Description

감광성수지 조성물 및 컬러필터{PHOTOSENSITIVE RESIN COMPOSITION AND COLOR FILTER} Photosensitive resin composition and color filter {PHOTOSENSITIVE RESIN COMPOSITION AND COLOR FILTER}             

본 발명은 컬러필터 제조용 감광성 수지 조성물에 관한 것으로, 더욱 상세하게는 카도계 바인더 수지와 분자량이 상이한 두 종류의 아크릴계 광중합성 모노머를 포함하는 것을 특징으로 하는 패턴모양 및 현상성이 우수한 알카리수용액 현상형 감광성 수지조성물 및 그로부터 제조되는 컬러필터에 관한 것이다. The present invention relates to a photosensitive resin composition for producing a color filter, and more particularly, an alkaline aqueous solution developing type having excellent pattern shape and developability, comprising a cardo binder resin and two kinds of acrylic photopolymerizable monomers having different molecular weights. It relates to a photosensitive resin composition and a color filter produced therefrom.

컬러필터는 액정표시장치, 카메라의 광학필터 등에 사용되는 것으로서, 일반적으로 플라스틱, 또는 유리로 된 기판 상부에 블랙매트릭스와 적, 녹, 청의 삼색의 착생층이 반복되며, 그 위에 오버코트층(OVERCOAT)과 ITO(Indium Thin Oxide) 투명전도막층이 차례로 적층되어 구성된다.Color filters are used in liquid crystal displays, optical filters in cameras, and the like. In general, black matrix and three color layers of red, green, and blue are repeated on a plastic or glass substrate, and an overcoat layer is formed thereon. And an indium thin oxide (ITO) transparent conductive film layer are sequentially stacked.

이와 같은 컬러필터는 염색법, 인쇄법, 안료분산법, 전착법 등의 방법에 의하여 제조된다. Such color filters are manufactured by methods such as dyeing, printing, pigment dispersion, and electrodeposition.

염색법의 경우에는 기판상에 미리 젤라틴 등의 천연감광성수지, 아민 변성 폴리비닐알코올, 아민 변성 아크릴수지 등의 염색 기재를 가진 화상을 형성시킨 후 직접염료 등의 염료로 염색하여 제작하지만, 다색을 동일 기판상에 형성시킬 필요가 있기 때문에 색상을 변화시킬때마다 방염가공을 할 필요가 있는 등 공정이 매우 복잡하고 긴 문제점을 갖고 있다. 또한 일반적으로 사용하는 염료 및 수지 자체의 선명성 및 분산성 등은 좋으나 내광성, 내습성 및 컬러필터의 가장 중요한 성질인 내열성이 나쁜 단점이 있다. 예컨대, 대한민국 특허공고 제 91-4717호와 대한민국 특허공고 제 94-7778호에는 염료로서 아조화합물과 아지드화합물을 사용하는 것이 개시되어 있지만, 전술한 바와 같이 안료형에 비하여 내열성 및 내구성이 떨어지는 단점을 갖는다.In the dyeing method, an image having a dye-based base material such as natural photosensitive resin such as gelatin, amine-modified polyvinyl alcohol, amine-modified acrylic resin, etc. is formed on the substrate before dyeing with dyes such as direct dyes. Since it needs to be formed on a substrate, the process is very complicated and has a long problem, such as the need to perform flameproof processing every time the color is changed. In addition, although the sharpness and dispersibility of the dyes and resins used in general are good, there are disadvantages in light resistance, moisture resistance, and heat resistance, which is the most important property of the color filter. For example, Korean Patent Publication No. 91-4717 and Korean Patent Publication No. 94-7778 disclose the use of an azo compound and an azide compound as dyes. However, as described above, heat resistance and durability are inferior to pigment type. Has

인쇄법은 열경화 또는 광경화수지에 안료를 분산시킨 잉크를 사용하고, 인쇄를 행한 후 열 또는 광으로 경화시켜 제조하므로, 다른 방법에 비해 사용되는 재료비의 절감을 가져올 수는 있지만, 고도로 정밀하고 세밀한 화상 형성이 곤란하고, 또한 형성되는 박막층이 균일하지 못한 단점이 있다. 예컨대, 대한민국 특허공개 제 95-703746호, 대한민국 특허공개 제 96-11513호에서는 잉크젯 방식을 이용한 컬러필터의 제조방법을 제안하고 있다. 그러나, 섬세하고 정확한 색조의 인쇄를 위하여 노즐에서 분사되는 칼라레지스트 조성물이 염료형으로 되어 있기 때문에 염색법과 마찬가지로 내구성 및 내열성이 떨어지게 된다.The printing method uses ink in which pigment is dispersed in thermosetting or photocuring resin, and is manufactured by printing and curing by heat or light, so that the material cost can be reduced compared to other methods, but it is highly precise and It is difficult to form fine images, and there is a disadvantage that the thin film layer formed is not uniform. For example, Korean Patent Publication No. 95-703746 and Korean Patent Publication No. 96-11513 propose a method of manufacturing a color filter using an inkjet method. However, since the color resist composition sprayed from the nozzle is dye-type for printing of fine and accurate color tone, durability and heat resistance are inferior as in the dyeing method.

한편, 대한민국 특허공개 제 93-700858호, 및 대한민국 특허공개 제 96-29904호에서는 전기침전법을 이용한 전착법을 제안하고 있는데, 전착법은 정밀한 착색망을 형성할 수 있고 안료를 사용하므로 내열성 및 내광성이 우수한 특성을 가지고 있으나, 화소 크기가 정밀하게 되어 전극 패턴이 세밀하게 되면 양쪽 끝에 전 기저항으로 인한 착색 얼룩이 나타나거나 착색막 두께가 두꺼워져 고도의 정밀성을 요구하는 컬러필터에 적용하기 곤란한 한계가 있다.Meanwhile, Korean Patent Publication No. 93-700858 and Korean Patent Publication No. 96-29904 propose an electrodeposition method using an electroprecipitation method, which is capable of forming a precise colored network and uses pigments, thereby providing heat resistance and It has excellent light resistance, but when the pixel size is precise and the electrode pattern is fine, it is difficult to apply it to color filters that require high precision due to the appearance of color unevenness due to electric resistance at both ends or thick film thickness. There is.

안료분산법은 블랙매트릭스가 제공된 투명한 기질 위에 착색제를 함유하는 광중합성 조성물을 코팅하고, 형성하고자 하는 형태의 패턴을 노광한 후 비노광부위를 용제로 제거하여 열경화시키는 일련의 단계를 반복함으로써 컬러필터를 제조하는 방법이다. 이러한 안료분산법은 컬러필터의 가장 중요한 성질인 내열성 및 내구성을 향상시키며 필름의 두께를 균일하게 유지시킬 수 있다는 장점을 가지고 있어 블랙매트릭스의 제조에 많이 이용되고 있다. 예컨대, 대한민국특허공개 92-702502호, 대한민국 특허공고 제 94-5617호, 대한민국 특허공고 제 95-11163호, 대한민국 특허공개 제 95-700359호에는 안료분산을 이용한 칼라레지스트의 제조방법이 제안되어 있다.The pigment dispersion method is a color filter by coating a photopolymerizable composition containing a colorant on a transparent substrate provided with a black matrix, exposing the pattern of the form to be formed, and then repeating a series of steps of removing the non-exposed areas with a solvent and thermal curing. It is a method of manufacturing. The pigment dispersion method is used in the manufacture of the black matrix has the advantage of improving the heat resistance and durability, which is the most important property of the color filter and maintaining the thickness of the film uniformly. For example, Korean Patent Publication No. 92-702502, Korean Patent Publication No. 94-5617, Korean Patent Publication No. 95-11163, and Korean Patent Publication No. 95-700359 propose methods for producing color resists using pigment dispersion. .

안료분산법에 의해 제조되는 블랙매트릭스는 크게 지지체 역할 및 일정 두께의 유지를 가능하게 하는 고분자화합물, 즉 바인더수지와 노광시 광과 반응하여 포토레지스트상을 형성하는 광중합성 모노머의 2 가지 성분으로 구성되고, 상기한 성분 이외에 안료, 중합개시제, 에폭시수지, 용제와 기타 첨가제 등을 포함하는 감광성 수지 조성물에 의해 제조된다. 안료분산법에 사용되는 바인더수지로는 예컨대, 일본특개소 60-237403호에 개시된 감광성 폴리이미드수지, 일본특개평 1-200353호, 동 평4-7373호, 동 4-91173호 등에 기재된 아크릴계중합체와 아지드 화합물로 이루어진 감광성수지, 일본특개평 1-152449호에 기재된 아크릴레이트 단량체, 유기중합체 결합제, 및 광중합개시제로 이루어진 라디칼 중합형의 감광성 수 지, 일본특개평 4-163552호와 대한민국특허 공보 제 92-5780호에 개시된 페놀수지, N-메틸올 구조를 갖는 가교제 및 광산발생제로 이루어진 감광성수지 등의 여러 가지가 제안되어 있다. The black matrix produced by the pigment dispersion method is composed of two components, a polymer compound that largely supports the role of a support and maintains a constant thickness, that is, a binder resin and a photopolymerizable monomer that reacts with light during exposure to form a photoresist image. And a photosensitive resin composition containing a pigment, a polymerization initiator, an epoxy resin, a solvent and other additives, etc., in addition to the above components. As the binder resin used in the pigment dispersion method, for example, the photosensitive polyimide resin disclosed in Japanese Patent Application Laid-Open No. 60-237403, Japanese Patent Application Laid-Open No. 1-200353, Japanese Patent Application No. 4-7373, Japanese Patent Application No. 4-91173 and the like Photosensitive resin consisting of azide compound and radical polymerization type photosensitive resin consisting of acrylate monomer, organic polymer binder, and photoinitiator described in Japanese Patent Laid-Open No. 1-152449, Japanese Patent Laid-Open No. 4-163552, and Korean Patent Publication Various photosensitive resins, such as a phenol resin disclosed in US Pat. No. 92-5780, a crosslinking agent having an N-methylol structure and a photoacid generator, have been proposed.

그러나, 안료분산법에 따른 바인더수지로서 감광성 폴리이미드나 페놀계의 수지를 사용하는 것은 내열성은 높지만 감도가 낮으며 유기용매로 현상해야하는 등의 결점이 있다. 또한 아지드 화합물을 감광제로 하는 종래의 시스템은 감도가 낮고 내열성이 떨어지거나 노출시에 산소의 영향을 받는 문제가 있다. 이러한 문제점을 극복하기 위해 산소차단막을 설치하거나 불활성 가스중에 노출시키는 방법이 이용될 수 있으나, 이러한 방법을 적용하는 경우에는 공정이 복잡해지고 장치가 비싸지는 등의 문제가 있다. 또한 노출로 인해 생성된 산을 이용하여 화상을 형성하는 감광성수지는 고감도이며 노출될 때 산소의 영향을 받지 않는 이점이 있지만, 노출과 현상하는 과정에서 가열공정이 필요하며 가열시간이 패턴 형성에 대해 민감한 반응을 보이므로 공정관리가 어려운 단점이 있다.However, the use of photosensitive polyimide or phenolic resins as binder resins according to the pigment dispersion method has disadvantages such as high heat resistance but low sensitivity and development with an organic solvent. In addition, conventional systems using azide compounds as photosensitizers have problems of low sensitivity, poor heat resistance, and effects of oxygen upon exposure. In order to overcome this problem, a method of installing an oxygen barrier film or exposing it to an inert gas may be used. However, in the case of applying such a method, a process is complicated and an apparatus is expensive. In addition, the photosensitive resin which forms an image using the acid generated by the exposure has a high sensitivity and has the advantage of not being affected by oxygen when exposed, but a heating process is required in the process of exposure and development, and a heating time is required for pattern formation. Because of the sensitive reaction, process control is difficult.

이러한 문제를 해결하기 위해 일본특개평 7-64281호, 동7-64282호, 동8-278630호, 동6-1938호, 동5-339356호, 대한민국 특허공개 95-702313호에는 카도계바인더수지를 이용한 컬러필터의 제조방법을 개시하고 있다. 일반적으로 카도계를 지닌 수지는 고감도이면서 산소의 영향을 받지 않고 내열성, 내수축성, 내화학성 등이 우수하다. 그러나, 감광성 수지 조성물 자체내에 알칼리 현상 수용액과 반응할 장소가 없기 때문에 현상성이 나빠져서 현상후 잔사가 남는 경우가 많다. 이러한 경우 현상성을 높이기 위해 일본국 특개평 4-363311호에서는 카도계의 바인 더수지를 산무수물로 처리하여 알카리 용해성 수지로 만들므로써 현상성의 향상을 꾀하였다. 그러나 이러한 처리 후에도 현상시간이 길어지거나 현상후 잔사가 많이 남아 있을 경우가 많은데 이것은 알카리 수용액에 잘 녹지 않는 성분들에 기인한다. 잘 녹지 않는 성분 중의 대표적인 것으로는 광중합을 일으키기 위해 첨가하는 광중합성 모노머가 있는데, 광중합성 모노머의 종류에 따라 현상성이 많이 차이난다.In order to solve this problem, Japanese Patent Laid-Open Nos. 7-64281, 7-64282, 8-278630, 6-1938, 5-339356, and Korean Patent Publication No. 95-702313 disclose a cardo binder binder resin. Disclosed is a method of manufacturing a color filter using. In general, a resin having a cardo-based resin is highly sensitive and is not affected by oxygen, and is excellent in heat resistance, shrinkage resistance, and chemical resistance. However, since there is no place to react with alkali developing aqueous solution in the photosensitive resin composition itself, developability worsens and the residue after image development often remains. In this case, Japanese Patent Application Laid-Open No. 4-363311 improves developability by treating the Kado-based Vine resin with an acid anhydride to make an alkali soluble resin. However, even after such treatment, the development time is long or a lot of residues remain after development, which is attributable to components that are not easily dissolved in an aqueous alkali solution. Typical examples of the poorly soluble components are photopolymerizable monomers added to cause photopolymerization, and developability varies greatly depending on the type of photopolymerizable monomer.

본 발명자는 적절한 광중합반응을 일으켜 컬러필터에 적합한 패턴을 형성하고 현상성을 향상시켜 현상시간을 단축하고 잔사를 획기적으로 줄일 수 있는 방법을 모색한 결과 분자량이 상이한 광중합성 모노머를 첨가함으로써 상기의 목적을 달성할 수 있음을 발견하고 본 발명을 성안하게 되었다.The inventors of the present invention have found that a suitable photopolymerization reaction can be performed to form a pattern suitable for a color filter, improve the developability, shorten the development time and significantly reduce the residue, thereby adding a photopolymerizable monomer having a different molecular weight. It has been found that the present invention can be achieved and the present invention has been devised.
