Colored photosensistive resin composition, coating film of colored photosensitive resin composition, photosensitive resin transfer material

Abstract

A colored photosensitive resin composition comprising at least (1) an alkali-soluble binder, (2) a monomer or an oligomer, (3) a photopolymerization initiator or a photopolymerization initiator system, and (4) a colorant The colored photosensitive resin composition of R, G or B, and contains a specific amount of a specific pigment as the above-mentioned colorant. This invention also relates to the color filter etc. which use this colored photosensitive resin composition for formation of each R, G, or B photosensitive resin layer. According to the present invention, it is possible to provide a color filter that has good chromaticity and can realize high color purity especially when used in a large-screen liquid crystal display device such as a notebook computer monitor or a TV monitor, and is suitable for use in such a filter. A colored photosensitive resin composition for a color filter.

[0131] Wash the alkali-free glass substrate with a UV washing device, then use a detergent to scrub, and then use ultrapure water to perform ultrasonic cleaning. This substrate was heat-treated at 120° C. for 3 minutes to stabilize the surface state.

[0132] The substrate was cooled and the temperature was adjusted to 23° C., and then the components described in the following Table 2 were coated with a glass substrate coater (manufactured by FAS Japan Co., Ltd., trade name: MH-1600) with a slit nozzle. Composition of the following colored photosensitive resin composition K1. Then use VCD (vacuum drying device; Tokyo Ohka Co., Ltd.) to dry for 30 seconds to volatilize part of the solvent and make the coating layer have no fluidity. The required coating solution was prebaked at 120° C. for 3 minutes to obtain a photosensitive resin layer K1 with a ...

[0204] —Measurement of Chromaticity—

[0205] The chromaticity of the color filter obtained above was measured with a pinhole diameter of 5 μm using a microspectrophotometer (manufactured by Olympus Optical Co., Ltd.; OSP100), and calculated as a result of a field of view of F10 light source of 2 degrees. The results (xyY values, and the difference (ΔE) from the target chromaticity) are shown in Tables 6-8.
