Beschreibung
Zusammenfassung:	The present invention relates to a photosensitive bi-layered resin film, which comprises a first resin film obtained by applying a first composition onto a substrate, followed by curing, and a second resin film obtained by applying a second composition onto the first resin film, followed by curing. The first composition comprises a binder resin, a reactive unsaturated compound, a photopolymerization initiator, a pigment and a solvent, and the second composition comprises an epoxy group-containing acrylic binder resin, a reactive unsaturated compound, a photopolymerization initiator, and a solvent. In addition, the epoxy group is derived from an epoxy group-inducing monomer and the epoxy group-inducing monomer is present in an amount of 5-60 wt% based on the total weight of the monomers forming the epoxy group-containing acrylic binder resin in the second composition. The present invention also relates to a black column spacer obtained by exposing and developing the photosensitive bi-layered resin film, and a color filter comprising the black column spacer. 제1 조성물을 기판 위에 도포하고 경화하여 얻어지는 제1 수지막 및 상기 제1 수지막 위에 제2 조성물을 도포하고 경화하여 얻어지는 제2 수지막으로 이루어져 있고, 상기 제1 조성물은 바인더 수지, 반응성 불포화 화합물, 광중합 개시제, 안료, 및 용매를 포함하고, 상기 제2 조성물은 에폭시기 함유 아크릴계 바인더 수지, 반응성 불포화 화합물, 광중합 개시제, 및 용매를 포함하고, 상기 에폭시기는 에폭시기 유도 단량체로부터 유도되고, 상기 에폭시기 유도 단량체는 상기 제2 조성물 내 에폭시기 함유 아크릴계 바인더 수지를 구성하는 단량체 총량에 대해 5 중량% 내지 60 중량%로 포함되는 감광성 이중층 수지막, 상기 감광성 이중층 수지막을 노광 및 현상하여 제조된 블랙 컬럼 스페이서, 및 상기 블랙 컬럼 스페이서를 포함하는 컬러필터가 제공된다.
