Embodiment approach

[0077] According to an exemplary embodiment of the present invention, a functional group capable of imparting hydrophobicity may be introduced into such a cardo-based compound. In particular, as described above, fluorine may be introduced.

[0078] In the preparation of the cardo-based compound, introduction of fluorine and examples of compounds usable in the introduction of such a group are not limited. Specifically, it is a compound obtained by the following reaction formula 1.

[0079] Reaction 1

[0080]

[0081] Equation 1 illustrates the introduction of fluorine into a cardo-based compound and should not be construed as limiting the fluorine-containing cardo-based compounds useful in the present invention.

[0082] The cardo-based compound may be used in an amount of about 1 to 40 wt%, and preferably in an amount of about 20 to 30 wt%, based on the total solid weight of the photopolymerizable resin composition. When a fluorine-containing compound is used as the car...

[0105] The components shown in Table 1 below were charged into a 1000 ml four-necked flask, and stirred for 30 minutes while blowing nitrogen gas. Then, the temperature was gradually raised, and the reaction was carried out at 70° C. for 6 hours, then the temperature was raised to 80° C., and the reaction was carried out for another 2 hours, whereby an alkali-soluble acrylic binder resin was synthesized. In Table 1 below, units are expressed in g.

[0115] Preparation Example 6: Synthesis of Cardo-Based Compounds

[0116] 58g bisphenol fluorene type epoxy resin (epoxy equivalent 232), 313g PGMEA, 2.5g triethyl benzyl ammonium chloride, 0.03g hydroquinone and 18g acrylic acid join in the four-necked flask of 500ml, at 25ml / While passing nitrogen gas at a rate of min, heat to 80-90°C and dissolve. The slightly opaque solution was gradually heated and then completely dissolved at 80°C. Continue heating and stirring until the measured acid value of the solution is less than 1.0 mgKOH / g. In this regard, it takes 12 hours to achieve the desired acid number. The above solution was cooled to room temperature to obtain a colorless and transparent bisphenol fluorene type epoxy acrylate.

[0117] 300g of the bisphenol fluorene type epoxy acrylate thus obtained and 14g of 1,2,3,6-tetrahydrophthalic anhydride, 0.3g of 3,3',4,4'-biphenyltetracarboxylic dianhydride and 0.76 g of tetraethylammonium bromide was mixed, and then the re...

Abstract

This invention relates to a photopolymerizable resin composition which exhibits appropriate optical density and adequate hydrophobicity upon formation of a film and is thus useful in preventing color mixing or position deviation of color ink upon injection of color ink through a jetting method using an ink-jet print into regions defined by barrier ribs (a light shielding film) formed using the photopolymerizable resin composition.

Description

technical field [0001] The present invention relates to a photopolymerizable resin composition suitable for forming a light-shielding film of an image display device such as a liquid crystal display (LCD). Background technique [0002] LCDs display images using optical anisotropy and birefringence of liquid crystal molecules. In this regard, when an electric field is applied, the orientation of the liquid crystal changes, and the light transmittance changes according to the change in the orientation of the liquid crystal. [0003] In general, an LCD is a device that displays images by arranging two substrates on which electric field generating electrodes are respectively formed so that the two electrodes face each other, injecting a liquid crystal material between the two substrates, and then A voltage is applied between the two electrodes to generate an electric field, which moves liquid crystal molecules and changes light transmittance, thereby displaying images.
