Claim 4
Dependent Claim
88 words
A process for dyeing polyester fibers, in which polyester fibers are dyed by using a mono-azo dye represented by the following general formula: ##STR126## wherein R 1 and R 2 individually represent hydrogen atom, substituted or non-substituted alkyl group, alkenyl group, and cyclohexyl group, R 3 represents hydrogen atom, chlorine atom, bromine atom, alkyl group, substituted or non-substituted alkoxy group or alkenyl group, and R 4 represents hydrogen atom, chlorine atom, bromine atom, alkyl group, alkoxy group, hydroxy group, acylamino group, alkoxycarbonylamino group, aralkyloxycarbonylamino group or alkylaminocarbonylamino group.
Claim 5
Dependent Claim
67 words
