Title:
DISPERSANT OF METAL OXIDE FINE PARTICLE, AND DISPERSOID CONTAINING THE SAME
Document Type and Number:
Japanese Patent JP2022001635
Kind Code:
A
Abstract:
To provide a dispersant for dispersing finely metal oxide fine particles to an organic solvent, and a dispersoid of the metal oxide fine particles excellent in dispersibility.SOLUTION: The above problem is solved by mixing a polyoxypropylene (poly)glycerol ether dibasic acid ester represented by formula (1) as a dispersant of metal oxide fine particles. [Chemical formula 1] (In formula, (PO) represents the propylene oxide, k, l, m are the additional molar number of the propylene oxide and are an integer greater than 0 or larger, where k+l+m=1 to 150, n represents the average degree of polymerization of (poly)glycerol calculated from the hydroxyl group value, and is an integer of 1 to 20, and Ra, Rb and Rc are independently a hydrogen atom or a residue of dicarboxylic acid having 4 carbon atoms, however, not all of them are hydrogen atoms.)SELECTED DRAWING: None
