Abstract

The resin system comprises at least two components which can be stored separately and crosslinked with one another at room temperature, preferably without curing accelerators. The first component comprises at least one compound of the formula (I) where A is an unsubstituted or substituted aromatic radical.The second component comprises at least one cyclic anhydride of an organic acid. However, the compound of the formula (I) here is not a compound of the formula (II) where m=1 or 2,if the cyclic anhydride is a compound of the formula (III) where A is a carbonyl radical, or has the formula where each radical Ro is a hydrogen atom or halogen atom, a hydroxyl radical or a C1-C5-alkyl radical or an alkoxy radical, or a C1-C5-alkyl-substituted oxycarbonyl radical, and R′ and R″, independently of one another, are hydrogen atoms or halogen atoms, C1-C5-alkyl groups, nitro groups, carboxyl groups, sulfonyl groups or amino groups.
