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: Made of three (acryloyloxyethyl) amine (acrylate a)

[0105]After connecting the drip funnel and the condenser with 1L round bottom flask, it is replaced with a nitrogen atmosphere, and the tetrahydrofuran is injected with 200 ml, so that three (hydroxy ethanol) amine (TCI) 25.0 g (0.17 mol) and 2,6-dimethyl Cool to -5 ° C after dissolving 71.8 g (0.67 mol) 71.8 g (0.67 mol). Acryloyl chloride (TCI) 50.0 g (0.55 mol) was dissolved in tetrahydrofuran 150ml, and the drip funnel was placed while preventing temperature from being slowly added after 2 hours. After the drop is completed, the temperature rises to Almost temperature and stirred for 1 hour. Then, the reactants were heated at 65 ° C, and the mixture was further stirred at a reflux condition of tetrahydrofuran for 6 hours. After completion of the reaction, the reactants were again cooled to -5 ° C, and after the aqueous solution of sodium bicarbonate was added, the organic layer was extracted with ethyl...

[0134]Production Example 2: Manufacture of Curing Film

[0135]InThe thickness of the glass substrate (EAGLE 2000; Corning Co., Ltd. manufactured), a Silicon Nitride, is applied to the film, using a spin coater to solidify the film. Coating is carried out in a manner having a thickness of 3.0 μm. After spin coating, it was placed on the platform for 5 minutes, and it was placed in an acrylic box. After replacing a nitrogen atmosphere, the UV curing device (model: LZ-UVC-F402-CMD) was used to illuminate 150MW / cm2(UV-A region measurement) irradiated 20 seconds to obtain a cured coating film.
