Abstract
The present invention provide a recyclable cold curing aqueous coating composition comprising an acrylic group-modified epoxidized ester resin with acid vale of 25 to 60, which is formed from an epoxy resin (a), a fatty acid (b) and an ethylenically unsaturated monomer (c) in a component (a)/component (b)/component (c) weigh % ratio of 20 to 70/20 to 50/3 to 50, the sum of (a), (b) and (c) being 100 weight %, and a method for reusing it. For the method of the present invention, the coating composition has improved recycling properties by optimizing the properties such as acid value of the resin, the pH of a collecting solution for use to collect the coating composition and a content of a hydrophilic solvent in the collecting solution.
