Abstract
NEW MATERIAL:Water-insoluble monoazo dye of formula I (D is aromatic or heterocyclic X is F, lower alkoxy; R1 is H, lower alkyl, lower alkoxy; R2,3 are H. lower alkyl, aralkyl, aryl; provided that both of the R2 and R3 are not H at the same time).
EXAMPLE: Blue dye of formula II.
USE: Dye for polyamide, polyesfter, and cellulosic ester fibers.
PROCESS: Diazotized amines D-NH2 are coupled with a coupling component corresponding to the compound I, in a weak acidic aqueous medium at a low temperature.
