摘要： The present disclosure is concerned with enhancing the solubility of dispersed anionic dyes upon the dilution of their dispersions with room temperature water. Concentrated dispersions of such dyes with acceptable stability and low shear viscosities are disclosed which are more readily diluted to dissolve the dispersed dyestuff because they contain certain chelating agents are described. These agents have at least one free or appropriately neutralized acid group, with carboxylic acid groups being preferred. The appropriae cations include ammonium or lithium ions. The free acid groups are subsequently neutralized with these appropriae cations so that the final dispersions are preferably about neutral, i.e have pH values about 7. A further improvement to the dilutability by the addition of a surfactant, preferably a non-ionic surfactant, is also discssed. The preferred dispersions dilute to a solution free of particles visible to the unaided human eye within three minutes of being combined at a rate of three grams of dispersion per liter of room temperature water.

摘要： The present disclosure is concerned with new modifications of the dyestuff Color Index Acid Blue 324 which have significant advantages over the known form of this dyestuff. In particular, the preferred modification is much easier to isolate from an aqueous medium by filtration and the isolated product has a higher purity. The filtration proceeds much more rapidly and gives a filter residue of a much higher solids content. Furthermore, this new form of the dyestuff imparts a dramatically lower viscosity to aqueous dispersions or slurries prepared from it than are obtained using the old form of this dyestuff. These modifications are obtained by heating an aqueous dispersion or slurry of the known form of Color Index Acid Blue 324 to temperatures in excess of about 97.degree. C. and for the preferred form in the presence of a substance which reduces the surface tension between the dispersed organic dyestuff phase and the aqueous dispersing medium. The obtained dyestuff modifications display Debye-Scherrer X-ray diffraction patterns substantially different from that of the commercially available Color Index Acid Blue 324 evidencing that new crystal forms have been obtained. This is confirmed by optical microscopy which shows that the dyestuff undergoes a transformation from sharp, thin needles to either parallelograms or hexagons.

摘要： The present disclosure is concerned with aqueous dispersions of anionic acid dyes, especially the monosulphonated level dyeing acid dyes, which have low room temperature, low shear viscosities and good storage stability. This low viscosity enables them to be readily poured, pumped and otherwise handled. These dispersions comprise dyestuff solids with a controlled particle size distribution having a median value between about 1 and 10 microns; an anionic dispersant; and an electrolyte. In a preferred embodiment the pH is adjusted to give an optimum viscosity value. Another preferred feature is the adjustment of the rheology with a thickening agent such as xanthan gum. These dispersions find particular utility in the continuous dyeing of carpet, especially in Kuesters or foam dyeing equipment.
