Versuchsvorschrift

To a mixture of 0.73 g of the following coupler for comparison (C-2) (Compound (2) described in U.S. Pat. No. 5,455,149), 0.80 g of N-ethyl-N-(β-methanesulfonamidoethyl)-3-methyl-4-aminoaniline sulfate, 3.75 g of sodium carbonate, 60 ml of THF and 50 ml of water, a solution of 1.45 g of ammonium persulfate dissolved in 10 ml of water was gradually added with stirring at room temperature. After stirring the reaction mixture at 60° C. for 10 minutes, the THF layer was separated and purified by silica gel column chromatography, to obtain a dye for comparison (CD-2) which was a yellow azomethine dye for comparison as shown below.
