BACKGROUND ART [0002] Color filters are widely used in imaging devices, liquid crystal display devices, and the like, and their application range is rapidly expanding. A color filter used for a color liquid crystal display device, an image pickup device, or the like is generally formed by uniformly applying a colored photosensitive resin composition containing a colorant corresponding to red, green and blue colors on a substrate on which a black matrix is patterned by spin coating (Hereinafter also referred to as "post-baking") is repeated for each color so as to obtain a pixel of each color As shown in FIG.

As the coloring agent in the colored photosensitive resin composition, a pigment dispersion system is generally used. For this purpose, a pigment dispersion method is used. As the pigment dispersion method, there is a method of producing a color filter by photolithography using a coloring and radiation-sensitive composition in which pigments are dispersed in various photosensitive compositions. This method has been widely used as a preferable method for producing a color filter for a large-screen and high-resolution color display because sufficient reliability can be secured against light or heat since a pigment is used.

Accordingly, Korean Patent Laid-Open No. 10-2006-0020668 (published on Mar. 03, 2006) discloses a photosensitive resin composition adhesion improving agent composed of a sulfonyl group-substituted nitrogen compound or a thiadiazole compound and an alkali-soluble resin containing the adhesion- To a photosensitive resin composition containing the photosensitive resin composition. [0003] The above-mentioned prior art has been widely applied to a silicon substrate, a glass substrate, and a metal film such as molybdenum (Mo), a metal oxide film, a non-metal oxide film, or the like on such a substrate in the production of flat panel displays (FPD) such as semiconductor integrated circuit devices and liquid crystal display devices There is a feature for improving the adhesion of the photosensitive resin composition to the substrate.

 However, the conventional photosensitive resin composition contains an additional adhesiveness improver, which causes problems such as impaired storage stability of the photosensitive resin composition and insufficient adhesion under severe conditions.

These dyes may be used alone or in combination of two or more.

The content of the dye in the colorant is preferably 0.5 to 80% by weight, more preferably 0.5 to 60% by weight, and particularly preferably 1 to 50% by weight based on the solid content in the colorant.

When the content of the dye in the colorant is within the above range, it is possible to prevent the problem of lowering the reliability of dye elution by organic solvent after pattern formation, and it is preferable because of excellent sensitivity.

The content of the colorant is preferably 5 to 60% by weight, more preferably 10 to 45% by weight based on the solid content in the colored photosensitive resin composition. When the colorant is contained in an amount of 5 to 60% by weight based on the standard, the color density of the pixel is sufficient even when a thin film is formed, and the residue of the non-cured portion is not lowered during development.

In the present invention, the total solid content in the colored photosensitive resin composition means the total content of the remaining components excluding the solvent from the colored photosensitive resin composition.

The alkali-soluble resin of the present invention is prepared by copolymerizing an ethylenically unsaturated monomer having a carboxyl group as an essential component in order to have solubility in an alkali developing solution used in a developing process for forming a pattern. In order to ensure compatibility with the dye and storage stability of the colored photosensitive resin composition, the acid value of the alkali-soluble resin is preferably 30 to 150 mgKOH / g. When the acid value of the alkali-soluble resin is less than 30 mgKOH / g, it is difficult to secure a sufficient developing rate of the colored photosensitive resin composition. When the acid value exceeds 150 mgKOH / g, the adhesion with the substrate is decreased, This problem causes the dye in the colored photosensitive resin composition to precipitate or the storage stability of the colored photosensitive resin composition to deteriorate, and the viscosity tends to rise.

A hydroxyl group may be added to secure the further developability of the alkali-soluble resin. The developing rate for imparting hydroxyl groups is improved, but the sum of the hydroxyl value of the alkali-soluble resin and the photopolymerizable compound is limited to 50 mgKOH / g or more and 250 mgKOH / g or less. When the sum of the hydroxyl groups is less than 50 mgKOH / g, a sufficient developing rate can not be secured. When it exceeds 250 mgKOH / g, the dimensional stability of the formed pattern is lowered and the linearity of the pattern becomes poor and the compatibility with the dye is deteriorated A problem of storage stability tends to occur.

Specific examples of the ethylenically unsaturated monomer having a carboxyl group include monocarboxylic acids such as acrylic acid, methacrylic acid and crotonic acid; Dicarboxylic acids such as fumaric acid, mesaconic acid and itaconic acid; And anhydrides of these dicarboxylic acids; (meth) acrylates of a polymer having a carboxyl group and a hydroxyl group at both terminals such as? -carboxypolycaprolactone mono (meth) acrylate, and acrylic acid and methacrylic acid are preferable.

In order to impart a hydroxyl group to the alkali-soluble resin, an ethylenically unsaturated monomer having a carboxyl group and an ethylenically unsaturated monomer having a hydroxyl group can be copolymerized, and a compound having a glycidyl group in a copolymer of an ethylenically unsaturated monomer having a carboxyl group Followed by further reaction. And further by reacting a copolymer of an ethylenically unsaturated monomer having a carboxyl group and an ethylenically unsaturated monomer having a hydroxyl group with a compound having a glycidyl group.

Specific examples of the butylenes unsaturated monomer having a hydroxyl group include 2-hydroxyethyl (meth) acrylate, 2-hydroxypropyl (meth) acrylate, 4-hydroxybutyl (meth) acrylate, 3-phenoxypropyl (meth) acrylate, N-hydroxyethyl acrylamide and the like, and 2-hydroxyethyl (meth) acrylate is preferable, and two or more kinds thereof can be used in combination.

The thin film irradiated with ultraviolet rays was developed with a KOH aqueous solution of pH 10.5 using a spraying method at a pressure of 0.1 MPa for 2 minutes. The glass plate coated with the thin film was washed with distilled water, and then blown with nitrogen gas, dried, and heated in a heating oven at 200 ° C for 25 minutes to prepare a color filter. The film thickness of the color filter prepared above was 2.3 탆.

(2) Evaluation analysis

In addition, the development residue was indicated as O = no development residue on the substrate, and X = development residue on the substrate.

In addition, when the generated pattern was evaluated by an optical microscope, the degree of the peeling phenomenon was indicated on the pattern. O = no peeling off of the pattern, 1 = 3 on the pattern peeling, 4 = 4 on the pattern peeling And XX = torn bundle.

The pattern straightness evaluation showed the degree of unevenness and bending occurring on the pattern when the generated pattern was evaluated through an optical microscope. O = no error in pattern, 1 = 3 pattern errors, X = pattern 4 errors or more, XX = unexplained, or impossible to measure.

The development speed, sensitivity, development residue, and pattern straightness of the color filter made of the colored photosensitive resin compositions of Examples 1 to 4 and Comparative Examples 1 to 3 were evaluated. The results are shown in Table 3 below.

Example Comparative Example One 2 3 4 One 2 3 Development speed (sec) ^a 18 19 22 22 15 16 28 Sensitivity (mJ / cm ² ) ^b 18 17 14 14 55 43 13 Developed residue ^c O O O O O O XX Pattern subtraction ^d O O O O XX △ O Pattern straightness ^e O O O O XX X △
