AI Technical Summary

Problems solved by technology

In tinting compositions, such reductions in the amount of "active particles" of pigments can be detrimental to the desired tinting effect, while increases in dispersant concentration can negatively affect their performance
In the case of pigment dispersions used to prepare jettable ink compositions, for example, such increased dispersant concentrations can lead to clogging of inkjet print heads, or significantly increase clogging frequency

The resulting diluted dispersion is extracted therefrom. Filter the diluted grind through a suitable screen to separate the beads. Pigment concentration at this stage

The degree is 12% by weight.

[0139] The DIA studied was then added to the pigment dispersant-containing millbase, and water as needed, to obtain

Compositions with a pigment concentration of 10% by weight. Other identical compositions lacking DIA served as reference for each study. with magnetism

The resulting samples were stirred for 5 minutes with a stirrer and their stability was assessed as described below.

[0140] The pigments listed in Table 1 at the end of this specification were used in the examples described herein.

Abstract

Aqueous pigment dispersions containing dispersant improvers, and methods of making and using the same are disclosed.

Description

Improved waterborne pigment dispersions [0001] Cross-application This application claims priority to U.S. Provisional Patent Application Serial No. 62 / 343,111 filed on May 30, 2016 is incorporated by reference for all purposes as if fully set forth herein. technical field [0003] The present disclosure relates to aqueous pigment dispersions, and methods of making and using aqueous pigment dispersions. Background technique [0004] Compositions comprising small particles in a carrier medium are common in many industries. For example, pigments are widely used in In the printing, coatings and paint industries, as well as in some cosmetics. Typically, particles such as pigments are insoluble in the medium that carries them, And thus compositions containing pigments or other particles are generally heterogeneous mixtures in which the particles are dispersed in a carrier. root Depending on the size of the dispersed material, the composition may be referred to as a susp...
