    摘要: A one-stage process for the production of a 2-equivalent acylacetamide yellow coupler, in which one hydrogen atom of the .alpha.-methylene group of the acyl acetamide coupler molecule is substituted by a group which is attached through an oxygen or nitrogen atom and which can be split off during chromogenic development with an oxidized color developer containing a primary aromatic amino group, which process is carried out by reactingA 4-equivalent acylacetamide yellow coupler withA compound containing an aromatic hydroxyl group or an --NH-- group in a heterocyclic ringIn the presence of a halogen, or an agent which releases halogen, andA basic condensation agentIn a substantially aprotic solvent.
