ABSTRACT:
Methine dyes from tetrahydroquinoline compounds containing N-thioether substituents, in general produce bright yellow shades when applied to polyester fabrics by conventional dyeing procedures, have improved properties such as dyeability, fastness to light, resistance to sublimation, insensitivity to pH changes, and dye at the boil and under pressure to the same depth of shade. These compounds are particularly useful in the thermal fixation technique for dyeing polyester materials.
