Problems solved by technology

However, in order to planarize the composition without solvent, it is necessary to design the composition in the direction of reducing the overall viscosity and increasing the fluidity during coating. The ratio of diluents composed of equal components increases, but the concentration of double bonds per unit weight of monofunctional diluent components is low, and the number of substituents in one molecule is small, so it is difficult to form a strong cured structure by forming cross-linking bonds
In order to solve this problem, by increasing the ratio of the multifunctional acrylate component with a large number of substitutions, that is, the crosslinking agent, and increasing the curing speed and crosslinking density, desired mechanical properties can be obtained, but the viscosity of the composition is significantly increased. Satisfactory flattening cannot be achieved at the coating or coating stage, and sometimes the viscosity is too high to be used in inkjet methods, etc.
[0004] On the other hand, Korean Laid-Open Patent No. 10-2016-0049953 describes a photocurable monomer limited to a POC parameter value, but the existing problem of viscosity increase as the functional group of the compound increases has not yet been solved

[0104] Synthesis Example 1: Production of Tris(acryloyloxyethyl)amine (Acrylate A)

[0105] After connecting the dropping funnel and the condenser tube to a 1L round bottom flask, the atmosphere was replaced with nitrogen, and 200 mL of tetrahydrofuran was injected, and 25.0 g (0.17 mol) of tris(hydroxyethanol)amine (manufactured by TCI) and 2,6-dimethyl After dissolving 71.8 g (0.67 mol) of pyridine (manufactured by Sigma-Aldrich), it was cooled to -5°C. A solution obtained by dissolving 50.0 g (0.55 mol) of acryloyl chloride (manufactured by TCI) in 150 mL of tetrahydrofuran was put into a dropping funnel, and slowly added dropwise over 2 hours while preventing a sharp rise in temperature. After the dropwise addition, the temperature was raised to At room temperature and stirred for 1 hour. Then, the reactant was heated at 65° C. and further stirred for 6 hours under the reflux condition of tetrahydrofuran. After the reaction was completed, the reactant was cooled to -5°C ...
