摘要

A silver halide color photographic copying material with red-, green- and blue-sensitive layers contains a 2-acylamino-5-phenylsulfonylmethylcarbonylamino-phenol blue-green (i.e. cyan) coupler (I) in the red sensitive layer. A silver halide color photographic copying material with red-, green- and blue-sensitive layers contains a 2-acylamino-5-phenylsulfonylmethylcarbonylamino-phenol blue-green (i.e. cyan) coupler of formula (I) in the red sensitive layer.
