Disperse dyestuff formulation for dyeing and printing polyester materials in any nuances from yellow to black with high fastness, good levelness and high bath exhaustion contains, in addn. to the usual additives, 2 or more eutectic disperse mix dyestuffs in any ratio, such that 2-3 different combinations give the same huee at 100 deg.C and 130 deg.C. A build-up of hue of the same nuance from yellow to black is obtd. in the critical exhaustion regions from 80 deg.C. to 145 deg.C. by using mixt. (A) as yellow eutectic dyestuff, mixt. (B) as red disperse mix dyestuff, mixt. (C) as blue disperse mix dyestuff. (A) consists of 40-97 (wt.)% 4-anilino-3 -nitro-benzenesulphonanilide (I) and 3-5% bis(N-ethyl-4-(beta,beta-dicyanoethenyl)-3-methyl--phenethyl (II).
