VISCOSITY REDUCING AGENT FOR COMPOSITE DISPERSANT
PROBLEM TO BE SOLVED: To provide a viscosity reducing agent for composite dispersant, which can reduce thickening when a naphthalene-based dispersant and a polycarboxylic acid-based dispersant are used in combination.SOLUTION: Provided is a viscosity reducing agent for composite dispersant, used for composite dispersant comprising (A) a naphthalene-based dispersant and (B) a carboxylic acid-based dispersant or a phosphoric acid-based dispersant, comprising at least one or more compounds (except naphthalene-based dispersants, carboxylic acid-based dispersants, and phosphoric acid-based dispersants) which satisfy at least one of the following conditions 1 to 3 and at least one of the following conditions 4 and 5. Condition 1: has a hydrocarbon group (except aromatic hydrocarbon groups) having 10 or more carbon atoms. Condition 2: has an aromatic ring. Condition 3: has at least one of a propyleneoxy group and a butyleneoxy group. Condition 4: has an ethyleneoxy group. Condition 5: has a sulfuric ester group.SELECTED DRAWING: None
