[0164] (Preparation of photosensitive resin composition for light-shielding layer)

[0165] A photosensitive resin composition for a light blocking layer was prepared using the following components.

[0166] (A) colorant

[0167] (A-1) Blue material

[0168] (A-1-1) A dye represented by the following Chemical Formula 4 (cyan-1, KISCO) was used.

[0169] [chemical formula 4]

[0170]

[0171] (A-1-2) A mill base (mill base) containing pigment V23 manufactured by BASF Corporation (Sakata Co., Ltd.) was used.

[0172] (A-1-3) A color paste (Sakata Co., Ltd.) containing Pigment B15:6 represented by the following Chemical Formula 18 and manufactured by BASF Corporation was used.

[0173] [chemical formula 18]

[0174]

[0175] (A-2) Red material

[0176] Orange 63 (Sakata Co., Ltd.) was used.

[0177] (B) Binder resin

[0178] As the cardo-based binder resin, V259ME produced by NSCC was used.

[0179] (C) Photopolymerizable monomer

[0180] Dipentaerythrito...

Embodiment 1 and 2 and comparative example 1

[0188]A photosensitive resin composition for a light blocking layer was prepared by mixing components according to the compositions provided in Table 1 below. Specifically, a photopolymerization initiator was dissolved in a solvent, and the solution was stirred for 30 minutes. Then, a binder resin and a photopolymerizable monomer are sequentially added thereto. The mixture was stirred for 1 hour. Then, the additives are added to the stirred mixture, and finally the colorant is added thereto. Stir the resulting mixture for more than or equal to 2 hours to prepare a photosensitive resin composition for a light-shielding layer.

The photosensitive resin composition for the light blocking layer includes (A) a colorant including a blue material including a dye represented by the following Chemical Formula 1, and a red material, (B) a binder resin, (C) a photopolymerizable monomer, (D) a photopolymerization initiator, and (E) a solvent, and a light blocking layer using the same. In Chemical Formula 1, each substituent is the same as defined in the detailed description.

Description

[0001] related application [0002] This application claims priority and benefit from Korean Patent Application No. 10-2012-0153565 filed in the Korean Intellectual Property Office on December 26, 2012, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to a photosensitive resin composition for a light-blocking layer and a light-blocking layer using the photosensitive resin composition. Background technique [0004] The photosensitive resin composition used for the light-shielding layer is an essential material for preparing display devices such as the light-shielding layer, liquid crystal display materials, organic light-emitting elements (EL), and display panel materials. A light-blocking layer for a color liquid crystal display or the like is formed using the photosensitive resin composition for a light-blocking layer. The light blocking layer is formed between colored layers such as red, green, blue...
