A red pigment dispersion for a color filter and a red photosensitivity for a color filter, in which aggregation and crystal precipitation of the pigment are suppressed even after the high-temperature heating step in the color filter step, and particularly high brightness and high contrast can be achieved. A functional resin composition is provided. (A) a red pigment having a diphenyl diketopyrrolopyrrole skeleton, (B) an asymmetric diketopyrrolopyrrole derivative, (C) C.I. I. A block comprising a sulfonated derivative of one or more yellow pigments selected from the group consisting of CI Pigment Yellow 138, 139, 150, 215, and derivative pigments thereof; and (D) a salt of a tertiary amine or a quaternary ammonium salt A red pigment dispersion for color filters and a red photosensitive resin composition for color filters containing the pigment dispersion, which is a copolymer, and (E) a solvent.
