Abstract

In the present specification, a polymer containing a coloring material and a dye containing the same are described.

Description

POLYMER INCLUDING COLORANT, AND DYE COMPRISING THE SAME [0002]

The present invention relates to novel polymers and dyes containing them.

In recent years, LEDs, OLEDs, and QDs have been widely used as light sources for liquid crystal displays (LCDs) instead of conventional CCFLs. However, in order to manufacture thin-film displays and flexible displays, display products using a self-emission such as an LED, OLED or QD as a unit pixel have been developed and produced.

However, display using LEDs, OLEDs, and QDs as unit pixels is difficult to maximize, so even when using LEDs, OLEDs, QDs, etc., .

In order to realize a desired color, a light source and an appropriate color filter are required, and it is difficult to realize a desired color coordinate by using a currently used color material, and development of a new color material is required.

In addition, the pigment dispersion method applied to the production of color filter resists has been striving to realize high brightness and high contrast through atomization of pigments. However, in order to realize a higher level of high brightness, high contrast and new color coordinates, In addition to pigments, new pigments and dyes must be excavated.

In the case of a color filter using an existing pigment type color resist, the number of pigments having absorption and transmission spectra suitable for the light source to be used is limited, and it is difficult to finely control absorption and transmission spectra. In the case of a color filter using a dye type color resist or a dye pigment hybrid color resist, absorption and transmission spectra suitable for a light source to be applied can be obtained by using various dyes. In this case, a higher color reproduction rate, can do.

Heat resistance evaluation

The photosensitive resin composition is spin-coated on a glass (Corning) of 5 cm x 5 cm and pre-baked at 100 ° C for about 100 seconds to form a film. The substrate and the photomask were formed in the film (photo mask) and the 40mJ / cm ² exposure amount was examined and the distance between a 300㎛, using an exposure device (Hoya-shott社). The exposed substrate was developed in a developing solution (KOH, 0.05%) for 60 seconds and post baked (PB) at 200 캜 for 20 minutes to obtain a color pattern.

A color pattern was obtained through a spectroscope (MCPD-Otsuka) to obtain a transmittance spectrum in a visible light range of 380 nm to 780 nm. The obtained transmittance spectrum and the C light source backlight are used and ΔEab is calculated using the obtained value E (L ^* , a ^* , b ^* ), and it is shown in Table 11 below.

^{ΔE (L *, a *,} b *) = {(ΔL *) 2 + (Δa *) 2 + (Δb *) 2} 1/2

The smaller value of? E means that the color change is small and the heat resistance is excellent.

Chemical resistance evaluation

The photosensitive resin composition is spin-coated on a glass (Corning) of 5 cm x 5 cm and pre-baked at 100 ° C for about 100 seconds to form a film. The substrate on which the film was formed was irradiated on the entire surface at an exposure dose of 40 mJ / cm ² using an exposure machine (Hoya-shott). The exposed substrate was developed in a developing solution (KOH, 0.05%) for 60 seconds, post baked at 200 ° C for 20 minutes, cut into 1 cm x 5 cm and transferred to 20 g of NMP solution Minute).

NMP solution was measured by UV spectrum and Abs. The results are shown in Table 12 and Fig.

Abs Example 1 0.045 Example 2 0.044 Example 10 0.035 Example 11 0.032 Comparative Example 1 0.23 Comparative Example 2 0.233

As shown in the above table, the polymer type color material according to the present invention is superior to the monomolecular type color material used in the comparative example in terms of heat resistance and chemical resistance.

The chemical resistance Test Abs value in FIG. 1 indicates chemical resistance. When the Abs value is small, the chemical resistance is excellent, and when it is large, the chemical resistance is weak. In other words, if the chemical resistance is excellent, the absent amount of the coloring material in the NMP solution is small and the Abs value is small. If the chemical resistance is poor, the absorption amount of the coloring material in the NMP solution is large.
