The present invention relates to compounds containing modified hydrazide groups and corresponding to formula I Image wherein R represents the residue obtained by removing the isocyanate groups from a monomeric polyisocyanate, a polyisocyanate adduct or an NCO prepolymer, X represents OR' or NHR' and R' represents a group which is inert to isocyanate groups under the conditions used to form the compound of formula I and n has a value of 2 to 6. The present invention also relates to one-component, thermoset coating compositions containing the compounds of formula I and a cross-linking component that is reactive with these compounds. Finally, the present invention relates coatings, sealants and adhesives prepared from these thermoset compositions.
