A radiation sensitive composition for color filters comprising (A) a colorant, (B) a binder polymer, (C) a poly-functional monomer, (D) a photopolymerization initiator containing at least one biimidazole compound typified by 2,2'-bis(2-chlorophenyl)-4,4',5,5'-tetrakis(4-ethoxycarbonylphenyl)-biimid azole and 2,2'-bis(2,4-dichlorophenyl)-4,4',5,5'-tetraphenylbiimidazole, and (E) a solvent. The composition can be used for the manufacture of color filters exhibiting excellent photographic sensitivity and superior contrast, while effectively controlling production of residual insoluble material during development process.
