Formation of Polyimine Film Using Inkjet Ink (1) and Evaluation of Flexibility (1) Formation of Inkjet Printed Linear Polyimine Film Using Inkjet Prepared in Example 1 Ink (丨) for water, using the black spray coating manufactured by FUJIFILM Dimatix Co., Ltd., 2·&quot; DMP-fine, in thick glass epoxy resin:: 1 point width set point spacing (dotpitch) is 4〇 , from the board, to apply a line length of 5 cm. The ink jet 2 设定 was set to 30 〇 C, the piezoelectric (piezo) voltage i heater was blown at 16 V, and the drive 81 200918615 dynamic frequency was set to 5 kHz. Then, the substrate was heated in a brewing box for 2 minutes after the thief's heating plate for 2 minutes to obtain a polyimide film formed into a linear shape. An optical microscope was used to observe the uniformity of the line width and the line width of the obtained polyimide film, and the polarization was changed. Turning to (4) The stylus type film thickness meter a_STEP2GQ manufactured by KLA_Te_r japan Co., Ltd., the average value (four) of the three measured values. The film thickness of the obtained ageing ship and a uniform film having a line width of 1.25 // m and 12 分别, respectively, were obtained. (2) Flexibility (polyester resistance) of the polyimide film The inkjet ink (1) synthesized in Example 涂布 was applied to a substrate (DUPONT_TORAY Co., Ltd.) using an applicator (applicator) Made of Kapton 200H (thickness 5 〇 #m)). Subsequently, it was dried at 50 ° C for 30 minutes using a hot plate, and then heated in a 230 T: oven for 30 minutes to form a film on one side of the substrate. Then, the TD Fangtiandian (transverse direction) of the substrate was cut into a length of 15 cm and a length of 13 cm to form a test specimen. &lt; Using a folding endurance tester (manufactured by Toyo Seiki Seisakusho Co., Ltd.) MIT-D A 'Set the radius of curvature of the curved surface (curvature) to 0.38 mm, the bending angle to 135°, and the tension to 4 9N The test specimen was bent at a speed of i75 times per minute, and cracks were observed when the bending was repeated a certain number of times. As a result, no crack was generated when the number of times of bending was 1000, and it was evaluated as ◎. The results of the bendability were evaluated in the following manner. 82 200918615 No cracks were observed. When cracks were observed, no cracks were observed, but when cracking ι_ times, $ splits were observed. ^^(4) No cracks were formed, but 5 g was bent. In the case of the inkjet ink which was bent to be equal to or greater than 〇, the bending property was judged to be good.

The result is Miscellaneous 3. [Comparative Example 3] Evaluation of the compatibility of the polyimide film using the inkjet ink (E1) 1) Formation of a linear polyimide film by inkjet printing except that the synthesis was carried out in Comparative Example 1. An insulating polyimide film formed into a linear shape was obtained under the same conditions as in Example 4 except that the inkjet ink (E1) was used as the inkjet ink. The obtained polyimide film was evaluated under the same conditions as in Example 4. As a result, the polyimine film has a line width of 230, which is wider than that obtained when coating 83 200918615. The resulting film of the hybrid yam has a uniform film. J βτη (2) Flexibility of the polyimine film (folding resistance) The inkjet ink (Ε1) synthesized in Comparative Example 1 was used to produce a folding resistance test under the same conditions as in Example 4. kind. The test sample was observed under the same conditions as in Example 4, and the crack was obtained when the bending was repeated for a certain number of times. The result was that the number of f-foldings was not cracked, but cracks were observed in the bending cut. Its evaluation is △. Eight. [Comparative Example 4] Formation and Characterization of Polyimine Film Using Inkjet Ink (E2) (1) Formation of Linear Polyimine Film Printed by Mouth Ink except for Use in Comparative Example 2 A linear insulating polyimide film was formed under the same conditions as in Example 4 except for the synthetic inkjet ink 7 (£2). As a result, since the inkjet ink is a component having a high molecular weight component as a main component, stringiness is caused by elongation of the polymer chain, and the formation of ink droplets is too large to cause a large bokeh. A uniform polyimine oxime is formed. (2) Flexibility (Folding Resistance) of the Polyimide Film A non-folding test sample was produced under the same conditions as in Example 4 except that the inkjet ink (E2) synthesized in Comparative Example 2 was used. The test samples were bent under the same conditions as in Example 4, and the cracks were observed when the bending was performed for a certain number of times. As a result, cracks were not generated when the number of bending times was 1〇〇〇84 200918615.
