The pyrimidines reached with sodium nitrite to produced the Nitroso pyrimidines. The Aza-methine dyes were synthesised from the reaction of nitroso pyrimidinetrione with 1,3,3-trimethyl-2-methyene-indoline derivatives and the some pyridone derivatives , respectively. The structure of the dyes were confirmed by E.A、IR、MS 、1H-NMR and spectral analysis. The solvent effect in CHCl3 and DMSO were studied. The pyrimidine dyes were applied to dyeing on polyester fabrics . The colour properties were evaluated with CIE system.The sublimation fastness of dyes on Polyester fabrics were shown in the range among 4~5grades. The lightfastness of dyes on Polyester fabrics were shown in the range among 3~4grades.
