Embodiment

[0404] The present invention will be described in more detail below using examples, but the present invention is not limited to these examples. In addition, Examples 1-10, 14-23 are examples, and Examples 11-13, 24-26 are comparative examples. In addition, in the following description, unless otherwise specified, "part" and "%" mean "part by mass" and "% by mass", respectively.

[0405] Each measurement was performed by the following method.

[0406] (number average molecular weight (Mn) and weight average molecular weight (Mw))

[0407] Using a commercially available GPC measuring device (manufactured by Tosoh Corporation, device name: HLC-8320GPC), the coagulation of various monodisperse polystyrene polymers with different degrees of polymerization commercially available as a standard sample for molecular weight measurement was measured. Gel Permeation Chromatography (GPC). A calibration curve was prepared based on the relationship between molecular weight of polystyrene ...

[0444] Compound (a11) (in compound (a1), R 1 and R 2 is methyl, R 41 , R 51 , R 71 , R 81 is a hydrogen atom, R 61 A compound having a structure shown in formula (a1-1), X being an oxygen atom, n being 1, and m being 1; manufactured by Ciba Specialty Chemicals Company, trade name: IRGACURE 2959) 2.5 g and triethylamine 2.3 g in dichloro 62 mL of methane was mixed and dissolved to obtain a solution. A solution obtained by dissolving 1.2 g of methacryloyl chloride (compound (b11)) in 8 mL of dichloromethane was added dropwise to this solution while stirring the solution at 0°C. After the dropwise addition, stirred at 0° C. for 1 hour to obtain compound (c11) (in compound (c1), R 1 and R 2 is methyl, R 42 , R 52 , R 72 , R 82 is a hydrogen atom, R 62 A solution of a compound having a structure represented by formula (c1-1), X being an oxygen atom, n being 1, m being 1, and Z being a methacryloy...

[0454] (Production Example 2: Production of Lyophobic Compound (A1-2))

[0455] In 2.4g of 2-butanone, compound (m1-1) 0.90g, 2-hydroxyethyl methacrylate 0.03g and styrene 0.08g in n-dodecyl mercaptan 0.035g and 2,2'- The reaction was carried out at 50° C. for 24 hours in the presence of 0.005 g of azobis(2,4-dimethylvaleronitrile). After cooling to room temperature (20-25°C), add 0.03g of 2-acryloyloxyethyl isocyanate, 0.0001g of dibutyltin dilaurate and 0.0017g of 2,6-di-tert-butyl-p-cresol. Down reaction 24 hours, obtain the 2-butane of the lyophobic property compound (A1-2) that has following formula unit (u1-1-1), unit (u1-2-1) and unit (u1-3-2) Ketone solution. The 2-butanone solution of the obtained lyophobic compound (A1-2) was dropped into hexane to precipitate, and the obtained solid was vacuum-dried to obtain a powdery lyophobic compound (A1-2 ) 0.44g.

Abstract

To provide a curable composition capable of forming or repairing a partition wall with good ink repellency on the upper surface and good ink affinity on the side surface by applying a micro-spraying method, a partition wall formed or repaired using the composition, and a partition wall using this composition A method for producing or repairing a partition wall of the composition, and an optical element including such a partition wall. Curable composition for partition walls of organic EL elements and the like, partition walls formed or repaired using the composition, methods of manufacturing or repairing partition walls using the composition, and organic EL elements having the partition walls, etc. In an optical element, the curable composition for a partition wall is a curable composition for forming a partition wall or repairing a defect generated in a partition wall formed to partition a substrate surface into a plurality of dot-forming The partition shape has an upper surface and side surfaces connected thereto, the curable composition for a partition contains a lyophobic compound (A), a crosslinking agent (B) and a polymerization initiator (C), and the lyophobic compound It is a substance that becomes lyophilic by light irradiation.

Description

technical field [0001] The present invention relates to a curable composition for a partition, a partition, a method for producing a partition, a method for repairing a partition, a repaired partition, and an optical element. Background technique [0002] Recently, in the manufacture of optical components such as organic EL (Electro-Luminescence) components, quantum dot displays, TFT (Thin Film Transistor; Thin Film Transistor) arrays, and thin-film solar cells, organic layers such as light-emitting layers are gradually used as dots. A method of pattern printing by the ink (IJ) method. The inkjet (IJ) method has advantages such as that it is a printing method that does not use a plate, can reduce the cost for making a plate, and can also reduce material costs by using a necessary amount of material only in necessary parts. [0003] In this method, it is necessary to provide partition walls along the outline of dots to be formed. Forming a desired pattern by providing a par...
