Problems solved by technology
[0005] However, dyes (especially dyes having a monomolecular structure) are poor in persistence, thus pointing out that the dyes are not suitable for the manufacturing process of color filters
For example, photosensitive resin compositions containing monomolecular dyes may cause problems of coalescence and elution between dyes due to high-temperature thermal history during the manufacturing process of color filters, and when processed together with other materials , poor persistence of the dye
That is, a color filter comprising a dye-type photosensitive resin composition may cause problems in color characteristics and reliability

[0173] According to the composition shown in Table 1, the following photopolymerization initiators were dissolved in the following solvents and then stirred at room temperature for 2 hours. A binder resin and a photopolymerizable monomer were added thereto and stirred at room temperature for 2 hours. A colorant was added thereto and stirred at room temperature for 1 hour, and an antioxidant and a surfactant were added and stirred at room temperature for 1 hour. The obtained solution was filtered 3 times to remove impurities, thereby obtaining photosensitive resin compositions according to Examples 1 to 5 and Comparative Example 1. Each component that is used to prepare photosensitive resin composition is as follows:
[0174] binder resin
[0175] (A) Epoxy-based adhesive resin (epoxy equivalent: 177g / eq) (EHPE-3150, DIC Co., Ltd.)
[0176] (B) Acrylic adhesive resin (SKY-095 or SKY-141, Samsung SDI (Samsung SDI))
[0177] photopolymerizable monomer
[0178] Photopolym...

Abstract
The present invention relates to a photosensitive resin composition comprising a compound represented by Chemical Formula 1 and a compound represented by Chemical Formula 2 as a colorant, a photosensitive organic layer, and a color filter comprising the photosensitive organic layer. The photosensitive resin composition of the present invention can obtain color coordinates having high color reproducibility even without using an excessive amount of colorant, and can provide a color filter having improved brightness, heat resistance and chemical resistance.
Description
[0001] Cross References to Related Applications [0002] This application claims priority and benefits from Korean Patent Application No. 10-2016-0003222 filed with the Korean Intellectual Property Office on January 11, 2016, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a photosensitive resin composition, a photosensitive resin layer and a color filter comprising the photosensitive resin layer. Background technique [0004] A color filter manufactured by using a pigment-type photosensitive resin composition has limitations in brightness and contrast ratio due to the particle size of the pigment. Furthermore, in the case of a color imaging device which is an image sensor, it is required to have a small dispersed particle diameter to provide a fine pattern. In response to the above-mentioned demands, there have been continuous attempts to provide color filters with improved color characteristics s...
