The invention relates to a binding agent for producing shaped bodies and to shaped bodies produced by using said binding agent which is provided with a content of A) a polymer of 0 to 50 wt. % of at least one ethylenically unsaturated dicarboxylic acid, the anhydrides thereof and/or the salts thereof and 50 to 100 wt. % of at least one ethylenically unsaturated monocarboxylic acid, B) at least one armine that can contain less than two OH groups and is present in an amount so that the pH value of the binding agent ranges from 2 to 7, C) 0.5 to 30 wt. % in relation to solid bodies (A+B) of a cross-linking agent on epoxide or acrylate resin basis and optionally and additionally one polyol with at least two OH groups in an amount of up to 20 wt. % in relation to solid bodies. The shaped bodies that are produced by using said binding agent can be produced in lower temperatures and involving shorter production times and are provided with an improved hygrostability.
