Description

TECHNICAL FIELD [0001] The present invention relates to a coloring material composition, a coloring material composition containing the same, and a resin composition containing the same. BACKGROUND ART [0002]

The present invention relates to a novel compound, a colorant composition containing the same, and a resin composition containing the same.

BACKGROUND ART [0002] In recent years, LEDs or OLED devices which do not drive liquid crystal but perform self-luminescence instead of conventional CCFL have been widely used as a light source of a liquid crystal display (LCD). When an LED or an OLED is used as a light source, red, green, and blue light is emitted by itself, so that a separate color filter is not required.

However, it is generally not easy to adjust or adjust the required color coordinates using light emitted from an LED or OLED light source. In addition, the method of improving the color purity, luminance and contrast ratio in the production of a color filter using a pigment dispersion method using already developed color materials, in particular, a pigment has reached a limit. In addition, in order to make the color filter thinner, the use amount of the color material should be reduced.

Development of a new color material is required to overcome such a problem and satisfy the requirement.
