摘要： A photographic yellow dye-forming coupler having the general formula:
wherein R¹ is an alkyl group of 1-4 carbon atoms, ball is a ballast group of such size and configuration as to render the coupier non-diffusible in photographic layers,
Y is CO, PO₃ or SO₂,
X is an aryloxy coupling-off group, and
n is 1 or, when Y is PO₃, n is 2.摘要翻译： 具有通式的照相黄色成色剂：
