Abstract

The invention relates to a process for the curing of latently reactive, heat-curable compositions which do not harden at room temperature. The composition includes a polymer obtainable via reaction of certain compounds having two aldehyde groups with polyacrylate compounds having two or more acrylate groups, and also a compound which bears at least two thiol groups.
