Disperse mon:azo dyes derived from di:halo-nitroaniline - used for dyeing and printing aromatic polyester, polyamide, cellulose acetate in reddish-blue shades

摘要

The dyestuffs are of formula (I) (where R' and R2 are independently alkyl; Y and Z are independently halogen; X is H, hydro-carbon, amino, -NHW or -OW, W being hydrocarbon gp.). Used for dyeing and printing synthetic textiles, partic. aromatic polyesters but also sec. cellulose acetate, cellulose triacetate and polyamides bluish-red shades fast to dry heat-fixing and sublimation. The textiles may also be transfer-printed, and polymers such as aromatic polyesters, may be bulk dyed.
