Description

Dye, a coloring composition comprising the same, a photosensitive resin composition for a color filter comprising the same and a color filter manufactured using the same {DYE, COLORING COMPOSITION, PHOTO-SENSITIVE RESIN COMPOSITION FOR COLOR FILTER, AND COLOR FILTER PREPARED BY USING SAME}

The present invention relates to a dye, a coloring composition comprising the same, a photosensitive resin composition for a color filter comprising the same, and a color filter manufactured using the same, and more particularly, a color filter having excellent dispersion stability and having high brightness and high contrast ratio. It relates to a dye which can be prepared, a coloring composition for a color filter comprising the same, a photosensitive resin composition for a color filter comprising the same, and a color filter prepared using the same.

The color filter is a thin film type optical component that extracts three colors of red, green, blue, and white color from white light, and enables the pixel unit to have a pixel size of about tens to hundreds of micrometers. Such a color filter includes a black matrix layer formed in a predetermined pattern on a transparent substrate for shielding the boundary between each pixel, and a plurality of colors (typically, red (R) and green (G) to form each pixel. And a pixel portion in which three primary colors of blue (B) are arranged in a predetermined order. In general, color filters can be manufactured by coating three or more colors on a transparent substrate by dyeing, electrodeposition, printing, pigment dispersion, etc. Recently, pigment dispersion using pigment-dispersible photosensitive resins has become mainstream. To achieve.

The dyeing method has a problem in that it is excellent in color characteristics using a dye, but weak in light resistance and heat resistance.

Electrodeposition method is excellent in heat resistance and light resistance by using a pigment, but when the electrode pattern is miniaturized as the pixel size is reduced, problems such as increased color unevenness and the thickness of the colored thin film at the edge may occur.

The printing method uses an ink in which pigments are dispersed, and can reduce material costs compared to other methods, but it is difficult to form highly precise and detailed images, and the thin film layer to be formed is not uniform. The color filter has an application limit.

On the other hand, the pigment dispersion method is a method of forming a colored thin film by repeating a series of processes of coating, exposing, developing and thermosetting a photosensitive resin composition containing a colorant on a transparent substrate provided with a black matrix. This pigment dispersion method has the advantage of being able to improve heat resistance and durability, which are the most important properties of the color filter, and to keep the thickness of the film uniform. The photosensitive resin composition used for manufacturing the color filter according to the pigment dispersion method generally contains a binder resin, a photopolymerizable monomer, a photopolymerization initiator, an epoxy resin, a solvent and other additives.

However, despite the advantages of the pigment dispersion method, there is a need for a method that can prevent the decrease in contrast ratio and brightness resulting from the size of the pigment particles, it is necessary to use a dye that does not form a particle of each molecule.

Pigments for forming a red color filter in the pigment dispersion method are C.I. (COLOR INDEX) red pigment 177 (hereinafter referred to as "Red177") consisting mainly of anthraquinone structure, C.I. consisting of perylene, diketopyrrolopyrrole pigment. Red pigments 224, 254 (hereinafter referred to as "Red224, Red254") are used. Currently used G7 (phthalocyanine green G (7)) has high colorability as green, but is used as a pigment for red pixels according to sRGB (standard Red Green Blue), NTSC (National Television System Committee), and EBU (Europien Broadcasting Union) standards. In order to do this, a large amount of red pigment and a large amount of yellow must be mixed, and the transmittance is lowered due to the size and amount of the pigment particles.

Therefore, in order to form a red pixel displaying a region of high coloring power (high concentration region) on a color coordinate, the content of the red pigment must be increased. There is a problem that the transmittance of the pixel is lowered.

 As a method for securing a high transmittance, there is also a method of shifting the color coordinates to the yellow direction using a high concentration of yellow pigment, but there is a problem that the total content of the pigment increases because the content of the yellow pigment increases.

Therefore, instead of increasing the pigment content, by replacing the pigment with a dye or adding a dye to the pigment dispersion, the thickness of the pixel is made thin so as not to increase the content of the pigment, and a pigment derivative is synthesized to achieve dispersion with the pigment. By increasing the dispersibility, not only high brightness but also high contrast ratio can be exhibited and dispersion stability is secured.

The dye of the present invention has a functional group substituted in the benzene ring as shown in the general formula (1), and has improved solubility than conventional pigments. The red dye of the present invention represented by Chemical Formula 1 has a structure similar to that of C.I.Red 224, which is a conventionally used red pigment, and may allow pi-orbital interaction and hydrogen bonding with the pigment.

The dye according to the present invention emits red color, and may be used alone or in combination with a red pigment such as C.I.Red224.

The dye is preferably included in 3 to 15% by weight of the total amount of the coloring composition of the present invention, more preferably contained in 5 to 10% by weight. When the dye is included in 3 to 15% by weight, it is possible to maintain the appropriate viscosity while the color expression effectively occurs, there is an advantage in the excellent optical, physical and chemical quality when applied to the product.

(A2) binder resin

In the coloring composition of this invention, the polymer which has one or more acidic groups can be used preferably as binder resin, Although these can be used individually or in mixture of 2 or more types, It is not specifically limited to this. A carboxyl group, a sulfonic acid group, or a phosphoric acid group is mentioned as said acidic group.

Examples of the binder resin include polyalkyl methacrylates such as polyethyl methacrylate and polyethylhexyl methacrylate; Polyaryl methacrylates such as polybenzyl methacrylate and the like; Polyglycerol methacrylate; Polycarboxylic acrylate; Polystyrene; Copolymers thereof; And it is preferable to use the polyacrylate resin selected from the group consisting of these.

In addition, polyaminopropyl acrylate, polycyclohexyl acrylate, polyphenoxy acrylate, polymethoxy ethyl acrylate, poly methoxy diethylene glycol acrylate, poly methoxy propylene acrylate, poly acrylonitrile, polyhydroxy Methyl methacrylate, polyethyl methacrylate, polybenzyl methacrylate, polyethylhexyl methacrylate, polymethyl methacrylic acid, polymethacrylic acid and the like can also be preferably used.

The binder resin used in the present invention preferably has an acid value of 70 to 150mKOH / g. The acid value of the binder resin is determined by the amine value of the dispersant used in the composition, but the dispersant used in the present invention has an amine value of 10 to 200 mgKOH / g. The acid value of the binder resin offsets the amine value of the dispersant used to increase the stability of the coloring composition for color filters, and when the photosensitive resin composition for color filters is manufactured using the color filter coloring composition, the development of the non-exposed portion is easy. To make it work. Of course, in order to improve the developability of the non-exposed part, the acid value of the binder resin is most important among the photosensitive resin compositions for color filters, but the acid value of the binder resin used in the production of the color composition for color filters is also important. In particular, since the amine value of the dispersant used in the present invention is considerably high, the higher the acid value of the binder resin in order to offset it, the more preferable, especially when the acid value of the binder resin is 80 to 130mKOH / g.

The binder resin preferably has a weight average molecular weight of 3,000 to 30,000, more preferably 15,000 to 30,000. If the weight average molecular weight of the binder resin is too low, less than 3,000, there is a fear of viscosity increase, if it exceeds 30,000, since the viscosity at the time of initial dispersion is high and dispersion is not easy, the binder resin used in the present invention is dispersible And a weight average molecular weight within the above range in terms of balance of viscosity.

In addition, the binder resin is preferably used in an amount of 1 to 50 parts by weight, more preferably 5 to 30 parts by weight, based on 100 parts by weight of the dye of the present invention. If the content of the binder resin of the present invention is too low, less than 1 part by weight, effective dispersion is not achieved to ensure the dispersion stability, if the content is too high exceeding 50 parts by weight, the viscosity of the composition rises sharply Since the optical, physical and chemical qualities of the product may be degraded, the binder resin of the present invention is preferably used in the above content range in terms of balance of dispersion stability and viscosity.

(A3) solvent

There is no restriction | limiting in particular as a solvent used in the coloring composition of this invention, It can use 1 type or in mixture of 2 or more types from a well-known thing.

The solvent used in the color filter coloring composition of the present invention is used in an amount of 10 to 1,000 parts by weight, preferably 20 to 500 parts by weight based on 100 parts by weight of the total amount of the dye and the pigment. If the amount of the solvent used is too low, less than 10 parts by weight, the viscosity of the color composition for color filters is too large, which is undesirable. If the amount of the solvent is too high, the viscosity of the composition is lowered, which may affect the physical and optical properties of the product. It can be undesirable.

(A4) pigment

Pigments of the present invention include a yellow pigment selected from the group consisting of C.I.Yellow138, C.I.Yellow139, C.I.Yellow150 and C.I.Yellow183; Red pigment selected from the group consisting of C.I.Red177, C.I.Red224, C.I.Red242 and C.I.Red254; And combinations thereof may be suitably used.

In particular, it is preferable that the yellow pigment represented by following formula (2) is used for the coloring composition for color filters of this invention.

[Formula 2]

CIYellow183, a sulfonate yellow pigment of Formula 2, exhibits a solubility of 8% by weight or more in N-methylpyrrolidone (NMP), and is in solution with the dye represented by Formula 1 of the present invention. Composition is possible. Therefore, the C.I.Yellow183 can be added together with the dye to the color composition for color filters of the present invention, it is possible to improve the transmittance.

The yellow pigment of the present invention has an average particle diameter of 40 to 100 nm, more preferably has an average particle diameter of 40 to 50 nm. The yellow pigment may be refined to a size in the range of 10 to 50 nm through the pretreatment such as oval or kneading in the shape of the cross section, and may also be changed to a spherical pigment having a circular cross section. The yellow pigment can be made into a pigment having a spherical particle of 40 to 50nm through the need for a needle-like pigment of 80nm or more, in the case of such a pigment is excellent in dispersibility and advantageous in terms of coloring power. In addition, the smaller the particles of the pigment, the more the shape of the particles from the rough needle shape to the round ellipse shape can reduce the scattering of light can have the effect of improving the contrast ratio.

The yellow pigment is preferably used in an amount of 10 to 40 parts by weight, more preferably 20 to 30 parts by weight, based on 100 parts by weight of the red dye of the present invention represented by the formula (1). When the content of the yellow pigment is less than 10 parts by weight, a relatively high content of the dye may cause a problem that the heat resistance and light resistance is reduced, when exceeding 40 parts by weight is excellent in durability but relatively high proportion of the yellow pigment There is a problem that it is difficult to achieve the desired color.

(A5) dispersant

The coloring composition of this invention can use a dispersing agent further in order to disperse | distribute a pigment uniformly in a solvent.

In the present invention, as a dispersant, a polyester compound, a polycarboxylic acid ester compound, an unsaturated polyamide compound, a polycarboxylic acid compound, a polycarboxylic acid alkylamine salt compound, a polyacrylic compound, a polyethyleneimine compound, a polyurethane compound Etc. can be used, and these can be used individually or in mixture of 2 or more types.

The dispersant preferably has an amine number of 10 to 200 mgKOH / g, more preferably 40 to 200 mgKOH / g, even more preferably 50 to 150 mgKOH / g. If the amine value of the dispersant is 10 mgKOH / g, the amine value is too low, the dispersibility improvement effect is insignificant, and if the amine value exceeds 200 mgKOH / g, the amine value is too high, there is a possibility that the developability is lowered, which is not preferable.

The dispersant is preferably used in 10 to 80 parts by weight, more preferably 20 to 60 parts by weight based on 100 parts by weight of the pigment contained in the coloring composition of the present invention. If the content of the dispersant is too low, less than 10 parts by weight, effective dispersion does not occur, there is a fear that the dispersion stability is lowered. If the content of the dispersant exceeds 80 parts by weight, excessively high, the viscosity of the composition rises rapidly, the optical and physical when applying the product Since the chemical quality may be lowered, it is preferably included in the content range in consideration of the balance of dispersion stability and viscosity.
