Description

Coloring composition and coloring inhibitor composition

The present invention relates to a coloring composition and a coloring inhibitor composition containing the same.

In recent years, the use of black matrix coloring compositions involves many aspects, for example, it is used in the gaps between the coloring patterns in the display area of the screen or the edges of the display area in flat panel displays such as liquid crystal or plasma, and in liquid crystal displays using TFT, a light shielding film (black matrix) is set on the light-shielding side of the TFT. In addition, it plays the following roles: in liquid crystal displays, it mainly prevents the leakage of light from the backlight from being reflected on the screen, and in plasma displays, it mainly prevents the bleeding caused by the turbidity of each color light from being reflected on the screen, thereby improving the display characteristics (contrast and color purity).

For example, in a color filter used to convert white light of a liquid crystal display backlight into colored light, it is usually manufactured by forming pixels of different hues of red, green, and blue in a striped or mosaic pattern on the surface of a transparent substrate such as glass or plastic film formed with a black matrix.

In addition, in a touch panel formed by combining an image display device and a position input device, a filter formed with a black matrix is also used as a light shielding film. So far, it is generally formed on the side opposite to the sensor substrate through a cover glass. However, with the increasing demand for lightweight touch panels, in order to achieve even lighter weight, a technology is being developed to simultaneously form a light shielding film and a touch sensor on the same side of the cover glass.

For example, Patent Document 1 discloses a technique for imparting a shielding property, etc., by using a specific pigment and carbon black as a coloring agent in combination in a photosensitive coloring composition for forming a color spacer and setting the content ratio of the carbon black to a specific range.

For example, Patent Document 2 discloses a technology that ensures a balance between light absorption in the ultraviolet region and the visible light region by appropriately combining types of pigments with different light absorption characteristics, thereby maintaining light shielding properties and the voltage retention rate of liquid crystal.

However, when the solvent resistance of the coloring composition of the black matrix of the liquid crystal layer constituting the image display device is low, cracks or defects may occur in the pixel pattern, or the coloring components may be eluted from the pixel pattern. In the above-mentioned technology, no research has been conducted on solvent resistance, and it is hoped to develop a coloring composition for a black matrix that can obtain a black resist pattern with excellent solvent resistance.
