Abstract
NEW MATERIAL:The monoazo dye of formula I [X is (tetrahydro)furfuryl, benzyl, or β-phenylethyl; Y and Z are H, Cl or Br; R is lower alkyl].
EXAMPLE: The compound of formula II.
USE: For dyeing of hydrophobic fibrous material such as polyamide, acetate, polyester, etc. (esp. polyethylene terephthalate fiber) in yellow color. It has high suitability for discharge printing as well as high color fastness.
PROCESS: The compound of formula III (e.g. p-carbotetrahydrofurfuryloxyaniline) is converted to an aqueous solution of a diazonium salt by the treatment with sodium nitrite in a mineral acid such as hydrochloric acid, sulfuric acid, etc., and then coupled with the compound of formula IV (e.g. 1-phenyl-3-carboethoxypyrazolone) to obtain the objective compound.
