Synthesis of some New Disperse Dyes for Dyeing Polyester Fibre.(Dept.T)

Reaction of 2-phenyl--4- (2-quinolyl) -2--oxazolin-5-one 1 with diamines in different conditions gave compounds 2,3,4,5,7 and 9, respectively. Diazotisation and coupling of compound 4 gave compound 6. All these compounds were used as dyes whose gives a high substantivety and high flourescence colours to polyester fibres, compared with polyamide and triacetate fibres. The dyed polyester samples give a good fastnesses to washing, rubbing and light.
