ABSTRACT:
The present invention relates to new .alpha.-hydrazono .alpha.-phenyl acetonitriles, which can be used in particular as disperse dye-stuffs for the coloration of artificial or synthetic materials. They may be represented by the general formula: ##STR1## in which R.sub.1 represents a hydrogen or halogen atom or a nitro, trifluoromethyl, alkyl or alkoxy group, R.sub.2 represents a hydrogen or halogen atom or a cyano group, and the benzene nucleus A carries 1 to 3 identical or different substituents selected from halogen atoms and the trifluoromethyl, alkyl, alkoxy and --NR.sub.3 R.sub.4 groups, R.sub.3 representing a possibly substituted alkyl group and R.sub.4 representing a hydrogen atom or a possibly substituted alkyl group. These compounds provide colorations which are very fast to light on polyester fibers.
