Abstract
1529462 1-Trichlorophenyl-3-anilino-5 pyrazolones KONISHIROKU PHOTO INDUSTRY CO Ltd 13 Oct 1975 [14 Oct 1974] 41769/75 Heading C2C [Also in Divisions G2 and G3] A magenta-forming coupler of the formula is prepared by refluxing 1-(2,4,6-trichlorophenyl) - 3 - (2 - chloro - 5 - aminoanilino) - 5 - pyrazolone, 4-lauramidophenylsulphonyl chloride and acetonitrile. A magenta-forming coupler of the formula is prepared similarly.
