Embodiment

[0401] 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 1-9 and Examples 11-19 are examples, and Examples 10 and 20 are comparative examples.

[0402] Each measurement was performed by the following method.

[0403] [Number average molecular weight (Mn) and mass average molecular weight (Mw)]

[0404] Using a commercially available GPC measuring device (manufactured by Tosoh Corporation, device name: HLC-8320GPC), as a standard sample for molecular weight measurement, commercially available multiple monodisperse polystyrene polymers with different degrees of polymerization were measured for coagulation. Gel Permeation Chromatography (GPC). A standard curve was prepared based on the relationship between the molecular weight of polystyrene and the retention time.

[0405]After each sample was diluted to 1.0% by mass with tetrahydrofuran and passed through a 0.5...

example 1

[0442] [Example 1: Preparation of ink repellent agent (C1) liquid]

[0443] At 1,000cm equipped with a mixer 3 32.3 g of the compound (c-11) and 67.7 g of the compound (c-21) were charged in a three-necked flask of the same, to obtain a hydrolyzable silane compound mixture. Next, 569.4 g of PGME was added to this mixture to prepare a raw material solution.

[0444] 44.7 g of 0.1 mass % hydrochloric acid aqueous solution was dripped at the obtained raw material solution. After completion|finish of dripping, it stirred at 40 degreeC for 5 hours, and obtained the PGME solution (ink repellent agent (C1) concentration: 10 mass %) of the ink repellent agent (C1). Hereinafter, this solution is called (C1) liquid.

[0445] In addition, after completion|finish of reaction, the reaction liquid was measured using gas chromatography, and it confirmed that each compound used as a raw material was below the detection limit.

[0446] Table 1 shows the composition (mol %) of the feed amou...

example 2～10

[0447] [Examples 2-10: Preparation of Ink Repellent Agents (C2)-(C9) and (H1) Liquid]

[0448] The feeding amount composition (mol %) and the kind of solvent of the ink repellent are set as shown in Table 1, except that, operate in the same way as Example 1, and obtain the ink repellent (C2)~(C9), and (H1 ) solution (ink repellent agent concentration: 10% by mass). Hereinafter, each solution is called (C2)-(C9), (H1) liquid.

[0449] In addition, in Example 10, the ink repellent agent (H1) liquid was prepared without using a compound (c-2). Since this ink repellent is not the ink repellent (C) of this invention, the sign of the ink repellent was changed. All the ink repellent agents for comparison were made into (H), and the ink repellent agent of Example 10 was made into (H1).

Abstract

Provides a partial hydrolysis condensate of a hydrolyzable silane compound; an ink repellent that can selectively impart good ink repellency to the upper surface of the partition wall; can selectively impart good ink repellency to the upper surface of the partition wall even when exposed at a low exposure amount. Excellent ink repellency, negative photosensitive resin composition that is not easy to leave ink repellent agent in the dot; cured film and partition wall that can maintain ink repellency well even after UV / O3 irradiation treatment; and can be uniform in the dot Optics that coat ink well. A partially hydrolyzed condensate of a mixture comprising a first hydrolyzable silane compound and a second hydrolyzable silane compound, the first hydrolyzable silane compound having a fluoroalkylene group and / or a fluoroalkyl group, and a hydrolyzable group, and does not have a mercapto group, and the second hydrolyzable silane compound has a mercapto group and a hydrolyzable group, and does not have a fluoroalkylene group and a fluoroalkyl group.

Description

technical field [0001] The present invention relates to a partially hydrolyzed condensate, an ink repellent agent using the same, a negative photosensitive resin composition, a cured film, a partition wall, and an optical element. Background technique [0002] For an organic EL (Electro-Luminescence) element, there is a method of pattern-printing an organic layer such as a light-emitting layer by an inkjet (IJ) method. In the aforementioned method, a partition wall is provided along the dot outline, and ink containing a layer-forming material is injected inside it, dried and / or heated, etc., thereby forming a desired pattern film. [0003] In the above method, in order to prevent color mixing of ink between adjacent dots and uniformly coat ink in dots, the upper surface of the partition wall needs to have ink repellency, and the side surface of the partition wall needs to have ink affinity. That is, the upper surface of the partition needs to selectively have ink repellency...
