Zusammenfassung:	PURPOSE:To improve storage stability and corrosion resistance by compounding an unsatd. epoxy ester resin of a specified acid value with a zinc flake and/or a zinc powder and a peroxide compd. as a curing agent. CONSTITUTION:An unsatd. epoxy ester resin (A) with an acid value of 3.0 (mgKOH) or lower is obtd. by reacting an epoxy compd. (a) with 0.1mol or less of total COOH groups of an unsatd. carboxylic acid and, if necessary, a mixture (b) thereof with a satd. carboxylic acid based on 1.0mol of the epoxy group of the component (a) and diluting it, if necessary, with a polymerizable monomer (c) which does not undergo gelation caused by zinc. 100 pts.wt. component A is compounded with 5-100 pts.wt. zinc flaky with a mean length of 10-300mum and a mean thickness of 10mum or less and/or zinc powder (B), a peroxide compd. (C) as a curing agent and, if necessary, an accelerator.
