[0002]

2. Description of the Related Art Liquid crystal displays (hereinafter abbreviated as LCDs).
Utilizing features such as thinness, small size, and low power consumption, is currently used for display units such as watches, calculators, TVs, and personal computers. In recent years, color LCDs have been developed and OA / AV
It has begun to be used in many applications such as navigation systems and viewfinders, mainly in equipment, and the market is expected to expand rapidly in the future.

As shown in FIG. 1, a color filter for displaying a color image on an LCD is formed on a substrate 2 such as a glass plate on which a BM (black matrix) 1 having a lattice pattern is formed. 3) Color pixels 3 (about 100 × 100 × 2 μm) composed of B (blue) are sequentially formed, and a transparent overcoat layer (OC) 4 is formed thereon. 5 is a polarizing plate and 6 is an ITO electrode.

[0004] In the color LCD, the color filter 7 has an LC
D, the display screen can be colored by transmitting backlight light through a color filter. 8 is an alignment film, 9 is a liquid crystal, 10 is a seal material, 11 is a top coat layer, 12 is an ITO electrode, 13 is a substrate such as a glass plate, 14
Is a polarizing plate.

At present, color filters are mainly manufactured using a dyeing method. However, in this method, a step of forming a pixel by applying a transparent photosensitive resin on a glass substrate, drying, exposing, and developing, dyeing with a dye, and then forming a color mixing prevention layer is required to be repeated three times. Therefore, the number of steps is large and the cost is high. Further, since a dye is used as a coloring agent, there is a disadvantage that reliability (weather resistance and heat resistance), which is an important issue of a color filter, is inferior.
Therefore, some color filters using a pigment as a coloring agent have been proposed, among which are an electrodeposition method, a printing method, and a photolithography method (photolithography method).

However, the electrodeposition method requires the formation of an electrode pattern. (1) The degree of freedom of the pattern is small.
(2) The cost is high, and the printing method has problems such as (1) it is difficult to align a large substrate and the resolution is low, so it is difficult to cope with miniaturization, and (2) the flatness of the pattern is poor. The photolithography method is considered to be the mainstream. The photolithography method includes a liquid resist method and a film transfer method. In the liquid resist method, a varnish in which a pigment is dispersed in a photosensitive resin is applied on a glass substrate by a spinner, dried, exposed, and developed to form color pixels. On the other hand, in the film transfer method, a varnish is formed into a film in the same manner as a photosensitive film for a printed board. After lamination on a substrate, color pixels are formed by exposure and development.

Film transfer method The photosensitive element used in the color filter manufacturing method includes a three-layer structure of (1) a support film, (2) a photosensitive resin layer, (3) a cover film, and (1) a support. A four-layer structure of a film, (2) a cushion layer, (3) a photosensitive resin layer, (4) a cover film, or a five-layer structure having an intermediate layer between the cushion layer and the photosensitive resin layer is proposed. Have been.

These are used alone or in combination of two or more. Such a solvent has a solid content of 10% in the photosensitive composition.
Preferably, it is used in such an amount that it becomes ６０60% by weight. If the amount is too large, the dispersion stability tends to decrease, and if the amount is too small, gelation tends to occur.

A polymerization inhibitor can be added to the photosensitive liquid for a color image forming material (photosensitive composition) of the present invention in order to prevent a dark reaction. As the polymerization inhibitor, for example,
Hydroquinone, P-methoxyphenol, 2,6-di-t-butyl-p-cresol, 2,2′-methylenebis (4-methyl-6-t-butylphenol), cuperone, and the like. The compound is preferably used in an amount of 0.001 to 1% by weight based on the total solid content in the photosensitive solution as the color filter material of the present invention.
More preferably, it is used at 0.5% by weight. If the amount is too small, the polymerization inhibitor is ineffective, and if it is too large, the sensitivity is lowered.

As a support for applying a photosensitive composition dissolved in a diluent or a solvent for forming a colored image, for example, for a color filter, a transparent glass plate, that is, a blue plate glass, mainly non-alkali, Aluminosilicate, quartz glass and the like are used. For other uses, an acrylic resin plate, a vinyl chloride resin plate, a copper plate, an aluminum plate, a nickel plate, a metal plate of stainless steel or the like is used.

Examples of the coating method include roll coater coating, spin coater coating, spray coating, wool coater coating, dip coater coating, curtain flow coater coating, wire bar coater coating, gravure coater coating, and air knife coater coating. After coating the photosensitive composition on these supports by the above-mentioned method, the photosensitive composition is naturally dried or forcibly dried by heating to form a dried coating film of several μm.

Instead of coating directly on the permanent support, it is possible to form a film on the permanent support by coating on the support to form a photosensitive element and then laminating. This method is effective when the coating cannot be applied directly to the permanent support. As a method of applying to the support film,
It can be performed by the method described in the above-mentioned coating method.

The photosensitive element preferably has a four-layer structure in which a support film, a cushion layer, a photosensitive resin layer, and a cover film are sequentially laminated. The film as the photosensitive composition is left on the support, and the cushion layer can be peeled off. After peeling off the support film and the cushion layer, the active light is irradiated imagewise through a photomask or the like, and the exposed portion is exposed. Is cured by light, and the unexposed portions are removed by development, whereby a colored image can be formed on the permanent support. This prevents a transfer failure and a decrease in image flatness due to unevenness due to pixels or a black matrix on the already formed permanent support during transfer of the photosensitive resin layer, and prevents the cushion layer from being colored. It is possible to obtain a color filter having good pixel flatness after development, since the layer is sufficiently peeled off.

As the support film, a film which is chemically and thermally stable and can be formed into a sheet or plate can be used. Specifically, polyethylene, polyolefin such as polypropylene, polyvinyl chloride, polyvinyl halide such as polyvinylidene chloride, cellulose acetate, nitrocellulose, cellulose derivatives such as cellophane, polyamides, polystyrene, polycarbonate, polyimides. . Among them, particularly preferred is biaxially oriented polyethylene terephthalate having excellent dimensional stability and permeability. The thickness of the support film is 6-1.
00 μm is preferred. When the thickness is 6 μm or less, the surface roughness of a laminating roll or the like during lamination is adjusted to a cushion layer as a base,
This is because the surface of the film as a photosensitive composition may be roughened after being transferred to the colored photosensitive resin layer.

The cushion layer can be formed into a sheet.
No stickiness at room temperature, with a smoothness of 0.05 as a film
μm or less is desirable. In addition, the hardness at the temperature at which a colored photosensitive resin film is laminated on a transparent substrate (JIS)
K6301) is preferably 80 degrees or less. The reason for this is that if the hardness is too high, pressure does not penetrate into the edges of the image pattern formed on the transparent substrate, bubbles enter, the thickness of the photosensitive layer transferred to the edges increases, and the formed image becomes flat. This is because the property is impaired. The thickness of this layer is desirably greater than the thickness of the photosensitive resin layer,
Double the thickness is required. The thickness of the photosensitive resin layer is 1.5μ
In the case of m, the thickness is preferably 3 μm or more.

In order to exhibit good releasability from the photosensitive resin layer after transfer, a material having low adhesion to the photosensitive resin layer is used for the cushion layer, or an interface between the colored photosensitive resin film and the cushion layer is used. A release treatment may be performed by, for example, applying a silicon compound or the like to the film. In addition, the cushion layer may be coated on the support film in advance, and may be bonded to the photosensitive resin layer to reduce the adhesive strength with the cushion layer.

Materials used for the cushion layer include polyolefins such as polyethylene and polypropylene, ethylene and vinyl acetate, ethylene and acrylate, ethylene copolymers such as ethylene and vinyl alcohol, polyvinyl chloride, and vinyl chloride and vinyl acetate. Copolymer of vinyl chloride and vinyl alcohol, polyvinylidene chloride, polyvinylidene chloride copolymer, polystyrene, styrene copolymer such as styrene and (meth) acrylate, polyvinyl toluene, vinyl toluene and (meth) acrylic acid Selected from vinyl toluene copolymers such as esters, poly (meth) acrylates, copolymers of (meth) acrylates such as butyl (meth) acrylate and vinyl acetate, synthetic rubbers, cellulose derivatives, etc. At least one It is possible to use an organic polymer above.

As the cover film of the photosensitive element of the present invention, a film which is chemically and thermally stable and which can be easily separated from the photosensitive layer is desirable. Specifically, a thin sheet made of polyethylene, polypropylene, polyethylene terephthalate, polyvinyl alcohol or the like and having high surface smoothness is preferable. It also includes those whose surface has been subjected to release treatment to impart releasability.

As a method of laminating the photosensitive resin layer obtained on the support film to the permanent support, it is more preferable to peel off the cover film and heat-press the cover film on the permanent support, because the adhesion is improved, and it is more preferable. .

The thickness of the photosensitive composition in the method formed on the surface of the permanent support in this way is determined depending on the application, but is usually in the range of 0.1 to 500 μm. 0.1 to 5μ when used for liquid crystal color filters
m.

The photosensitive resin layer, which is a dried coating film, is exposed with an exposing machine to cure the photosensitive portion. Exposure machines that can be applied to the composition of the present invention include a carbon arc lamp,
Examples include an ultra-high pressure mercury lamp, a high pressure mercury lamp, a xenon lamp, a metal halide lamp, a fluorescent lamp, a tungsten lamp and the like.
