Reaction Steps

A mixture of 4 g of chrysoidine and 20 g of chlorosulfonic acid was stirred at a temperature lower than 20° C. for 2 hours and poured in ice water to salt out chrysoidine sulfochloride. Then 5 g of chrysoidine sulfochloride were reacted with 20 g of stearyl amine molten at 70° C. The reaction product was extracted with benzene and benzene was evaporated yield the intended chrysoidine-N-stearylsulfonamide. A liquid developer was prepared by dispersing 0.1 g of the resulting product in 1 liter of Shellsol 71 (product of Shell Petroleum Co.), which is an isoparaffin hydrocarbon, by effecting ultrasonic vibration for 2 minutes. This liquid developer was excellent in dispersibility and gave a yellow visible negative image of good fixing property.
