An anti-settling agent composition for aqueous coating materials, comprising [A] a polyamide which is obtained by polymerizing a diamine having 2-12 carbon atoms and an excess amount, relative to diamine, of either a dicarboxylic acid having 4-36 carbon atoms or a mixture of a dicarboxylic acid having 4-36 carbon atoms and a monocarboxylic acid having 2-22 carbon atoms, and [B] a hydrophobic organic compound which is a hydrocarbon modified with 1-3 hydroxyl groups and/or carboxyl groups and having 10-54 carbon atoms, and which has a freezing point of 20° C. or less or does not have a definite freezing point. The anti-settling agent is able to be easily dispersed in a coating material even if directly added into the coating material without being diluted when added into the coating material, and which imparts the coating material with excellent anti-settling properties.
