Description

옥심 에스터 화합물, 이를 포함하는 감광성 조성물 및 용도{Oxim ester compounds, photosensitive composition comprising the same and usage}Oxim ester compounds, photosensitive composition comprising the same and usage

본 발명은 감광성 조성물에서 광개시제로 유용한 옥심 에스터 화합물, 이를 포함하는 감광성 조성물과 그 용도에 관한 것이다. The present invention relates to oxime ester compounds useful as photoinitiators in photosensitive compositions, to photosensitive compositions comprising them and to their use.

옥심 유도체는 광개시제로 유용하며, 그 일예로 국제특허 공개 WO02/100903 A1에는 옥심 에스터기를 가진 광개시제에 관해 기재되어 있으며, 여기에는 광개시제로 사용될 수 있는 다양한 옥심 에스터 화합물의 구조와 합성에 대해 상세히 기재되어 있다. 여기에 기재된 옥심 에스터 화합물의 일반적인 광 분해 반응은 반응식 1과 같다.Oxime derivatives are useful as photoinitiators and, for example, in WO02 / 100903 A1, describe photoinitiators with oxime ester groups, which are described in detail for the structure and synthesis of various oxime ester compounds that can be used as photoinitiators. have. The general photolysis reaction of the oxime ester compound described herein is shown in Scheme 1.

(One)

이러한 옥심 에스터기를 갖는 광개시제는 광반응에 의하여 이미닐 라디칼과 알킬라디칼 두 종류를 생성하며 두 종류 모두 라디칼 반응에 참여한다. 또한 여기 상태에서 분해 반응이 매우 빠르므로 공기 중의 산소에 대한 영향이 적다. Such photoinitiators having an oxime ester group generate two kinds of imineyl radicals and alkyl radicals by photoreaction, and both of them participate in radical reactions. In addition, since the decomposition reaction is very fast in the excited state, there is little effect on the oxygen in the air.

공기 중의 산소에 대한 영향이 적다는 것은 일반적인 칼라필터용 포토레지스트의 사용에서 요구되는 매우 중요한 특성 중 하나인데, 칼라필터용 포토레지스트를 패터닝할 때 포토마스크를 코팅 막과 약간의 거리를 두기 때문에(proximity exposure) 상당한 공기가 표면에 존재하고 있기 때문이다. The small effect on the oxygen in the air is one of the very important characteristics required for the use of color filter photoresists in general, because the photomask is slightly distanced from the coating film when patterning the color filter photoresist ( proximity exposure) because significant air is present on the surface.

상기 반응식 1에 나타낸 것과 같은 옥심 에스터 화합물의 R, R', R"의 치환기를 적당히 조절함으로써 개시제의 흡수대도 조절할 수 있을 뿐만 아니라 삼중항 증감효과(triplet sensitization)도 얻을 수 있다. By suitably adjusting the substituents of R, R ', and R "of the oxime ester compound as shown in Scheme 1, the absorption band of the initiator can be adjusted as well as triplet sensitization can be obtained.

특히 상기의 옥심 에스터 화합물 중에서도 반응식 1에서 보여지는 것과 같은 광분해 반응에 따라 생성된 알킬 라디칼이 메틸 라디칼(CH3ㅇ)이거나 페닐 라디칼 (C6H5ㅇ)인 경우에 다른 치환기 보다 광 반응 속도가 높은 것으로 알려져 있다. 이는 메틸이나 페닐 라디칼이 다른 라디칼 보다 반응 속도가 높기 때문으로 이해되고 있다.Particularly, among the above oxime ester compounds, the photoreaction rate is higher than that of other substituents when the alkyl radical produced by the photolysis reaction as shown in Scheme 1 is a methyl radical (CH 3 ㅇ) or a phenyl radical (C 6 H 5 ㅇ). It is known to be high. It is understood that the methyl or phenyl radicals have a higher reaction rate than other radicals.

그러나 메틸이나 페닐 라디칼을 발생하는 옥심 에스터 광개시제의 경우 감광성 수지 조성의 용제로 주요하게 사용되고 있는 프로필렌글리콜모노메틸에테르아세테이트(이하, PGMEA라 함)에는 약 0.75% 정도의 용해도를 가지며 메틸에틸카비톨(이하, MEC라 함)에는 1.2% 정도의 용해도를 보여 그 사용에 제한이 된다. 즉, 사 용되는 바인더가 광개시제와 상용성이 떨어질 경우 상분리에 의한 백화 현상이 나타난다. However, the oxime ester photoinitiator which generates methyl or phenyl radical has a solubility of about 0.75% in propylene glycol monomethyl ether acetate (hereinafter referred to as PGMEA), which is mainly used as a solvent for the photosensitive resin composition. In the following, MEC) shows a solubility of about 1.2%, which limits its use. That is, when the binder used is incompatible with the photoinitiator, a whitening phenomenon due to phase separation appears.

결국 광개시제의 용제에 대한 용해성 부족은 다양한 종류의 바인더나 다기능성 모노머를 사용한 광 가교반응을 이용하는 감광성 조성 시스템에서는 큰 제약 조건이다.As a result, the lack of solubility in solvents of photoinitiators is a significant constraint in photosensitive composition systems using photocrosslinking reactions using various types of binders or multifunctional monomers.

한편 대한민국 특허 공개 제2007-0027446호에는 상기한 옥심 에스터 화합물 중에서도 카바졸 또는 그 치환체를 갖는 아실옥심에스터 화합물을 광개시제로 함유하는 감광성 조성물에 대해 기재되어 있는데, 이 경우 양호한 직선성을 가지고 벗겨지기 어려우며 잔사가 적은 블랙 매트릭스 패턴을 형성할 수 있는 것으로도 기재되어 있다. Meanwhile, Korean Patent Publication No. 2007-0027446 discloses a photosensitive composition containing an acyl oxime ester compound having a carbazole or a substituent thereof as a photoinitiator among the oxime ester compounds, in which case it is difficult to peel off with good linearity. It is also described as being able to form a black matrix pattern with few residues.

5) AcCl, Et3N이다.5) AcCl, Et 3 N.

이를 구체적으로 살피면, 하이드록시 에틸 카바졸 (1)과 알킬 할라이드 (R-X)를 NaH를 염기로 사용하여 반응시켜 알킬 에테르가 결합된 카바졸 (2)을 합성하고 아릴카르보닐 클로라이드와 알루미늄 클로라이드를 이용하여 아릴 카르보닐 기를 카바졸 링에 도입하고 아세틸 클로리드를 다시 한 번 더 프리델 크래프트 반응시켜 카바졸의 링의 각각에 카르보닐기가 치환된 화합물 (4)을 합성한다. 화합물 (4)와 +NH3OHㅇ-OAc를 에탄올에서 순환증류시키면 반응성이 높은 아세틸기와 반응하여 옥심 화합물(5)이 생성된다. 생성된 옥심 화합물 (5)과 아세틸 클로라이드를 반응시키면 원하는 옥심 에스터기를 갖는 카바졸 광개시제를 얻을 수 있다. Specifically, hydroxyethyl carbazole ( 1 ) and alkyl halide (RX) are reacted using NaH as a base to synthesize an alkyl ether-bound carbazole ( 2 ), using arylcarbonyl chloride and aluminum chloride. The aryl carbonyl group is introduced into the carbazole ring, and acetyl chloride is once again subjected to Friedel craft reaction to synthesize compound ( 4 ) in which the carbonyl group is substituted in each of the rings of carbazole. Cyclic distillation of compound ( 4 ) and + NH 3 OH - OAc in ethanol reacts with highly reactive acetyl group to give oxime compound ( 5 ). By reacting the produced oxime compound ( 5 ) with acetyl chloride, a carbazole photoinitiator having a desired oxime ester group can be obtained.

또 다른 본 발명에 따른 옥심 에스터 화합물은 상기 화학식 2로 표시되는 것과 같이 카바졸기의 질소원자에 에스터 치환체를 갖는 화합물이다. 화학식 2로 표시되는 화합물에 있어서 R4은 C1-C12의 선형 또는 분지형 알킬기, C3-C8의 사이클로알킬기,

In particular, when R 4 is a substituent having an acryl group capable of radical reaction, it is more compatible with the binder in the photosensitive composition, and the matrix is reacted with the crosslinking agent to minimize leakage of carbazole derivatives generated as a byproduct after the photoreaction. R 4 is an additional advantage

An example of the synthesis of an oxime ester having an ester bond represented by Formula 2 is shown in Scheme 3 below.

반응식 3에 의거 살피면, 하이드록시 에틸카바졸을 트리에틸 아민 존재하에 서 아세틸 클로라이드와 반응시켜 아세테이트 (7)로 치환시킨다. 알콜기가 보호된 카바졸을 상기한 반응식 2에서와 같이 프리델-크라프트 반응을 통하여 카바졸 양쪽 링에 아릴 카르보닐과 아세틸기가 치환된 화합물 (8)을 합성한다. 화합물 (8)과 +NH3OHㅇ-OAc를 에탄올에서 순환 환류시키면 에스테르 결합으로 치환된 아세테이트는 분리되어 알콜기로 바뀌며 아세틸기가 옥심으로 동시에 변환되어 화합물 (9)을 얻는다. 옥심 (9)의 OH기가 알콜의 OH 보다 반응성이 높으므로 1당량의 AcCl을 트리에틸아민 존재 하에 반응시켜 옥심 에스터로 바꾼 뒤 이를 분리하지 않고 두 번째 알킬 카르보닐 클로리드를 첨가하여 목적하는 에스터기가 측쇄에 치횐된 옥심 에스터 (11)을 얻는다. 이 반응에서 약 5% 정도의 혼합물이 생성되지만 광개시제의 성능에는 문제가 없다. In accordance with Scheme 3, hydroxy ethylcarbazole is reacted with acetyl chloride in the presence of triethyl amine and replaced with acetate ( 7 ). Synthesizes the craft through the reaction carbazole group in both rings arylcarbonyl and acetyl-substituted compound (8) alcohol groups, as shown in the above Scheme 2, the protected carbazole Friedel. Cyclic reflux of compound ( 8 ) and + NH 3 OH - OAc in ethanol separates the acetate substituted by ester linkage, converts to alcohol group, and converts acetyl group to oxime simultaneously to obtain compound ( 9 ). Since the OH group of oxime ( 9 ) is more reactive than the OH of alcohol, one equivalent of AcCl is reacted in the presence of triethylamine to be converted into an oxime ester, and then, without separation, a second alkyl carbonyl chloride is added to the desired ester group. Obtained oxime ester 11 in the side chain is obtained. This reaction produces about 5% of the mixture, but there is no problem with the performance of the photoinitiator.

The oxime ester compound represented by the formula (1) or (2) does not affect the photolysis reaction and improves solubility, in particular, solubility in alkylene glycol monoalkyl ether acetates such as PGMEA, which is the main solvent of the photosensitive composition, or ethers such as MEC, etc. Ultimately, whitening in the thin film after coating can be improved.

According to the present invention, there is provided a substrate having a column spacer, a black matrix, a color filter, a substrate having an organic insulating film, and a film formed by coating the same from the photosensitive resin composition, wherein the film is a word processor, a computer, a television or a plasma display panel, Surface of polarizing plate used in liquid crystal display, sunglasses lens, eyeglass lens with frequency, finder lens for camera, cover of instrument, glass of automobile, glass of tank, brightness enhancement film, or waveguide film have.

감광성 조성물을 사용하여 패턴을 형성하는 방법으로는, 기판 또는 기판 상에 감광성 수지 조성물을 도포하고, 도포된 감광성 조성물층으로부터 용제 등 휘발 성분을 제거하고, 포토마스크를 통해 휘발 성분이 제거된 층을 노광한 후 현상하는 방법을 들 수 있다. As a method of forming a pattern using the photosensitive composition, a photosensitive resin composition is applied onto a substrate or a substrate, a volatile component such as a solvent is removed from the applied photosensitive composition layer, and a layer from which the volatile component is removed through a photomask is removed. The method of developing after exposure is mentioned.

기판으로는 예를 들면 유리 기판, 실리콘 기판, 폴리카보네이트 기판, 폴리에스터 기판, 방향족 폴리아미드 기판, 폴리아미드이미드 기판, 폴리이미드 기판, 알루미늄 기판, GaAs 기판 등의 표면이 평탄한 기판 등을 들 수 있다. As a board | substrate, the board | substrate with flat surfaces, such as a glass substrate, a silicon substrate, a polycarbonate board | substrate, a polyester board | substrate, an aromatic polyamide board | substrate, a polyamideimide board | substrate, a polyimide board | substrate, an aluminum substrate, GaAs board | substrate, etc. are mentioned, for example. .

기판 위에 감광성 수지 조성물을 도포하는 방법으로는 그 한정이 없으나, 일예로 스핀 코팅법, 캐스팅법, 롤 도포법, 슬릿 & 스핀 코팅법, 스핀리스 코터 등의 코터를 사용하여 도포하는 등의 공지된 도포 방법 등으로 기판 등 위에 도포할 수 있다. The method of coating the photosensitive resin composition on the substrate is not limited, but is known, for example, by coating using a coater such as spin coating, casting, roll coating, slit & spin coating, or spinless coater. It can apply | coat on a board | substrate etc. by a coating method.

이어서 용제 등의 휘발 성분을 가열에 의해 휘발시킬 수 있다. 이와 같이하여 기판 등의 위에 감광성 조성물의 고형분으로 이루어진 층이 형성된다. 그 다음 감광성 조성물의 고형분으로 이루어진 층을 노광하는데, 예를 들면 포토마스크를 통해 선택적으로 활성 에너지선을 조사할 수 있다. 노광 광원으로는 통상 저압 수은등, 중압 수은등, 고압 수은등, 초고압 수은등, 크세논 램프, 금속 할로겐 램프 등이 적당하다. 또한 레이저 광선 등도 노광용 활성 에너지선으로 사용할 수 있다. 그밖에 전자선, α선, β선, γ선, X선, 중성자선 등도 사용 가능하다. 활성 에너지선은 포토마스크를 통해 조사되며, 여기서 포토마스크는 예를 들면 유리판 표면에 활성 에너지선을 차페하는 차광층이 설치된 것이다. 유리판 중의 차광층이 설치되지않은 부분은 활성 에너지선이 투과하는 투광부이며, 이 투광부의 패턴에 따른 패턴으로 감광성 조성물이 노광되어 활성 에너지선이 조사되지 않은 미조사 영역과 활성 에너지선이 조사된 조사 영역이 생긴다. Subsequently, volatile components, such as a solvent, can be volatilized by heating. In this way, the layer which consists of solid content of the photosensitive composition is formed on substrates etc. The layer of solids of the photosensitive composition is then exposed, for example an active energy ray can be selectively irradiated through a photomask. As an exposure light source, a low pressure mercury lamp, a medium pressure mercury lamp, a high pressure mercury lamp, an ultra high pressure mercury lamp, a xenon lamp, a metal halogen lamp etc. are suitable normally. Moreover, a laser beam etc. can also be used as an active energy ray for exposure. In addition, electron beams, α rays, β rays, γ rays, X rays, neutron rays and the like can also be used. The active energy ray is irradiated through the photomask, where the photomask is provided with a light shielding layer for shielding the active energy ray, for example, on the surface of the glass plate. The part where the light shielding layer is not provided in the glass plate is a light transmitting part through which active energy rays are transmitted. An irradiation area is created.

이와 같이 노광을 행한 기판은 일예로 묽은 알칼리 수용액으로 현상한다. 현상하는 데는 예를 들면 노광 후의 감광성 조성물층을 묽은 알칼리 수용액과 접촉시킬 수 있고 구체적으로는 그 표면 상에 감광성 조성물층이 형성된 상태의 기판을 묽은 알칼리 수용액에 침지하거나 묽은 알칼리 수용액을 샤워 형태로 내뿜을 수 있다. 묽은 알칼리 수용액으로서는 예를 들면 탄산나트륨, 탄산칼륨, 수산화나트륨, 수산화칼륨, 테트라메틸암모늄하이드록사이드, 유기 아민 등의 알칼리성 화합물의 수용액 등을 들 수 있다. 현상에 의해서 감광성 조성물층 중의 활성 에너지선이조사되지 않은 미조사 영역은 제거된다. 한편 활성 에너지선 조사 영역은 그대로 남아 패턴을 구성한다. In this way, the exposed substrate is developed with diluted alkali aqueous solution. For example, the photosensitive composition layer after exposure can be brought into contact with a diluted alkali aqueous solution. Specifically, the substrate in which the photosensitive composition layer is formed on the surface thereof is immersed in the diluted alkaline aqueous solution or the diluted alkaline aqueous solution is flushed out in the form of a shower. Can be. As dilute aqueous alkali solution, aqueous solution of alkaline compounds, such as sodium carbonate, potassium carbonate, sodium hydroxide, potassium hydroxide, tetramethylammonium hydroxide, an organic amine, etc. are mentioned, for example. The unirradiated area | region to which the active energy ray was not irradiated in the photosensitive composition layer is removed by image development. On the other hand, the active energy ray irradiation area remains as it is and constitutes a pattern.

이와 같이 현상을 행한 기판은 통상적으로 수세하여 건조시킴으로써 목적하는 패턴을 얻을 수 있다. The substrate which has been developed in this manner can be washed with water and dried, thereby obtaining a desired pattern.

이와 같은 일련의 패턴 형성 과정은 칼럼 스페이서, 블랙 레지스트, 칼라 레지스트 등의 형성에서 대동소이하다. This series of pattern formation processes are almost the same in the formation of column spacers, black resists, color resists, and the like.

상기 실시예 및 비교예서 사용된 광개시제의 PGMEA에 대한 용해성, 이들로부터 조액된 블랙 레지스트 조액과 네가티브 레지스트 조액의 용해성, 감도, 얻어진 박막의 백화현상을 다음과 같은 방법으로 평가하였다. The solubility of the photoinitiators used in the above Examples and Comparative Examples, the solubility, sensitivity of the black resist crude solution and the negative resist crude solution prepared from them, and the whitening phenomenon of the obtained thin film were evaluated by the following method.

(1) 광개시제의 PGMEA에 대한 용해성(1) Solubility of Photoinitiators in PGMEA

PGMEA 100g에 합성된 옥심에스테르계 광개시제를 소량씩 첨가하여 최대용해량을 측정하였다. 용해도는 용매 100g에 완전히 용해되는 광개시제의 중량을 나타낸다.The maximum dissolved amount was measured by adding small amounts of the synthesized oxime ester photoinitiator to 100 g of PGMEA. Solubility refers to the weight of photoinitiator completely dissolved in 100 g of solvent.

(2) 레지스트 조액의 용해도의 평가(2) Evaluation of solubility of resist crude liquid

상기 조성된 레지스트 감광액 10g에 합성된 옥심 에스테르계 광개시제를 첨가하여 최대 용해량을 측정하였다. 용해량 비율이 큰 값일수록 용해도가 좋은 것을 나타낸다.The maximum dissolution amount was measured by adding the synthesized oxime ester photoinitiator to 10 g of the resist photoresist. The larger the value of the dissolution amount ratio, the better the solubility.

(3) 감도 평가(3) sensitivity evaluation

상기 조성된 각각의 레지스트 감광액을 스핀코터로 유리기판 (삼성코닝사제, Eagle2000)에 도포하고, 핫플레이트로 90도, 1분간 건조했다. 건조 후 촉침식 막두께 측정기 (KLA-Tencor사제, α-step 500)으로 측정하여 얻어진 블랙레지스트 및 투명 네가티브 레지스트의 막두께는 각각 1미크론 및 5미크론이었다. 다음에 이 샘플을 마스크를 통하여 고압수은등으로 노광했다. 이후 농도 0.04% 수산화칼륨 수용액으로 스프레이 현상하여 레지스트 패턴을 얻었다. 40미크론의 마스크 패턴과 같은 치수를 형성할 수 있는 적정 노광량(mJ/sqcm)을 표시하였다. 즉, 노광량이 적은 레지스트는 적은 광에너지로도 화상 형성이 가능하기 때문에 고감도인 것을 나타낸다.Each of the resist photoresist thus prepared was applied to a glass substrate (Samsung Corning, Eagle2000) with a spin coater, and dried at 90 degrees for 1 minute on a hot plate. After drying, the film thicknesses of the black resist and the transparent negative resist obtained by measuring with a tactile film thickness gauge (α-step 500, manufactured by KLA-Tencor) were 1 micron and 5 microns, respectively. This sample was then exposed to a high pressure mercury lamp through a mask. Thereafter, the resultant was spray-developed with 0.04% aqueous potassium hydroxide solution to obtain a resist pattern. Appropriate exposure dose (mJ / sqcm) which can form the same dimension as a 40 micron mask pattern was shown. That is, the resist with a small exposure amount shows high sensitivity since image formation is possible even with a small amount of light energy.

(4) 백화 현상(4) whitening phenomenon

합성된 광개시제를 포함하여 조성된 각각의 레지스트 감광액을 스핀코터로 유기기판에 도포하였다. 이때 광개시제의 용해도에 따라 회전 도포시 결정이 생성되어 도포면이 매우 불량한 경우를 X로, 필름 생성 이후 건조 중 결정이 생성되어 표면이 뿌옇게 흐려지는 경우를 △로 나타내며, 레지스트 조성물에 잘 용해된 상태로 필름 형성시 결정이 생성되지 않고 표면이 깨끗한 경우를 ○로 나타낸다.Each resist photosensitive liquid including the synthesized photoinitiator was applied to the organic substrate with a spin coater. In this case, X is a case in which crystals are formed during rotational coating according to the solubility of the photoinitiator, and the coating surface is very poor, and X is a case in which crystals are formed during drying after film formation, and the surface becomes cloudy, and the film is well dissolved in the resist composition. The case where crystal | crystallization is not produced at the time of formation and a surface is clean is shown by (circle).
