Abstract

NEW MATERIAL:An ago dye of formula I (wherein R1 and R2 are H, Cl or Br; R3 is methyl, ethyl or phenyl).
USE: An ago disperse dye capable of dyeing a hydrophobic fiber such as polyester, polyamide or cellulose acetate in a scarlet color with excellent brightness, leveling, light fastness,fastness to sublimation, washing fastness, etc.
PREPARATION: An ago dye of the formula I is prepared by the diazotization of a 2-aminobenzothiazole deriv. of formula II (e.g., 2-amino-6-chlorobenzothiazole) in a mineral or org. acid, followed by the coupling of the rusulting diazo deriv. with a biscyanoethylaminobenzene deriv. of formula III [e.g., N-[3-bis(2- cyanoethyl)-aminophenyl] acetamide].
