The present invention relates to binder compositions containing sulphonate-functional polyisocyanates and one or more polyorthoester and/or bicyclo orthoester groups which are either chemically incorporated into the sulphonate-functional polyisocyanates or present in admixture with the sulphonate-functional polyisocyanates. The present invention also relates to a process for preparing these binder compositions from either OH functional polyorthoesters or from bicyclo orthoesters, and to coating, adhesive and sealant compositions containing the binder compositions of the invention.
