Bis-mononicotinotrazine dyes :
Nippon Kayaku introduced a full range of bis-mononicotinotriazine dyes introduced in 1984. An example of this dye type is disazo dye (6). Exhaust dyeing requires a neutrol dyebath at a temperature above the boil. Operating the temperature in the region of 1300C minimizes the diffusion problems expected with such a large molecule. These dyes are suitable for the one-bath dyeing of polyester/cotton blends
