본 발명의 바인더 수지로는 산가가 20 내지 200(KOH ㎎/g)의 범위가 바람직하다. 산가가 상기 범위에 있으면,현상액 중의 용해성이 향상되어, 비-노출부가 쉽게 용해되고 감도가 증가하여, 결과적으로 노출부의 패턴이 현상시에 남아서 잔막율(film remaining ratio)을 개선하게 되어 바람직하다. 여기서 산가란, 아크릴계 중합체 1g을 중화하는 데 필요한 수산화칼륨의 양(mg)으로서 측정되는 값이며, 통상적으로 수산화칼륨 수용액을 사용하여 적정함으로써 구할 수 있다. 또한, 겔 투과 크로마토그래피(GPC; 테트라히드로퓨란을 용출용제로 함)로 측정한 폴리스티렌 환산 중량평균분자량(이하, 간단히 '중량평균분자량'이라고 한다)인 3,000 내지 200,000, 바람직하게는 5,000 내지 100,000인 바인더 수지가 바람직하다. 분자량이 상기 범위에 있으면, 코팅 필름의 경도가 향상되어, 잔막율이 높고, 현상액 중의 비-노출부의 용해성이 탁월하고 해상도가 향상되는 경향이 있어 바람직하다. The acid value of the binder resin of the present invention is preferably in the range of 20 to 200 (KOH mg / g). When the acid value is in the above range, the solubility in the developer is improved, the non-exposed portion is easily dissolved and the sensitivity is increased, and as a result, the pattern of the exposed portion remains during development, thereby improving the film remaining ratio. Here, the acid value is a value measured as the amount (mg) of potassium hydroxide necessary for neutralizing 1 g of the acrylic polymer, and can be generally determined by titration using an aqueous solution of potassium hydroxide. The weight average molecular weight (hereinafter, simply referred to as "weight average molecular weight") of the polymer of 3,000 to 200,000, preferably 5,000 to 100,000 in terms of polystyrene measured by gel permeation chromatography (GPC; tetrahydrofuran as an elution solvent) A binder resin is preferable. When the molecular weight is within the above range, the hardness of the coating film is improved, the residual film ratio is high, the solubility of the non-exposed portion in the developer is excellent, and the resolution tends to be improved.
바인더 수지의 분자량 분포 [중량평균분자량(Mw)/ 수평균 분자량(Mn)]는 현상성 측면에서 1.5 내지 6.0인 것이 바람직하고, 1.8 내지 4.0인 것이 보다 바람직하다.

The content of the binder resin is not particularly limited and may be specifically 1 to 35 parts by weight, preferably 5 to 30 parts by weight based on 100 parts by weight of the total of the colored photosensitive resin composition. If the content of the binder resin is in the range of 1 to 35 parts by weight, the solubility in the developing solution is sufficient, so that development residue does not easily occur on the substrate of the non-pixel portion, and the film portion of the pixel portion of the exposed portion is hardly reduced. It is preferable since the property tends to be good.

(1) 현상속도 평가(1) Development speed evaluation
현상시 비노광부가 현상액에 완전히 용해되는데 걸리는 시간을 측정하였다. The time taken for the unexposed area to completely dissolve in the developing solution at the time of development was measured.
(2) 감도 평가(2) Sensitivity evaluation
현상 후 패턴의 뜯김이 없는 박막을 형성하기 위해 필요한 최저 노광량을 측정하였다.The minimum amount of exposure required to form a thin film without peeling of the pattern after development was measured.
(3) 현상 (3) the phenomenon 잔사Residue 평가 evaluation
착색 감광성 수지 조성물을 유리기판에 스핀 코팅하여 약 100 ℃로 100 초 동안 전 열 처리하고, 두께가 약 2.2 ㎛인 균등한 필름으로 형성하였다.The colored photosensitive resin composition was spin-coated on a glass substrate and heat-treated at about 100 캜 for 100 seconds to form an equivalent film having a thickness of about 2.2 탆.
그 후, 마스크로 40mJ/cm2 노광 후 25 ℃에서 0.04 % KOH용액으로 60초간 현상을 진행하면서 현상시간을 확인하고 육안관찰하여 기판상 현상 잔사가 없는 경우는 '○'로, 기판상 현상 잔사가 나타난 경우는 '×'로 나타내었다.Then, if by checking the processing time and proceed with the developer for 60 seconds in 0.04% KOH solution at 25 ℃ after second exposure 40mJ / cm as a mask, and visually observed without the substrate the development residue is '○' in the substrate the development residue Is shown as 'x'.
(4) 패턴 직진성 평가(4) Pattern straightness evaluation
생성된 패턴을 광학현미경을 통하여 평가하였을 때, 패턴상에 요철, 굴곡이 발생하는 정도를 판단하여 아래와 같이 나타내었다.When the generated pattern was evaluated by an optical microscope, the degree of occurrence of concavity and convexity on the pattern was judged as follows.
<평가 기준><Evaluation Criteria>
○ : 패턴상 오류없음○: No error in pattern
△ : 패턴상 오류 1 내지 3개C: Errors in pattern 1 to 3
× : 패턴상 오류 4개 이상×: 4 or more errors in the pattern
(5) (5) 착색력Coloring power 평가 evaluation
착색력은 동일한 색도 및 막두께일 때의 착색 감광성 수지 조성물 내에 포함된 착색제인 안료의 중량비율(PWC)로 나타내었다. 이 때 착색력 평가 기준은 하기와 같다.The tinting strength was expressed by the weight ratio (PWC) of the pigment as a colorant contained in the colored photosensitive resin composition at the same chromaticity and film thickness. The evaluation criteria for the tinting strength are as follows.
<평가기준><Evaluation Criteria>
○: PWC<0.35?: PWC <0.35
△: 0.35≤PWC<0.45?: 0.35? PwC <0.45
×: PWC≥0.45×: PWC ≥ 0.45
상기 표 2를 참조하면, 본 발명의 범위에 속하는 실시예들은 비교예들에 비해 착색력, 현상속도 및 감도가 우수하고 현상 잔사가 발생하지 않으며 패턴 직진성이 개선된 것을 확인할 수 있었다.
Referring to Table 2, it can be seen that the Examples according to the present invention have excellent tinctorial strength, development speed and sensitivity, no development residue, and improved pattern straightness as compared with Comparative Examples.
