| abstract | Monoazo compounds of the formula <IMAGE> wherein R1 is chloro, bromo nitro, C1-4alkylsulfonyl, phenylsulfonyl, (C1-4alkyl)carbonyl or benzoyl, each of R2 and R3, independently, is hydrogen, chloro or bromo, with the proviso that at least one of R2 and R3 is hydrogen, each of R4 and R5, independently, is C1-4alkyl, <IMAGE> +TR <IMAGE> or in which each of R10, R11 and R12, independently, is hydrogen, chloro, bromo, methyl, methoxy or ethoxy, and R6 is C1-4alkyl, (C1-4alkoxy)C2-4alkyl, phenyl or phenyl substituted by up to three substituents selected from the group consisting of choro, bromo, methyl, methoxy and ethoxy, which compounds are useful as disperse dyes for substrates consisting of or comprising hydrophobic, high molecular weight synthetic or semi-synthetic organic fibers such as polyesters, synthetic polyamides and cellulose 21/2 acetate and triacetate. The dyeings exhibit notable fastness to light, thermofixation, sublimation, pleating, wet treatments, perspiration, solvents, lubricants, rubbing, cross dyeing, ozone, gas fumes and chlorine and stability to reduction when dyed with wool. The dyes build-up particularly well on polyesters. |
