Abstract: A nano-emulsion composition having a small particle size and ultra-low concentration and a preparation method thereof is disclosed. The raw materials of the composition comprise, in terms of percentage by weight, 0.002% to 0.2% of a polymer-containing homogeneous microemulsion, water, and 99.998% to 99.8% of an organic salt solution or inorganic salt solution. The composition is prepared by diluting a polymer-containing homogeneous microemulsion with water or a salt solution. The polymer-containing homogeneous microemulsion is formed by mixing the following raw materials, in terms of percentage by weight: 8% to 40% of a surfactant, 0.5% to 10% of a polymer, 10% to 30% of an alcohol, 3% to 30% of an oil, 0% to 20% of a salt, and balance of water. The composition of the invention is low in concentration, low in cost, narrow in particle size distribution, good in stability, simple in preparation, and convenient for storage and use.

Abstract: An aqueous dispersion contains pigment colorant particles (of various types of materials) at 5 weight % and up to and including 80 weight %; a dispersing polymer that is prepared from the Diels Alder adduct of 3-maleimidopropionic acid and furfuryl (meth)acrylate; and an aqueous medium. The weight ratio of the pigment colorant particles to the dispersing polymer is from 19:1 to and including 2:1. This aqueous dispersion can be incorporated into an aqueous inkjet ink composition that can be used in various inkjet printing methods to provide opaque images particularly when titanium dioxide particles are used as the pigment colorant.
