Abstract
A fine particle dispersant containing at least one member selected from the group consisting of ester compounds of the following general formula (I) of ditrimethylolpropane and a fatty acid(s), polycondensates of ditrimethylolpropane and a polyvalent carboxylic acid(s), polycondensates of the ester compound of the following general formula (I) and the polyvalent carboxylic acid(s), polycondensates of an ester compound of ditrimethylolpropane and the polyvalent carboxylic acid(s) and the fatty acid(s), and polycondensates of ditrimethylolpropane, the fatty acid(s) and the polyvalent carboxylic acid(s). wherein Rto Reach independently represent a hydrogen atom or a fatty acid residue, with the proviso that at least one of them is a hydrogen atom. This fine particle dispersant is excellent in fine particle dispersibility and the properties (smell and color) thereof are scarcely deteriorated in heat stability tests.
