Dye D6 of formula III wherein R1 =n--C4H9, R2 =n--C3H7, n=2, and X=Ni(CN)4-2, was prepared by Method IA, using 5.0 g of the dye perchlorate dissolved in 300 ml of methanol and 50 ml water to which was added with boiling a solution of 12 g of potassium tetracyanonickelate in 50 ml water, which after boiling for 10 minutes, cooling and addition of 200 ml water, yielded 4.8 g of the dye tetracyanonickelate upon filtration. The presence of the dye cation component was confirmed by the visible absorption band characteristics of the dye (λmax, half-bandwidth and band shape), which were identical to those of the parent perchlorate dye. (λmax =672 nm; εmax =206,300 1 mol-1 cm-1 in dichloromethane).
