Page/Page column 8, (2010/10/20)
The present invention provides disazo reactive dyestuffs containing the quaternary group compounds of the general formula (1) wherein R, (W)0?3, (W′)0?3, Y1 and Y2 are defined the same as the specification. The dyes of the invention are distinguished by high fixation and a very good build-up. They are distinguished also by high washing off and a low nylon stain, and they have fiber-reactive properties and are very highly suitable for dyeing and printing of materials containing either cellulose fibers, such as cotton, synthetic cotton, hemp, and synthetic hemp, or amide containing fibres such as wool and nylon.
