摘要：
A reactive hardenable binder composition based on(A) at least one aliphatic, cycloaliphatic or aliphatic-cycloaliphatic polyepoxide wherein at least 2 epoxidized cycloaliphatic radicals are bound via an aliphatic bridge,(B) at least one polycarboxylic acid unit of formula ##STR1## having an acid number between 30 and 400 whereinR.sup.1 is a radical of an at least oligomer product selected from the group consisting of polyesters and polymers having initially free OH-groups,R.sup.2 is a radical of a dicarboxylic carbocyclic acid having a COOH-group in ortho-position to its ester bond and(C) a catalyst component of the formula ##STR2## wherein R.sup.3 is a radical of a homo- or copolymer or combination of both of an unsaturated carboxylic acid with a statistically distributed number of COOH side groups or the radical of a polyester having initially free COOH-groups andMe is one equivalent of an alkaline or an alkaline earth metal, thus being present in its salt form, a process for the preparation of hardened products from said composition and a coated article having a coating based on said composition.
