Dispersants consisting of sulfonate anion and ammonium cation for aqueous fluorescent dye or aqueous dispersion composition of fluorescent dye comprising the same

摘要

The present invention relates to a dispersant for an aqueous fluorescent dye comprising a sulfonate anion and an ammonium cation or a fluorescent dye aqueous dispersion composition containing the same, wherein the dispersant has a structure similar to a fluorescent dye. Accordingly, the present invention can provide an environmentally friendly fluorescent dye that can easily dye polyester fibers even when a small amount of a surfactant is added by increasing the water dispersibility of the fluorescent substance in the dye through use of the dispersant, Structure of the present invention can increase the coloring power of the fluorescent dye and solve the disadvantage of the dye composition which has lowered the coloring power due to the use of various additives.
