Abstract
Provided is a nanodiamond dispersion composition having excellent dispersibility of nanodiamond particles in an organic dispersion medium even when the organic dispersion medium has a small SP value. The nanodiamond dispersion composition according to an embodiment of the present invention includes an organic dispersion medium, nanodiamond particles dispersed in the organic dispersion medium, and a fatty acid ester dispersing agent. The fatty acid ester dispersing agent preferably has a mass loss rate of 20% or less when held in an air atmosphere at a temperature of 200° C. for 180 minutes. The fatty acid ester dispersing agent preferably has an acid value of 40 mgKOH/g or less.
Claims19
