Description

[Technical Field] The present invention relates to a colored photosensitive resin composition, and a color filter and a liquid crystal display device using the colored photosensitive resin composition. [Prior Art] A display body such as a liquid crystal display device has a structure in which a liquid crystal layer is cooled between two substrates which are opposed to each other and formed with a pair of electrodes. Further, a color filter including pixel regions of respective colors of red (R), green (G), and blue (B) is formed on the inner side of one of the substrates. A black matrix is usually formed in the color filter to divide each of the pixel regions of red, green, and blue. Generally, color filters are manufactured by lithography. Namely, first, a black colored photosensitive resin composition is applied onto a substrate and dried, and then exposed and developed to form a black matrix. Then, the colored photosensitive resin compositions of the respective colors of red, green and blue are repeatedly coated, dried, exposed and developed, and pixel regions of respective colors are formed at specific positions to produce a color filter. As a material of the color filter, for example, Patent Document 1 to Patent Document 3 disclose a coloring photosensitive resin composition containing a photopolymerizable compound, a photopolymerization initiator, and a colorant. Moreover, in recent years, the industry has hoped to increase the contrast of liquid crystal display devices and to improve the necessity of improving the optical density (ODD) value of the black matrix.

Further, it is also desired to increase the color density in the pixel regions of the respective colors. Therefore, it is preferable that the color photosensitive resin composition for forming the pixel regions of the respective colors has a high flow characteristic and a high color density. The present invention has been made in view of the above problems, and an object thereof is to provide a photosensitive resin composition which can realize high flow characteristics and a high OD value or color density.

Phenolphthalein type epoxy resin 2 3 5 g (epoxy equivalent 2 3 5 ), tetramethylammonium chloride 1 10 0 mg, 2,6-di-t-butyl-4-methylphenol 100 mg and acrylic acid 72.0 g, while blowing air at a rate of 25 ml/min, was heated and dissolved at 90 ° C to 100 ° C. Then, the solution was gradually warmed up while the solution was cloudy, and heated to 120 ° C. It is completely dissolved. At this time, although the solution gradually becomes transparent and viscous, stirring is continued in this state, during which the acid value is measured, and heating and stirring are continued until the acid value is less than 1.0 mg Κ Ο H / g. It takes 12 hours to reach the goal. The solution was then cooled to room temperature to obtain a bisphenol type epoxy acrylate. Next, 600 g of 3-butoxyacetate acetate was added to 307.0 g of the above bisphenol type epoxy acrylate 27 200921271 ester obtained in this manner, and then dissolved, and then diphenyl fluorenone tetradecanoic dianhydride was mixed. 8 0 · 5 g and 1 g of tetraethylammonium bromide were slowly warmed up and reacted at 110 ° C to 1 1 5 ° C for 4 hours. After confirming the disappearance of the acid anhydride, 3,8,0 g of 1,2,3,6-tetrahydrophthalic anhydride was mixed and reacted at 90 ° C for 6 hours to obtain a photopolymerizable compound 1. The disappearance of the acid anhydride was confirmed by an I R spectrum (i n f r a r e d s p e c t r u m, infrared spectrum). [Preparation of coloring photosensitive resin composition] (A) component (photopolymerizable compound): photopolymerizable compound 1 (weight average molecular weight: 3,400, solid content: 55%, solvent: acetic acid 3 - oxime) Butyl vinegar) ... 23.6 parts by weight, and dipentaerythritol hexaacrylate acid ...... 4.8 parts by weight of component (B) (photopolymerization initiator): "IRGACURE OXE 02 (trade name, manufactured by Ciba Specialty Chemicals Co., Ltd.) 1. 4 parts by weight of component (C) (phosphate compound): 2-ethylhexyldiphenyl phosphate (3) Parts by weight (D) (colorant): Carbon dispersion "CF Black EX- 1 4 5 5" (trade name, manufactured by Royal Color Co., Ltd., high-resistance carbon: 24%, dispersant: 5%, solvent: 3-Oxyloxybutyl acetate (100 parts by weight) was adjusted by using the following mixed solvent so that the solid content concentration of the above components was 18% by weight. (S) component (solvent): 3-methoxybutyl acetate/cyclohexanone/propylene glycol monoterpene ether acetate I = 55/30/15 (weight ratio)) After mixing the mixtures for 2 hours using a stirrer, The transition was carried out using a 5 // m film transition to obtain a colored photosensitive resin composition. 28 200921271 (Formation method of hardened resin pattern)

[Comparative Example 2 - 1 and Comparative Example 2 - 2] A cured resin pattern was formed in the same manner as in Example 1 except that the component (C) was replaced with the following components. Phthalate compound: diisononyl phthalate Comparative Example 2 - 15 parts by weight

Comparative Example 2 - 2 1 0 parts by weight [Comparative Example 3-1, Comparative Example 3-2] A cured resin pattern was formed in the same manner as in Example 1 except that the component (C) was replaced with the following components. Phthalate compound: bis(2-ethylhexyl) phthalate Comparative Example 3 - 15 parts by weight Comparative Example 3 - 2 1 0 parts by weight [Comparative Example 4] In addition to replacing (C) component A cured resin pattern was formed in the same manner as in Example 1 except for the following components.

O-phthalic acid ester compound: butyl benzyl phthalate (5 parts by weight) [Evaluation] The 0D value and the taper angle of the cured resin pattern formed by the above examples and comparative examples (the pattern is in contact with the substrate) The angle between the surface and the substrate surface) and the shrinkage rate were evaluated. The results are shown in Table 1. In addition, the 0D value was measured using "Gretag Machbeth D-200-2" (trade name, manufactured by Machbeth Co., Ltd.) and the film thickness of the cured resin pattern was 1 #m. The cone angle is determined using a cross-sectional photograph of the formed pattern. Further, the shrinkage ratio indicates the ratio of the film thickness of the cured resin pattern after post-baking to the film thickness of the resin composition film after exposure. [Table 1] 0D / β \ 锥 cone angle shrinkage Example 1 4. 5 74 degrees 87% Example 2 4.6 52 degrees 84% Example 3 4.7 39 degrees 80% Example 4 4.6 65 degrees 86% Comparative Example 1 4.4 84 degrees 90°/〇Comparative Example 2-1 4.4 75 degrees 88% Comparative Example 2-2 Cannot be measured without pattern Cannot be measured Comparative Example 3-1 4.4 76 degrees 88% Comparative Example 3-2 Cannot be measured No pattern cannot be measured and compared Example 4 Cannot be measured without pattern Cannot be measured Comparative Example 5 Cannot be measured without pattern Cannot be measured Comparative Example 6 No pattern can be measured No measurement is impossible. In Table 1, Comparative Example 2 - 2, Comparative Example 3 - 2 and Comparative Example 4 to Comparative Example 31 200921271 In the development step in the resin composition hardening pattern forming method, the resin composition film is peeled off from the substrate, and the pattern cannot be formed. Therefore, the values of the 0D value and the shrinkage ratio cannot be measured. Table 1 shows the system in which the components (C) were added, the system of Example 1 to Example 4, the system in which the component (C) was not added (Comparative Example 1), and the system in which phthalic acid ester was added instead of the component (C). (Comparative Example 2 - 1 and Comparative Example 3 - 1 ) The value of the shrinkage ratio was smaller (i.e., the film thickness after post-baking was significantly contracted), the 0D value was increased, and the taper angle was decreased (i.e., the flow characteristics were improved). Therefore, it is understood that by adding the component (C), the increase in the Δ value and the improvement in the flow characteristics can be simultaneously achieved. Further, in Examples 1 to 4, the substrate adhesion was also good. In contrast, in Comparative Example 2-2, Comparative Example 3-2, and Comparative Example 4 to Comparative Example 6, the pattern was peeled off from the substrate after development. It is understood that the substrate has poor adhesion and is not suitable as a colored photosensitive resin composition. Further, from the results of Examples 1 to 3, it is understood that as the amount of the component (C) is increased, the 0D value and the flow characteristics are improved. At the same time, it is understood that the substrate adhesion is good even if the amount of the component (C) is increased, and in the case other than the component (C), in particular, as in Comparative Example 2-1 to Comparative Example 3 - As a result of 2, when the amount of addition was increased, the substrate adhesion could not be achieved at the same time, and it was not related to the increase in the Δ value or the flow characteristics.
