Powder lacquer composition contains (A) a solid epoxide resin mixture containing an epoxide resin component (A1), consisting of epoxide resin(s) with an overall average epoxide functionality (fav) > 2, and a second epoxide resin component (A2); and (B) a polyester with free carboxyl groups in a amount sufficient for curing the composition. The novelty is that (A2) consists of advancement epoxide resin(s), each with fav NOTLESS 1.2 but < 1.95, and is the production of a simultaneous reaction of (i) diglycidyl compound(s) with (ii) bisphenol compound(s) and (iii) monophenol(s) as educts. The difference between the fav of mixture (A) and component (A2) is NOTLESS 0.2 but < 0.8. Also claimed is a method of producing an epoxide resin mixture.
