<p>A dispersant for fine particles, containing at least one member selected from the group consisting of esters (I) and (II) of erythritol and/or erythritol condensate with fatty acids, polycondensates of erythritol and/or erythritol condensate with polycarboxylic acids, polycondensates of erythritol and/or erythritol condensate with the esters and polycarboxylic acids, polycondensates of esters of erythritol and/or erythritol condensate with polycarboxylic acids with fatty acids, and polycondensates of erythritol and/or erythritol condensate with fatty acids and/or polycarboxylic acids: (I) (II) [wherein R1 to R4 are each independently hydrogen, a fatty acid residue, or a polycarboxylic acid residue; and R5 and R6 are each independently hydrogen, a fatty acid residue, or a polycarboxylic acid residue]. The dispersant is excellent in the ability to disperse fine particles and is little deteriorated in the properties (including odor and color) in thermal stability test.</p> |
