Abstract

Dyeing properties of a series of 4-amino-4'-fluorosulfonylazobenzene disperse dyes on poly(ethylene terephthalate) (PET) were investigated. Build-up properties and color properties on PET were examined. In particular, the 4-aminoazobenzene dyes containing a nitro group instead of a fluorosulfonyl group at 4'-position were also synthesized in order to compare their dyeing properties on PET with that of 4'-fluorosulfonyl analogues.
