インキ絡みが網点最端部のみできた場合“B”、インキ絡みが網点端部付近で発生した場合“C”、インキ絡みが網点全面に発生した場合“D”とした。
