In this paper, magenta coupler was prepared by the reaction of 1-(2,4,6-Trichlorophenyl)-3-(5-amino-2-chloroanilino)-5-pyrazolone with 2,4-di-tert-pentyl-phenoxy butanoyl chloride in the presence of pyridine. The product was identified by using various analytical tools such as melting point, elemental analyzer, IR spectrophotometer, UV-Vis spectrophotometer and GC-mass spectrometer. The reaction of magenta coupler with CD-3 (color development agent) was shown magenta color.
