Abstract
Disclosed is a dye forming coupler represented by formula (I): ##STR1## wherein R.sup.1 and R.sup.2, which may be the same or different, each represents a substituent group, and X is a hydrogen atom or a group which can be eliminated by a coupling reaction with the oxidized species of a primary aromatic amine derivative.
Claims13
A silver halide color photosensitive material comprising a support having thereon at least one layer containing a dye forming coupler represented by formula (I):
- ##STR8## wherein R.sup.1 and R.sup.2, which may be the same or different, each represents a substituent group, and R.sup.1 and R.sup.2 substantially cannot be eliminated when the dye forming coupler is reacted with the oxidized species of a primary aromatic amine derivative, and X is a hydrogen atom or a group which can be eliminated by a coupling reaction with the oxidized species of a primary aromatic amine derivative.
A method for forming color images from a silver halide color photosensitive material comprising a coupling reaction between a dye forming coupler represented by formula (I):
- ##STR9## wherein R.sup.1 and R.sup.2, which may be the same or different, each represents a substituent group, and X is a hydrogen atom or a group which can be eliminated by a coupling reaction with the oxidized species of a primary aromatic amine derivative, and the oxidized species of a primary aromatic amine derivative.
