초록

알칼리 가용성, 광경화형 폴리에스터를 합성하기 위해 플루오렌형 에폭시 아크릴레이트에 다양한 산 2 무수물을 반응시켰다. LCD(liquid crystal display) 컬러 필터용 블랙매트릭스를 제조하기 위해서 합성된 폴리에스터와 카본블랙 등을 혼합하여 포토레지스트 용액을 조제한 후 리소그래피 공정을 통해 유리 기판 위에 블랙매트릭스 패턴을 형성하였다. 합성된 다양한 폴리에스터의 특성과 리소그래피 패턴을 비교 조사하였다.

Alkali soluble and photo-curable polyesters were prepared from fluorene epoxy acrylate and various aromatic dianhydrides. To make a black matrix for LCD color-filter application, photo-resist solution was made by mixing synthesized polyester as binder, carbon black as pigment, initiator and multifunctional monomer in solvent. Black matrix pattern was formed on the glass substrate by lithography process. In this study, we synthesized various polyester-based binder polymers for LCD color-filter applications, and compared the analytical properties of those polymers and lithography patterns.

Keywords:epoxy acrylate;alkali soluble and photosensitive polyester;LCD color-filter;black matrix
