Problems solved by technology

[0004] However, matching or controlling the desired color coordinates using light from an LED or OLED light source is often not straightforward
In addition, when color filters are manufactured with already developed colorants (especially pigments) using the pigment dispersion method, the method of improving color purity, brightness and contrast range reaches the highest limit

[0137]

[0138] 1) Preparation of compound A-3

[0139] Under shielding conditions, 3.000 g (7.403 mmol) of A-1 and 0.753 g (2.96 mmol) of A-2 were introduced into 30 g of N-methylpyrrolidone (NMP), and the resultant was reacted at 150° C. 4 hours. The solvent was removed under vacuum, and 1.174 g (1.184 mmol) of compound A-3 were obtained by subjecting the crude compound to column chromatography.

[0140] 2) Preparation of Compound A-5

[0141]5.000 g (5.041 mmol) of Compound A-3 and 2.443 g (20.162 mmol) of Compound A-4 were introduced into 50 g of N-methylpyrrolidone (NMP), and the resultant was reacted at 150° C. for 5 hours. The resultant was cooled to room temperature, 35% HCl was added thereto, and the resultant was stirred. The solvent was removed under vacuum, and 1.756 g (1.512 mmol) of compound A-5 was obtained by column chromatography.

[0153] Substrate preparation

[0154] The compound prepared by the above synthesis was spin-coated on glass (5×5 cm) and prebaked at 100° C. for 100 seconds to form a film. The distance between the film-formed substrate and the photomask was 250 μm, and a stepper was used at 40 mJ / cm 2 The exposure dose irradiates the entire surface of the substrate. Thereafter, the exposed substrate was developed in a developing solution (KOH, 0.05%) for 60 seconds, and post-baked at 230° C. for 20 minutes to prepare a substrate.

Abstract

The present specification relates to a novel xanthene-based compound, a colorant composition containing the same, and a resin composition containing the same.

Description

technical field [0001] This application claims Korean Patent Application No. 10-2015-0133199 filed with the Korean Intellectual Property Office on September 21, 2015 and Korean Patent Application No. 10-2016-0104939 filed with the Korean Intellectual Property Office on August 18, 2016 the priority and interest of , the entire contents of which are incorporated herein by reference. [0002] This specification relates to a novel xanthene compound, a colorant composition containing the same, and a resin composition containing the same. Background technique [0003] As a light source of a liquid crystal display (LCD), LED or OLED devices that perform self-luminescence using neither driving nor liquid crystals have been widely used instead of existing CCFLs. When LEDs or OLEDs are used as light sources, they themselves generate red, green and blue light, and thus do not require separate color filters. [0004] However, matching or controlling the desired color coordinates using...
