Liquid dispersed dye of the azo or anthraquinone type
A liquid dispersed dye of the azo or anthraquinone type that includes a dispersing agent and dispersing assistant in order to keep the dye dissolved in liquid without sedimentation. The preferred dispersing agent is a sulfonated lignin salt and the preferred dispersing assistant is a surfactant such as polyethylene glycol epoxide ether (EO-1), polyethylene glycol phenolic-formaldehyde epoxide ether (EO-2), or polyethylene glycol amino methyl... moreLiquid dispersed dye of the azo or anthraquinone type
A liquid dispersed dye of the azo or anthraquinone type that includes a dispersing agent and dispersing assistant in order to keep the dye dissolved in liquid without sedimentation. The preferred dispersing agent is a sulfonated lignin salt and the preferred dispersing assistant is a surfactant such as polyethylene glycol epoxide ether (EO-1), polyethylene glycol phenolic-formaldehyde epoxide ether (EO-2), or polyethylene glycol amino methylene epoxide ether (EO-3).
This invention concerns liquid dispersed dyes of the azo and anthraquinone types, particularly non-soluble dyes mixed with a dispersing agent and a dispersing assistant in order to allow the non-soluble dye to dissolve or evenly disperse in the liquid, thus providing the dye with excellent thermal and storing stability. The liquid dispersed dye of the azo or anthraquinone type is capable of holding of a homogenous liquid phase to prevention of sedimentation.
