참여 물질

반응 단계

Into the mixture comprising 0.78 g of Comparative Coupler (C-2), 0.80 g of N-ethyl-N-(β-methanesulfonamidoethyl)-3-methyl-4-aminoaniline sulfate, 3.75 g of sodium carbonate, 60 ml of chloroform and 50 ml of water, a solution of 10 ml of water having dissolved therein 1.65 g of ammonium persulfate was gradually added with stirring at room temperature. After stirring the reaction solution for one hour, a chloroform layer was separated and the reaction solution was subjected to purification through silica gel column chromatography to obtain Azomethine Dye (CD-2). Further, Azomethine Dyes (D-1) to (D-4) were synthesized using the couplers of the present invention in place of Coupler (C-2). ##STR5##
