ABSTRACT:
A process for preparing an epoxy dimer acid ester resin, which comprises reacting (a) an epoxy resin which is a glycidyl ether of a dihydric phenol having a weight average molecular weight of 1,000 to 30,000 and an epoxy equivalent of 300 to 5,000 with (b) a dimer acid in the presence of an organic solvent having an alcoholic hydroxyl group at a concentration such that the solid content of both reactants (a) and (b) ranges from 60 to 90 percent by weight based on the total weight of the reaction mixture. An epoxy dimer acid ester resin prepared by the process and a coating therefrom are also disclosed. The coating is particularly useful for coating a coil of a steel sheet.
