Light shading resin composition for color filter and color filter

The invention relates to a light shading resin composition for color filter, the characteristic of which is that it contains 80~90 wt% of solvent and solid content; relative to solid content, it contains 8~35 wt% of acrylic acid series photosensitive resin, 45~65 wt% of black pigment, silicon surfactant or fluorin surfactant and initiator for photopolymerization whose HLB value is below 8. The viscosity of the resin composition is between 1.0 and 10.0mPa.s; relative to all solvents, it contains 30~50 wt% of the first solvent having a acetoxyl group in molecule, 0~25 wt% of propylene-glycol diacetate as the second solvent, 30~50 wt% of the third solvent having structure of 3-ethoxy propionic acid in molecule, 10~30 wt% of alicyclic compound having a carbonyl as the fourth solvent. Consequently, it has excellent evenness when coating, dryness of coating substrate and solid components' solubility.
