Abstract:
A process for the production of a water-based dispersion composition, comprising mixing 20 to 80% by weight of a modified epoxy resin (A) as an emulsifying resin and 20 to 80% by weight of an aromatic epoxy resin (B) having a number average molecular weight of 1,000 to 30,000 as a resin to be emulsified to form a mixture and partially or wholly neutralizing the mixture by adding ammonia and/or an amine,the modified epoxy resin (A) being a modified epoxy resin obtained by reacting an aromatic epoxy resin (a1) having an epoxy equivalent of 2,000 to 20,000 with an acrylic resin (a2) having an acid value of 50 to 450 and containing acrylic acid and/or methacrylic acid.
