| Summary: | 碩士 === 國立臺灣科技大學 === 纖維及高分子工程研究所 === 88 === Abstract
The pyrimidine derivatives were prepared by the reaction of Malonic acid with urea in acetic anhydride. 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.
