| description | To provide a method for producing an epoxy viscous agent for cationic electro-deposition coating, and a cationic electro-deposition coating composition which contains the viscous agent and improves edge corrosion prevention.SOLUTION: A method for producing an epoxy viscous agent for cationic electro-deposition coating includes: (1) an amine modification step of reacting a chain extension epoxy resin, which is obtained by chain extension of a polyphenol polyglycidyl ether type epoxy resin and has a ratio of a relative molecular weight of 100,000 or more by gel permeation chromatography (GPC) of 13.0-18.0 mass%, with an amine compound, and obtaining an amine-modified epoxy resin; (2) a dispersion step of neutralizing a part or all of amino groups of the obtained amine-modified epoxy resin with an acid, and dispersing the neutralized amino groups in a water solvent; and (3) a high molecular weight step of mixing and reacting the obtained dispersion with the polyphenol polyglycidyl ether type epoxy resin, and obtaining an epoxy viscous agent. A cationic electro-deposition coating composition contains the same.SELECTED DRAWING: Figure 1
