Abstract
An aqueous coating composition comprising an acrylic resin-modified epoxy resin (D), which is obtained by the reaction between a mixture of a bisphenol F based epoxy resin (A) and a bisphenol F based phenoxy resin (B) and an acrylic resin having carboxyl functionality (C), said acrylic resin-modified epoxy resin (D) being dispersed into water, preferably by using ammonia or amine, provides a composition with low viscosity, excellent storage stability and excellent application workability. In addition, the coating of the present invention can be applied to an interior surface and the resulting film has a smooth surface, excellent processability, excellent retorting resistant properties, excellent adhesion properties, and excellent corrosion resistant properties.
