摘要：1-(2',4',6'-Trichlorophenyl)-3-atnino-5-pyrazolone (3) was synthesized by the condensation of 2,4,6-trichlorophenyl-hydrazine with ethyl beta-ethoxy-beta-imino-propinate in the presence of sodium ethoxide. Three monomers of the couplers were obtained by the reaction of 3 or its 4-position derivatives with methacryloyl chloride. Three latex magenta couplers were formed by emulsion copolymerization of these monomers and butyl acrylate. The reaction intermediates and the monomers were characterized by IR and H-1 NMR spectra. Some factors of affecting the reactions mentioned above were discussed.
