Abstract
Abstract A silver halide color photographic light-sensitive material comprising a support and red-sensitive, green-sensitive and blue-sensitive light-sensitive layers formed on the support. The light-sensitive layers separately contain a coupler of formula (I), a coupler of formula (II) or (III), and a coupler of formula (IV) This novel combination of couplers leads to good color formability, improved color reproducibility, improved image preservability and good color balance.
