| 摘要 |
The present invention provides an aqueous coating composition for the inner surface of a can, comprising a carboxyl-containing, acrylic-modified epoxy resin (C) prepared by reacting a high-molecular-weight epoxy resin (A) that has a number average molecular weight of 3,000 to 30,000 and is a reaction product of a specific low-molecular-weight cresol novolac epoxy resin (a) and a specific low-molecular-weight cresol novolac phenol resin (b), with a carboxyl-containing acrylic resin (B); the carboxyl-containing, acrylic-modified epoxy resin (C) being neutralized and dispersed in an aqueous medium. The aqueous coating composition of the present invention has good application workability and good film performance, and is free from environmental hormone problems caused by bisphenol A.
