This disclosure relates to a photosensitive resin composition, a photosensitive resin layer using the same, a color filter, and a CMOS image sensor. An embodiment provides a red photosensitive resin composition including (A) a colorant; (B) a binder resin; (C) a photopolymerizable compound; (D) a photopolymerization initiator; and (E) a solvent, wherein the colorant includes a pigment dispersion and the pigment dispersion includes 50 wt% to 80 wt% of C.I. red pigment 254, 20 wt% to 40 wt% of C.I. yellow pigment 139, and 0.1 wt% to 10 wt% of C.I. green pigment 58 based on 100 wt% of a total pigment. This disclosure may implement image quality by the image sensor at a certain level.
