MISTURAS CORANTES. A presente invenção se refere a misturas corantes compreendendo: (A) de 20 a 80% em peso de um ou mais compostos de fórmula (1) em que R~ 1~ é C~ 1~-C~ 12~ alquila, ou C~ 1~-C~ 12~ alquila interrompida por um ou mais átomos de oxigênio ou grupos -COO-, e R~ 2~, R~ 3~, R~ 4~ e R~ 5~, independentemente entre si, são hidrogênio, 01-012 alquila, cloro, bromo, hidróxi ou amino, e (B) de 20 a 80% em peso de pelo menos um corante amarelo disperso adicional, a soma dos componentes (A) + (B) sendo de 100% em peso, e ao uso dessas misturas corantes no tingimento ou impressão de materiais de fibras hidrofóbicas semi-sintéticas ou sintéticas. The present invention relates to dye mixtures comprising (A) from 20 to 80% by weight of one or more compounds of formula (1) wherein R1 is C1-C12alkyl, or C1-C2alkyl interrupted by one or more oxygen atoms or -COO-groups and R2, R3, R4 and R5, each independently of the others, is hydrogen, C1-C12alkyl, chlorine, bromine, hydroxy or amino and (B) from 20 to 80% by weight of at least one further yellow disperse dye the sum of components (A)+(B) being 100% by weight, and to the use of those dye mixtures in the dyeing or printing of semi-synthetic or synthetic hydrophobic fiber materials.
