Problems solved by technology

At this time, if the surface migration of the ink repellent is insufficient, there is a problem that the ink repellency on the side of the partition wall is poor due to the ink repellent remaining inside the film; the surface of the ink repellent migrates when the film surface is dissolved in the developing process The layer is thin and all of it is removed, resulting in poor ink repellency on the surface of the partition wall, etc.
[0008] In addition, after development, since the photosensitive resin composition remains on the dots, there may be blank spots of the ink
In order to prevent this phenomenon, the dots are subjected to ultraviolet / ozone irradiation treatment before ink injection, but there is also a problem that the ink repellency of the partition wall is lowered at this time.

Embodiment

[0526] Hereinafter, the present invention will be described in more detail using examples, but the present invention is not limited to these examples. In addition, Examples 1-6 and Examples 8-13 are examples, and Example 7 and Example 14 are comparative examples.

[0527] Each measurement was performed by the following method.

[0528] [Number average molecular weight (Mn)]

[0529]Using a commercially available GPC measuring device (manufactured by Tosoh Corporation, device name: HLC-8320GPC), the gels of several commercially available monodisperse polystyrene polymers with different degrees of polymerization were measured as standard samples for molecular weight measurement. Permeation chromatography (GPC), according to the relationship between the molecular weight of polystyrene and retention time (retentiontime), a standard curve was made.

[0530] After diluting the sample with tetrahydrofuran to 1.0% by mass and passing it through a 0.5 μm filter, the GPC of the sample...

[0552] [Example 1: Synthesis of ink repellent (C1) and production of (C1) liquid]

[0553] The ink repellent agent (C1) is synthesize|combined by the reaction represented by the formula (71) shown below.

[0554] It should be noted that the product obtained by the reaction shown in formula (71) is a partial hydrolysis condensate with hydrolyzable groups or silanol groups remaining. In this example, the obtained partial hydrolysis condensate is used as ink repellent. Agent (C1) is used. However, it is difficult to represent the product (partially hydrolyzed condensate) with a chemical formula. In formula (71), the average composition formula shown in formula (3-2) assumes that the product (partially hydrolyzed condensate) produced by the reaction shown in formula (71) is partially hydrolyzed The chemical formula when all the hydrolyzable groups or silanol groups in the condensate form siloxane bonds.

[0563] [Example 2: Synthesis of ink repellent (C2) and production of (C2) liquid]

[0564] At 50cm with the stirrer 3 0.5 g of compound (c-11), 0.41 g of compound (c-21), and 1.67 g of compound (c-31) were added to a three-necked flask to obtain a raw material mixture of an ink repellent agent (C2). Next, 9.0 g of PGME was added to this raw material mixture to prepare a solution (raw material solution).

[0565] To the obtained raw material solution, 0.16 g of a 65% by mass nitric acid aqueous solution was added dropwise while stirring at room temperature, and the compound (c-21) in the mixture, namely C 6 h 5 NH(CH 2 ) 3 Si(OCH 3 ) 3 become [C 6 h 5 NH 2 (CH 2 ) 3 Si(OCH 3 ) 3 ] + ·NO 3 - (Process (I)).

[0566] After 5 minutes, 1.44 g of 1.0 mass % nitric acid aqueous solution was further dripped. After the dropwise addition, it was further stirred for 5 hours, and the ink repellent ( C2) (step (II)). In the step (II), the reaction was monitored by gas ch...

Abstract

Provided are a negative-type photosensitive resin composition, and a method for manufacturing an ink-repellent agent which may be applied to the composition, with which a partition wall may be manufactured with a high level of storage stability, and a high level of ink repellency may be maintained even after ultraviolet / ozone irradiation. Also provided are the partition wall which maintains the high level of ink repellency even after the ultraviolet / ozone irradiation, and an optical device comprising the partition wall with which a white spot phenomenon may be prevented. The present invention relates to the negative-type photosensitive resin composition which contains a solvent (D), a photoinitiator (B), an alkali-soluble resin (A), and an ink-repellent agent (C) configured by a partial hydrolysis condensate manufactured by a method which comprises a process in which an acid is included in a mixture containing a hydrolytic silane compound containing a fluorine-containing hydrolyzed silane compound and an amino group to convert a nitrogen atom into a proton, and a process in which water and an acid catalyst are included in the mixture for a hydrolysis and a condensation reaction; the partition wall which is configured by the hard coating film and configured in a shape which divides a substrate surface into a plurality of partitions; and an optical device which comprises the partition wall.

Description

technical field [0001] This invention relates to the manufacturing method of an ink repellent agent, the negative photosensitive resin composition containing the ink repellent agent obtained by the method, the partition using the same, and the optical element which has this partition. Background technique [0002] As an optical element, a method of applying a photosensitive resin composition to a substrate and forming it by photolithography is known as a partition wall used in a pixel portion of a color filter or an organic EL (Electro-Luminescence) element. [0003] In recent years, a cost-reducing process using an inkjet method has been proposed as a method of manufacturing a color filter or a pixel portion of an organic EL. [0004] For example, in the manufacture of a color filter, after forming partitions by photolithography, R (red), G (green), and B (blue) are ejected by inkjet to the openings (dots) surrounded by the partitions. ) ink is applied to form pixels.
