Abstract
Abstract Novel yellow 2:1 chrome complexed dye developer particularly useful in photographic products and processes are presented by this invention. The novel 2:1 chrome complexed dye developers have the following structure: ##STR1## where each A is a phenyl radical; each B is a phenyl or nitrogen containing heterocylic radical; Y is a silver halide developing substituent; each n is 0 or 1 but at least one n must be 1; R is N or CH; R 1 is ##STR2## if R is N but R 1 is --O--if R is CH and X is a cation.
