More Information
Summary:NEW MATERIAL:Compounds of formula I wherein A is a group of formula II, IIIor IV; R1 is H, CH3; R2 is a -C2H4- or -CH=CH- crosslinking group. EXAMPLE:A compound of formula V. USE:Vinyl sulfone type monoazoe reactive dyes which dye natural or regenerated cellulosic fibers deep yellow with fastness. PREPARATION:An amine of the formula A-NH3 is diazotized with NaNO2 at 0- 5 deg.C under acidic conditions with hydrochlovic acid and coupled with a coupling component of formula VI at a pH of 0.5-3.5 and at 0-10 deg.C.
