초록
Twelve Laminoazobenzene disperse dyes were synthesized usin two diazo component(Lnitroaniline, 2,Ldinit- roaniline) and six coupling components(milnt N-melhylaniline, N-ethylaniline, Nutimethylaniline, Nu4iethylaniline, Nu- ptihydroxyethylaniline). The effect of the nature of the substituents of Laminoazobenzene disperse dyes on dyeing property and color fastness(light ftsoess, sublimation flsoess and wash flsoess) on polyester, nylon 6, cellulose acetate fibers were investigated. The relations between light fulness and mechanism of fadins by light, sublimation and dye structure, and wash fastness and affinity were also described.
