1. A dispersion comprising:
- about 15 wt % to about 50 wt % of at least one organic solvent based on the total weight of the dispersion;
about 50 wt % to about 80 wt % of agglomerates of nanoparticles based on the total weight of the dispersion, wherein the nanoparticles are infrared absorptive, conductive or both infrared absorptive and conductive; and
about 0.5 wt % to about 25 wt % of at least one polycaprolactone-polyamine copolymer based on the total weight of the dispersion,wherein a majority of the agglomerates have an average diameter that is not greater than 100 nanometers, and wherein the dispersion is stable at room temperature for at least one month.

Abstract
A dispersion that includes at least one organic solvent; nanoparticles, wherein the nanoparticles are infrared absorptive, conductive or a both infrared absorptive and conductive; and at least one polycaprolactone-polyamine copolymer, wherein the dispersion comprises agglomerates of the nanoparticles and a majority of the agglomerates have an average diameter that are not greater than 100 nanometers. Compositions, films, articles and light control articles that utilize such dispersions are also discussed.
