본 연구에서 황색 발색제는 피리딘 존재 하에 α-pivaloyl-2-chloro-5-amino- acetaniline hydrogen chloride와 1-hexadecane sulfonyl chloride를 반응시켜 얻었다. 이 물질은 다양한 분석장비를 이용하여 녹는점, 원소분석기, 적외선분석기, 자외선분석기, 질량분석기로 확인하였다. 황색 발색제를 CD-3(발색현상주약)와 반응시키면 황색이 나타났다.

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.
