Description

Technical Field [0001] The present invention relates to a curable resin composition for ink-jet, a color filter, and an image display device having the same.

The present invention relates to a curable resin composition for an ink jet, a color filter and an image display apparatus having the same, and more particularly, to a curable resin composition for inkjet, which has excellent flatness of an ejected ink, a color filter, will be.

Most of the color filters used in the image display apparatus are manufactured by the pigment dispersion method. The pigment dispersion method is a method in which a thin film of chromium or the like is used as a raw material to form a pattern by photolithography and development and a blue, green and red photosensitive resin is coated on the thus formed barrier rib by spin coating, slit coating or the like Followed by patterning by photolithography and development, respectively, followed by curing.

This method has an advantage that the applied film thickness is uniform, but when patterning of each color is formed, about 70% of the material to be coated is lost, and the cost of the exposure apparatus, Installation cost is required, and there is a difficulty in yield control because the process line is long. In recent years, as the display material substrate has become larger, the costs of the above process and installation equipment are expected to increase further.

An ink jet method has been proposed as an alternative to this. The inkjet method can color a plurality of colors including red, green and blue at one time by a technique in which each ink is colored by spraying a curable resin composition only on an opening of a partition wall formed by using an inkjet head, , Time and cost can be greatly reduced. The inkjet method using the curable resin composition satisfies desired color coordinates or film thickness by injecting a specific amount of ink to the pixel opening of the barrier rib.

Therefore, it is essential that the resin composition for inkjet for forming a color filter basically has a pattern forming ability and adhesion with a substrate, as well as securing the flatness of the applied film. Furthermore, when a yellowing phenomenon occurs after curing, the resin composition for forming a color filter may affect the color of a colorant originally intended.

Conventionally, a thermal polymerization initiator has been used in the inkjet curable resin composition, but the thermal polymerization initiator has a problem in that the brightness after curing is lowered.

In order to solve these problems, various studies on various photoinitiators have been carried out. Among them, oxime compounds absorb ultraviolet rays and have almost no color, have high radical generation efficiency, and have good stability in the composition.

As the oxime compounds, α-oxooxime derivatives have been disclosed in JP-A-61-118423, JP-A-1-068750 and JP-A-3-004226, and US Pat. No. 4,255,513 Discloses an oxime ester compound using p-dialkylaminobenzene. U.S. Patent No. 4,202,697 discloses an acrylamino-substituted oxime ester compound, and U.S. Patent No. 4,590,145 discloses a benzophenone oxime ester compound. U.S. Patent No. 5,776,996 discloses a β-aminooxime compound, and U.S. Patent No. 6,051,367 discloses an oxime ester compound in which an ethylenically unsaturated group is contained in a molecular structure. In addition, International Patent Publication No. 00/052530 discloses oxime ether, oxime ester, oxime sulfonate compounds, and International Patent Publication No. 02/100903 discloses a process for the production of oxycarboxylic acids by coupling with alkyl acyl ketones, diarylketones or ketocoumarines &Lt; / RTI > is disclosed.

Among these oxime compounds, compounds having a long conjugation length and absorbing long wavelength light have a slight color and may affect the color when applied to optical applications. On the other hand, a compound absorbing light having a short wavelength has a low photoreactivity and low efficiency as a photoinitiator.

On the other hand, in general, in the case of a barrier rib used for a color filter, since the property of repelling the dropped ink is weak, the ink amount is not filled in the barrier rib or ink is overflowed to adjacent pixels, A method of adding a material or a process of increasing the repulsive force by fluorine plasma treatment after the production of the barrier is added.

However, in such a method, the dropping ink does not spread properly in the glass in the pixel due to the repulsive force of the barrier rib, or the color separation occurs due to the separation from the barrier rib after the baking process. Such an additional process is a manufacturing process, Resulting in lower efficiency of time and cost savings. Further, in the conventional curable resin composition, a leveling agent is used as one of methods for improving the composition so as to control the shape of ink in pixels such as color dropout and spacing in a flat manner. However, And problems such as overflowing of the barrier ribs, surface abnormality, and deterioration of intrinsic properties of the curable resin composition occur due to excessive introduction.

In particular, when the curable resin composition for an ink jet according to the present invention further comprises a colorant, it can be used for forming a color layer of a color filter.

Hereinafter, a method of forming a pattern using the coloring agent for ink-jet curable resin composition according to the present invention, and a color filter including the pattern will be described in more detail.

The method for forming a pattern of a curable resin composition for an inkjet according to the present invention comprises the steps of applying the inkjet curable resin composition described above to a predetermined area by an inkjet method and curing the applied curable resin composition for an inkjet .

First, a curable resin composition for an ink jet is injected into an ink jet injector to print on a predetermined area of a substrate.

The substrate is not limited. For example, a substrate having a flat surface such as a glass substrate, a silicon substrate, a polycarbonate substrate, a polyester substrate, an aromatic polyamide substrate, a polyamideimide substrate, a polyimide substrate, an Al substrate, . These substrates can be subjected to pretreatment such as chemical treatment with a chemical such as a silane coupling agent, plasma treatment, ion plating treatment, sputtering treatment, vapor phase reaction treatment, vacuum deposition treatment and the like. When a silicon substrate or the like is used as a substrate, a charge coupled device (CCD), a thin film transistor (TFT), or the like may be formed on a surface of a silicon substrate or the like. Also, a barrier matrix may be formed.

In order to form an appropriate phase on the substrate by jetting in the piezo ink jet head, which is an example of an ink jet injector, characteristics such as viscosity, fluidity, pigment particle, etc. must be balanced with the ink jet head. The piezo inkjet head used in the present invention ejects ink having a droplet size of about 10 pL to 100 pL, preferably about 20 pL to 40 pL, though not limited thereto.

The viscosity of the curable resin composition for inkjet is suitably in the range of about 3 to 30 cP, more preferably in the range of 7 to 20 cP.

The pigment particles used as a coloring agent in the curable resin composition for inkjet preferably have a size of about 50 to 500 nm, more preferably 100 nm or less. When the pigment particle size is 500 nm or more, the flowability of the pigment particles is reduced and the injection becomes uneven. When the particle size is 50 nm or less, it is difficult to secure the dispersion stability of the pigment.

Next, a color filter according to the present invention includes a color layer formed by the pattern formation method. That is, the color filter includes a color layer formed by applying the curable resin composition for inkjet according to the present invention in a predetermined pattern and curing it.

The configuration of the color filter is well known in the art, and a detailed description thereof will be omitted.

That is, all the image display apparatuses to which the color filter of the present invention can be applied are included in the present invention. Examples of the image display device include a liquid crystal display device, an OLED, and the like. As a more specific example, a counter electrode substrate having a thin film transistor (TFT element), a pixel electrode and an alignment layer is faced at a predetermined interval, and a liquid crystal material is injected into the gap portion to form a liquid crystal layer, . There is also a reflective liquid crystal display device in which a reflective layer is provided between the substrate of the color filter and the colored layer.
