Description

A triazine derivative, a pigment dispersing aid containing the same and a pigment dispersion containing the same,

The present invention relates to a triazine derivative, a pigment dispersion aid containing the same, and a pigment dispersion containing the same, and more particularly, to a pigment dispersion containing a triazine derivative having excellent heat resistance, a pigment dispersion aid containing the pigment, To a colored photosensitive resin composition comprising a pigment dispersion.

A color filter used in a liquid crystal display is manufactured by forming patterns of three primary colors, that is, red, green and blue on a glass substrate.

The process of producing a color pattern includes uniformly applying a photosensitive coloring composition containing a coloring agent corresponding to each color pixel on a substrate, heating-drying the applied composition to form a film Selectively exposing and drying the dried film using a mask of a desired shape, and heating and curing the developed film.

The coloring agent of the photosensitive resin composition used in such a process generally uses a pigment.

Recently, in accordance with the trend of display technology innovation, a pigment dispersion having characteristics of high transmittance (luminance) and high contrast is required to save power of a display for a liquid crystal display device, and a color gamut is expanded The goal is to achieve a high color recall rate.

In order to achieve such a goal, the pigment concentration must be high, but a high level of pigment dispersion is required because the high concentration of the pigment degrades the storage stability of the pigment dispersion itself and the storage stability and pattern fairness even when it is made into a resist .

In addition to pigments, dispersants, and resins, a pigment dispersion aid that stabilizes the pigment surface is used as the pigment dispersion. The pigment dispersing aid can stabilize the surface of the pigment to prevent the storage stability of the pigment dispersion and the sublimation of the pigment, and further, when the pigment dispersion aid is applied to the surface treatment of the pigment, the pigment surface is more stabilized, Can be dispersed.

However, the conventional pigment dispersing aid has a structure different from that of the pigment as a whole by applying substitution groups to the same parent skeleton as the pigment, so that the color spectrum of the pigment and the conventional pigment dispersing aid is changed, . As a result, the luminance of the image displayed on the display is lowered, which does not meet the development target of the current display aiming at low power.

Conventionally, a pigment dispersant and a dispersing aid having a triazine ring as a parent skeleton are known, but the known structure is limited to a role as a pigment surface treatment agent, and a pigment dispersion auxiliary having still improved properties is required.

The pigment included in the pigment dispersion of the present invention can be obtained by reacting a compound as a raw material of an organic pigment or pigmenting a pigment preparation in the presence of a pigment surface treatment agent containing the triazine derivative of the present invention.

That is, the pigment contained in the pigment dispersion of the present invention may be a fine pigment obtained by surface-treating the prepared pigment with the triazine derivative of the present invention.

The auxiliary pigment in the present invention is a compound obtained by reacting a raw material compound as a base of a condensed polycyclic pigment and having a large particle size (for example, about 10 to several hundreds of 탆).
