| titleOfInvention | Polyester material dyed with yellow methine dyes |
| abstract | Yellow methine dyes are produced according to the following synthesis: A N-2-hydroxyethylaniline is treated with an aroyl chloride, whereby there is produced an aroyl ester, which is converted to an aldehyde via the Vilsmeier synthesis; this intermediate aldehyde is converted into the yellow methine dyes of the invention by treatment with a nitrile reactant. The resultant yellow methine dyes are excellent dyestuffs for polyester fabrics, in particular polyethylene terephthalate. The properties of these dyeings are very satisfactory; in particular, the fastness to light and resistance to sublimation when subject to heat treatment are excellent. The dyes are applied by carrier dyeing, pressure dyeing and by thermofixation, as well as other established methods. |
