    摘要: The use of 4-amino-3-alkoxy-N-ethyl-N- Beta -hydroxyethylaniline developing agents in a diffusion transfer film unit employing at least one nondiffusible coupler capable of reacting with oxidized aromatic primary amino color developing agent to produce a diffusible dye is more effective than analogous paraphenylenediamine color developing agents.
