摘要

According to the present invention, an acrylic copolymer resin containing a carboxylic acid group is prepared; Reacting the epoxy resin with a phenol-based compound to prepare a phenol-modified epoxy resin; Ester-reacting the acrylic copolymer resin and the phenol-modified epoxy resin to prepare an acrylic-modified phenol-modified epoxy resin; A method for producing a water-soluble acrylic-modified phenol-modified epoxy resin, comprising preparing a water-soluble acrylic-modified phenol-modified epoxy resin by neutralizing it, the water-soluble acrylic-modified phenol-modified epoxy resin prepared thereby, An aqueous coating composition comprising is provided. The water-soluble acrylic-modified phenolic-modified epoxy resin according to the present invention and the aqueous coating composition containing the same have excellent physical properties, and can be applied to most of the conventional uses in which an epoxy resin is used, and the formed coating film is post-molded. It is excellent in processability, chemical stability in contents, and thermal stability at high temperature, and thus can be usefully applied as an aqueous coating composition for inner and outer surfaces of a two-piece can lid and EOE.
